GAAP) to (ii) EBITDA of such Person for the most recent four full fiscal quarters ended on the last day of the most recent fiscal quarter for which internal financial statements are available immediately preceding such Consolidated First Lien Leverage Calculation Date. In the event that the Issuer or any of its Restricted Subsidiaries Incurs, repays, repurchases, defeases or redeems any Indebtedness subsequent to such last day but prior to the Consolidated First Lien Leverage Calculation Date, then the Consolidated First Lien Leverage Ratio shall be calculated giving pro forma effect to such Incurrence, repayment, repurchase, defeasance or redemption of Indebtedness as if the same had occurred at the beginning of the applicable four-quarter period; provided that the Issuer may elect pursuant to an Officers’ Certificate delivered to the Trustee to treat all or any portion of the commitment under any agreement evidencing Indebtedness as being Incurred on the first day of the applicable four-quarter measurement period, in which case any subsequent Incurrence of Indebtedness under such commitment shall not be deemed, for purposes of this calculation, to be an Incurrence at such subsequent time; provided , further , that any Cash Equivalent proceeds received in connection with or as a result of such Incurrence or other transaction for which the Consolidated First Lien Leverage Ratio is being calculated shall not be subtracted from Indebtedness for purposes of calculating the Consolidated First Lien Leverage Ratio.

If since the beginning of such period any Person that subsequently became a Restricted Subsidiary or was merged with or into the Issuer or any Restricted Subsidiary since the beginning of such period shall have made any Investment, acquisition, disposition, merger, amalgamation, consolidation or discontinued operation, in each case, with respect to a business, a division or an operating unit of a business, as applicable, that would have required adjustment pursuant to this definition, then the Consolidated First Lien Leverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition, merger, amalgamation, consolidation or discontinued operation had occurred on the first day of the applicable four-quarter measurement period.

For purposes of this definition, whenever pro forma effect is to be given to any event, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of the Issuer in accordance with the SEC’s Regulation S-X.

ARTICLE 2

THE SECURITIES

SECTION 2.01.                                    Amount of Securities .

(a)                                  The aggregate principal amount of Securities that may be authenticated and delivered under this Indenture is limited to $120,000,000.

(b)                                  On the Issue Date, the Issuer shall issue and deliver, in accordance with this Article 2, Original Securities in an aggregate principal amount of $110,000,000.

(c)                                   On any Business Day on or prior to the one-year anniversary of the Issue Date that does not fall between a Record Date and its related Payment Date (but, for the avoidance of doubt, only one Business Day, but not more than one Business Day), the Issuer may issue and deliver, in accordance with this Article 2, without the consent of any Holder or any holder of beneficial interests in the Original Securities, upon five Business Days’ written notice to the Trustee, Additional Conditional Securities in an aggregate principal amount of up to $10,000,000; provided , that, as of such Business Day, as conditions to the issuance of such Additional Conditional Securities, (i) no Event of Default has occurred and is continuing, (ii) the Issuer shall certify to the initial purchaser(s) of such Additional Conditional Securities that the representations and warranties provided to such initial purchaser(s) (or its or their Affiliates) on the Issue Date shall remain true and correct, (iii) either (A) if the Issuer has repurchased on or after April 4, 2018 (or will repurchase concurrently with the issuance of such Additional Conditional Securities) Convertible Notes owned or beneficially owned by any Person other than an initial purchaser of the Original Securities (or any Affiliate thereof) at a price no greater than 85% of the principal amount of such Convertible Notes, the initial aggregate principal amount of such Additional Conditional Securities is no greater than such price, or (B) at the end of the most recently completed fiscal quarter preceding such Business Day, the Issuer had, for the 12 months ended with the end of such most recently completed fiscal quarter, EBITDA of at least $18,500,000, and (iv) the Issuer shall deliver to the Trustee, in addition to the written order of the Issuer pursuant to Section 2.03, an Officers’ Certificate of the Issuer certifying as to the satisfaction of the foregoing clause (i), clause (ii) and clause (iii), describing in sufficient detail the basis for satisfying such clause (iii). Such Additional Conditional Securities shall have the same terms as the Original Securities, except that the issue date, the initial Payment Date and the initial date from which interest shall accrue may vary. If the Issuer determines that such Additional Conditional Securities are issued as part of a “qualified reopening” for U.S. federal income tax purposes, such Additional Conditional Securities will have the same CUSIP number as the Original Securities and for U.S. federal income tax purposes will have the same issue date and issue price as the Original Securities. If the Issuer determines that such Additional Conditional Securities are not issued as part of a “qualified reopening” for U.S. federal income tax purposes, such Additional Conditional Securities will be

37

required to have a CUSIP number that is different than the CUSIP number of the Original Securities.

(d)                                  The Securities, including any Additional Conditional Securities, shall be treated as a single class for all purposes under this Indenture, including directions provided to the Trustee pursuant to Section 6.05, waivers, amendments, redemptions and offers to purchase, and shall rank on a parity basis in right of payment and security.

SECTION 2.02.                                    Form and Dating . Provisions relating to the Securities are set forth in Appendix A hereto, which is hereby incorporated in and expressly made a part of this Indenture. The Securities and the Trustee’s certificate of authentication shall each be substantially in the form of Exhibit A, which is hereby incorporated in and expressly made a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Issuer or any Guarantor is subject, if any, or usage ( provided that any such notation, legend or endorsement is in a form acceptable to the Issuer). Each Security shall be dated the date of its authentication. The Securities shall be issuable only in registered form, without interest coupons, and in minimum denominations of $250,000 and any integral multiple of $1,000 in excess thereof.

SECTION 2.03.                                    Execution and Authentication . The Trustee shall authenticate and make available for delivery upon a written order of the Issuer signed by one Officer (i) Original Securities for original issue on the Issue Date in an aggregate principal amount of $110,000,000 and (ii) Additional Conditional Securities for original issue pursuant to Section 2.01(c). Such order shall specify the amount of the Securities to be authenticated, the form in which the Securities are to be authenticated and the date on which the original issue of Securities is to be authenticated.

One Officer shall sign the Securities for the Issuer by manual or facsimile signature.

If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

The Trustee may appoint one or more authenticating agents reasonably acceptable to the Issuer to authenticate the Securities. Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities 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 any Registrar, Paying Agent or agent for service of notices and demands.

38

SECTION 2.04.                                    Registrar and Paying Agent .

(a)                                  The Issuer shall maintain (i) an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and (ii) an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Issuer may have one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrars. The term “Paying Agent” includes the Paying Agent and any additional paying agents. The Issuer initially appoints the Trustee as Registrar, Paying Agent and the Securities Custodian with respect to the Global Securities and as Registrar and Paying Agent with respect to the Definitive Securities.

(b)                                  The Issuer may enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee of the name and address of any such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.06. The Issuer or any of its domestically organized Wholly Owned Restricted Subsidiaries may act as Paying Agent or Registrar. Upon any Event of Default as described in Section 6.01(e) or Section 6.01(f), the Trustee shall automatically be the Paying Agent.

(c)                                   The Issuer may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided , however , that no such removal shall become effective until (i) if applicable, acceptance of an appointment by a successor as evidenced by an appropriate agreement entered into by the Issuer and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon written notice to the Issuer and the Trustee; provided , however , that the Trustee may resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee in accordance with Section 7.07.

(d)                                  The Issuer shall promptly deliver to the Trustee (and any Holder upon written request) following the end of each calendar year a written notice specifying the amount of original issue discount, if any, accrued on the outstanding Securities for the previous calendar year, including daily rates and accrual periods, and such other information relating to original issue discount as may be required under the Code and applicable regulations, as amended from time to time.

SECTION 2.05.                                    Paying Agent to Hold Money in Trust . On or prior to each due date of the principal of and interest on any Security, the Issuer shall deposit with each Paying Agent (or if the Issuer or a Wholly Owned Restricted Subsidiary is acting as Paying Agent, segregate and hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal and interest (and any related fees contemplated by this Indenture) when so becoming due. The Issuer shall require each Paying Agent (other than the Trustee) to agree in writing that a Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by a Paying Agent for the payment of principal of and interest on the Securities (and any

39

such related fees), and shall notify the Trustee of any default by the Issuer 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. If the Issuer or a Wholly Owned Restricted Subsidiary of the Issuer acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it in trust for the benefit of the Persons entitled thereto. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee will serve as Paying Agent if not otherwise so acting. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Section 2.05, a Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.06.                                    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 Holders. If the Trustee is not the Registrar, the Issuer shall furnish, or cause the Registrar to furnish, to the Trustee, in writing at least five Business Days before each 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 Holders. The Issuer shall also maintain a copy of such list of the names and addresses of Holders at its registered office.

SECTION 2.07.                                    Transfer and Exchange . The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer and in compliance with Appendix A. When a Security is presented to the Registrar with a request to register a transfer, the Registrar shall register the transfer as requested if its requirements therefor are met. When Securities are presented to the Registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. To permit registration of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Securities at the Registrar’s request. No service charge will be made for any registration of transfer or exchange of the Securities, but the Issuer may require payment from the Holder of a sum sufficient to pay all taxes (including transfer taxes), assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section 2.07. Upon any transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents. The Issuer shall not be required to make, and the Registrar need not register, transfers or exchanges of Securities selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed) or of any Securities for a period of 15 days prior to a selection of Securities to be redeemed.

Prior to the due presentation for registration of transfer of any Security, the Issuer, the Guarantors, the Trustee, the Paying Agent and the Registrar may deem and treat the Person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest, if any, on such Security (and any related fees contemplated by this Indenture) and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Issuer, any Guarantor, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

Any holder of a beneficial interest in a Global Security shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Security may

40

be effected only through a book-entry system maintained by (a) the Holder of such Global Security (or its agent) or (b) any holder of a beneficial interest in such Global Security, and that ownership of a beneficial interest in such Global Security shall be required to be reflected in a book entry.

All Securities issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Securities surrendered upon such transfer or exchange.

SECTION 2.08.                                    Replacement Securities . If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) satisfies the Issuer or the Trustee within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Issuer or the Trustee prior to the Security being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Issuer and the Trustee. If required by the Trustee or the Issuer, such Holder shall furnish an indemnity bond sufficient in the judgment of the Trustee to protect the Trustee, the Paying Agent and the Registrar (if the Registrar also serves as the Paying Agent) and of the Issuer to protect the Issuer, each Guarantor, the Paying Agent and the Registrar (if the Trustee is not serving in the role of Paying Agent or Registrar, as the case may be) from any loss that any of them may suffer if a Security is replaced. The Issuer and the Trustee may charge the Holder for their expenses in replacing a Security (including attorneys’ fees and disbursements in replacing such Security). In the event any such mutilated, lost, destroyed or wrongfully taken Security has become or is about to become due and payable, the Issuer in its discretion may pay such Security instead of issuing a new Security in replacement thereof.

Every replacement Security is an additional obligation of the Issuer and will be entitled to all of the benefits of this Indenture equally and proportionately with all other Securities duly issued hereunder.

The provisions of this Section 2.08 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, lost, destroyed or wrongfully taken Securities.

SECTION 2.09.                                    Outstanding Securities . Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.09 as not outstanding. Subject to Section 12.04, a Security does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Security.

If a Security is replaced pursuant to Section 2.08 (other than a mutilated Security surrendered for replacement), it ceases to be outstanding unless the Trustee and the Issuer receive proof satisfactory to them that the replaced Security is held by a protected purchaser. A

41

mutilated Security ceases to be outstanding upon surrender of such Security and replacement thereof pursuant to Section 2.08.

If the principal amount of any Securities (or portions thereof) and any related fees contemplated by this Indenture are considered paid under Section 4.01, such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

If a Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing and any related fees contemplated by this Indenture, as the case may be, and no Paying Agent is prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.10.                                    Temporary Securities . In the event that Definitive Securities are to be issued under the terms of this Indenture, until such Definitive Securities are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Issuer considers appropriate for temporary Securities. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate Definitive Securities and make them available for delivery in exchange for temporary Securities upon surrender of such temporary Securities at the office or agency of the Issuer, without charge to the Holder. Until such exchange, temporary Securities shall be entitled to the same rights, benefits and privileges as Definitive Securities under this Indenture.

SECTION 2.11.                                    Cancellation . The Issuer at any time may deliver Securities to the Trustee for cancellation. The Registrar and each Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange, payment or cancellation. The Trustee and no one else shall cancel all Securities surrendered for registration of transfer, exchange, payment or cancellation and shall dispose of canceled Securities in accordance with its customary procedures. Certification of the destruction of all cancelled Securities shall be delivered to the Issuer. The Issuer may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for cancellation. The Trustee shall not authenticate Securities in place of canceled Securities other than pursuant to the terms of this Indenture.

SECTION 2.12.                                    Defaulted Interest . If the Issuer defaults in a payment of interest on the Securities, the Issuer shall pay the defaulted interest then borne by the Securities (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Issuer may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. The Issuer shall fix or cause to be fixed any such special record date and payment date and shall promptly provide or cause to be provided to each affected Holder a written notice that states the special record date, the payment date and the amount of defaulted interest to be paid. The special record date for the payment of such defaulted interest shall not be more than 15 days and shall not be less than 10 days prior to the proposed payment date and shall not be less than 10 days after the receipt by the Trustee of the notice of the proposed payment.

42

SECTION 2.13.                                    CUSIP Numbers, ISINs, etc . The Issuer in issuing the Securities may use CUSIP numbers, ISINs and “Common Code” numbers (if then generally in use) and, if so, the Trustee shall use CUSIP numbers, ISINs and “Common Code” numbers in notices (including notices of redemption) as a convenience to Holders; provided , however , that any such notice may state that no representation is made as to the correctness of such numbers, either as printed on the Securities or as contained in any notice that reliance may be placed only on the other identification numbers printed on the Securities and that any such notice shall not be affected by any defect in or omission of such numbers. The Issuer shall advise the Trustee of any change in the CUSIP numbers, ISINs and “Common Code” numbers.

SECTION 2.14.                                    Calculation of Principal Amount of Securities . The aggregate principal amount of the Securities, at any date of determination, shall be the aggregate principal amount of the Securities outstanding at such date of determination. With respect to any matter requiring consent, waiver, approval or other action of the Holders of a specified percentage of the principal amount of all the Securities, such percentage shall be calculated, on the relevant date of determination, by dividing (a) the principal amount, as of such date of determination, of Securities, the Holders of which have so consented, waived, approved or taken other action by (b) the aggregate principal amount, as of such date of determination, of the Securities then outstanding, in each case, as determined in accordance with the preceding sentence, Section 2.09 and Section 12.04. Any such calculation made pursuant to this Section 2.14 shall be made by the Issuer and delivered to the Trustee pursuant to an Officers’ Certificate. The Issuer and the Trustee agree that any action of the Holders may be evidenced by the Depository applicable procedures or by such other procedures as the Issuer and Trustee may agree.

SECTION 2.15.                                    Statement to Holders . After the end of each calendar year but not later than the latest date permitted by applicable law, the Trustee shall (or shall instruct any Paying Agent to) furnish to each Person who at any time during such calendar year was a Holder a statement (for example, a Form 1099 or any other means required by applicable law) prepared by the Trustee containing the interest and original issue discount paid (based solely upon information provided by the Issuer) with respect to the Securities for such calendar year or, in the event such Person was a Holder during only a portion of such calendar year, for the applicable portion of such calendar year, and such other items as may be (a) required pursuant to the then-applicable regulations under the Code or (b) readily available to the Trustee and that a Holder shall reasonably request as necessary for the purpose of such Holder’s preparation of its U.S. federal income or other tax returns. In the event that any such information has been provided by any Paying Agent directly to such Person through other tax-related reports or otherwise, the Trustee in its capacity as Paying Agent shall not be obligated to comply with such request for information.

ARTICLE 3

REDEMPTION

SECTION 3.01.                                    Redemption . The Securities may be redeemed by the Issuer at its option, in whole, or from time to time in part, on any Business Day specified by the Issuer, subject to the conditions and at the redemption prices set forth in Paragraph 5 of the form of

43

Security set forth in Exhibit A, which is hereby incorporated by reference and made a part of this Indenture, together with accrued and unpaid interest to the redemption date.

SECTION 3.02.                                    Applicability of Article . Redemption of Securities at the election of the Issuer or otherwise, as permitted or required by any provision of this Indenture, shall be made in accordance with such provision and this Article 3.

SECTION 3.03.                                    Notices to Trustee . If the Issuer elects to redeem Securities pursuant to the optional redemption provisions of Paragraph 5 of the Security, it shall notify the Trustee and the Holders in writing of (i) the Section of this Indenture and the Paragraph of the Security (if any) pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Securities to be redeemed, (iv) the amount of any related fees contemplated by this Indenture and (v) the redemption price (if then ascertainable).

The Issuer shall provide written notice to the Trustee provided for in this Section 3.03 at least 30 days but not more than 60 days (or such shorter period as may be acceptable to the Trustee) before a redemption date if the redemption is pursuant to Paragraph 5 of the Security. Such notice shall be accompanied by an Officers’ Certificate and Opinion of Counsel from the Issuer to the effect that such redemption will comply with the conditions herein. If fewer than all the Securities are to be redeemed, the record date relating to such redemption shall be selected by the Issuer and given to the Trustee, which record date shall be not fewer than 15 days after the date of notice to the Trustee. Any such notice may be canceled at any time prior to written notice of such redemption being provided to any Holder and shall thereby be void and of no effect.

SECTION 3.04.                                    Selection of Securities to Be Redeemed . In the case of any partial redemption, and if the Securities are Global Securities held by the Depository, the particular Securities or portions thereof to be redeemed shall be allocated on a pro rata pass-through distribution of principal basis in accordance with Depository procedures; provided , that, so long as the Securities are held in book-entry form, the selection for redemption of such Securities shall be made in accordance with the operational arrangements of the Depository then in effect, and if the Depository operational arrangements do not allow for redemption on a pro rata pass-through distribution of principal basis, the Securities will be selected for redemption, in accordance with Depository procedures, by lot. If the Securities are not Global Securities held by the Depository, selection of the Securities for redemption will be made by the Trustee on a pro rata basis to the extent practicable or such other method the Trustee deems fair and appropriate; provided that no Securities of $2,000 or less shall be redeemed in part. The Trustee shall make the selection from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities that have denominations larger than $2,000. Securities and portions of them the Trustee selects shall be in amounts of $2,000 or any integral multiple of $1,000 in excess thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Issuer promptly of the Securities or portions of Securities to be redeemed and the principal amount thereof.

(a)                                  At least 30 days but not more than 60 days before a redemption date pursuant to Paragraph 5 of the Security, the Issuer shall provide or cause to be provided a written notice of redemption to each Holder whose Securities are to be redeemed.

Any such notice shall identify the Securities to be redeemed and shall state:

(vi)                               that, unless the Issuer 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 Securities (or portion thereof) called for redemption ceases to accrue on and after the redemption date;

(vii)                            the CUSIP number, ISIN or “Common Code” number, if any, printed on the Securities being redeemed;

(viii)                         that no representation is made as to the correctness or accuracy of the CUSIP number or ISIN or “Common Code” number, if any, listed in such notice or printed on the Securities; and

(ix)                               such other matters as the Issuer deems desirable or appropriate.

Notice of any redemption pursuant to this Section 3.05 may, at the Issuer’s direction, be revocable and be subject to one or more conditions precedent, including the receipt by the Trustee, on or prior to the redemption date, of money sufficient to pay the principal of, and premium, if any, and interest on, the Securities being redeemed and any related fees contemplated by this Indenture.

In such event, the Issuer shall provide the Trustee a notice containing the information required by this Section 3.05 at least five Business Days (unless the Trustee consents to a shorter period) prior to the date such notice is to be provided to

45

Holders and such notice may not be canceled but may be subject to such conditions precedent as shall be set forth in such notice.

SECTION 3.06.                                    Effect of Notice of Redemption . Once written notice of redemption is provided in accordance with Section 3.05, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, subject to the satisfaction or waiver of any conditions precedent in the notice of redemption. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued and unpaid interest, to, but not including, the redemption date; provided , however , that if the redemption date is after a Record Date and on or prior to the related Payment Date, the accrued and unpaid interest shall be payable to the Holder of the redeemed Securities registered on such Record Date.

Upon redemption of any Securities by the Issuer, such redeemed Securities will be cancelled.

SECTION 3.08.                                    Securities Redeemed in Part .

SECTION 4.22.                                    Special Proceeds .

(a)                                  No later than 30 days following the date of receipt by the Issuer or any of its Restricted Subsidiaries, or the Collateral Agent as loss payee, of any Special Proceeds, the Issuer shall make an offer to all Holders of Securities (a “Special Proceeds Offer”) to repurchase

68

the maximum principal amount of Securities that is at least $2,000 and an integral multiple of $1,000 that may be repurchased out of the Special Proceeds at a repurchase price in cash equal to the redemption price set forth in Paragraph 5 of the Form of Security set forth in Exhibit A that would be applicable to such Securities on the date fixed for such repurchase (the “Special Proceeds Repurchase Date”), plus accrued and unpaid interest, if any, to the Special Proceeds Repurchase Date (subject to the right of the Holders of record on the relevant Record Date to receive interest due on the related Payment Date), plus a fee equal to 1.00% of the principal amount repurchased on the Special Proceeds Repurchase Date, in accordance with the terms contemplated in this Section 4.22; provided , however , that notwithstanding the receipt of Special Proceeds, the Issuer shall not be obligated to repurchase any Securities pursuant to this Section 4.22 in the event that it has exercised (i) its unconditional right to redeem such Securities in accordance with Article 3 or (ii) its legal defeasance option or covenant defeasance option in accordance with Article 8. The Issuer shall commence the Special Proceeds Offer by providing the written notice required pursuant to Section 4.22(e), with a copy provided contemporaneously therewith to the Trustee. To the extent that the aggregate principal amount of Securities tendered pursuant to a Special Proceeds Offer is less than the Special Proceeds, the Issuer (or the applicable Restricted Subsidiary of the Issuer) may use any remaining Special Proceeds for any purpose that is not prohibited by this Indenture. If the aggregate principal amount of Securities tendered pursuant to a Special Proceeds Offer exceeds the Special Proceeds, the selection of the Securities to be repurchased shall be made in the manner described in Section 4.22(d). Upon completion of any such Special Proceeds Offer, the amount of Special Proceeds shall be reset at zero.

(b)                                  The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the extent such laws or regulations are applicable in connection with the repurchase of the Securities pursuant to a Special Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuer shall 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.

(c)                                   Not later than the date upon which written notice of a Special Proceeds Offer is delivered to the Trustee as provided above, the Issuer shall deliver to the Trustee an Officers’ Certificate as to the amount of the Special Proceeds. On the Special Proceeds Repurchase Date, the Issuer shall irrevocably deposit or cause to be deposited with the Trustee or with a Paying Agent (or, if the Issuer or a domestically organized Wholly Owned Restricted Subsidiary is acting as the Paying Agent, segregate and hold in trust) an amount equal to the Special Proceeds to be invested in Cash Equivalents, as directed in writing by the Issuer, and to be held for payment in accordance with the provisions of this Section 4.22. Upon the expiration of the period for which the Special Proceeds Offer remains open (the “Special Proceeds Offer Period”), the Issuer shall deliver to the Trustee for cancellation the Securities or portions thereof that have been properly tendered to and are to be accepted by the Issuer, along with a written payment and cancellation order. The Trustee (or the Paying Agent, if not the Trustee) shall, on the Special Proceeds Repurchase Date, mail or otherwise deliver payment to each tendering Holder in the amount of the repurchase price as determined by the Issuer and stated in the written payment and cancellation order. In the event that the Special Proceeds delivered by or caused to be delivered by the Issuer to the Trustee are greater than the repurchase price of the Securities

69

tendered, the Trustee shall remit the excess to the Issuer immediately after the expiration of the Special Proceeds Offer Period for application in accordance with this Section 4.22.

(d)                                  Holders electing to have a Security repurchased pursuant to a Special Proceeds Offer shall be required to surrender the Security, with an appropriate form duly completed, to the Issuer at the address specified in the notice provided pursuant to this Section 4.22 at least three Business Days prior to the Special Proceeds Repurchase Date. Holders shall be entitled to withdraw their election if the Issuer receives not later than one Business Day prior to the Special Proceeds Repurchase Date a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security that was delivered by the Holder for repurchase and a statement that such Holder is withdrawing such Holder’s election to have such Security repurchased. If at the end of the Special Proceeds Offer Period more Securities are tendered pursuant to a Special Proceeds Offer than the Issuer is required to repurchase, and if the Securities are Global Securities held by the Depository, the particular Securities or portions thereof to be repurchased shall be allocated on a pro rata pass-through distribution of principal basis in accordance with Depository procedures; provided , that, so long as the Securities are held in book-entry form, the selection for repurchase of such Securities shall be made in accordance with the operational arrangements of the Depository then in effect, and if the Depository operational arrangements do not allow for repurchase on a pro rata pass-through distribution of principal basis, the Securities will be selected for repurchase, in accordance with Depository procedures, by lot. If the Securities are not Global Securities held by the Depository, selection of such Securities for repurchase shall be made by the Trustee on a pro rata basis to the extent practicable or such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with applicable legal requirements); provided that no Securities of $2,000 or less shall be repurchased in part.

(e)                                   Written notice of a Special Proceeds Offer shall be provided at least 30 but not more than 60 days before the Special Proceeds Repurchase Date to each Holder of Securities at such Holder’s registered address (or electronically pursuant to the Depository’s applicable procedures), with a copy to the Trustee. If any Security is to be repurchased in part only, any notice of repurchase that relates to such Security shall state the portion of the principal amount thereof that has been or is to be repurchased. Holders whose Securities are repurchased only in part shall be issued new Securities equal in principal amount to the portion of the Securities surrendered but not repurchased. If the Securities are Global Securities held by the Depository, then the applicable operational procedures of the Depository for tendering and withdrawing securities will apply.

(h)                                  any representation or warranty made in writing by or on behalf of the Issuer or any Guarantor in connection with the issuance and sale of the Securities or made in writing by or on behalf of the Issuer or any Guarantor or by any officer of the Issuer or any Guarantor furnished in connection with the transactions contemplated by this Indenture and the Security Documents proves to have been false or incorrect in any material respect on the date as of which made (or, if such representation or warranty is given as of a specific time, as of such time);

The foregoing shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

The term “Bankruptcy Law” means Title 11, United States Code, or any similar U.S. federal or state law for the relief of debtors (or their non-U.S. equivalents). The term

74

“Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

A Default under clause (c) or (l) above shall not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities notify the Issuer (and also the Trustee if given by the Holders) of the Default or after the date on which such Default should reasonably have been known or been aware of by the defaulting party and the Issuer does not cure such Default within the time specified in such clause (c) or (l) after receipt of such notice or after such date, as applicable. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default”. The Issuer shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any event that is, or with the giving of notice or the lapse of time or both would become, an Event of Default, its status and what action the Issuer is taking or proposes to take in respect thereof.

SECTION 6.02.                                    Acceleration . If an Event of Default (other than an Event of Default specified in Section 6.01(e) or 6.01(f) with respect to the Issuer) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding Securities by written notice to the Issuer may, and if such notice is given by the Holders such notice shall be given to the Issuer and the Trustee, declare that the principal of, and the premium, if any, and accrued but unpaid interest on, all the Securities and any related fees contemplated by this Indenture is due and payable. Upon such a declaration, such principal and interest and related fees shall be due and payable immediately. If an Event of Default specified in Section 6.01(e) or 6.01(f) with respect to the Issuer occurs, the principal of, and the premium, if any, and accrued but unpaid interest on, all the Securities and any related fees contemplated by this Indenture shall ipso facto become and be immediately due and payable, without any declaration or other act on the part of the Trustee or any Holders. The Holders of a majority in principal amount of the Securities by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium and any related fees that has become due solely because of the acceleration) have been cured or waived.

If the principal of, or premium, if any, or accrued and unpaid interest, if any, on, the Securities and any related fees becomes due and payable as provided above (an “Acceleration”), the principal of, and the premium, if any, and accrued but unpaid interest on, the Securities (and any related fees) that becomes due and payable shall equal the optional redemption price in effect on the date of such declaration (or the date set forth in the third sentence of this Section 6.02), as if such Acceleration were an optional redemption of the Securities effected thereby on such date of declaration (or the date set forth in the third sentence of this Section 6.02). The amounts described in the preceding sentence are intended to be liquidated damages and not unmatured interest or a penalty.

In the event of any Event of Default specified in Section 6.01(d), such Event of Default and all consequences thereof (excluding, however, any resulting payment default) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders of the Securities, if within 20 days after such Event of Default arose the Issuer delivers an Officers’ Certificate to the Trustee stating that (x) the Indebtedness or guarantee that is the

75

basis for such Event of Default has been discharged, (y) the Holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (z) the default that is the basis for such Event of Default has been cured, it being understood that in no event shall an acceleration of the principal amount of the Securities as described above be annulled, waived or rescinded upon the happening of any such events.

SECTION 6.03.                                    Other Remedies . If an Event of Default occurs and is continuing, the Trustee may, but only at the written direction of Holders of a majority in principal amount of the then outstanding Securities, pursue any available remedy at law or in equity to collect the payment of principal of or interest on the Securities and any related fees contemplated by this Indenture or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder 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. No remedy is exclusive of any other remedy. To the extent required by law, all available remedies are cumulative.

SECTION 6.04.                                    Waiver of Past Defaults . Provided the Securities are not then due and payable by reason of a declaration of acceleration, the Holders of a majority in principal amount of the then outstanding Securities by written notice to the Trustee may waive an existing Default and its consequences except (a) a Default in the payment of the principal of or interest on a Security or any related fees contemplated by this Indenture, (b) a Default arising from the failure to redeem or purchase any Security when required pursuant to the terms of this Indenture or (c) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected. When a Default is waived, it is deemed cured and the Issuer, the Trustee and the Holders will be restored to their former positions and rights under this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. Any past Default or compliance with any provisions may be waived with the consent of the Holders of a majority in principal amount of the Securities then outstanding.

SECTION 6.05.                                    Control by Majority . The Holders of a majority in principal amount of the then outstanding Securities 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 direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. Prior to taking any action under this Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

76

SECTION 6.06.                                    Limitation on Suits .

(a)                                  Except to enforce the right to receive payment of principal, premium (if any) or interest and any related fees contemplated by this Indenture when due, no Holder may pursue any remedy with respect to this Indenture or the Securities unless:

(i)                                      the Holder gives the Trustee written notice stating that an Event of Default is continuing;

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

(iii)                                such Holder or Holders offer to the Trustee security or indemnity satisfactory to it against any loss, liability or expense;

(iv)                               the Trustee does not comply with the request within 60 days after receipt of the request and the offer of security or indemnity; and

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

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

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on the Securities held by such Holder and any related fees contemplated by this Indenture, on or after the respective due dates expressed or provided for in this Indenture or in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

SECTION 6.08.                                    Collection Suit by Trustee . If an Event of Default specified in Section 6.01(a) or Section 6.01(b) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on the Securities for the whole amount then due and owing (together with interest on overdue principal and any related fees contemplated by this Indenture and (to the extent lawful) on any unpaid interest at the rate provided for in the Securities) and the amounts provided for in Section 7.06.

SECTION 6.09.                                    Trustee May File Proofs of Claim . The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation, expenses disbursements and advances of the Trustee (including counsel, accountants, experts or such other professionals as the Trustee deems necessary, advisable or appropriate)) and the Holders allowed in any judicial proceedings relative to the Issuer or any Guarantor, their creditors or their property, shall be entitled to participate as a member, voting or otherwise, of any official committee of creditors appointed in such matters and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other

77

Person performing similar functions and be a member of a creditors’ or other similar committee, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.06.

SECTION 6.10.                                    Priorities . If the Trustee collects any money or property pursuant to this Article 6 or any Security Document, the Trustee (after giving effect to Section 5.3 of the Collateral Agreement) shall pay out the money or property in the following order:

FIRST: to the Trustee for amounts due under Section 7.06;

SECOND: to the Holders for amounts due and unpaid on the Securities for principal, premium, if any, and interest, and any related fees contemplated by this Indenture, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal, premium, if any, and interest, and any related fees contemplated by this Indenture, respectively; and

SECTION 6.11.                                    Undertaking for Costs .

This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in principal amount of the Securities.

SECTION 6.12.                                    Waiver of Stay or Extension Laws . Neither the Issuer nor any Guarantor (to the extent it may lawfully do so) shall at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Issuer and each Guarantor (to the extent that it may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

After an amendment under this Section 9.01 becomes effective, the Issuer shall provide to the Holders a written notice briefly describing such amendment.

(ii)                                   reduce the rate of or extend the time for payment of interest on any Security;

(iii)                                reduce the principal of or change the Stated Maturity of any Security (or reduce the amount of any payment of any installment of principal or change the due date in respect of the payment of any installment of principal) or reduce any fee payable under this Indenture calculated with reference to the principal of the Securities or change the due date therefor;

(iv)                               reduce the premium payable upon the redemption or repurchase of any Security or change the time at which any Security may be redeemed or repurchased in accordance with Article 3, Section 4.08 or Section 4.22;

(vii)                            impair the right of any Holder to receive payment of principal of or premium, if any, and interest on such Holder’s Securities on or after the due dates (or the due date in respect of the payment of any installment of principal) therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Securities or to receive any fee payable under this Indenture calculated with reference to the principal of the Securities on or after the due dates therefor or to institute suit for the enforcement of any payment thereon or with respect thereto;

(viii)                         make any change in Section 6.04 or the second sentence of this Section 9.02;

Without the consent of the Holders of at least two-thirds in aggregate principal amount of the Securities then outstanding, no amendment, supplement or waiver may release all or substantially all of the Collateral from the Liens of this Indenture and the Security Documents with respect to the Securities.

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment if such consent approves the substance thereof.

(b)                                  After an amendment under this Section 9.02 becomes effective, the Issuer shall provide to the Holders a written notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02.

SECTION 9.03.                                    Revocation and Effect of Consents and Waivers .

(a)                                  A consent to an amendment, supplement or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent, supplement or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent, supplement or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date on which the Trustee receives an Officers’ Certificate from the Issuer certifying that the requisite principal amount of Securities have consented. After an amendment, supplement or waiver becomes effective, it shall bind every Holder. An amendment, supplement or waiver becomes effective upon the (i) receipt by the Issuer or the Trustee of consents by the Holders of the requisite

91

principal amount of Securities, (ii) satisfaction of conditions to effectiveness as set forth in this Indenture and any indenture supplemental hereto containing such amendment, supplement or waiver, (iii) execution of such amendment or waiver (or supplemental indenture) by the Issuer and the Trustee and (iv) delivery to the Trustee of the Officers’ Certificate and Opinion of Counsel required under Article 12.

(b)                                  The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding Section 9.03(a), those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date.

SECTION 9.04.                                    Notation on or Exchange of Securities . If an amendment, supplement or waiver changes the terms of a Security, the Issuer may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Issuer or the Trustee so determines, the Issuer in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment, supplement or waiver.

SECTION 9.05.                                    Trustee to Sign Amendments . The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment, the Trustee shall be entitled to receive indemnity satisfactory to it and shall be provided with, and (subject to Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment, supplement or waiver is authorized or permitted by this Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Issuer and the Guarantors, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 9.03). Notwithstanding the foregoing, no Opinion of Counsel will be required for the Trustee to execute any amendment or supplement adding a new Guarantor under this Indenture.

SECTION 9.06.                                    Payment for Consent . Neither the Issuer nor any Affiliate of the Issuer shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Securities unless such consideration is offered to be paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement.

SECTION 9.07.                                    Additional Voting Terms; Calculation of Principal Amount . All Securities issued under this Indenture shall vote and consent together on all matters (as to which any of such Securities may vote) as one class. Determinations as to whether Holders of the

92

requisite aggregate principal amount of Securities have concurred in any direction, waiver or consent shall be made in accordance with this Article 9 and Section 2.14.

ARTICLE 10

GUARANTEES

SECTION 10.01.                             Guarantees .

(a)                                  Each Guarantor hereby jointly and severally irrevocably and unconditionally guarantees as a primary obligor and not merely as a surety on a senior basis to each Holder, the Trustee, the Collateral Agent and their respective successors and assigns (i) the full and punctual payment when due, whether at Stated Maturity, by acceleration, by redemption or otherwise, of all Obligations of the Issuer under this Indenture (including obligations to the Trustee) and the Securities, whether for payment of principal of, or premium, if any, or interest, if any, on, the Securities and all other monetary obligations of the Issuer under this Indenture and the Securities, and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Issuer, whether for fees, expenses, indemnification or otherwise under this Indenture and the Securities, on the terms set forth in this Indenture by becoming a party to this Indenture (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”).

(b)                                  Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from each such Guarantor, and that each such Guarantor shall remain bound under this Article 10 notwithstanding any extension or renewal of any Guaranteed Obligation. The Guaranteed Obligations of a Guarantor will be secured by security interests (subject to Permitted Liens) in the Collateral owned by such Guarantor to the extent provided for in the Security Documents and as required pursuant to Sections 4.13 and 4.16.

(c)                                   Each Guarantor waives presentation to, demand of payment from and protest to the Issuer of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Guarantor hereunder shall not be affected by (i) the failure of any Holder, the Trustee or the Collateral Agent to assert any claim or demand or to enforce any right or remedy against the Issuer or any other Person under this Indenture, the Securities, any Security Document, or any other agreement or otherwise; (ii) any extension or renewal of this Indenture, the Securities, any Security Document or any other agreement; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities, any Security Document or any other agreement; (iv) the release of any security held by any Holder, the Trustee or the Collateral Agent for the Guaranteed Obligations or any Guarantor; (v) the failure of any Holder, the Trustee or the Collateral Agent to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (vi) any change in the ownership of such Guarantor, except as provided in Section 10.03.

(d)                                  Each Guarantor hereby waives any right to which it may be entitled (except as may be required by applicable requirements of law or regulation and to the extent the

93

relevant requirement cannot be waived) to (i) have its obligations hereunder divided among the Guarantors, such that such Guarantor’s obligations would be less than the full amount claimed, (ii) have the assets of the Issuer or any other Guarantor first be used and depleted as payment of the Issuer’s or such Guarantor’s obligations hereunder prior to any amounts being claimed from or paid by such Guarantor hereunder and (iii) require that the Issuer be sued prior to an action being initiated against such Guarantor.

(e)                                   Each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder, the Trustee or the Collateral Agent to any security held for payment of the Guaranteed Obligations.

(f)                                    Except as expressly set forth in Sections 8.01, 10.02, 10.03 and 10.06, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim (other than payment in full) of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by (i) the failure of any Holder, the Trustee or the Collateral Agent to assert any claim or demand or to enforce any remedy under this Indenture, the Securities, any Security Document or any other agreement, (ii) any waiver or modification of any thereof, (iii) any default, failure or delay, willful or otherwise, in the performance of the obligations, or (iv) any other act or thing or omission or delay to do any other act or thing that may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of any Guarantor as a matter of law or equity.

(g)                                   Except as expressly set forth in Sections 8.01 and 10.03, each Guarantor agrees that its Guarantee shall remain in full force and effect until payment in full of its Guaranteed Obligations. Except as expressly set forth in Sections 8.01 and 10.03, each Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Issuer or otherwise.

(h)                                  In furtherance of the foregoing and not in limitation of any other right that any Holder, the Trustee or the Collateral Agent has at law or in equity against any Guarantor by virtue hereof, at any time when an Event of Default pursuant to Section 6.01(a) or 6.01(b) has occurred and is continuing or upon the failure of the Issuer to perform or comply with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee in accordance with this Indenture, forthwith pay, or cause to be paid, in cash, to the Holders, the Trustee or the Collateral Agent an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by applicable law) and (iii) all other monetary obligations of the Issuer then due to the Holders, the Trustee and the Collateral Agent in respect of the Guaranteed Obligations.

94

(j)                                     Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee, the Collateral Agent or any Holder in enforcing any rights under this Section 10.01.

(k)                                  Each Guarantor shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

SECTION 10.02.                             Limitation on Liability . Each Guarantor and, by its acceptance of Securities, each Holder hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor does not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar U.S. federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under this Indenture, can be guaranteed hereby without rendering the Guarantee, as it relates to such Guarantor, void or voidable under applicable laws relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. Each Guarantor that makes a payment under its Guarantee shall be entitled upon payment in full of all Guaranteed Obligations under this Indenture to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective maximum liability of all the Guarantors at the time of such payment.

SECTION 10.03.                             Releases . A Guarantee as to any Guarantor shall terminate and be of no further force or effect and such Guarantor shall be deemed to be automatically and unconditionally released from all obligations under this Article 10 upon:

(a)                                  the sale, disposition, exchange or other transfer (including through merger, amalgamation, consolidation or otherwise) of the Capital Stock of the applicable Guarantor if (x) such sale, disposition, exchange or other transfer is made to a Person that is not the Issuer or a

95

Restricted Subsidiary in a manner not in violation of this Indenture and (y) after giving effect to such sale, disposition, exchange or other transfer, such Guarantor is no longer a Restricted Subsidiary;

(b)                                  the Issuer designating such Guarantor to be an Unrestricted Subsidiary in accordance with the provisions set forth in Section 4.04 and the definition of “Unrestricted Subsidiary”;

(d)                                  the Issuer’s exercise of the Issuer’s legal defeasance option or covenant defeasance option in accordance with Section 8.01 or if the obligations of the Issuer and such Guarantor under this Indenture are discharged in accordance with the terms of this Indenture.

SECTION 10.04.                             Successors and Assigns . This Article 10 shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of the Trustee, the Collateral Agent and the Holders and their successors and assigns and, in the event of any transfer or assignment of rights by any Holder, the Collateral Agent or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 10.05.                             No Waiver . Neither a failure nor a delay on the part of the Trustee, the Collateral Agent or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege.

SECTION 10.06.                             Modification . No modification, amendment or waiver of any provision of this Article 10, nor the consent to any departure by any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 10.07.                             Execution of Supplemental Indenture for Future Guarantors . Each Person that is required to become a Guarantor after the Issue Date pursuant to Section 4.12 shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit C pursuant to which such Person shall become a Guarantor under this Article 10 and shall guarantee the Guaranteed Obligations. In the case where a supplemental indenture is entered into under this Section 10.07 solely for purposes of adding a Guarantor, no Opinion of Counsel shall

96

be required; provided , that if the Trustee so requests, an Officers’ Certificate that all conditions precedent to execution have been satisfied shall be delivered.

SECTION 10.08.                             No Impairment . The failure to endorse a Guarantee on any Security shall not affect or impair the validity thereof. If an Officer whose signature is on this Indenture or the notation of Guarantee no longer holds that office at the time the Trustee authenticates the Securities, the Guarantee shall be valid nevertheless.

SECTION 10.09.                             Benefits Acknowledged . Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the guarantee and waivers made by it pursuant to its Guarantee are knowingly made in contemplation of such benefits.

The Issuer and the Guarantors will be entitled to a release of assets included in the Collateral from the Liens securing the Securities, and the Trustee shall promptly release, or instruct the Collateral Agent to promptly release, as applicable, the Issuer and/or such Guarantors from such Liens at the Issuer’s sole cost and expense, under one or more of the following circumstances:

(1)                                  to enable the Issuer or any Restricted Subsidiary to sell, exchange or otherwise dispose of any of the Collateral to any Person other than the Issuer or any Guarantor (but excluding any transaction subject to Article 5 where the recipient is required to become the obligor on the Securities or a Guarantee) to the extent not prohibited by this Indenture, including Section 4.06;

Upon receipt of an Officers’ Certificate certifying that all conditions precedent under this Indenture and the Security Documents, if any, to such release have been met and any necessary or proper (as determined by the Issuer) instruments of termination, satisfaction or release have been prepared by the Issuer, the Collateral Agent shall promptly execute, deliver or acknowledge (at the Issuer’s expense) such instruments or releases to evidence the release of any Collateral permitted to be released pursuant to this Indenture or the Security Documents.

(b)                                  At any time when a Default or Event of Default has occurred and is continuing and the maturity of the Securities has been accelerated (whether by declaration or otherwise) and the Trustee (if not then also appointed and serving as Collateral Agent) has delivered a notice of acceleration to the Collateral Agent, no release of Collateral pursuant to the provisions of this Indenture or the Security Documents will be effective as against the Holders.

SECTION 11.04.                             Permitted Releases Not To Impair Lien . The release of any Collateral from the terms hereof and of the Security Documents or the release of, in whole or in part, the Liens created by the Security Documents, will not be deemed to impair the security under this Indenture in contravention of the provisions hereof if and to the extent the Collateral or Liens are released pursuant to the applicable Security Documents and the terms of this Article 11. Each of the Holders acknowledges that a release of Collateral or a Lien in accordance with the terms of the Security Documents and of this Article 11 will not be deemed for any purpose to be in contravention of the terms of this Indenture.

SECTION 11.05.                             Suits To Protect the Collateral . Subject to the provisions of Article 7, at any time that an Event of Default has occurred and is continuing, the Trustee in its sole discretion and without the consent of the Holders, on behalf of the Holders, may or may direct the Collateral Agent to take all actions it deems necessary or appropriate in order to:

(a)                                  enforce any of the terms of the Security Documents; and

(b)                                  collect and receive any and all amounts payable in respect of the Guaranteed Obligations of the Issuer hereunder.

Except as otherwise explicitly provided herein or in the Security Documents, neither the Collateral Agent nor any of its officers, directors, employees or agents shall be liable for failure to demand, collect

or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. Notwithstanding any provision to the contrary contained elsewhere in this Indenture or the Security Documents, the duties of the Collateral Agent shall be ministerial and administrative in nature, and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth in this Indenture and in the Security Documents to which the Collateral Agent is a party, nor shall the Collateral Agent have or be deemed to have any trust or other fiduciary relationship with the Trustee, any Holder, the Issuer or any Guarantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture or the Security Documents or shall otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” or “Agent” in this Indenture and the Security Documents with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom and is intended to create or reflect only an administrative relationship between independent contracting parties. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither the Collateral Agent nor any of its officers, directors, employees or agents shall be responsible for any act or failure to act hereunder, except for its own willful misconduct or gross negligence (as determined by a final, non-appealable order of a court of competent jurisdiction).

(b)                                  The Collateral Agent is authorized and directed to (i) enter into the Security Documents, (ii) bind the Holders on the terms as set forth in the Security Documents and (iii) perform and observe its obligations under the Security Documents.

(c)                                   The Collateral Agent shall act pursuant to the instructions of the Holders and the Trustee with respect to the Security Documents and the Collateral. For the avoidance of doubt, the Collateral Agent shall have no discretion under this Indenture or the Security Documents and shall not be required to make or give any determination, consent, approval, request or direction without the written direction of the requisite Holders or the Trustee, as applicable. After the occurrence of an Event of Default, the Trustee may direct the Collateral Agent in connection with any action required or permitted by this Indenture or the Security Documents.

(d)                                  The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless the Collateral Agent shall have received written notice from the Trustee, a Holder or the Issuer referring to this Indenture, describing such Default or Event of Default and stating that such notice is a “notice of default”. The Collateral Agent shall take such action with respect to such Default or Event of Default as may be requested by the Trustee or the Holders of a majority in aggregate principal amount of the Securities subject to this Article 11.

(e)                                   No provision of this Indenture or any Security Document shall require the Collateral Agent (or the Trustee) to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or thereunder or to take or omit to take any action hereunder or thereunder or take any action at the request or direction of Holders (or
