such notation, legend or endorsement is in a form acceptable to the Company). Each Security shall be dated the date of its authentication. The terms of the Securities set forth in the Appendix and Exhibit A are part of the terms of this Indenture.

SECTION 2.02. Execution and Authentication. Two Officers shall sign the Securities 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.

On the Issue Date, the Trustee shall authenticate and deliver $290,000,000 of 10.5% Senior Second Lien Notes due 2018 and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Securities for original issue in an aggregate principal amount specified in such order, in each case upon a written order of the Company signed by two Officers.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the Securities. 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.

SECTION 2.03. Registrar and Paying Agent. The Company shall maintain an office or agency (which may be the office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency (which may be the office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) 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 Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent.

The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company 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 7.07. The Company or any Wholly Owned Subsidiary incorporated or organized within the United States of America may act as Paying Agent, Registrar, co-registrar or transfer agent.

The Company initially appoints the Trustee as Registrar and Paying Agent in connection with the Securities.

SECTION 2.04. Paying Agent To Hold Money in Trust. The Company shall deposit with the Paying Agent a sum sufficient to pay such principal and interest when due on the dates and in the manner provided in the Securities. Principal, premium, if any, and interest will be considered paid on the date due if the Paying Agent holds (as of 12:00 p.m., New York City time, on the due date) money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal and premium, if any, and interest, if any, then due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary of the Company acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company 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 the Paying Agent. Upon complying with this Section 2.04, the Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.05. Securityholder 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 Securityholders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least five 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 Securityholders.

SECTION 2.06. Transfer and Exchange. The Initial Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer. The Private Placement Securities shall be delivered in certificated form without interest coupons, subject to the transfer restrictions set forth in 2.3(c) of the Appendix. When a Security is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(a) of the Uniform Commercial Code are met. When Securities are presented to the Registrar or a co-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.

SECTION 2.07. Replacement Securities. If a mutilated Security in certificated form is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405

of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond that is sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Security.

SECTION 2.08. 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 as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

If a Security is replaced pursuant to Section 2.07, the replaced Security ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser (as defined in Section 8-303 of the Uniform Commercial Code).

If the 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, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.09. Temporary Securities. Until definitive Securities are ready for delivery, the Company 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 Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities.

SECTION 2.10. Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and dispose of (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancellation and deliver a certificate of such disposition to the Company unless the Company directs the Trustee to deliver canceled Securities to the Company. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for cancellation.

SECTION 2.11. Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company shall pay defaulted interest (plus

interest on such defaulted interest to the extent lawful) in any lawful manner at the rate provided in the Securities and Section 4.01 hereof. The Company may pay the defaulted interest at the rate provided in the Securities and Section 4.01 hereof to the persons who are Holders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly mail to each Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

SECTION 2.12. CUSIP Numbers, ISINs, etc. The Company in issuing the Securities may use “CUSIP” numbers, ISINs and “Common Code” numbers (in each case if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers, ISINs and “Common Code” numbers in a notice 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 of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall advise the Trustee in writing of any change in any “CUSIP” numbers, ISINs or “Common Code” numbers applicable to the Securities.

SECTION 2.13. Issuance of Additional Securities. After the Issue Date, the Company shall be entitled, subject to its compliance with Section 4.03, to issue Additional Securities under this Indenture, which Securities shall have identical terms as the Initial Securities issued on the Issue Date, other than with respect to the date of issuance and issue price. All the Securities issued under this Indenture shall be treated as a single class for all purposes of this Indenture including waivers, amendments, redemptions and offers to purchase.

With respect to any Additional Securities, the Company shall set forth in a resolution of the Board of Directors and an Officers’ Certificate, a copy of each which shall be delivered to the Trustee, the following information:

(1) the aggregate principal amount of such Additional Securities to be authenticated and delivered pursuant to this Indenture and the provision of Section 4.03 that the Company is relying on to issue such Additional Securities;

(2) the issue price, the issue date and the CUSIP number of such Additional Securities, if any; provided, however, that only those Additional Securities that are part of the “same issue” as all other Securities issued under this Indenture, as defined under Treasury Regulation Section 1.1275-1(f), or issued in a “qualified reopening” under Treasury Regulation Section 1.1275-2(k) will be issued with the same CUSIP number as the other Securities issued under this Indenture; and

(3) whether such Additional Securities shall be issued in the form of Initial Securities as set forth in Exhibit 1 or shall be issued in the form of Exchange Securities as set forth in Exhibit A.

SECTION 3.01. Notice to Trustee. If the Company elects to redeem Securities pursuant to Section 6 of the Securities, it shall notify the Trustee in writing of the redemption date, the principal amount of Securities to be redeemed and the paragraph of the Securities pursuant to which the redemption will occur.

The Company shall give each notice to the Trustee provided for in this Section at least 30 days before the redemption notice date unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officers’ Certificate and an Opinion of Counsel from the Company to the effect that such redemption will comply with the conditions herein.

SECTION 3.02. Selection of Securities to Be Redeemed. If fewer than all the Securities are to be redeemed, the Trustee shall select the Securities to be redeemed pro rata to the extent practicable, or to the extent not so practicable, by lot or such other method as the Trustee in its sole discretion shall deem to be fair and appropriate, unless another method is required by law or applicable exchange or depositary requirements. The Trustee shall make the selection from outstanding Securities not previously called for redemption. Securities and portions of Securities the Trustee selects shall be in principal amounts of $2,000 or any greater integral multiple of $1,000 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 Company promptly of the Securities or portions of Securities to be redeemed.

SECTION 3.03. Notice of Redemption. At least 30 days but not more than 60 days before a date for redemption of Securities, the Company shall mail a notice of redemption by first-class mail to each Holder of Securities to be redeemed at such Holder’s registered address, except that a redemption notice may be mailed more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of the Securities or a satisfaction and discharge of this Indenture pursuant to Article 8. Any defect in the notice of redemption, including a failure to give notice, to any Holder selected for redemption shall not impair or affect the validity of the redemption of any other Securities redeemed in accordance with provisions of this Indenture. A notice of redemption may be subject to one or more conditions precedent, including the consummation of an Equity Offering or other financing transaction.

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

(5) if fewer than all the outstanding Securities are to be redeemed, the identification and principal amounts of the particular Securities to be redeemed;

(6) that, unless the Company defaults in making such redemption payment, interest on Securities (or portion thereof) called for redemption ceases to accrue on and after the redemption date;

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

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

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense. In such event, the Company shall provide the Trustee with the information required by this Section 3.03, at least 40 days (unless a shorter time shall also be acceptable to the Trustee) prior to the redemption date.

SECTION 3.04. Effect of Notice of Redemption. Once notice of redemption is mailed, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, and from and after such redemption date (unless the Company defaults in the payment of the redemption price and accrued and unpaid interest), such Securities will cease to bear interest. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued interest to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the related interest payment date), and such Securities shall be canceled by the Trustee. Failure to give notice or any defect in the notice to any Holder shall not impair or affect the validity of the notice to any other Holder.

SECTION 3.05. Deposit of Redemption Price. Prior to the redemption date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary of the Company is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest on all Securities to be redeemed on that date other than Securities or portions of Securities called for redemption which have been delivered by the Company to the Trustee for cancellation.

SECTION 3.06. Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate for the Holder (at the Company’s expense) a new Security equal in principal amount to the unredeemed portion of the Security surrendered. The Trustee will cancel and dispose of that Security surrendered for partial redemption and deliver a certificate of

such disposition to the Company unless the Company directs the Trustee to deliver canceled Securities to the Company.

SECTION 4.01. Payment of Securities. The Company shall promptly pay the principal of and interest on the Securities on the dates and in the manner provided in the Securities and in this Indenture. Principal and interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds in accordance with this Indenture (as of 12:00 p.m., New York City time, on the due date) money sufficient to pay all principal and interest then due.

The Company shall pay interest on overdue principal at the rate specified therefor in the Securities, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful.

SECTION 4.02. Reports. Whether or not the Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall file with the SEC and provide the Trustee and Holders with such annual and other reports as are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation subject to such Sections, such reports to be so filed and provided within the time periods specified for the filings of such reports under such Sections and containing all the information, audit reports and exhibits required for such reports. If, at any time, the Company is not subject to the periodic reporting requirements of the Exchange Act for any reason, the Company shall nevertheless continue filing the reports specified in the preceding sentence with the SEC within the time periods required unless the SEC will not accept such a filing. The availability of the foregoing reports on the SEC’s EDGAR service (or successor thereto) shall be deemed to satisfy the Company’s delivery obligations to the Trustee and the Holders. The Company agrees that it will not take any action for the purpose of causing the SEC not to accept such filings. If, notwithstanding the foregoing, the SEC will not accept such filings for any reason, the Company shall post the specified reports on its website within the time periods that would apply if the Company were required to file those reports with the SEC.

At any time that any of the Company’s Subsidiaries are Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraph shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial condition and results of operations of the Company and the Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

In addition, at any time when the Company is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall furnish to

the Holders and to prospective investors, upon the requests of such Holders, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Securities are not freely transferable under the Securities Act.

premium, if any, and interest payable on such Indebtedness, the amount of such Indebtedness expressed in U.S. dollars shall be as provided in such Currency Agreement. The principal amount of any Refinancing Indebtedness Incurred in the same currency as the Indebtedness being Refinanced shall be the U.S. Dollar Equivalent of the Indebtedness Refinanced, except to the extent that (1) such U.S. Dollar Equivalent was determined based on a Currency Agreement, in which case the Refinancing Indebtedness shall be determined in accordance with the preceding sentence and (2) the principal amount of the Refinancing Indebtedness exceeds the principal amount of the Indebtedness being Refinanced, in which case the U.S. Dollar Equivalent of such excess shall be determined on the date such Refinancing Indebtedness is Incurred.

SECTION 4.04. Limitation on Restricted Payments. (a) The Company shall not, and shall not permit any Restricted Subsidiary, directly or indirectly, to make a Restricted Payment if at the time the Company or such Restricted Subsidiary makes such Restricted Payment:

(1) a Default shall have occurred and be continuing (or would result therefrom);

(2) immediately after giving effect to such Restricted Payment on a pro forma basis, the Company would not be entitled to Incur an additional $1.00 of Coverage Indebtedness pursuant to Section 4.03(a); or

(C) the amount by which Indebtedness of the Company is reduced upon the conversion or exchange subsequent to January 1, 2011 of any Indebtedness of the Company convertible or exchangeable for Qualified Equity Interests of the Company (less the amount of any cash, or the Fair Market Value of any other property, distributed by the

Company upon such conversion or exchange); provided, however, that the foregoing amount shall not exceed the Net Cash Proceeds received by the Company or any Restricted Subsidiary from the sale of such Indebtedness (excluding Net Cash Proceeds from sales to a Subsidiary of the Company or to an employee stock ownership plan or a trust established by the Company or any of its Subsidiaries for the benefit of their employees); plus

(D) an amount equal to the sum of (x) the net reduction in the Investments (other than Permitted Investments) made by the Company or any Restricted Subsidiary in any Person resulting from repurchases, repayments or redemptions of such Investments by such Person, proceeds realized on the sale of such Investment and proceeds representing the return of capital (excluding dividends and distributions), in each case received by the Company or any Restricted Subsidiary, and (y) to the extent such Person is an Unrestricted Subsidiary, the portion (proportionate to the Company’s equity interest in such Subsidiary) of the Fair Market Value of the net assets of such Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary; provided, however, that the foregoing sum shall not exceed, in the case of any such Person or Unrestricted Subsidiary, the amount of Investments (excluding Permitted Investments) previously made (and treated as a Restricted Payment) by the Company or any Restricted Subsidiary in such Person or Unrestricted Subsidiary.

(1) any Restricted Payment made out of the Net Cash Proceeds of the substantially concurrent sale of, or made by exchange for, Qualified Equity Interests of the Company or a substantially concurrent cash capital contribution received by the Company from its stockholders; provided, however, that the Net Cash Proceeds from such sale or such cash capital contribution (to the extent so used for such Restricted Payment) shall be excluded from the calculation of amounts under Section 4.04(a)(3)(B);

(2) any purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of Subordinated Obligations of the Company or a Subsidiary Guarantor made by exchange for, or out of the proceeds of the substantially concurrent Incurrence of, Indebtedness of such Person which is permitted to be Incurred pursuant to Section 4.03;

(3) the payment of any dividend or redemption of any Capital Stock or Subordinated Obligations within 60 days after the date of declaration thereof or call for redemption, if at such date of declaration or call for redemption such payment or redemption was permitted by the provisions of Section 4.04(a) (the declaration of such payment shall be deemed a Restricted Payment under Section

4.04(a) as of the date of declaration, and the payment itself shall be deemed to have been paid on such date of declaration and will not also be deemed a Restricted Payment under Section 4.04(a)) (it being understood that any Restricted Payment made in reliance on this clause (3) shall reduce the amount available for Restricted Payments pursuant to Section 4.04(a)(3) only once);

(6) cash payments in lieu of the issuance of fractional shares in connection with the exercise of warrants, options or other securities convertible into or exchangeable for Equity Interests of the Company; provided, however, that any such cash payment shall not be for the purpose of evading the limitation of this Section 4.04 (as determined in good faith by the Board of Directors of the Company);

(7) in the event of a Change of Control or an Asset Disposition, and if no Default shall have occurred and be continuing, the payment, purchase, redemption, defeasance or other acquisition or retirement of Subordinated Obligations of the Company or any Subsidiary Guarantor, in each case, at a purchase price not greater than 101% of the principal amount of such Subordinated Obligations in the case of a Change of Control and 100% in the case of an Asset Disposition, in each case plus any accrued and unpaid interest thereon; provided, however, that prior to such payment, purchase, redemption, defeasance or other acquisition or retirement, the Company (or a third party to the extent permitted by this Indenture) has made a Change of Control Offer or an offer to purchase Securities pursuant to Section 4.06, as applicable, with respect to the Securities as a result of such Change of Control or Asset Disposition, as applicable, and has repurchased all Securities validly tendered and not withdrawn in connection with such Change of Control Offer or an offer to purchase Securities pursuant to Section 4.06;

SECTION 4.05. Limitation on Restrictions on Distributions from Restricted Subsidiaries. The Company shall not, and shall not permit any Restricted Subsidiary to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to (a) (i) pay dividends or make any other distributions to the Company or any of the Restricted Subsidiaries on its Capital Stock or with respect to any other interest or participation in, or measured by, its profits or (ii) pay any Indebtedness owed to the Company, (b) make any loans or advances to the Company or (c) sell, lease or transfer any of its properties or assets to the Company, except:

refunding, replacement or Refinancing to an agreement referred to in Section 4.05(1)(A) or (B) or this clause (C); provided, however, that the encumbrances and restrictions with respect to such Restricted Subsidiary contained in any such refinancing agreement or amendment are, as determined by an Officer in good faith, not materially less favorable to the Holders than encumbrances and restrictions with respect to such Restricted Subsidiary contained in such predecessor agreements; and

(D) any encumbrance or restriction with respect to a Restricted Subsidiary imposed pursuant to an agreement entered into for the sale or disposition of all or substantially all the Equity Interests or assets of such Restricted Subsidiary pending the closing of such sale or disposition;

SECTION 4.06. Limitation on Sales of Assets and Subsidiary Stock. (a) The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Disposition unless:

(1) the Company or such Restricted Subsidiary receives consideration at the time of such Asset Disposition at least equal to the Fair Market Value (including as to the value of all non-cash consideration), of the shares and assets subject to such Asset Disposition;

(2) at least 75% of the consideration thereof received by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents;

(3) in the case of an Asset Disposition of Collateral, the consideration from such Asset Disposition is pledged as Collateral to secure the Securities; and

(4) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company (or such Restricted Subsidiary, as the case may be) at its option to any one or more of the following uses:

(A) to the extent the Company elects, within 365 days after the receipt of Net Available Cash,

(B) to the extent the Company elects, to acquire Additional Assets within 365 days of the receipt of such Net Available Cash; provided, however, that to the extent the assets subject to such Asset Disposition were Collateral, such newly acquired assets shall also be Collateral; and

(C) to the extent the Company elects, to make an offer to the Holders (and to holders of other Applicable Senior Indebtedness of the Company or of a Subsidiary Guarantor designated by the Company) to purchase Securities (and such other Applicable Senior Indebtedness of the Company or a Subsidiary Guarantor) pursuant to and subject to the conditions contained in this Indenture.

Notwithstanding the foregoing provisions of this Section 4.06(a), the Company and the Restricted Subsidiaries shall not be required to apply any Net Available Cash in accordance with this Section 4.06(a) except to the extent that the aggregate Net Available Cash from all Asset Dispositions which is not applied in accordance with this Section 4.06(a) exceeds $10,000,000. Pending application of Net Available Cash pursuant to this Section 4.06(a), such Net Available Cash shall be held in cash or invested in Cash Equivalents.

For the purposes of this Section 4.06(a), the following are deemed to be cash or Cash Equivalents:

(1) the assumption or discharge of Applicable Senior Indebtedness of the Company (other than obligations in respect of Disqualified Stock of the

Company) or any Restricted Subsidiary (other than obligations in respect of Disqualified Stock or Preferred Stock of a Subsidiary Guarantor) and the release of the Company or such Restricted Subsidiary from all liability on such Applicable Senior Indebtedness in connection with such Asset Disposition;

(2) securities, notes or other obligations received by the Company or any Restricted Subsidiary from the transferee that are converted by the Company or such Restricted Subsidiary into cash within 365 days of the consummation of the Asset Disposition, to the extent of the cash received in such conversion; and

(3) any Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Disposition having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (3) that is at that time outstanding, not to exceed an amount equal to $20,000,000 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).

(b) In the event of an Asset Disposition that results in the purchase of Securities (and other Applicable Senior Indebtedness of the Company or of a Subsidiary Guarantor) pursuant to Section 4.06(a)(4)(C), the Company shall purchase Securities tendered pursuant to an offer by the Company for the Securities (and such other Applicable Senior Indebtedness of the Company or of a Subsidiary Guarantor permitted to be included in such offer) at a purchase price of 100% of their principal amount (or, in the event such other Applicable Senior Indebtedness was issued with significant original issue discount, 100% of the accreted value thereof), without premium, plus accrued but unpaid interest (or, in respect of such other Applicable Senior Indebtedness, such lesser price, if any, as may be provided for by the terms of such other Applicable Senior Indebtedness) in accordance with the procedures (including prorating in the event of oversubscription) set forth in this Indenture. If the aggregate purchase price of the securities tendered exceeds the Net Available Cash allotted to their purchase, the Company shall select the securities to be purchased on a pro rata basis but in round denominations, which in the case of the Securities will be minimum denominations of $2,000 principal amount or any greater integral multiple of $1,000. The Company shall not be required to make such an offer to purchase Securities (and other Applicable Senior Indebtedness of the Company or of a Subsidiary Guarantor) pursuant to this Section 4.06 if the Net Available Cash available therefor is less than $20,000,000 (which lesser amount shall be carried forward for purposes of determining whether such an offer is required with respect to the Net Available Cash from any subsequent Asset Disposition). Upon completion of such an offer to purchase, Net Available Cash shall be deemed to be reduced by the aggregate amount of such offer.

(c) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this Section 4.06. To the extent that the provisions of any securities laws or regulations conflict with

provisions of this Section 4.06, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.06 by virtue of its compliance with such securities laws or regulations.

SECTION 4.07. Limitation on Affiliate Transactions. (a) The Company shall not, and shall not permit any Restricted Subsidiary to, enter into or permit to exist any transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements or the rendering of any service) with, or for the benefit of, any Affiliate of the Company (an “Affiliate Transaction”) unless:

(1) the terms of the Affiliate Transaction are no less favorable to the Company or such Restricted Subsidiary than those that could be obtained at the time of the Affiliate Transaction in arm’s-length dealings with a Person who is not an Affiliate;

(2) if such Affiliate Transaction involves an amount in excess of $10,000,000, the terms of the Affiliate Transaction are set forth in writing and a majority of the non-employee directors of the Company disinterested with respect to such Affiliate Transaction have determined in good faith that the criteria set forth in Section 4.07(a)(1) are satisfied and have approved the relevant Affiliate Transaction as evidenced by a resolution of the Board of Directors of the Company (unless the Board of Directors of the Company at the time of such Affiliate Transaction has no non-employee directors of the Company disinterested with respect to such Affiliate Transaction, in which case clause (3) below will apply to such Affiliate Transaction); and

(3) if such Affiliate Transaction involves an amount in excess of $15,000,000 (or if such Affiliate Transaction involves an amount in excess of $10,000,000 and the Board of Directors of the Company at the time of such Affiliate Transaction has no non-employee directors of the Company disinterested with respect to such Affiliate Transaction), the Board of Directors of the Company shall have received a written opinion from an Independent Qualified Party to the effect that such Affiliate Transaction is fair, from a financial standpoint, to the Company and the Restricted Subsidiaries or is not materially less favorable to the Company and the Restricted Subsidiaries than could reasonably be expected to be obtained at the time in an arm’s-length transaction with a Person who was not an Affiliate.

(1) any Investment (other than a Permitted Investment) or other Restricted Payment, in each case permitted to be made pursuant to Section 4.04;

(2) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements, stock options and stock ownership plans approved by the Board of Directors of the Company;

(3) loans or advances to employees made in the ordinary course of business for bona fide business purposes and consistent with past practices of the Company or the Restricted Subsidiaries;

(4) the payment of reasonable fees to directors of the Company and the Restricted Subsidiaries who are not employees of the Company or the Restricted Subsidiaries;

(5) any transaction with the Company, a Restricted Subsidiary or joint venture or similar entity which would constitute an Affiliate Transaction solely because the Company or a Restricted Subsidiary owns an equity interest in or otherwise controls such Restricted Subsidiary, joint venture or similar entity;

(7) any agreement as in effect on the Issue Date and described in the Offering Circular or any renewals or extensions of any such agreement (so long as such renewals or extensions are not less favorable to the Company or the Restricted Subsidiaries) and the transactions evidenced thereby; and

(8) entering into and performing under indemnification arrangements or agreements in the ordinary course of business for the benefit of former, current or future directors or officers of the Company or any or its Restricted Subsidiaries.

SECTION 4.08. Limitation on Line of Business. The Company shall not, and shall not permit any Restricted Subsidiary, to engage in any business other than a Related Business.

SECTION 4.09. Change of Control. (a) Upon the occurrence of a Change of Control, each Holder shall have the right to require that the Company repurchase such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

(b) Subject to compliance with the provisions of Section 4.09(c), within 30 days following any Change of Control, the Company shall mail a notice to each Holder with a copy to the Trustee (the “Change of Control Offer”) stating:

(1) that a Change of Control has occurred and that such Holder has the right to require the Company to purchase such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest on the relevant interest payment date);

(2) the circumstances and relevant facts regarding such Change of Control (including information to the extent available, with respect to pro forma historical income, cash flow and capitalization, in each case after giving effect to such Change of Control);

(3) the purchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed); and

(4) the instructions, as determined by the Company, consistent with this Section, that a Holder must follow in order to have its Securities purchased.

(c) The Company shall not be required to make a Change of Control Offer following a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Securities validly tendered and not withdrawn under such Change of Control Offer, (2) notice of redemption has been given pursuant to this Indenture as described above in Section 3.01, unless and until there is a default in the payment of the applicable redemption price or (3) in connection with or in contemplation of any Change of Control for which a definitive agreement is in place, the Company or a third party has made an offer to purchase (an “Alternate Offer”) any and all Securities validly and properly tendered at a cash price equal to or higher than the Change of Control payment (as described above) and has purchased all Securities validly and properly tendered and not withdrawn in accordance with the terms of the Alternate Offer; provided, however, that the terms of such Alternate Offer shall not require the Holders to irrevocably tender the Securities and such Alternate Offer shall not close until the Change of Control is actually consummated.

(d) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.09, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.09 by virtue of its compliance with such securities laws or regulations.

SECTION 4.10. Limitation on Liens. The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, Incur or suffer to exist or become effective any Lien of any kind upon any of their assets, now owned or hereafter acquired, other than:

(i) in the case of any asset that does not constitute Collateral, Permitted Liens; provided, however, that any Lien on such asset shall be permitted notwithstanding that it is not a Permitted Lien if all payments due under this Indenture and the Securities are secured on an equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien; and

(ii) in the case of any asset that constitutes Collateral, Permitted Collateral Liens.

In the case of the clause (i) above, if the obligations so secured are expressly subordinated by their terms to the Securities, the Lien securing such obligations shall also be so subordinated by its terms at least to the same extent.

SECTION 4.11. Limitation on Sale/Leaseback Transactions. (a) The Company shall not, and shall not permit any Restricted Subsidiary to, enter into any Sale/Leaseback Transaction with respect to any property unless:

SECTION 4.13. Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company an Officers’ Certificate stating whether or not to the best of the knowledge of the signers thereof a Default occurred during such period. If a Default shall have occurred during such period, the certificate shall describe the Default, its status and what action the

Company is taking or proposes to take with respect thereto. The Company also shall comply with TIA § 314(a)(4).

SECTION 5.01. When Company May Merge or Transfer Assets. (a) The Company shall not consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a series of transactions, directly or indirectly, all or substantially all its assets to, any Person, unless:

(2) immediately after giving pro forma effect to such transaction (and treating any Indebtedness which becomes an Obligation of the Successor Company or any Subsidiary as a result of such transaction as having been Incurred by such Successor Company or such Subsidiary at the time of such transaction), no Default shall have occurred and be continuing;

(3) immediately after giving pro forma effect to such transaction, the Successor Company would have been able to Incur an additional $1.00 of Coverage Indebtedness pursuant to Section 4.03(a); and

(4) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with this Indenture;

provided, however, that clause (3) shall not be applicable to (A) a Restricted Subsidiary consolidating with, merging into or transferring all or part of its properties and assets to the Company or (B) the Company merging with an Affiliate of the Company solely for the purpose and with the sole effect of reincorporating the Company in another jurisdiction.

For purposes of this Section 5.01, the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

The Successor Company (if not the Company) shall be the successor to the Company and shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture, and the predecessor Company, except in the case of a lease, shall be released from the obligation to pay the principal of and interest on the Securities.

(b) The Company shall not permit any Subsidiary Guarantor to consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a series of transactions, all or substantially all of its assets to any Person unless immediately after giving effect to such transaction or transactions on a pro forma basis (and treating any Indebtedness which becomes an obligation of the resulting, surviving or transferee Person as a result of such transaction as having been issued by such Person at the time of such transaction), no Default shall have occurred and be continuing.

(1) the Company defaults in the payment of interest on the Securities when due, continued for 30 days;

(2) the Company defaults in the payment of principal of any Security when due at its Stated Maturity, upon optional redemption in accordance with Article 3, upon required purchase, upon declaration of acceleration or otherwise;

(3) the failure by the Company to comply with its obligations under Section 5.01;

(4) the failure by the Company or any Subsidiary Guarantor to comply for 60 days after notice with any with its other agreements contained in the Securities or this Indenture;

(5) Indebtedness of the Company or any Restricted Subsidiary is not paid within any applicable grace period after final maturity or is accelerated by the holders thereof because of a default and the total amount of such Indebtedness unpaid or accelerated exceeds $20,000,000;

(6) the Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(B) consents to the entry of an order for relief against it in an involuntary case;

(7) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(A) is for relief against the Company or any Significant Subsidiary in an involuntary case;

(B) appoints a Custodian of the Company or any Significant Subsidiary or for any substantial part of its property; or

or any similar relief is granted under any foreign laws and the order or decree remains unstayed and in effect for 60 consecutive days;

(8) any judgment or decree for the payment of money in excess of $20,000,000 is entered against the Company or any Significant Subsidiary, remains outstanding for a period of 60 consecutive days following such judgment and is not discharged, waived or stayed;

(9) any Subsidiary Guarantee ceases to be in full force and effect (other than in accordance with the terms of such Subsidiary Guarantee) or any Subsidiary Guarantor denies or disaffirms its obligations under its Subsidiary Guarantee; or

(10)(1) a default by the Company or any Subsidiary Guarantor in the performance of the Security Documents which adversely affects the enforceability, validity, perfection or priority of the Second Priority Collateral Agent’s Lien on the Collateral in any material respect; (2) repudiation or disaffirmation by the Company or any Subsidiary Guarantor of any of its material obligations under the Security Documents; or (3) the determination in a judicial proceeding that any one or more material provisions of the Security Documents are unenforceable or invalid against the Company or any Subsidiary Guarantor for any reason except to the extent any such unenforceability or invalidity is caused by the failure of the Second Priority Collateral Agent to make filings, renewals and continuations (or other equivalent filings) which the Company has indicated in the perfection certificate are required to be made or the failure of the Second Priority Collateral Agent to maintain possession of certificates actually delivered to such agent representing securities pledged under the Security Documents.

The foregoing will 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 Federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

A Default under clause (4) will 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 Company of the Default and the Company does not cure such Default within the time specified after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default”.

If a Default occurs, is continuing and is known to the Trustee, the Trustee must mail to each Holder of the Securities notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of or interest on any Security, the Trustee may withhold notice if and so long as a committee of its Trust Officers in good faith determines that withholding notice is not opposed to the interest of the Holders. In addition, the Company is required to deliver to the Trustee, within 120 days after the end of each fiscal year, a certificate indicating whether the signers thereof know of any Default that occurred during the previous year. The Company is required to deliver to the Trustee, within 30 days after the occurrence thereof, written notice of any event which would constitute certain Defaults, their status and what action the Company 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(6) or (7) with respect to the Company) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the Securities by notice to the Company and the Trustee, may declare the principal of and accrued but unpaid interest on all the Securities to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified in Section 6.01(6) or (7) with respect to the Company occurs and is continuing, the principal of and interest on all the Securities 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. In the event of an acceleration that occurs prior to March 15, 2015, an amount will also become due and payable as of the day immediately preceding the day that the Securities were accelerated equal to the premium that would then be payable by the Company if the Company elected to redeem the Securities at its option on such date pursuant to the provisions described in Section 6 of the Securities. 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 have been cured or waived except nonpayment of principal or interest that has become due solely

because of such declaration of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of or interest on the Securities 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. All available remedies are cumulative.

SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in principal amount of the Securities by 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 (b) a Default arising from the failure to redeem or purchase any Security when required pursuant to 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, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

SECTION 6.05. Control by Majority. The Holders of a majority in principal amount of the 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 other Holders or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, 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. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder may pursue any remedy with respect to this Indenture or the Securities unless:

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

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

(3) such Holder or Holders offer to the Trustee reasonable security or indemnity against any loss, liability or expense;

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

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

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

SECTION 6.07. Rights of Holders to Receive Payment. 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, on or after the respective due dates expressed 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(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07.

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 and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property 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 Person performing similar functions, 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 the Trustee 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 7.07.

SECTION 6.10. Priorities. If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

FIRST: to the Trustee for amounts due under Section 7.07 and to the Second Priority Collateral Agent for amounts due under the Collateral Agreement;

SECOND: to Holders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. At least 15 days before such record date, the Company or Trustee, at the request of the Company delivered at least three business days before the date such notice is to be given, shall mail to each Holder a notice that states the record date, the payment date and amount to be paid.

SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court of competent jurisdiction in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 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 aggregate principal amount of the Securities.

SECTION 6.12. Waiver of Stay or Extension Laws. The Company (to the extent it may lawfully do so) shall not 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, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives 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.

SECTION 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

(1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall

examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own wilful misconduct, except that:

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer unless the Trustee was negligent in ascertaining the pertinent facts; and

(3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05.

(i) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01.

(ii) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company.

(iii) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(iv) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(v) Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section and to the provisions of the TIA.

SECTION 7.02. Rights of Trustee. (a) The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel.

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

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers; provided, however, that the Trustee’s conduct does not constitute wilful misconduct or negligence.

(e) The Trustee may consult with counsel, and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Securities shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

(f) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficiently evidenced by a written order signed by one Officer of the Company.

(g) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the corporate trust office of the Trustee, and such notice references the Securities and this Indenture.

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities (including that of Second Priority Collateral Agent) hereunder (and under the Security Documents and any Intercreditor Agreement), and each agent, custodian and other Person employed to act hereunder or thereunder.

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

(j) The Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

(k) In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

SECTION 7.04. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than any Trustee’s certificate of authentication.

SECTION 7.05. Notice of Defaults. If a Default occurs, is continuing and is known to the Trustee, the Trustee shall mail to each Holder notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of or interest on any Security (including payments pursuant to the mandatory redemption provisions of such Security, if any), the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is not opposed to the interests of the Holders.

SECTION 7.06. Reports by Trustee to Holders. As promptly as practicable after each October 1 beginning with the October 1 following the Issue Date, and in any event prior to December 1 in each year, the Trustee shall mail to each Holder a brief report dated as of October 1 that complies with TIA § 313(a). The Trustee also shall comply with TIA § 313(b).

A copy of each report at the time of its mailing to Holders shall be filed with the SEC and each stock exchange (if any) on which the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof.

As promptly as practicable, upon the Company’s request, the Trustee shall mail to each Securityholder any report received by the Trustee from the Company pursuant to Section 4.02.

SECTION 7.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time such compensation for its services as shall be agreed to from time to time between the Trustee and the Company. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company and the Subsidiary Guarantors shall jointly and severally indemnify the Trustee against any and all loss, liability or expense (including attorneys’

fees) incurred by it in connection with the administration of this trust and the performance of its duties hereunder. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own wilful misconduct, negligence or bad faith.

To secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities.

The Company’s payment obligations pursuant to this Section shall survive the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(7) or (8) with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

SECTION 7.08. Replacement of Trustee. The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if:

(3) a receiver or other public officer takes charge of the Trustee or its property; or

If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount of the Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07.

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have.

SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA § 310(b); provided, however, that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA § 310(b)(1) are met. The Trustee shall be permitted to engage in other transactions; provided, however, if it acquires any conflicting interest it must either eliminate such conflict within 90 days, apply to the SEC for permission to continue or resign

SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated.

SECTION 7.12. Limitation on Duty of Trustee in Respect of Collateral; Indemnification.

(a) Beyond the exercise of reasonable care in the custody thereof, the Trustee, in its capacity as trustee, shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Trustee, in its capacity as trustee, shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. The Trustee, in its capacity as trustee, shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Trustee, in its capacity as trustee, in good faith.

(b) The Trustee, in its capacity as trustee, shall not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence, bad faith or willful misconduct on the part of the Trustee, in its capacity as trustee, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of the Company to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Trustee, in its capacity as trustee, shall have no duty to ascertain or inquire as to the performance or observance of any of the terms of this Indenture, the Collateral Agency Agreement or the Security Documents by the Company or the Second Priority Collateral Agent.

SECTION 8.01. Discharge of Liability on Securities; Defeasance. (a) When (1) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.07) for cancellation or (2) all outstanding Securities have become due and payable, whether at maturity or on a redemption date as a result of the mailing of a notice of redemption pursuant to Article 3 hereof and the Company irrevocably deposits or causes to be deposited with the Trustee as trust funds in trust solely for the benefit of the Securityholders, cash in U.S. dollars, U.S. Government Obligations, or a combination thereof, in amounts as will be sufficient, without consideration of any reinvestment of interest to pay and discharge the entire Indebtedness on the Securities not previously delivered to the Trustee for cancellation (other than Securities replaced pursuant to Section 2.07) (including principal of, premium and interest, if any, on, the Securities to the date of maturity or redemption), and if in either

case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 8.01(c), cease to be of further effect. The Trustee shall acknowledge satisfaction and discharge of this Indenture by means of an acknowledgment upon request by the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company.

(b) Subject to Sections 8.01(c) and 8.02, the Company at any time may terminate (1) all of the Company’s and each Subsidiary Guarantor’s obligations under the Securities, the Subsidiary Guarantees and this Indenture (“legal defeasance option”) or (2) their obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11 and 4.12 and the operation of Sections 6.01(4), 6.01(5), 6.01(6), 6.01(7), 6.01(8) and 6.01(10) (but, in the case of Sections 6.01(6) and (7), with respect only to Significant Subsidiaries) and the limitations contained in Section 5.01(a)(3) (“covenant defeasance option”). The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.

If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default with respect thereto. If the Company exercises its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in Sections 6.01(4), 6.01(5), 6.01(6), 6.01(7), 6.01(8) or 6.01(10) (but, in the case of Sections 6.01(6) and (7), with respect only to Significant Subsidiaries) or because of the failure of the Company to comply with Section 5.01(a)(3). If the Company exercises its legal defeasance option or its covenant defeasance option, each Subsidiary Guarantor, if any, shall be released from all its obligations with respect to its Subsidiary Guarantee and the Security Documents.

Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates.

(c) Notwithstanding clauses (a) and (b) above, the Company’s obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08 and in this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections 7.07, 8.04 and 8.05 shall survive.

SECTION 8.02. Conditions to Defeasance. The Company may exercise its legal defeasance option or its covenant defeasance option only if:

(1) the Company irrevocably deposits in trust with the Trustee money or U.S. Government Obligations for the payment of principal of and interest on the Securities to maturity or redemption, as the case may be;

(2) the Company delivers to the Trustee a certificate from a nationally recognized investment bank, appraisal firm or independent public accounting firm expressing their opinion that the payments of principal and interest when due, plus any deposited money will provide cash at such times and in such amounts as

will be sufficient to pay principal and interest when due on all the Securities to maturity or redemption, as the case may be;

(3) the Company delivers to the Trustee an Opinion of Counsel (which opinion may be subject to customary assumptions and exceptions) to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally;

(4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings);

(5) the deposit does not constitute a default under any other material agreement (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) binding on the Company;

(6) the Company delivers to the Trustee an Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute, nor is qualified as, a regulated investment company under the Investment Company Act of 1940;

(7) in the case of the legal defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (B) since the Issue Date there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred;

(8) in the case of the covenant defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; and

(9) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities as contemplated by this Article 8 have been complied with.

Before or after a deposit, the Company may make arrangements satisfactory to the Trustee for the redemption of Securities at a future date in accordance with Article 3.

SECTION 8.03. Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities.

SECTION 8.04. Repayment to Company. The Trustee and the Paying Agent shall promptly turn over to the Company upon request any excess money or securities held by them at any time.

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Company for payment as general creditors.

SECTION 8.05. Indemnity for Government Obligations. The Company shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations.

SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court of competent jurisdiction or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and each Subsidiary Guarantor’s obligations under this Indenture, each Subsidiary Guarantee and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8; provided, however, that, if the Company has made any payment of interest on or principal of any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

SECTION 9.01. Without Consent of Holders. The Company, the Subsidiary Guarantors and the Trustee may amend this Indenture, the Securities, the Security Documents or any Intercreditor Agreement without notice to or consent of any Holder:

(2) to provide for the assumption by a successor corporation of the obligations of the Company or any Subsidiary Guarantor under the Securities, this Indenture, a Subsidiary Guarantee, the Security Documents or any Intercreditor Agreement, as applicable;

(3) to provide for uncertificated Securities in addition to or in place of certificated Securities; provided, however, that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code;

(4) to add Guarantees with respect to the Securities, including any Subsidiary Guarantees;

(5) to add to the covenants of the Company or any Subsidiary Guarantor for the benefit of the Holders or to surrender any right or power herein conferred upon the Company or any Subsidiary Guarantor;

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

(7) to comply with any requirement of the SEC in connection with the qualification of this Indenture under the TIA;

(8) to conform the text of this Indenture, the Securities and the Subsidiary Guarantees to any provision of the “Description of the Notes” contained in the Offering Circular to the extent that such provision in the “Description of the Notes” was intended to be a verbatim recitation of a provision of this Indenture, the Securities and the Subsidiary Guarantees;

(9) to make any amendment to the provisions of this Indenture relating to the transfer and legending of Securities; provided, however, that (a) compliance with this Indenture as so amended would not result in Securities being transferred in violation of the Securities Act or any other applicable securities law and (b) such amendment does not materially and adversely affect the rights of Holders to transfer Securities, in each case evidenced by an Opinion of Counsel on which the Trustee may conclusively rely;

(11) to release Collateral from the Lien of the Security Documents when permitted or required by this Indenture and the Security Documents;

(12) to provide for a successor trustee in accordance with the terms of this Indenture or to otherwise comply with any requirement of this Indenture; or

After an amendment under this Section 9.01 becomes effective, the Company shall mail to Holders a notice briefly describing such amendment. However, 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 9.01.

SECTION 9.02. With Consent of Holders. The Company, the Subsidiary Guarantors and the Trustee may amend this Indenture, the Securities, the Security Documents or any Intercreditor Agreement with the written consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including consents obtained in connection with a tender offer or exchange for the Securities) and any past default or compliance with any provisions may also be waived with the consent of the Holders of at least a majority in principal amount of the Securities then outstanding. However, without the consent of each Holder affected thereby, an amendment or waiver may not:

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

(4) change the provisions applicable to the redemption of any Security contained in Article 3 hereto or Section 6 of the Securities;

(6) impair the right of any Holder to receive payment of principal of and interest on such Holder’s Securities on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Securities;

(7) make any change in the amendment provisions that require each Holder’s consent or in the waiver provisions;

(8) make any change in the ranking or priority of any Security that would materially adversely affect the Holders;

(9) release any Subsidiary Guarantee (other than in accordance with this Indenture); or

(10)(A) modify any Security Document or any Intercreditor Agreement or the provisions in this Indenture dealing with Security Documents in any manner that adversely changes the priority of the Liens in the Collateral or (B) release all or substantially all of the Collateral from the Liens created by the

Security Documents, except in each case as specifically provided for in this Indenture, the Security Documents and any Intercreditor Agreement.

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, but it shall be sufficient if such consent approves the substance thereof.

After an amendment under this Section 9.02 becomes effective, the Company shall mail to Holders a 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. Compliance with the Trust Indenture Act. Every amendment to this Indenture or the Securities shall comply with the TIA as then in effect.

SECTION 9.04. Revocation and Effect of Consents and Waivers. A consent to an amendment 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 or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective upon the execution of such amendment or waiver by the Trustee.

The Company 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 the immediately preceding paragraph, 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 9.05. Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Trustee 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 Company or the Trustee so determines, the Company 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.

SECTION 9.06. Trustee to Sign Amendments. The Trustee shall sign any amendment 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 reasonably satisfactory to it and to receive, and (subject to Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture.

SECTION 9.07. Payment for Consent. Neither the Company nor any Affiliate of the Company 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 all Holders and is 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 10.01. Guarantees. Each Subsidiary Guarantor hereby unconditionally and irrevocably guarantees, jointly and severally on a senior secured basis, to each Holder and to the Trustee and its successors and assigns (a) the full and punctual payment of principal of and interest on the Securities when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Indenture and the Securities and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture and the Securities (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Subsidiary Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Subsidiary Guarantor and that such Subsidiary Guarantor will remain bound under this Article 10 notwithstanding any extension or renewal of any Obligation.

Each Subsidiary Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (1) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person (including any Subsidiary Guarantor) under this Indenture, the Securities or any other agreement or otherwise; (2) any extension or renewal of any thereof; (3) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (4) the release of any security held by any Holder or the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (6) except as set forth in Section 10.06, any change in the ownership of such Subsidiary Guarantor.

Each Subsidiary Guarantor further agrees that its Subsidiary 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 or the Trustee to any security held for payment of the Guaranteed Obligations.

Except as expressly set forth in Sections 8.01(b), 10.02 and 10.06, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim 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 Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity.

Each Subsidiary 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 Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Obligation, each Subsidiary Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (A) the unpaid amount of such Guaranteed Obligations, (B) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and (C) all other monetary Guaranteed Obligations of the Company to the Holders and the Trustee.

Each Subsidiary Guarantor agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations hereby may be accelerated as provided in Article 6 for the purposes of such Subsidiary Guarantor’s Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether

or not due and payable) shall forthwith become due and payable by such Subsidiary Guarantor for the purposes of this Section 10.01.

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

SECTION 10.02. Limitation on Liability. Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

SECTION 10.03. Successors and Assigns. This Article 10 shall be binding upon each Subsidiary Guarantor and its successors and assigns and shall enure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder 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 10.04. No Waiver. Neither a failure nor a delay on the part of either the Trustee 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. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 10 at law, in equity, by statute or otherwise.

SECTION 10.05. Modification. No modification, amendment or waiver of any provision of this Article 10, nor the consent to any departure by any Subsidiary 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 Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 10.06. Release of Subsidiary Guarantor. A Subsidiary Guarantor will be released from its obligations under this Article 10 (other than any obligation that may have arisen under Section 10.07).

(1) upon the sale (including any sale pursuant to any exercise of remedies by a holder of Indebtedness of the Company or of such Subsidiary Guarantor) or other disposition (including by way of consolidation or merger) of a Subsidiary Guarantor (including the sale or disposition of Equity Interests of a

Subsidiary Guarantor) following which such Subsidiary Guarantor is no longer a Subsidiary of the Company;

(2) upon the sale or disposition of all or substantially all the assets of a Subsidiary Guarantor;

(3) upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary to the extent permitted by this Indenture;

(5) upon the full satisfaction of the Company’s obligations under this Indenture;

provided, however, that in the case of clauses (1) and (2) above, (i) such sale or other disposition is made to a Person other than the Company or a Subsidiary of the Company, (ii) such sale or disposition is otherwise permitted by this Indenture and (iii) the Company provides an Officers’ Certificate to the Trustee to the effect that the Company will comply with its obligations under Section 4.06.

At the request of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing such release.

SECTION 10.07. Contribution. Each Subsidiary Guarantor that makes a payment under its Subsidiary Guarantee shall be entitled upon payment in full of all Guaranteed Obligations under this Indenture to a contribution from each other Subsidiary Guarantor in an amount equal to such other Subsidiary Guarantor’s pro rata portion of such payment based on the respective net assets of all the Subsidiary Guarantors at the time of such payment determined in accordance with GAAP.

SECTION 11.01. Collateral and Security Documents. (a) To secure the due and punctual payment of the obligations of the Company and the Subsidiary Guarantors under this Indenture, the Securities and the Subsidiary Guarantees, the Company, the Subsidiary Guarantors and the Second Priority Collateral Agent have entered into the Security Documents for the creation of specified security interests and related matters. The Trustee, the Company and the Subsidiary Guarantors hereby acknowledge and agree that the Second Priority Collateral Agent holds the Collateral in trust for the equal and ratable benefit of the Holders and the Trustee and the other parties entitled to the benefit of the security provided under the Security Documents pursuant to the terms of the Security Documents and any Intercreditor Agreements. Notwithstanding anything to the contrary in this Indenture, no security interest or Lien is granted by the terms of this Indenture, the Securities or the Subsidiary Guarantees.

(b) Each Holder, by accepting a Security, agrees to all of the terms and provisions of the Security Documents and any Intercreditor Agreements, as the same may be amended from time to time pursuant to the provisions of the Security Documents, any Intercreditor Agreements and this Indenture, and authorizes and directs the Trustee and the Second Priority Collateral Agent to perform their respective obligations and exercise their respective rights under the Security Documents and any Intercreditor Agreements in accordance therewith; provided, however, that if any provisions of the Security Documents limit, qualify or conflict with the duties imposed by the provisions of the TIA (other than TIA §314(b) and TIA §314(d), which shall not be applicable to this Indenture unless it is qualified under the TIA), the TIA (other than TIA § 314(b) and TIA § 314(d), which shall not be applicable to this Indenture unless it is qualified under the TIA) will control.

(c) Each Holder, by accepting a Security, irrevocably appoints the Second Priority Collateral Agent to act as its agent under the Security Documents and irrevocably authorizes the Second Priority Collateral Agent to (i) perform the duties and exercise the rights, powers and discretions that are specifically given to it under the Security Documents, together with any other incidental rights, powers and discretions and (ii) execute each document expressed to be executed by the Second Priority Collateral Agent on its behalf.

(d) As among the Holders, the Collateral shall be held for the equal and ratable benefit of the Holders without preference, priority or distinction of any thereof over any other.

SECTION 11.02. Release of Collateral. (a) Collateral may be released from the security interest created by the Security Documents at any time or from time to time in accordance with the provisions of the Security Documents. 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 Lien on the Collateral in contravention of the provisions hereof if and to the extent the Collateral or Liens are released pursuant to the applicable Security Documents and pursuant to the terms of this Article 11. The Trustee and each of the Holders acknowledge that a release of Collateral or a Lien strictly in accordance with the terms of the Security Documents and of this Article 11 will not be deemed for any purpose to be an impairment of the Lien on the Collateral in contravention of the terms of this Indenture.

(b) The Liens created by the Security Documents on the Collateral shall be automatically released, without the need for any further action by any Person, and will no longer secure the Securities or the Subsidiary Guarantees or any other Obligations under this Indenture, and the right of the Holders and holders of such other Obligations to the benefits and proceeds of such Liens will terminate and be discharged:

(1) in whole, upon payment in full of the principal of, accrued and unpaid interest, if any, and premium, if any, on, the Securities;

(2) in whole, upon satisfaction and discharge of the Company’s obligations under this Indenture in accordance with Article 8;

(3) in whole, upon a legal defeasance or covenant defeasance as described in accordance with Article 8;

(4) in part, as to any property or asset constituting Collateral (A) as required by the First Lien-Second Lien Intercreditor Agreement, (B) that is sold or otherwise disposed of or deemed disposed of in a transaction permitted by Section 4.06, (C) that is owned by a Subsidiary Guarantor to the extent such Subsidiary Guarantor has been released from its Subsidiary Guarantee in accordance with Article 10 or (D) otherwise in accordance with, and as expressly provided for under, this Indenture (including a release of Excluded Assets (as defined in the Collateral Agreement) in connection with an Incurrence of Permitted Indebtedness secured by a Permitted Lien or Permitted Collateral Lien); or

(5) pursuant to any amendment or supplement to this Indenture or to the Securities effected in accordance with Article 9.

(c) In addition, Collateral may be released from the Liens created by the Security Documents at any time or from time to time in accordance with the provisions of the Security Documents and any applicable Intercreditor Agreements. At the request of the Company (which request shall be accompanied by an Opinion of Counsel and an Officers’ Certificate stating that all conditions precedent in the Indenture, Security Documents and any Intercreditor Agreement to the release of such Collateral have been satisfied) for a confirmation, acknowledgement or other documentation reasonably requested by the Company to evidence the release of Liens or Collateral in accordance with this Section 11.02, at the Company’s and the Subsidiary Guarantors’ expense, the Trustee shall promptly deliver such confirmation, acknowledgement or other documentation so reasonably requested by the Company. The release of any Collateral from the Lien of the Security Documents or the release, in whole or in part, of the Liens created by the Security Documents, shall not be deemed to impair the Lien on the Collateral in contravention of the provisions of this Indenture if and to the extent the Collateral or Liens are released in accordance with the terms of the applicable Security Documents, any applicable Intercreditor Agreements and this Article 11.

SECTION 11.03. After Acquired Property. From and after the Issue Date and subject to certain limitations, if the Company or any Subsidiary Guarantor acquires any property of the type that would constitute Collateral (excluding, for the avoidance of doubt, any Excluded Assets), it shall as soon as practicable after the acquisition thereof execute and deliver such security instruments, financing statements and such Officers’ Certificates and Opinions of Counsel as are required under this Indenture and the Collateral Agreement to vest in the Second Priority Collateral Agent a perfected security interest (subject only to Permitted Collateral Liens) in such after-acquired property and to have such after-acquired property added to the Collateral, and thereupon all provisions of this Indenture relating to the Collateral shall be deemed to

relate to such after-acquired property to the same extent and with the same force and effect. If granting a security interest in such property requires the consent of a third party, the Company or the applicable Subsidiary Guarantor will use commercially reasonable efforts to obtain such consent with respect to the second priority security interest for the benefit of the Second Priority Collateral Agent on behalf of the Holders. If such third party does not consent to the granting of the second priority security interest after the use of such commercially reasonable efforts, the applicable entity will not be required to provide such security interest.

SECTION 11.04. Reports, Certificates and Opinions. (a) To the extent that this Indenture is qualified under the TIA, the Company will cause TIA §313(b), relating to reports, and TIA §314(d), relating to the release of property or securities or relating to the substitution therefor of any property or securities to be subjected to the Lien of the Security Documents, to be complied with. Any certificate or opinion required by TIA §314(d) may be made by an Officer except in cases where TIA §314(d) requires that such certificate or opinion be made by an independent Person, which Person will be an independent engineer, appraiser or other expert selected or reasonably satisfactory to the Trustee.

(b) Notwithstanding anything to the contrary in Section 11.04(a), the Company will not be required to comply with all or any portion of TIA §314(d) if it determines, in good faith based on advice of counsel, that under the terms of TIA §314(d) and/or any interpretation or guidance as to the meaning thereof of the SEC and its staff, including “no action” letters or exemptive orders, all or any portion of TIA §314(d) is inapplicable to the released Collateral. The Company will also not be required to comply with TIA §314(d) with respect to any of the following:

(1) cash payments (including for the scheduled repayment of Indebtedness) in the ordinary course of business;

(2) sales or other dispositions of inventory in the ordinary course of business;

(3) collections, sales or other dispositions of accounts receivable in the ordinary course of business; and

(4) sales or other dispositions in the ordinary course of business of any property the use of which is no longer necessary or desirable in, and is not material to, the conduct of the business of the Company and its Subsidiaries;

provided, however, the Company’s right to rely on the above will be conditioned upon the Company’s delivering to the Trustee, within 30 calendar days following the end of each six-month period beginning on March 1 and September 1 of each year, an Officers’ Certificate to the effect that all releases during such six-month period in respect of which the Company did not comply with TIA §314(d) in reliance on the above were made in the ordinary course of business. The Company will otherwise comply with the provisions of TIA §314.

SECTION 11.05. Use of Trust Monies. To the extent received by the Trustee pursuant to the provisions of any Intercreditor Agreement, this Indenture, the Security Documents or otherwise, all Trust Monies shall be held by the Trustee as a part of the Collateral securing the Securities and, so long as no Event of Default has occurred and is continuing, shall either (i) be released as contemplated by Section 4.06 if such Trust Monies represent Net Cash Proceeds or (ii) to the extent not required to be applied pursuant to Section 4.06, at the direction of the Company be applied by the Trustee from time to time to the payment of the principal of, premium, if any, and interest on any Securities at maturity or upon redemption or retirement, or to the purchase of Securities upon tender or in the open market or otherwise, in each case in compliance with this Indenture. The Trustee shall be entitled to apply any Trust Monies to cure any Event of Default. Trust Monies deposited with the Trustee shall be invested in Cash Equivalents pursuant to the direction of the Company and, so long as no Default has occurred and is continuing, the Company shall be entitled to any interest or dividends accrued, earned or paid on such Cash Equivalents.

SECTION 12.01. Trust Indenture Act Controls. If any provision of this Indenture limits, qualifies or conflicts with another provision which is required to be included in this Indenture by the TIA, the required provision shall control.

SECTION 12.02. Notices. Any notice or communication shall be in writing and delivered in person or mailed by first-class mail addressed as follows:

The Company, any Subsidiary Guarantor or the Trustee by notice to the other may designate additional or different addresses for subsequent notices or communications.

Any notice or communication mailed to a Holder shall be mailed to the Holder at the Holder’s address as it appears on the registration books of the Registrar and shall be sufficiently given if so mailed within the time prescribed.

Failure to mail a notice or communication to a Holder or any defect in it shall not affect its sufficiency with respect to other Holders. If a notice or communication is mailed in the manner provided above, it is duly given, whether or not the addressee receives it.

The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, facsimile transmission or other similar unsecured electronic methods (including pdf files). If the party elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written instruction. The party providing electronic instructions agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse by third parties.

SECTION 12.03. Communication by Holders with Other Holders. Holders may communicate pursuant to TIA § 312(b) with other Holders with respect to their rights under this Indenture or the Securities. The Company, any Subsidiary Guarantor, the Trustee, the Registrar and anyone else shall have the protection of TIA § 312(c).

SECTION 12.04. Certificate and Opinion as to Conditions Precedent. Upon any request or application by the Company to the Trustee to take or refrain from taking any action under this Indenture, the Company shall furnish to the Trustee:

(1) an Officers’ Certificate in form and substance reasonably satisfactory to the Trustee stating that, in the opinion of the signers, all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with; and

(2) an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee stating that, in the opinion of such counsel, all such conditions precedent have been complied with.

SECTION 12.05. Statements Required in Certificate or Opinion. Each certificate or opinion with respect to compliance with a covenant or condition provided for in this Indenture shall include:

(1) a statement that the individual making such certificate or opinion has read such covenant or condition;

(2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(3) a statement that, in the opinion of such individual, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been complied with; and

(4) a statement as to whether or not, in the opinion of such individual, such covenant or condition has been complied with.

SECTION 12.06. When Securities Disregarded. In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which the Trustee knows are so owned shall be so disregarded. Also, subject to the foregoing, only Securities outstanding at the time shall be considered in any such determination.

SECTION 12.07. Rules by Trustee, Paying Agent and Registrar. The Trustee may make reasonable rules for action by or a meeting of Holders. The Registrar and the Paying Agent may make reasonable rules for their functions.

SECTION 12.08. Legal Holidays. If a payment date is a Legal Holiday, payment shall be made on the next succeeding day that is not a Legal Holiday. If a regular record date is a Legal Holiday, the record date shall not be affected.

SECTION 12.09. Governing Law. This Indenture, the Securities, the Security Documents and any Intercreditor Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

SECTION 12.10. WAIVER OF JURY TRIAL. EACH OF THE COMPANY, THE SUBSIDIARY GUARANTORS AND THE TRUSTEE, IN ITS CAPACITY AS TRUSTEE, HEREBY IRREVOCABLY WAIVES, TO THE FULLEST

EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE SECURITIES OR THE TRANSACTION CONTEMPLATED HEREBY.

SECTION 12.11. No Recourse Against Others. A director, officer, manager, employee, incorporator or stockholder, as such, of the Company or any Subsidiary Guarantor shall not have any liability for any obligations of the Company under the Securities or this Indenture or of such Subsidiary Guarantor under its Subsidiary Guarantee, the Security Documents or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder shall waive and release all such liability. The waiver and release shall be part of the consideration for the issue of the Securities.

SECTION 12.12. Successors. All agreements of the Company or any Subsidiary Guarantor in this Indenture and the Securities shall bind its successors. All agreements of the Trustee in this Indenture shall bind its successors.

SECTION 12.13. Multiple Originals. The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. One signed copy is enough to prove this Indenture.

Initial Securities initially resold pursuant to Rule 144A shall be issued initially in the form of one or more permanent global securities in definitive, fully registered form (collectively, the “Rule 144A Global Security”); Initial Securities initially resold to IAIs shall be issued initially in the form of one or more permanent global Securities in definitive, fully registered form (collectively, the “IAI Global Security”); and Initial Securities initially resold pursuant to Regulation S shall be issued initially in the form of one or more temporary global securities in fully registered form (collectively, the “Regulation S Global Security”), in each case without interest coupons and with the global securities legend and the applicable restricted securities legend set forth in Exhibit 1 hereto, which shall be deposited on behalf of the purchasers of the Initial Securities represented thereby with the Securities Custodian and registered in the name of the Depository or a nominee of the Depository, duly executed by the Company and authenticated by the Trustee as provided in the Indenture. Except as set forth in this Section 2.1(a), beneficial ownership interests in the Regulation S Global Security will not be exchangeable for interests in a Rule 144A Global Security, an IAI Global Security or any other Security prior to the expiration of the Distribution Compliance Period and then, after the expiration of the Distribution Compliance Period, may be exchanged for interests in a Rule 144A Global Security or an IAI Global Security only upon certification in form reasonably satisfactory to the Trustee that (i) beneficial ownership interests in such Regulation S Global Security are owned either by non-U.S. persons or U.S. persons who purchased such interests in a transaction that did not require registration under the Securities Act and (ii) in the case of an exchange for an IAI Global Security, certification that the interest in the Regulation S Global Security is being transferred to an institutional “accredited investor” under the Securities Act that is an institutional accredited investor acquiring the securities for its own account or for the account of an institutional accredited investor.

Beneficial interests in a Rule 144A Global Security or an IAI Global Security may be transferred to a Person who takes delivery in the form of an interest in a Regulation S Global Security, whether before or after the expiration of the Distribution Compliance Period, only if the transferor first delivers to the Trustee a written certificate (in the form provided in the Indenture) to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if applicable).

The Rule 144A Global Security, the IAI Global Security and the Regulation S Global Security are collectively referred to herein as “Global Securities”. The aggregate principal amount of the Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depository or its nominee as hereinafter provided.

(b) Book-Entry Provisions. This Section 2.1(b) shall apply only to a Global Security deposited with or on behalf of the Depository.

Members of, or participants in, the Depository (“Agent Members”) shall have no rights under the Indenture with respect to any Global Security held on their behalf by the Depository or by the Trustee as the custodian of the Depository or under such Global Security, and the Company, the Trustee and any agent of the Company or the Trustee shall be entitled to treat the Depository as the absolute owner of such Global

Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices of such Depository governing the exercise of the rights of a holder of a beneficial interest in any Global Security.

Such order shall specify the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated and, in the case of any issuance of Additional Securities pursuant to Section 2.13 of the Indenture, shall certify that such issuance is in compliance with Section 4.03 of the Indenture.

(a) Transfer and Exchange of Definitive Securities. When Definitive Securities are presented to the Registrar with a request:

(y) to exchange such Definitive Securities for an equal principal amount of Definitive Securities of other authorized denominations,

the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Definitive Securities surrendered for transfer or exchange:

(i) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing; and

(ii) if such Definitive Securities are required to bear a restricted securities legend, they are being transferred or exchanged pursuant to an effective registration statement under the Securities Act, pursuant to Section 2.3(b) or

pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable:

(A) if such Definitive Securities are being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect; or

(b) Restrictions on Transfer of a Definitive Security for a Beneficial Interest in a Global Security. A Definitive Security may not be exchanged for a beneficial interest in a Rule 144A Global Security, an IAI Global Security or a Regulation S Global Security except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Definitive Security, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with:

(i) certification, in the form set forth on the reverse of the Security, that such Definitive Security is either (A) being transferred to a QIB in accordance with Rule 144A, (B) being transferred to an IAI or (C) being transferred after expiration of the Distribution Compliance Period by a Person who initially purchased such Security in reliance on Regulation S to a buyer who elects to hold its interest in such Security in the form of a beneficial interest in the Regulation S Global Security; and

(ii) written instructions directing the Trustee to make, or to direct the Securities Custodian to make, an adjustment on its books and records with respect to such Rule 144A Global Security (in the case of a transfer pursuant to clause (b)(i)(A)), IAI Global Security (in the case of a transfer pursuant to clause (b)(1)(B)) or Regulation S Global Security (in the case of a transfer pursuant to clause (b)(i)(B)) to reflect an increase in the aggregate principal amount of the Securities represented by the Rule 144A Global Security, IAI Global Security or Regulation S Global Security, as applicable, such instructions to contain information regarding the Depository account to be credited with such increase,

then the Trustee shall cancel such Definitive Security and cause, or direct the Securities Custodian to cause, in accordance with the standing instructions and procedures existing between the Depository and the Securities Custodian, the aggregate principal amount of Securities represented by the Rule 144A Global Security, IAI Global Security or Regulation S Global Security, as applicable, to be increased by the aggregate principal amount of the Definitive Security to be exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Security, IAI Global Security or Regulation S Global Security, as applicable, equal to the principal amount of the Definitive Security so canceled. If no Rule 144A Global Securities, IAI Global Securities or Regulation S Global Securities, as applicable, are then outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officers’ Certificate of the Company, a new Rule 144A Global Security, IAI Global Security or Regulation S Global Security, as applicable, in the appropriate principal amount.

(c) Transfer and Exchange of Private Placement Securities. Private Placement Securities shall not be transferred and shall not be exchanged for beneficial interests in any Global Security unless the transferor first delivers a certificate substantially in the form of the certificate appended to the certificated form of Private Placement Security and, if requested, an Opinion of Counsel, that such transfer complies with the appropriate transfer restrictions applicable to such Private Placement Securities set forth in the subsequent sentences. Private Placement Securities shall only be sold, pledged or transferred (1) in a transaction permitted by the resale provisions of Rule 144 under the Securities Act (if available) or (2) pursuant to an effective registration statement under the Securities Act, in each case, (x) in a transaction the result of which is that any securities received in such transaction by the applicable purchaser, pledgee or recipient are no longer restricted securities under the Securities Act and (y) in accordance with any applicable laws of any state of the United States or any other applicable jurisdiction. Private Placement Securities will not be sold, pledged or otherwise disposed of until such time as all of the Initial Securities are no longer Transfer Restricted Initial Securities.

(i) The transfer and exchange of Global Securities or beneficial interests therein shall be effected through the Depository, in accordance with the Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depository therefor. A transferor of a beneficial interest in a Global Security shall deliver to the Registrar a written order given in accordance with the Depository’s procedures containing information regarding the participant account of the Depository to be credited with a beneficial interest in the Global Security. The Registrar shall, in accordance with such instructions instruct the Depository to credit to the account of the Person specified in such instructions a beneficial interest in the Global Security and to debit the account of the Person making the transfer the beneficial interest in the Global Security being transferred.

(ii) If the proposed transfer is a transfer of a beneficial interest in one Global Security to a beneficial interest in another Global Security, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Security to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Security from which such interest is being transferred.

(iii) Notwithstanding any other provisions of this Appendix (other than the provisions set forth in Section 2.4), a Global Security may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.

(iv) In the event that Global Security is exchanged for Definitive Securities pursuant to Section 2.4 of this Appendix, prior to the consummation of a Registered Exchange Offer or the effectiveness of a Shelf Registration Statement with respect to such Securities, such Securities may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Initial Securities intended to ensure that such transfers comply with Rule 144A, Regulation S or another applicable exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Company.

(e) Restrictions on Transfer of Regulation S Global Securities. During the Distribution Compliance Period, beneficial ownership interests in Regulation S Global Securities may only be sold, pledged or transferred in accordance with the Applicable Procedures and only (i) to the Company, (ii) in an offshore transaction in accordance with Regulation S or (iii) pursuant to an effective registration statement under the Securities Act, in each case in accordance with any applicable securities laws of any State of the United States.

Each certificate evidencing a Security offered in reliance on Regulation S shall, in addition to the foregoing, bear a legend in substantially the following form:

THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION ORIGINALLY EXEMPT FROM REGISTRATION UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE TRANSFERRED IN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON EXCEPT PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND ALL APPLICABLE STATE SECURITIES LAWS. TERMS USED ABOVE HAVE THE MEANINGS GIVEN TO THEM IN REGULATION S UNDER THE SECURITIES ACT.

IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS.

Each Private Placement Security shall bear a legend in substantially the following form:

REGISTRATION STATEMENT UNDER THE ACT, IN EACH CASE, (X) IN A TRANSACTION THE RESULT OF WHICH IS THAT ALL SECURITIES RECEIVED IN SUCH TRANSACTION BY THE APPLICABLE PURCHASER, PLEDGEE OR RECIPIENT ARE NO LONGER RESTRICTED SECURITIES UNDER THE ACT AND (Y) IN ACCORDANCE WITH ANY APPLICABLE LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION; PROVIDED, HOWEVER, NO SUCH SALE, PLEDGE OR DISPOSITION WILL BE MADE UNTIL SUCH TIME AS ALL THE INITIAL SECURITIES SOLD PURSUANT TO THE PURCHASE AGREEMENT ARE NO LONGER TRANSFER RESTRICTED INITIAL SECURITIES.

FOR PURPOSES HEREOF, THE FOLLOWING TERMS SHALL HAVE THE MEANING SET FORTH IN THE INDENTURE IDENTIFIED HEREIN: EXCHANGE SECURITIES; INITIAL PURCHASERS; INITIAL SECURITIES; ISSUE DATE; REGISTERED EXCHANGE OFFER AND SHELF REGISTRATION STATEMENT.

FOR PURPOSES HEREOF, “TRANSFER RESTRICTED INITIAL SECURITY” MEANS EACH INITIAL SECURITY ISSUED ON THE ISSUE DATE UNTIL (I) THE DATE ON WHICH SUCH TRANSFER RESTRICTED INITIAL SECURITY HAS BEEN EXCHANGED BY A PERSON (OTHER THAN A BROKER-DEALER) FOR A FREELY TRANSFERABLE EXCHANGE SECURITY IN A REGISTERED EXCHANGE OFFER, (II) FOLLOWING THE EXCHANGE BY A BROKER-DEALER IN THE REGISTERED EXCHANGE OFFER OF A SECURITY FOR AN EXCHANGE SECURITY, THE DATE ON WHICH SUCH EXCHANGE SECURITY IS SOLD TO A PURCHASER WHO RECEIVES FROM SUCH BROKER-DEALER ON OR PRIOR TO THE DATE OF SUCH SALE A COPY OF THE PROSPECTUS CONTAINED IN THE REGISTRATION STATEMENT FILED WITH THE SECURITIES EXCHANGE COMMISSION ON AN APPROPRIATE FORM UNDER THE ACT IN CONNECTION WITH THE REGISTERED EXCHANGE OFFER OR (III) THE DATE ON WHICH SUCH SECURITY HAS BEEN EFFECTIVELY REGISTERED UNDER THE ACT AND DISPOSED OF IN ACCORDANCE WITH THE SHELF REGISTRATION STATEMENT.

(ii) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Global Security) pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer Restricted Security for a certificated Security that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if (x) in the case of Security that is not a Private Placement Security, the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Security) and (y) in the case of any Private Placement Security, the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in accordance with the Private Placement legend.

(iii) After a transfer of any Initial Securities, Private Placement Securities or Private Exchange Securities pursuant to and during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial Securities, Private Placement Securities or Private Exchange Securities, as the case may be, all requirements pertaining to legends on such Initial Security, Private Placement Security or such Private Exchange Security will cease to apply, the requirements requiring any such Initial Security, Private Placement Security or such Private Exchange Security issued to certain Holders be issued in global form will cease to apply, and a certificated Initial Security, Private Placement Security or Private Exchange Security or an Initial Security, Private Placement Security or Private Exchange Security in global form, in each case without restrictive transfer legends, will be available to the transferee of the Holder of such Initial Securities, Private Placement Securities or Private Exchange Securities upon exchange of such transferring Holder’s certificated Initial Security, Private Placement Security or Private Exchange Security or directions to transfer such Holder’s interest in the Global Security, as applicable.

(iv) Upon the consummation of a Registered Exchange Offer with respect to the Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities and Exchange Securities in certificated or global form, in each case without the restricted securities legend set forth in Exhibit 1 hereto will be available to Holders that exchange such Initial Securities in such Registered Exchange Offer.

(v) Upon the consummation of a Private Exchange with respect to the Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Private

Exchange Securities in global form with the global securities legend and the applicable restricted securities legend set forth in Exhibit 1 hereto will be available to Holders that exchange such Initial Securities in such Private Exchange.

(g) Cancellation or Adjustment of Global Security.

(ii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depository participants, members or beneficial owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of the Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(b) Any Global Security that is transferable to the beneficial owners thereof pursuant to this Section 2.4 shall be surrendered by the Depository to the Trustee located at its principal corporate trust office in the Borough of Manhattan, The City of New York, located at 101 Barclay Street, New York, New York 1286, Attention: Corporate Trust Administration, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Security, an equal aggregate principal amount of Definitive Securities of authorized denominations. Any portion of a Global Security transferred pursuant to this Section 2.4 shall be executed, authenticated and delivered only in minimum denominations of $2,000 principal amount and any integral multiple of $1,000 in excess thereof and registered in such names as the Depository shall direct. Any Definitive Security delivered in exchange for an interest in the Transfer Restricted Security shall, except as otherwise provided by Section 2.3(f) hereof, bear the applicable restricted securities legend and definitive securities legend set forth in Exhibit 1 hereto.

(c) Subject to the provisions of Section 2.4(b) hereof, the registered Holder of a Global Security shall be entitled to grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the Securities.

(d) In the event of the occurrence of one of the events specified in Section 2.4(a) hereof, the Company shall promptly make available to the Trustee a reasonable supply of Definitive Securities in definitive, fully registered form without interest coupons. In the event that such Definitive Securities are not issued, the Company expressly acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to Section 6.06 of the Indenture, the right of any beneficial owner of Securities to pursue such remedy with respect to the portion of the Global Security that represents such beneficial owner’s Securities as if such Definitive Securities had been issued.

Rotech Healthcare Inc., a Delaware corporation, promises to pay to , or registered assigns, the principal sum of Dollars on March 15, 2018.

Interest Payment Dates: March 15 and September 15, commencing September 15, 2011.

Additional provisions of this Security are set forth on the other side of this Security.

Rotech Healthcare Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above; provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of 0.25% per annum (increasing by an additional 0.25% per annum after each consecutive 90-day period that occurs after the date on which such Registration Default occurs up to a maximum additional interest rate of 1.00% per annum, provided that the Company shall in no event be required to pay additional interest for more than one Registration Default at any given time) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured. Within a reasonable amount of time following the occurrence of a Registration Default, the Company will provide notice to the Trustee of such Registration Default. The Company will pay interest semiannually on March 15 and September 15 of each year, commencing September 15, 2011. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from March 17, 2011. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company will pay interest on overdue principal at the rate borne by this Security plus 1.00% per annum, and it will pay interest on overdue installments of interest at the same rate to the extent lawful.

The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the March 1 or September 1 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

Initially, The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

The Company issued the Securities under an Indenture dated as of March 17, 2011 (“Indenture”), among the Company, the Subsidiary Guarantors and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture and the Act for a statement of those terms.

The Securities are general secured obligations of the Company. The Company shall be entitled, subject to its compliance with Section 4.03 of the Indenture, to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Initial Securities and the Private Placement Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange for the Initial Securities will be treated as a single class for all purposes under the Indenture. The Indenture contains covenants that limit the ability of the Company and its subsidiaries to incur additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock; make investments; issue or sell capital stock of subsidiaries; engage in transactions with affiliates; create liens on assets; transfer or sell assets; guarantee indebtedness; restrict dividends or other payments of subsidiaries; consolidate, merge or transfer all or substantially all of its assets and the assets of its subsidiaries; and engage in sale/leaseback transactions. These covenants are subject to important exceptions and qualifications.

Except as set forth below, the Company shall not be entitled to redeem the Securities.

On and after March 15, 2015, the Company shall be entitled at its option to redeem all or a portion of the Securities upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed in percentages of principal amount on the redemption date), plus accrued and unpaid interest to 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 beginning March 15 of each of the years set forth below:

Unless the Company defaults in payment of the redemption price, interest will cease to accrue on the Securities or portions thereof called for redemption on the applicable redemption date.

In addition, at any time prior to March 15, 2014, the Company shall be entitled at its option on one or more occasions to redeem Securities (which includes Additional Securities, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the Securities (which includes Additional Securities, if any) originally issued at a redemption price (expressed as a percentage of principal amount) of 110.500%, plus accrued and unpaid interest to 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), with the Net Cash Proceeds from one or more Equity Offerings; provided, however, that (1) at least 65% of such aggregate principal amount of Securities (which includes Additional Securities and Exchange Securities, if any) remains outstanding immediately after the occurrence of each such redemption (other than Securities held, directly or indirectly, by the Company or its Subsidiaries); and (2) each such redemption occurs within 90 days after the date of the related Equity Offering.

Prior to March 15, 2015, the Company shall be entitled at its option to redeem all or a portion of the Securities at a redemption price equal to 100% of the principal amount of the Securities plus the Applicable Premium as of, and accrued and unpaid interest to, the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date).

interest on all Securities (or portions thereof) to be redeemed on the redemption date is deposited with the Paying Agent by 1:00 P.M., New York City time, on the redemption date and certain other conditions are satisfied, unless the Company defaults in payment of the redemption price, on and after such date interest ceases to accrue on such Securities (or such portions thereof) called for redemption.

Upon a Change of Control, any Holder of Securities will have the right to cause the Company to repurchase all or any part of the Securities of such Holder at a repurchase price equal to 101% of the principal amount of the Securities to be repurchased plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of holders of record on the relevant record date to receive interest due on the related interest payment date) as provided in, and subject to the terms of, the Indenture.

The payment by the Company of the principal of, and premium and interest on, the Securities is fully and unconditionally guaranteed on a joint and several senior secured basis by each of the Subsidiary Guarantors to the extent set forth in the Indenture.

The Securities will be secured by second-priority security interests (subject to Permitted Collateral Liens, including the first priority liens in favor of the First Priority Notes) in the Collateral, which security interests will be subject to the First Lien-Second Lien Intercreditor Agreement (as defined in the Indenture). Subject to exceptions described in the Indenture and the Collateral Agreement, the Collateral consists of substantially all of the property and assets of the Company and the Subsidiary Guarantors.

The Securities are in registered form without coupons in denominations of $2,000 principal amount and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 days before a selection of Securities to be redeemed or 15 days before an interest payment date.

The registered Holder of this Security may be treated as the owner of it for all purposes.

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of the Company’s and the Subsidiary Guarantors’ obligations under the Securities, the Subsidiary Guarantees and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to the redemption date or maturity, as the case may be.

Subject to certain exceptions set forth in the Indenture, (a) the Indenture, the Securities, the Security Documents and any Intercreditor Agreement may be amended with the written consent of the Holders of at least a majority in principal amount outstanding of the Securities and (b) any default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in principal amount outstanding of the Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Company, the Subsidiary Guarantors and the Trustee shall be entitled to amend the Indenture, the Securities, the Security Documents and any Intercreditor Agreement to cure any ambiguity, omission, defect or inconsistency, or to comply with Article 5 of the Indenture, or to provide for uncertificated Securities in addition to or in place of certificated Securities, or to add Guarantees with respect to the Securities, including Subsidiary Guarantees, or to secure the Securities, or to add additional covenants or surrender rights and powers conferred on the Company or the Subsidiary Guarantors, or to comply with any requirement of the SEC in connection with qualifying the Indenture under the Act, or to make any change that does not adversely affect the rights of any Holder, or to make amendments to provisions of the Indenture relating to the form, authentication, transfer and legending of the Securities.

If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities may declare all the Securities to be due and payable immediately. In the event of an acceleration that occurs prior to March 15, 2015, an amount will also become due and payable as of the day immediately preceding the day that the Securities were accelerated equal to the premium that would then be payable by the Company if the Company elected to redeem the Securities at its option on such date pursuant to the provisions described in Section 6 above. Certain events of bankruptcy or insolvency are Events of Default which will result in the Securities being due and payable immediately upon the occurrence of such Events of Default.

Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders.

Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

A director, officer, employee or stockholder, as such, of the Company or the Trustee shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security.

Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures the Company has caused CUSIP numbers to be printed on the Securities and has directed the Trustee to use CUSIP numbers in a notice of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

Each Holder of a Security, by acceptance hereof, acknowledges and agrees to the provisions of the Registration Rights Agreement, including the obligations of the Holders with respect to a registration and the indemnification of the Company to the extent provided therein.

THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

Notwithstanding the equal priority of the Liens established under Section 2.01(a), the Collateral Agent (acting on the instructions of the Applicable Authorized Representative) may deal with the Shared Collateral as if the Collateral Agent had a senior Lien on such Collateral. No Non-Controlling Authorized Representative or Non-Controlling Secured Party will contest, protest or object to any foreclosure proceeding or action brought by the Collateral Agent, the Applicable Authorized Representative or any Controlling Secured Party, or any other exercise by the Collateral Agent, the Applicable Authorized Representative or any Controlling Secured Party of any rights, remedies or powers with respect to the Shared Collateral, or seek to cause the Collateral Agent to do so. Nothing in this paragraph shall be construed to limit the rights and priorities of the Collateral Agent, any Authorized Representative or any other Secured Party with respect to any Collateral not constituting Shared Collateral.

(b) The Collateral Agent and each of the Authorized Representatives agrees that it will not accept any Lien on any asset of any Grantor securing Second Lien Obligations of any Class for the benefit of any Secured Party of such Class other than pursuant to the Second Lien Security Documents, other than (i) any funds deposited for the discharge or defeasance of Second Lien Obligations of any Class and (ii) any rights of set-off created under the Second Lien Credit Documents of any Class.

(c) Each of the Authorized Representatives agrees, for itself and on behalf of its Related Secured Parties, that neither such Authorized Representative nor its Related Secured Parties will (and each hereby waives any right to) challenge or contest or support any other Person in challenging or contesting, in any proceeding (including any Insolvency or Liquidation Proceeding), (i) the validity, attachment, creation, perfection, priority or enforceability of a Lien held by or on behalf of the Collateral Agent or any other Authorized Representative or any of its Related Secured Parties in all or any part of the Collateral, (ii) the validity, enforceability or effectiveness of any Second Lien Obligation of any Class or any Second Lien Security Document of any Class or (iii) the validity, enforceability or effectiveness of the priorities, rights or duties established by, or other provisions of, this Agreement; provided that nothing in this Agreement shall be construed to prevent or impair the rights of the Collateral Agent, any Authorized Representative or any of its Related Secured Parties to enforce this Agreement.

SECTION 2.04. No Interference; Payment Over. (a) Each of the Authorized Representatives, for itself and on behalf of its Related Secured Parties, agrees that (i) neither such Authorized Representative nor its Related Secured Parties will (and each hereby waives any right to) take or cause to be taken any action the purpose of which is, or could reasonably be expected to be, to interfere, hinder or delay, in any manner, whether by judicial proceedings or otherwise, any sale, transfer or other disposition of the Shared Collateral by the Collateral Agent, (ii) except as provided in Section 2.03, neither such Authorized Representative nor its Related Secured Parties shall have any right (A) to direct the Collateral Agent or any other Secured Party to exercise any right, remedy or power with respect to any Shared Collateral (including pursuant to any intercreditor agreement) or (B) to consent to the exercise by the Collateral Agent or any other Secured Party of any right, remedy or power with respect to any Shared Collateral, (iii) neither such Authorized Representative nor its Related Secured Parties will (and each hereby waives any right to) institute any suit or proceeding, or assert in any suit or proceeding any claim, against the Collateral Agent or any other Secured Party seeking damages from or other relief by way of specific performance, instructions or otherwise with respect to any Shared Collateral, and none of the Collateral Agent, any Applicable Authorized Representative or any other Secured Party shall be liable for any action taken or omitted to be taken by the Collateral Agent, such Applicable Authorized Representative or such other Secured Party with respect to any Shared Collateral in accordance with the provisions of this Agreement, and (iv) neither such Authorized Representative nor its Related Secured Parties will (and each hereby waives any right to) seek to have any Shared Collateral or any part thereof marshaled upon any foreclosure or other disposition of such Shared Collateral; provided that nothing in this Agreement shall be construed to prevent or impair the rights of the Collateral Agent or any Authorized Representative or any of its Related Secured Parties to enforce this Agreement.

(b) Each Authorized Representative, on behalf of itself and its Related Secured Parties, agrees that if such Authorized Representative or any of its Related Secured Parties shall at any time obtain possession of any Shared Collateral or receive any Proceeds (other than as a result of any application of Proceeds pursuant to Section 2.01(b)) at any time prior to the Discharge of Second Lien Obligations of each other Class, (i) such Authorized Representative or its Related Secured Party, as the case may

(a) Notwithstanding anything to the contrary in the Second Lien Credit Documents or Second Lien Security Documents (but subject to the provisions of Section [11.02] of the Indenture in the case of the release of the “Collateral” (as defined in the Indenture) from the Liens of the Security Documents), if at any time the Collateral Agent forecloses upon or otherwise exercises rights, remedies and powers against any Shared Collateral resulting in a disposition thereof, then (whether or not any Insolvency or Liquidation Proceeding is pending at the time) the Liens on such Shared Collateral in favor of the Collateral Agent, for the benefit of the Secured Parties of all Classes, will automatically be released and discharged; provided that any Proceeds realized therefrom shall be applied pursuant to Section 2.01(b).

(b) Each of the Authorized Representatives, for itself and on behalf of its Related Secured Parties, acknowledges and agrees that (i) the Collateral Agent may enter into any amendment or other modification to any Second Lien Security Document so long as the Collateral Agent receives a certificate of the Issuer stating that such amendment or other modification is permitted by the terms of the Second Lien Credit Documents of each Class and (ii) the Collateral Agent may enter into any amendment or other modification to any Second Lien Security Document solely as such Second Lien Security Document relates to Second Lien Obligations of a particular Class so long as (A) such amendment or modification is in accordance with the Second Lien Credit Documents of such Class and (B) such amendment or modification does not adversely affect the interests of the Secured Parties of any other Class.

(c) Each Authorized Representative agrees to execute and deliver (at the sole cost and expense of the Grantors) all such consents, confirmations, authorizations and other instruments as shall reasonably be requested by the Collateral Agent to evidence and confirm any release of Shared Collateral or amendment or modification to any Second Lien Security Document provided for in this Section.

SECTION 2.06. Certain Agreements with Respect to Bankruptcy and Insolvency Proceedings. (a) The Authorized Representative of each Class, for itself and on behalf of its Related Secured Parties, agrees that, if any Issuer or any other Grantor shall become subject to a case (a “Bankruptcy Case”) under the Bankruptcy Code and shall, as debtor-in-possession, move for approval of financing (“DIP Financing”) to be provided by one or more lenders (the “DIP Lenders”) under Section 364 of the Bankruptcy Code or any equivalent provision of any other Bankruptcy Law or the use of cash collateral under Section 363 of the Bankruptcy Code or any equivalent provision of any other Bankruptcy Law, neither such Authorized Representative nor its Related Secured Parties will raise any objection to any such financing or to the Liens on the

Shared Collateral securing any such financing (“DIP Financing Liens”) or to any use of cash collateral that constitutes Shared Collateral, in each case unless the Applicable Authorized Representative shall then oppose or object to such DIP Financing or such DIP Financing Liens or such use of cash collateral (and (i) to the extent that such DIP Financing Liens are senior to the Liens on any such Shared Collateral for the benefit of the Controlling Secured Parties, each Non-Controlling Secured Party will subordinate its Liens with respect to such Shared Collateral on the same terms as the Liens of the Controlling Secured Parties (other than any Liens of any Controlling Secured Parties constituting DIP Financing Liens) are subordinated thereto, and (ii) to the extent that such DIP Financing Liens rank pari passu with the Liens on any such Shared Collateral granted to secure the Second Lien Obligations of the Controlling Secured Parties, each Non-Controlling Secured Party will confirm the priorities with respect to such Shared Collateral as set forth herein), in each case so long as (A) the Secured Parties of such Class retain the benefit of their Liens on all such Shared Collateral subject to the DIP Financing Liens, including proceeds thereof arising after the commencement of the Bankruptcy Case, with such Liens having the same priority with respect to Liens of the Secured Parties of any other Class (other than any Liens of the Secured Parties of such other Class constituting DIP Financing Liens) as existed prior to the commencement of the Bankruptcy Case, (B) the Secured Parties of such Class are granted Liens on any additional collateral provided to the Secured Parties of any other Class as adequate protection or otherwise in connection with such DIP Financing or use of cash collateral, with such Liens having the same priority with respect to Liens of the Secured Parties of any other Class (other than any Liens of the Secured Parties of such other Class constituting DIP Financing Liens) as existed prior to the commencement of the Bankruptcy Case, (C) if any amount of such DIP Financing or cash collateral is applied to repay any Second Lien Obligations, such amount is applied in accordance with Section 2.01(b), and (D) if the Secured Parties of any Class are granted adequate protection, including in the form of periodic payments, in connection with such DIP Financing or use of cash collateral, the proceeds of such adequate protection are applied in accordance with Section 2.01(b); provided that the Secured Parties of each Class shall have a right to object to the grant, as security for the DIP Financing, of a Lien on any Collateral subject to Liens in favor of the Secured Parties of such Class or its Authorized Representative that shall not constitute Shared Collateral; and provided further that any Secured Party receiving adequate protection granted in connection with the DIP Financing or such use of cash collateral shall not object to any other Secured Party receiving adequate protection comparable to any such adequate protection granted to such Secured Party.

SECTION 2.07. Reinstatement. If, in any Insolvency or Liquidation Proceeding or otherwise, all or part of any payment with respect to the Second Lien Obligations of any Class previously made shall be rescinded for any reason whatsoever (including an order or judgment for disgorgement of a preference under the Bankruptcy Code, or any similar law), then the terms and conditions of Article II shall be fully applicable thereto until all the Second Lien Obligations of such Class shall again have been paid in full in cash.

SECTION 2.08. Insurance and Condemnation Awards. As between the Secured Parties, the Collateral Agent, acting at the direction of the Applicable Authorized Representative, shall have the exclusive right, subject to the rights of the Grantors under the Second Lien Security Documents, to settle and adjust claims in respect of Shared Collateral under policies of insurance covering or constituting Shared Collateral and to approve any award granted in any condemnation or similar proceeding, or any deed in lieu of condemnation, in respect of the Shared Collateral; provided that any Proceeds arising therefrom shall be subject to Section 2.01(b).

SECTION 2.09. Refinancings. The Second Lien Obligations of any Class may be Refinanced, in whole or in part, in each case, without notice to, or the consent of, any Secured Party of any other Class, all without affecting the priorities provided for herein or the other provisions hereof; provided that nothing in this Section shall affect any limitation on any such Refinancing that is set forth in the Second Lien Credit Documents of any such other Class; and provided further that, if any obligations of the Grantors in respect of such Refinancing Indebtedness shall be secured by Liens on any Shared Collateral, then such obligations and the holders thereof shall be subject to and bound by the provisions of this Agreement and the Authorized Representative of the holders of any such Refinancing Indebtedness shall have executed an Additional Authorized Representative Joinder Agreement.

SECTION 2.10. Possessory Collateral Agent as Gratuitous Bailee for Perfection. (a) The Collateral Agent agrees to hold any Shared Collateral constituting Possessory Collateral that is part of the Collateral in its possession or control (or in the possession or control of its agents or bailees) as gratuitous bailee for the benefit of each other Secured Party and any assignee solely for the purpose of perfecting the security interest granted in such Possessory Collateral, if any, pursuant to the applicable Second Lien Security Documents, in each case subject to the terms and conditions of this Section. Pending delivery to the Collateral Agent, each Authorized Representative agrees to hold any Shared Collateral constituting Possessory Collateral, from time to time in its possession, as gratuitous bailee for the benefit of each other Secured Party and any assignee, solely for the purpose of perfecting the security interest granted in such Possessory Collateral, if any, pursuant to the applicable Second Lien Security Documents, in each case, subject to the terms and conditions of this Section.

(b) The duties or responsibilities of the Collateral Agent and each Authorized Representative under this Section shall be limited solely to holding any Shared Collateral constituting Possessory Collateral as gratuitous bailee for the benefit of each other Secured Party for purposes of perfecting the Lien held by such Secured Parties therein.

Whenever, in connection with the exercise of its rights or the performance of its obligations hereunder, the Collateral Agent or the Authorized Representative of any

Class shall be required to determine the existence or amount of any Second Lien Obligations of any Class, or the Shared Collateral subject to any Lien securing the Second Lien Obligations of any Class (and whether such Lien constitutes a valid and perfected Lien), it may request that such information be furnished to it in writing by the Authorized Representative of such Class and shall be entitled to make such determination on the basis of the information so furnished; provided that if, notwithstanding such request, the Authorized Representative of the applicable Class shall fail or refuse reasonably promptly to provide the requested information, the requesting Collateral Agent or Authorized Representative shall be entitled to make any such determination by such method as it may, in the exercise of its good faith judgment, determine, including by reliance upon an Officers’ Certificate. The Collateral Agent and each Authorized Representative may rely conclusively, and shall be fully protected in so relying, on any determination made by it in accordance with the provisions of the preceding sentence (or as otherwise directed by a court of competent jurisdiction) and shall have no liability to any Grantor, any Secured Party or any other Person as a result of such determination or any action or not taken pursuant thereto.

SECTION 4.01. Appointment and Authority. (a) Each of the Authorized Representatives, for itself and on behalf of its Related Secured Parties, hereby irrevocably appoints The Bank of New York Mellon Trust Company, N.A. to act as the Collateral Agent hereunder and under each of the Second Lien Security Documents, and authorizes the Collateral Agent to take such actions and to exercise such powers as are delegated to the Collateral Agent by the terms hereof or thereof, including for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any Grantor to secure any of the Second Lien Obligations, together with such actions and powers as are reasonably incidental thereto. In addition, to the extent required under the laws of any jurisdiction other than the United States, each of the Authorized Representatives, for itself and on behalf of its Related Secured Parties, hereby grants to the Collateral Agent any required powers of attorney to execute any Second Lien Security Document governed by the laws of such jurisdiction on such Secured Party’s behalf. Without limiting the generality of the foregoing, the Collateral Agent is hereby expressly authorized to execute any and all documents (including releases) with respect to the Shared Collateral, and the rights of the Secured Parties with respect thereto, as contemplated by and in accordance with the provisions of this Agreement and the Second Lien Security Documents.

(b) Each of the Authorized Representatives, for itself and on behalf of its Related Secured Parties, acknowledges and agrees that the Collateral Agent shall be entitled, for the benefit of the Secured Parties, to sell, transfer or otherwise dispose of or deal with any Shared Collateral as provided herein and in the Second Lien Security Documents, without regard to any rights, remedies or powers to which the Non-Controlling Secured Parties would otherwise be entitled to as a result of their holding Second Lien Obligations. Without limiting the foregoing, each of the Authorized

Representatives, for itself and on behalf of its Related Secured Parties, agrees that none of the Collateral Agent, the Applicable Authorized Representative or any other Secured Party shall have any duty or obligation first to marshal or realize upon any type of Shared Collateral (or any other Collateral securing any of the Second Lien Obligations), or to sell, dispose of or otherwise liquidate all or any portion of such Shared Collateral (or any other Collateral securing any Second Lien Obligations), in any manner that would maximize the return to the Non-Controlling Secured Parties, notwithstanding that the order and timing of any such realization, sale, disposition or liquidation may affect the amount of proceeds actually received by the Non-Controlling Secured Parties from such realization, sale, disposition or liquidation. Each of the Authorized Representatives, for itself and on behalf of its Related Secured Parties, waives any claim they may now or hereafter have against the Collateral Agent or the Authorized Representative or any Secured Party of any other Class arising out of (i) any actions that the Collateral Agent or any such Authorized Representative or Secured Party takes or omits to take (including actions with respect to the creation, perfection or continuation of Liens on any Collateral, actions with respect to the foreclosure upon, sale or other disposition, release or depreciation of, or failure to realize upon, any of the Collateral and actions with respect to the collection of any claim for all or any part of the Second Lien Obligations from any account debtor, guarantor or any other party) in accordance with the Second Lien Security Documents or any other agreement related thereto or to the collection of the Second Lien Obligations or the valuation, use, protection or release of any security for the Second Lien Obligations, (ii) any election by any Applicable Authorized Representative or Secured Parties, in any proceeding instituted under the Bankruptcy Code, of the application of Section 1111(b) of the Bankruptcy Code or (iii) subject to Section 2.06, any borrowing by, or grant of a security interest or administrative expense priority under Section 364 of the Bankruptcy Code or any equivalent provision of any other Bankruptcy Law by, the Issuer or any of its Subsidiaries, as debtor-in-possession. Notwithstanding any other provision of this Agreement, the Collateral Agent shall not accept any Shared Collateral in full or partial satisfaction of any Second Lien Obligations pursuant to Section 9-620 of the Uniform Commercial Code of any jurisdiction without the consent of each Authorized Representative representing Secured Parties for whom such Collateral constitutes Shared Collateral.

(c) Each of the Authorized Representatives, for itself and on behalf of its Related Secured Parties, acknowledges and agrees that, upon any other obligations being designated hereunder as Additional Second Lien Obligations or any other Person becoming an Additional Authorized Representative or any other Persons becoming Additional Secured Parties, the Collateral Agent will continue to act in its capacity as Collateral Agent in respect of the then existing Authorized Representatives and Secured Parties and such Additional Authorized Representative and Additional Secured Parties.

SECTION 4.02. Rights as a Secured Party. (a) The Person serving as the Collateral Agent hereunder shall have the same rights and powers in its capacity as a Secured Party of any Class as any other Secured Party of such Class and may exercise the same as though it were not the Collateral Agent and the term “Secured Party”, “Secured Parties”, “Indenture Secured Party”, “Indenture Secured Parties”, “Additional Secured Party” or “Additional Secured Parties”, as applicable, shall, unless otherwise expressly

indicated or unless the context otherwise requires, include the Person serving as the Collateral Agent hereunder in its individual capacity. The Person serving as the Collateral Agent and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Issuer or any of its Subsidiaries or other Affiliate thereof as if such Person were not the Collateral Agent hereunder and without any duty to account therefor to any other Secured Party.

SECTION 4.03. Exculpatory Provisions. The Collateral Agent shall not have any duties or obligations except those expressly set forth herein and in the other Second Lien Security Documents. Without limiting the generality of the foregoing, the Collateral Agent:

(i) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing;

(ii) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the Second Lien Security Documents that the Collateral Agent is required to exercise as directed in writing by the Applicable Authorized Representative; provided that the Collateral Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Collateral Agent to liability or that is contrary to any Second Lien Security Document or applicable law;

(iii) shall not, except as expressly set forth in this Agreement and in the Second Lien Security Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Issuer, any of its Subsidiaries or any of its Affiliates that is communicated to or obtained by the Person serving as the Collateral Agent or any of its Affiliates in any capacity;

(iv) shall not be liable for any action taken or not taken by it (A) with the consent or at the request of the Applicable Authorized Representative or (B) in the absence of its own gross negligence or wilful misconduct or (C) in reliance on an Officers’ Certificate stating that such action is permitted by the terms of this Agreement;

(v) shall be deemed not to have knowledge of any Default or Event of Default under any Second Lien Credit Documents of any Class unless and until notice describing such Default or Event Default is given to the Collateral Agent by the Authorized Representative of such Class or the Issuer in accordance with the applicable Second Lien Credit Document; and

(vi) shall not be responsible for or have any duty to ascertain or inquire into (A) any statement, warranty or representation made in or in

connection with this Agreement or any Second Lien Security Document, (B) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (C) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (D) the validity, enforceability, effectiveness or genuineness of this Agreement, any Second Lien Security Document or any other agreement, instrument or document, or the validity, attachment, creation, perfection, priority or enforceability of any Lien purported to be created by the Second Lien Security Documents, (E) the value or the sufficiency of any Collateral for Second Lien Obligations of any Class or (F) the satisfaction of any condition set forth in any Second Lien Credit Document, other than to confirm receipt of items expressly required to be delivered to the Collateral Agent.

SECTION 4.04. Reliance by Collateral Agent. The Collateral Agent shall be entitled to rely, and shall not incur any liability for relying, upon any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Collateral Agent also shall be entitled to rely, and shall not incur any liability for relying, upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person. The Collateral Agent may consult with legal counsel (who may be counsel for the Issuer, any other Grantor or any Authorized Representative), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

SECTION 4.05. Delegation of Duties. The Collateral Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Second Lien Security Document by or through any one or more sub-agents appointed by the Collateral Agent. The Collateral Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Affiliates. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Affiliates of the Collateral Agent and any such sub-agent, and shall apply to their respective activities as the Collateral Agent.

SECTION 4.06. Resignation of Collateral Agent. The Collateral Agent may at any time give notice of its resignation as Collateral Agent under this Agreement and the Second Lien Security Documents to each Authorized Representative and the Issuer. Upon receipt of any such notice of resignation, the Applicable Authorized Representative shall have the right, in consultation with the Issuer, to appoint a successor. If no such successor shall have been so appointed by the Applicable Authorized Representative and shall have accepted such appointment within 30 days after the retiring Collateral Agent gives notice of its resignation, then the retiring Collateral Agent may, on behalf of the Secured Parties, appoint a successor Collateral Agent meeting the qualifications set forth above; provided that if the Collateral Agent shall notify each Authorized Representative and the Issuer that no qualifying Person has accepted such

appointment, then such resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Collateral Agent shall be discharged from its duties and obligations hereunder and under the Second Lien Security Documents (except that in the case of any Collateral held by the Collateral Agent on behalf of the Secured Parties under any Second Lien Security Document, the retiring Collateral Agent shall continue to hold such Collateral solely for purposes of maintaining the perfection of the security interests of the Secured Parties therein until such time as a successor Collateral Agent is appointed but with no obligation to take any further action at the request of the Applicable Authorized Representative or any other Secured Parties) and (b) all payments, communications and determinations provided to be made by, to or through the Collateral Agent shall instead be made by or to each Authorized Representative directly, until such time as the Applicable Authorized Representative appoints a successor Collateral Agent as provided above. Upon the acceptance of a successor’s appointment as Collateral Agent hereunder and under the Second Lien Security Documents, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Collateral Agent, and the retiring Collateral Agent shall be discharged from all of its duties and obligations hereunder or under the Second Lien Security Documents (if not already discharged therefrom as provided above). Notwithstanding the resignation of the Collateral Agent hereunder and under the Second Lien Security Documents, the provisions of this Article and the equivalent provision of any Additional Second Lien Document shall continue in effect for the benefit of such retiring Collateral Agent, its sub-agents and their respective Related Secured Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Collateral Agent was acting as Collateral Agent. Upon any notice of resignation of the Collateral Agent hereunder and under the Second Lien Security Documents, the Issuer agrees to use commercially reasonable efforts to transfer (and maintain the validity and priority of) the Liens in favor of the retiring Collateral Agent under the Second Lien Security Documents to the successor Collateral Agent.

SECTION 4.07. Collateral Matters. Each of the Secured Parties irrevocably authorizes the Collateral Agent, at its option and in its discretion:

(a) to release any Lien on any property granted to or held by the Collateral Agent under any Second Lien Security Document in accordance with Sections 2.03 and 2.05 or upon receipt of an Officers’ Certificate stating that such release is permitted by the terms of the Second Lien Credit Documents or as required by the First Lien-Second Lien Intercreditor Agreement; and

(b) to release any Grantor from its obligations under the Second Lien Security Documents upon receipt of an Officers’ Certificate and Opinion of Counsel stating that such release is permitted by the terms of the Second Lien Credit Documents.

SECTION 5.01. Information. The Collateral Agent or the Authorized Representative or Secured Parties of any Class shall have no duty to disclose to any Secured Party of any other Class any information relating to the Issuer or any of its Subsidiaries, or any other circumstance bearing upon the risk of nonpayment of any of the Second Lien Obligations, that is known or becomes known to any of them or any of their Affiliates. If the Collateral Agent or the Authorized Representative or any Secured Party of any Class, in its sole discretion, undertakes at any time or from time to time to provide any such information to, as the case may be, the Authorized Representative or any Secured Party of any other Class, it shall be under no obligation (i) to make, and shall not be deemed to have made, any express or implied representation or warranty, including with respect to the accuracy, completeness, truthfulness or validity of the information so provided, (ii) to provide any additional information or to provide any such information on any subsequent occasion or (iii) to undertake any investigation.

SECTION 5.02. No Warranties or Liability. (a) Each Authorized Representative, for itself and on behalf of its Related Secured Parties, acknowledges and agrees that neither the Collateral Agent nor the Authorized Representative or any Secured Party of any other Class has made any express or implied representation or warranty, including with respect to the execution, validity, legality, completeness, collectability or enforceability of any of the Second Lien Credit Documents, the ownership of any Shared Collateral or the perfection or priority of any Liens thereon. The Authorized Representative and the Secured Parties of any Class will be entitled to manage and supervise their loans and other extensions of credit in the manner determined by them.

(b) No Authorized Representative or Secured Parties of any Class shall have any express or implied duty to the Authorized Representative or any Secured Party of any other Class to act or refrain from acting in a manner that allows, or results in, the occurrence or continuance of a Default or an Event of Default under any Second Lien Credit Document (other than, in each case, this Agreement), regardless of any knowledge thereof that they may have or be charged with.

The Issuer may, at any time and from time to time, subject to any limitations contained in the Second Lien Credit Documents in effect at such time, designate additional Indebtedness and related obligations that are, or are to be, secured by Liens on any assets of the Issuer or any other Grantor that would, if such Liens were granted, constitute Shared Collateral as “Additional Second Lien Obligations” by delivering to the Collateral Agent and each Authorized Representative party hereto at such time an Officers’ Certificate:

(a) describing the Indebtedness and other obligations being designated as Additional Second Lien Obligations, and including a statement of the maximum aggregate outstanding principal amount of such Indebtedness as of the date of such certificate;

(b) setting forth the Additional Second Lien Documents under which such Additional Second Lien Obligations are issued or incurred or the guarantees of such Additional Second Lien Obligations are, or are to be, created, and attaching copies of such Additional Second Lien Documents as each Grantor has executed and delivered to the Person that serves as the administrative agent, trustee or a similar representative for the holders of such Additional Second Lien Obligations (such Person being referred to as the “Additional Authorized Representative”) with respect to such Additional Second Lien Obligations on the closing date of such Additional Second Lien Obligations, certified as being true and complete by an Officers’ Certificate;

(d) certifying that the incurrence of such Additional Second Lien Obligations, the creation of the Liens securing such Additional Second Lien Obligations and the designation of such Additional Second Lien Obligations as “Additional Second Lien Obligations” hereunder do not violate or result in a default under any provision of any Second Lien Credit Documents in effect at such time;

(e) certifying that the Additional Second Lien Documents authorize the Additional Authorized Representative to become a party hereto by executing and delivering an Additional Authorized Representative Joinder Agreement and provide that upon such execution and delivery, such Additional Second Lien Obligations and the holders thereof shall become subject to and bound by the provisions of this Agreement; and

(f) attaching a fully completed Authorized Representative Joinder Agreement executed and delivered by the Additional Authorized Representative.

Upon the delivery of such certificate and the related attachments as provided above, the obligations designated in such notice as “Additional Second Lien Obligations” shall become Additional Second Lien Obligations for all purposes of this Agreement.

SECTION 7.01. Notices. All notices and other communications provided for herein shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by telecopy, as follows:

SECTION 7.02. Waivers; Amendment; Joinder Agreements. (a) No failure or delay on the part of any party hereto in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties hereto are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by any party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on any party hereto in any case shall entitle such party to any other or further notice or demand in similar or other circumstances.

(b) Neither this Agreement nor any provision hereof may be waived, amended or otherwise modified except pursuant to an agreement or agreements in writing entered into by the Collateral Agent and each Authorized Representative then party hereto; provided that no such agreement shall by its terms amend, modify or otherwise affect the rights or obligations of any Grantor without the Issuer’s prior written consent; provided further that (i) without the consent of any party hereto, (A) this Agreement may be supplemented by an Authorized Representative Joinder Agreement, and an Additional Authorized Representative may become a party hereto, in accordance with Article VI and (B) this Agreement may be supplemented by a Grantor Joinder Agreement, and a Subsidiary may become a party hereto, in accordance with Section 7.13, and (ii) in connection with any Refinancing of Second Lien Obligations of any Class, or the incurrence of Additional Second Lien Obligations of any Class, the Collateral Agent and the Authorized Representatives then party hereto shall enter (and are hereby authorized to

SECTION 7.03. Parties in Interest. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, as well as the other Secured Parties, all of whom are intended to be bound by, and to be third party beneficiaries of, this Agreement.

SECTION 7.04. Effectiveness; Survival. This Agreement shall become effective when executed and delivered by the parties hereto. All covenants, agreements, representations and warranties made by any party in this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement. This Agreement shall continue in full force and effect notwithstanding the commencement of any Insolvency or Liquidation Proceeding against the Issuer or any of its Subsidiaries.

2.3 Agreements Regarding Actions to Perfect Liens. (a) The Junior Priority Representative on behalf of itself and the Junior Priority Secured Parties agrees that UCC-1 financing statements, patent, trademark or copyright filings or other filings or recordings filed or recorded by or on behalf of the Junior Priority Representative shall be in form satisfactory to the Second Priority Representative.

(b) The Junior Priority Representative agrees on behalf of itself and the Junior Priority Secured Parties that all Junior Priority Security Documents entered into on or about the date hereof shall contain the following notation: “The lien and security interest created by this Agreement on the property described herein is junior and subordinate, in accordance with the provisions of the Junior Lien Intercreditor Agreement dated as of [ ], among The Bank of New York Mellon Trust Company, N.A., [ ], Rotech Healthcare Inc. and the other Grantors referred to therein, as amended from time to time, to the lien and security interest on such property created by any similar instrument now or hereafter granted to The Bank of New York Mellon Trust Company, N.A., as collateral agent under the Second Priority Documents, and its successors and assigns, in such property.” The Junior Priority Representative agrees on behalf of itself and the Junior Priority Secured Parties that all other Junior Priority Security Documents shall bear an identical or, in the event that the Existing Second Priority Agreement is no longer extant or The Bank of New York Mellon Trust Company, N.A. shall cease to be the Second Priority Representative, a substantially similar notation.

(c) The Second Priority Representative hereby agrees that, to the extent that it holds, or a third party holds on its behalf, physical possession of or “control” (as defined in the Uniform Commercial Code) (or any similar concept under foreign law) over Shared Collateral pursuant to the Second Priority Security Documents, such possession or control is also for the benefit of the Junior Priority Representative and the Junior Priority

Secured Parties solely to the extent required to perfect their security interest in such Shared Collateral (such bailment being intended, among other things, to satisfy the requirements of Sections 8-106(d)(3), 8-301(a)(2) and 9-313(c) of the Uniform Commercial Code). Nothing in the preceding sentence shall be construed to impose any duty on the Second Priority Representative (or any third party acting on its behalf) with respect to such Shared Collateral or provide the Junior Priority Representative or any Junior Priority Secured Party with any rights with respect to such Shared Collateral beyond those specified in this Agreement and the Junior Priority Security Documents; provided that subsequent to the occurrence of the Second Priority Obligations Payment Date, the Second Priority Representative shall (i) deliver to the Junior Priority Representative, at the Issuer’s sole cost and expense, the Shared Collateral in its possession or control together with any necessary endorsements to the extent required by the Junior Priority Documents or (ii) direct and deliver such Shared Collateral as a court of competent jurisdiction otherwise directs; provided, however, that the provisions of this Agreement are intended solely to govern the respective Lien priorities as between the Second Priority Secured Parties and the Junior Priority Secured Parties and shall not impose on the Second Priority Secured Parties any obligations in respect of the disposition of any Shared Collateral (or any proceeds thereof) that would conflict with prior perfected Liens or any claims thereon in favor of any other Person that is not a Secured Party.

2.4 No New Liens. So long as the Second Priority Obligations Payment Date has not occurred, the parties hereto agree that (a) there shall be no Lien, and no Grantor shall have any right to create any Lien, on any assets of any Grantor securing any Junior Priority Obligation if those same assets are not subject to, and do not become subject to, a Lien securing the Second Priority Obligations and (b) if any Junior Priority Secured Party shall acquire or hold any Lien on any assets of any Grantor securing any Junior Priority Obligation, which assets are not also subject to the first-priority Lien of the Second Priority Representative under the Second Priority Documents, then the Junior Priority Representative shall be deemed to also hold and have held such Lien for the benefit of the Second Priority Secured Parties and shall promptly notify the Second Priority Representative of the existence of such Lien and, upon demand by the Second Priority Representative, will without the need for any further consent of any Junior Priority Secured Party, notwithstanding anything to the contrary in any other Junior Priority Document, either (i) release such Lien or (ii) assign it to the Second Priority Representative as security for the Second Priority Obligations (in which case the Junior Priority Representative may retain a junior lien on such assets subject to the terms hereof). To the extent that the foregoing provisions are not complied with for any reason, without limiting any other rights and remedies available to the Second Priority Secured Parties, the Junior Priority Representative and the Junior Priority Secured Parties agree that any amounts received by or distributed to any of them pursuant to or as a result of Liens granted in contravention of this Section 2.4 shall be subject to Section 4.1.

2.5 No Duties of Second Priority Representative. Neither the Second Priority Representative nor any Second Priority Secured Party will have any duties or other obligations to any Junior Priority Secured Party with respect to the Shared Collateral, other than, in the case of the Second Priority Representative, to transfer to the Junior

Priority Representative any such Shared Collateral in which the Junior Priority Representative continues to hold a security interest and that is remaining following (x) any sale, transfer or other disposition of such Shared Collateral (in each case, unless the Lien securing the Junior Priority Obligations on all such Shared Collateral is terminated and released prior to or concurrently with such sale, transfer, disposition, payment or satisfaction) and (y) the payment and satisfaction in full of such Second Priority Obligations and termination of any commitment to extend credit that would constitute such Second Priority Obligations, or to the extent the Second Priority Representative is in possession of any part of such Shared Collateral after such payment and satisfaction in full and termination, the part thereof remaining, in each case without representation or warranty on the part of the Second Priority Representative or any holder of Second Priority Obligations. Without limiting the foregoing, neither the Second Priority Representative nor any holder of any Second Priority Obligations will have any duty or obligation to marshal or realize upon the Shared Collateral, or to sell, dispose or otherwise liquidate all or any portion of the Shared Collateral, in any manner that would maximize the return to the Junior Priority Secured Parties notwithstanding that the order and timing of any such realization, sale, disposition or liquidation may affect the amount of the proceeds actually received by the Junior Priority Secured Parties from such realization, sale, disposition or liquidation. The Junior Priority Representative, for itself and on behalf of each Junior Priority Secured Party, waives any claim the Junior Priority Representative or such Junior Priority Secured Party may now or hereafter have against the Second Priority Representative or any Second Priority Secured Party (or their representatives) arising out of any actions which the Second Priority Representative or the Second Priority Secured Parties take or omit to take (including actions with respect to the creation, perfection or continuation of Liens on any Shared Collateral, actions with respect to the foreclosure upon, sale, release or depreciation of, or failure to realize upon, any of the Shared Collateral and actions with respect to the collection of any claim for all or any part of the Second Priority Obligations from any account debtor, guarantor or any other party) in accordance with the Second Priority Security Documents or any other agreement related thereto or to the collection of the Second Priority Obligations or the valuation, use, protection or release of any Shared Collateral.

2.6 Further Assurances. Each Second Priority Representative, for itself and on behalf of the Second Priority Secured Parties, and the Junior Priority Representative, for itself and on behalf of the Junior Priority Secured Parties, and each Grantor party hereto, for itself and on behalf of its subsidiaries, agrees that it will execute, or will cause to be executed, any and all further documents, agreements and instruments, and take all such further actions, as may be required under any applicable law, or which the Second Priority Representative or the Junior Priority Representative may reasonably request, to effectuate the terms of this Agreement, including the relative Lien priorities provided for herein.

3.1 Exclusive Enforcement. Until the Second Priority Obligations Payment Date has occurred, whether or not an Insolvency Proceeding has been commenced by or against any Grantor, the Second Priority Secured Parties shall have the exclusive right to

take and continue any Enforcement Action and make determinations regarding the release, dispositions or restrictions with respect to the Shared Collateral, without any consultation with or consent of any Junior Priority Secured Party, but subject to the proviso set forth in Section 5.1. In exercising rights and remedies with respect to the Shared Collateral, the Second Priority Secured Parties may enforce the provisions of the Second Priority Documents and exercise remedies thereunder, all in such order and in such manner as they may determine in the exercise of their sole discretion. Such exercise and enforcement shall include the rights of an agent appointed by any of them to sell or otherwise dispose of the Shared Collateral upon foreclosure, to incur expenses in connection with such sale or disposition and to exercise all rights and remedies of a secured creditor under the Uniform Commercial Code and of a secured creditor under the Bankruptcy Law of any applicable jurisdiction.

3.2 Standstill and Waivers. The Junior Priority Representative, on behalf of itself and the Junior Priority Secured Parties, agrees that, until the Second Priority Obligations Payment Date has occurred, subject to the proviso set forth in Section 5.1:

(a) they will not take or cause to be taken any action, the purpose or effect of which is, or could be, to make any Lien in respect of any Junior Priority Obligation pari passu with or senior to, or to give any Junior Priority Secured Party any preference or priority relative to, the Liens with respect to the Second Priority Obligations or the Second Priority Secured Parties with respect to any of the Shared Collateral;

(b) they will not challenge or question in any proceeding the validity or enforceability of any security interest in the Shared Collateral in favor of any Second Priority Obligations, the validity, attachment, perfection or priority of any Second Priority Lien or the validity or enforceability of the priorities, rights or duties established by (or other provisions of) this Agreement;

(c) they will not contest, oppose, object to, interfere with, challenge, hinder or delay, in any manner, whether by judicial proceedings (including the filing of an Insolvency Proceeding) or otherwise, any foreclosure, sale, lease, exchange, transfer or other disposition of the Shared Collateral or any other Second Priority Collateral by any Second Priority Secured Party or any other Enforcement Action taken (or any forbearance from taking any Enforcement Action) by or on behalf of any Second Priority Secured Party;

(d) they have no right to (i) direct either the Second Priority Representative or any Second Priority Secured Party to exercise any right, remedy or power with respect to the Shared Collateral or pursuant to the Second Priority Security Documents or (ii) consent or object to the exercise by the Second Priority Representative or any Second Priority Secured Party of any right, remedy or power with respect to the Shared Collateral or pursuant to the Second Priority Security Documents or to the timing or manner in which any such right is exercised or not exercised (or, to the extent they may have any such right

described in this clause (d), whether as a junior lien creditor or otherwise, they hereby irrevocably waive such right);

(e) they will not object to the forbearance by the Second Priority Secured Parties from bringing or pursuing any foreclosure proceeding or action or any other exercise of any rights or remedies relating to the Shared Collateral or any other Second Priority Collateral;

(f) they will not oppose or seek to challenge any claim by any Second Priority Secured Party for allowance in any judicial or Insolvency Proceedings consisting of post-petition interest, fees or expenses (it being understood that the Second Priority Secured Parties will not contest any similar action by any Junior Priority Secured Party);

(g) they will not institute any suit or other proceeding or assert in any suit, Insolvency Proceeding or other proceeding any claim against any Second Priority Secured Party seeking damages from or other relief by way of specific performance, instructions or otherwise, with respect to, and no Second Priority Secured Party shall be liable for, any action taken or omitted to be taken by any Second Priority Secured Party with respect to the Shared Collateral or pursuant to the Second Priority Documents;

(h) they will not make any judicial or nonjudicial claim or demand or commence any judicial or non-judicial proceedings against any Grantor or any of its subsidiaries or affiliates under or with respect to any Junior Priority Security Document seeking payment or damages from or other relief by way of specific performance, instructions or otherwise under or with respect to any Junior Priority Security Document or exercise any right, remedy or power under or with respect to, or otherwise take any action to enforce, any Junior Priority Security Document;

(i) they will not commence judicial or nonjudicial foreclosure proceedings with respect to, seek to have a trustee, receiver, liquidator or similar official appointed for or over, or attempt any action to take possession of any Shared Collateral, or exercise any right, remedy or power with respect to, or otherwise take any action to enforce their interest in or realize upon, the Shared Collateral or pursuant to the Junior Priority Security Documents;

(j) they will not seek, and hereby waive any right, to have the Shared Collateral or any part thereof marshaled upon any foreclosure or other disposition of the Shared Collateral and hereby waive, to the fullest extent permitted by law, any right to demand, request, plead or otherwise assert or claim the benefit of, any marshalling, appraisal, valuation or other similar right that may otherwise be available under applicable law with respect to the Shared Collateral or any other similar rights a junior secured creditor may have under applicable law; and

(k) they will not attempt, directly or indirectly, whether by judicial proceedings or otherwise, to challenge the enforceability of any provision of this Agreement.

3.3 Judgment Creditors. In the event that any Junior Priority Secured Party becomes a judgment lien creditor as a result of its enforcement of its rights as an unsecured creditor, such judgment lien shall be subject to the terms of this Agreement for all purposes (including in relation to the Second Priority Liens and the Second Priority Obligations) to the same extent as all other Liens securing the Junior Priority Obligations are subject to the terms of this Agreement.

3.4 Cooperation. The Junior Priority Agent, on behalf of itself and the Junior Priority Secured Parties, agrees that each of them shall take such actions as the Second Priority Representative shall request in connection with the exercise by the Second Priority Secured Parties of their rights set forth herein.

3.5 No Additional Rights For the Grantors Hereunder. Except as provided in Section 3.6, if any Second Priority Secured Party or Junior Priority Secured Party shall enforce its rights or remedies in violation of the terms of this Agreement, no Grantor shall be entitled to use such violation as a defense to any action by any Second Priority Secured Party or Junior Priority Secured Party, or to assert such violation as a counterclaim or basis for set off or recoupment against any Second Priority Secured Party or Junior Priority Secured Party.

3.6 Actions Upon Breach. (a) If any Junior Priority Secured Party, contrary to this Agreement, commences or participates in any action or proceeding against any Grantor or the Shared Collateral, such Grantor, with the prior written consent of the Second Priority Representative, may interpose as a defense or dilatory plea the making of this Agreement, and any Second Priority Secured Party may intervene and interpose such defense or plea in its or their name or in the name of such Grantor.

(b) Should any Junior Priority Secured Party, contrary to this Agreement, in any way take, attempt to take or threaten to take any action with respect to the Shared Collateral (including any attempt to realize upon or enforce any remedy with respect to this Agreement), or take any other action in violation of this Agreement, or fail to take any action required by this Agreement, this Agreement shall create an irrebuttable presumption and admission by such Junior Priority Secured Party that any Second Priority Secured Party (in its own name or in the name of the relevant Grantor) or the relevant Grantor may obtain relief against such Junior Priority Secured Party by injunction, specific performance and/or other appropriate equitable relief, it being understood and agreed by the Junior Priority Representative on behalf of each Junior Priority Secured Party that (i) the Second Priority Secured Parties’ damages from such actions of any Junior Priority Secured Party may at that time be difficult to ascertain and may be irreparable and the harm to the Second Priority Secured Parties may not be adequately compensated in damages and (ii) each Junior Priority Secured Party waives any defense that the Grantors and/or the Second Priority Secured Parties cannot demonstrate damage and/or be made whole by the awarding of damages.

SECTION 4. Application of Proceeds of Shared Collateral; Dispositions and Releases of Shared Collateral; Inspection and Insurance.

4.1 Application of Proceeds; Turnover Provisions. All proceeds of Shared Collateral (including any interest earned thereon) resulting from the sale, collection or other disposition of Shared Collateral resulting from any Enforcement Action or that occurs after any Event of Default (as defined in the Second Priority Documents), whether or not pursuant to an Insolvency Proceeding, or during the pendency of any Insolvency Proceeding shall be distributed as follows: first to the Second Priority Representative for application to the Second Priority Obligations in accordance with the terms of the Second Priority Documents, until the Second Priority Obligations Payment Date has occurred and thereafter, to the Junior Priority Representative for application in accordance with the terms of the Junior Priority Documents. If any Junior Priority Secured Party obtains possession of the Shared Collateral or realizes any proceeds or payment in respect of the Shared Collateral, pursuant to any Junior Priority Security Documents or by the exercise of any rights available to such Junior Priority Secured Party under applicable law or in any Insolvency Proceeding or through any other exercise of remedies, at any time when any Second Priority Obligations secured or intended to be secured by such Shared Collateral remains outstanding or any commitment to extend credit that would constitute Second Priority Obligations secured or intended to be secured by such Shared Collateral remains in effect, then such Junior Priority Secured Party will hold such Shared Collateral, proceeds or payments in trust for the Second Priority Representative and the holders of any Second Priority Obligations and transfer such Shared Collateral, proceeds or payments, as the case may be, to the Second Priority Representative. If, at any time, all or part of any payment with respect to any Second Priority Obligations previously made are rescinded for any reason whatsoever, each Junior Priority Secured Party will promptly pay over to the Second Priority Representative any payment received by it in respect of any such Shared Collateral and shall promptly turn any such Shared Collateral then held by it over to the Second Priority Representative, and the provisions set forth in this Agreement shall be reinstated as if such payment had not been made, until the payment and satisfaction in full all of such Second Priority Obligations.

4.2 Releases of Junior Priority Lien. (a) Upon (i) any sale or other disposition of Shared Collateral permitted pursuant to the terms of the Second Priority Documents that results in the release of the Second Priority Lien on any Shared Collateral (including any sale or other disposition pursuant to any Enforcement Action) or (ii) any other release of Shared Collateral from the Lien under the Second Priority Security Documents that is permitted pursuant to the terms of the Second Priority Documents, the Junior Priority Lien on such Shared Collateral (excluding any portion of the proceeds of such Shared Collateral remaining after the Second Priority Obligations Payment Date occurs) shall be automatically and unconditionally released with no further consent or action of any Person.

(b) The Junior Priority Representative shall promptly execute and deliver such release documents and instruments and shall take such further actions as the Second Priority Representative shall request to evidence any release of the Junior Priority Lien described in paragraph (a). The Junior Priority Representative hereby appoints the

Second Priority Representative and any officer or duly authorized person of the Second Priority Representative, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power of attorney in the place and stead of the Junior Priority Representative and in the name of the Junior Priority Representative or in the Second Priority Representative’s own name, from time to time, in the Second Priority Representative’s sole discretion, for the purposes of carrying out the terms of this Section 4.2, to take any and all appropriate action and to execute and deliver any and all documents and instruments as may be necessary or desirable to accomplish the purposes of this Section 4.2, including any financing statements, endorsements, assignments, releases or other documents or instruments of transfer (which appointment, being coupled with an interest, is irrevocable).

4.3 Inspection Rights and Insurance. (a) Any Second Priority Secured Party and its representatives and invitees may at any time inspect, repossess, remove and otherwise deal with the Shared Collateral, and the Second Priority Representative may advertise and conduct public auctions or private sales of the Shared Collateral, in each case without notice to, the involvement of or interference by any Junior Priority Secured Party or liability to any Junior Priority Secured Party.

(b) Until the Second Priority Obligations Payment Date has occurred, the Second Priority Representative will have the sole and exclusive right (i) to be named as additional insured and loss payee under any insurance policies maintained from time to time by any Grantor (except that the Junior Priority Representative shall have the right to be named as additional insured and loss payee so long as its second lien status is identified in a manner satisfactory to the Second Priority Representative), (ii) to adjust or settle any insurance policy or claim covering the Shared Collateral in the event of any loss thereunder and (iii) to approve any award granted in any condemnation or similar proceeding affecting the Shared Collateral.

4.4 Rights as Unsecured Creditors. Notwithstanding anything to the contrary in this Agreement, the Junior Priority Representative and the Junior Priority Secured Parties may exercise rights and remedies as unsecured creditors against any Grantor in respect of the Junior Priority Obligations in accordance with the terms of the Junior Priority Documents, including the acceleration of any Indebtedness or other obligations owing under the Junior Priority Documents or the demand for payment under the guarantee in respect thereof, in each case in accordance with the terms of the applicable Junior Priority Documents and applicable law and not otherwise inconsistent with the terms of this Agreement. Nothing in this Agreement shall prohibit the receipt by any Junior Priority Representative or any Junior Priority Secured Party of the required payments of interest and principal so long as such receipt is not the direct or indirect result of (a) the exercise by any Junior Priority Representative or any Junior Priority Secured Party of rights or remedies as a secured creditor in respect of Shared Collateral or other collateral or (b) the enforcement in contravention of this Agreement of any Lien in respect of Junior Priority Liens held by any of them. Nothing in this Agreement impairs or otherwise adversely affects any rights or remedies the Second Priority Representative or the Second Priority Secured Parties may have with respect to the Second Priority Collateral.

5.1 Filing of Motions. Until the Second Priority Obligations Payment Date has occurred, the Junior Priority Representative agrees on behalf of itself and the Junior Priority Secured Parties that no Junior Priority Secured Party shall, in or in connection with any Insolvency Proceeding, file any pleading or motion, take any position at any hearing or proceeding of any nature, or otherwise take any action whatsoever, in each case in respect of any of the Shared Collateral, including with respect to the determination of any Liens or claims (including the validity and enforceability thereof) held by the Second Priority Representative or any Second Priority Secured Party or the value of any claims of such parties under Section 506(a) of the Bankruptcy Code or otherwise; provided that (a) in any Insolvency Proceeding, the Junior Priority Representative may file a proof of claim or statement of interest with respect to the applicable Junior Priority Liens, (b) the Junior Priority Representative may take any such action (not adverse to the Second Priority Liens on the Shared Collateral securing the Second Priority Obligations, or the rights of either the Second Priority Representative or the Second Priority Secured Parties to exercise remedies in respect thereof) to the extent required to create, prove, perfect, preserve or protect (but not enforce) its rights in, and perfection and priority of its Liens on, the Shared Collateral, (c) in any Insolvency Proceeding, the Junior Priority Representative may file any necessary or responsive pleading in opposition to any motion, adversary proceeding or other pleading filed by any Person objecting to or otherwise seeking disallowance of the claim or Lien of such Junior Priority Representative or any Junior Priority Secured Party, (d) the Junior Priority Representative may file any pleadings, objections, motions or agreements which assert rights available to unsecured creditors arising under any Insolvency Proceeding or applicable non-bankruptcy law and (e) the Junior Priority Representative and each Junior Priority Secured Party may vote on any plan of reorganization in any Insolvency Proceedings; provided, however, that in the case of each of clauses (a), (b), (c), (d) and (e) above, such actions are permitted only to the extent such actions are not inconsistent with, and could not result in a resolution inconsistent with, the terms of this Agreement.

5.2 Financing Matters. If any Grantor becomes subject to any Insolvency Proceeding, and if the Second Priority Representative (acting at the direction of the requisite Second Priority Secured Parties) desires to permit the use of cash collateral or to permit any Grantor to obtain financing under Section 363 or Section 364 of Title 11 of the United States Code or any similar provision in any Bankruptcy Law (“DIP Financing”), then the Junior Priority Representative, for itself and on behalf of each applicable Junior Priority Secured Party, agrees that it will raise no objection to, and will not support any objection to, and will not otherwise contest such use of cash collateral or DIP Financing and will not request adequate protection or any other relief in connection therewith (except to the extent permitted by Section 5.4) and, to the extent the Liens securing the Second Priority Obligations are subordinated or pari passu with such DIP Financing, will subordinate the Liens in the Shared Collateral in favor of the Junior Priority Obligations to such DIP Financing (and all Obligations relating thereto) on the same basis as they are subordinated to the Second Priority Obligations. The Junior Priority Representative, for itself and on behalf of each Junior Priority Secured Party, agrees that, in the event of an Insolvency Proceeding, it will raise no objection to, and

will not support any objection to, and will not otherwise contest (a) any motion for relief from the automatic stay or from any injunction against foreclosure or enforcement in respect of Second Priority Obligations made by the Second Priority Representative or any Second Priority Secured Party, (b) any lawful exercise by the Second Priority Representative or any other Second Priority Secured Party of the right to credit bid any Second Priority Obligations at any sale in foreclosure of Second Priority Collateral, (c) any other request for judicial relief made in any court by the Second Priority Representative or any other Second Priority Secured Party relating to the lawful enforcement of any Second Priority Lien and (d) any order relating to a sale of assets of any Grantor for which the Second Priority Representative has consented that provides, to the extent the sale is to be free and clear of Liens, that the Liens securing the Second Priority Obligations and the Second Priority Obligations will attach to the proceeds of the sale on the same basis of priority as the existing Liens in accordance with this Agreement.

5.3 Relief From the Automatic Stay. The Junior Priority Representative agrees, on behalf of itself and the Junior Priority Secured Parties, that none of them will seek relief from the automatic stay or from any other stay in any Insolvency Proceeding or take any action in derogation thereof, in each case in respect of any Shared Collateral, without the prior written consent of the Second Priority Representative and the Applicable Authorized Representative.

5.4 Adequate Protection. The Junior Priority Representative, on behalf of itself and the Junior Priority Secured Parties, agrees that none of them shall object to, contest, or support any other Person objecting to or contesting (a) any request by the Second Priority Representative or the Second Priority Secured Parties for adequate protection or any adequate protection provided to the Second Priority Representative or the Second Priority Secured Parties, (b) any objection by the Second Priority Representative or any Second Priority Secured Parties to any motion, relief, action or proceeding based on a claim of a lack of adequate protection or (c) the payment of interest, fees, expenses, costs, charges or other amounts to the Second Priority Representative or any Second Priority Secured Party under Section 506(b) or 506(c) of the Bankruptcy Code or otherwise. Notwithstanding anything contained in this Section 5.4 and in Section 5.2(b) (but subject to all other provisions of this Agreement, including Sections 5.2(a) and 5.3), in any Insolvency Proceeding, (i) if the Second Priority Secured Parties (or any subset thereof) are granted adequate protection that includes additional collateral (with replacement Liens on such additional collateral) in connection with any DIP Financing or use of cash collateral, then in connection with any such DIP Financing or use of cash collateral the Junior Priority Representative, on behalf of itself and any of the Junior Priority Secured Parties, may seek or accept adequate protection consisting solely of a replacement Lien on the same additional collateral, subordinated to the Liens securing (x) such DIP Financing on the same terms as the Second Priority Liens are subordinated thereto (and such subordination will not alter in any manner the terms of this Agreement) and (y) the Second Priority Obligations on the same basis as the other Liens securing the Junior Priority Obligations are so subordinated to the Second Priority Obligations under this Agreement and (ii) in the event the Junior Priority Representative, on behalf of itself and the Junior Priority Secured Parties, seeks or accepts adequate

protection in accordance with clause (i) above in the form of additional collateral, then the Junior Priority Representative, on behalf of itself or any of the Junior Priority Secured Parties, agrees that the Second Priority Representative shall also be granted a senior Lien on such additional collateral as security for the Second Priority Obligations and any such DIP Financing and that any Lien on such additional collateral securing the Junior Priority Obligations shall be subordinated to (A) the Liens on such collateral securing the Second Priority Obligations and any other Liens granted to the Second Priority Secured Parties as adequate protection on the same terms that the Liens securing the Junior Priority Obligations are subordinated to such Second Priority Obligations under this Agreement and (B) (x) the Liens on such collateral securing such DIP Financing (and all obligations relating thereto), (y) any “carve-out” agreed to by the Second Priority Representative or the Second Priority Secured Parties and (z) in the case of any Insolvency Proceeding outside the United States, any administrative or other charges granted in any Insolvency Proceeding that are similar in nature to a “carve-out” and agreed to by the Second Priority Representative or the Second Priority Secured Parties, in the case of each of clauses (B) (x), (y) and (z), with such subordination to be on the same terms as the Liens securing the Second Priority Obligations are subordinated thereto (and such subordination will not alter in any manner the terms of this Agreement). The Junior Priority Representative, on behalf of itself and the Junior Priority Secured Parties, agrees that except as expressly set forth in this Section 5.4, and except for adequate protection in the form of access to information to the extent such access is also made available to the Second Priority Representative on behalf of itself and the Second Priority Secured Parties, none of them shall seek or accept adequate protection without the prior written consent of the Second Priority Representative.

5.5 Avoidance Issues. If any Second Priority Secured Party is required in any Insolvency Proceeding or otherwise to disgorge, turn over or otherwise pay to the bankruptcy trustee or the estate of any Grantor, because such amount was avoided or ordered to be paid or disgorged for any reason, including because it was found to be a fraudulent or preferential transfer, any amount (a “Recovery”), whether received as proceeds of security, enforcement of any right of set-off or otherwise, then the Second Priority Obligations shall be reinstated to the extent of such Recovery and deemed to be outstanding as if such payment had not occurred and the Second Priority Obligations Payment Date, if it shall otherwise have occurred, shall be deemed not to have occurred. If this Agreement shall have been terminated prior to such Recovery, this Agreement shall be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair or otherwise affect the obligations of the parties hereto. The Junior Priority Secured Parties agree that none of them shall be entitled to benefit from any avoidance action affecting or otherwise relating to any distribution or allocation made in accordance with this Agreement, whether by preference or otherwise, it being understood and agreed that the benefit of such avoidance action otherwise allocable to them shall instead be allocated and turned over for application in accordance with the priorities set forth in this Agreement.

5.6 Asset Dispositions in an Insolvency Proceeding. Neither the Junior Priority Representative nor any Junior Priority Secured Party shall, in an Insolvency Proceeding or otherwise, oppose any sale or other disposition of any assets of any

Grantor that is supported by the Second Priority Secured Parties, and the Junior Priority Representative and each Junior Priority Secured Party will be deemed to have consented under Section 363 of the Bankruptcy Code (and otherwise) to any such sale or other disposition of assets supported by the Second Priority Secured Parties and to have released their Liens on such assets; provided, to the extent such sale is to be free and clear of Liens, that the Liens securing the Second Priority Obligations and the Junior Priority Obligations will attach to the proceeds of the sale on the same basis of priority as the Liens released on the assets sold.

5.7 Separate Grants of Security and Separate Classification. Each Junior Priority Secured Party acknowledges and agrees that (a) the grants of Liens pursuant to the Second Priority Security Documents and the Junior Priority Security Documents constitute two separate and distinct grants of Liens and (b) because of, among other things, their differing rights in the Shared Collateral, the Junior Priority Obligations are fundamentally different from the Second Priority Obligations and must be separately classified in any plan of reorganization proposed or adopted in an Insolvency Proceeding. To further effectuate the intent of the parties as provided in the immediately preceding sentence, if it is held that the claims of the Second Priority Secured Parties and Junior Priority Secured Parties in respect of the Shared Collateral constitute only one class of secured claims (rather than separate classes of senior and junior secured claims), then the Junior Priority Secured Parties hereby acknowledge and agree that all distributions shall be made as if there were separate classes of senior and junior secured claims against the Grantors in respect of the Shared Collateral (with the effect being that, to the extent that the aggregate value of the Shared Collateral is sufficient (for this purpose ignoring all claims held by the Junior Priority Secured Parties), the Second Priority Secured Parties shall be entitled to receive, in addition to amounts distributed to them in respect of principal, pre-petition interest and other claims, all amounts owing in respect of Post-Petition Interest before any distribution is made in respect of the claims held by the Junior Priority Secured Parties, with the Junior Priority Secured Parties hereby acknowledging and agreeing to turn over to the Second Priority Secured Parties amounts otherwise received or receivable by them to the extent necessary to effectuate the intent of this sentence, even if such turnover has the effect of reducing the claim or recovery of the Junior Priority Secured Parties), and that, until turned over to the Second Priority Secured Parties, such amounts will be held in trust for the Second Priority Secured Parties.

5.8 No Waivers of Rights of Second Priority Secured Parties. Nothing contained herein shall prohibit or in any way limit the Second Priority Representative or any Second Priority Secured Party from objecting in any Insolvency Proceeding or otherwise to any action taken by any Junior Priority Secured Party not expressly permitted hereunder, including the seeking by any Junior Priority Secured Party of adequate protection (except as provided in Section 5.4) or the asserting by any Junior Priority Secured Party of any of its rights and remedies under the Junior Priority Documents or otherwise.

5.9 Plans of Reorganization. No Junior Priority Secured Party shall support or vote in favor of any plan of reorganization (and each shall be deemed to have voted to

reject any plan of reorganization) unless such plan (a) pays off, in cash in full, all Second Priority Obligations or (b) is accepted by the class of holders of Second Priority Obligations voting thereon.

5.11 Effectiveness in Insolvency Proceedings. This Agreement, which the parties hereto expressly acknowledge is a “subordination agreement” under section 510(a) of the Bankruptcy Code, shall be effective before, during and after the commencement of an Insolvency Proceeding. All references to any Grantor herein shall apply to any trustee for such Person and such Person as debtor in possession. The relative rights as to the Shared Collateral and other collateral and proceeds thereof shall continue after the filing thereof on the same basis as prior to the date of the petition, subject to any court order approving the financing of, or use of cash collateral by, any such Person.

5.12 Reorganization Securities. If, in any Insolvency Proceeding, debt obligations of the reorganized debtor secured by Liens upon any property of the reorganized debtor (“Reorganization Securities”) are distributed, pursuant to a plan of reorganization or similar dispositive restructuring plan, on account of the Junior Priority Obligations, then the provisions of this Agreement will survive the distribution of such debt obligations pursuant to such plan and will apply with like effect to the Liens securing such debt obligations. In no event shall the Junior Priority Secured Parties be required to turn over to the Second Priority Representative or any Second Priority Secured Party any Reorganization Securities to the extent the same are subject to this Section 5.12.

5.13 Post-Petition Claims. None of the Junior Priority Representative or any Junior Priority Secured Party shall oppose or seek to challenge any claim by the Second Priority Representative or any Second Priority Secured Party for allowance in any Insolvency Proceeding of Second Priority Obligations consisting of Post-Petition Interest or indemnities to the extent of the value of the Liens in favor of the Second Priority Representative and the Second Priority Secured Parties, without regard to the existence of the Liens of the Junior Priority Representative on behalf of the Junior Priority Secured Parties on the Shared Collateral.

5.14 Waivers. Until the Second Priority Obligations Payment Date, the Junior Priority Representative, on behalf of itself and each Junior Priority Secured Party, agrees that (a) it will not assert or enforce any claim under Section 506(c) of the Bankruptcy Code senior to or on a parity with the Liens securing the Second Priority Obligations for costs or expenses of preserving or disposing of any Shared Collateral or other collateral and (b) waives any claim it may now or hereafter have arising out of the election by any Second Priority Secured Party of the application of Section 1111(b)(2) of the Bankruptcy Code.

(a) Each Grantor and the Junior Priority Representative, on behalf of itself and the Junior Priority Secured Parties, agrees that it shall not at any time execute or deliver any amendment or other modification to any of the Junior Priority Documents inconsistent with or in violation of this Agreement.

(b) Each Grantor and the Second Priority Representative, on behalf of itself and the Second Priority Secured Parties, agrees that it shall not at any time execute or deliver any amendment or other modification to any of the Second Priority Documents inconsistent with or in violation of this Agreement.

(c) In the event the Second Priority Representative enters into any amendment, waiver or consent in respect of any of the Second Priority Security Documents for the purpose of adding to, or deleting from, or waiving or consenting to any departures from any provisions of, any Second Priority Security Document or changing in any manner the rights of any parties thereunder, then such amendment, waiver or consent shall apply automatically to any comparable provision of the Comparable Junior Priority Security Document without the consent of or action by any Junior Priority Secured Party (with all such amendments, waivers and modifications subject to the terms hereof); provided that (other than with respect to amendments, modifications or waivers that secure additional extensions of credit and add additional secured creditors and do not violate the express provisions of the Junior Priority Agreements), (i) no such amendment, waiver or consent shall have the effect of removing assets subject to the Lien of any Junior Priority Security Document, except to the extent that a release of such Lien is permitted by Section 4.2, (ii) any such amendment, waiver or consent that materially and adversely affects the rights of the Junior Priority Secured Parties and does not affect the Second Priority Secured Parties in a like or similar manner shall not apply to the Junior Priority Security Documents without the consent of the Junior Priority Representative and (iii) notice of such amendment, waiver or consent shall be given to the Junior Priority Representative no later than 15 days after its effectiveness; provided that the failure to give such notice shall not affect the effectiveness and validity thereof.

7.1 Reliance. The Second Priority Documents are deemed to have been executed and delivered, and all issuances of debt or other extensions of credit thereunder are deemed to have been made or incurred, in reliance upon this Agreement. The Junior Priority Representative, on behalf of itself and the Junior Priority Secured Parties, expressly waives all notice of the acceptance of and reliance on this Agreement by the Second Priority Secured Parties. The Junior Priority Documents are deemed to have been executed and delivered, and all issuances of debt and other extensions of credit thereunder are deemed to have been made or incurred, in reliance upon this Agreement. The Second Priority Representative expressly waives, on behalf of itself and all the Second Priority Secured Parties, all notices of the acceptance of and reliance by the Junior Priority Representative and the Junior Priority Secured Parties.

7.2 No Warranties or Liability. The Junior Priority Representative and the Second Priority Representative acknowledge and agree that neither has made any representation or warranty with respect to the execution, validity, legality, completeness, collectibility or enforceability of any other Second Priority Document or any Junior Priority Document. Except as otherwise provided in this Agreement, the Junior Priority Representative and the Second Priority Representative will be entitled to manage and supervise their respective extensions of credit to any Grantor in accordance with law and their usual practices, modified from time to time as they deem appropriate.

7.3 No Waivers. No right or benefit of any party hereunder shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of such party or any other party hereto or by any noncompliance by any Grantor with the terms and conditions of any of the Second Priority Documents or the Junior Priority Documents.

8.1 Second Priority Obligations Unconditional. All rights and interests of the Second Priority Secured Parties hereunder, and all agreements and obligations of the Junior Priority Secured Parties (and, to the extent applicable, the Grantors) hereunder, shall remain in full force and effect irrespective of:

(b) any change in the time, place or manner of payment of, or in any other term of, all or any portion of the Second Priority Obligations, or any amendment, waiver or other modification, whether by course of conduct or otherwise, or any refinancing, replacement, refunding or restatement of any Second Priority Document;

(c) prior to the Second Priority Obligations Payment Date, any exchange, release, voiding, avoidance or non-perfection of any security interest in any Shared Collateral or any other collateral, or any release, amendment, waiver or other modification, whether by course of conduct or otherwise, or any refinancing, replacement, refunding or restatement of all or any portion of the Second Priority Obligations or any guarantee or guaranty thereof; or

(d) any other circumstances that otherwise might constitute a defense available to, or a discharge of, any Grantor in respect of the Second Priority Obligations, or of any Junior Priority Secured Party or any Grantor, to the extent applicable, in respect of this Agreement.

8.2 Junior Priority Obligations Unconditional. All rights and interests of the Junior Priority Secured Parties hereunder, and all agreements and obligations of the Second Priority Secured Parties (and, to the extent applicable, the Grantors) hereunder, shall remain in full force and effect irrespective of:

(b) any change in the time, place or manner of payment of, or in any other term of, all or any portion of the Junior Priority Obligations, or any amendment, waiver or other modification, whether by course of conduct or otherwise, or any refinancing, replacement, refunding or restatement of any Junior Priority Document;

(d) any other circumstances that otherwise might constitute a defense available to, or a discharge of, any Grantor in respect of the Junior Priority Obligations, or of any Second Priority Secured Party or any Grantor, to the extent applicable, in respect of this Agreement.

9.1 Conflicts. In the event of any conflict between the provisions of this Agreement and the provisions of any Second Priority Document or any Junior Priority Document, the provisions of this Agreement shall govern.

9.2 Continuing Nature of Provisions. This Agreement shall continue to be effective, and shall not be revocable by any party hereto, until the Second Priority Obligations Payment Date shall have occurred, subject to Section 5.5. This is a continuing agreement and the Second Priority Secured Parties and the Junior Priority Secured Parties may continue, at any time and without notice to the other parties hereto, to extend credit and other financial accommodations, lend monies and provide Indebtedness to, or for the benefit of, any Grantor on the faith hereof.

9.3 Amendments; Waivers. (a) No amendment or modification of any of the provisions of this Agreement shall be effective unless the same shall be in writing and signed by the Second Priority Representative and the Junior Priority Representative, and, in the case of amendments or modifications of Sections 3.5, 3.6, 9.5 or 9.6 that directly affect the rights or obligations of any Grantor, such Grantor.

(b) At the request of the Issuer, the Second Priority Representative and the Junior Priority Representative agree to enter into any amendment to this Agreement or any new intercreditor agreement in order to (1) facilitate additional Indebtedness or other obligations (“Additional Debt”) of any of the Grantors becoming Second Priority Obligations or Junior Priority Obligations to the extent such Obligations are permitted by the Second Priority Agreement and the Junior Priority Agreement, with the Lien priority contemplated by such amendment (provided that such Additional Debt is permitted to be incurred by the Second Priority Agreement and Junior Priority Agreement then extant, and is permitted by said agreements to be subject to the provisions of this Agreement as Second Priority Obligations or Junior Priority Obligations, as applicable), (2) document

the relationship among Junior Priority Secured Parties pursuant to different Junior Priority Agreements, including, to the extent permitted under each extant Second Priority Agreement and Junior Priority Agreement, the treatment of the Liens securing Junior Priority Obligations under any Additional Junior Priority Agreement as equal and ratable with the Liens securing the Junior Priority Obligations under the Existing Junior Priority Agreement or any other Additional Junior Priority Agreement and (3) document the relationship between the Second Priority Secured Parties and the Junior Priority Secured Parties in case any then existing Second Priority Agreement or Junior Priority Agreement is refinanced or replaced or the Second Priority Representative or the Junior Priority Representative is replaced; provided that (i) the Issuer shall have delivered an Officers’ Certificate (A) designating such other Additional Debt and the aggregate principal amount or face amount thereof and (B) representing that such designation complies with the terms of the Second Priority Documents and the Junior Priority Documents, as applicable, and (ii) in any case, the terms of such amendment or new agreement will contain terms substantially the same as the terms contained in this Agreement.

9.4 Information Concerning Financial Condition of the Grantors. The Junior Priority Representative and the Second Priority Representative hereby agree that no party shall have any duty to advise any other party of information known to it regarding the financial condition of the Grantors or any such circumstances. In the event the Junior Priority Representative or the Second Priority Representative, in its sole discretion, undertakes at any time or from time to time to provide any information to any other party to this Agreement, it shall be under no obligation (a) to provide any such information to such other party or any other party on any subsequent occasion, (b) to undertake any investigation or (c) to disclose any other information.

9.5 Governing Law. This Agreement shall be construed in accordance with and governed by the law of the State of New York, except as otherwise required by mandatory provisions of law and except to the extent that remedies provided by the laws of any jurisdiction other than the State of New York are governed by the laws of such jurisdiction.

9.6 Submission to Jurisdiction. (a) Each Second Priority Secured Party, each Junior Priority Secured Party and each Grantor hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment pursuant to any such action or proceeding, and each such party hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each such party agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that any Second Priority Secured Party or Junior Priority Secured Party may otherwise have to bring any action or proceeding against any Grantor or its properties in the courts of any jurisdiction.

(b) Each Second Priority Secured Party, each Junior Priority Secured Party and each Grantor hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, (i) any objection it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (a) of this Section and (ii) the defense of an inconvenient forum to the maintenance of such action or proceeding.

(c) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.7. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

9.7 Notices. Unless otherwise specifically provided herein, any notice or other communication herein required or permitted to be given shall be in writing and may be personally served, telecopied or sent by overnight express courier service or United States mail and shall be deemed to have been given when delivered in person or by courier service, upon receipt of a telecopy or five days after deposit in the United States mail (certified, with postage prepaid and properly addressed). For the purposes hereof, the address of (a) the Issuer, the Collateral Agent, the Trustee and the Junior Priority Representative (until notice of a change thereof is delivered as provided in this Section) shall be as set forth in the Second Priority Agreement or the Junior Priority Agreement, as applicable and (b) any other party shall be in care of the Issuer as so set forth in clause (a), or, as to each party, at such other address as may be designated by such party in a written notice to all of the other parties.

9.8 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of each of the parties hereto and each of the Second Priority Secured Parties and Junior Priority Secured Parties and their respective successors and assigns, and nothing herein is intended, or shall be construed, to give any other Person any right, remedy or claim under, to or in respect of this Agreement or any Shared Collateral.

9.9 Headings. Section headings used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

9.10 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

9.11 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic transmission shall be effective as delivery of a

manually executed counterpart of this Agreement. This Agreement shall become effective when it shall have been executed by each party hereto.

9.12 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT AND FOR ANY COUNTERCLAIM THEREIN.

9.13 Additional Grantors. The Issuer shall cause each Person that becomes a Grantor after the date hereof (other than any such Grantor that does not grant any Liens to secure any of the Junior Priority Obligations, until such time as such Grantor does grant any such Liens) to become a party to this Agreement by executing and delivering a supplement to this Agreement in form and substance reasonably satisfactory to the Second Priority Representative and the Junior Priority Representative.

9.14 Representatives. In connection with its execution of this Agreement and its actions hereunder, each of the Second Priority Representative and the Junior Priority Representative shall be entitled to all rights, privileges, benefits, protections, immunities and indemnities provided to it under the Second Priority Documents and under the Junior Priority Documents, respectively.

9.15 Subrogation. The Junior Priority Representative, for itself and on behalf of the Junior Priority Secured Parties, hereby waives any rights of subrogation it or they may acquire as a result of any payment hereunder until the Second Priority Obligations Payment Date has occurred; provided, however, that, as between the Grantors, on the one hand, and the Junior Priority Secured Parties, on the other hand, any such payment that is paid over to the Second Priority Representative pursuant to this Agreement shall be deemed not to reduce any of the Junior Priority Obligations unless and until (and then only to the extent that) the Second Priority Obligations Payment Date has occurred and the Second Priority Representative delivers any such payment to the Junior Priority Representative.

9.16. Indenture. In addition to the foregoing rights, in acting hereunder and by virtue of this Agreement, the Second Priority Representative shall have all of the rights, protections and immunities granted to it under the Indenture, all of which are incorporated by reference herein.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date first written above.
