ARTICLE 2

THE SECURITIES

SECTION 2.01. Amount of Securities .

(a) Subject to the terms and conditions set forth in this Section 2.01, the aggregate principal amount of Securities that may be authenticated and delivered under this Indenture is limited to $120,000,000.

(b) On the Issue Date, the Issuer shall issue and deliver, in accordance with this Article 2, Original Securities in an aggregate principal amount of $84,000,000.

(c) As long as no Event of Default has occurred and is continuing, if the Additional Securities Triggering Event occurs, then the Issuer shall issue and deliver (subject to receiving agreed-upon consideration therefor), in accordance with this Section 2.01(c), within 10 Business Days of the Additional Securities Triggering Event, upon five Business Days’ written notice to the Trustee (which five Business Day period may, for the avoidance of doubt, be concurrent with such 10 Business Day period), accompanied by an Officers’ Certificate certifying as to the occurrence of and date of the Additional Securities Triggering Event (but, in any case, not during the period between the day immediately after the relevant Record Date immediately preceding the next related Payment Date and such Payment Date, unless the entire such 10 Business Day period following the Additional Securities Triggering Event is within such period, in which case, on the Business Day immediately following such Payment Date) and subject to the substantially concurrent receipt of payment therefor, additional Securities in an aggregate principal amount of $36,000,000 (“Additional Securities”). Such Additional Securities shall have the same terms as the Original Securities, except that the issuance price, the issuance date and the initial Payment Date may vary. If the Issuer determines that any such Additional Securities are issued as part of a “qualified reopening” for U.S. federal income tax purposes, such Additional Securities will have the same CUSIP number as the Original Securities and for U.S. federal income tax purposes will have the same issue date and issue price as the Original Securities. If the Issuer determines that any such Additional Securities are not issued as part of a “qualified reopening” for U.S. federal income tax purposes, such Additional Securities will be required to have a CUSIP number that is different than the CUSIP number of the Original Securities.

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

SECTION 2.02. Form and Dating . Provisions relating to the Securities are set forth in Appendix A hereto, which is hereby incorporated in and expressly made a part of this

41

Indenture. The Securities and the Trustee’s certificate of authentication shall each be substantially in the form of Exhibit A hereto, which is hereby incorporated in and expressly made a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Issuer or any Guarantor is subject, if any, or usage ( provided that any such notation, legend or endorsement is in a form acceptable to the Issuer). Each Security shall be dated the date of its authentication. The Securities shall be issuable only in registered form, without interest coupons, and in minimum denominations of $50,000 and any integral multiple of $1,000 in excess thereof.

SECTION 2.03. Execution and Authentication . The Trustee shall authenticate and make available for delivery upon a written order of the Issuer signed by one Officer (a) Original Securities for original issue on the Issue Date in an aggregate principal amount of $84,000,000 and (b) subject to the terms and conditions set forth in Section 2.01(c), Additional Securities for original issue after the Additional Securities Triggering Event in an aggregate principal amount of $36,000,000. Such order shall specify the amount of the Securities to be authenticated, the form in which the Securities are to be authenticated and the date on which the original issue of Securities is to be authenticated.

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

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

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

The Trustee may appoint one or more authenticating agents reasonably acceptable to the Issuer to authenticate the Securities. Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

SECTION 2.04. Registrar and Paying Agent .

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

42

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

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

SECTION 2.05. Paying Agent to Hold Money in Trust . On or prior to each due date of the principal of and interest on any Security, the Issuer shall deposit with each Paying Agent (or if the Issuer or a Wholly Owned Restricted Subsidiary is acting as Paying Agent, segregate and hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal and interest when so becoming due. The Issuer shall require each Paying Agent (other than the Trustee) to agree in writing that a Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by a Paying Agent for the payment of principal of and interest on the Securities, and shall notify the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. If the Issuer or a Wholly Owned Restricted Subsidiary of the Issuer acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it in trust for the benefit of the Persons entitled thereto. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Section 2.05, a Paying Agent shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee will automatically serve as the Paying Agent if not otherwise so acting.

SECTION 2.06. Holder Lists . The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Issuer shall furnish, or cause the Registrar to furnish, to the Trustee, in writing at least five Business Days before each Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders. The Issuer shall also maintain a copy of such list of the names and addresses of Holders at its registered office.

43

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

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

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

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

SECTION 2.08. Replacement Securities . If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) satisfies the Issuer or the Trustee within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Issuer or the Trustee prior to the Security being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Issuer and the Trustee. If required by the Trustee or the Issuer, such Holder shall furnish an indemnity bond sufficient in the judgment of the Trustee to protect the Trustee, the Paying

44

Agent and the Registrar (if the Registrar also serves as the Paying Agent) and of the Issuer to protect the Issuer, each Guarantor, the Paying Agent and the Registrar (if the Trustee is not serving in the role of Paying Agent or Registrar, as the case may be) from any loss that any of them may suffer if a Security is replaced. The Issuer and the Trustee may charge the Holder for their expenses in replacing a Security (including attorneys’ fees and disbursements in replacing such Security). In the event any such mutilated, lost, destroyed or wrongfully taken Security has become or is about to become due and payable, the Issuer in its discretion may pay such Security instead of issuing a new Security in replacement thereof.

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

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

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

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

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

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

45

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

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

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

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

SECTION 2.15. Statement to Holders . After the end of each calendar year but not later than the latest date permitted by applicable law, the Trustee shall furnish to each Person

46

who at any time during such calendar year was a Holder a statement (for example, a Form 1099 or any other means required by applicable law) prepared by the Trustee as may be required pursuant to the then-applicable regulations under the Code.

ARTICLE 3

REDEMPTION

SECTION 3.01. Redemption . The Securities may be redeemed by the Issuer at its option, in whole, or from time to time in part, on any Business Day specified by the Issuer, subject to the conditions and at the redemption prices set forth in Paragraph 5 of the form of Security set forth in Exhibit A hereto, which is hereby incorporated by reference and made a part of this Indenture, together with accrued and unpaid interest to the redemption date. The Securities may also be redeemed by the Issuer in whole, subject to the conditions and at the redemption prices set forth in Sections 3.09 and 4.08(k), together with accrued and unpaid interest to the redemption date.

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

SECTION 3.04. Selection of Securities to Be Redeemed . In the case of any partial redemption, and if the Securities are Global Securities held by the Depository, the Depository will select the Securities to be redeemed in accordance with its operational arrangements. If the Securities are not Global Securities held by the Depository, selection of the Securities for redemption will be made by the Trustee on a pro rata basis to the extent practicable or such other method the Trustee deems fair and appropriate; provided that no Securities of $1,000 or less shall be redeemed in part. The Trustee shall make the selection from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities that have denominations larger than $1,000. Securities and portions of them the Trustee selects shall be in amounts of $1,000 or any integral multiple of $1,000 in

47

excess thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Issuer promptly of the Securities or portions of Securities to be redeemed.

SECTION 3.05. Notice of Optional Redemption .

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

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

(i) the redemption date;

(ii) the redemption price (or manner of calculation thereof if not then known) and the amount of accrued interest to the redemption date;

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

(iv) that Securities called for redemption must be surrendered to the Paying Agent to collect the redemption price, plus accrued interest;

(v) that all outstanding Securities are to be redeemed or, if fewer than all the outstanding Securities are to be redeemed, the certificate numbers and principal amounts of the particular Securities to be redeemed, the aggregate principal amount of Securities to be redeemed and the aggregate principal amount of Securities to be outstanding after such partial redemption;

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

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

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

(b) At the Issuer’s request, the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense. In such event, the Issuer shall provide the Trustee a notice containing the information required by this Section 3.05 at least five Business Days (unless the Trustee consents to a shorter period) prior to the date such notice is to be provided to Holders and such notice may not be canceled but may be subject to such conditions precedent as shall be set forth in such notice.

48

SECTION 3.06. Effect of Notice of Redemption . Once written notice of redemption is provided in accordance with Section 3.05, 3.09 or 4.08(k), Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, subject to the satisfaction or waiver of any conditions precedent in the notice of redemption. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued and unpaid interest, to, but not including, the redemption date; provided , however , that if the redemption date is after a Record Date and on or prior to the related Payment Date, the accrued and unpaid interest shall be payable to the Holder of the redeemed Securities registered on such Record Date. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

SECTION 3.07. Deposit of Redemption Price . With respect to any Securities, prior to 10:00 a.m., New York City time, on the redemption date, the Issuer shall deposit with the Paying Agent (or, if the Issuer or a Wholly Owned Restricted Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued and unpaid interest on all Securities or portions thereof to be redeemed on that date other than Securities or portions of Securities called for redemption that have been delivered by the Issuer to the Trustee for cancellation; provided that the Issuer has provided an Officers’ Certificate to the Trustee stating that all conditions precedent (if any) to which such redemption has been made subject pursuant to Section 3.05(b) have been satisfied. On and after the redemption date, interest shall cease to accrue on Securities or portions thereof called for redemption so long as the Issuer has deposited with the Paying Agent funds sufficient to pay the principal of, plus accrued and unpaid interest on, the Securities to be redeemed, unless the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, provided that the Issuer has provided an Officers’ Certificate to the Trustee stating that all conditions precedent (if any) to which such redemption has been made subject have been satisfied or waived.

SECTION 3.08. Securities Redeemed in Part . Upon surrender of a Security that is redeemed in part, the Issuer shall execute and the Trustee shall authenticate for the Holder (at the Issuer’s expense) a new Security equal in principal amount to the unredeemed portion of the Security surrendered.

The Issuer may redeem the Securities, in whole but not in part, at its discretion, on any Business Day specified by the Issuer, upon providing not less than 30 nor more than 60 days’ prior written notice to the Trustee, at a redemption price equal to 100% of the aggregate principal amount thereof, together with accrued and unpaid interest thereon, if any, to, but excluding, the redemption date, and all Additional Amounts or Additional Interest (if any) that otherwise would be payable, if, on the next date on which any amount would be payable in respect of the Securities, the Issuer would be required to pay Additional Amounts or Additional Interest, and the Issuer cannot avoid any such payment obligation by taking reasonable measures available to it, as a result of:

(a) any amendment to, or change in, the laws or any regulations or rulings promulgated thereunder of a Relevant Taxing Jurisdiction that is officially announced and becomes effective after the Issue Date (or, if the applicable Relevant Taxing Jurisdiction became a Relevant Taxing Jurisdiction on a date after the Issue Date, such later date); or

(b) any amendment to, or change in, an official interpretation or application regarding such laws, regulations or rulings, including by virtue of a holding, judgment or order by a court of competent jurisdiction that is officially announced and becomes effective after the Issue Date (or, if the applicable Relevant Taxing Jurisdiction became a Relevant Taxing Jurisdiction on a date after the Issue Date, such later date).

The Issuer will not give any such notice of redemption earlier than 90 days prior to the earliest date on which the Issuer would be obligated to pay such Additional Amounts or Additional Interest were a payment in respect of the Securities then due and payable, and, at the time such notice is given, the obligation to pay Additional Amounts or Additional Interest must remain in effect.

Prior to the provision of any written notice of redemption of the Securities, the Issuer will deliver to the Trustee an Officers’ Certificate stating that the Issuer cannot avoid any obligation to pay Additional Amounts or Additional Interest by taking reasonable measures available to it.

SECTION 4.01. Payment of Securities .

(a) The Issuer 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. An installment of principal or interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds as of 12:00 noon New York City time money sufficient to pay all principal and interest then due and the Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture. The Issuer shall pay interest on overdue principal at the rate specified therefor in the Securities, and the Issuer shall pay interest on overdue installments of interest at the same rate borne by the Securities to the extent lawful.

50

(b) On each Payment Date, commencing April 15, 2019, or on the succeeding Business Day if any such date is not a Business Day, the Issuer shall pay an installment of principal of the Original Securities (subject to adjustment in accordance with the second following paragraph) in an amount set forth below corresponding to such Payment Date:

In addition, in the event that any Additional Securities are issued after the Issue Date in accordance with Section 2.01(c), on each Payment Date subsequent thereto, or on the succeeding Business Day if any such date is not a Business Day, the Issuer shall pay an installment of principal of such Additional Securities (subject to adjustment as described in the following paragraph) in an amount equal to the amount obtained by multiplying the principal amount of such Additional Securities outstanding immediately prior to such payment by a fraction of which the numerator shall be the amount of the installment of principal of the Original Securities corresponding to such Payment Date (as it may have been previously reduced in accordance with the following paragraph) and the denominator shall be the aggregate unpaid outstanding principal balance of the Original Securities immediately prior to such payment.

In the event that there shall have been any partial redemption or purchase of the Securities pursuant to Article 3 or Section 4.06 or 4.08, each principal installment amount set forth above (as it may have been previously reduced in accordance with this paragraph) subsequent to such partial redemption or purchase shall be reduced by an amount equal to the amount obtained by multiplying such principal installment amount as in effect immediately prior to such partial redemption or purchase by a fraction of which the numerator shall be the aggregate principal amount of Securities redeemed or purchased pursuant to such partial redemption or purchase and the denominator shall be the aggregate unpaid outstanding principal balance of the Securities immediately prior to such partial redemption or purchase. Any such reduction shall be made on a pro rata basis, as nearly as practicable, among the Holders of the Securities (subject, however, to the applicable procedures of DTC).

(c) All payments made by or on behalf of the Issuer or any Guarantor (including any successor entity) (each, a “Payor”) in respect of the Securities or with respect to any Guarantee, as applicable, will be made free and clear of and without withholding or deduction for, or on account of, any Taxes unless the withholding or deduction of such Taxes is then required by law. If any deduction or withholding for, or on account of, any Taxes (subject to Section 4.01(d)) imposed or levied by or on behalf of a Relevant Taxing Jurisdiction, will at any time be required by law to be made from any payments made by or on behalf of the relevant Payor or paying agent with respect to any Security or any Guarantee, as applicable, including payments of principal, redemption price, interest or premium, if any, such Payor will pay (together with such payments) such additional amounts (the “Additional

51

Amounts”) as may be necessary in order that the net amounts received by the Holder in respect of such payments, after such withholding or deduction (including any such deduction or withholding from such Additional Amounts), will not be less than the amounts which would have been received by the Holder in respect of such payments on any such Security or Guarantee, as applicable, in the absence of such withholding or deduction; provided, however, that no such Additional Amounts will be payable for or on account of:

(i) any Taxes that would not have been so imposed but for the existence of any present or former connection between the relevant Holder or beneficial owner of a Security and a Relevant Taxing Jurisdiction (it being understood that a Relevant Taxing Jurisdiction is to be determined as though a payment with respect to the Securities were made on the Issue Date) but excluding, in each case, any connection arising solely from the acquisition, ownership or holding of such Security or the receipt of any payment or the exercise or enforcement of rights under such Security, this Indenture, a Guarantee, the Intercreditor Agreement, any additional intercreditor agreement or a Security Document;

(ii) any Tax that is imposed or withheld by reason of the failure by the Holder or the beneficial owner of such Security to comply with a reasonable written request of such Payor addressed to the Holder or the beneficial owner, after reasonable notice (at least 30 days before any such withholding or deduction would be payable), to provide certification, information, documents or other evidence concerning the nationality, residence or identity of the Holder or such beneficial owner or to make any declaration or similar claim or satisfy any other reporting requirement relating to such matters that is required by a statute, treaty, regulation or administrative practice of the Relevant Taxing Jurisdiction as a precondition to exemption from, or reduction in the rate of deduction of, all or part of such Tax but only to the extent the Holder or such beneficial owner is legally entitled to provide such certification or documentation;

(iii) any Taxes, to the extent that such Taxes were imposed or withheld as a result of the presentation of such Security for payment (where Securities are in the form of definitive registered notes and presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder (except to the extent that the Holder would have been entitled to Additional Amounts had such Security been presented on the last day of such 30-day period);

(iv) any Taxes that are payable otherwise than by deduction or withholding from a payment under or with respect to such Security or any Guarantee;

(v) any estate, inheritance, gift, sales, excise, transfer, personal property or similar tax, assessment or other governmental charge;

52

(vi) any tax imposed by reason of the Holder’s or beneficial owner’s past or present status (or the past or present status of a fiduciary, settlor, beneficiary, member or shareholder of, or possessor of a power over, such Holder or beneficial owner, if such Holder or beneficial owner is an estate, a trust, a partnership or a corporation) as a personal holding company, private foundation or other tax exempt organization, passive foreign investment company, controlled foreign corporation with respect to the United States, bank, or as a corporation that accumulates earnings to avoid U.S. federal income tax; or

(vii) any combination of items (i) through (vi) above.

Notwithstanding anything to the contrary herein, the Issuer and the Guarantors shall be permitted to withhold or deduct any amounts required by FATCA and none of the Issuer, the Guarantors or any other person shall be required to pay any additional amounts with respect to any FATCA withholding or deduction imposed on or with respect to any Security.

Each Payor will (i) make any required withholding or deduction and (ii) remit the full amount deducted or withheld to the Relevant Taxing Jurisdiction in accordance with applicable law. Each Payor will provide certified copies of tax receipts evidencing the payment of any Taxes so deducted or withheld to each Relevant Taxing Jurisdiction imposing such Taxes, or if such tax receipts are not available, certified copies of other reasonable evidence of such payments as soon as reasonably practicable to the Trustee. Such copies shall be made available to the holders upon reasonable request and will be made available at the offices of the relevant paying agent.

If any Payor is obligated to pay Additional Amounts under or with respect to any payment made on any Security or any Guarantee, at least 30 days prior to the date of such payment, such Payor will deliver to the Trustee an Officers’ Certificate stating the fact that Additional Amounts will be payable and the amount estimated to be so payable and such other information necessary to enable the paying agent to pay Additional Amounts to holders on the relevant payment date (unless such obligation to pay Additional Amounts arises less than 45 days prior to the relevant payment date, in which case such Payor may deliver such Officers’ Certificate as promptly as practicable thereafter). The Trustee shall be entitled to rely solely on such Officers’ Certificate as conclusive proof that such payments are necessary.

Wherever in this Indenture or the Securities there is mentioned, in any context (i) the payment of principal, (ii) interest, or (iii) any other amount payable on or with respect to any of the Securities or any Guarantee, such reference shall be deemed to include payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

The foregoing obligations will survive any termination, defeasance or discharge of this Indenture and any transfer by the holder or beneficial owner of a Security, and will apply mutatis mutandis to any jurisdiction in which any successor to a Payor is organized, engaged in business for tax purposes or otherwise resident for tax purposes, or any jurisdiction from or through which any payment under, or with respect to such Security (or any Guarantee) is made by or on behalf of such Payor, or any political subdivision or Governmental Authority thereof or therein having the power to tax.

53

(d) When entering into this Indenture, the parties have assumed in good faith that the interest payments under the Securities and the other Finance Documents are not and will not become subject to any deduction or withholding of Taxes on account of Swiss Withholding Tax (a “Swiss Tax Deduction”). Notwithstanding the foregoing, if a Swiss Tax Deduction should, at any time, be or become required by law and should it be unlawful for a Swiss Obligor to comply with Section 4.01(c) for any reason (where this would otherwise be required by the terms of this Indenture or any other Finance Document), then:

(i) the applicable interest rate in relation to that interest payment or guarantee payment shall be the interest rate that would have applied to that interest payment as provided for by this Indenture and the relevant Security divided by an amount equal to (x) 1 minus (y) the rate at which such Swiss Tax Deduction is required to be made under Swiss domestic tax law or applicable double taxation treaties (where the rate at which such Swiss Tax Deduction is required to be made is for this purpose expressed as a fraction); and

(ii) such Swiss Obligor shall:

(A) pay the relevant interest at the adjusted rate in accordance with the provision above; and

(B) make such Swiss Tax Deduction on the interest so recalculated; and

All references to a rate of interest under any Finance Document shall be construed accordingly and all related provisions shall apply to the deduction for Swiss Withholding Tax purposes on the recalculated interest payment.

To the extent that interest payable under the Securities or any other Finance Document becomes or may become subject to Swiss Withholding Tax the relevant Swiss Obligor shall promptly complete any procedural formalities (including submitting forms and documents required by the appropriate Tax authority) to the extent possible and necessary for such Swiss Obligor to obtain authorization (x) to make interest payments without them being subject to Swiss Withholding Tax or to being subject to Swiss Withholding Tax at a rate reduced under applicable double taxation treaties, as applicable, and (y) for a Holder of Securities, the Trustee or the Collateral Agent to obtain a full or partial refund of Swiss Withholding Tax under applicable double taxation treaties.

(e) Notwithstanding Section 4.01(d), such Swiss Obligor will not be required to make any payment of Additional Interest, if

(i) the relevant Holders are eligible for refund application or such Swiss Obligor is eligible for an exemption application;

54

(ii) the refund or the exemption to such relevant Holders or such Swiss Obligor has been confirmed in writing by the Swiss Federal Tax Administration to the satisfaction of the Trustee, acting at the direction of such Holders; and

(iii) the Trustee, acting at the direction of such Holders has given its prior written consent to such waiver of such Swiss Obligor’s obligation to pay Additional Interest which shall not be unreasonably withheld.

The relevant Holders shall provide reasonable efforts to cooperate with the applicable Swiss Obligor to secure such refund or exemption. The Trustee undertakes all reasonable efforts to obtain the documents/information required from such Holders after such Swiss Obligor was notified by the Trustee of such documents/information required. When the relevant Holders have been able to realize treaty benefits, the applicable Swiss Obligor will have a refund claim against such Holders at the amount of the treaty benefit obtained after the calculation of the payment as computed under Section 4.01(d)(i). Such refund is subject to any right of set-off pursuant to this Indenture or the other Finance Documents and subject to not being in a less favorable net after-tax position than such Holders would have been in if such Swiss Withholding Tax had not been required in the first instance.

SECTION 4.02. Reports and Other Information .

(a) Annual Financials . The Issuer shall deliver to the Trustee, as soon as available, but in any event within 120 days (or such earlier date on which the Issuer is required to file a Form 10-K under the Exchange Act, if applicable) after the end of each fiscal year of the Issuer, beginning with the fiscal year ending March 31, 2017, a consolidated balance sheet of the Issuer and its Subsidiaries as of the end of such fiscal year, and the related consolidated statements of income, cash flows and stockholders’ equity for such fiscal year, setting forth in each case in comparative form the figures for the previous fiscal year, all prepared in accordance with GAAP, with such consolidated financial statements to be audited and accompanied by (i) a report and opinion of the Issuer’s independent certified public accounting firm of recognized standing in the United States (which report and opinion shall be prepared in accordance with GAAP), stating that such financial statements fairly present, in all material respects, the consolidated financial condition, results of operations and cash flows of the Issuer as of the dates and for the periods specified in accordance with GAAP, and (ii) (if and only if the Issuer is required to comply with the internal control provisions pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 requiring an attestation report of such independent certified public accounting firm) an attestation report of such independent certified public accounting firm as to the Issuer’s internal controls pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 attesting that such internal controls meet the requirements of the Sarbanes-Oxley Act of 2002; provided, however, that the Issuer shall be deemed to have made such delivery of such consolidated financial statements and attestation report if such consolidated financial statements and attestation report shall have been made available for free within the time period specified above on the SEC’s EDGAR system (or any successor system adopted by the SEC); provided, further, however, that the Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed pursuant to EDGAR (or

Such consolidated financial statements shall be certified by a Financial Officer as, to his or her knowledge, fairly presenting, in all material respects, the consolidated financial condition, results of operations and cash flows of the Issuer and its Subsidiaries as of the dates and for the periods specified in accordance with GAAP consistently applied, and on a basis consistent with the audited consolidated financial statements referred to under Section 4.02(a), subject to normal year-end audit adjustments and the absence of footnotes.

56

(e) Rule 144A Information . So long as the Issuer is not subject to either Section 13 or 15(d) of the Exchange Act, the Issuer shall deliver to the Holders, any holder of beneficial interests in the Securities and any prospective purchaser of the Securities or a beneficial interest therein designated by a Holder or such other Person, promptly upon the request of any such Person, the 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.

(f) Communication of Information . Delivery of information under this Section 4.02 to the Trustee shall be for informational purposes only, and the Trustee’s receipt thereof shall not constitute constructive notice of any information contained therein or determinable from any information contained therein, including compliance by the Issuer or any of its Subsidiaries with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates or certificates or statements delivered to the Trustee pursuant to Section 4.02(c)).

In the case of clause (ii) above, a binding commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment, so long as the Net Proceeds are applied within 450 days after the receipt thereof. Pending the final application of any such Net Proceeds, the Issuer or such Restricted Subsidiary of the Issuer may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture, provided that the Net Proceeds of an Asset Sale of Notes Collateral shall be held in an account that is pledged as Notes Collateral.

The Issuer shall commence a Notes Collateral Asset Sale Offer with respect to Notes Collateral Excess Proceeds within 10 Business Days after the existence of Notes Collateral Excess Proceeds by providing the written notice required pursuant to Section 4.06(h), with a copy to the Trustee. To the extent that the aggregate amount of Securities (and such Pari Passu Indebtedness) tendered pursuant to a Notes Collateral Asset Sale Offer is less than the Notes Collateral Excess Proceeds, the Issuer may use any remaining Notes Collateral Excess Proceeds for any purpose that is not prohibited by this Indenture. If the aggregate principal amount of Securities (and such Pari Passu Indebtedness) surrendered by Holders thereof exceeds the amount of Notes Collateral Excess Proceeds, the Trustee shall select the Securities to be purchased in the manner described in Section 4.06(g). Upon completion of any such Notes Collateral Asset Sale Offer, the amount of Notes Collateral Excess Proceeds shall be reset at zero.

72

(d) Any Net Proceeds from any Asset Sale of Excluded Assets or ABL Collateral that secures First Priority Lien Obligations that are not applied as provided and within the time period set forth in Section 4.06(a) or 4.06(b) (it being understood that any portion of such Net Proceeds used to make an offer to purchase Securities, as described in Section 4.06(b)(i), shall be deemed to have been invested whether or not such offer is accepted) will be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $5,000,000, the Issuer shall make an offer to all Holders of Securities (and, at the option of the Issuer, to holders of any Pari Passu Indebtedness) (an “Asset Sale Offer”) to purchase the maximum principal amount of Securities (and such Pari Passu Indebtedness) that is at least $1,000 and an integral multiple of $50,000 that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal balance thereof (or, in the event such Pari Passu Indebtedness was issued with significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid interest (or, in respect of such Pari Passu Indebtedness, such lesser price, if any, as may be provided for by the terms of such Pari Passu Indebtedness), to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Section 4.06. The Issuer will commence an Asset Sale Offer with respect to Excess Proceeds within 10 Business Days after the date that Excess Proceeds exceed $5,000,000 by providing the written notice required pursuant to Section 4.06(h), with a copy to the Trustee. To the extent that the aggregate amount of Securities (and such Pari Passu Indebtedness) tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds for any purpose that is not prohibited by this Indenture. If the aggregate principal amount of Securities (and such Pari Passu Indebtedness) surrendered by Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Securities to be purchased in the manner described in Section 4.06(g). Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

(e) The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the extent such laws or regulations are applicable in connection with the repurchase of the Securities pursuant to a Notes Collateral Asset Sale Offer or an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

(f) Not later than the date upon which written notice of a Notes Collateral Asset Sale Offer or an Asset Sale Offer, as the case may be, is delivered to the Trustee as provided above, the Issuer shall deliver to the Trustee an Officers’ Certificate as to (i) the amount of the Notes Collateral Excess Proceeds or the Excess Proceeds, as the case may be, (ii) the application of the Net Proceeds from the Asset Sales pursuant to which such Notes Collateral Asset Sale Offer or Asset Sale Offer, as the case may be, is being made and (iii) the compliance of such application with the provisions of Section 4.06(b). On the specified date of purchase, the Issuer shall also irrevocably deposit with the Trustee or with a Paying Agent (or, if the Issuer or a Wholly Owned Restricted Subsidiary is acting as the Paying Agent, segregate

73

and hold in trust) an amount equal to the Notes Collateral Excess Proceeds or the Excess Proceeds, as the case may be, to be invested in Cash Equivalents, as directed in writing by the Issuer, and to be held for payment in accordance with the provisions of this Section 4.06. Upon the expiration of the period for which the Notes Collateral Asset Sale Offer or Asset Sale Offer, as the case may be, remains open (the “Offer Period”), the Issuer shall deliver to the Trustee for cancellation the Securities or portions thereof that have been properly tendered to and are to be accepted by the Issuer, along with a written payment and cancellation order. The Trustee (or the Paying Agent, if not the Trustee) shall, on the date of purchase, mail or deliver payment to each tendering Holder in the amount of the purchase price as determined by the Issuer and stated in the written payment and cancellation order. In the event that the Notes Collateral Excess Proceeds or Excess Proceeds, as the case may be, delivered by the Issuer to the Trustee are greater than the purchase price of the Securities tendered, the Trustee shall deliver the excess to the Issuer immediately after the expiration of the Offer Period for application in accordance with Section 4.06.

(g) Holders electing to have a Security purchased shall be required to surrender the Security, with an appropriate form duly completed, to the Issuer at the address specified in the notice at least three Business Days prior to the purchase date. Holders shall be entitled to withdraw their election if the Issuer receives not later than one Business Day prior to the purchase date a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security that was delivered by the Holder for purchase and a statement that such Holder is withdrawing such Holder’s election to have such Security purchased. If at the end of the Offer Period more Securities (and such Pari Passu Indebtedness, as applicable) are tendered pursuant to a Notes Collateral Asset Sale Offer or an Asset Sale Offer, as the case may be, than the Issuer is required to purchase, and if the Securities are Global Securities held by the Depository, the Depository will select the Securities to be redeemed in accordance with its operational arrangements. If the Securities are not Global Securities held by the Depository, selection of such Securities for purchase shall be made by the Trustee on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with applicable legal requirements); provided that no Securities of $1,000 or less shall be purchased in part. Selection of such Pari Passu Indebtedness, as applicable, shall be made by the representative for such Pari Passu Indebtedness pursuant to the terms of such Pari Passu Indebtedness; provided that any purchase by the Issuer of Pari Passu Indebtedness and Securities tendered pursuant to a Notes Collateral Asset Sale Offer or an Asset Sale Offer shall otherwise be made on a pro rata basis, as nearly as practicable.

(h) Written notices of a Notes Collateral Asset Sale Offer or an Asset Sale Offer shall be provided by the Issuer at least 30 but not more than 60 days before the purchase date to each Holder of Securities at such Holder’s registered address with a copy to the Trustee (or electronically pursuant to DTC’s applicable procedures). If any Security is to be purchased in part only, any notice of purchase that relates to such Security shall state the portion of the principal amount thereof that has been or is to be purchased. Holders whose Securities are purchased only in part shall be issued new Securities equal in principal amount to the unpurchased portion of the Securities surrendered. If the Securities are Global Securities held by the Depository, then the applicable operational procedures of the Depository for tendering and withdrawing securities will apply.

77

(b) Within 30 days following any Change of Control, except to the extent that the Issuer has exercised (x) its unconditional right to redeem the Securities by delivery of a notice of redemption in accordance with Article 3 or (y) its legal defeasance option or covenant defeasance option in accordance with Article 8, the Issuer shall provide a written notice (a “Change of Control Offer”) to each Holder with a copy to the Trustee stating:

(i) that a Change of Control has occurred and that such Holder has the right to require the Issuer to repurchase such Holder’s Securities at a repurchase price in cash (the “Change of Control Payment”) equal to 101% of the principal balance thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of the Holders of record on the relevant Record Date to receive interest on the related Payment Date);

(ii) the circumstances and relevant facts and financial information regarding such Change of Control;

(c) Holders electing to have a Security repurchased shall be required to surrender the Security, with an appropriate form duly completed, to the Issuer at the address specified in the notice at least three Business Days prior to the repurchase date. The Holders shall be entitled to withdraw their election if the Issuer receives not later than one Business Day prior to the repurchase date a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security that was delivered for purchase by the Holder and a statement that such Holder is withdrawing its election to have such Security repurchased. Holders whose Securities are repurchased only in part shall be issued new Securities equal in principal amount to the unpurchased portion of the Securities surrendered. If the Securities are Global Securities held by the Depository, then the applicable operational procedures of the Depository for tendering and withdrawing securities will apply.

(d) On the repurchase date, all Securities repurchased by the Issuer under this Section 4.08 shall be delivered to the Trustee for cancellation, and the Issuer shall pay the purchase price plus accrued and unpaid interest to the Holders entitled thereto.

(e) A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

(f) Notwithstanding the foregoing provisions of this Section 4.08, the Issuer shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.08 applicable to a Change of Control Offer made by the Issuer and purchases all Securities validly tendered and not withdrawn under such Change of Control Offer.

(g) Securities repurchased by the Issuer pursuant to a Change of Control Offer will have the status of Securities issued but not outstanding or will be retired and canceled at the option of the Issuer. Securities purchased by a third party pursuant to Section 4.08(f) will have the status of Securities issued and outstanding.

78

(h) At the time the Issuer delivers Securities to the Trustee that are to be accepted for repurchase, the Issuer shall also deliver an Officers’ Certificate stating that such Securities are to be accepted by the Issuer pursuant to and in accordance with the terms of this Section 4.08 and confirming whether the Securities will be considered issued but not outstanding, or include orders to cancel the repurchased Securities. A Security shall be deemed to have been accepted for repurchase at the time the Trustee, directly or through an agent, provides payment therefor to the surrendering Holder.

(i) Prior to providing written notice to the Holders of any Change of Control Offer, the Issuer shall deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent contained herein to the right of the Issuer to make such offer have been complied with.

(j) The Issuer 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 4.08. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 4.08, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.08 by virtue thereof.

(k) If holders of not less than 90% in aggregate principal amount of the outstanding Securities validly tender and do not withdraw such Securities in a Change of Control Offer and the Issuer, or any third party making a Change of Control offer in lieu of the Issuer as described above, purchases all of the Securities validly tendered and not withdrawn by such holders, the Issuer or such third party will have the right, upon not less than 15 days nor more than 60 days’ prior notice, provided that such notice is given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Securities that remain outstanding following such purchase on a date at a price in cash equal to the Change of Control Payment.

SECTION 4.09. Further Instruments and Acts . The Issuer shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

SECTION 4.10. Future Guarantors . The Issuer shall cause each Restricted Subsidiary, within 10 Business Days of becoming a Restricted Subsidiary, to execute and deliver to the Trustee a supplemental indenture substantially in the form of Exhibit C pursuant to which such Restricted Subsidiary shall guarantee the Issuer’s Obligations under the Securities and this Indenture.

SECTION 4.11. Liens . The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer to exist (a) any Lien (except Permitted Liens) on any asset or property of the Issuer or such Restricted Subsidiary securing Indebtedness or (b) any Lien on ABL Collateral securing any First Priority Lien Obligation of the Issuer or any Guarantor without effectively providing that the Securities or the applicable Guarantee, as the case may be, shall be secured by a junior security interest (subject to Permitted Liens) upon the assets or property constituting such ABL Collateral for such First

79

Priority Lien Obligations; provided, however , that (1) all such Liens on the ABL Collateral shall be subject to the Intercreditor Agreement and (2) no such junior security interest upon any Lockbox Account constituting ABL Collateral shall be required.

For purposes of determining compliance with this Section 4.11, in the event that a Lien securing an item of Indebtedness (or any portion thereof) meets the criteria of more than one of the categories of Liens described in the foregoing paragraph or in clauses (1) through (29) of the definition of “Permitted Liens,” then the Issuer shall, in its sole discretion, classify or reclassify, or later divide, classify or reclassify, such Lien securing an item of Indebtedness (or any portion thereof) in any manner that complies with this Section 4.11.

With respect to any Lien securing Indebtedness that was permitted to secure such Indebtedness at the time of the Incurrence of such Indebtedness, such Lien shall also be permitted to secure any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any increase in the amount of such Indebtedness in connection with any accrual of interest, the accretion of accreted value, the payment of interest or dividends in the form of additional Indebtedness, amortization of original issue discount and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies, in each case in respect of such Indebtedness.

The Liens granted in favor of the Collateral Agent on the Notes Collateral to secure the Obligations in respect of the Securities shall be subordinated to any Lien granted in favor of any third party on such Notes Collateral that is permitted by clause (17) of the definition of “Permitted Liens” (other than such Permitted Liens in favor of the Issuer or any Restricted Subsidiary) and, upon request from the Issuer (which shall be accompanied by an Officers’ Certificate), the Collateral Agent shall take such action as is requested by the Issuer to reflect such subordination (including the entry into non-disturbance and similar agreements) in connection with the licensing of Intellectual Property and any other transactions permitted by such clause (17), such as confirming in writing to any actual or potential licensee or counterparty that (i) the Collateral Agent shall not, by enforcing its Lien, or otherwise, disturb or otherwise affect the prior Lien of such licensee or counterparty or any other rights of the licensee or counterparty under the relevant agreements, (ii) so long as such licensee or counterparty is not in breach of or default under its agreements with the Issuer or its Subsidiaries, neither the Collateral Agent nor any successor thereto shall assert any rights of the Issuer or any Subsidiary to terminate any rights or benefits of the licensee or counterparty pursuant to the terms of such agreements, and (iii) upon entry by the Issuer or any Subsidiary into any non-exclusive license agreement with respect to such Intellectual Property with the party licensing such Intellectual Property, such non-exclusive licensee shall take its license rights under such license agreement free of the Liens on the Notes Collateral.

SECTION 4.12. Maintenance of Office or Agency .

(a) The Issuer shall maintain an office or agency (which may be an office of the Trustee or an Affiliate of the Trustee or Registrar) where Securities may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer in respect of the Securities and this Indenture may be made. The Issuer shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If

80

at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made at the corporate trust place of payment and notices and demands may be made at the Corporate Trust Office of the Trustee as set forth in Section 12.01.

(b) The Issuer may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however , that no such designation or rescission shall in any manner relieve the Issuer of its obligation to maintain an office or agency for such purposes. The Issuer shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

(c) The Issuer hereby designates the Corporate Trust Office of the Trustee or its agent as such office or agency of the Issuer in accordance with Section 2.04.

SECTION 4.13. After-Acquired Property . Upon the acquisition by any Issuer or any Guarantor of any assets or property, including any new Subsidiary of the Issuer or any Guarantor (in each case, other than Excluded Assets) (“After-Acquired Property”), the Issuer or such Guarantor shall promptly execute and deliver such mortgages, deeds of trust, security instruments, pledge agreements, financing statements and certificates and opinions of counsel as shall be reasonably necessary to vest in the Collateral Agent a perfected security interest or other Lien, subject only to Permitted Liens, in such After-Acquired Property and to have such After-Acquired Property (but subject to certain limitations, if applicable, including as described under Article 11) added to the Notes Collateral, and shall promptly deliver such Officers’ Certificates and Opinions of Counsel as are customary in secured financing transactions in the relevant jurisdictions or as are reasonably requested by the Trustee or the Collateral Agent (subject to customary assumptions, exceptions and qualifications), and thereupon all provisions of this Indenture relating to the Notes Collateral shall be deemed to relate to such After-Acquired Property to the same extent and with the same force and effect; provided that if granting a security interest or Lien in such After-Acquired Property requires the consent of a third party, the Issuer shall use commercially reasonable efforts to obtain such consent with respect to the security interest or Lien for the benefit of the Collateral Agent on behalf of the Holders of the Securities; provided, further , that if such third party does not consent to the granting of such security interest or Lien after the use of such commercially reasonable efforts, the Issuer or such Guarantor, as the case may be, will not be required to provide such security interest or Lien (so long as no other Person is granted a Lien (other than a Permitted Lien that is not an Excluded Permitted Lien) on such After-Acquired Property securing any Indebtedness following such acquisition or in contemplation thereof); and provided , further , that with respect to the security interest in After-Acquired Property that constitutes ABL Collateral securing First Priority Lien Obligations, such security interest securing the Securities and the Guarantees shall be subject to the Intercreditor Agreement. Notwithstanding the foregoing, if any property or assets of the Issuer or any Guarantor originally deemed to be an Excluded Asset at any point ceases to be an Excluded Asset pursuant to such defined term, all or the applicable portion of such property and assets shall be deemed to be After-Acquired Property and shall be added to the Notes Collateral in accordance with the previous sentence.

81

SECTION 4.14. Intellectual Property . The Issuer shall, at its sole expense, either directly or by using commercially reasonable efforts to cause any Restricted Subsidiary or any licensee to do so, take any and all commercially reasonable actions to (a) diligently maintain the Intellectual Property owned or held by the Issuer or any Restricted Subsidiary on the Issue Date and (b) to the extent the Issuer, any Restricted Subsidiary or any licensee in good faith determines appropriate, diligently defend or assert the Intellectual Property against infringement or interference by any other Persons and against any claims of invalidity or unenforceability by any other Persons (including by bringing any legal action for infringement or defending any counterclaim of invalidity or action for declaratory judgment of non-infringement) in each case where the failure to so act, prepare, execute, deliver or file would reasonably be expected to have a material adverse effect on the Intellectual Property related to Blood Grouping or Serological Disease Screening, or the business, results of operations or financial condition, of the Issuer and its Restricted Subsidiaries, in each case, taken as a whole. The Issuer shall not, and shall use its commercially reasonable efforts to cause any Restricted Subsidiary or any licensee not to, disclaim or abandon, or fail to take any action the Issuer in good faith determines appropriate to prevent the disclaimer or abandonment of, the Intellectual Property, in each case where such disclaimer, abandonment or failure to take any such action would reasonably be expected to have a material adverse effect on the Intellectual Property related to Blood Grouping or Serological Disease Screening, or the business, results of operations or financial condition, of the Issuer and its Restricted Subsidiaries, in each case, taken as a whole. Any license of the Intellectual Property rights related to MosaiQ™ (to the extent that such Intellectual Property right is directly owned, licensed or otherwise held by the Issuer or any Guarantor on the Issue Date and included in the Notes Collateral on the date of such license) to the Issuer or any of its Subsidiaries shall only be to the Issuer or a Guarantor.

SECTION 4.15. Line of Business . Except to such extent as would not be material to the Issuer and its Restricted Subsidiaries as a whole, the Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, engage in any line of business other than those businesses engaged in on the Issue Date and businesses or other activities that are reasonably similar, ancillary, complementary or related to, or a reasonable extension, development or expansion of, those businesses engaged on the Issue Date.

SECTION 4.16. Use of Proceeds . The Issuer shall use, or will cause its Restricted Subsidiaries to use, the net proceeds from the issuance and sale of the Securities to repay all outstanding obligations under the Issuer’s Amended and Restated Credit, Security and Guaranty Agreement, dated as of August 3, 2015, with Midcap Financial Trust, as amended, to finance the construction or acquisition of the approximately 92,000 square foot manufacturing, laboratory and office facility in the process of being constructed at the Midlothian Biocampus near Edinburgh, Scotland, to finance the construction or acquisition of a manufacturing facility for MosaiQ™ consumables located in Eysins, Switzerland, to fund the Cash Reserve Account on the Issue Date in the amount of the Initial Cash Reserve Amount, to fund the Cash Reserve Account on the date of issuance of the Additional Securities in the amount of the Additional Cash Reserve Amount, to pay fees, costs and expenses arising in connection with the issuance of the Securities and for general corporate purposes.

SECTION 4.17. Existence . Subject to Article 5, each of the Issuer and each Guarantor will do or cause to be done all things necessary to preserve and keep in full force and

82

effect its respective existences, rights (charter and statutory), licenses and franchises; provided, however, that the Issuer shall not be required to preserve any such right, license or franchise, or the existence of any Guarantor, if the Issuer shall determine in good faith that the preservation thereof is no longer desirable in the conduct of the business of the Issuer and its Restricted Subsidiaries, taken as a whole.

SECTION 4.18. Scotland Sale/Leaseback Transaction . If the Issuer or any Guarantor consummates a Sale/Leaseback Transaction in respect of the approximately 92,000 square foot manufacturing, laboratory and office facility in the process of being constructed at the Midlothian Biocampus near Edinburgh, Scotland, the Issuer or such Guarantor shall cause the related lease agreement to permit the granting of a Lien in respect of the Issuer’s or such Guarantor’s rights thereunder for the benefit of the Collateral Agent.

SECTION 4.19. Cash Reserve Account . On the Issue Date, the Issuer shall deposit, or cause to be deposited, funds equal to the Initial Cash Reserve Amount into the Cash Reserve Account and, on the date of issuance of the Additional Securities, the Issuer shall deposit, or cause to be deposited, funds equal to the Additional Cash Reserve Amount into the Cash Reserve Account. For so long as the Securities are outstanding, the Trustee shall maintain the Cash Reserve Account. The Trustee shall not withdraw funds from or invest funds in the Cash Reserve Account and shall not permit any other Person to withdraw funds from or invest funds in the Cash Reserve Account, except (a) absent the occurrence and continuance of an Event of Default, the funds in the Cash Reserve Account may be invested in Cash Equivalents at the written direction of the Issuer, (b) after the occurrence and during the continuance of any Event of Default, acting at the direction of the Holders of a majority of the aggregate principal amount of the Securities then outstanding, the Trustee shall apply the Cash Equivalents in the Cash Reserve Account to the Obligations or (c) upon written request of the Issuer to the Trustee, as evidenced by an Officers’ Certificate (including the calculation of the then-applicable Cash Reserve Amount), the Trustee shall remit Cash Equivalents in the Cash Reserve Account to, or at the written direction of, the Issuer in an amount not greater than the excess (if any) above the then-applicable Cash Reserve Amount. Upon the release of the Notes Collateral from the Lien and security interest created by the Security Documents pursuant to Section 11.02(a)(v) or Section 11.08, the Trustee shall remit Cash Equivalents in the Cash Reserve Account to, or at the written direction of, the Issuer. The Trustee will not be responsible for the costs of any such investments, and shall have no liability for any investment losses, including any market loss on any investment liquidated prior to maturity in order to make a payment required hereunder. All of such costs shall be charged against the funds on deposit in the Cash Reserve Account. With respect to any direction or notice in respect of the investment of any funds in the Cash Reserve Account received by the Trustee after 10:00 A.M., New York City time, the Trustee shall not be required to effect such investment instruction until the following Business Day. All amounts earned on the investments of funds in the Cash Reserve Account will be treated as income of the Issuer for United States federal income tax purposes. The Issuer acknowledges that, to the extent regulations of the Comptroller of the Currency, or other applicable regulatory entity, grant the Issuer the right to receive individual confirmations of security transactions at no additional cost, as they occur, the Issuer specifically waives receipt of such confirmations to the extent permitted by law. The Trustee will furnish the Issuer with periodic cash transaction statements that include detail for all investment transactions made by the Trustee hereunder.

87

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

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

A Default under clause (c) or (l) above shall not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities notify the Issuer (and also the Trustee if given by the Holders) of the Default and the Issuer does not cure such Default within the time specified in clause (c) or (l) above 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.” The Issuer shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any event that is, or with the giving of notice or the lapse of time or both would become, an Event of Default, its status and what action the Issuer is taking or proposes to take in respect thereof.

SECTION 6.02. Acceleration . If an Event of Default (other than an Event of Default specified in Section 6.01(e) or 6.01(f) with respect to the Issuer) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding Securities by written notice to the Issuer may, and if such notice is given by the Holders such notice shall be given to the Issuer and the Trustee, declare that the principal of, and the premium,

88

if any, and accrued but unpaid interest on, all the Securities is 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(e) or 6.01(f) with respect to the Issuer occurs, the principal of, and the premium, if any, and accrued but unpaid interest on, all the Securities shall ipso facto become and be immediately due and payable, without any declaration or other act on the part of the Trustee or any Holders. The Holders of a majority in principal amount of the Securities by notice to the Trustee may rescind an acceleration and its consequences if all existing Events of Default (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived.

If the principal of, premium, if any or accrued and unpaid interest, if any, on the Securities becomes due and payable as provided above (an “Acceleration”) prior to the First Call Date, the principal of, and the premium, if any, and accrued but unpaid interest on the Securities that shall be due and payable in connection with any payment that occurs following such Acceleration and prior to the First Call Date shall equal the redemption price set forth in Paragraph 5 of the form of Security set forth in Exhibit A hereto in effect on the date such amount is paid, as if such Acceleration were an optional redemption of the Securities affected thereby on the date such amount is paid. The amount described in the preceding sentence is intended to be liquidated damages and not unmatured interest or a penalty.

In the event of any Event of Default specified in Section 6.01(d), such Event of Default and all consequences thereof (excluding, however, any resulting payment default) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders of the Securities, if within 20 days after such Event of Default arose the Issuer delivers an Officers’ Certificate to the Trustee stating that (x) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged, (y) the Holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (z) the default that is the basis for such Event of Default has been cured, it being understood that in no event shall an acceleration of the principal amount of the Securities as described above be annulled, waived or rescinded upon the happening of any such events.

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

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. To the extent required by law, all available remedies are cumulative.

SECTION 6.04. Waiver of Past Defaults . Provided the Securities are not then due and payable by reason of a declaration of acceleration, the Holders of a majority in principal amount of the then outstanding Securities by written notice to the Trustee may waive an existing

89

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 the terms of this Indenture or (c) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected. When a Default is waived, it is deemed cured and the Issuer, the Trustee and the Holders will be restored to their former positions and rights under this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. Any past Default or compliance with any provisions may be waived with the consent of the Holders of a majority in principal amount of the Securities then outstanding.

SECTION 6.05. Control by Majority . The Holders of a majority in principal amount of the then outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. Prior to taking any action under this Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

SECTION 6.06. Limitation on Suits .

(a) 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:

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

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

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

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

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

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

SECTION 6.07. Rights of the 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

90

or provided for in this Indenture or in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

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

SECTION 6.09. Trustee May File Proofs of Claim . The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation, expenses disbursements and advances of the Trustee (including counsel, accountants, experts or such other professionals as the Trustee deems necessary, advisable or appropriate)) and the Holders allowed in any judicial proceedings relative to the Issuer or any Guarantor, their creditors or their property, shall be entitled to participate as a member, voting or otherwise, of any official committee of creditors appointed in such matters and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions and be a member of a creditors’ or other similar committee, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.06.

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

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

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

THIRD: to the Issuer or, to the extent the Trustee collects any amount for any Guarantor, to such Guarantor.

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.10. At least 15 days before such record date, the Trustee shall provide to each Holder and the Issuer a written 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

91

omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in principal amount of the Securities.

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

SECTION 6.13. Holder Request . At the written request of the Issuer or any Holder (or any holder of beneficial interests in the Securities that certifies to the Trustee that it is a holder of such beneficial interests or is actually known by the Trustee to be such a holder of beneficial interests as evidenced by a Confidentiality Agreement that has previously been delivered to the Trustee), the Trustee shall, as soon as practicable after receipt of such request and at the Issuer’s sole cost and expense, (a) contact each Holder or each other Holder (and each other holder of beneficial interests in the Securities) to request each such other Holder or other Holder (and each such other holder of beneficial interests in the Securities) to provide its written permission to being identified to the Issuer or the requesting Holder (or holder of beneficial interests in the Securities) by the Trustee, to the extent the Trustee has actual knowledge of the identity of such Holder or other Holder (or other holder of beneficial interests in the Securities), including pursuant to Section 4.02(f) and (b) disclose to the Issuer or the requesting Holder (or other holder of beneficial interests in the Securities) the identity of any such Holder or other Holder (and any such other holder of beneficial interests in the Securities) who provides such written permission to the Trustee.

SECTION 7.03. Individual Rights of Trustee .

Any Paying Agent or Registrar may do the same with like rights. However, the Trustee must comply with Sections 7.09 and 7.10.

The Trustee shall not be charged with knowledge of any Default or Event of Default under Section 6.01(c), 6.01(d), 6.01(e), 6.01(f), 6.01(g), 6.01(h), 6.01(i), 6.01(j), 6.01(k) or 6.01(l) unless either (a) a Trust Officer shall have actual knowledge thereof or (b) the Trustee shall have received written notice thereof in accordance with Section 12.01 from the Issuer, any Guarantor or any Holder.

SECTION 7.05. Notice of Defaults . If a Default occurs and is continuing and if it is actually known to the Trustee, the Trustee shall provide to each Holder written notice of the

SECTION 7.06. Compensation and Indemnity . The Issuer shall pay to the Trustee from time to time reasonable compensation for its services, as agreed between the Issuer and the Trustee. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee upon request for all reasonable and documented 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 Issuer and each Guarantor, jointly and severally, shall indemnify the Trustee against any and all loss, liability, claim, damage or expense (including reasonable and documented attorneys’ fees and expenses) incurred by or in connection with the acceptance or administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture or a Guarantee against the Issuer or a Guarantor (including this Section 7.06) and defending itself against or investigating any claim (whether asserted by the Issuer, any Guarantor, any Holder or any other Person). The obligation to pay such amounts shall survive the discharge of this Indenture, the payment in full or defeasance of the Securities or the removal or resignation of the Trustee. The Trustee shall notify the Issuer of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided , however , that any failure so to notify the Issuer shall not relieve the Issuer or any Guarantor of its indemnity obligations hereunder. The Issuer shall defend the claim and the indemnified party shall provide reasonable cooperation at the Issuer’s expense in the defense. Such indemnified parties may have separate counsel and the Issuer and the Guarantors, as applicable, shall pay the reasonable and documented fees and expenses of such counsel; provided , however , that the Issuer shall not be required to pay such fees and expenses if it assumes such indemnified parties’ defense and, in such indemnified parties’ reasonable judgment, there is no conflict of interest between the Issuer and the Guarantors, as applicable, and such parties in connection with such defense. The Issuer need not reimburse any expense or indemnify against any loss, liability or expense incurred by an indemnified party through such party’s own willful misconduct or gross negligence (as determined by a final, non-appealable order of a court of competent jurisdiction) or with respect to any settlement made without its consent.

To secure the Issuer’s and the Guarantors’ payment obligations in this Section 7.06, 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 premium, if any, and interest on, particular Securities.

The Issuer’s and the Guarantors’ payment obligations pursuant to this Section 7.06 shall survive the satisfaction or discharge of this Indenture, any rejection or termination of this Indenture under any bankruptcy law or the resignation or removal of the Trustee. Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee

96

incurs expenses after the occurrence of a Default specified in Section 6.01(e) or Section 6.01(f) with respect to the Issuer, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if repayment of such funds or adequate indemnity against such risk or liability is not assured to its satisfaction.

SECTION 7.07. Replacement of Trustee .

(a) The Trustee may resign in writing at any time upon 30 days prior notice to the Issuer by so notifying the Issuer.

The Trustee, in its individual capacity and as Trustee, agrees and acknowledges that all confidential information (“Confidential Information”) provided to the Trustee by the Issuer or any Subsidiary (or any direct or indirect equityholder of the Issuer or such Subsidiary) or any Holder (or holder of a beneficial interest in the Securities) may be considered to be proprietary and confidential information. The Trustee agrees to take reasonable precautions to keep Confidential Information confidential, which precautions shall be no less stringent than those that the Trustee employs to protect its own confidential information.

98

than as set forth herein, and shall not use for any purpose other than the exercise of the Trustee’s rights and the performance of its obligations under this Indenture, any Confidential Information without the prior written consent of the Issuer or such Holder (or such holder of a beneficial interest in the Securities), as applicable. The Trustee shall limit access to Confidential Information received hereunder to (a) its directors, officers, managers and employees and (b) its legal advisors, to each of whom disclosure of Confidential Information is necessary for the purposes described above; provided, however, that in each case such party has expressly agreed to maintain such information in confidence under terms and conditions substantially identical to the terms of this Section 7.11.

The Trustee further agrees that it shall not acquire any rights against the Issuer or any of its Subsidiaries or any employee, officer, director, manager, representative or agent of the Issuer or any of its Subsidiaries or any Holder (or any holder of a beneficial interest in the Securities), as applicable (together with the Issuer, “Confidential Parties”) as a result of the disclosure of Confidential Information to the Trustee and that no Confidential Party has any duty, responsibility, liability or obligation to any Person as a result of any such disclosure.

In the event the Trustee is required to disclose any Confidential Information received hereunder in order to comply with any laws, regulations or court orders, it may disclose such information only to the extent necessary for such compliance; provided, however, that it shall give the Issuer or any Holder (or any holder of a beneficial interest in the Securities), as applicable, reasonable advance written notice of any court proceeding in which such disclosure may be required pursuant to a court order so as to afford the Issuer or any Holder (or any holder of a beneficial interest in the Securities), as applicable, full and fair opportunity to oppose the issuance of such order and to appeal therefrom and shall cooperate reasonably with the Issuer or any Holder (or any holder of a beneficial interest in the Securities), as applicable, in opposing such court order and in securing confidential treatment of any such information to be disclosed or obtaining a protective order narrowing the scope of such disclosure.

Each of the Paying Agent and the Registrar agrees to be bound by this Section 7.11 to the same extent as the Trustee.

ARTICLE 8

DISCHARGE OF INDENTURE; DEFEASANCE

SECTION 8.01. Discharge of Liability on Securities; Defeasance . This Indenture shall be discharged and shall cease to be of further effect (except as to surviving rights of registration of transfer or exchange of Securities, as expressly provided for in this Indenture) as to all outstanding Securities when:

(a) either (i) all the Securities theretofore authenticated and delivered (other than Securities pursuant to Section 2.08 that have been replaced or paid and Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid by the Issuer or discharged from such trust) have been delivered to the Trustee for cancellation or (ii) all of the Securities that have not been delivered to the Trustee for cancellation (a) have become due and payable, (b) will become due and payable at their Stated Maturity within one year or (c) if redeemable at the option of the Issuer, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer, and the Issuer has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the Securities not theretofore delivered to the Trustee for cancellation, for principal of, and premium, if any, and interest on, the Securities to the date of deposit, together with irrevocable instructions from the Issuer directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be;

(b) the Issuer or the Guarantors have paid all other sums payable under this Indenture; and

(c) the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with.

(d) Notwithstanding clauses (a) and (b) above, the Issuer’s obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 6.07, 7.06 and 7.07 and in this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Issuer’s obligations in Sections 7.06, 8.05 and 8.06 shall survive such satisfaction and discharge.

(e) Subject to Section 8.01(d) and Section 8.02, the Issuer at any time may terminate (i) all its obligations under the Securities and this Indenture (with respect to such Securities) (“legal defeasance option”) or (ii) its obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.10, 4.11, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20 and the operation of Section 4.08, Section 5.01 and Sections 6.01(c), 6.01(d), 6.01(e) (with respect to Restricted Subsidiaries of the Issuer only), 6.01(f) (with respect to Restricted Subsidiaries of the Issuer only), 6.01(g), 6.01(h), 6.01(i), 6.01(j), 6.01(k) and 6.01(l) (“covenant defeasance option”).

In the event that the Issuer terminates all of its obligations under the Securities and this Indenture (with respect to such Securities) by exercising its legal defeasance option or its covenant defeasance option, the obligations of each Guarantor under its Guarantee of such Securities and the Security Documents shall be terminated simultaneously with the termination of such obligations.

If the Issuer exercises its legal defeasance option, payment of the Securities so defeased may not be accelerated because of an Event of Default. If the Issuer exercises its

100

covenant defeasance option, payment of the Securities so defeased may not be accelerated because of an Event of Default specified in Section 6.01(c), 6.01(d), 6.01(e) (to the extent such Section 6.01(e) applies to Restricted Subsidiaries), 6.01(f) (to the extent such Section 6.01(f) applies to Restricted Subsidiaries), 6.01(g), 6.01(h), 6.01(i), 6.01(j), 6.01(k) or 6.01(l) or because of the failure of the Issuer to comply with Sections 4.13 and 5.01.

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

SECTION 8.02. Conditions to Defeasance .

(a) The Issuer may exercise its legal defeasance option or its covenant defeasance option only if:

(v) in the case of the legal defeasance option, the Issuer shall have delivered to the Trustee an opinion of a tax counsel of nationally recognized standing in the United States stating that (1) the Issuer has received from, or there has been published by, the IRS a ruling, or (2) since the date of this Indenture there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such opinion of a tax counsel of nationally recognized standing in the United States shall confirm that, the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit and defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred;

101

(vi) in the case of the covenant defeasance option, the Issuer shall have delivered to the Trustee an opinion of a tax counsel of nationally recognized standing in the United States to the effect that the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit and defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred; and

Subject to any applicable abandoned property law, the Trustee and each Paying Agent shall pay to the Issuer upon written 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 Issuer for payment as general creditors, and the Trustee and each Paying Agent shall have no further liability with respect to such monies.

102

enjoining, restraining or otherwise prohibiting such application, the Issuer’s obligations under this Indenture and the Securities so discharged or defeased shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or any 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 Issuer has made any payment of principal of or interest on any such Securities because of the reinstatement of its obligations, the Issuer 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 any Paying Agent.

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

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

105

SECTION 9.03. Revocation and Effect of Consents and Waivers .

(a) A consent to an amendment, supplement or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent, supplement or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent, supplement or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date on which the Trustee receives an Officers’ Certificate from the Issuer certifying that the requisite principal amount of Securities have consented. After an amendment, supplement or waiver becomes effective, it shall bind every Holder. An amendment, supplement or waiver becomes effective upon the (i) receipt by the Issuer or the Trustee of consents by the Holders of the requisite principal amount of Securities, (ii) satisfaction of conditions to effectiveness as set forth in this Indenture and any indenture supplemental hereto containing such amendment, supplement or waiver, (iii) execution of such amendment or waiver (or supplemental indenture) by the Issuer and the Trustee and (iv) delivery to the Trustee of the Officers’ Certificate and Opinion of Counsel required under Article 12.

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

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

SECTION 9.05. Trustee to Sign Amendments . The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment, the Trustee shall be entitled to receive indemnity satisfactory to it and shall be provided with, and (subject to Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment, supplement or waiver is authorized or permitted by this Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Issuer and the Guarantors, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 9.03).

106

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

SECTION 9.07. Additional Voting Terms; Calculation of Principal Amount . All Securities issued under this Indenture shall vote and consent together on all matters (as to which any of such Securities may vote) as one class. Determinations as to whether Holders of the requisite aggregate principal amount of Securities have concurred in any direction, waiver or consent shall be made in accordance with this Article 9 and Section 2.14.

ARTICLE 10

GUARANTEES

SECTION 10.01. Guarantees .

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

(b) Each Guarantor further agrees that (to the extent permitted by law) the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from each such Guarantor, and that each such Guarantor shall remain bound under this Article 10 notwithstanding any extension or renewal of any Guaranteed Obligation. The Guaranteed Obligations of a Guarantor will be secured by security interests (subject to Permitted Liens) in the Notes Collateral owned by such Guarantor to the extent provided for in the Security Documents and as required pursuant to Sections 4.11 and 4.13.

(c) Each Guarantor waives presentation to, demand of payment from and protest to the Issuer of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Guarantor hereunder shall not be affected by (i) the failure of any Holder, the Trustee or the Collateral Agent to assert any claim or demand or to enforce any right or remedy against the Issuer or any other Person under this Indenture, the Securities, any Security Document, or any other agreement or otherwise; (ii) any extension or renewal of this Indenture, the Securities, any Security Document or any other agreement;

107

(iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities, any Security Document or any other agreement; (iv) the release of any security held by any Holder, the Trustee or the Collateral Agent for the Guaranteed Obligations or any Guarantor; (v) the failure of any Holder, the Trustee or the Collateral Agent to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (vi) any change in the ownership of such Guarantor, except as provided in Section 10.02(c).

(d) Each Guarantor hereby waives any right to which it may be entitled to have its obligations hereunder divided among the Guarantors, such that such Guarantor’s obligations would be less than the full amount claimed. Each Guarantor hereby waives any right to which it may be entitled to have the assets of the Issuer or any other Guarantor first be used and depleted as payment of the Issuer’s or such Guarantor’s obligations hereunder prior to any amounts being claimed from or paid by such Guarantor hereunder. Each Guarantor hereby waives any right to which it may be entitled to require that the Issuer be sued prior to an action being initiated against such Guarantor. For the avoidance of doubt, each Guarantor irrevocably and unconditionally waives any right it may have under Jersey law by virtue of the droit de discussion or droit de division .

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

(f) Except as expressly set forth in Sections 8.01 and 10.02, the obligations of each 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 Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder, the Trustee or the Collateral Agent to assert any claim or demand or to enforce any remedy under this Indenture, the Securities, any Security Document or any other agreement, 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 that may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of any Guarantor as a matter of law or equity.

(g) Except as expressly set forth in Sections 8.01 and 10.02, each Guarantor agrees that its Guarantee shall remain in full force and effect until payment in full of its Guaranteed Obligations. Except as expressly set forth in Sections 8.01 and 10.02, each Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Issuer or otherwise.

108

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

(i) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each Guarantor further agrees that, as between it, on the one hand, and the Holders, the Trustee and the Collateral Agent, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of any 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 Guarantor for the purposes of this Section 10.01.

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

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

SECTION 10.02. Limitation on Liability .

(a) Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under this Indenture, can be guaranteed hereby without rendering the Guarantee, as it relates to such Guarantor, void or voidable under applicable laws relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally or, in the case of Quotient Suisse or any other Swiss Obligor, applicable Swiss corporate law.

109

(b) If and to the extent that a Swiss Obligor is liable under this Indenture or the Securities for obligations of any other obligor (other than the wholly owned direct or indirect subsidiaries of such Swiss Obligor) and if complying with such obligation would constitute a repayment of capital ( Einlagerückgewähr ), a violation of the legally protected reserves ( gesetzlich geschützte Reserven ) or the payment of a constructive dividend ( verdeckte Gewinnausschüttung ) by such Swiss Obligor or would otherwise be restricted under Swiss mandatory law and accounting principles then applicable (the “Restricted Obligations”), such Swiss Obligor’s liability will be limited to the amount of such Swiss Obligor’s freely disposable equity in accordance with Swiss law and Swiss accounting principles (the “Swiss Available Amount”).

The limitation in this Section 10.02(b) shall only apply to the extent that it constitutes a requirement under Swiss mandatory legal and accounting principles at the time a Swiss Obligor is required to perform the Restricted Obligations. Such limitation will not free such Swiss Obligor from its obligations in excess of the Swiss Available Amount, but will merely postpone the performance date thereof until such time(s) when such performance is again permitted from a Swiss legal and Swiss accounting point of view.

If the enforcement of the obligations of a Swiss Obligor would be limited due to the effects referred to in this Indenture, such Swiss Obligor shall further, to the extent permitted by applicable law and accounting principles and upon request by the Trustee, promptly (i) transfer statutory reserves into unrestricted, distributable reserves, (ii) write up or realize any of its assets that are shown in its balance sheet with a book value that is significantly lower than the market value of the assets, in case of realization, however, only if such assets are not necessary for such Swiss Obligor’s business ( nicht betriebsnotwendig ) and such sale is permitted under this Indenture and the Security Documents and (iii) take all other measures necessary or useful to allow the Trustee to obtain the maximum benefit under this guarantee.

Such Swiss Obligor shall, and any holding company of such Swiss Obligor that is a party to this Indenture shall procure that such Swiss Obligor shall, take and cause to be taken all and any action as soon as reasonably practicable but in any event within 40 days from the request of the Trustee, including (i) the passing of any shareholders’ resolutions to approve any payment or other performance under this Indenture or any of the Security Documents, (ii) the provision of an up-to-date audited interim balance sheet, (iii) the provision of a determination by such Swiss Obligor of the Swiss Available Amount based on such audited interim balance sheet, (iv) the provision of a confirmation from the auditors of such Swiss Obligor that the payment in an amount corresponding to the Swiss Available Amount or the performance of other obligations is in compliance with the provisions of Swiss corporate law that are aimed at protecting the share capital and legal reserves and (v) the obtaining of any other confirmations which may be necessary or useful as a matter of Swiss mandatory law in force at the time of enforcement, in order to allow a prompt payment or performance of other obligations with a minimum of limitations.

If Swiss Withholding Tax is required to be deducted from any payment under this Indenture or the Security Documents, including but not limited to, any guarantee payment and any payment of proceeds of any enforcement under applicable law at the time of enforcement, the relevant Swiss Obligor:

(i) shall use its best efforts to ensure that the proceeds of any enforcement can be paid without deduction of Swiss Withholding Tax, or with deduction of Swiss Withholding Tax at a reduced rate, by discharging the liability to such tax by notification pursuant to applicable law (including tax treaties) rather than payment of the tax (the “Swiss Notification Procedure”);

110

(ii) shall deduct the Swiss Withholding Tax at such rate (being 35% on the date hereof) as in force from time to time if the Swiss Notification Procedure does not apply; or shall deduct the Swiss Withholding Tax at the reduced rate resulting after discharge of part of such tax by notification if the Swiss Notification Procedure applies for a part of the Swiss Withholding Tax only; and shall pay within the time allowed any such taxes deducted to the Swiss Federal Tax Administration; and

(iii) shall promptly notify the respective beneficiary or beneficiaries that such notification or, as the case may be, deduction has been made, and provide the respective beneficiary or beneficiaries with evidence that such a notification of the Swiss Federal Tax Administration has been made or, as the case may be, such taxes deducted have been paid to the Swiss Federal Tax Administration.

In the case of a deduction of Swiss Withholding Tax, the Swiss Obligor shall use its best efforts to ensure that any person that is entitled to a full or partial refund of the Swiss Withholding Tax deducted from such payment under this Indenture or the Securities, will, as soon as possible after such deduction: request a refund of the Swiss Withholding Tax under applicable law (including tax treaties), and pay to the respective beneficiary or beneficiaries upon receipt any amount so refunded.

The respective beneficiary or beneficiaries shall co-operate with the Swiss Obligor to secure such refund. To the extent such a deduction is made, any Swiss Obligor shall not be obliged to pay any Additional Amounts pursuant to Section 4.01(c) or otherwise hold harmless the beneficiary or the beneficiaries in relation to any such deduction.

To the extent such Swiss Obligor is required to deduct Swiss Withholding Tax pursuant to this Indenture, and if the Swiss Available Amount is not fully utilized, such Swiss Obligor shall be required to pay, directly or by way of use of the proceeds of enforcement, an additional amount so that after making any required deduction of Swiss Withholding Tax the aggregate net amount paid to the beneficiary, directly or by way of use of the proceeds of enforcement, is equal to the amount which would have been paid if no deduction of Swiss Withholding Tax had been required. If a refund is made to a beneficiary, such beneficiary shall transfer the refund so received to the Swiss Obligor, subject to any right of set-off of such beneficiary pursuant to this Indenture or the other Finance Documents and subject to not being in a less favorable net after-tax position than the beneficiary would have been in if the Swiss Withholding Tax had not been required in the first instance.

111

(c) A Guarantee as to any Guarantor shall terminate and be of no further force or effect and such Guarantor shall be deemed to be automatically released from all obligations under this Article 10 upon:

(i) the sale, disposition, exchange or other transfer (including through merger, consolidation, amalgamation or otherwise) of the Capital Stock of the applicable Guarantor if (i) such sale, disposition, exchange or other transfer is made to a Person who is not the Issuer or a Restricted Subsidiary in a manner not in violation of this Indenture and (ii) after giving effect to such sale, disposition, exchange or other transfer, such Guarantor is no longer a Restricted Subsidiary;

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

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

SECTION 10.03. Successors and Assigns . This Article 10 shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of the Trustee, the Collateral Agent and the Holders and their successors and assigns and, in the event of any transfer or assignment of rights by any Holder, the Collateral Agent or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 10.04. No Waiver . Neither a failure nor a delay on the part of the Trustee, the Collateral Agent or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee, the Collateral Agent and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits that any of them 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 Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 10.06. Execution of Supplemental Indenture for Future Guarantors . Each Person that is required to become a Guarantor after the Issue Date pursuant to Section 4.10 shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit C hereto pursuant to which such Person shall become a Guarantor under this Article 10 and shall

112

guarantee the Guaranteed Obligations. Concurrently with the execution and delivery of such supplemental indenture, the Issuer shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Person and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Guarantee of such Guarantor is a legal, valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms or to such other matters as the Trustee may reasonably request.

SECTION 10.07. No Impairment . The failure to endorse a Guarantee on any Security shall not affect or impair the validity thereof. If an Officer whose signature is on this Indenture or the notation of Guarantee no longer holds that office at the time the Trustee authenticates such Security, the Guarantee shall be valid nevertheless.

ARTICLE 11

SECURITY DOCUMENTS

SECTION 11.01. Collateral and Security Documents . The due and punctual payment of the principal of and interest on the Securities when and as the same shall be due and payable, whether on an Payment Date, at Stated Maturity, or by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of and interest on the Securities and performance of all other Guaranteed Obligations of the Issuer and the Guarantors to the Holders, the Trustee or the Collateral Agent under this Indenture, the Securities, the Intercreditor Agreements and the Security Documents, according to the terms hereunder or thereunder, shall be secured as provided in the Security Documents, which define the terms of the Liens that secure the Guaranteed Obligations, subject to the terms of the Intercreditor Agreements. The Trustee and the Issuer hereby acknowledge and agree that the Collateral Agent holds the Notes Collateral in trust for the benefit of the Trustee and the Holders, in each case pursuant to the terms of the Security Documents and the Intercreditor Agreements. Each Holder, by accepting a Security, appoints U.S. Bank National Association as Collateral Agent and consents and agrees to the terms of the Security Documents (including the provisions providing for the possession, use, release and foreclosure of Notes Collateral) and the Intercreditor Agreements as the same may be in effect or may be amended from time to time in accordance with their respective terms and this Indenture, and authorizes and directs the Trustee to enter into the Security Documents and the Intercreditor Agreements and to bind the Holders to the terms thereof and to perform its obligations and exercise its rights thereunder in accordance therewith. The Issuer shall deliver to the Trustee (if it is not then also appointed and serving as Collateral Agent) copies of all documents delivered to the Collateral Agent pursuant to the Security Documents, and will do or cause to be done all such acts and things as may be reasonably required by the next sentence of this Section 11.01, to assure and confirm to the Trustee and the Collateral Agent the Liens on the Notes Collateral contemplated hereby, by the Security Documents or by any part thereof, as from time to time constituted, so as to render the same available for the security and benefit of this Indenture and of the Securities secured hereby, according to the intent and purposes herein expressed. The Issuer shall take, and shall cause the Guarantors to take, any and all actions reasonably required to cause the Security Documents to create and maintain at all times, as

113

security for the Obligations of the Issuer and the Guarantors hereunder, a valid and enforceable perfected Lien on all of the Notes Collateral (subject to the terms of the Security Documents and the Intercreditor Agreements), in favor of the Collateral Agent for the benefit of the Trustee and the Holders under the Security Documents. Notwithstanding anything to the contrary in this Indenture or any of the Security Documents, in no event shall the Collateral Agent be responsible for, or have any duty or obligation with respect to, the recording, filing, registering, perfection, protection or maintenance of the security interests or other Liens intended to be created by this Indenture or the Security Documents (including the filing or continuation of any UCC financing or continuation statements or similar documents or instruments), nor shall the Collateral Agent be responsible for, and the Collateral Agent makes no representation regarding, the validity, effectiveness or priority of any of the Security Documents or the security interests or other Liens intended to be created thereby.

SECTION 11.02. Release of Collateral .

(a) Subject to Section 11.02(b) and 11.03, the Notes Collateral may be released from the Lien and security interest created by the Security Documents at any time or from time to time in accordance with the provisions of the Security Documents or the Intercreditor Agreements or as provided by Section 11.08 or by this Section 11.02(a). The Issuer and the Guarantors will be entitled to a release of assets included in the Notes Collateral from the Liens securing the Securities, and the Trustee shall release, or instruct the Collateral Agent to release, as applicable, the same from such Liens at the Issuer’s sole cost and expense, under one or more of the following circumstances:

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

(ii) in the case of a Guarantor that is released from its Guarantee with respect to the Securities in accordance with this Indenture, the release of the Capital Stock (to the extent transferred to a party other than an Issuer or a Guarantor in a transaction not prohibited under Section 4.06) and property and assets of such Guarantor; provided, however, that if the Issuer or its Restricted Subsidiaries retains any Capital Stock of the applicable Guarantor following a sale, disposition, exchange or other transfer of the Capital Stock of such Guarantor, the Liens on such retained Capital Stock shall not be released;

(iii) in respect of the property and assets of a Restricted Subsidiary, upon the designation of such Restricted Subsidiary to be an Unrestricted Subsidiary in accordance with Section 4.04 and the definition of “Unrestricted Subsidiary”;

(iv) in respect of the ABL Collateral (x) to the extent any first-priority liens on such ABL Collateral are released by the First Lien Agent in connection

114

with a disposition of ABL Collateral to the extent permitted or not prohibited under Section 4.06 (except with respect to any proceeds of such disposition that remain after satisfaction in full of the First Priority Lien Obligations secured by such ABL Collateral) or (y) in accordance with an Intercreditor Agreement; or

(v) pursuant to an amendment, supplement or waiver in accordance with Article 9.

Notwithstanding the existence of any Event of Default, the junior lien on the ABL Collateral securing the Securities shall terminate and be released automatically to the extent the first-priority liens on the ABL Collateral are released by the First Lien Agent in connection with a sale, transfer or disposition of ABL Collateral that is either not prohibited under this Indenture or occurs in connection with the foreclosure of, or other exercise of remedies with respect to, such ABL Collateral by the First Lien Agent (except with respect to any proceeds of such sale, transfer or disposition that remain after satisfaction in full of the First Priority Lien Obligations).

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

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

SECTION 11.03. Permitted Releases Not To Impair Lien . The release of any Notes Collateral from the terms hereof and of the Security Documents or the release of, in whole or in part, the Liens created by the Security Documents, will not be deemed to impair the security under this Indenture in contravention of the provisions hereof if and to the extent the Notes Collateral or Liens are released pursuant to (x) the applicable Security Documents and the terms of this Article 11 or (y) the Intercreditor Agreements. Each of the Holders acknowledges that a release of Notes Collateral or a Lien in accordance with the terms of the Security Documents and the Intercreditor Agreements and of this Article 11 will not be deemed for any purpose to be in contravention of the terms of this Indenture.

SECTION 11.04. Suits To Protect the Collateral . Subject to the provisions of Article 7 and the Intercreditor Agreements, the Trustee in its sole discretion and without the consent of the Holders, on behalf of the Holders, may or may direct the Collateral Agent to take all actions it deems necessary or appropriate in order to:

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

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

115

Subject to the provisions of the Security Documents and the Intercreditor Agreements, the Trustee shall have the power (but not the obligation) to institute and to maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Notes Collateral by any acts that may be unlawful or in violation of any of the Security Documents or this Indenture, and such suits and proceedings as the Trustee, in its sole discretion, may deem expedient to preserve or protect its interests and the interests of the Holders in the Notes Collateral (including the power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the Lien on the Notes Collateral or be prejudicial to the interests of the Holders or the Trustee).

SECTION 11.05. Authorization of Receipt of Funds by the Trustee Under the Security Documents . Subject to the provisions of the Intercreditor Agreements, the Trustee is authorized (a) to receive any funds for the benefit of the Holders distributed under the Security Documents and (b)to make further distributions of such funds to the Holders according to the provisions of this Indenture.

SECTION 11.06. Purchaser Protected . In no event shall any purchaser in good faith of any property purported to be released hereunder be bound to ascertain the authority of the Collateral Agent or the Trustee to execute the release or to inquire as to the satisfaction of any conditions required by the provisions hereof for the exercise of such authority or to see to the application of any consideration given by such purchaser or other transferee; nor shall any purchaser or other transferee of any property or rights permitted by this Article 11 to be sold be under any obligation to ascertain or inquire into the authority of the Issuer or the applicable Guarantor to make any such sale or other transfer.

SECTION 11.07. Powers Exercisable by Receiver or Trustee . In case the Notes Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 11 upon the Issuer or a Guarantor with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Issuer or a Guarantor or of any officer or officers thereof required by the provisions of this Article 11; and if the Trustee shall be in the possession of the Notes Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee.

SECTION 11.08. Release Upon Termination of the Issuer ’ s Obligations . In the event that the Issuer delivers to the Trustee an Officers’ Certificate certifying that (i) payment in full of the principal of, together with premium, if any, and accrued and unpaid interest on, the Securities and all other Obligations with respect to the Securities under this Indenture, the Guarantees and the Security Documents that are due and payable at or prior to the time such principal, together with premium, if any, and accrued and unpaid interest (including additional interest, if any), are paid, (ii) all the Obligations under this Indenture, the Securities and the Security Documents have been satisfied and discharged by complying with the provisions of

116

Article 8 or (iii) the Issuer shall have exercised its legal defeasance option or its covenant defeasance option, in each case in compliance with the provisions of Article 8, the Trustee shall deliver to the Issuer and the Collateral Agent a notice stating that the Trustee, on behalf of the Holders, disclaims and gives up any and all rights it has in or to the Notes Collateral (other than with respect to funds held by the Trustee pursuant to Article 8), and any rights it has under the Security Documents, and upon receipt by the Collateral Agent of such notice, the Collateral Agent shall be deemed not to hold a Lien in the Notes Collateral on behalf of the Trustee and shall do or cause to be done all acts reasonably requested by the Issuer to release such Lien as soon as is reasonably practicable.

SECTION 11.09. Collateral Agent .

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

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

117

(c) If the Issuer or any Guarantors Incur any obligations in respect of any First Priority Lien Obligations at any time when no intercreditor agreement with respect thereto is in effect or at any time when Indebtedness constituting First Priority Lien Obligations entitled to the benefit of an existing intercreditor agreement is concurrently retired, the Issuer shall deliver to the Collateral Agent an Officers’ Certificate so stating and requesting the Collateral Agent to enter into an Intercreditor Agreement in favor of a designated agent or representative for the holders of the First Priority Lien Obligations so Incurred, and the Trustee and the Collateral Agent shall (and are hereby authorized and directed to) enter into such Intercreditor Agreement, bind the Holders on the terms set forth therein and perform and observe their obligations thereunder.

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

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

(f) No provision of this Indenture or any Security Document shall require the Collateral Agent (or the Trustee) to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or thereunder or to take or omit to take any action hereunder or thereunder or take any action at the request or direction of Holders (or the Trustee in the case of the Collateral Agent) if it shall have reasonable grounds for believing that repayment of such funds is not assured to it. Notwithstanding anything to the contrary contained in this Indenture, the Intercreditor Agreements or the Security Documents, in the event the Collateral Agent is entitled or required to commence an action to foreclose or otherwise exercise its remedies to acquire control or possession of the Notes Collateral, the Collateral Agent shall not be required to commence any such action, exercise any remedy, inspect or conduct any studies of any property or take any such other action if the Collateral Agent has determined that the Collateral Agent may incur personal liability as a result of the presence at, or release on or from, the Notes Collateral or such property of any hazardous substances unless the Collateral Agent has received security or indemnity from the Holders in an amount and in a form all satisfactory to the Collateral Agent in its sole discretion, protecting the Collateral Agent from all such liability. The Collateral Agent shall at any time be entitled to cease taking any action described in this Section 11.09 (f) if it no longer reasonably deems any indemnity, security or undertaking from the Issuer or the Holders to be sufficient.

118

(g) The Collateral Agent shall not be responsible in any manner to any of the Trustee or any Holder for the validity, effectiveness, genuineness, enforceability or sufficiency of this Indenture, the Security Documents or the Intercreditor Agreements or for any failure of the Issuer, any Guarantor or any other party to this Indenture, the Security Documents or the Intercreditor Agreements to perform its obligations hereunder or thereunder. The Collateral Agent shall not be under any obligation to the Trustee or any Holder to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Indenture, the Security Documents or the Intercreditor Agreements or to inspect the properties, books or records of the Issuer or the Guarantors.

(h) The parties hereto and the Holders hereby agree and acknowledge that the Collateral Agent shall not assume, be responsible for or otherwise be obligated for any liabilities, claims, causes of action, suits, losses, allegations, requests, demands, penalties, fines, settlements, damages (including foreseeable and unforeseeable), judgments, expenses and costs (including any remediation, corrective action, response, removal or remedial action, or investigation, operations and maintenance or monitoring costs, for personal injury or property damages, real or personal) of any kind whatsoever, pursuant to any environmental law as a result of this Indenture, the Intercreditor Agreements or the Security Documents or any actions taken pursuant hereto or thereto. Further, the parties hereto and the Holders hereby agree and acknowledge that, in the exercise of its rights under this Indenture, the Intercreditor Agreements and the Security Documents, the Collateral Agent may hold or obtain indicia of ownership primarily to protect the security interest of the Collateral Agent in the Notes Collateral and that any such actions taken by the Collateral Agent shall not be construed as or otherwise constitute any participation in the management of such Notes Collateral.

(i) Upon the receipt by the Collateral Agent of a written request of the Issuer signed by two Officers pursuant to this Section 11.09(i) (a “Security Document Order”), the Collateral Agent is hereby authorized to execute and enter into, and shall execute and enter into, without the further consent of any Holder or the Trustee, any Security Document to be executed after the Issue Date. Such Security Document Order shall (i) state that it is being delivered to the Collateral Agent pursuant to, and is a Security Document Order referred to in, this Section 11.09(i) and (ii) instruct the Collateral Agent to execute and enter into such Security Document. Any such execution of a Security Document shall be at the direction and expense of the Issuer, upon delivery to the Collateral Agent of an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent to the execution and delivery of such Security Document have been satisfied. The Holders, by their acceptance of the Securities, hereby authorize and direct the Collateral Agent to execute such Security Documents.

(j) The Collateral Agent’s resignation or removal shall be governed by provisions equivalent to Section 7.07(a), Section 7.07(b), Section 7.07(c), Section 7.07(d) and Section 7.07(f).

(k) The Collateral Agent shall be entitled to all of the protections, immunities, indemnities, rights and privileges of the Trustee set forth in this Indenture, and all such protections, immunities, indemnities, rights and privileges shall apply to the Collateral Agent in its roles under any Security Document or the Intercreditor Agreements, whether or not expressly stated therein.

(l) In relation to the Swiss Security Documents the following additional provisions shall apply:

(i) The Collateral Agent holds:

(A) any security created or expressed to be created under or pursuant to the Swiss Security Documents by way of a security assignment ( Sicherungsabtretung ) or transfer for security purposes ( Sicherungsübereignung ) or any other non-accessory ( nicht akzessorische ) security;

(B) the benefit of this Section 11.09(l); and

(C) any proceeds and other benefits of such security as fiduciary ( treuhänderisch ) in its own name but for the account of any Holder of Securities, the Trustee and any other Secured Party (as defined in the Collateral Agreement) which have the benefit of such security in accordance with the Finance Documents and the respective Swiss Security Documents;

(ii) each Holder of Securities, the Trustee and any other Secured Party (as defined in the Collateral Agreement) hereby authorizes the Collateral Agent:

(A) to accept and execute as its direct representative ( direkter Stellvertreter ) any Swiss law pledge or any other Swiss law accessory ( akzessorische ) security created or expressed to be created under or pursuant to the Swiss Security Documents for the benefit of such Holder of Securities, the Trustee and any other Secured Party (as defined in the Collateral Agreement) and hold, administer and, if necessary, enforce any such security on behalf of each relevant Secured Party (as defined in the Collateral Agreement) which has the benefit of such security;

120

(iii) the Issuer and each Guarantor hereby authorize the Collateral Agent, when acting in its capacity as creditor of the Parallel Debt claims as set forth in Section 11.10, to hold:

(C) the benefit of this Section 11.09(l) and of the Parallel Debt claims, as creditor in its own right but for the benefit of the Holders of Securities, the Trustee or any other Secured Party (as defined in the Collateral Agreement) in accordance with this Indenture.

SECTION 11.10. Parallel Debt . Notwithstanding any other provision of this Indenture, and solely for the purpose of security granted under the Swiss Security Documents, the Issuer and the Guarantors hereby irrevocably and unconditionally undertake (by way of an abstract acknowledgment of debt ( abstraktes Schuldanerkenntnis )) to pay to the Collateral Agent as creditor in its own right, and not as a representative of the Holders of Securities or the Trustee, amounts equal to any amounts owing from time to time by such obligor to any Holder of Securities, the Trustee and any other Secured Party (as defined in the Collateral Agreement), this Indenture, the Securities or any other Indenture Document (as defined in the Collateral Agreement) (the “Finance Documents”) as and when, and in the currency of, those amounts are due for payment under the Finance Documents.

The Issuer and each Guarantor acknowledge that their obligations under this Section 11.10 are several and are separate and independent from, and shall not in any way limit or affect, the corresponding obligations of such obligor to any Holder of Securities, the Trustee and any other Secured Party (as defined in the Collateral Agreement), as applicable (its “Corresponding Debt”), nor shall the amounts for which the Issuer and each Guarantor is liable under this Section 11.10 (its “Parallel Debt”) be limited or affected in any way by its Corresponding Debt; provided, that, (i) the Parallel Debt shall be decreased to the extent that its Corresponding Debt has been irrevocably paid or discharged; and (ii) the Corresponding Debt of the Issuer and each Guarantor shall be decreased to the extent that its Parallel Debt has been irrevocably paid or discharged, but further provided that the Corresponding Debt shall not be decreased, if it is effected by virtue of any set-off, counterclaim or similar defense invoked by the Issuer or a Guarantor vis-à-vis the Trustee.

All monies received or recovered by the Collateral Agent pursuant to this Section 11.10 and all amounts received or recovered by the Collateral Agent from or by the enforcement of any security interest granted to secure the Parallel Debt, shall be applied in accordance with the Finance Documents.

121

Without limiting or affecting the Collateral Agent’s rights against the Issuer or the Guarantors the Issuer and each Guarantor acknowledges that (i) nothing in this Section 11.10 shall impose any obligation on the Collateral Agent to advance any sum to the Issuer or the Guarantors or otherwise under the Finance Documents, except in its capacity as Holder of Securities (if applicable); and (ii) for the purpose of any vote taken any Finance Document, the Collateral Agent shall not be regarded as having any participation or commitment other than those which it has in its capacity as a Holder of Securities (if applicable).

SECTION 12.14. Currency of Account; Conversion of Currency; Currency Exchange Restrictions .

(a) U.S. Dollars are the sole currency of account and payment for all sums payable by the Issuer and the Guarantors under or in connection with the Securities, the Guarantees and this Indenture, including damages related thereto. Any amount received or recovered in a currency other than U.S. Dollars by a Holder (whether as a result of, or as a result of the enforcement of, a judgment or order of a court of any jurisdiction, in the winding-up or dissolution of the Issuer or otherwise) in respect of any sum expressed to be due to it from the Issuer or a Guarantor shall only constitute a discharge to the Issuer or any such Guarantor to the extent of the U.S. Dollar amount, which the recipient is able to purchase with the amount so received or recovered in that other currency on the date of that receipt or recovery (or, if it is not practicable to make that purchase on that date, on the first date on which it is practicable to do so). If that U.S. Dollar amount is less than the U.S. Dollar amount expressed to be due to the recipient under the applicable Securities, the Issuer and the Guarantors shall indemnify it against any loss sustained by it as a result as set forth in Section 12.14(b). In any event, the Issuer and the Guarantors shall indemnify the recipient against the cost of making any such purchase. For the purposes of this Section 12.14, it will be sufficient for the Holder of a Security to certify in a satisfactory manner (indicating sources of information used) that it would have suffered a loss had an actual purchase of U.S. Dollars been made with the amount so received in that other currency on the date of receipt or recovery

125

(or, if a purchase of U.S. Dollars on such date had not been practicable, on the first date on which it would have been practicable, it being required that the need for a change of date be certified in the manner mentioned above).

(b) The Issuer and the Guarantors, jointly and severally, covenant and agree that the following provisions shall apply to conversion of currency in the case of the Securities, the Guarantees and this Indenture:

(i) The following apply:

(A) If for the purpose of obtaining judgment in, or enforcing the judgment of, any court in any country, it becomes necessary to convert into a currency (the “Judgment Currency”) an amount due in any other currency (the “Base Currency”), then the conversion shall be made at the rate of exchange prevailing on the Business Day before the day on which the judgment is given or the order of enforcement is made, as the case may be (unless a court shall otherwise determine).

(B) If there is a change in the rate of exchange prevailing between the Business Day before the day on which the judgment is given or an order of enforcement is made, as the case may be (or such other date as a court shall determine), and the date of receipt of the amount due, the Issuer and the Guarantors will pay such additional (or, as the case may be, such lesser) amount, if any, as may be necessary so that the amount paid in the Judgment Currency when converted at the rate of exchange prevailing on the date of receipt will produce the amount in the Base Currency originally due.

(ii) In the event of the winding-up of the Issuer or any Guarantor at any time while any amount or damages owing under the Securities, the Guarantees and this Indenture, or any judgment or order rendered in respect thereof, shall remain outstanding, the Issuer and the Guarantors shall indemnify and hold the Holders and the Trustee harmless against any deficiency arising or resulting from any variation in rates of exchange between (1) the date as of which the non-U.S. currency equivalent of the amount due or contingently due under the Securities, the Guarantees and this Indenture (other than under this subsection (b)(ii)) is calculated for the purposes of such winding-up and (2) the final date for the filing of proofs of claim in such winding-up. For the purpose of this subsection (b)(ii), the final date for the filing of proofs of claim in the winding-up of the Issuer or any Guarantor shall be the date fixed by the liquidator or otherwise in accordance with the relevant provisions of applicable law as being the latest practicable date as at which liabilities of the Issuer or such Guarantor may be ascertained for such winding-up prior to payment by the liquidator or otherwise in respect thereto.

(c) The obligations contained in subsections (a), (b)(i)(B) and (b)(ii) of this Section 12.14 shall constitute separate and independent obligations from the other obligations

126

of the Issuer and the Guarantors under this Indenture, shall give rise to separate and independent causes of action against the Issuer and the Guarantors, shall apply irrespective of any waiver or extension granted by any Holder or the Trustee or either of them from time to time and shall continue in full force and effect notwithstanding any judgment or order or the filing of any proof of claim in the winding-up of the Issuer or any Guarantor for a liquidated sum in respect of amounts due hereunder (other than under subsection (b)(ii) above) or under any such judgment or order. Any such deficiency as aforesaid shall be deemed to constitute a loss suffered by the Holders or the Trustee, as the case may be, and no proof or evidence of any actual loss shall be required by the Issuer or any Guarantor or the liquidator or otherwise or any of them. In the case of subsection (b)(ii) above, the amount of such deficiency shall not be deemed to be reduced by any variation in rates of exchange occurring between the said final date and the date of any liquidating distribution.

(d) The term “rate(s) of exchange” shall mean the rate of exchange quoted by Reuters at 10:00 a.m. (New York City time) for spot purchases of the Base Currency with the Judgment Currency other than the Base Currency referred to in subsections (b)(i) and (b)(ii) above and includes any premiums and costs of exchange payable.

SECTION 12.15. Intercreditor Agreement Governs .

(a) The terms of this Indenture are subject to the Intercreditor Agreements. Each Holder, by its acceptance of a Security, (i) consents to the subordination of Liens provided for in the Intercreditor Agreements, (ii) agrees that it will be bound by and will take no actions contrary to the provisions of the Intercreditor Agreements and (iii) authorizes and instructs the Trustee to enter into the Intercreditor Agreements and the Collateral Agent to enter into the Intercreditor Agreements as Noteholder Collateral Agent (as defined therein) and to bind such Holder to the terms thereof, and, in each case, on behalf of such Holder. The foregoing provisions are intended as an inducement to the other lenders to the Issuer or any Guarantors acting as a secured party under the Intercreditor Agreements to extend credit and such lenders are intended third party beneficiaries of such provisions and the provisions of the Intercreditor Agreements. Pursuant to the authorization of each Holder, the Trustee and the Collateral Agent hereby agree to enter into Intercreditor Agreements substantially in the form attached hereto as Exhibit D from time to time upon the request of the Issuer, when accompanied by an Officers’ Certificate and Opinion of Counsel confirming compliance with all conditions precedent set forth herein. To the extent the provisions of this Indenture conflict or are inconsistent with the Intercreditor Agreements, each Holder (by accepting a Security), the Trustee and the Collateral Agent consents and agrees that the Intercreditor Agreements will control.

(b) Notwithstanding anything to the contrary herein, in this Indenture or in any Security Document or any ABL Document (as such term is defined in the Intercreditor Agreements), the Issuer and the Guarantors shall not be required to act or refrain from acting (i) pursuant to this Indenture or any Security Document solely with respect to any ABL Collateral in any manner that would cause a default under any ABL Document, or (ii) pursuant to any ABL Document solely with respect to any Noteholder First Lien Collateral in any manner that would cause a default under this Indenture or any Security Document. For avoidance of doubt, and for the purposes of this paragraph only, the terms Security Document and ABL Document do not include the Intercreditor Agreements.

127

SECTION 12.16. Tax Matters .

(a) The Issuer has entered into this Indenture, and the Securities will be issued, with the intention that, for all tax purposes, the Securities will qualify as indebtedness. The Issuer, by entering into this Indenture, and each Holder and beneficial owner of Securities, agree to treat the Securities as indebtedness for all tax purposes.

(b) The Issuer shall instruct DTC to code interest on the Securities held by DTC as “foreign source” income.

SECTION 12.17. USA PATRIOT Act . The parties hereto acknowledge that in accordance with Section 326 of the USA PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies each Person that establishes a relationship or opens an account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the USA PATRIOT Act.

Initially, U.S. Bank National Association (the “Trustee”) will act as Paying Agent and Registrar. The Issuer or any of its Wholly Owned Restricted Subsidiaries may act as Paying Agent or Registrar.

The Issuer issued the Securities under the Indenture dated as of October 14, 2016 (the “Indenture”) among the Issuer, the guarantors that may be party thereto from time to time, the Trustee and the Collateral Agent. The terms of the Securities include those stated in the Indenture. Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all terms and provisions of the Indenture, and the Holders are referred to the Indenture for a statement of such terms and provisions. If and to the extent that any provision of the Securities limits, qualifies or conflicts with a provision of the Indenture, such provision of the Indenture shall control.

The Securities are senior secured obligations of the Issuer. This Security is one of the Securities referred to in the Indenture. The Securities are treated as a single class of securities under the Indenture. The Indenture imposes certain limitations on the ability of the Issuer and its Restricted Subsidiaries to, among other things, make certain Investments and other Restricted Payments, pay dividends and other distributions, incur Indebtedness, enter into consensual restrictions upon the payment of certain dividends and distributions by such Restricted Subsidiaries, issue or sell shares of capital stock of the Issuer and such Restricted Subsidiaries, enter into or permit certain transactions with Affiliates, create or incur Liens and make Asset Sales. The Indenture also imposes limitations on the ability of the Issuer and each Guarantor to consolidate or merge with or into any other Person or convey, transfer or lease all or substantially all of their property.

To guarantee the due and punctual payment of the principal of and interest on the Securities and all other amounts payable by the Issuer under the Indenture and the Securities when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Securities and the Indenture, the Guarantors have, jointly and severally, irrevocably and unconditionally guaranteed the Guaranteed Obligations on a senior secured basis pursuant to the terms of the Indenture.

The Issuer may redeem the Securities at its option, in whole at any time or in part from time to time, on any Business Day specified by the Issuer prior to October 14, 2018 (the “First Call Date”), on not less than 30 days’ nor more than 60 days’ prior written notice delivered

A-5

to each Holder, at a redemption price equal to 100% of the principal amount of the Securities being redeemed plus the Applicable Premium, plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Payment Date).

The Issuer may redeem the Securities at its option, in whole at any time or in part from time to time, on any Business Day specified by the Issuer on or after the First Call Date, on not less than 30 days’ nor more than 60 days’ prior written notice delivered to each Holder, at the following redemption prices (expressed as a percentage of outstanding principal amount of the Securities being redeemed), 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 Payment Date), for the following periods:

Notwithstanding the foregoing, in connection with any tender offer for all of the outstanding Securities at a price of at least 100% of the principal amount of the Securities tendered, plus accrued and unpaid interest thereon to, but excluding, the applicable tender settlement date, if holders of not less than 90% in aggregate principal amount of the outstanding Securities validly tender and do not withdraw such Securities in such tender offer and the Issuer, or any third party making such tender offer in lieu of the Issuer, purchases all of the Securities validly tendered and not withdrawn by such holders, the Issuer or such third party will have the right upon not less than 15 nor more than 60 days’ prior notice to the Holders (with a copy to the Trustee), given not more than 30 days following such purchase date, to redeem all Securities that remain outstanding following such purchase at a price equal to the price offered to each other holder in such tender offer plus, to the extent not included in the tender offer payment, accrued and unpaid interest, if any, thereon, to, but excluding, the redemption date.

Notice of any redemption may, at the Issuer’s discretion, be subject to one or more conditions precedent, including the receipt by the Trustee, on or prior to the redemption date, of money sufficient to pay the principal of, and premium, if any, and interest on, the Securities being redeemed.

Except as otherwise provided in paragraph 5, written notice of redemption pursuant to paragraph 5 will be provided at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed. Securities in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000. If money sufficient to pay the redemption price of and accrued and unpaid interest on all Securities (or portions thereof) to be redeemed on the redemption date is deposited with a Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after such date, interest ceases to accrue on such Securities (or such portions thereof) called for redemption.

A-6

The Securities are not subject to any sinking fund.

Upon the occurrence of a Change of Control, each Holder shall have the right, subject to certain conditions specified in the Indenture, to cause the Issuer to repurchase all or any part of such Holder’s Securities at a purchase price in cash equal to 101% of the principal balance thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of the Holders of record on the relevant Record Date to receive interest due on the related Payment Date), as provided in, and subject to the terms of, the Indenture.

In accordance with, and subject to the terms of, Section 4.06 of the Indenture, the Issuer will be required to offer to purchase Securities upon the occurrence of certain Asset Sale events.

The Securities will be secured by the Notes Collateral on the terms and subject to the conditions set forth in the Indenture and the Security Documents. The Collateral Agent holds the Notes Collateral in trust for the benefit of the Trustee and the Holders, in each case pursuant to the Security Documents and the Intercreditor Agreements. Each Holder, by accepting this Security, consents and agrees to the terms of the Security Documents (including the provisions providing for the foreclosure and release of Notes Collateral) and the Intercreditor Agreements as the same may be in effect or may be amended from time to time in accordance with their terms and the Indenture and authorizes and directs each of the Trustee and the Collateral Agent to enter into the Security Documents and the Intercreditor Agreements, and to perform its obligations and exercise its rights thereunder in accordance therewith.

The Securities are in registered form, without coupons, in minimum denominations of $50,000 and any integral multiple of $1,000 in excess thereof. The registration of transfer of or exchange of Securities shall be done in accordance with the Indenture. Upon any registration of transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes 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 to transfer or exchange any Securities for a period of 15 days prior to a selection of Securities to be redeemed.

Subject to Section 2.14 of the Indenture, the registered Holder of this Security shall be treated as the owner of it for all purposes.

A-7

If money for the payment of principal or interest remains unclaimed for two years, the Trustee and a Paying Agent shall pay the money back to the Issuer at its written request unless an abandoned property law designates another Person. After any such payment, the Holders entitled to the money must look to the Issuer for payment as general creditors and the Trustee and Paying Agent shall have no further liability with respect to such monies.

Subject to certain conditions set forth in the Indenture, the Issuer at any time may terminate some of or all its obligations under the Securities and the Indenture if the Issuer deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be.

Subject to certain exceptions set forth in the Indenture, (x) the Indenture, the Securities, the Guarantees, any Security Document or any Intercreditor Agreement may be amended or supplemented, and any provision thereof may be waived, with the written consent of the Holders of a majority in principal amount of the Securities then outstanding (voting as a single class) and (y) any past default or compliance with any provisions of such documents may be waived with the written consent of the Holders of a majority in principal amount of the Securities then outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Issuer, the Collateral Agent, the Guarantors and the Trustee may amend or supplement the Indenture, the Securities, the Guarantees, any Security Document or any Intercreditor Agreement (i) to cure any ambiguity, omission, mistake, defect or inconsistency; (ii) to provide for the assumption by a Successor Company of the obligations of the Issuer under the Indenture and the Securities in accordance with the terms of the Indenture; (iii) to provide for the assumption by a Successor Guarantor of the obligations of a Guarantor under the Indenture and its Guarantee in accordance with the terms of the Indenture; (iv) 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 Sections 871(h)(2)(B) and 881(c)(2)(B) of the Code and United States Treasury Regulation Section 5f.103-1(c)); (v) to add additional Guarantees with respect to the Securities and to release any Guarantor from its Guarantee in accordance with the terms of the Indenture; (vi) to add to the covenants of the Issuer for the benefit of the Holders or to surrender any right or power conferred in the Indenture upon the Issuer; (vii) to evidence or provide for the acceptance of appointment under the Indenture of a successor trustee or a successor collateral agent; (viii) to make any change that does not adversely affect the rights of any Holder in any material respect; (ix) to add additional assets as Notes Collateral to secure the Securities; (x) to release Notes Collateral from the Lien pursuant to the Indenture, the Security Documents and the Intercreditor Agreements when permitted or required by the Indenture, the Security Documents or the Intercreditor Agreements; (xi) to modify the Security Documents or the Intercreditor Agreements (a) to secure additional extensions of credit and add additional secured creditors holding First Priority Lien Obligations so long as such First Priority Lien Obligations are not prohibited by the provisions of the Indenture, (b) as provided for in provisions comparable to Section 2.11(b) of the form of

A-8

Intercreditor Agreement attached as Exhibit D to the Indenture or (c) to add the Issuer or any Guarantor as a party to any Intercreditor Agreement to the extent such party Incurs any Secured Indebtedness that constitutes First Priority Lien Obligations in accordance with the terms of the Indenture or to remove the Issuer or any Guarantor as a party to any Intercreditor Agreement to the extent such party ceases to be bound by any and all First Priority Lien Obligations; or (xii) to comply with the rules of any applicable securities depositary.

If an Event of Default (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization with respect to the Issuer) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding Securities by notice to the Issuer may, and if such notice is given by the Holders such notice shall be given to the Issuer and the Trustee, declare that the principal of, and the premium, if any, and accrued but unpaid interest on, all the Securities is due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization with respect to the Issuer occurs, the principal of, and the premium, if any, and accrued but unpaid 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. Under certain circumstances, the Holders of a majority in principal amount of the Securities may rescind any such acceleration with respect to the Securities and its consequences.

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 the Indenture or the Securities unless (i) such Holder gives the Trustee written notice stating that an Event of Default is continuing, (ii) the Holders of at least 25% in principal amount of the then outstanding Securities make a written request to the Trustee to pursue the remedy, (iii) such Holder or Holders offer to the Trustee security or indemnity satisfactory to it against any loss, liability or expense, (iv) the Trustee does not comply with such request within 60 days after the receipt of the request and the offer of security or indemnity and (v) the Holders of a majority in principal amount of the then outstanding Securities do not give the Trustee a direction inconsistent with such request during such 60-day period. Subject to certain restrictions set forth in the Indenture, 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. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or, subject to the Indenture, that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. Prior to taking any action under the Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

Subject to certain limitations imposed by the Indenture, 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 the Issuer or its Affiliates with the same rights it would have if it were not Trustee.

A-9

No director, officer, employee, manager, member, partner, incorporator or holder of any Equity Interests in the Issuer or in any Guarantor, as such, shall have any liability for any obligations of the Issuer or the Guarantors under the Securities, the Indenture, the Guarantees, the Security Documents or the Intercreditor Agreements or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Securities by accepting a Security waives and releases all such liability.
