SECTION 2.02.        Execution and Authentication .  An Officer shall sign the Securities for the Company 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, upon a written order of the Company signed by an Officer of the Company, together with the other documents required by Sections 14.02 and 14.03, shall authenticate Securities for original issue on the Issue Date in the aggregate principal amount not to exceed $525,000,000.  Such written order of the Company shall specify the amount of Securities to be authenticated and the date on which the original issue of Securities is to be authenticated.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the Securities.  Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so.  Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.  An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate reasonable compensation therefor pursuant to Section 7.06.  The Company may change the Paying Agent or Registrar without prior notice to the Holders.  The Company or any of its Affiliates incorporated or organized within The United States of America may act as Paying Agent, Registrar, co-registrar or transfer agent.

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

The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Securities.

SECTION 2.04.        Paying Agent To Hold Money in Trust .  Prior to each due date of the principal of and interest on any Security, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due.  The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders of Securities or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee of any default by the Company in making any such payment.  If the Company or any of its Affiliates acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund.  The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent.  Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.05.        Lists of Holders of Securities .  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 of Securities.  If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least five Business Days before each interest payment date with respect to Securities and at such other times as the Trustee may reasonably 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 of Securities.

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

Neither the Trustee nor any agent of the Trustee shall have any responsibility for any actions taken or not taken by the Depositary.

SECTION 2.07.        Replacement Securities .  If any mutilated Security is surrendered to the Trustee or either the Company or the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Security, the Company shall issue and the Trustee, upon receipt of evidence of authentication in accordance with Section 2.02, shall authenticate a replacement Security if the Trustee’s requirements for replacement of Securities are met.  An indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any agent and any authenticating agent from any loss that any of them may suffer if a Security is replaced.  The Trustee and the Company each may charge such Holder for their expenses in replacing such Security.

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

SECTION 2.08.        Outstanding Securities .  Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding.

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.09.        Temporary Securities .  Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities.  Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities.  Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities.

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

SECTION 2.11.        Defaulted Interest .  If the Company defaults in a payment of principal, interest or any other amount on the Securities, the Company shall pay defaulted interest at the rate specified in the Securities (plus interest on such defaulted interest to the extent lawful) in any lawful manner.  The Company may pay the defaulted interest to the persons who are Holders of Securities on a subsequent special record date.  The Company shall fix or cause to be fixed any such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest.  At least 15 days before the special record date, the Company (or, upon written request of the Company, the Trustee in the name and at the expense of the Company) will send to each Holder of Securities

a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. The Trustee will have no duty whatsoever to determine whether any defaulted interest is payable or the amount thereof.

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

SECTION 6.02.        Acceleration of Maturity ; Rescission and Annulment .  If an Event of Default described in Section 6.01 (other than Event of Default specified in Section 6.01(f) or (g)) with respect to Securities at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount, if any, of the Outstanding Securities, declare the principal amount of all of the Securities and all interest thereon to be due and payable immediately, together with the Make-Whole Premium, if any, by a notice in writing to the Company (and to the Trustee if given by the Holders) and upon any such declaration such amounts shall become immediately due and payable.  Upon the occurrence of an Event of Default specified in Section 6.01(f) or (g), the principal amount of all of the Securities, all interest thereon, and the Make-Whole Premium, if any, shall automatically and immediately become due and payable.

For the avoidance of doubt, if the principal amount of the Securities is paid on or prior to May 15, 2021, the Make-Whole Premium provided under Section 3.08 hereof shall be paid, even if such payment is made following acceleration pursuant to this Section 6.02. The Company will pay the Make-Whole Premium, as compensation to the Holders for the loss of their investment opportunity and not as a penalty, whether or not an Event of Default specified in Section 6.01(f) or (g) has occurred and (if an Event of Default specified in Section 6.01(f) or (g) has occurred) without regard to whether the event causing such Event of Default is voluntary or involuntary, or whether payment occurs pursuant to a motion, plan of reorganization, or otherwise, and without regard to whether the Securities and other Notes Obligations are satisfied or released by foreclosure (whether or not by power of judicial proceeding), deed in lieu of foreclosure or by any other means.  Any premium payable pursuant to this Section 6.02 shall be presumed to be the liquidated damages sustained by each Holder as a result of the early repayment of the Securities and the Note Parties agree that it is reasonable under the circumstances currently existing.  EACH NOTE PARTY EXPRESSLY WAIVES (TO THE FULLEST EXTENT IT MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE MAKE-WHOLE PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION. The Company expressly agrees (to the fullest extent it may lawfully do so) that: (A) the Make-Whole Premium is reasonable and the product of an arm’s length transaction between sophisticated business people, ably represented by counsel; (B) the Make-Whole Premium shall be payable notwithstanding the then prevailing market rates at the time payment is made; (C) there has been a course of conduct between Holders and the Company giving specific consideration in this transaction for such agreement to pay the Make-Whole Premium; and (D) the Company shall be estopped hereafter from claiming differently than as agreed to in this paragraph. The Company expressly acknowledges that its agreement to pay the Make-Whole Premium to the Trustee for the ratable benefit of the Holders as herein described is a material inducement to Holders to purchase the Securities.

At any time after such a declaration of acceleration with respect to Securities has been made, but before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article, the Holders of a majority in aggregate principal amount of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

(1)          the Company has paid or deposited with the Trustee a sum sufficient to pay in U.S. dollars,

(A)         all overdue interest, if any, on all Outstanding Securities,

(B)         all unpaid principal of (and premium including the Make-Whole Premium, if any, on) any Outstanding Securities which has become due otherwise than by such declaration of acceleration, and interest, if any, on such unpaid principal (and premium including the Make-Whole Premium, if any) at the rate or rates prescribed therefor in such Securities,

(C)         to the extent that payment of such interest is lawful, interest on overdue interest, if any, at the rate or rates prescribed therefor in such Securities, and

(D)         all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and

(2)          all Events of Default with respect to Securities other than the non-payment of amounts of principal of (or premium including the Make-Whole Premium, if any, on) or interest

on Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 6.13.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Upon the Trustee providing any declaration of acceleration, or rescission and annulment thereof pursuant to this Section 6.02 with respect to Securities all or part of which is represented by a Global Security, a record date shall automatically and without any other action by any Person be set for the purpose of determining the Holders of Outstanding Securities entitled to join such declaration of acceleration, or rescission and annulment, as the case may be, which record date shall be the close of business on the date the Trustee shall have provided such declaration of acceleration, or rescission and annulment, as the case may be.  The Holders of Outstanding Securities on such record date (or their duly appointed agents), and only such Persons, shall be entitled to join in such declaration of acceleration, or rescission and annulment, as the case may be, whether or not such Holders remain Holders after such record date; provided that, unless such declaration of acceleration, or rescission and annulment, as the case may be, shall have become effective by virtue of the requisite percentage having been obtained prior to the day which is 90 days after such record date (or their duly appointed agents), such declaration of acceleration, or rescission and annulment, as the case may by, shall automatically and without any action by any Person be cancelled and of no further effect.  Nothing in this paragraph shall prevent a Holder (or duly appointed agent thereof) from giving, before or after the expiration of such 90-day period, a declaration of acceleration, or a rescission and annulment of any such declaration, contrary to or different from a declaration previously given by a Holder, or from giving, after the expiration of such period, a declaration identical to a declaration of acceleration, or rescission and annulment thereof, as the case may be, that has been cancelled pursuant to the proviso to the preceding sentence, in any of which events a new record date shall be established pursuant to the provisions of this Section 6.02.

SECTION 6.03.        Collection of Indebtedness and Suits for Enforcement by Trustee .  The Company covenants that if:

(1)          default is made in the payment of any installment of interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or

(2)          default is made in the payment of the principal of (or premium including the Make-Whole Premium, if any, on) any Security at the Maturity thereof and on any date required under Section 3.09, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium including the Make-Whole Premium, if any) and interest, if any, and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium including the Make-Whole Premium, if any) and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name, as Trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated.

If an Event of Default with respect to Securities occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 6.04.        Trustee May File Proofs of Claim .  In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium including the Make-Whole Premium, if any, or interest, if any) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(1)          to file and prove a claim for the whole amount of principal (and premium including the Make-Whole Premium, if any) and interest, if any, owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and

(2)          to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payment 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 counsel, and any other amounts due the Trustee under Section 7.06.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.05.        Trustee May Enforce Claims Without Possession of Securities .  All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

SECTION 6.06.        Application of Money Collected .  Any money collected by the Trustee or the Collateral Agent pursuant to this Article (including upon any realization of any Lien upon Collateral) shall, subject to the terms of the Security Documents, be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium including the Make-Whole Premium, if any) or interest, if any, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

THIRD: The balance, to the Person or Persons entitled thereto.

Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture and the other Note Documents; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

SECTION 6.14.        Undertaking for Costs .  All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, 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, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder or group of Holders holding in the aggregate more than 25% in aggregate principal amount of the Outstanding Securities, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium including the Make-Whole Premium, if any) or interest on any Security on or after the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the redemption date).

Once delivered to the Trustee, Appendix N may be received or rescinded only by a writing signed by an authorized representative of the Company. Such revisions or rescissions shall be effective only after actual receipt and following such period of time as may be necessary to afford the Trustee a reasonable opportunity to act on it. If a revised Appendix N or a rescissions of an existing Appendix N is delivered to the Trustee by an entity that is a successor-in-interest to the Company, such document shall be accompanied by additional documentation satisfactory to the Trustee showing that such entity has succeeded to the rights and responsibilities of the Company under this Indenture.

(e)          The Company understands the Trustee’s inability to receive or confirm funds transfer instructions pursuant to the security procedures selected by the Company may result in a delay in accomplishing such funds transfer, and agree that the Trustee shall not be liable for any loss caused by any such delay.

Guarantees

SECTION 11.01.      Guarantees .  Each Guarantor of Securities hereby unconditionally and irrevocably guarantees, jointly and severally, on a senior basis to each Holder and to the Trustee and its successors and assigns (a) the full and punctual payment of principal of and interest on the Securities when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Indenture with respect to the Securities and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture with respect to the Securities (all the foregoing, being hereinafter collectively called the “ Guaranteed Obligations ”).  Each Guarantor of Securities further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Guarantor and that such Guarantor will remain bound under this Article 11 notwithstanding any extension or renewal of any obligation.

Each Guarantor of Securities waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment.  Each Guarantor of Securities waives notice of any default under the Securities or the Guaranteed Obligations.  The obligations of each Guarantor hereunder of Securities shall not be affected by (1) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company

or any other Person (including any Guarantor) under this Indenture with respect to the Securities or any other agreement or otherwise; (2) any extension or renewal of any thereof; (3) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture with respect to the Securities or any other agreement; (4) the release of any security held by any Holder or the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (6) except as set forth in Section 11.06, any change in the ownership of such Guarantor.

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

Except as expressly set forth in Sections 9.01, 11.02 and 11.06, the obligations of each Guarantor of Securities 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 of Securities herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture with respect to the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity.

Each Guarantor of Securities further agrees that its Securities Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder of Securities or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company 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, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (A) the unpaid amount of such Guaranteed Obligations, (B) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and (C) all other monetary Guaranteed Obligations of the Company to the Holders and the Trustee.

Each Guarantor of Securities agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations hereby may be accelerated as provided in Article 6 for the purposes of such Guarantor’s Securities 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 11.01.

Each Guarantor of Securities also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 11.01.

SECTION 11.02.      Limitation on Liability .  Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Guarantor of Securities shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

SECTION 11.03.     Successors and Assigns .  This Article 11 shall be binding upon each Guarantor and its successors and assigns and shall enure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 11.04.      No Waiver .  Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 11 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege.  The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 11 at law, in equity, by statute or otherwise.

SECTION 11.05.      Modification .  No modification, amendment or waiver of any provision of this Article 11, 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 11.06.     Release of Certain Guarantors .  (a) A Guarantor will be automatically released from its obligations under this Article 11:

(1)          as provided for in Section 4.13(f);

(b)          At the request of the Company and upon delivery of an Officer’s Certificate and Opinion of Counsel, if required, the Trustee shall execute and deliver an appropriate instrument evidencing the release of a Guarantor pursuant to this Section 11.06.

SECTION 11.07.      Execution and Delivery .  (a) To evidence its Securities Guarantee set forth in Section 11.01, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by an officer, director, general manager or person holding an equivalent title.

(b)          Each Guarantor hereby agrees that its Securities Guarantee set forth in Section 11.01 shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Securities Guarantee on the Securities.

(c)          If the person whose signature is on this Indenture no longer holds that office at the time the Trustee authenticates any Security, the Securities Guarantees shall be valid nevertheless.

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 or unless a written notice of any event which is in fact such a Default is received by the Collateral Agent at the address specified in Section 14.01, and such notice references the Securities and this Indenture.  The Collateral Agent shall take such action with respect to such Default or Event of Default as may be requested by the Trustee in accordance with Article 6 or the Holders of a majority in aggregate principal amount of the Securities (subject to this Section 12.05).

The Collateral Agent shall have no obligation and makes no representation whatsoever to the Trustee or any of the Holders as to the existence, genuineness, value or protection of the Collateral or the sufficiency of any Security Documents, or that the Collateral is owned by any of the Collateral Grantors or is cared for, protected or insured or has been encumbered, or that the Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Collateral Grantor’s property constituting Collateral intended to be subject to the Lien and security interest of the Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Collateral Agent pursuant to this Indenture or any other Security Documents, it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Collateral Agent shall have no other duty or liability whatsoever to the Trustee or any Holder as to any of the foregoing.  The grant of permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act.  For the avoidance of doubt, nothing herein shall require the Collateral Agent to file financing statements or continuation statements, to record any documents or instruments in any public office at any time or be responsible for perfection or maintaining the perfection of the security interests purported to be created by the Security Documents and such responsibility shall be solely that of the Company.

Each of the Collateral Agent and the Trustee, each in its capacity as such, shall not be liable or responsible for the failure of the Company or any Collateral Grantor to maintain insurance on the Collateral, nor shall it be responsible for any loss due to the insufficiency of such insurance or by reason of the failure of any insurer to pay the full amount of any loss against which it may have insured to the Company or any

Collateral Grantor, the Trustee, the Collateral Agent or any other Person.  The provisions of Article 7, mutatis mutandis, shall apply to the Collateral Agent.

The Holders by acquiring the Securities are deemed to have authorized the Collateral Agent, to create parallel debt obligations of any relevant Note Party as will be described in any Dutch Security Document (the “ Parallel Debt ”), including that an amount paid by any relevant Note Party in respect of a Parallel Debt will discharge the liability of that Note Party under the corresponding Notes Obligations.

SECTION 12.06.      Replacement of Collateral Agent .  The Collateral Agent may resign at any time by so notifying the Company.  The Holders of a majority in principal amount of the Securities may remove Collateral Agent with respect to the Securities by so notifying with 31 days prior notice to the Collateral Agent and may appoint a successor Collateral Agent.  The Company shall remove Collateral Agent if:

(1)         the Collateral Agent is adjudged bankrupt or insolvent;

(2)         a receiver or other public officer takes charge of the Collateral Agent or its property; or

(3)         the Collateral Agent otherwise becomes incapable of acting.

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

A successor Collateral Agent shall deliver a written acceptance of its appointment to the retiring Collateral Agent and to the Company.  Thereupon the resignation or removal of the retiring Collateral Agent shall become effective, and the successor Collateral Agent shall have all the rights, powers and duties of the Collateral Agent under this Indenture.  The successor Collateral Agent shall mail a notice of its succession to Holders of the Securities.  The retiring Collateral Agent shall promptly transfer all property held by it as Collateral Agent to the successor Collateral Agent.

If a successor Collateral Agent does not take office within 30 days after the retiring Collateral Agent resigns or is removed, the retiring Collateral Agent (at the Company’s expense) or the Holders of 10% in principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Collateral Agent.

The parties hereto acknowledge and agree that, for purposes of a Dutch Security Document, any resignation or removal by the Collateral Agent is not effective with respect to its rights and obligations under the Parallel Debt until such rights and obligations have been assigned to and assumed by a successor Collateral Agent. The retiring Collateral Agent will reasonably cooperate in assigning its rights under the Parallel Debt to any such successor Collateral Agent and will reasonably cooperate in transferring all rights under any Dutch Security Document to such successor Collateral Agent.

SECTION 12.07.      Purchaser Protected .  No purchaser or grantee of any property or rights purporting to be released from the Liens in favor of the Collateral Agent shall be bound to ascertain the authority of the Collateral Agent or Trustee to execute the release or to inquire as to the existence of any conditions herein prescribed for the exercise of such authority so long as the conditions set forth in Section 12.02 have been satisfied.

SECTION 12.08.      Authorization of Receipt of Funds by the Trustee Under the Security Documents .  The Trustee is authorized to receive any funds for the benefit of Holders distributed under the Security Documents and to apply such funds as provided in Section 6.06.

SECTION 12.09.      Powers Exercisable by Receiver or Trustee .  In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 12 upon any Collateral Grantor, as applicable, with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of any Collateral Grantor, as applicable, or of any officer or officers thereof required by the provisions of this Article 12.

SECTION 12.10.      Compensation and Indemnification .  The Collateral Agent shall be entitled to the compensation and indemnification set forth in Section 7.06 (with the references to the Trustee therein being deemed to refer to and include the Collateral Agent).

SECTION 12.11.      Form of Security Documents and Opinions .  To the extent that any provision of this Indenture or any Security Document requires the execution or delivery by the Trustee or the Collateral Agent after the Issue Date of any Security Documents, agreements, certificates, opinions or other documents (including, without limitation, any such opinions or documents described in the definition of “Collateral and Guaranty Requirements”), in each case, in form and substance reasonably satisfactory to the Trustee or the Collateral Agent, or other similar discretionary approval, or in substantially in the same form as such Security Documents, agreements, certificates, opinions or other documents were delivered on the Issue Date or as attached hereto, the Holders, by acquiring the Securities, are deemed to have approved the form and substance of any such Security Documents, agreements, certificates, opinions or other documents in substantially the same form as those executed and delivered on the Issue Date, in each case, with such changes as may be appropriate to reflect the entity subject to or the subject of or the governing law of such Security Documents, agreements, certificates, opinions or other documents and the jurisdiction of organization of such entity and hereby authorize the Trustee and the Collateral Agent, as applicable, to execute such documents and accept such documents and opinions.  For the avoidance of doubt, this Section 12.11 shall not supersede any requirement contained herein regarding the delivery of an Officer’s Certificate or an Opinion of Counsel.

Article 13

Additional Amounts

SECTION 13.01.      Payment of Additional Amounts .

(a)          The Company shall pay any amounts due with respect to the Securities and the Guarantors will pay any amounts due with respect to the Securities Guarantees without deduction or withholding for any and all present and future withholding taxes, levies, imposts and charges (a “ withholding tax ”) imposed by or for the account of the Cayman Islands, Switzerland or any other jurisdiction in which either the Company or a Guarantor is a resident for tax purposes or any political subdivision or taxing authority of such jurisdiction (the “ Taxing Jurisdiction ”), unless such withholding or deduction is required by law.  If such deduction or withholding is at any time required, the Company or such Guarantor, as applicable, will, to the fullest extent allowed by law (subject to compliance by the holder of a Security with any relevant administrative requirements), pay additional amounts (the “ Additional Amounts ”) in respect of principal amount, redemption price and interest (if any), in accordance with the terms of the Securities and this Indenture, as may be necessary so that the net amounts paid to the holder or the Trustee after such deduction or withholding will equal the principal amount, redemption price and interest (if any), on the Securities.  However, neither the Company nor any Guarantor will pay any Additional Amounts in the following instances:

(1)          if any withholding would not be payable or due but for the fact that (i) the holder of a Security (or a fiduciary, settlor, beneficiary of, member or shareholder of, the holder, if the holder is an estate, trust, partnership or corporation), is a domiciliary, national or resident of, or engaging in business or maintaining a permanent establishment or being physically present in, the Taxing Jurisdiction or otherwise having some present or former connection with the Taxing Jurisdiction other than the holding or ownership of the Security or the collection of principal amount, redemption price, repurchase price and interest (if any), in accordance with the terms of the Securities and this Indenture, or the enforcement of the Security or (ii) where presentation is required, the Security was presented more than 30 days after the date such payment became due or was provided for, whichever is later;

(2)          if any withholding tax is attributable to any estate, inheritance, gift, sales, transfer, excise, personal property or similar tax, levy, impost or charge;

(3)          if any withholding tax is attributable to any tax, levy, impost or charge which is payable otherwise than by withholding from payment of principal amount, redemption price, repurchase price and interest (if any);

(4)          if any withholding tax would not have been imposed but for the failure to comply with certification, information, documentation or other reporting requirements concerning the nationality, residence, identity or connections with the relevant tax authority of the holder or beneficial owner of the Security, if this compliance is required by statute or by regulation as a precondition to relief or exemption from such withholding tax;

(5)          to the extent a holder of a Security is entitled to a refund or credit in such Taxing Jurisdiction of amounts required to be withheld by such Taxing Jurisdiction;

(6)          if any withholding is required to be made pursuant to laws enacted by Switzerland providing for the taxation of payments according to principles similar to those laid down in the draft legislation of the Swiss Federal Council of December 17, 2014, or otherwise changing the Swiss federal withholding tax system from an issuer-based system to a paying‑agent‑based system pursuant to which a person other than the issuer is required to withhold tax on any interest payments;

(7)          if any withholding tax or deduction is required to be made in respect of any tax, duty, assessment or other governmental charge imposed or withheld pursuant to Sections 1471 through 1474 of the Code, as of the date hereof (or any amended or successor version), current or future U.S. Treasury Regulations issued thereunder or any official interpretation thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code; or

(8)          any combination of the instances described in the preceding clauses.

(b)          With respect to clause (a)(5) above, in the absence of evidence satisfactory to the Company or the applicable Guarantor, it may conclusively presume that a holder of a Security is entitled to a refund or credit of all amounts required to be withheld.  The Company or the applicable Guarantor also will not pay any Additional Amounts to any holder who is a fiduciary or partnership or other than the sole beneficial owner of the Security to the extent that a beneficiary or settlor with respect to such fiduciary, or a member of such partnership or a beneficial owner thereof, would not have been entitled to the payment

of such Additional Amounts had such beneficiary, settlor, member or beneficial owner been the holder of the Security.

SECTION 13.02.      Swiss Minimum Interest .

(a)          When entering into this Indenture, the parties have assumed that the payments under the Indenture and the other Note Documents are not and will not become subject to any tax deduction on account of Swiss Withholding Tax.

(b)          Notwithstanding the paragraph above if a tax deduction on account of Swiss Withholding Tax should, at any time, be or become required by law in respect of any payment under the Indenture or any other Note Document and should it be unlawful for a Guarantor incorporated in Switzerland (each, a “ Swiss Guarantor ”) to comply with Section 13.01 for any reason (where this would otherwise be required by the terms of Section 13.01) then:

(1)          the applicable interest rate in relation to that payment shall be the interest rate which would have applied to that payment, as provided for in the applicable Security, divided by 1 minus the rate at which the relevant tax deduction is required to be made under Swiss domestic tax law and/or applicable double taxation treaties (where the rate at which the relevant tax deduction is required to be made is for this purpose expressed as a fraction of 1); and

(2)          such Swiss Guarantor shall:

(A)         pay the relevant interest at the adjusted rate in accordance with paragraph (1) above;

(B)         make a tax deduction on the interest so recalculated; and

(C)         all references to a rate of interest under the Note Documents shall be construed accordingly.
