The Notes are secured by a lien on the Deepwater Proteus and certain other assets related to the rig.  The Notes are fully and unconditionally guaranteed, jointly and severally, by the Guarantors on a senior basis (the “Guarantees”).  The Notes have not been registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), or under any state securities laws, and were offered only to qualified institutional buyers under Rule 144A under the Securities Act and outside the Unites States in compliance with Regulation S under the Securities Act.

The terms of the Notes are governed by the Indenture, which contains covenants that, among other things, (i) limit the activities of the Issuer, the collateral rig owner and the collateral rig operator, (ii) limit the ability of Transocean Inc. and its subsidiaries to incur liens and engage in certain sale and lease-back transactions, (iii) limit the ability of Transocean Inc.’s subsidiaries to incur indebtedness, and (iv) limit the ability of the Issuer and the Guarantors to consolidate, merge or enter into a scheme of arrangement qualifying as an amalgamation. The Indenture also contains customary events of default.  Indebtedness under the Notes may be accelerated in certain circumstances upon an event of default as set forth in the Indenture.

The description above does not purport to be complete and is qualified in its entirety by the Indenture filed herewith as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated by reference herein.

The Securities

SECTION 2.01.     Form and Dating.  Provisions relating to the Securities are set forth in Appendix A attached hereto (“Appendix A”) which is hereby incorporated in, and expressly made part of, this Indenture.  The Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit 1.1 and Exhibit 1.2 to Appendix A, in the case of the 144A Global Securities and Regulation S Global Securities, respectively, which are 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 Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company).  Each Security shall be dated the date of its authentication.  The terms of the Securities set forth in Appendix A are part of the terms of this Indenture.

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 $625,000,000.  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.

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

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.

SECTION 2.06.     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.  When a Security is presented to the Registrar or a co-registrar, if any, with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture (including Appendix A thereto) are met.  When Securities are presented to the Registrar or a co-registrar, if any, 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.

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

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

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

SECTION 2.10.     Cancellation.  The Company at any time may deliver Securities to the Trustee for cancellation.  The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment.  The Trustee and no one else shall cancel and dispose of (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancellation 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.

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.

(a)     Each Collateral Grantor party hereto agrees that it will, and Holdings agrees to cause each other Collateral Grantor to, at any time and from time to time, at the expense of such Collateral Grantor, promptly execute and deliver all further instruments and documents, and take all further action that may be reasonably necessary, to ensure that the Collateral and Guaranty Requirements are satisfied with respect to the Collateral Rig, including to perfect and protect any Lien granted or purported to be granted by the Security Documents, or to enable the Collateral Agent to exercise and enforce its rights and remedies under the Security Documents.  Without limiting the generality of the foregoing, the Collateral Rig Owner shall, and Holdings shall cause each Equity Pledgor and the Collateral Rig Operator to, execute, if required, and file, or cause to be filed, such financing or continuation statements under the Uniform Commercial Code (or any non-U.S. equivalent thereto), or amendments thereto, such amendments or supplements to the Collateral Rig Mortgage (including any amendments required to maintain Liens granted by the Collateral Rig Mortgage), and such other instruments or notices, to protect and preserve the Liens granted or purported to be granted by the Security Documents.

(b)     Subject to Section 12.05, each Collateral Grantor party hereto hereby authorizes the Collateral Agent to file one or more financing or continuation statements under the Uniform Commercial Code (or any non-U.S. equivalent thereto), and amendments thereto, relative to all or any part of the Collateral without the signature of such Collateral Grantor, as applicable, where permitted by law.  The Collateral Agent will promptly send the Company a copy of any financing or continuation statements which it may file without the signature of the relevant Collateral Grantor and the filing or recordation information with respect thereto.

(c)     In the event that the Collateral Rig is transferred to a Subsidiary of Holdings in accordance with Sections 4.13 and 4.29, as applicable, Holdings will cause the Subsidiary to which the Collateral Rig is transferred and any Subsidiary of Holdings which directly owns the Equity Interests of such Subsidiary, to the extent not already an Equity Pledgor, to satisfy the Collateral and Guaranty Requirements with respect to the Collateral Rig (including the requirement for the Collateral Rig Owner to execute a supplemental indenture substantially in the form of Appendix D hereto pursuant to which such Person will become a Guarantor) and the Equity Interests of the Collateral Rig Owner and take such other actions in connection therewith as would otherwise have been required to be taken pursuant to this Indenture

had such Subsidiary(ies) been the Collateral Rig Owner or an Equity Pledgor, as applicable, on the Issue Date (including the delivery of relevant opinions, officer certificates, resolutions and organizational documents) and deliver to the Collateral Agent an Officer’s Certificate confirming that the Collateral and Guaranty Requirements are satisfied and the Opinions of Counsel required as part of such Collateral and Guaranty Requirements.

(d)     In the event that the Drilling Contract is transferred to a Subsidiary of Holdings in accordance with Sections 4.13 and 4.29, as applicable, Holdings will cause the Subsidiary to which the Drilling Contract is transferred and any Subsidiary of Holdings which directly owns the Equity Interests of such Subsidiary (other than any Equity Interests of the Collateral Rig Operator owned by a Qualified Local Partner, if applicable at such time), to the extent not already an Equity Pledgor, to satisfy the Collateral and Guaranty Requirements with respect to the Drilling Contract and such Equity Interests of the Collateral Rig Operator and take such other actions in connection therewith as would otherwise have been required to be taken pursuant to this Indenture had such Subsidiary been the Collateral Rig Operator or an Equity Pledgor, as applicable, on the Issue Date (including the delivery of relevant opinions, officer certificates, resolutions and organizational documents) and deliver to the Collateral Agent an Officer’s Certificate confirming that the Collateral and Guaranty Requirements are satisfied and the Opinions of Counsel required as part of such Collateral and Guaranty Requirements.

(e)     Notwithstanding any provision contained herein or in any other Note Document, Collateral Rig Substitutions will be permitted so long as Holdings causes the Collateral Rig Owner to satisfy the Collateral and Guaranty Requirements with respect to the Collateral Rig contemporaneously with the consummation of such Collateral Rig Substitution and take such other actions in connection therewith as would otherwise have been required to be taken pursuant to this Indenture had the substituted Acceptable Rig been the Collateral Rig on the Issue Date (including the delivery of relevant opinions, officer certificates, resolutions and organizational documents).

(f)     Notwithstanding any provision contained herein or in any other Note Document, Drilling Contract Substitutions will be permitted so long as Holdings causes the Collateral Rig Operator to satisfy the Collateral and Guaranty Requirements with respect to the Drilling Contract contemporaneously with the consummation of such Drilling Contract Substitution and take such other actions in connection therewith as would otherwise have been required to be taken pursuant to this Indenture had the substituted Acceptable Drilling Contract been the Drilling Contract on the Issue Date (including the delivery of relevant opinions, officer certificates, resolutions and organizational documents).

SECTION 4.28.     Master Services Agreement.  Holdings shall cause the Collateral Rig Operator to continue to be a party to the Master Services Agreement and to have access to the Services (as defined therein) and personnel provided thereunder in order to comply with the performance standards under the Drilling Contract until the stated expiration date of the Drilling Contract regardless of whether the Collateral Rig Owner or the Collateral Rig Operator remains an Affiliate of Holdings.

(a)     such Subsidiary of Holdings has no Liens other than those permitted under the Indenture;

(b)     such Subsidiary of Holdings has no material contingent liabilities outside the ordinary course of business that would be reasonably likely to have a Material Adverse Effect on it or that would adversely affect the enforceability of any Lien for the benefit of the Holders or on any Securities Guarantee;

(c)     such Subsidiary of Holdings shall have provided to the Collateral Agent all relevant board resolutions and shareholder resolutions (if necessary) authorizing the consummation of the transactions contemplated by the Note Documents to which it will become a party and copies of its Organizational Documents;

(g)     such Subsidiary of Holdings shall have provided to the Collateral Agent all relevant legal opinions from counsel in relevant jurisdictions;

(h)     such Subsidiary of Holdings shall have executed and delivered to the Collateral Agent all Security Documents necessary to satisfy the Collateral and Guaranty Requirements, and the Collateral Agent shall have a first-priority perfected security interest in the Collateral purported to be covered by such agreements, subject to Permitted Collateral Liens, in each case, as certified by such Subsidiary in an Officer’s Certificate;

(i)     such Subsidiary of Holdings shall provide insurance materials that satisfy the Collateral and Guaranty Requirements and the requirements set forth in Section 4.08;

(j)     such Subsidiary of Holdings shall certify that the representations and warranties set forth on Annex I hereto applicable to it as the Collateral Rig Owner or Collateral Rig Operator, as applicable, are true and correct in all material respects; and

(k)     the Company shall deliver an Officers’ Certificate to the Trustee and the Collateral Agent certifying that all of the requirements of the immediately preceding clauses (a) through (j) (other than clause (d)) are satisfied and the Collateral Agent is authorized to enter into the applicable Security Documents in connection therewith. 

SECTION 4.30.     Post-Bankruptcy Restrictions.  Holdings shall, and Holdings shall cause its Subsidiaries to, not take or support any of the following actions after the occurrence of an Event of Default under Section 6.01(f) or (g): (a) reject the Drilling Contract or the Bareboat Charter; or (b) challenge any transfer made in connection with the Note Documents as a preference or fraudulent conveyance.

SECTION 4.31.     Waiver of Certain Covenants.  Holdings may and may cause any Subsidiary of Holdings to omit in any particular instance to comply with any term, provision or condition set forth in the Indenture or any applicable Note Document (other than any term, provision or condition the amendment or waiver of which would require the consent of each Holder of an Outstanding Security affected thereby,

pursuant to Section 10.02), if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities shall either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of Holdings and the Subsidiaries of Holdings and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to waive compliance with any covenant or condition hereunder.  If a record date is fixed, the Holders of such record date, or their duly appointed agents, and only such Persons shall be entitled to waive any such compliance, whether or not such Holders remain Holders after such record date, provided that unless the Holders of at least a majority in aggregate principal amount of the Outstanding Securities shall have waived such compliance prior to the date which is 90 days after such record date, any such waiver previously given shall automatically and without further action by any Holder be cancelled and of no further effect.

(1)     either (a) the Company shall be the continuing Person or (b) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or amalgamated, or to which such sale, lease, conveyance, transfer or other disposition is made (the “Successor”) expressly assumes by supplemental indenture the due and punctual payment of the principal of, premium (if any) and interest on and any Additional Amounts with respect to all the Securities and the performance of the Company’s covenants and obligations under this Indenture and the Securities;

effect as if such Successor had been named as the Company herein and the predecessor Company, in the case of a sale, conveyance, transfer or other disposition, shall be released from all obligations under this Indenture and the Securities, provided, that in the case of a lease of all or substantially all its assets, the predecessor Company will not be released from its obligations under this Indenture or the Securities.

Article 6

(e)     any Securities Guarantee ceases to be in full force and effect (other than in accordance with the terms of such Securities Guarantee or pursuant to the terms of this Indenture or other applicable Note Document) or any Guarantor denies or disaffirms its obligations under its Securities Guarantee;

(f)     the Company or any other Note Party pursuant to or within the meaning of any Bankruptcy Law:

(1)     commences a voluntary case,

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

(3)     consents to the appointment of a Bankruptcy Custodian of it or for all or substantially all of its property, or

(4)     makes a general assignment for the benefit of its creditors;

(g)     a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that remains unstayed and in effect for 90 days and that:

(1)     is for relief against the Company or any other Note Party as debtor in an involuntary case,

(2)     appoints a Bankruptcy Custodian of the Company or any other Note Party or a Bankruptcy Custodian for all or substantially all of the property of the Company, or any other Note Party or

(3)     orders the liquidation of the Company or any other Note Party;

(h)     except as permitted by the Note Documents, the Security Documents shall for any reason cease to create a valid and perfected first-priority Lien (subject to Permitted Collateral Liens) on any portion of the Collateral having a fair market value in excess of $25,000,000 (in each case, other than in accordance with the terms of this Indenture or the terms of the Security Documents); provided that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 45 days after any Officer of any Collateral Grantor becomes aware of such failure, which failure has not been cured during such time period, or (ii) any Collateral Grantor asserts in writing that any Lien created under the Security Documents is invalid or unenforceable; or

(i)     if Shell (or any other entity that is the counterparty under the Drilling Contract) is more than 120 days late with respect to the making of any payment under the Drilling Contract, the failure by the Collateral Rig Operator to actively pursue remedies under the Drilling Contract with respect to such nonpayment.

Upon the occurrence of an Event of Default pursuant to this Section 6.01 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 taken by any Person be set for the purpose of determining the Holders of Outstanding Securities entitled to join in any Notice of Default, which record date shall be the close of business on the day the Trustee shall have received such Notice of Default.  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 Notice of Default, whether or not such Holders remain Holders after such record date; provided that, unless such Notice of Default shall have become effective by virtue of Holders of the requisite principal amount of Outstanding Securities on such record date (or their duly appointed agents) having joined in such Notice of Default prior to the day which is 90 days after such record date, such Notice of Default 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 expiration of such 90-day period, a Notice of Default contrary to or different from a Notice of Default previously given by a Holder, or from giving, after the expiration of such period, a Notice of Default identical to a Notice of Default that has been cancelled pursuant to the proviso to the preceding sentence, in any of which events a record date in respect thereof shall be set pursuant to the provisions of this Section 6.01.

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, including 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 principal amount (or specified portion thereof) 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 December 1, 2020, 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.

Notwithstanding the preceding paragraph, in the event of a declaration of acceleration in respect of the Securities because of an Event of Default specified in Section 6.01(f) or 6.01(g) shall have occurred and be continuing, such declaration of acceleration shall be automatically annulled if the Indebtedness that is the subject of such Event of Default has been discharged or otherwise paid in full.

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:

FIRST: To the payment of all amounts due the Trustee or the Collateral Agent under Section 7.06;

SECOND: To the payment of the amounts then due and unpaid for principal of (and premium including the Make-Whole Premium, if any) and interest, if any, on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium including the Make-Whole Premium, if any) and interest, if any, respectively; and

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

SECTION 6.07.     Limitation on Suits.  No Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, the Securities, or the other Note Documents, or for the appointment of a receiver or trustee, or for any other remedy hereunder or thereunder, unless:

(1)     such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities;

(2)     the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(3)     such Holder or Holders have offered to the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request;

(4)     the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(5)     no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Outstanding Securities;

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing themselves of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such use by a Holder affects, disturbs or prejudices the rights of other Holders or obtains or seeks to obtain priority or preference over such other Holders or enforces any right under this Indenture).

SECTION 6.08.     Unconditional Contractual Right of Holders to Receive Principal, Premium and Interest.  Subject to the following sentence, notwithstanding any other provision in this Indenture, the Holder of any Security shall have the contractual right, which is absolute and unconditional, to receive payment, as provided herein (including, if applicable, Article 8) and in such Security of the principal of (and premium including the Make-Whole Premium, if any) and interest, if any, on such Security on the Stated Maturity or any Maturities (or, in the case of redemption, on the redemption date) and to institute suit for the enforcement of any such payment, and such contractual rights shall not be impaired without the

consent of such Holder.  Notwithstanding the foregoing, no amendment to, or deletion or waiver of any of the covenants described in Article 4 of this Indenture or in any other Note Document or any action taken by the Company or Guarantors not prohibited hereunder (other than with respect to actions set forth in the first paragraph of Section 10.02) shall be deemed to impair or affect any rights of any Holder to receive payment of principal of, and premium, interest and Additional Amounts, if any, on, the Notes.

SECTION 6.09.     Restoration of Rights and Remedies.  If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 6.10.     Rights and Remedies Cumulative.  Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 2.07, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.  The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 6.11.     Delay or Omission Not Waiver.  No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.  Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 6.12.     Control by Holders.  The Holders of not less than a majority in aggregate principal amount of the Outstanding Securities in respect of which an Event of Default has occurred shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Outstanding Securities, provided that in each case (1) such direction shall not be in conflict with any rule of law or with this Indenture, and (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

Upon receipt by the Trustee of any such direction with respect to Securities all or part of which is represented by a Global Security, a record date shall automatically and without any further action by any Person be set for the purpose of determining the Holders of Outstanding Securities entitled to join in such direction, which record date shall be the close of business on the day the Trustee shall have received such direction.  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 direction, whether or not such Holders remain Holders after such record date; provided that, unless such direction shall have become effective by virtue of Holders of the requisite principal amount of Outstanding Securities on such record date (or their duly appointed agents) having joined therein on or prior to the 90th day after such record date, such direction 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 a duly appointed agent of a Holder) from giving, before or after the expiration of such 90-day period, a direction contrary to or different from a direction previously given by a Holder, or from giving, after the expiration of such period, a direction identical to a direction that has been

cancelled pursuant to the proviso to the preceding sentence, in any of which events a new record date in respect thereof shall be set pursuant to the provisions of this Section 6.12.

SECTION 6.13.     Waiver of Past Defaults.  Subject to Section 6.02, the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities may on behalf of the Holders of all the Outstanding Securities waive any past Default or Event of Default hereunder, except a default

(1)     in the payment of the principal of (or premium including the Make-Whole Premium, if any) or interest on any Security or the payment of Additional Amounts, if any, or

(2)     in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of the Holder of each Outstanding Security affected.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to waive any past Default or Event of Default hereunder.  If a record date is fixed, the Holders on such record date (or their duly designated agents), and only such Persons, shall be entitled to waive any such default hereunder, whether or not such Holders remain Holders after such record date; provided, that unless such majority in principal amount shall have been obtained prior to the date which is 90 days after such record date, any such waiver previously given shall automatically and without further action by any Holder be cancelled and of no further effect.

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).

SECTION 6.15.     Waiver of Stay or Extension Laws.  The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted; provided that this Section shall not prohibit the Company from exercising any rights it may have under this Indenture to contest any actions taken by the Trustee pursuant to this Section.

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

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

SECTION 7.03.     Individual Rights of Trustee.  The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.  Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights.  However, the Trustee must comply with Section 7.09.

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

(1)     the Trustee fails to comply with Section 7.09;

(2)     the Trustee is adjudged bankrupt or insolvent;

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

(4)     the Trustee otherwise becomes incapable of acting.

If the Trustee 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 Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company.  Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture.  The successor Trustee shall mail a notice of its succession to Holders of the Securities.  The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.06.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.09, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.06 shall continue for the benefit of the retiring Trustee.

SECTION 7.08.     Successor Trustee by Merger.  If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

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

SECTION 7.09.     Corporate Trustee Required; Eligibility.  (a) There shall at all times be a Trustee hereunder which shall be:

(1)     a corporation organized and doing business under the laws of the United States, or of any state or territory thereof, or of the District of Columbia, authorized under such laws to exercise corporate trust powers, and subject to supervision or examination by federal or state authority, or

(2)     a corporation or other person organized and doing business under the laws of a foreign government permitted to act as a Trustee pursuant to a rule, regulation or other order of the Commission, authorized under such laws to exercise corporate trust powers, and subject to supervision or examination by authority of such foreign government or a political subdivision thereof substantially equivalent to supervision or examination applicable to United States institutional trustees.

(b)     The Trustee shall have at all times a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition.

SECTION 7.10.     Debt Service Reserve Account.

(a)     The Trustee agrees to open and maintain (other than with respect to funding) the Debt Service Reserve Account at all times. All amounts contained in the Debt Service Reserve Account are to be held in trust by the Trustee.

(b)     At any time that the amount on deposit in the Debt Service Reserve Account exceeds the Debt Service Reserve, the Company may withdraw the amount of such excess by executing and delivering a DSRA Withdrawal Certificate the form of which is attached hereto as Appendix L; provided that, the Company shall not make more than two such withdrawals in any calendar year.

(c)     Concurrently with the execution of this Indenture, the Company shall deliver to the Trustee Appendix N, which contains the authorized signer designations in Part A thereof.

(d)     The Trustee shall confirm each funds transfer instruction received in the name of the Company by means of the security procedure selected by the Company and communicated to the Trustee through a signed certificate in the form of Appendix N attached hereto, which upon receipt by the Trustee shall become a part of this Indenture. 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.

SECTION 8.06.     Reinstatement.  If the Trustee or any paying agent is unable to apply any money in accordance with Section 8.05 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture, the Note Documents and such Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.05; provided,  however, that if the Company makes any payment of principal of (or premium including the Make-Whole Premium, if any) or interest, if any, on any such Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or paying agent.

SECTION 10.03.     Execution of Supplemental Indentures.  The Trustee and the Collateral Agent (if applicable) shall sign any amendment or supplemental indenture authorized pursuant to this Article 10 if such amendment or supplemental indenture does not adversely affect the rights, duties or immunities of the Trustee or Collateral Agent, as applicable.  In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee and Collateral Agent (if applicable) shall be entitled to receive, and (subject to Section 7.01) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture and that such supplemental indenture is the legal, valid and binding obligation of Company and any Guarantors party thereto, enforceable against them in accordance with its terms, subject to customary exceptions.  The Trustee and

the Collateral Agent (if applicable) may, but shall not be obligated to, enter into any such amendment or supplemental indenture which affects the Trustee’s or Collateral Agent’s, as applicable, own rights, duties or immunities under this Indenture or otherwise.

SECTION 10.06.     Notice of Supplemental Indentures.  Promptly after the execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of Section 10.03, the Company shall give notice thereof to the Holders of each Outstanding Security affected, in the manner set forth in Section 14.01, setting forth in general terms the substance of such supplemental indenture.

Article 11

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)     upon a Fundamental Change of such Guarantor in accordance with Section 4.13;

(2)     upon defeasance or covenant defeasance of the Securities pursuant to Article 8 or if the Company’s obligations under this Indenture are satisfied and discharged pursuant to Article 9; or

(3)     in the case of the Collateral Rig Owner, upon the replacement of such Collateral Rig Owner in connection with a transfer of the Collateral Rig in accordance with Section 4.29 pursuant to which another wholly-owned Subsidiary of Holdings shall become the Collateral Rig Owner and a Guarantor hereunder.

(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.

(d)     The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Securities Guarantee set forth in this Indenture on behalf of the Guarantors.

Article 12

(b)     Holdings shall cause every Collateral Grantor to from time to time take the actions required by Section 4.27.

(b)     upon defeasance or covenant defeasance of the Securities pursuant to Article 8 or if the Company’s obligations under this Indenture are satisfied and discharged pursuant to Article 9;

SECTION 12.03.     Release Documentation.  Upon compliance with the conditions to release of all or any portion of the Collateral set forth in Section 12.02, the Collateral Agent and the Trustee shall forthwith take all necessary action (at the request of and the expense of the Company, accompanied by an Officers’ Certificate and Opinion of Counsel that the conditions precedent to such release have been satisfied) to release and re-convey to the applicable Collateral Grantor the applicable portion of the Collateral that is authorized to be released pursuant to Section 12.02, and shall deliver such Collateral  in its possession to the applicable Collateral Grantor, including, without limitation, executing and delivering releases and satisfactions wherever required. 

SECTION 12.04.     Possession and Use of Collateral; No Impairment of the Security Interests.

(a)     So long as no Event of Default has occurred and is continuing, and subject to the terms of this Indenture and the Security Documents, each Collateral Grantor will be entitled to freely operate the property and assets constituting the Collateral pledged by it and to receive, invest and dispose of all cash dividends, principal, interest and other payments made upon or with respect to the Collateral pledged by it and to exercise any voting and other consensual rights pertaining to the Collateral pledged by it.

(b)     No Collateral Grantor shall take any action, or knowingly omit to take any action, which action or omission would have the result of materially impairing the validity, perfection or priority of the security interests in the Collateral created by the Security Documents, (except as expressly set forth in this Indenture or the Security Documents, including any action that would result in a Permitted Collateral Lien).

(c)     No Collateral Grantor shall take any action or otherwise attempt to enforce any claim or maritime lien held by it against the Collateral Rig that has priority over any claim or Lien of the Collateral Agent in respect of such Collateral Rig, including any claims or Liens arising under the Collateral Rig Mortgage.

(d)     The Collateral Agent will distribute all funds received by it in accordance with the provisions of the Security Documents, and the Trustee will distribute all funds received by it from the Collateral Agent for the benefit of the Trustee and the Holders in accordance with the provisions of this Indenture.

SECTION 12.05.     Collateral Agent.  The Trustee and each of the Holders by acceptance of the Securities hereby authorize the appointment of the Collateral Agent as the Trustee’s and the Holders’ Collateral Agent under the Security Documents and in its capacity as mortgagee and security trustee pursuant to the Collateral Rig Mortgage, and the Trustee and each of the Holders by acceptance of the Securities hereby irrevocably authorize the Collateral Agent to enter into the Security Documents and to take such action on their behalf under the provisions of the Security Documents and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture and the Security Documents, together with such powers as are reasonably incidental thereto.  Notwithstanding any provision to the contrary contained elsewhere in this Indenture and 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 herein 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 fiduciary relationship with the Trustee, any Holder, the Company, any Collateral Grantor or any Guarantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture and the Security Documents or otherwise exist against the Collateral Agent.  Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture 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 Trustee is authorized and directed by the Holders and the Holders by acquiring the Securities are deemed to have authorized the Trustee, as applicable, to cause the Collateral Agent to enter into and perform its obligations under the Security Documents.  The Collateral Agent is authorized and directed by the Trustee and the Holders and the Holders by acquiring the Securities are deemed to have authorized the Collateral Agent, to (i) enter into the Security Documents to which it is a party, (ii) bind the Trustee and the Holders on the terms as set forth in such Security Documents and (iii) perform and observe its obligations and exercise its rights and powers under such Security Documents, including entering into

amendments, supplements and other modifications permitted by the terms of this Indenture or the Security Documents.  Each Holder, by its acceptance of a Security, is deemed to have consented and agreed to the terms of each Security Document, as originally in effect and as amended, restated, replaced, supplemented or modified from time to time in accordance with its terms or the terms of this Indenture.  Each of the Holders by acquiring the Securities is hereby deemed to have directed the Trustee to appoint the Collateral Agent as its mortgagee and security trustee to receive, hold, administer and enforce the Collateral Rig Mortgage covering the Collateral Rig, as contemplated under this Indenture.

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.

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.

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 or deduction is required to be made pursuant to any agreements between the European Community and other countries or territories providing for measures equivalent to those laid down in the Council Directive 2003/48/EC, including, but not limited to, the agreement between the European Union and Switzerland of October 26, 2004, or any law or other governmental regulation implementing or complying with, or introduced in order to conform to, such agreements;

(7)     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;

(8)     if any withholding tax or deduction is required to be made pursuant to an agreement between Switzerland and another country or countries on final withholding taxes levied by Swiss paying agents in respect of persons resident in the other country on income of such person on any Securities booked or deposited with a Swiss paying agent (Abgeltungssteuer), and such holder of a Security chooses not to provide the certification, documentation or other information that would eliminate such withholding or deduction;

(9)     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

(10)     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.
