Provisions relating to the Notes are set forth in the Rule 144A/Regulation S Appendix attached hereto (the “ Appendix ”), which is hereby incorporated in and expressly made part of this Indenture. The Notes and the Trustee’s certificate of authentication therefor shall be substantially in the form of Exhibit 1 to the Appendix, which is hereby incorporated in and expressly made a part of this Indenture. The Notes may have other notations, legends or endorsements required by law, stock exchange rule or usage. Each Note shall be dated the date of its authentication. The terms of the Notes set forth in the Appendix are part of the terms of this Indenture. The Notes shall be in minimum denominations of $50,000 and integral multiples of $1,000 in excess thereof.

The terms and provisions contained in the Appendix and the Notes shall constitute, and are hereby expressly made, a part of this Indenture and the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any such provision conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

At least one Officer of the Company shall sign the Notes on behalf of the Company by manual or facsimile signature.

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

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

On the Issue Date, the Trustee shall authenticate and deliver Notes in an aggregate principal amount of $750,000,000 and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Notes for original issue in an aggregate principal amount specified in an authentication order of the Company. Such order shall specify the aggregate principal amount of the Notes to be authenticated, the date on which the original issue of Notes is to be authenticated and to whom the Notes shall be registered and delivered and, in the case of an issuance of Additional Notes pursuant to Section 2.14 after the Issue Date, shall certify that such issuance is in compliance with Section 4.09 .

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the Notes. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes 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.

36

The Company shall at all times maintain an office or agency in the United States where Notes may be presented for registration of transfer or for exchange (the “ Registrar ”) and an office or agency in New York, New York where Notes may be presented for payment (the “ Paying Agent ”). The Registrar shall keep a register of the Notes and of their transfer and exchange (the “ Register ”). The Company may have one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar, and the term “Paying Agent” includes any additional paying agent.

The Company shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture, which shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee in writing of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such. Other than for purposes of effecting a redemption or an offer to purchase described in Sections 3.07 , 3.08 , 3.09 , 4.10 and 4.15 or in connection with Legal Defeasance, Covenant Defeasance or Discharge, the Company or any of its Subsidiaries may act as Paying Agent or Registrar.

The Company initially appoints the Trustee as Registrar and Paying Agent in connection with the Notes at the Corporate Trust Office of the Trustee.

Prior to 11:00 a.m. New York City time, on each date on which any principal, premium, if any, or interest on any Note is due and payable, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal, premium, if any, and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, or premium, if any, interest, if any, or Additional Amounts, if any, on, the Notes and shall notify the Trustee of any default by the Company in making any such payment. If the Company or any of its Subsidiaries acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund for the benefit of the Holders. The Company at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any Event of Default under Section 6.01(a) or (b) , upon written request to a Paying Agent, require such Paying Agent to forthwith pay to the Trustee all sums so held in trust by such Paying Agent and, in each case, to account for any funds disbursed by such Paying Agent. Upon complying with this Section, the Paying Agent (if other than the Company or any of its Subsidiaries) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy, reorganization or similar proceeding with respect to the Company, the Trustee shall serve as Paying Agent for the Notes.

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 Noteholders. If the Trustee is not the

37

Registrar, the Company shall furnish to the Trustee in writing, at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Noteholders.

The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note for registration of transfer and in compliance with the Appendix. When a Note is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture. When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. The Company may require payment of a sum sufficient to cover any taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section (other than any such transfer taxes, assessments or similar governmental charge payable upon exchange or transfer pursuant to Section 3.06 , 4.10 , 4.15 or 9.05 ).

If a mutilated Note is surrendered to the Registrar or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall, upon its receipt of an authentication order from the Company, authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Registrar or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Registrar, the Trustee and the Company to protect the Company, the Trustee, the Paying Agent and the Registrar from any loss which any of them may suffer if a Note is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Note.

Every replacement Note is an additional obligation of the Company.

The Notes outstanding at any time are all Notes 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. Except as set forth in Section 2.09 , a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

If the Paying Agent (other than the Company or a Subsidiary thereof) holds in trust, in accordance with this Indenture, by 11:00 a.m. New York City time, on a redemption date or other maturity date money sufficient to pay all principal, interest, premium, if any, and Additional Amounts, if any, payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Notes (or portions thereof) shall cease to be outstanding and interest on them shall cease to accrue.

38

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee actually knows are so owned will be so disregarded.

Until definitive Notes are ready for delivery, the Company may prepare and the Trustee shall, upon its receipt of an authentication order from the Company, authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes and deliver them in exchange for temporary Notes. Holders of temporary Notes shall be entitled to all of the benefits under this Indenture.

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

If the Company defaults in a payment of interest on the Notes, the Company shall pay defaulted interest at the rate specified in the second paragraph of Section 4.01 (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 Noteholders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date (which special record date shall not be less than 10 days prior to the related payment date) to the reasonable satisfaction of the Trustee and shall promptly mail to each Noteholder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

The Company in issuing the Notes may use “CUSIP” numbers and corresponding “ISINs” (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers and corresponding “ISINs” in notices of redemption as a convenience to Holders; provided , however ,

39

that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee of any changes in “CUSIP” or “ISIN” numbers.

The Company shall be entitled, subject to its compliance with Section 4.09 , to issue Additional Notes under this Indenture in an aggregate amount not exceeding the Additional Notes Amount, which Additional Notes shall have identical terms and conditions as the Initial Notes issued on the Issue Date, other than with respect to the date of issuance, issue price and the date from which interest will accrue. The Initial Notes issued on the Issue Date, and any Additional Notes, will be equally and ratably secured by the Liens granted to the Collateral Agent on the Collateral and shall be treated as a single class for all purposes under this Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase.

With respect to any Additional Notes, the Company shall set forth in an Officers’ Certificate, which shall be delivered to the Trustee, the following information:

(1) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture and the provision of Section 4.09 that the Company is relying on to issue such Additional Notes; and

REDEMPTION AND PREPAYMENT

If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 or is required to redeem Notes pursuant to Section 3.08 , it shall furnish to the Trustee, at least five Business Days (unless a shorter period shall be agreeable to the Trustee) before the date of giving notice of the redemption pursuant to Section 3.03 , an Officers’ Certificate setting forth (i) either the clause of Section 3.07 pursuant to which the redemption shall occur or that such redemption shall occur pursuant to Section 3.08 , (ii) the redemption date, (iii) the principal amount of Notes to be redeemed, (iv) the redemption price or the method by which it will be determined, and (v) whether the Company requests that the Trustee give notice of such redemption.

If less than all of the Notes are to be redeemed at any time, the Trustee will select the Notes to be redeemed on a pro rata basis, by lot to the extent practicable or, in the case of Global Notes, by such other method in accordance with the applicable procedures of the Depositary,

40

unless otherwise required by law or applicable stock exchange or Depositary requirements, from the outstanding Notes not previously called for redemption. In the event of partial redemption other than on a pro rata basis, the particular Notes to be redeemed shall be selected, not less than five Business Days (unless a shorter period shall be agreeable to the Trustee) prior to the giving of notice of the redemption pursuant to Section 3.03 , by the Trustee from the outstanding Notes not previously called for redemption.

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. No Notes of $50,000 or less can be redeemed in part. Notes and portions of Notes selected shall be in amounts of $50,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder shall be redeemed. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

Except as otherwise provided in Section 3.08 in relation to a mandatory redemption, at least 30 days but not more than 60 days before a redemption date (except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a Legal Defeasance, Covenant Defeasance or Discharge), the Company shall mail or cause to be mailed, by first class mail, or otherwise given in accordance with the procedures of the Depository, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address (with a copy to the Trustee). Except with respect to redemption pursuant to Section 3.08 , notices of redemption may be subject to one or more conditions specified in the notice of redemption.

The notice shall identify the Notes to be redeemed and shall state:

(a) the redemption date;

(b) the redemption price or, if the redemption price is not then determinable, the manner in which it is to be determined;

(c) if any Note is to be redeemed in part only, the portion of the principal amount of such Note that is to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in a principal amount equal to the unredeemed portion of the original Note will be issued in the name of the applicable Holder upon cancellation of the original Note;

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

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

(f) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption shall cease to accrue on and after the redemption date and the only remaining right of the Holders of such Notes is to receive payment of the redemption price upon surrender to the Paying Agent of the Notes redeemed;

41

(g) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed;

(h) the CUSIP (or ISIN) number, if any, and that no representation is made as to the correctness or accuracy of the CUSIP (or ISIN) number, if any, listed in such notice or printed on the Notes; and

(i) a description of any conditions to the Company’s obligations to complete the redemption.

If any of the Notes to be redeemed is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depository applicable to redemption.

At the Company’s request, the Trustee shall give the notice of optional redemption in the Company’s name and at its expense; provided , however , that the Company shall have delivered to the Trustee, as provided in Section 3.01 , an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the second preceding paragraph.

Once notice of redemption is mailed in accordance with Section 3.03 , Notes (or portions thereof) called for redemption become irrevocably due and payable on the applicable redemption date at the applicable redemption price, subject to the satisfaction of any conditions to the redemption specified in the notice of redemption. If mailed in the manner provided for in Section 3.03 , the notice of redemption shall be conclusively presumed to have been given whether or not a Holder receives such notice. Failure to give timely notice or any defect in the notice shall not affect the validity of the redemption.

Prior to 11:00 a.m., New York City time, on any redemption date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary thereof is acting as Paying Agent, segregate and hold in trust as provided in Section 2.04 ) money sufficient in same day funds to pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The Paying Agent shall promptly return to the Company any money deposited with the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of and accrued interest on all Notes to be redeemed.

If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption whether or not such Notes are presented for payment, and the only remaining right of the Holders of such Notes shall be to receive payment of the redemption price upon surrender to the Paying Agent of the Notes redeemed. If any Note called for redemption shall not be so paid

42

upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 .

Upon surrender of a Note that is redeemed in part, the Company shall issue in the name of the applicable Holder and the Trustee shall, upon its receipt of an authentication order from the Company, authenticate for such Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

(a) At any time prior to June 1, 2016, the Company may, at its option, redeem up to 35% of the aggregate principal amount of Notes (including any Additional Notes) issued under this Indenture, at one time or from time to time, at a redemption price equal to 105.375% of the principal amount thereof, plus accrued and unpaid interest and Additional Amounts, if any, thereon to the applicable redemption date (subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), in an amount not greater than the net cash proceeds received by the Company from one or more Equity Offerings; provided that:

(1) at least 65% of the aggregate principal amount of Notes (including any Additional Notes) issued under this Indenture (excluding any Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

(2) the redemption occurs within 120 days after the date of the closing of such Equity Offering.

(b) At any time prior to June 1, 2016, the Company may, at its option, redeem the Notes, in whole or in part, at one time or from time to time, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest and Additional Amounts, if any, to, the applicable redemption date, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date.

(c) At any time prior to June 1, 2016, not more than once in any 12-month period, the Company may redeem up to $75.0 million in principal amount of the Notes at a redemption price equal to 103% of the aggregate principal amount thereof, plus accrued and unpaid interest and Additional Amounts, if any, to the redemption date, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date.

(d) On or after June 1, 2016, the Company may, at its option, redeem the Notes, in whole or in part, at one time or from time to time, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid

43

interest and Additional Amounts, if any, on the Notes redeemed, to the applicable redemption date, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date, if redeemed during the twelve-month period beginning on June 1 of the years indicated below:

(e) The Company may redeem the Notes, at its option, at any time in whole but not in part, at a redemption price equal to 100% of the outstanding principal amount of Notes, plus accrued and unpaid interest (if any) to the applicable redemption date, plus all Additional Amounts, if any, then due and which will become due as a result of the redemption or otherwise (subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), in the event that the Company determines in good faith that the Company or any Guarantor has become or would become obligated to pay, on the next date on which any amount would be payable with respect to the Notes or the Subsidiary Guarantees, Additional Amounts, and such obligation cannot be avoided by taking reasonable measures available to the Company or the relevant Guarantor, as applicable (including making payment through a Paying Agent located in another jurisdiction), as a result of:

(1) a change in or an amendment to the laws or treaties (including any regulations or rulings promulgated thereunder) of any Specified Tax Jurisdiction affecting taxation, which change or amendment is announced or becomes effective on or after the Issue Date; or

(2) any change in or amendment to any official position of a taxing authority in any Specified Tax Jurisdiction regarding the application, administration or interpretation of such laws, treaties, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction), which change or amendment is announced or becomes effective on or after the Issue Date;

provided , however , that in the case of Additional Amounts required to be paid as a result of the Company or relevant Guarantor conducting business other than in the place of its incorporation or organization, such amendment or change must be announced or become effective on or after the date in which it begins to conduct business giving rise to the relevant withholding or deduction.

Notwithstanding the foregoing, no such notice of redemption may be given earlier than 60 days prior to the earliest date on which the Company or the relevant Guarantor, as applicable, would be obligated to pay Additional Amounts if a payment in respect of the Notes or the Subsidiary Guarantees were then due, and at the time such notice is given, the obligation to pay Additional Amounts must remain in effect. Before the

44

Company mails or delivers notice of redemption of the Notes as described above, the Company will deliver to the Trustee and Paying Agent (a) an Officers’ Certificate stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Company to so redeem have occurred and (b) an opinion of independent legal counsel of recognized standing that the Company or any Guarantor has or will become obligated to pay Additional Amounts as a result of the circumstances referred to in clause (1) or (2) of the preceding paragraph.

The Trustee and Paying Agent will be entitled to conclusively rely upon the Officers’ Certificate and opinion of counsel as sufficient evidence of the satisfaction of the conditions precedent described above, in which case they will be conclusive and binding on the holders.

For the avoidance of doubt, the implementation of European Council Directive 2003/48/EC or any other directive implementing the conclusions of the ECOFIN Council meeting of 26 and 27 November 2000 on the taxation of savings income or any law implementing or complying with or introduced in order to conform to, such directive will not be a change or amendment for such purposes.

(f) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Section 3.01 through Section 3.05 .

(a) The Company shall deposit or cause to be deposited all Event of Loss Proceeds in a deposit account controlled by the Collateral Agent within three Business Days of the receipt thereof, with such Event of Loss Proceeds being held as Collateral therein and subject to a Lien under the Collateral Agreements pending application thereof as set forth in clause (b) below. The Company may withdraw such Event of Loss Proceeds from such deposit account to redeem or repay Pari Passu Obligations in compliance with clause (b) below.

(b) Upon the occurrence or happening of any Event of Loss and the receipt of Event of Loss Proceeds in respect thereof, the Company shall be required (subject to the payment priority in favor of the holders of Revolving Credit Agreement Obligations set forth in the Intercreditor Agreement and the Revolving Credit Agreement) to redeem Notes and other Pari Passu Obligations containing provisions similar to those set forth in the Indenture with respect to a redemption or repayment upon an Event of Loss equal in aggregate principal amount to the Event of Loss Proceeds received in respect of such Event of Loss (rounded to the nearest $1,000), upon notice as provided in this Section 3.08 , at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Amounts, if any, on the Notes redeemed to the applicable redemption date, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date. The Company shall deliver the notice of such mandatory redemption to the Holders within 30 days after the receipt of any Event of Loss Proceeds, and such notice shall state, in addition to the

45

matters specified in clauses (a) through (h) of Section 3.03 , that the Notes are being redeemed with Event of Loss Proceeds. If the aggregate principal amount of Notes and other Pari Passu Obligations exceeds the amount of the Event of Loss Proceeds, the Collateral Agent shall select Notes and such other Pari Passu Obligations to be redeemed or repaid on a pro rata basis; provided that any such repayment or redemption of other Pari Passu Obligations may be made at such time as is specified in the relevant Pari Passu Document and need not be concurrent with the redemption of the Notes.

(c) Any redemption pursuant to this Section 3.08 shall be made pursuant to the provisions of Sections 3.01 through 3.06 , except to the extent otherwise specified herein.

(a) In the event that, pursuant to Section 4.10 , the Company shall be required to commence an Asset Sale Offer, it shall follow the additional procedures specified below.

(b) Each Asset Sale Offer shall remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “ Asset Sale Offer Period ”).

The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders.

(ii) the Offer Amount, the purchase price and the Asset Sale Offer Settlement Date;

(iii) that any Note not tendered or accepted for payment shall continue to accrue interest;

(vii) that, if the aggregate principal amount of Notes surrendered by Holders or other Indebtedness of the Company or the applicable Restricted Subsidiary surrendered by holders thereof, collectively, exceeds the Asset Sale Offer Amount, the Trustee shall select the Notes to be purchased from the amount allocated therefor on a pro rata basis, by lot to the extent practicable or, in the case of Global Notes, by such other method in accordance with the applicable procedures of the Depositary (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of $50,000 and integral multiples of $1,000 in excess thereof will be outstanding after such purchase) and, if applicable, the Company will select such other Indebtedness for purchase or redemption based on amounts tendered or required to be prepaid; and

(viii) that Holders whose Notes were purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $50,000 in principal amount or an integral multiple of $1,000 in excess thereof.

Prior to 11:00 a.m., New York City time, on the Asset Sale Offer Settlement Date, the Company, the Depositary or the Paying Agent, as the case may be, shall mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company shall promptly issue a new Note, and the Trustee shall, upon its receipt of an authentication order from the Company, authenticate and mail or deliver (or cause to be transferred by book-entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered.

The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided , however , that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in New York, New York for such purposes.

All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports.

(4) the payment of any dividend (or, in the case of any partnership or limited liability company, any similar distribution) by a Restricted Subsidiary that is not a wholly owned Subsidiary of the Company to the holders of its Equity Interests on a pro rata basis or basis more favorable to the Company or its Restricted Subsidiaries;

(5) so long as no Event of Default has occurred and is continuing, the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any current or former officer, director or employee of the Company or any of its Restricted Subsidiaries pursuant to any equity subscription agreement, employee stock ownership plan or similar trust, shareholders’ agreement or similar agreement; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $5.0 million in any calendar year (with any portion of such $5.0 million amount that is unused in any calendar year to be carried forward to successive calendar years and added to such amount);

(6) the purchase, redemption or other acquisition or retirement for value of Equity Interests deemed to occur upon the exercise or conversion of stock options, warrants, rights to acquire Equity Interests or other convertible securities, to the extent

For purposes of determining compliance with this Section 4.07 , in the event that a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in Section 4.07(a) or the preceding clauses (1) through (10) of this Section 4.07(b) or as a Permitted Investment, the Company will be permitted to divide or classify (or later divide, classify or reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this Section 4.07 .

54

(a) The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, create or permit to become effective any consensual encumbrance or restriction on the ability of any of the Restricted Subsidiaries to:

(1) pay dividends or make any other distributions on its Capital Stock to the Company or any of the Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any Indebtedness owed to the Company or any of the Restricted Subsidiaries; provided that the priority that any series of preferred stock of a Restricted Subsidiary has in receiving dividends or liquidating distributions before dividends or liquidating distributions are paid in respect of common stock of such Restricted Subsidiary shall not constitute a restriction on the ability to make dividends or distributions on Capital Stock for purposes of this Section 4.08 ;

(2) make loans or advances to the Company or any of the Restricted Subsidiaries; or

(3) sell, lease or transfer any of its properties or assets to the Company or any of the Restricted Subsidiaries

(all such actions set forth in these clauses (1) through (3) above being collectively referred to as “ Intercompany Transfers ”).

(b) The restrictions in Section 4.08(a) will not apply to encumbrances or restrictions on the ability of any of the Restricted Subsidiaries to make Intercompany Transfers existing under or by reason of:

(1) agreements governing Indebtedness as in effect on the Issue Date, including under the Revolving Credit Agreement, the Term Loan Agreement, the Senior Secured Credit Facility Agreement and the Existing PDV Notes Indenture, in each case as in effect on the Issue Date;

(2) restrictions contained in, or in respect of, Hedging Obligations permitted to be Incurred by this Indenture;

(5) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of the Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was Incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be Incurred;

55

(6) customary non-assignment provisions in contracts and licenses entered into in the ordinary course of business;

(7) purchase money obligations for property acquired in the ordinary course of business, mortgage financings and Capital Lease Obligations that impose restrictions on the property purchased or mortgaged or leased of the nature described in clause (3) of Section 4.08(a) ;

(8) any agreement for the sale or other disposition of the Capital Stock or all or substantially all of the assets of any Restricted Subsidiary that restricts distributions by that Restricted Subsidiary pending the sale or other disposition;

(12) any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (1), (3), (5) or (7) of this Section 4.08(b) ; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of the Company, not materially more restrictive with respect to such encumbrance and other restrictions taken as a whole than those prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing;

(13) encumbrances or restrictions of the nature described in clause (3) of Section 4.08(a) with respect to property under a charter, lease or other agreement that has been entered into in the ordinary course for the employment, charter or other hire of such property; and

(14) instruments governing Indebtedness that is permitted to be Incurred subsequent to the Issue Date pursuant to Section 4.09 ; provided that, at the time such Indebtedness is Incurred, either (a) such encumbrance or restriction is customary for financings of the same type, and such restrictions would not reasonably be expected to materially impair the Company’s ability to make scheduled payments of interest and principal on the Notes when due or any Guarantor’s ability to make payment under its Subsidiary Guarantee, as determined in good faith by the Board of Directors of the

56

Company or a Financial Officer of the Company or (b) restrictions therein are not materially more restrictive, taken as a whole, than those contained in (i) this Indenture, the Notes and the Subsidiary Guarantees or (ii) the Revolving Credit Agreement, the Term Loan Agreement, the Senior Secured Credit Facility Agreement or the Existing PDV Notes Indenture as in effect on the Issue Date, as determined in good faith by the Board of Directors or a Financial Officer of the Company.

(b) The provisions of Section 4.09(a) will not prohibit the Incurrence of any of the following items of Indebtedness (collectively, “ Permitted Debt ”):

(1) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness under one or more Credit Facilities in a maximum aggregate principal amount incurred under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company or such Restricted Subsidiary thereunder) not to exceed $150.0 million at any one time outstanding;

(2) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness under one or more Credit Facilities in a maximum aggregate principal amount incurred under this clause (2) at any one time outstanding (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company or such Restricted Subsidiary thereunder), not to exceed an amount equal to the sum of (i) for each Vessel for which the Company or a Restricted Subsidiary has entered into a contract for the construction or acquisition of such Vessel but which has not yet been delivered or acquired, the greater of (x) $500.0 million and (y) 75% of the Vessel Value for such Vessel at the time any such Indebtedness is Incurred plus (ii) for each other Vessel owned by the Company or a Restricted Subsidiary, the greater of (x) $425.0 million and (y) 70% of the Appraised Value for such Vessel at the time any such Indebtedness is Incurred;

57

(3) the Incurrence by (i) the Company and any Guarantor of Indebtedness represented by the Notes (including Additional Notes) and the related Subsidiary Guarantees and (ii) the Company or any Restricted Subsidiary of Existing Indebtedness;

(4) the Incurrence by the Company or any Restricted Subsidiary of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge, in whole or in part, any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be Incurred under the first paragraph of this covenant or clause (3) of this paragraph or this clause (4);

(5) the Incurrence by Company or any Restricted Subsidiary of intercompany Indebtedness between or among Company and any of the Restricted Subsidiaries; provided , however , that:

(A) if the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, in the case of the Company, or the applicable Subsidiary Guarantees, in the case of a Guarantor; and

(B) upon any (i) subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary, or (ii) sale or other transfer of any such Indebtedness to a Person that is not the Company or a Restricted Subsidiary, the exception provided by this clause (5) shall no longer be applicable to such Indebtedness and such Indebtedness will be deemed to have been Incurred at the time of any such issuance, sale or transfer;

(6) the Incurrence by the Company or any Restricted Subsidiary of Hedging Obligations in the ordinary course of business and not for speculative purposes;

(7) the guarantee by the Company or any Restricted Subsidiary of Indebtedness of the Company or a Restricted Subsidiary that was permitted to be Incurred by another provision of this covenant; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes or a Subsidiary Guarantee, then the guarantee shall be subordinated or pari passu , as applicable, to the same extent as the Indebtedness guaranteed;

(8) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness in respect of workers’ compensation claims, self-insurance obligations, and performance, customs, importation and surety bonds or other Indebtedness of a like nature, in each case in the ordinary course of business;

(9) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days;

58

(10) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness arising from agreements providing for indemnification, earn-outs, adjustment of purchase price or similar obligations, or guarantees or letters of credit, surety bonds or performance bonds securing any obligations of the Company or any Restricted Subsidiary pursuant to such agreements, in each case, Incurred in connection with the acquisition or disposition of any business, assets or the Capital Stock of a Subsidiary, other than guarantees of Indebtedness Incurred by any Person acquiring all or any portion of such business, assets or the Capital Stock of a Subsidiary for the purpose of financing such acquisition; provided, however , that, in the case of a disposition, the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds (including non-cash proceeds (the Fair Market Value of such non-cash proceeds being measured at the time received and without giving effect to any subsequent changes in value)) actually received by the Company and the Restricted Subsidiaries in connection with such disposition; and

(11) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness not otherwise permitted pursuant to clauses (1) through (10) above that, together with any other Indebtedness Incurred pursuant to this clause (11) then outstanding, has an aggregate principal amount or accreted value, as applicable, not to exceed the greater of (x) $100.0 million and (y) 2.5% of Consolidated Net Tangible Assets at such time.

For purposes of determining compliance with this Section 4.09 , in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (11) above, or is entitled to be Incurred pursuant to Section 4.09(a) , the Company or the applicable Restricted Subsidiary will be permitted to classify such item of Indebtedness (or any portion thereof) on the date of its Incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09 . The accrual of interest or Preferred Stock dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of Preferred Stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Preferred Stock or Disqualified Stock in the form of additional shares of the same class of Preferred Stock or Disqualified Stock will not be deemed to be an Incurrence of Indebtedness or an issuance of Preferred Stock or Disqualified Stock for purposes of this covenant; provided , in each such case, that the amount of any such accrual, accretion or payment is included in Consolidated Interest Expense of the Company as accrued. Further, the reclassification of any lease or other liability of the Company or any Restricted Subsidiary as Indebtedness due to a change of accounting principles after the Issue Date will not be deemed an incurrence of Indebtedness for purposes of this Section 4.09 .

The amount of any Indebtedness outstanding as of any date will be:

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

59

(2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and

(3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

(4) in the case of Hedging Obligations, the termination value of the agreement or arrangement giving rise to such Hedging Obligations that would be payable by the specified Person at such date.

For purposes of determining compliance with any dollar-denominated restriction on the Incurrence of Indebtedness, the Dollar Equivalent of the principal amount of Indebtedness denominated in another currency will be utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the case of term Indebtedness, or first committed, in the case of Indebtedness Incurred under a revolving credit facility; provided that (1) if such Indebtedness is Incurred to refinance other Indebtedness denominated in a currency other than dollars, and such refinancing would cause the applicable dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such dollar-denominated restriction will be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced and (2) the Dollar Equivalent of the principal amount of any such Indebtedness outstanding on the Issue Date will be calculated based on the relevant currency exchange rate in effect on the Issue Date.

Notwithstanding any other provision of this Section 4.09 , the maximum amount of Indebtedness that the Company or the applicable Restricted Subsidiary may Incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.

(a) The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, consummate any Asset Sale unless:

(1) the Company or the Restricted Subsidiary, as the case may be, receives consideration at the time of consummation of such Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received in such Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents; provided , however , to the extent that any disposition in such Asset Sale was of Collateral, the non-cash consideration received is pledged as Collateral under the Collateral Agreements within 20 Relevant Business Days, in accordance with the requirements set forth in this Indenture;

60

provided, that the foregoing requirements shall not apply with respect to any Involuntary Transfer.

(b) For purposes of Section 4.10(a) , each of the following will be deemed to be cash:

(1) any Indebtedness or other liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed, repaid or retired by the transferee of any such assets so long as the Company or such Restricted Subsidiary is released from further liability;

(2) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are, within 180 days after receipt thereof, converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents, to the extent of the cash or Cash Equivalents received in that conversion; and

(3) any stock or assets of the kind referred to in clauses (2) or (4) of Section 4.10(c) .

(c) Within 365 days after the receipt of any Net Proceeds from an Asset Sale (including, without limitation, an Involuntary Transfer), the Company or the applicable Restricted Subsidiary, as the case may be, may apply such Net Proceeds at its option to any combination of the following:

(1) to purchase, repay or prepay Pari Passu Obligations or other secured Indebtedness of the Company or any Guarantor or, in the case of an Asset Sale other than of Collateral, any Indebtedness (other than Indebtedness that is subordinated in right of payment to the Notes or the Subsidiary Guarantees, whether or not secured (including, without limitation, redemptions or other purchases of Notes)) of the Company or any Restricted Subsidiary (and, to the extent required pursuant to the terms of the Revolving Credit Agreement (as in effect on the Issue Date) in the case of revolving obligations, to correspondingly reduce commitments with respect thereto);

(2) to acquire all or substantially all of the assets of, or any Capital Stock of, any Person primarily engaged in a Permitted Business, if, in the case of any such acquisition of Capital Stock, such Person is or becomes a Restricted Subsidiary after giving effect to such acquisition;

(3) to make a capital expenditure for the Company or any of its Restricted Subsidiaries; or

(4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business (including, without limitation,

61

Vessels, related assets and any related Ready for Sea Costs) for the Company or any of the Restricted Subsidiaries or make any deposit, installment or progress payment in respect of such assets or payment of any related Ready for Sea Costs,

provided that (x) a binding commitment made within the 365-day period described above by the Company or the applicable Restricted Subsidiary to apply Net Proceeds from an Asset Sale in accordance with clauses (2), (3) and/or (4) above shall satisfy the requirements of such clauses with respect to such Net Proceeds, so long as (i) with respect to any binding commitment to purchase, acquire or construct an Additional Vessel with such Net Proceeds, such Net Proceeds are actually so applied within the later of 365 days from the receipt thereof from such Asset Sale and 365 days from the date any such binding commitment is made, and (ii) with respect to any other binding commitment to apply Net Proceeds pursuant to such clauses, such Net Proceeds are actually so applied within the later of 365 days from the receipt thereof from such Asset Sale and 180 days from the date any such binding commitment is made, and (y) if all or any portion of the assets sold or transferred in such Asset Sale constituted Collateral, in the case of any application of Net Proceeds pursuant to clauses (2) or (4) above, the Company shall, or shall cause the applicable Restricted Subsidiary to, pledge any assets (including, without limitation, any acquired Capital Stock) acquired with such Net Proceeds to secure the Pari Passu Obligations on a first-priority secured basis (subject to the payment priority in favor of the holders of Revolving Credit Agreement Obligations set forth in the Intercreditor Agreement and subject to Permitted Collateral Liens) pursuant to the Collateral Agreements in accordance with this Indenture.

(d) Pending the final application of any Net Proceeds, the Company or the applicable Restricted Subsidiary may apply the Net Proceeds to temporarily reduce outstanding revolving credit Indebtedness of the Company or any of the Restricted Subsidiaries, respectively, or invest the Net Proceeds in cash and Cash Equivalents.

(e) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.10(c) will constitute “ Excess Proceeds .” When the aggregate amount of Excess Proceeds exceeds $25.0 million, Company will, within 10 Business Days thereof, make an offer (an “ Asset Sale Offer ”) to all Holders in accordance with Section 3.09 and the Company will, or will cause the applicable Restricted Subsidiary to, make an Asset Sale Offer to all holders of unsubordinated Indebtedness of the Company or such Restricted Subsidiary containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem such Indebtedness with the proceeds of sales of assets to purchase or redeem the maximum principal amount of Notes and such unsubordinated Indebtedness that may be purchased or redeemed out of the Excess Proceeds; provided , that to the extent such Excess Proceeds were received in respect of the sale or transfer of assets that constituted Collateral, an Asset Sale Offer will be made solely to holders of Pari Passu Obligations. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest and Additional Amounts, if any, to the date of purchase, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company and the Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes or other Indebtedness tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select

62

the Notes for purchase on a pro rata basis, by lot to the extent practicable or by such other method in accordance with the applicable procedures of the Depositary (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of $50,000 and integral multiples of $1,000 in excess thereof will be outstanding after such purchase) and, if applicable, the Company will select such other Indebtedness for purchase or redemption based on amounts tendered or required to be prepaid. For the purposes of calculating the principal amount of any such Indebtedness not denominated in U.S. dollars, such Indebtedness shall be calculated by converting any such principal amounts into their Dollar Equivalent determined as of the Business Day immediately prior to the date on which the Asset Sale Offer is announced. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(f) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those requirements, laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.10 by virtue of such compliance.

(a) The Company will not, and will not permit any of the Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company and any Restricted Subsidiary (each, an “ Affiliate Transaction ”) involving, with respect to any such transaction or series of related transactions, payments or consideration in excess of $1.0 million, unless:

(1) the Affiliate Transaction is on terms that are either (a) no less favorable to the Company or the relevant Restricted Subsidiary than those that could have been obtained in a comparable arm’s-length transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of the Company and any Restricted Subsidiary or (b) if in the good faith judgment of the Company’s Board of Directors, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view; and

(2) the Company delivers to the Trustee:

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 4.11 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company; and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50.0 million, an opinion issued to the Board of Directors of the Company by an accounting, appraisal or investment banking firm of international standing or generally recognized in the shipping or offshore drilling industries as qualified to perform the tasks for which such firm has been engaged as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction from a financial point of view or that the terms of such Affiliate Transaction are no less favorable to the Company or the relevant Restricted Subsidiary than those that could have been obtained in a comparable arm’s-length transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of the Company and any Restricted Subsidiary.

63

For the avoidance of doubt, with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration of $25.0 million or less, the determination that such Affiliate Transaction or series of Affiliate Transactions complies with this covenant may be made by a Financial Officer of the Company.

(b) The following items will not be deemed to be Affiliate Transactions, as applicable, and, therefore, will not be subject to the provisions of Section 4.11(a) :

(1) any employment agreement, employee benefit plan, compensation plan or arrangement, officer or director indemnification agreement or any similar arrangement entered into by the Company or any of its Subsidiaries in the ordinary course of business and payments pursuant thereto;

(2) payment of reasonable directors’ fees to directors of the Company or any Restricted Subsidiary;

(3) transactions solely between or among the Company and/or any of its Restricted Subsidiaries;

(4) the issuance or sale of Equity Interests (other than Disqualified Stock) of the Company to, or receipt of capital contributions from, Affiliates of the Company;

(5) loans or advances to employees of the Company or any Restricted Subsidiary in the ordinary course of business not to exceed $7.5 million in the aggregate at any one time outstanding;

(6) transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

(7) Permitted Investments and Restricted Payments that do not violate the provisions of Section 4.07 ;

64

(8) transactions between the Company or any of its Restricted Subsidiaries and any Person that would not otherwise constitute an Affiliate Transaction except for the fact that one director of such other Person is also a director of the Company or such Restricted Subsidiary, as applicable; provided that such director abstains from voting as a director of the Company or such Restricted Subsidiary, as applicable, on any matter involving such other Person; and

(9) any agreement as in effect on the Issue Date or any amendments, renewals or extensions of any such agreement (so long as such amendments, renewals or extensions are not less favorable to the Holders).

The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist (i) any Lien of any kind on any Collateral, except pursuant to a Collateral Agreement or the Intercreditor Agreement and except for Permitted Collateral Liens, or (ii) any Lien of any kind securing Indebtedness on any of its property or assets that are not Collateral, except for Permitted Liens.

If, after the Issue Date, (a) the Company acquires or creates any Subsidiary that holds any Collateral Vessel or is an Internal Charterer or is otherwise a party to a Drilling Contract with respect to a Collateral Vessel (other than a Local Content Subsidiary), (b) any existing Subsidiary of the Company that is not already a Guarantor holds any Collateral Vessel or becomes party to a Drilling Contract with respect to a Collateral Vessel (other than a Local Content Subsidiary), (c) any Collateral Vessel-Owning Subsidiary acquires or creates any Material Subsidiary or any Subsidiary of any Collateral Vessel-Owning Subsidiary that was not a Material Subsidiary subsequently becomes a Material Subsidiary (in each case, other than an Unrestricted Subsidiary or any such Subsidiary by which a guarantee would be prohibited by applicable law, for so long as such prohibitions are in effect) or (d) any Subsidiary of the Company that is not already a Guarantor guarantees the Revolving Credit Agreement Obligations or the Term Loan Obligations, then the Company will (1) cause such Subsidiary to, within 20 Relevant Business Days of such event, (A) execute and deliver to the Trustee a supplemental indenture substantially in the form of Annex A hereto pursuant to which such Subsidiary will become a Guarantor and (B) execute amendments to the Collateral Agreements pursuant to which it will grant a Lien on any Collateral held by it in favor of the Collateral Agent, for the benefit of the Secured Parties and become a Collateral Grantor thereunder and cause such Liens to be perfected as required thereby, and (2) deliver to the Trustee one or more Officers’ Certificates and Opinions of Counsel in connection with the foregoing as specified in this Indenture.

Subject to Article 5 , the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its existence.

65

(a) If a Change of Control occurs, the Company will make an offer (a “ Change of Control Offer ”) to each Holder to repurchase all or any part (equal to a minimum amount of $50,000 and integral multiples of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash (the “ Change of Control Payment ”) equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest and Additional Amounts, if any, on the Notes repurchased to the date of purchase (the “ Change of Control Payment Date ”), subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date. No later than 30 days following any Change of Control, the Company will mail a notice to the Trustee and Paying Agent and each Holder describing the transaction or transactions that constitute the Change of Control and stating:

(1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes properly tendered and not withdrawn pursuant to the Change of Control Offer will be accepted for payment;

(2) the Change of Control Payment and the Change of Control Payment Date, which will be no earlier than 30 days and no later than 60 days from the date such notice is mailed;

(3) that any Note not properly tendered will continue to accrue interest;

(4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest on and after the Change of Control Payment Date;

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, properly endorsed for transfer, together with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes completed and such customary documents as the Company may reasonably request, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day prior to the Change of Control Payment Date;

(6) that Holders will be entitled to withdraw their election if the Paying Agent receives, prior to the close of business on third Business Day preceding the Change of Control Payment Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing its election to have the Notes purchased; and

(7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $50,000 in principal amount or an integral multiple of $1,000 in excess thereof.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the extent those requirements, laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change

66

of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.15 , the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such compliance.

(b) On or before the Change of Control Payment Date, the Company shall, to the extent lawful:

(1) accept for payment all Notes or portions thereof properly tendered and not withdrawn pursuant to the Change of Control Offer;

(2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions Notes properly tendered and not withdrawn; and

(3) deliver or cause to be delivered to the Trustee and Paying Agent the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.

(c) The Paying Agent shall mail to each Holder of Notes properly tendered and not withdrawn the Change of Control Payment for such Notes (or, if all the Notes are then in global form, make such payment through the facilities of the Depository) and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided , however , that each such new Note will be in a principal amount of $50,000 or an integral multiple of $1,000 in excess thereof. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(d) Notwithstanding anything to the contrary in this Section 4.15 , the Company will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer, or (2) notice of redemption of all Notes has been given pursuant to Section 3.07 , unless there is a default in payment of the applicable redemption price.

(e) Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any cash consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture, any Subsidiary Guarantee or the Notes unless such consideration is offered to be paid and is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment.

67

(a) The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if:

(1) the Company would be permitted to make (i) a Permitted Investment or (ii) an Investment pursuant to Section 4.07 , in either case, in an amount equal to the Fair Market Value of all outstanding Investments owned by the Company and the Restricted Subsidiaries in such Subsidiary at the time of such designation;

(2) such Restricted Subsidiary meets the definition of an “Unrestricted Subsidiary”;

(3) the designation would not constitute or cause (with or without the passage of time) a Default or Event of Default and no Default and Event of Default would be in existence following such designation; and

(4) the Company delivers to the Trustee a certified copy of a resolution of the Board of Directors of Company giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.07 .

If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and the Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.07 or under one or more clauses of the definition of Permitted Investments, as determined by the Company.

If, at any time, any Unrestricted Subsidiary designated as such would fail to meet the preceding requirements as an Unrestricted Subsidiary, then such Subsidiary will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be Incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be Incurred as of such date under Section 4.09 , the Company or the applicable Restricted Subsidiary will be in default of such covenant.

(b) The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary if:

(1) the Company and the Restricted Subsidiaries could Incur the Indebtedness which is deemed to be Incurred upon such designation under Section 4.09 , equal to the total Indebtedness of such Subsidiary calculated on a pro forma basis as if such designation had occurred on the first day of the four-quarter reference period;

68

(2) the designation would not constitute or cause a Default or Event of Default; and

(3) the Company delivers to the Trustee a certified copy of a resolution of the Board of Directors of the Company giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions, including the Incurrence of Indebtedness under Section 4.09 .

The Company will not, and will not permit any of the Restricted Subsidiaries to, engage in any business other than Permitted Businesses, except to such extent as would not be material to the Company and the Restricted Subsidiaries taken as a whole.

(a) The Company will not permit any of its Subsidiaries (other than any Guarantor) to, be or become party to a Drilling Contract in respect of a Collateral Vessel (including as a charterer of a Collateral Vessel) or otherwise hold the right to directly receive any Earnings or any other Related Assets with respect to a Collateral Vessel; provided, that a Local Content Subsidiary may be a party to a Drilling Contract in respect of a Collateral Vessel or otherwise hold the right to receive Earnings or to any Related Assets with respect to a Collateral Vessel to the extent required by any law or regulation of any applicable jurisdiction, so long as such Local Content Subsidiary does not receive more than 20% of the Earnings or Related Assets with respect to such Collateral Vessel. The Company shall, or shall cause one or more of the Guarantors to, at all times maintain the Earnings Accounts, and each Earnings Account shall at all times be in the name of the Company or a Guarantor.

(b) The Company will at all times cause all such Earnings from the Drilling Contracts in respect of a Collateral Vessel to be deposited into or forwarded to the Earnings Accounts.

(a) All payments made by or on behalf of the Company or any Guarantor under or with respect to the Notes or the Subsidiary Guarantees will be made free and clear of and without withholding or deduction for, or on account of, any present or future tax, duty, levy, impost, assessment or other governmental charge of whatever nature (including penalties, additions to tax, interest and other liabilities related thereto) (hereinafter “ Taxes ”) unless the withholding or deduction of such Taxes is then required by law. If any deduction or withholding for, or on account of, any Taxes imposed or levied by or on behalf of the government of the Luxembourg, Liberia, Nigeria or any political subdivision or any authority or agency therein or thereof having power to tax, or any other jurisdiction in which the Company or any Guarantor (including any successor entity) is organized, incorporated, engaged in business or is otherwise resident or treated as resident for tax purposes, or any jurisdiction from or through which payment is made

69

(including, without limitation, the jurisdiction of each Paying Agent) (each a “ Specified Tax Jurisdiction ” and such Taxes, “ Indemnified Taxes ”), will at any time be required to be made from any payments made under or with respect to the Notes or the Subsidiary Guarantees, the Company, the relevant Guarantor or other payor, as applicable, will pay such additional amounts (the “ Additional Amounts ”) as may be necessary so that the net amount received in respect of such payments by each Holder after such withholding or deduction (including any withholding or deduction from Additional Amounts) will not be less than the amount such holder would have received if such Indemnified Taxes had not been withheld or deducted; provided , however , that Indemnified Taxes do not include:

(1) any Taxes to the extent such Taxes would not have been so imposed but for the Holder or beneficial owner of the Notes having any present or former connection with the Specified Tax Jurisdiction (other than the mere acquisition, ownership, holding, enforcement, exercise of rights or receipt of payment in respect of the Notes or the Subsidiary Guarantees);

(2) any estate, inheritance, gift, sales, excise, transfer, personal property Tax or similar Taxes;

(3) any Taxes to the extent such Taxes are imposed as a result of the failure of the Holder or beneficial owner of the Notes to complete, execute and deliver to the Company or the relevant Guarantor, as applicable, any form or document that such Holder or beneficial owner is legally entitled to complete, execute, and deliver, that may be required by law or by reason of administration of such law and that is reasonably requested in writing to be delivered to the Company or the relevant Guarantor in order to enable the Company or the relevant Guarantor to make payments on the Notes without deduction or withholding for Taxes, or with deduction or withholding of a lesser amount, which form or document will be delivered within 60 days of a written request therefor by the Company or the relevant Guarantor;

(4) any Taxes to the extent such Taxes would not have been so imposed but for the beneficiary of the payment having presented a Note for payment (in cases in which presentation is required) more than 30 days after the date on which such payment or such Note became due and payable or the date on which payment thereof is duly provided for, whichever is later (except to the extent that the Holder would have been entitled to Additional Amounts had the Note been presented on the last day of such 30-day period);

(5) any Taxes imposed on or with respect to any payment by the Company or any Guarantor to the Holder if such holder is a fiduciary or partnership or person other than the sole beneficial owner of such payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such partnership or the beneficial owner of such payment would not have been entitled to Additional Amounts had such beneficiary, settlor, member or beneficial owner been the actual holder of such Note;

(6) any Taxes to the extent such Taxes are required to be deducted or withheld on a payment pursuant to (a) European Council Directive 2003/48/EC (as amended or

70

replaced from time to time) or (b) any directive implementing the conclusion of the ECOFIN Council meeting of November 26-27, 2000 on the taxation of savings income, or (c) the bilateral agreements concluded between the European Union member States and several third countries or dependent or associated territories of the European Union pursuant to Article 17.2 of the European Council Directive 2003/48/EC (as amended or replaced from time to time), or (d) any law implementing, or introduced in order to conform to, such directive or (e) the Luxembourg law of 23 December 2005 in the taxation of interest income received by individuals resident in Luxembourg (so called “ Relibi Law ”);

(7) any Taxes to the extent such Taxes are imposed on a Note presented for payment by or on behalf of a Holder or beneficial owner who would have been able to avoid such Tax by presenting the relevant Note to another Paying Agent in a member state of the European Union;

(8) any Taxes to the extent such Taxes are payable other than by deduction or withholding at source; or

(9) any combination of items (1) through (8) above.

(b) If the Company or any Guarantor, as applicable, becomes obligated to pay Additional Amounts with respect to any payment under or with respect to the Notes or the Subsidiary Guarantees, the Company or the relevant Guarantor, as applicable, will deliver to the Trustee and Paying Agent at least 30 days prior to the date of that payment (unless the obligation to pay Additional Amounts arises after the 30th day prior to that payment date, in which case the Company or the relevant Guarantor, as applicable, will deliver to the Trustee and Paying Agent promptly thereafter but in no event later than five Business Days prior to the date of payment) an Officers’ Certificate stating the fact that Additional Amounts will be payable and the amount so payable. The Officers’ Certificate must also set forth any other information necessary to enable the Paying Agent to pay Additional Amounts to Holders on the relevant payment date. The Trustee and Paying Agent will be entitled to rely solely on such Officers’ Certificate as conclusive proof as to the amount of such payments and that such payments are necessary. The Company or the relevant Guarantor, as applicable, will provide the Trustee and Paying Agent with documentation reasonably satisfactory to the Trustee and Paying Agent evidencing the payment of Additional Amounts.

(c) The Company or the relevant Guarantor or applicable withholding agent, as applicable, will make all withholdings and deductions required by law and will remit the full amount deducted or withheld to the relevant governmental authority on a timely basis in accordance with applicable law. As soon as practicable, the Company or the relevant Guarantor or applicable withholding agent, as applicable, will provide the Trustee and Paying Agent with an official receipt or, if official receipts are not obtainable, other documentation reasonably satisfactory to the Trustee and Paying Agent evidencing the payment of the Taxes so withheld or deducted. Upon request, copies of those receipts or other documentation, as the case may be, will be made available by the Trustee and Paying Agent to the Holders.

71

(d) Whenever in this Indenture or the Notes there is referenced, in any context, the payment of amounts based upon the principal amount of the Notes or of principal, interest or any other amount payable under, or with respect to, the Notes or the Subsidiary Guarantees, such reference will be deemed to include payment of Additional Amounts as described in this Section 4.22 to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. For the avoidance of doubt, with respect to Notes represented by a Global Note, a Holder with respect to Additional Amounts and the related provisions of this Indenture shall be deemed to include a Holder representing the interests of a beneficial owner of the Notes or acting on behalf of a beneficial owner of the Notes.

(e) The Company or the relevant Guarantor, as applicable, will indemnify a Holder within 10 Business Days after written demand therefor, for the full amount of any Indemnified Taxes that were paid by such Holder to a governmental authority of a Specified Tax Jurisdiction and that were imposed on or with respect to any payment made under or with respect to the Notes or the Subsidiary Guarantees (including any Additional Amounts) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant governmental authority. A certificate as to the amount of such payment or liability delivered to the Company or the relevant Guarantor by a Holder will be conclusive absent manifest error.

(f) The Company or the relevant Guarantor, as applicable, will pay any present or future stamp, issue, registration, value added, court or documentary taxes or any other excise or property taxes, charges or similar levies (including penalties, additional amounts, interest and any other liabilities and reasonable expenses related thereto) that arise in any Specified Tax Jurisdiction from the execution, delivery, enforcement or registration of the Notes, the Subsidiary Guarantees, this Indenture or any other document or instrument in relation thereof, or the receipt of any payments with respect to the Notes or the Subsidiary Guarantees, and the Company or the relevant Guarantor, as applicable, will indemnify the Holders for any such taxes, charges, levies, penalties, amounts, interest, liabilities and expenses paid by such Holders.

(g) The obligations of the Company and the Guarantors under this Section 4.22 will survive any termination, defeasance or discharge of this Indenture and any transfer by a Holder of its Notes, and will apply mutatis mutandis to any jurisdiction in which any successor person to the Company or any Guarantor is organized, incorporated, engaged in business or is otherwise resident or treated as resident for tax purposes or any jurisdiction from or through which payment is made or any political subdivision or authority or agency thereof or therein.

From and after the first day (the “ Suspension Date ”) on which (1) the Notes have an Investment Grade Rating and (2) no Default or Event of Default has occurred and is continuing under this Indenture, the Company and its Restricted Subsidiaries will not be subject to the provisions of Sections 4.07 , 4.08 , 4.09 , 4.10 and 4.11 of this Indenture (collectively, the “ Suspended Covenants ”).

If at any date subsequent to the Suspension Date (each such date, a “ Reversion Date ”) Moody’s or S&P withdraws its ratings or downgrades the ratings assigned to the Notes so that

72

the Notes do not have an Investment Grade Rating, or an Event of Default (other than with respect to the Suspended Covenants) occurs and is continuing, then the Company and the Restricted Subsidiaries will, on and after the Reversion Date, be subject to the Suspended Covenants.

The period of time between the Suspension Date and the Reversion Date is referred to herein as the “ Suspension Period .” During the Suspension Period, the Board of Directors of the Company may not designate any of the Restricted Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.17 . Notwithstanding that the Suspended Covenants may be reinstated, no Default, Event of Default or breach of any kind under this Indenture or the Notes will be deemed to have occurred as a result of a failure of the Company and the Restricted Subsidiaries to comply with a Suspended Covenant during the Suspension Period.

Calculations made on and after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.07 will be made as if Section 4.07 had been in effect at all times since the Issue Date, including during the Suspension Period, except that no Default or Event of Default will be deemed to have occurred solely by reason of a Restricted Payment made while that covenant was suspended. On the Reversion Date, all Indebtedness Incurred during the continuance of the Suspension Period will be classified as having been incurred pursuant to clause (3)(ii) of Section 4.09(b) .

The Company will provide the Trustee with prompt written notice upon the commencement of a Suspension Period and of the occurrence of a Reversion Date.

(a) The Company will, and will cause each of its Restricted Subsidiaries to, (i) keep all material property necessary to the business of the Company and its Restricted Subsidiaries in good working order and condition (ordinary wear and tear and loss or damage by casualty or condemnation excepted) with such exceptions as would not reasonably be expected to have a material adverse effect on the operations, business, properties or financial condition of the Company and its Restricted Subsidiaries, taken as a whole, and (ii) furnish to the Collateral Agent, at the written request of the Collateral Agent, a complete description of the material terms of insurance carried on the Collateral Vessels.

(b) The Company will, and will cause each of its Restricted Subsidiaries to:

73

provided that neither the Company nor any of the Restricted Subsidiaries shall not be required to procure or maintain any insurance otherwise required to be procured or maintained under this clause (b), if such insurance is not commercially available in the commercial insurance market.

74

75

The Company shall, and shall cause each Collateral Grantor to, at the Company’s sole cost and expense:

(a) at the request of the Collateral Agent, acting at the direction of the Controlling Party, execute and deliver all such agreements and instruments and take all further action as may be reasonably necessary or desirable (i) to describe more fully or accurately the property intended to be Collateral or the obligations intended to be secured by any Collateral Agreement and/or (ii) to continue and maintain the Collateral Agent’s first-priority perfected security interest in the Collateral (subject to Permitted Collateral Liens and the Intercreditor Agreement); and

(b) at the request of the Collateral Agent, acting at the direction of the Controlling Party, file any such notice filings or other agreements or instruments as may be reasonably necessary or desirable under applicable law to perfect the Liens created by the Collateral Agreements.

The Company shall not permit any Collateral Grantor to enter into any agreement that requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or otherwise acquire or retire any Indebtedness of any Person, other than (i) the Notes, (ii) any other Pari Passu Obligations or (iii) otherwise as may be permitted or required by this Indenture, the Intercreditor Agreement and the Collateral Agreements, including with respect to any Permitted Collateral Liens; provided that any such agreement may be entered into to the extent that they permit such proceeds to be applied to Pari Passu Obligations prior to or instead of such other Indebtedness.

ARTICLE 5

(1) either (x) the Company will be the surviving or continuing Person or (y) the Person formed by or surviving any such amalgamation, consolidation or merger or to which such sale, assignment, transfer, conveyance or other disposition has been made is a Person organized or existing under the laws of a Permitted Jurisdiction (the Company or such Person, as the case may be, being herein called the “ Successor Company ”);

(3) immediately before and after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing;

(4) except with respect to a transaction solely between or among the Company and any of the Restricted Subsidiaries, immediately after giving pro forma effect to such transaction, any related financing transactions and the use of proceeds therefrom and treating any Indebtedness that becomes an obligation of the Company or any of the Restricted Subsidiaries as a result of such transaction as having been Incurred by the Company or such Restricted Subsidiary, as the case may be, at the time of the transaction, either (i) the Company or the Successor Company (if other than the Company) would be permitted to Incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Interest Coverage Ratio test set forth in Section 4.09(a) or (ii) the Company or the Successor Company (if other than the Company) would have a Consolidated Interest Coverage Ratio for the applicable four quarter period not lower than such ratio prior to giving effect to such transaction;

77

(2) either:

(i) (x) such Guarantor is the surviving Person or (y) the Person formed by or surviving any such consolidation or merger is a Person organized or existing under the laws of a Permitted Jurisdiction (such Guarantor or such Person, as the case may be, being herein called the “ Successor Guarantor ”) and the Successor Guarantor (if other than such Guarantor) expressly assumes all the obligations of such Guarantor under this Indenture and its Subsidiary Guarantee and any Collateral Agreements pursuant to a supplemental indenture, amendment or other documents or instruments in form and substance reasonably satisfactory to the Trustee; or

(ii) such consolidation or merger does not violate the provisions of Section 4.10 ;

(3) the Company delivers to the Trustee an Officers’ Certificate and Opinion of Counsel, each stating that such merger or consolidation and such supplemental indenture and each such amendment comply with this Section 5.01(b) ;

(4) if applicable, the Successor Guarantor causes such amendments, supplements or other instruments with respect to the Collateral Agreements to be executed, delivered, filed and recorded, as applicable, in such jurisdictions as may be required by applicable law to preserve and protect the Lien of the Collateral Agreements on any Collateral owned by or transferred to the Successor Guarantor and deliver an Opinion of Counsel as to the enforceability thereof and such other matters as the Trustee may reasonably request; and

(5) any Collateral owned by or transferred to the Successor Guarantor shall (i) continue to constitute Collateral under this Indenture and the Collateral Agreements, (ii) be subject to the Lien in favor of the Collateral Agent for the benefit of the holders of the Pari Passu Obligations and (iii) not be subject to any Lien other than Permitted Collateral Liens.

Upon any amalgamation, consolidation or merger, or any sale, assignment, transfer, conveyance or other disposition of all or substantially all of the properties or assets of the Company in accordance with Section 5.01 in which the Company is not the surviving entity, the Successor Company shall succeed to, and be substituted for (so that from and after the date of such amalgamation, consolidation or merger, sale, assignment, transfer, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer instead to the Successor Company and not to the Company), and may exercise every right and power of, the Company under this Indenture with the same effect as if the Successor Company had been named as the Company in this Indenture, and thereafter, the Company will be relieved of all obligations and covenants under this Indenture and the Notes and the Collateral Agreements to which the Company is a party.

(2) results in the acceleration of such Indebtedness prior to its Stated Maturity,

and, in either case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $25.0 million or more; provided , however, that if any such default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid, within a period of 60 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequential acceleration of the Notes shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree;

79

(f) failure by the Company or any of the Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $25.0 million, which judgments are not paid, discharged or stayed for a period of 60 days;

(g) (1) the Collateral Agreements shall for any reason cease to create a valid and perfected first-priority Lien (subject to payment priorities in favor of holders of Revolving Credit Agreement Obligations pursuant to the terms of the Intercreditor Agreement and subject to Permitted Collateral Liens) on any portion of the Collateral having a Fair Market Value in excess of $25.0 million (in each case, other than in accordance with the terms of this Indenture, the Intercreditor Agreement or the terms of the Collateral Agreements) or (2) the Company or any Restricted Subsidiary asserts in writing that any Lien created under the Collateral Agreements is invalid or unenforceable;

(h) except as permitted by this Indenture or any Subsidiary Guarantee, any Subsidiary Guarantee of a Significant Subsidiary is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor that is a Significant Subsidiary, or any Person duly acting on behalf of any such Guarantor, denies or disaffirms its obligations under its Subsidiary Guarantee; and

(i) the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, pursuant to or within the meaning of Bankruptcy Law:

(5) admits in writing it generally is not paying its debts as they become due; or

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

(1) is for relief against the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, in an involuntary case;

(2) appoints a Custodian (x) of the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, or (y) for all or

(3) orders the liquidation of the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary;

and the order or decree remains unstayed and in effect for 60 consecutive days.

If any Event of Default occurs and is continuing, the Trustee, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes, by notice to the Company and the Trustee, may (and the Trustee will, if directed by the Holders of at least 25% in aggregate principal amount of the then outstanding Notes) declare all the Notes to be due and payable immediately. Upon any such declaration, the Notes shall become due and payable immediately, together with all accrued and unpaid interest, Additional Amounts, if any, and premium, if any, thereon. Notwithstanding the preceding, if an Event of Default specified in clause (i) or (j) of Section 6.01 occurs with respect to the Company or any Guarantor, all outstanding Notes shall become due and payable immediately without further action or notice, together with all accrued and unpaid interest, Additional Amounts, if any, and premium, if any, thereon.

The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except with respect to nonpayment of principal, interest, premium or Additional Amounts, if any, that have become due solely because of the acceleration) have been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereon.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of and interest, premium, if any, and Additional Amounts, if any, on, the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

81

The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of principal of, premium, if any, interest, if any, or Additional Amounts, if any, on, the Notes (other than a payment Default or payment Event of Default that resulted from an acceleration that has been rescinded). 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, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

The Holders of a majority in aggregate principal amount of the then outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in any financial or personal liability. In case an Event of Default has occurred and is continuing, prior to taking any action hereunder, the Trustee shall be entitled to satisfactory indemnification or security (or both) against all loss, liability and expenses caused by the taking or not taking of such action.

Except to enforce the rights to receive payment of principal, premium, if any, or interest or Additional Amounts, if any, when due, pursuant to Section 6.07 , no Holder may pursue any remedy with respect to this Indenture or the Notes unless:

(a) such Holder has previously given the Trustee written notice that an Event of Default is continuing;

(b) Holders of at least 25% in aggregate principal amount of the then outstanding Notes have made a written request to the Trustee to pursue the remedy;

(c) such Holders have offered the Trustee, and the Trustee has received (if requested), security or indemnity (or both) satisfactory to it against any loss, liability or expense;

(d) the Trustee has not complied with such request within 60 days after its receipt of the request and the offer of security or indemnity (or both) satisfactory to it; and

(e) Holders of a majority in aggregate principal amount of the then outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period.

82

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

Notwithstanding any other provision of this Indenture, the rights of any Holder to receive payment of principal of, premium, if any, interest, if any, or Additional Amounts, if any, on, the Notes, on or after the respective due dates expressed in the Notes (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

If an Event of Default specified in Section 6.01(a) or (b)  occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company and the Guarantors for the whole amount of principal of, interest, premium, if any, and Additional Amounts, if any, remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and Additional Amounts, if any, and 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.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to 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 . To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. 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 Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

83

If the Trustee collects any money pursuant to this Article, subject to the Intercreditor Agreement, it shall pay out the money in the following order:

(a) First : to the Trustee and its agents and attorneys for amounts due under Section 7.06 , including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and costs and expenses of collection incurred by the Trustee;

(b) Second : to the Holders for amounts due and unpaid on the Notes for principal, premium, if any, interest, if any, and Additional Amounts, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, interest, if any, and Additional Amounts, if any, respectively; and

(c) Third : to the Company or to such other Person as a court of competent jurisdiction shall direct.

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10 .

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 , or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

Whenever in the exercise of any remedy available to the Trustee or the exercise of any trust or power conferred on it with respect to the Notes, the Trustee may also direct the Collateral Agent in the exercise of any of the rights and remedies available to the Collateral Agent pursuant to the Collateral Agreements.

ARTICLE 7

TRUSTEE

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

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

(d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01 .

(e) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. All money received by the Trustee shall, until applied as herein provided, be held in trust for the payment of the principal of, premium, if any, interest, if any, and Additional Amounts, if any, on the Notes.

(f) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability.

(g) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its rights to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder and in its capacity as Trustee under any other agreement executed in connection with this Indenture to which the Trustee is a party.

85

(a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel of its own selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

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

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture; provided that the Trustee’s conduct does not constitute willful misconduct or gross negligence.

(e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company.

(f) If an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any Holders unless such Holders have offered to the Trustee, and the Trustee has received, indemnity or security (or both) satisfactory to it against any loss, liability or expense that might be incurred by it in compliance with such request or direction.

(g) The Trustee shall not be deemed to have knowledge of any Default or Event of Default except: (1) any Event of Default occurring pursuant to Section 6.01(a) or 6.01(b) ; or (2) any Default or Event of Default of which a Responsible Officer of the Trustee shall have received written notification or obtained actual knowledge.

(h) The permissive rights of the Trustee to act hereunder shall not be construed as a duty.

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

(j) The Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and titles of officers authorized at such times to take specified actions pursuant to this Indenture.

86

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company, any Guarantor or any of their Affiliates with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as defined in the Trust Indenture Act of 1939, amended), it must eliminate that conflict within 90 days or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.09 .

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes or any other Note Document, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

If a Default or Event of Default occurs and is continuing and if, in accordance with Section 7.02(g) , the Trustee has knowledge thereof, the Trustee shall mail to the Holders a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, or interest, premium, or Additional Amounts, if any, on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders.

The Company shall pay to the Trustee from time to time such reasonable compensation as the Company and the Trustee may agree in writing for the Trustee’s acceptance of this Indenture and services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

The Company and the Guarantors shall indemnify the Trustee, jointly and severally, against any and all losses, liabilities, damages, claims or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses (including, without limitation, fees and expenses of counsel) of enforcing

87

this Indenture against the Company and the Guarantors (including this Section 7.06 ) and defending itself against any claim (whether asserted by the Company, any Guarantor or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability, damage, claim or expense may be attributable to its gross negligence or willful misconduct. The Trustee shall notify the Company and the Guarantors promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company and the Guarantors shall not relieve the Company or the Guarantors of their obligations hereunder. The Company and the Guarantors shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company and the Guarantors shall pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

The obligations of the Company and the Guarantors under this Section 7.06 shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee.

To secure the Company’s and the Guarantors’ payment obligations in this Section 7.06 , the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal, premium, if any, and interest or Additional Amounts, if any, on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(i) or 6.01(j) occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

The immunities, protections and exculpations available to the Trustee under this Indenture shall also be available to each Agent, and the Company’s and each Guarantor’s obligations under this Section 7.06 to compensate and indemnify the Trustee shall extend likewise to each Agent.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.07 .

The Trustee may resign in writing upon thirty (30) days notice at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing and may appoint a successor trustee with the consent of the Company. The Company may remove the Trustee if:

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

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

88

(c) a receiver, Custodian or public officer takes charge of the Trustee or its property; or

(d) the Trustee becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least 10% of the aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction, at the expense of the Company, for the appointment of a successor Trustee.

If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply with Section 7.09 , such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of 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 the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.06 . Notwithstanding replacement of the Trustee pursuant to this Section 7.07 , the Company’s and the Guarantors’ obligations under Section 7.06 shall continue for the benefit of the retiring Trustee.

If the Trustee consolidates with, or merges or converts into, or transfers or sells all or substantially all of its corporate trust business or assets to, another corporation or banking association, the successor corporation or banking association without any further act shall be the successor Trustee. As soon as practicable, the successor Trustee shall mail a notice of its succession to the Company and the Holders.

There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. No obligor upon the Notes shall serve as a Trustee.

89

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

The Company may, at any time, elect to have either Section 8.02 or 8.03 be applied with respect to all outstanding Notes and all obligations of the Guarantors upon compliance with the conditions set forth below in this Article 8 .

Upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.02 , subject to the satisfaction of the conditions set forth in Section 8.04 , the Company shall be deemed to have discharged its obligations with respect to all outstanding Notes and, to the extent related to the Notes and the Subsidiary Guarantees, the Collateral Agreements to which it is a party, each Guarantor shall be deemed to have discharged its obligations with respect to its Subsidiary Guarantee and, to the extent related to the Notes and the Subsidiary Guarantees, the Collateral Agreements to which it is a party and each other Collateral Grantor shall be deemed to have discharged its obligations with respect to the Collateral Agreements, to the extent related to the Notes and the Subsidiary Guarantees, to which it is a party, on the date the conditions set forth in Section 8.04 below are satisfied (hereinafter, “ Legal Defeasance ”). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, and each Guarantor shall be deemed to have paid and discharged its Subsidiary Guarantee (which in each case shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in clauses (a) and (b) below) and to have satisfied all its other obligations under the Notes or such Subsidiary Guarantees and this Indenture, and the Company and the other Collateral Grantors shall be deemed to have satisfied all of their obligations under the Collateral Agreements, to the extent related to the Notes and the Subsidiary Guarantees (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, and premium, interest or Additional Amounts, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04 ;

(b) the Company’s obligations with respect to the Notes under Sections 2.03 , 2.04 , 2.06 , 2.07 , 2.10 and 4.02 and the Appendix;

(c) the rights, powers, trusts, duties, indemnities and immunities of the Agents, and the Company’s and the Guarantors’ obligations in connection therewith and under Section 7.06 ; and

(d) the Legal Defeasance and Covenant Defeasance provisions of this Article 8 .

Subject to compliance with this Article 8 , the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 .

90

Upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03 , the Company and each of the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 , be released from their respective obligations under the covenants contained in Article 4 (other than those in Sections 4.01 , 4.02 , 4.04 , 4 .06 , 4.14 , 4.22 and 4.23 ) and in clause (4) of Section 5.01(a) and in Article 11 and under all Collateral Agreements, to the extent related to the Notes and the Subsidiary Guarantees, to which it is a party on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, “ Covenant Defeasance ”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Subsidiary Guarantees, the Company and any Guarantor may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 , but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03 , subject to the satisfaction of the conditions set forth in Section 8.04 , Section 6.01(d)(2) and Sections 6.01(e) through 6.01(h) shall not constitute Events of Default.

In order to exercise either Legal Defeasance or Covenant Defeasance:

(a) the Company must irrevocably deposit with the Paying Agent, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, and premium, if any, and interest and Additional Amounts, if any, on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption date;

(b) in the case of an election under Section 8.02 , the Company shall have delivered to the Trustee, the Registrar and the Paying Agent an Opinion of Counsel reasonably acceptable to the Trustee confirming that:

(1) the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or

(2) since the Issue Date, there has been a change in the applicable federal income tax law,

91

in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(c) in the case of an election under Section 8.03 , the Company shall have delivered to the Trustee, the Registrar and the Paying Agent an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from, or otherwise in connection with, the borrowing of funds to be applied to such deposit pursuant to this Section 8.04 (and any similar concurrent deposit relating to other Indebtedness) or the grant of any Lien securing such borrowing);

(e) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound;

(f) the Company must deliver to the Trustee, the Registrar and the Paying Agent an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over the other creditors of the Company or any Guarantor with the intent of defeating, hindering, delaying or defrauding any creditors of the Company, any Guarantor or others; and

(g) the Company shall have delivered to the Trustee, the Registrar and the Paying Agent an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Subject to Section 8.06 , all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee pursuant to Section 8.04 or 8.08 in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company or any of its Subsidiaries acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, interest, premium, if any, and Additional Amounts, if any, but such money need not be segregated from other funds except to the extent required by law.

92

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 or 8.08 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the written request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 or 8.08 which, in the opinion of a nationally recognized investment banking, appraisal firm or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) ), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance, Covenant Defeasance or Discharge, as the case may be.

Subject to applicable escheat and abandoned property laws, any money or non-callable Government Securities deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, or interest, premium, if any, or Additional Amounts, if any, on, any Note and remaining unclaimed for two years after such principal, interest, premium, if any, or Additional Amounts, if any, has become due and payable shall be paid to the Company on its written request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money or non-callable Government Securities, and all liability of the Company as trustee thereof, shall thereupon cease; provided , however , that the Trustee or such Paying Agent, before being required to make any such repayment, shall at the written request and expense of the Company cause to be published once, in the New York Times or The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

If the Trustee or the Paying Agent is unable to apply any money or non-callable Government Securities 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 and the Guarantors’ obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 until such time as the Trustee or the Paying Agent is permitted to apply all such money in accordance with Section 8.05 ; provided , however , that, if the Company or any Guarantor makes any payment of principal of, interest, premium, if any, or Additional Amounts, if any, on, any Note following the reinstatement of its obligations, the Company or such Guarantor, as

93

applicable, shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities deposited with or held by the Trustee or the Paying Agent.

This Indenture, the Subsidiary Guarantees and , to the extent related to the Notes and the Subsidiary Guarantees, all Collateral Agreements shall be discharged and shall cease to be of further effect as to all Notes issued hereunder (except as to (x) the rights of Holders of outstanding Notes to receive solely from the trust fund described in clause (1)(b) of this Section 8.08 , and as more fully set forth in such clause (1)(b), payments in respect of the principal of and interest, premium, if any, and Additional Amounts, if any, on, such Notes when such payments are due, (y) the Company’s obligations with respect to such Notes under Sections 2.03 , 2.04 , 2.05 , 2.06 , 2.07 , 2.10 and 4.02 and the Appendix and (z) the rights, powers, trusts, duties and immunities of the Trustee and each Agent hereunder and the Company’s obligations in connection therewith), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture with respect to all the Notes, when:

(1) either:

(a) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or

(b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable or will become due and payable within one year by reason of the mailing of a notice of redemption or otherwise and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Paying Agent as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, accrued interest, premium, if any, interest, if any, and Additional Amounts, if any, to the date of fixed maturity or redemption;

(2) in respect of clause (1)(b) of this Section 8.08 , the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings);

94

(3) the Company or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture;

(4) the Company has delivered irrevocable instructions to the Trustee, the Registrar and the Paying Agent to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be; and

(5) the Company has delivered (a) an Officers’ Certificate to the Trustee, the Registrar and the Paying Agent stating that all conditions precedent to satisfaction and discharge of this Indenture (“ Discharge ”) have been satisfied and (b) an Opinion of Counsel to the Trustee, the Registrar and the Paying Agent stating that all conditions precedent to Discharge have been satisfied.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

Notwithstanding the provisions of Section 9.02 , without the consent of any Holder, the Company, the Guarantors, the Trustee and, if any amendment relates to or any Collateral Agreement, the Collateral Agent, may amend or supplement this Indenture, the Notes, the Subsidiary Guarantees, the Intercreditor Agreement and the Collateral Agreements in the following circumstances:

(a) to cure any ambiguity, defect or inconsistency;

(b) to provide for uncertificated Notes in addition to or in place of certificated Notes;

(d) to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights under this Indenture of any such Holder in any material respect;

(e) to conform the text of this Indenture, the Notes, the Subsidiary Guarantees, the Intercreditor Agreement or the Collateral Agreements to any provision of the “Description of Notes” in the Offering Memorandum to the extent that such provision in such “Description of Notes” was intended to set forth, verbatim or in substance, a provision of this Indenture, the Intercreditor Agreement, the Notes, the Subsidiary Guarantees or the Collateral Agreements, which intent may be evidenced by an Officers’ Certificate to that effect;

(f) to evidence and provide for the acceptance of the appointment under this Indenture, the Intercreditor Agreement and the Collateral Agreements of a successor Trustee or Collateral Agent;

95

(g) to enter into additional or supplemental Collateral Agreements and to add additional assets as Collateral to secure the Notes and the Subsidiary Guarantees;

(h) to release Collateral or any Subsidiary Guarantee when permitted or required by this Indenture, the Intercreditor Agreement or the Collateral Agreements or to amend or supplement any Collateral Agreement in accordance with the Intercreditor Agreement or the Collateral Agreements;

(i) to allow any Guarantor to execute a supplemental indenture and/or a Subsidiary Guarantee with respect to the Notes and to add any additional Guarantor;

(j) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture;

(m) to comply with requirements of the Trust Indenture Act of 1939, as amended, if applicable, the Irish Stock Exchange or any other securities exchange on which the Notes are listed for trading or quotation; or

(n) with respect to any Collateral Agreement, as provided in the Intercreditor Agreement.

Upon the request of the Company, and upon receipt by the Trustee of the documents described in Section 9.06 , the Trustee shall join with the Company and the Guarantors in the execution of any amendment or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into any such amendment or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Except as provided above in Section 9.01 and below in this Section 9.02 , the Company, the Guarantors, the Trustee and the Collateral Agent may amend or supplement this Indenture, the Notes and the Collateral Agreements by the execution of a supplemental indenture or, in the case of any amendment or supplement to the Collateral Agreements, by the execution of an appropriate amendment or supplement thereto, with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) and, subject to Sections 6.04 and 6.07 , any existing Default or Event of Default or compliance with any provision of this Indenture, the Notes, the Subsidiary Guarantees, the

96

Intercreditor Agreement or any Collateral Agreement may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), in each case in addition to any required consent of holders of other Pari Passu Obligations that may be required with respect to an amendment of or waiver under a Collateral Agreement or the Intercreditor Agreement. However, without the consent of each Holder of an outstanding Note affected thereby, an amendment, supplement or waiver may not (with respect to any Notes held by a non-consenting Holder):

(a) reduce the percentage of principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

(b) reduce the principal of, or change the fixed maturity of, any Note or alter the provisions with respect to the redemption of the Notes (other than with respect to minimum notice required for redemption or the provisions of Sections 4.10 and 4.15 ), including any provision relating to the premium payable upon any such purchase or redemption;

(c) reduce the rate of or change the time for payment of interest, including default interest, on any Note;

(d) impair the rights of any Holder of Notes to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the redemption date);

(e) waive a Default or Event of Default in the payment of principal of, or premium, if any, interest, if any, or Additional Amounts, if any, on, the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment Default that resulted from such acceleration);

(f) make any Note payable in money other than that stated in the Notes;

(g) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders to receive payments of principal of, or premium, if any, interest, if any, or Additional Amounts, if any, on, the Notes;

(h) waive a redemption payment with respect to any Note (other than a payment required by Section 3.08 , 3.09 , 4.10 or 4.15) ;

(i) release any Guarantor from any of its obligations under its Subsidiary Guarantee or this Indenture, except in accordance with the terms of this Indenture; or

(j) make any change in the preceding amendment, supplement and waiver provisions.

In addition, except as otherwise provided in this Indenture, the Intercreditor Agreement and the Collateral Agreements, the consent of Holders of at least two-thirds in aggregate principal amount of the then outstanding Notes will be required to release the Liens for the benefit of the Holders on all or substantially all of the Collateral.

97

Upon the request of the Company and upon the receipt by the Trustee of evidence satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06 , the Trustee shall join with the Company and the Guarantors in the execution of such amendment, supplement or waiver, unless such amendment, supplement or waiver affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amendment, supplemental indenture or waiver.

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

A consent to any amendment, supplement or waiver under this Indenture by any Holder given in connection with a purchase, tender or exchange of such Holder’s Notes shall not be rendered invalid by such purchase, tender or exchange.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of such Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and, except as provided in the second succeeding paragraph, thereafter binds every Holder.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the second to last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment, supplement or waiver or revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date except to the extent that the requisite number of consents to the amendment, supplement or waiver have been obtained within such 90-day period or as set forth in the next paragraph of this Section 9.04 .

98

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses (a) through (j) of Section 9.02 , in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same indebtedness as the consenting Holder’s Note.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company, in exchange for all Notes, may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

The Trustee shall sign any amendment or supplemental indenture or grant any waiver authorized pursuant to this Article 9 if the amendment or supplemental indenture or waiver does not adversely affect its rights, duties, liabilities or immunities. If any such amendment, supplemental indenture or waiver does adversely affect the rights, duties, liabilities or immunities of the Trustee, the Trustee may, but need not, sign such amendment, supplemental indenture or grant such waiver. In executing any such amendment, supplemental indenture or waiver, the Trustee shall be entitled to receive and (subject to Section 7.01 ) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment, supplemental indenture or waiver is authorized or permitted by this Indenture.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given, made or taken by Holders shall be in writing may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “ Act ” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 7.01 ) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section.

Without limiting the generality of this Section, unless otherwise provided in or pursuant to this Indenture, (i) a Holder, including the Depository or its nominee that is a Holder of a Global Note, may give, make or take, by an agent or agents duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in or pursuant to this Indenture to be given, made or taken by Holders, and the Depository or its nominee that is a Holder of a Global Note may duly appoint in writing as its agent or agents

99

members of, or participants in, the Depository holding interests in such Global Note in the records of the Depository; and (ii) with respect to any Global Note, any consent or other action given, made or taken by an Agent Member by electronic means in accordance with the “Automated Tender Offer Procedures” system or other customary procedures of, and pursuant to authorization by, the Depositary shall be deemed to constitute the Act of the Holder of such Global Note, and such Act shall be deemed to have been delivered to the Company and the Trustee upon the delivery by the Depositary of an “agent’s message” or other notice of such consent or other action having been so given, made or taken in accordance with the applicable policies and procedures of the Depositary.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a Person acting in a capacity other than such Person’s individual capacity, such certificate or affidavit shall also constitute sufficient proof of the authority of the Person executing the same. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

(c) The ownership of Notes shall be proved by the Register.

(d) Without limiting the foregoing, a Holder entitled hereunder to give, make or take any action hereunder with regard to any particular Note may do so, or duly appoint in writing any Person or Persons as its agent or agents to do so, with regard to all or any part of the principal amount of such Note.

ARTICLE 10

GUARANTEES OF NOTES

Subject to this Article 10 , each of the Guarantors hereby absolutely and unconditionally guarantees, jointly with the other Guarantors and severally, as primary obligor and not merely as surety, on a senior basis to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and their respective successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the Obligations of the Company hereunder and thereunder, that:

(a) the principal of, and premium, if any, interest, if any, on, or Additional Amounts, if any, on, the Notes will be promptly paid in full when due, whether at Stated Maturity, by acceleration, upon repurchase or redemption or otherwise, and interest on the overdue principal of, and premium, if any, and (to the extent permitted by law) interest, if any, on, and Additional Amounts, if any, on, the Notes, and all other payment Obligations of the Company to the Holders or the Trustee under this Indenture or the Notes will be promptly paid in full and performed, all in accordance with the terms hereof and thereof; and

(b) in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at Stated Maturity, by acceleration, upon repurchase or redemption or otherwise.

100

Failing payment when so due of any amount so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is an absolute, unconditional, present and continuing guarantee of payment and performance (and not a guarantee of collection) and is in no way conditioned upon any attempt to collect from the Company or any other Guarantor or any other action, occurrence or circumstance whatsoever.

The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance (other than complete performance) which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor further, to the extent permitted by law, hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Subsidiary Guarantee will not be discharged except by complete performance of the Obligations contained in the Notes and this Indenture.

If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors, or any Custodian, trustee or other similar official acting in relation to any of the Company or the Guarantors, any amount paid by the Company or any Guarantor to the Trustee or such Holder, the Subsidiary Guarantees, to the extent theretofore discharged, shall be reinstated in full force and effect.

Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (a) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of such Obligations as provided in Article 6 , such Obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of its Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantees.

The Subsidiary Guarantee of a Guarantor will be automatically and unconditionally released: (1) in connection with any sale or other disposition of all or substantially all of the properties or assets of such Guarantor (including by way of merger, consolidation or amalgamation) to a Person that is not (either before or after giving effect to such transaction) the

101

Company or a Restricted Subsidiary, if the sale or other disposition is conducted in accordance with Sections   4.10 and 5.01(b) , as applicable; (2) in connection with any sale or other disposition of the Capital Stock of such Guarantor, following which such Guarantor is no longer a Restricted Subsidiary of the Company, if the sale or other disposition is conducted in accordance with Sections   4.10 and 5.01(b) , as applicable; (3) upon Legal Defeasance, Covenant Defeasance or Discharge in accordance with Article 8 ; (4) unless an Event of Default has occurred and is continuing, upon the dissolution or liquidation of such Guarantor in compliance with Section 5.01(b) ; or (5) unless an Event of Default has occurred and is continuing, if such Guarantor ceases to have interests in Collateral that would require it to become a Guarantor under Section 4.13 .

Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that any of the conditions described in the foregoing clauses (1) through (5) has occurred, the Trustee shall execute any documents reasonably requested by the Company at the Company’s expense in order to evidence the release of any Guarantor (other than the Company) from its obligations under its Subsidiary Guarantee. Any Guarantor not released from its obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of and interest, premium, if any, and Additional Amounts, if any, on, the Notes and for the other obligations of such Guarantor under this Indenture as provided in this Article 10 .

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state or foreign law to the extent applicable to any Subsidiary Guarantee. The obligations of each Guarantor under its Subsidiary Guarantee will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state or foreign law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally. Each Guarantor that makes a payment under its Subsidiary Guarantee shall be entitled, upon payment in full of all guaranteed Obligations under this Indenture, to seek contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all Guarantors at the time of such payment determined in accordance with GAAP.

In case at any time any Paying Agent other than the Trustee shall have been appointed and be then acting hereunder, the term “Trustee” as used in this Article 10 shall in each case (unless the context shall otherwise require) be construed as extending to and including such Paying Agent within its meaning as fully and for all intents and purposes as if such Paying Agent were named in this Article 10 in place of the Trustee.

102

The execution by each Guarantor of this Indenture (or a supplemental indenture hereto) evidences the Subsidiary Guarantee of such Guarantor, whether or not the person signing as an Officer of the Guarantor still holds that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of each Guarantor.

Each Guarantor shall be subrogated to all rights of Holders against the Company in respect of any amounts paid by the Guarantor pursuant to the provisions of Section 10.01 ; provided that no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Company under this Indenture or the Notes shall have been paid in full.

The obligations of a Guarantor incorporated in Luxembourg (each, a “ Luxembourg Guarantor ”) under this Article 10 shall at all times be limited to an aggregate amount not exceeding the greater of:

(a) 90% of such Luxembourg Guarantor’s own funds (“ capitaux propres ”, as referred to in article 34 of the Luxembourg law of 19 December 2002 on the commercial register and annual accounts, as amended by the law of 10 December 2010 on the introduction of international accounting standards for undertakings) as reflected in its last annual accounts duly approved and available on the date of the enforcement of the Subsidiary Guarantee of such Guarantor; or

(b) 90% of such Luxembourg Guarantor’s own funds (“ capitaux propres ”, as referred to in article 34 of the Luxembourg law of 19 December 2002 on the commercial register and annual accounts, as amended by the law of 10 December 2010 on the introduction of international accounting standards for undertakings) as reflected in its last annual accounts duly approved and available on the effective date of the Subsidiary Guarantee of such Guarantor,

except, in each case, to the extent that the Subsidiary Guarantee relates to the obligations of a direct or indirect subsidiary of the relevant Luxembourg Guarantor.

(a) Security Agreements . In order to secure the due and punctual payment of the Pari Passu Obligations, (i) on the Issue Date, simultaneously with the execution and delivery of this Indenture, the Guarantors have executed Collateral Agreements granting to the Collateral Agent for the benefit of the Secured Parties (in accordance with the Intercreditor Agreement) a first-priority

103

perfected Lien in the Collateral, and (ii) after the Issue Date, in accordance with the provisions of Sections 4.13 and 4.26 and this Article 11 , if (I) any asset of the type which is required to constitute Collateral pursuant to this Indenture or the Collateral Agreements is acquired by any Guarantor and such asset is not automatically subject to a first-priority perfected Lien in favor of the Collateral Agent or (II) a Subsidiary of the Company that is not already a Guarantor is required to become a Guarantor pursuant to Section 4.13 , then such Guarantor or such other Subsidiary shall, as soon as practicable after the acquisition of the applicable asset or the occurrence of the event requiring such Subsidiary to become a Guarantor (and, in any event, within 20 Relevant Business Days after such acquisition or event), execute and deliver the necessary Collateral Agreements in order to grant to the Collateral Agent a first-priority perfected Lien in all assets of such Guarantor or such other Subsidiary which are required to, but do not already, constitute Collateral. In each case described above, each Guarantor shall execute and deliver such other Collateral Agreements, deliver any certificates to the Collateral Agent in respect of the applicable Collateral as required by this Indenture and the applicable Collateral Agreements and take all other appropriate actions to ensure the Collateral Agent, for the benefit of the Secured Parties, has a first-priority perfected Lien therein. For the avoidance of doubt, the Guarantors shall not be required to grant a security interest in, and the Collateral shall not include, any Excluded Property, the Guarantors shall not be required to execute an assignment of any Drilling Contract, and in no event shall any Guarantor be required to take actions to perfect the Collateral Agent’s security interest in trucks, trailers and other motor vehicles covered by a certificate of title under the law of any state.

The Company shall cause every Guarantor to make all filings (including filings of continuation statements and amendments to Uniform Commercial Code financing statements in the United States (or the applicable political subdivision, territory or possession thereof) that may be necessary to continue the effectiveness of such Uniform Commercial Code financing statements) and take all other actions as are reasonably necessary or required by the Collateral Agreements to maintain (at the sole cost and expense of the Guarantors) the security interest created by the Collateral Agreements in the Collateral as a first-priority perfected Lien.

All references to a “first-priority perfected Lien” in this Section 11.01(a) shall be understood to be subject to Permitted Collateral Liens, if any and the terms of the Intercreditor Agreement.

(b) Additional Collateral . The Company shall, and shall cause every other Collateral Grantor to, from time to time take the actions required by Section 4.26 .

Section 11.02 [Reserved] .
