If required by the Registrar or the Issuer, such Holder shall furnish an indemnity bond sufficient in the judgment of the Registrar, the Trustee and the Issuer to protect the Issuer, the Trustee, the Paying Agent and the Registrar from any loss which any of them may suffer if a Note is replaced.

Until definitive Notes are ready for delivery, the Issuer may prepare and the Trustee shall, upon its receipt of an authentication order from the Issuer, authenticate temporary Notes.

Holders of temporary Notes shall be entitled to all of the benefits under this Indenture.

The Issuer at any time may deliver Notes to the Trustee for cancellation.

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 Issuer unless the Issuer directs the Trustee to deliver canceled Notes to the Issuer instead.

The Issuer 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 , 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.

If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuer 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 Issuer shall issue in the name of the applicable Holder and the Trustee shall, upon its receipt of an authentication order from the Issuer, authenticate for such Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

(a) At any time prior to December 1, 2015, the Issuer 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 107.250% 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 Parent of 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 Parent 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 December 1, 2015, the Issuer 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 December 1, 2015, not more than once in any 12-month period, the Issuer may redeem up to $50.0 million (representing 10% of the original principal amount of the Notes) 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 December 1, 2015, the Issuer 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 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 December 1 of the years indicated below:

(e) The Issuer 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 Issuer determines in good faith that the Issuer 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 Note Guarantees, Additional Amounts, and such obligation cannot be avoided by taking reasonable measures available to the Issuer 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 Issuer 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 Issuer or the relevant Guarantor, as applicable, would be obligated to pay Additional Amounts if a payment in respect of the Notes or the Note Guarantees were then due, and at the time such notice is given, the obligation to pay Additional Amounts must remain in effect. Before the Issuer mails or delivers notice of redemption of the Notes as described above, the Issuer will deliver to the Trustee and Paying Agent (a) an Officers’ Certificate stating that the Issuer is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Issuer to so redeem have occurred and (b) an opinion of independent legal counsel of recognized standing satisfactory to the Trustee and Paying Agent that the Issuer 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 accept and 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 Issuer shall deposit or cause to be deposited all Event of Loss Proceeds in the Earnings Account 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 Issuer may withdraw such Event of Loss Proceeds from the Earnings Account to redeem the Notes 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 Issuer shall redeem Notes 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 Issuer 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 matters specified in clauses (a) through (h) of Section 3.03 , that the Notes are being redeemed with Event of Loss Proceeds.

(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 therein.

(a) In the event that, pursuant to Section 4.10 , the Issuer 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 ”). No later than five Business Days after the termination of the Asset Sale Offer Period (the “ Asset Sale Offer Settlement Date ”), the Issuer shall apply all Excess Proceeds (the “ Asset Sale Offer Amount ”) to the purchase of the Notes and unsubordinated Indebtedness of the Parent or the applicable Restricted Subsidiary as specified in Section 4.10 or, if less than the Asset Sale Offer Amount has been validly tendered (and not validly withdrawn), all Notes and unsubordinated Indebtedness of the Parent or such Restricted Subsidiary, as applicable, validly tendered (and not validly withdrawn) in response to the Asset Sale Offer.

(c) Upon the commencement of an Asset Sale Offer, the Issuer shall send, by first class mail, a notice to each of the Holders, with a copy to the Trustee. 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. The notice, which shall govern the terms of the Asset Sale Offer, shall state:

(i) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 and the length of time the Asset Sale Offer shall remain open, including the time and date the Asset Sale Offer will terminate (the “ Asset Sale Offer Termination Date ”);

(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;

(iv) that, unless the Issuer defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer shall cease to accrue interest on and after the Asset Sale Offer Settlement Date;

(v) that Holders electing to have a Note purchased pursuant to any Asset Sale Offer shall be required to surrender the Note, properly endorsed for transfer, together with the form entitled “Option of Holder to Elect Purchase” on

the reverse of the Note completed and such customary documents as the Issuer may reasonably request, to the Issuer or a Paying Agent at the address specified in the notice, before the Asset Sale Offer Termination Date;

(vi) that Holders shall be entitled to withdraw their election if the Issuer or the Paying Agent, as the case may be, receives, prior to the Asset Sale Offer Termination Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have such Note purchased;

(vii) that, if the aggregate principal amount of Notes surrendered by Holders and, in the case of Excess Proceeds received in respect of assets not constituting Collateral, unsubordinated Indebtedness of the Parent 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 $200,000 and integral multiples of $1,000 in excess thereof will be outstanding after such purchase) and, if applicable, the Issuer will select such unsubordinated 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 $200,000 in principal amount or an integral multiple of $1,000 in excess thereof.

Promptly after the Asset Sale Offer Termination Date, the Issuer shall, to the extent lawful, accept for payment Notes or portions thereof tendered pursuant to the Asset Sale Offer in the aggregate principal amount required by Section 4.10 . Prior to 11:00 a.m., New York City time, on the Asset Sale Offer Settlement Date, the Issuer, 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 Issuer for purchase, and the Issuer shall promptly issue a new Note, and the Trustee shall, upon its receipt of an authentication order from the Issuer, 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. Any Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer shall publicly announce the results of the Asset Sale Offer on or before the Asset Sale Offer Settlement Date.

Except as set forth under Sections 3.08 , 4.10 , 4.15 and 4.19 , the Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes or to repurchase the Notes at the option of the Holders.

The Issuer shall pay or cause to be paid the principal of, interest, premium, if any, on, the Notes on the dates and in the manner provided in the Notes. Principal, interest and premium, if any, shall be considered paid on the date due if the Paying Agent, if other than the Parent or a Subsidiary thereof, holds as of 11:00 a.m., New York City time, on the due date money deposited by the Issuer or a Guarantor in immediately available funds and designated for and sufficient to pay all principal, interest and premium, if any, then due. Subject to Section 4.22 , all payments made by the Issuer under or with respect to the Notes will be made free and clear of and without withholding or deduction for, or on account of, any Taxes, unless the withholding or deduction of such Taxes is then required by law.

The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate equal to the then-applicable interest rate on the Notes; and it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if any (without regard to any applicable grace period), at the same rate as on overdue principal to the extent lawful.

The Issuer shall maintain an office or agency (which may be an office of the Trustee, an affiliate of the Trustee, the Registrar or the Paying Agent) in New York, New York where Notes may be presented or surrendered for payment and shall maintain an office or agency in the United States (which may be an office of the Trustee, an affiliate of the Trustee, the Registrar or the Paying Agent) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served. The Issuer shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Issuer 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 Issuer of its obligation to maintain an office or agency in New York, New York for such purposes. The Issuer shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Issuer hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Issuer in accordance with Section 2.03 .

(a) Whether or not the Parent is then subject to Section 13(a) or 15(d) of the Exchange Act, the Parent shall furnish to the Trustee and the Holders, so long as any Notes are outstanding:

(1) within 75 days after the end of each of the first three fiscal quarters in each fiscal year, reports on Form 6-K (or any successor form) containing, whether or not required, the Parent’s unaudited quarterly consolidated financial statements (including a balance sheet and statement of income, changes in stockholders’ equity and cash flow) and a Management’s Discussion and Analysis of Financial Condition and Results of Operations (the “ MD&A ”) (or equivalent disclosure) for and as of the end of such fiscal quarter (with comparable financial statements for the corresponding fiscal quarter of the immediately preceding fiscal year);

(2) within the time period required under the rules of the SEC for the filing of Form 20-F (or any successor form) for each fiscal year, an annual report on Form 20-F (or any successor form) containing the information required to be contained therein (including the Parent’s audited consolidated financial statements, a report thereon by the Parent’s certified independent accountants and an MD&A) for such fiscal year; and

(3) at or prior to such times as would be required to be filed or furnished to the SEC if the Parent was then a “foreign private issuer” subject to Section 13(a) or 15(d) of the Exchange Act (whether or not the Parent is then subject to such requirements), all such other reports and information that the Parent would have been required to file or furnish pursuant thereto.

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

(b) If the Issuer is ever required to file periodic reports with the SEC under Section 13 or Section 15(d) of the Exchange Act, the Issuer shall timely file with the SEC all required periodic reports so long as any Notes remain outstanding.

(c) Furthermore, the Parent or the Issuer shall post in the Investor Relations section of the Parent’s website (in an area that identifies the Issuer) the unaudited quarterly and annual financial statements (including a balance sheet, income statement and statement of cash flows) of the Issuer and any Issuer Subsidiary Guarantors, which financial statements shall be posted within five Business Days of the filing of the Parent’s Form 6-K or Form 20-F (or successor form), as applicable, with the SEC containing the Parent’s consolidated financial statements for such quarter or fiscal year.

(d) In addition, the Parent shall electronically file or furnish, as the case may be, a copy of all such information and reports referred to in clauses (1) through (3) in paragraph (a) above with the SEC for public availability within the time periods specified therein at any time

the Parent is then subject to Section 13(a) or 15(d) of the Exchange Act and make such information available to the Holders, and if the Notes are represented by one or more Global Notes, the beneficial owners, of the Notes and prospective investors upon request.

(e) The Parent shall be deemed to have furnished such reports referred to in paragraph (a) above to the Trustee and the Holders if the Parent has filed such reports with the SEC via the EDGAR filing system and such reports are publicly available. If, notwithstanding the foregoing, the SEC will not accept the Parent’s filings for any reason, the Parent will post the reports referred to in paragraph (a) above on its website within the time periods that would apply to non-accelerated filers if the Parent were required to file those reports with the SEC.

(f) The Parent agrees that, for so long as any Notes remain outstanding, it will hold and participate in quarterly conference calls with the Holders and securities analysts relating to the financial condition and results of operations of the Parent and the Restricted Subsidiaries.

(g) In addition, for so long as any Notes remain outstanding and are subject to restrictions on transfer by non-Affiliates under U.S. federal securities laws, the Parent will furnish to the Holders and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the U.S. Securities Act.

Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Parent’s and the Issuer’s compliance with the covenants hereunder (as to which the Trustee is entitled to conclusively rely exclusively on an Officers’ Certificate).

(a) The Parent shall deliver to the Trustee, within 120 days after the end of each fiscal year ending after the Issue Date, an Officers’ Certificate stating (i) that a review of the activities of the Parent and the Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Parent and the Issuer have kept, observed, performed and fulfilled their obligations under this Indenture and the other Note Documents, and further stating, as to each such Officer signing such certificate, that, to the best of his or her knowledge, the Parent and the Issuer have kept, observed, performed and fulfilled each and every covenant contained in this Indenture and the other Note Documents applicable to them and are not in default in the performance or observance of any of the terms, provisions and conditions thereof (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Parent and/or the Issuer, as applicable, is taking or proposes to take with respect thereto) and (ii) either (x) that all action has been taken with respect to the recording, filing, re-recording and refiling of this Indenture and all amendments, supplemental indentures, financing statements, continuation statements and other documents, as are necessary to maintain the perfected Liens created under the Collateral Agreements under applicable law and reciting the details of such action or referring to prior Officers’ Certificates in which such details are given or (y) that no such action is necessary to maintain such Liens.

(b) The Parent shall, so long as any of the Notes are outstanding, deliver to the Trustee, within 10 Business Days of any of its Officers or any of the Issuer’s Officers becoming aware of any Default or Event of Default, a written statement specifying such Default or Event of Default and what action the Parent and/or the Issuer, as applicable, is taking or proposes to take with respect thereto.

The Parent shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders.

Each of the Issuer and the Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and each of the Issuer and the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

(a) The Parent will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly:

(1) declare or pay any dividend or make any other payment or distribution on account of Equity Interests of the Parent or any Restricted Subsidiary (including, without limitation, any payment in connection with any merger, consolidation or amalgamation involving the Parent or any of the Restricted Subsidiaries) or to the direct or indirect holders of the Parent’s or any of the Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Parent and other than dividends or distributions payable to the Parent, the Issuer or any other Restricted Subsidiary);

(2) purchase, repurchase, redeem, retire or otherwise acquire for value (including, without limitation, in connection with any merger, consolidation or amalgamation involving the Parent) any Equity Interests of the Parent held by any Person (other than any such Equity Interests held by the Parent or any Restricted Subsidiary) or any Equity Interests of any Restricted Subsidiary held by an affiliate of the Parent (other than Equity Interests held by the Parent or any Restricted Subsidiary) (in each case other than in exchange for Equity Interests of the Parent that do not constitute Disqualified Stock);

(3) make any principal payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness of the Issuer or any Guarantor that is contractually subordinated to the Notes or to any Note Guarantee (excluding any intercompany Indebtedness between or among the Parent and any of the Restricted Subsidiaries), except the purchase, redemption, defeasance, repurchase or other acquisition of such Indebtedness in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year after the date of purchase, repurchase, redemption, defeasance or acquisition, and the payment of principal of such Indebtedness at the Stated Maturity thereof; or

(all such payments and other actions set forth in these clauses (1) through (4) being collectively referred to as “ Restricted Payments ”), unless, at the time of and after giving effect to such Restricted Payment:

(I) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment;

(II) the Parent could Incur, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, at least $1.00 of additional Indebtedness pursuant to the Consolidated Interest Coverage Ratio test set forth in Section 4.09(a) ; and

(III) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Parent and the Restricted Subsidiaries since the Issue Date (excluding Restricted Payments permitted by clauses (2) through (10) of Section 4.07(b) ), is less than the sum, without duplication, of:

(A) 50% of the Parent’s Consolidated Net Income on a consolidated basis for the period (taken as one accounting period) beginning on the first day of the fiscal quarter during which the Issue Date occurs and ending on the last day of the Parent’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus

(B) 100% of the aggregate net cash proceeds or the Fair Market Value of assets other than cash, in each case received by the Parent or any Restricted Subsidiary from any Person other than the Parent or any of its Subsidiaries since the Issue Date as a contribution to its common equity capital or from the issue or sale of the Parent’s Equity Interests (other than Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of the Parent, in each case that have been converted into or exchanged for Equity Interests (other than Disqualified Stock) of the Parent (other than Equity Interests, Disqualified Stock or debt securities sold to a Subsidiary of the Parent); plus

(C) to the extent that any Restricted Investment that was made after the Issue Date is sold or disposed of for cash or Cash Equivalents or otherwise cancelled, liquidated or repaid for cash or Cash Equivalents, the lesser of (i) the return of capital received in cash or Cash Equivalents with respect to such Restricted Investment (less the cost of disposition, if any) and (ii) the initial amount of such Restricted Investment; plus

(D) to the extent that any Unrestricted Subsidiary designated as such after the Issue Date is redesignated as a Restricted Subsidiary, the lesser of (i) the Fair Market Value of the Restricted Investment made by the Parent or any of the Restricted Subsidiaries in such Subsidiary as of the date of such redesignation and (ii) such Fair Market Value as of the date on which such Subsidiary was originally designated as an Unrestricted Subsidiary after the Issue Date.

(1) the payment of any dividend or distribution or the consummation of any irrevocable redemption within 60 days after the date of declaration of the dividend or distribution or giving of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend, distribution or redemption payment would have complied with the provisions of this Indenture;

(2) the making of any Restricted Payment in exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of the Parent) of, Equity Interests of the Parent (other than Disqualified Stock) or from the substantially concurrent contribution of common equity capital to the Parent; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will be excluded from clause (III)(B) of Section 4.07(a) above;

(3) the repurchase, redemption, defeasance or other acquisition or retirement for value of Indebtedness of the Issuer or any Guarantor that is contractually subordinated to the Notes or to any Note Guarantee with the net cash proceeds from a substantially concurrent Incurrence of Permitted Refinancing Indebtedness;

(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 Parent to the holders of its Equity Interests on a pro rata basis or basis more favorable to the Parent or its Restricted Subsidiaries;

(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 such Equity Interests represent a portion of the exercise or conversion price thereof or the purchase, redemption or other acquisition or retirement for value of Equity Interests of the Parent or any Restricted Subsidiary of the Parent held by any current or former officers, directors or employees of the Parent or any of its Restricted Subsidiaries in connection with the exercise or vesting of any equity compensation (including, without limitation, stock options, restricted stock and phantom stock) in order to satisfy any tax withholding obligation with respect to such exercise or vesting;

(7) any purchase, redemption, defeasance or other acquisition or retirement of any Indebtedness subordinated to the Notes or the Note Guarantees from proceeds of an Asset Sale or in the event of a Change of Control, in each case only if prior to or simultaneously with such purchase, redemption, defeasance or other acquisition or retirement, the Parent or a Restricted Subsidiary has made the Asset Sale Offer or Change of Control Offer, as applicable, as provided in this Indenture and has completed the repurchase or redemption of all Notes validly tendered for payment in connection with such Asset Sale Offer or Change of Control Offer in accordance with the requirements of this Indenture;

(10) so long as no Event of Default has occurred and is continuing, any other Restricted Payment so long as the amount of such Restricted Payment, together with the aggregate amount of all other Restricted Payments made under this clause (10) since the Issue Date, does not exceed the greater of (x) $100.0 million and (y) 2.5% of Consolidated Net Tangible Assets as of the date such Restricted Payment is made.

The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Parent or any Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. 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 Parent 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 .

Section 4.08 Limitation on Dividend and Other Payment Restrictions Affecting Subsidiaries.

(1) pay dividends or make any other distributions on its Capital Stock to the Parent 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 Parent 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 Parent or any of the Restricted Subsidiaries; or

(3) sell, lease or transfer any of its properties or assets to the Parent 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 Specified 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 Project Facilities Agreement as in effect on the Issue Date;

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

(3) this Indenture, the Collateral Agreements, the Notes and the Note Guarantees;

(5) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Parent 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;

(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;

(9) Liens permitted to be Incurred under the provisions of Section 4.12 that limit the right of the debtor to dispose of the assets subject to such Liens;

(10) provisions limiting the disposition or distribution of assets or property in joint venture agreements, partnership agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements, which limitation is applicable only to the assets that are the subject of such agreements;

(11) restrictions on cash or other deposits or net worth imposed by customers or suppliers or required by insurance, surety or bonding companies, in each case, under contracts entered into in the ordinary course of business;

(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 Parent, 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 the covenant set forth under “—Incurrence of Indebtedness and Issuance of Preferred Stock”; 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 Issuer’s ability to make scheduled payments of interest and principal on the Notes when due or Parent’s ability to make payment under its Note Guarantee, as determined in good faith by the Board of Directors of Parent or a Financial Officer of the Parent or (b) restrictions therein are not materially more restrictive, taken as a whole, than those contained in (i) this Indenture, the Notes and the Note Guarantees or (ii) the Project Facilities Agreement as in effect on the Issue Date, as determined in good faith by the Board of Directors or a Financial Officer of the Parent.

Section 4.09 Limitation on Incurrence of Indebtedness and Issuance of Preferred Stock.

(a) The Parent will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “ Incur, ” “ Incurrence ,” “ Incurred ” and “ Incurring ” shall have meanings correlative to the foregoing) any Indebtedness (including Acquired Debt) or issue any Disqualified Stock, and the Parent will not permit any of the Restricted Subsidiaries to issue any shares of Preferred Stock; provided, however , that the Parent or any Specified Restricted Subsidiary may Incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and any Specified Restricted Subsidiary may issue Preferred Stock, if the Consolidated Interest Coverage Ratio for the Parent’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is Incurred or such Disqualified Stock or Preferred Stock is issued would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness, Disqualified Stock or Preferred Stock had been Incurred or issued, as the case may be, at the beginning of such four-quarter period.

(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 Parent or any Specified Restricted Subsidiary (other than the Issuer and any Issuer Subsidiary Guarantor) 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 Parent thereunder) not to exceed $150.0 million at any one time outstanding;

(2) the Incurrence by the Parent or any Specified Restricted Subsidiary (other than the Issuer and any Issuer Subsidiary Guarantor) 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 Parent or such Specified Restricted Subsidiary thereunder), not to exceed an amount equal to the sum of (i) for

each Vessel for which the Parent or a Specified Restricted Subsidiary (other than the Issuer and any Issuer Subsidiary Guarantor) 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 Parent or a Specified Restricted Subsidiary (other than the Issuer and any Issuer Subsidiary Guarantor), the greater of (x) $375.0 million and (y) 65% of the Appraised Value for such Vessel at the time any such Indebtedness is Incurred;

(3) the Incurrence by (i) the Issuer and any Guarantor of Indebtedness represented by the Notes (other than Additional Notes) and the related Note Guarantees to be issued on the Issue Date and (ii) the Parent or any Restricted Subsidiary of Existing Indebtedness;

(4) the Incurrence by the Parent or any Specified 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); provided that the Issuer and any Issuer Subsidiary Guarantor may only incur Permitted Refinancing Indebtedness in order to renew, refund, refinance, replace, defease or discharge, in whole or in part, Indebtedness with respect to which the Issuer or any Issuer Subsidiary Guarantor is an obligor;

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

(A) if the Issuer or any Guarantor is the obligor on such Indebtedness and the payee is not the Issuer 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 Issuer, or the applicable Note Guarantees, in the case of a Guarantor;

(B) if any Issuer Equity-Owning Subsidiary is the obligor on such Indebtedness and the payee is not the Issuer or a Guarantor, such Indebtedness must expressly provide that, for so long as any Notes are outstanding, no principal payments may be made thereon at any time an Event of Default has occurred and is continuing; and

(C) upon any (i) subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than Parent or a Restricted Subsidiary, or (ii) sale or other transfer of any such Indebtedness to a Person that is not Parent 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 Parent or any Specified Restricted Subsidiary of Hedging Obligations in the ordinary course of business and not for speculative purposes;

(7) the guarantee by the Parent or any Specified Restricted Subsidiary of Indebtedness of the Parent 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 Note 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 Parent or any Specified 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 Parent 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;

(10) the Incurrence by the Parent or any Specified 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 Parent or any Specified 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 Parent and the Specified Restricted Subsidiaries in connection with such disposition; and

(11) the Incurrence by the Parent or any Specified Restricted Subsidiary (other than the Issuer and any Issuer Subsidiary Guarantor) 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 Parent 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 Parent as accrued. Further, the reclassification of any lease or other liability of the Parent 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 .

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

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

(1) the Parent 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 Parent 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;

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

(2) any securities, notes or other obligations received by the Parent or any such Restricted Subsidiary from such transferee that are, within 180 days after receipt thereof, converted by the Parent 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 Parent 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 permanently purchase, repay or prepay secured Indebtedness of the Parent, the Issuer or any Issuer Subsidiary 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 Note Guarantees, whether or not secured (including, without limitation, redemptions or other purchases of Notes)) of the Parent or any Restricted Subsidiary (and, 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 Parent 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, Vessels, related assets and any related Ready for Sea Costs) for the Parent 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 Parent or the applicable Restricted Subsidiary to apply Net Proceeds from an Asset Sale (other than of Collateral) 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 Drilling Unit 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 Issuer 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 Notes on a first-priority secured basis (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 Parent or the applicable Restricted Subsidiary may apply the Net Proceeds to temporarily reduce outstanding revolving credit Indebtedness of the Parent 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, Issuer will, within 10 Business Days thereof, make an offer (an

“ Asset Sale Offer ”) to all Holders in accordance with Section 3.09 and the Parent will, or will cause the applicable Restricted Subsidiary to, make an Asset Sale Offer to all holders of unsubordinated Indebtedness of the Parent 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, as Asset Sale Offer will be made solely to all Holders. 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 Parent and the Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture and the Collateral Agreements. If the aggregate principal amount of Notes and, in the case of Excess Proceeds received in respect of assets not constituting Collateral, such unsubordinated Indebtedness tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select 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 $200,000 and integral multiples of $1,000 in excess thereof will be outstanding after such purchase) and, if applicable, the Issuer will select such unsubordinated 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 Issuer 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 Issuer 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 Parent 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 Parent 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 Parent or the relevant Restricted Subsidiary than those that could have been obtained in a comparable arm’s-length transaction by the Parent or such Restricted Subsidiary with a Person that is not an Affiliate of the Parent and any Restricted Subsidiary or (b) if in the good faith judgment of the Parent’s Board of Directors, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Parent or the relevant Restricted Subsidiary from a financial point of view; and

(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 Parent 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 Parent; 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 Parent 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 Parent 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 Parent or the relevant Restricted Subsidiary than those that could have been obtained in a comparable arm’s-length transaction by the Parent or such Restricted Subsidiary with a Person that is not an Affiliate of the Parent and any Restricted Subsidiary.

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 Parent.

(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 Parent 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 Parent or any Restricted Subsidiary;

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

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

(5) loans or advances to employees of the Parent 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 Parent solely because the Parent 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 ;

(8) transactions between the Parent 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 Parent or such Restricted Subsidiary, as applicable; provided that such director abstains from voting as a director of the Parent 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 Parent 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 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, the Issuer acquires or creates any Subsidiary that holds the Drilling Unit or any Related Assets or is party to a Drilling Contract or any existing Subsidiary of the Issuer that is not already a Guarantor holds the Drilling Unit or any Related Assets or becomes party to a Drilling Contract, then the Issuer will cause such Subsidiary to, within 20 Relevant Business Days of such event, (1) execute and deliver to the Trustee a supplemental indenture pursuant to which such Subsidiary will become a Guarantor, (2) 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 itself, the Trustee and the Holders, and become a Collateral Grantor thereunder, and cause such Liens to be perfected as required thereby, and (3) deliver to the Trustee one or more Officers’ Certificates and Opinions of Counsel in connection therewith as specified in this Indenture.

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

(a) If a Change of Control occurs, the Issuer will make an offer (a “ Change of Control Offer ”) to each Holder to repurchase all or any part (equal to a minimum amount of $200,000 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 Issuer 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;

(4) that, unless the Issuer 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 Issuer 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 $200,000 in principal amount or an integral multiple of $1,000 in excess thereof.

The Issuer 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 of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.15 , the Issuer 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 Issuer 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 Issuer.

(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 $200,000 or an integral multiple of $1,000 in excess thereof. The Issuer 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 Issuer 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 Issuer 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 Parent 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 Note 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.

(a) The Board of Directors of the Parent may designate any Restricted Subsidiary (other than the Issuer, any Issuer Equity-Owning Subsidiary and any Subsidiary that holds an interest in the Drilling Unit or any Related Assets or is party to any Drilling Contract (other than a Local Content Subsidiary)) to be an Unrestricted Subsidiary if:

(1) the Parent 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 Parent 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 Parent delivers to the Trustee a certified copy of a resolution of the Board of Directors of Parent 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 Parent 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 Parent.

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 Parent or the applicable Restricted Subsidiary will be in default of such covenant.

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

(1) the Parent 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;

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

(3) the Parent delivers to the Trustee a certified copy of a resolution of the Board of Directors of the Parent 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 Parent 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 Parent and the Restricted Subsidiaries taken as a whole.

(a) In the event that the Issuer receives a refund of any installment payments made by the Issuer or on its behalf under the Samsung Construction Contract or receives any amounts pursuant to any Refund Guarantee (a “ Refund ”), the Issuer will, within 20 Business Days thereof, make an offer (a “ Refund Offer ”) to all Holders to purchase the maximum principal amount of Notes that may be purchased out of the Refund at a purchase price in cash equal to 100% of the principal amount, plus accrued and unpaid interest and Additional Amounts, if any, on the Notes repurchased to the date of purchase (the “ Refund Offer Settlement Date ”), subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date.

(b) Any Refund 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 “ Refund Offer Period ”). No later than five Business Days after the termination of the Refund Offer Period, the Issuer shall apply the Refund to the purchase of the Notes or, if less than the Refund Offer Amount has been validly tendered (and not validly withdrawn), all Notes validly tendered (and not validly withdrawn) in response to the Refund Offer.

(c) Upon the commencement of a Refund Offer, the Issuer shall send, by first class mail, a notice to each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Refund Offer. The Refund Offer shall be made to all Holders. The notice, which shall govern the terms of the Refund Offer, shall state:

(i) that a Refund has been received, that a Refund Offer is being made pursuant to this Section 4.19 and the length of time the Refund Offer will remain open, including the time and date the Refund Offer will terminate (the “ Refund Offer Termination Date ”);

(ii) the amount of the Refund, the purchase price and the Refund Offer Settlement Date;

(iii) that any Note not properly tendered or accepted for payments will continue to accrue interest;

(iv) that, unless the Issuer defaults in the making such payment, any Note accepted for payment pursuant to the Refund Offer shall cease to accrue interest on and after the Refund Offer Settlement Date;

(v) that Holders electing to have any Notes purchased pursuant to a Refund Offer will be required to surrender the Note, 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 Issuer may reasonably request, to the Paying Agent at the address specified in the notice, before the Refund Offer Termination Date;

(vi) that Holders will be entitled to withdraw their election if the Paying Agent receives, prior to the Refund Offer Termination Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase, and a statement that such Holder is withdrawing its election to have such Note purchased;

(vii) that, if the aggregate principal amount of Notes surrendered by Holders exceeds the amount of the Refund, the Trustee shall select the Notes to be purchased 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 $200,000 and integral multiples of $1,000 in excess thereof will be outstanding after such purchase); and

(viii) 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.

(d) If any amount of a Refund remains after consummation of a Refund Offer, the Parent and the Restricted Subsidiaries may use such amounts for any purpose not otherwise prohibited by this Indenture and the Collateral Agreements. If the aggregate principal amount of Notes tendered in such Refund Offer exceeds the amount of the Refund, the Trustee will select 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 $200,000 and integral multiples of $1,000 in excess thereof will be outstanding after such repurchase).

(e) On or before the Refund Offer Settlement Date, the Issuer shall, to the extent lawful:

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

(2) deposit with the Paying Agent an amount equal to the purchase price in respect of all Notes or portions Notes properly tendered and not withdrawn.

(f) The Paying Agent shall mail to each Holder of Notes properly tendered and not withdrawn an amount equal to the purchase price 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. The Issuer will publicly announce the results of the Refund Offer on or as soon as practicable after the Refund Offer Settlement Date.

(g) The Issuer 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 a Refund Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.19 , the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.19 by virtue of such compliance.

(a) The Parent will not, and will not permit any of its Subsidiaries (other than the Issuer or any Issuer Subsidiary Guarantor) to, be or become party to the Drilling Contract (including as a charterer of the Drilling Unit) or otherwise hold the right to directly receive any Earnings or any other Related Assets; provided, that a Local Content Subsidiary may be a party to a Drilling Contract or otherwise hold the right to receive Earnings or to any Related Assets 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 such Related Assets. The Issuer shall, or shall cause an Issuer Subsidiary Guarantor to, at all times maintain the Earnings Account, and the Earnings Account shall at all times be in the name of the Issuer or an Issuer Subsidiary Guarantor.

(b) The Parent and the Issuer will at all times cause all such Earnings from the Drilling Contracts to be deposited into or forwarded to the Earnings Account.

Notwithstanding anything to the contrary contained herein, the Parent will not, and will not permit any of its Subsidiaries (other than the Issuer or any Issuer Subsidiary Guarantor) to, own the Drilling Unit or any right in or to the Drilling Unit. In addition, the Issuer will not, and will not permit any Issuer Subsidiary Guarantor to, sell, transfer, lease, charter, convey or otherwise dispose of the Drilling Unit or any right in or to the Drilling Unit, other than

(a) pursuant to a Drilling Contract ( provided that, prior to payment of the Notes in full, title to the Drilling Unit does not pass to the counterparty to such Drilling Contract and the Lien securing the Notes Obligations on the Drilling Unit will not be released in connection therewith), or (b) to the Issuer or any Issuer Subsidiary Guarantor.

(a) All payments made by or on behalf of the Issuer or any Guarantor under or with respect to the Notes or the Note 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 British Virgin Islands, Luxembourg or any political subdivision or any authority or agency therein or thereof having power to tax, or any other jurisdiction in which the Issuer 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 (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 Note Guarantees, the Issuer, 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 Note 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 Issuer 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 Issuer or the relevant Guarantor in order to enable the Issuer 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 Issuer 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 Issuer 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 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

(b) If the Issuer 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 Note Guarantees, the Issuer 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 Issuer or the relevant Guarantor, as applicable, will notify 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 that such payments are necessary. The Issuer 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 Issuer 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 Issuer 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.

(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 Note 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 Issuer 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 Note 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 Issuer or the relevant Guarantor by a Holder will be conclusive absent manifest error.

(f) The Issuer 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 Note 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 Note Guarantees, and the Issuer 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 Issuer 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 Issuer 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 Parent 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 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 Parent 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 Parent 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 Parent 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 Issuer will provide the Trustee with prompt written notice upon the commencement of a Suspension Period and of the occurrence of a Reversion Date.

(a) Within 10 Relevant Business Days after the Delivery Date, the Issuer shall, or shall cause the applicable Issuer Subsidiary Guarantor to, (a) execute and deliver to the Trustee or the Collateral Agent, as applicable, the Additional Collateral Agreements, whereby the Issuer or such Issuer Subsidiary Guarantor, as applicable, shall (i) grant a first-priority security interest (subject to Permitted Collateral Liens) to the Trustee, for the benefit of the Secured Parties, in the Drilling Unit and (ii) assign to the Collateral Agent, for the benefit of the Secured Parties, all Earnings derived from the Drilling Unit and its operations and all proceeds of hull and machinery and loss of hire insurance payable to the Issuer or any such Issuer Subsidiary

Guarantor in respect of the Drilling Unit and its operations (the Drilling Unit, the Earnings derived therefrom and such insurance proceeds, collectively, the “ After-Acquired Collateral ”) (as well as such other assets that constitute Collateral under the Additional Collateral Agreements), (b) execute and deliver such other Collateral Agreements as may be necessary or advisable in order to create and perfect security interests in such After-Acquired Collateral (as well as such other assets that constitute Collateral under the Additional Collateral Agreements) in favor of the Trustee or the Collateral Agent, as applicable, for the benefit of the Secured Parties, (c) cause its special Liberian counsel to execute and deliver to the Trustee a legal opinion substantially in the form of Exhibit F attached hereto, and (d) take or cause to be taken such other actions (including delivering properly completed Uniform Commercial Code financing statements) as may be necessary or advisable to vest in the Trustee or the Collateral Agent, as applicable, for the benefit of the Secured Parties, a first-priority perfected security interest (subject to Permitted Collateral Liens) in such After-Acquired Collateral and to have such After-Acquired Collateral added to the Collateral, and thereupon all provisions of this Indenture relating to the Collateral shall be deemed to relate to such After-Acquired Collateral to the same extent and with the same force and effect. For the avoidance of doubt, the Issuer and the Issuer Subsidiary Guarantors, as applicable, shall not be required to grant a security interest in, and the Collateral shall not include, any Excluded Property.

(b) If the Issuer fails to execute and deliver, or to cause the applicable Issuer Subsidiary Guarantor to execute and deliver, the Additional Collateral Agreements to the Trustee or the Collateral Agent, as applicable, by December 31, 2013, then until such time as the Additional Collateral Agreements are so executed and delivered in accordance with the provisions of this Section 4.24 , interest on the Notes will accrue at a rate that is 2% higher than the then-applicable interest rate on the Notes. All references in this Indenture and the Notes to “interest” shall be deemed to include any such additional interest to the extent it is then required to be paid.

(a) insure and keep the Drilling Unit insured or cause or procure the Drilling Unit to be insured and to be kept insured at no expense to the Trustee or the Collateral Agent in regard to (collectively, the “ Insurances ”):

provided that the Parent and the Issuer shall not be required to procure or maintain any insurance otherwise required to be procured or maintained under this clause (a), if such insurance is not commercially available in the commercial insurance market.

(c) renew or replace all such Insurances or cause or procure the same to be renewed or replaced before the relevant policies or contracts expire and to procure that the Insurers shall promptly confirm in writing to the Trustee, upon its request, as and when each such renewal or replacement is effected;

(d) duly and punctually pay, or cause duly and punctually to be paid, all premiums, calls, contributions or other sums payable in respect of all such Insurances, to produce or to cause to be produced all relevant receipts when so required by the Trustee and duly and punctually to perform and observe or to cause duly and punctually to be performed and observed any other obligations and conditions under all such Insurances;

(e) procure that all policies, binders, cover notes or other instruments of the Insurances referred to in clauses (i), (ii) and (v) of clause (a) above shall be taken out in the name of the Parent or the Issuer or any Issuer Subsidiary Guarantor or a Restricted Subsidiary, with the Trustee and the Collateral Agent as an additional insured (without liability for premiums), as their respective interests may appear, and shall incorporate a loss payable clause naming the Collateral Agent as loss payee prepared in compliance with the terms of the Insurances Assignment;

(f) procure that, upon request of the Trustee, originals or copies of all such instruments of Insurances shall be from time to time delivered to the Trustee after receipt by the Parent or the Issuer thereof;

(g) not employ the Drilling Unit or suffer the Drilling Unit to be employed otherwise than in conformity with the terms of all policies, bindings, cover notes or other instruments of the Insurances (including any warranties express or implied therein) without first obtaining the written consent of the Insurers to such employment (if required by such Insurers) and complying with such requirements as to extra premiums or otherwise as the Insurers may prescribe;

(h) cause any proceeds in respect of the Insurances referred to in paragraph (a) above (except clauses (iii), (iv) and, as applicable, (vi) of such paragraph) to be paid to the Issuer or any Issuer Subsidiary Guarantor that then owns the Drilling Unit (subject to provisions as to named insureds, additional insureds and loss payees in favor of the Trustee and/or the Collateral Agent as required by this Section 4.25 );

(i) upon the request of the Trustee, do all things necessary, proper and desirable, and execute and deliver all documents and instruments, to enable the Trustee and/or the Collateral Agent, as applicable, to collect or recover any moneys to become due in respect of the Insurances.

The Issuer shall, and the Parent or the Issuer, as applicable, shall cause each other Collateral Grantor to, at the Issuer’s sole cost and expense:

(a) at the request of the Collateral Agent, acting at the direction of the Trustee, 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

(b) at the request of the Collateral Agent, acting at the direction of the Trustee, 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.

(a) The Issuer shall not, and neither the Parent nor the Issuer, as applicable, shall permit any other 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 or (ii) otherwise as may be permitted or required by this Indenture 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 the Notes prior to or instead of such other Indebtedness.

(b) The Issuer shall not, and neither the Parent nor the Issuer, as applicable, shall permit any other Collateral Grantor to, (1) prior to December 31, 2013, enter into any amendment, supplement or modification to, or other agreement in respect of, the Samsung Construction Contract to the extent that any such amendment, supplement or modification or other agreement would have the effect of extending the Delivery Date beyond December 31, 2013 or (b) on or after December 31, 2013, enter into any amendment, supplement or modification to, or other agreement in respect of, the Samsung Construction Contract at any time when there is a default in payment of interest on the Notes.

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 Parent or the Issuer in accordance with Section 5.01 in which the Parent or the Issuer, as the case may be, is not the surviving entity, the Successor Parent or the Successor Issuer, as the case may be, 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 “Parent” shall refer instead to the Successor Parent and not to the Parent and the provisions of this Indenture referring to the “Issuer” shall refer instead to the Successor Issuer and not to the Issuer), and may exercise every right and power of, the Parent or the Issuer, as the case may be, under this Indenture with the same effect as if the Successor Parent or the Successor Issuer, as the case may be, had been named as the Parent or the Issuer, as the case may be, in this Indenture, and thereafter, the Parent or the Issuer, as the case may be, will be relieved of all obligations and covenants under this Indenture, the Notes and the Collateral Agreements.

(a) default in any payment of interest or any Additional Amounts with respect to the Notes when due, which default continues for 30 days;

(1) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “ Payment Default ”); or

(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;

(f) failure by the Parent 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;

(h) except as permitted by this Indenture or any Note Guarantee, any Note Guarantee 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, or any Person duly acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee; and

(2) appoints a Custodian (x) of the Parent, 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 substantially all of the property of the Parent, 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

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

If any Event of Default occurs and is continuing, the Trustee, by notice to the Issuer, or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes, by notice to the Issuer 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 Issuer 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.

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.

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 Issuer 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 Issuer (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.

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

(a) First : to the Trustee and the Collateral Agent, and their respective 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 or the Collateral Agent and costs and expenses of collection incurred by the Trustee or the Collateral Agent;

(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

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, and the Collateral Agent shall (subject to Section 11.06 ) comply with any such direction.

(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.

(i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

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

(i) this paragraph does not limit the effect of paragraph (b) of this Section 7.01 ;

(ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

(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 Issuer. 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.

(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 Parent or the Issuer shall be sufficient if signed by an Officer of the Parent or the Issuer, respectively.

(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 Issuer 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.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer, 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 Issuer’s use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’s or the Parent’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 Issuer shall pay to the Trustee from time to time such reasonable compensation as the Issuer 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 Issuer 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 Issuer 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 this Indenture against the Issuer and the Guarantors (including this Section 7.06 ) and defending itself against any claim (whether asserted by the Issuer, 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, bad faith or willful misconduct. The Trustee shall notify the Issuer and the Guarantors promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer and the Guarantors shall not relieve the Issuer or the Guarantors of their obligations hereunder. The Issuer and the Guarantors shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Issuer and the Guarantors shall pay the reasonable fees and expenses of such counsel. Neither the Issuer nor any Guarantor need pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

The obligations of the Issuer 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 Issuer’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 Issuer’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 Issuer. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing and may appoint a successor trustee with the consent of the Issuer. The Issuer may remove the Trustee if:

(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;

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer 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 Issuer.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer 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 Issuer, 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 Issuer. 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 Issuer’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 Issuer 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.

The Issuer 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 Issuer’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 Issuer shall be deemed to have discharged its obligations with respect to all outstanding Notes and the Collateral Agreements to which it is a party, each Guarantor shall be deemed to have discharged its obligations with respect to its Note Guarantee and 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 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 Issuer 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 Note 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 Note Guarantees and this Indenture, and the Issuer and the other Collateral Grantors shall be deemed to have satisfied all of their obligations under the Collateral Agreements (and the Trustee, on demand of and at the expense of the Issuer, 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 Issuer’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 and immunities of the Trustee and the Agents, and the Issuer’s and the Guarantors’ obligations in connection therewith; and

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

Upon the Issuer’s exercise under Section 8.01 of the option applicable to this Section 8.03 , the Issuer 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 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 Note Guarantees, the Issuer 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 Issuer’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.

(a) the Issuer 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 Issuer 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 Issuer 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 Issuer 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,

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 Issuer 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 Parent or any of its Restricted Subsidiaries is a party or by which the Issuer or any of its Restricted Subsidiaries is bound;

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

(g) the Issuer 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.

Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

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 Parent 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.

The Issuer 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 Issuer from time to time upon the written request of the Issuer 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 Issuer, 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 Issuer on its written request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter be permitted to look only to the Issuer 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 Issuer 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 Issuer 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 Issuer.

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 Issuer’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 Issuer 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 Issuer or such Guarantor, as 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 Note Guarantees and 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 Issuer’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 Issuer’s obligations in connection therewith), and the Trustee, at the expense of the Issuer, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture with respect to all the Notes, when:

(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 Issuer, 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 Issuer 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 Issuer or any Guarantor is a party or by which the Issuer 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);

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

(4) the Parent or the Issuer 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 Parent 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.

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

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

(c) to provide for the assumption of the Issuer’s or a Guarantor’s obligations to the Holders in the case of a merger or consolidation or sale of all or substantially all of the Issuer’s or such Guarantor’s assets, as applicable;

(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 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 Notes 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 and the Collateral Agreements of a successor Trustee or Collateral Agent;

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

(h) to release Collateral or any Note Guarantee when permitted or required by this Indenture or the Collateral Agreements;

(i) to allow any Guarantor to execute a supplemental indenture and/or a Note 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;

(k) to enter into any and all Collateral Agreements and the transactions contemplated thereby respecting the registration and mortgaging of the Drilling Unit and to perfect the security interests and Liens granted therein;

(l) to accept and consent to, and to take, any and all steps to perfect a security interest in the Drilling Unit, Drilling Contracts and other Collateral granted pursuant to the Collateral Agreements; or

(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.

Upon the request of the Issuer, and upon receipt by the Trustee of the documents described in Section 9.06 , the Trustee and the Collateral Agent shall join with the Issuer 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 neither the Trustee nor the Collateral Agent shall 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 Issuer, 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 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). 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;

(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);

(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 , 4.15 or 4.19 );

(i) release any Guarantor from any of its obligations under its Note 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 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 all or substantially all of the Collateral.

Upon the request of the Issuer 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 and/or the Collateral Agent, as applicable, shall join with the Issuer and the Guarantors in the execution of such amendment, supplement or waiver, unless such amendment, supplement or waiver affects the Trustee’s or the Collateral Agent’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee or the Collateral Agent, as the case may be, 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 Issuer shall mail to the Holders a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer 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 Issuer 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 .

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 Issuer, 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 and the Collateral Agent 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 their respective 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 and/or the Collateral Agent, the Trustee and/or the Collateral Agent, as the case may be, may, but need not, sign such amendment, supplemental indenture or grant such waiver. In executing any such amendment, supplemental indenture or waiver, the Trustee and the Collateral Agent 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 Issuer. 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 Issuer, 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 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 Issuer 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.

(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.

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, the Collateral Agent and their respective successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the Obligations of the Issuer 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 Issuer to the Holders, the Trustee or the Collateral Agent 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.

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 Issuer 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 Issuer, 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 Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenants that its Note 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 Issuer, the Guarantors, or any Custodian, trustee or other similar official acting in relation to any of the Issuer or the Guarantors, any amount paid by the Issuer or any Guarantor to the Trustee or such Holder, the Note 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 Note 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 Note 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 Note Guarantees.

The Note Guarantee of a Guarantor (other than the Parent) 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 Parent or a Restricted Subsidiary, if the sale or other disposition is conducted in accordance with Sections 4.10 and 5.01(c) , as applicable, and complies with the Collateral Agreements to the extent 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 Parent, if the sale or other disposition is conducted in accordance with Sections 4.10 and 5.01(c) , as applicable, and complies with the Collateral Agreements to the extent 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; 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 Issuer 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 Issuer at the Issuer’s expense in order to evidence the release of any Guarantor (other than the Parent) from its obligations under its Note Guarantee. Any Guarantor not released from its obligations under its Note 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 Note 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 Note Guarantee. The obligations of each Guarantor under its Note 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 Note Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Guarantor under its Note 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 Note 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.

The execution by each Guarantor of this Indenture (or a supplemental indenture hereto) evidences the Note 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 Note Guarantee set forth in this Indenture on behalf of each Guarantor.

Each Guarantor shall be subrogated to all rights of Holders against the Issuer 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 Issuer under this Indenture or the Notes shall have been paid in full.

In order to secure the due and punctual payment of the Secured Obligations, (i) on the Issue Date simultaneously with the execution and delivery of this Indenture, (x) the Issuer has executed and delivered the Security Agreement, the Samsung Construction Contract Assignment and a deposit account control agreement with respect to the Earnings Account and (y) Pacific Drillship (Gibraltar) Limited has executed and delivered a Pledge Agreement pursuant to which it has granted to the Collateral Agent a first-priority security interest (subject to Permitted Collateral Liens) in all of the Equity Interests of the Issuer, and (ii) after the Issue Date, in accordance with the provisions of Sections 4.13 , 4.24 and 4.26 and this Article 11 , (x) within 10 Relevant Business Days after the Delivery Date, the Issuer or the applicable Issuer Subsidiary Guarantor shall execute and deliver the Additional Collateral Agreements, (y) each Person that acquires any Equity Interests of the Issuer shall, substantially concurrently upon such Person’s acquisition of such Equity Interests, execute and deliver to the Collateral Agent a Pledge Agreement in form and substance reasonably satisfactory to the Collateral Agent (which shall be in substantially the same form as the Pledge Agreement dated as of the Issue Date or such other form as the Collateral Agent and the Issuer may reasonably agree (and, if at such time, the Issuer is organized under the laws of any jurisdiction other than the British Virgin Islands, with such changes as may be appropriate given the Issuer’s jurisdiction of organization at such time)), granting a first-priority security interest (subject to Permitted Collateral Liens) in the Equity Interests of the Issuer owned by such Person and (z) 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 Collateral Grantor 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 Issuer that is not already a Collateral Grantor is required to become an Issuer Subsidiary Guarantor pursuant to Section 4.13 , then such Collateral Grantor 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 an Issuer Subsidiary 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 Collateral Grantor or such other Subsidiary which are required to, but do not already, constitute Collateral. In each case described above, each Collateral Grantor 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, including, without limitation, entering into Foreign Security Documents (as defined in the Security Agreement). For the avoidance of doubt, the Collateral Grantors shall not be required to grant a security interest in, and the Collateral shall not include, any Excluded Property, the Collateral Grantors shall not be required to execute an assignment of any Drilling Contract, and in no event shall the Parent, the Issuer and the Issuer Subsidiary Guarantors 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.

(2) in part, with respect to any asset constituting Collateral (other than any Equity Interests of the Issuer), if such asset is sold or otherwise disposed of to a Person that is not (either before or after giving effect to such transaction) the Parent or a Restricted Subsidiary in a transaction that is not prohibited by this Indenture, subject to compliance with Section 4.10 and the Collateral Agreements (other than the provisions thereof relating to the future use of the proceeds of such sale or other disposition), and the Issuer has delivered to the Collateral Agent and the Trustee an Officers’ Certificate and Opinion of Counsel (with customary assumptions and qualifications for such types of opinion) certifying to such effect; provided that (i) pending its application or use in compliance with Section 4.10 , any cash received from a disposition of Collateral shall be deposited in a deposit account controlled by the Collateral Agent and held as Collateral and, from such deposit account, the applicable Collateral Grantor may withdraw funds to deploy the proceeds of an Asset Sale in compliance with Section 4.10 , and (ii) to the extent that any Collateral is sold or otherwise disposed of in accordance with the terms of Section 4.10 , the non-cash consideration received shall be pledged as Collateral under the Collateral Agreements contemporaneously with such sale, in accordance with the requirements of this Indenture and the Collateral Agreements;

Section 11.05 Possession and Use of Collateral; No Impairment of the Security Interests .

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

(b) The Issuer shall not, and neither the Parent nor the Issuer, as applicable, shall permit any other Collateral Grantor to, take any action, or knowingly omit to take any action, which action or omission would have the result of materially impairing the validity, perfection or priority of the security interests in the Collateral created by the Collateral Agreements, except as expressly set forth in this Indenture or the Collateral Agreements (including any action that would result in a Permitted Collateral Lien).

(c) Neither the Issuer nor any Guarantor will take any action or otherwise attempt to enforce any claim or maritime lien held by it against the Drilling Unit that has priority over any claim or Lien of the Collateral Agent or the Trustee in respect of the Drilling Unit, including any claims or Liens arising under the Vessel Mortgage.

(d) Subject to any conditions in the Collateral Agreements, upon the occurrence and during the continuance of an Event of Default, at the election of the Collateral Agent, as directed by the Trustee, acting at the direction of the Holders of a majority in aggregate principal amount of Notes then outstanding:

(1) all rights of each Collateral Grantor to exercise such voting or other consensual rights pertaining to its Collateral will cease, and all such rights will become vested in the Collateral Agent, which, to the extent permitted by law, will have the sole right to exercise such voting and other consensual rights in accordance with the Collateral Agreements;

(2) all rights of each Collateral Grantor to receive all cash dividends, principal, interest and other payments made upon or with respect to its Collateral will cease and such cash dividends, principal, interest and other payments will be paid to the Collateral Agent in accordance with the terms of the Collateral Agreements; and

(3) the Collateral Agent may sell the Collateral or any part of the Collateral in accordance with the terms of the Collateral Agreements.

The Collateral Agent, at the direction of the Trustee, acting at the direction of the Holders of a majority in aggregate principal amount of the Notes outstanding, will be permitted to release all or any portion of the Collateral from the Liens created by the Collateral Agreements and foreclose on the Collateral following an Event of Default.

(a) The Trustee and each of the Holders by acceptance of the Notes hereby acknowledge the Issuer’s appointment of the Collateral Agent as the Trustee’s and the Holders’ collateral agent under this Indenture and the Collateral Agreements, and the Trustee and each of the Holders by acceptance of the Notes hereby irrevocably authorize the Collateral Agent to take such action on their behalf under the provisions of this Indenture and the Collateral Agreements and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture and the Collateral Agreements, together with such powers as are reasonably incidental thereto. The Collateral Agent agrees to act as such on the express conditions contained in this Section 11.06 . The provisions of this Section 11.06 are solely for the benefit of the Collateral Agent and none of the Trustee, any of the Holders, the Issuer or any of the other Collateral Grantors shall have any rights as a third party beneficiary of any of the provisions contained herein. Notwithstanding any provision to the contrary contained elsewhere in this Indenture and the Collateral Agreements, the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the Collateral Agreements, nor shall the Collateral Agent have or be deemed to have any fiduciary relationship with the Trustee, any Holder or the Issuer or any other Collateral Grantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture and the Collateral Agreements or otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent shall not be construed to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

(b) The Collateral Agent may execute any of its duties under this Indenture and the Collateral Agreements by or through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties, and the written advice of such 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. The Collateral Agent shall not be responsible for the negligence or misconduct of any agent, employee or attorney-in-fact that it selects as long as such selection was made without negligence or willful misconduct.

(c) None of the Collateral Agent or any of its agents or employees shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Indenture or the transactions contemplated hereby (except for its own gross negligence, bad faith or willful misconduct) or under or in connection with any Collateral Agreements or the transactions contemplated thereby (except for its own gross negligence, bad faith or willful misconduct), or (ii) be responsible in any manner to the Trustee or any Holder for any recital, statement, representation, warranty, covenant or agreement made by the Issuer or any other Collateral Grantor contained in this Indenture or any of the Collateral Agreements, or in any certificate, report, statement or other document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Indenture or any of the Collateral Agreements, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Indenture or any of the Collateral Agreements, or for any failure of the Issuer or any other Collateral Grantor or any other party to this Indenture or any of the Collateral Agreements to perform its obligations hereunder or thereunder. None of the Collateral Agent or any of its agents or employees shall be under any obligation to the Trustee or any Holder to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Indenture or any of the Collateral Agreements or to inspect the properties, books or records of the Issuer or any other Collateral Grantor.

(d) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless the Collateral Agent shall have received written notice from the Trustee or the Issuer referring to this Indenture, describing such Default or Event of Default and stating that such notice is a “notice of default.” The Collateral Agent shall take such action with respect to such Default or Event of Default as may be requested by the Trustee acting in accordance with Article 6 (subject to this Section 11.06 ); provided , however , that unless and until the Collateral Agent has received any such request, the Collateral Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable.

(e) The Collateral Agent may resign at any time by so notifying the Issuer and the Trustee in writing at least thirty (30) days prior to the proposed date of resignation, such resignation to be effective upon the acceptance of a successor agent to its appointment as Collateral Agent. If the Collateral Agent resigns under this Indenture, the Trustee, subject to the consent of the Issuer (which shall not be unreasonably withheld and which shall not be required during a continuing Event of Default), shall appoint a successor Collateral Agent. If no successor collateral agent is appointed prior to the intended effective date of the resignation of the Collateral Agent (as stated in the notice of resignation), the Collateral Agent may appoint, after consulting with the Trustee, subject to the consent of the Issuer (which shall not be unreasonably withheld and which shall not be required during a continuing Event of Default), a successor Collateral Agent, which may be the same Person as the Trustee. If no successor Collateral Agent is appointed and consented to by the Issuer pursuant to the preceding sentence within thirty (30) days after the intended effective date of resignation (as stated in the notice of resignation), the Collateral Agent, the Issuer or the Holders of at least 10% in principal amount of the then outstanding principal amount of the Notes shall be entitled to petition at the expense of the Issuer a court of competent jurisdiction to appoint a successor Collateral Agent. A successor Collateral Agent shall deliver a written acceptance of its appointment to the retiring Collateral Agent and to the Issuer. Thereupon, the resignation of the retiring Collateral Agent

shall become effective, and the successor Collateral Agent shall have all the rights, powers and the duties of the Collateral Agent under this Indenture and the Collateral Agreements. The successor Collateral Agent shall mail a notice of its succession to the Trustee. The retiring Collateral Agent shall promptly transfer all property held by it as Collateral Agent to the successor Collateral Agent, provided that all sums owing to the retiring Collateral Agent hereunder have been paid. Notwithstanding the replacement of the Collateral Agent pursuant to this Section 11.06(e) , the Issuer’s obligations under this Section 11.06 and Section 11.11 shall continue for the benefit of the retiring Collateral Agent.

In the event that the Collateral Agent is required to acquire title to an asset for any reason, or take any operational or managerial action of any kind in regard thereto, in order to carry out any fiduciary or trust obligation for the benefit of another, which in the Collateral Agent’s sole discretion may cause the Collateral Agent to incur potential liability under CERCLA, any Environmental Law or any other federal, state or local law, the Collateral Agent reserves the right, instead of taking such action, to either resign as the Collateral Agent or arrange for the transfer of the title or control of the asset to a court-appointed receiver. The Collateral Agent shall not be liable to the Parent, the Issuer, the Holders of Notes, or any other Person for any Environmental Claims or any liability arising under CERCLA, any Environmental Law, or under any federal, state or local law, rule or regulation by reason of the Collateral Agent’s actions and conduct as authorized, empowered and directed hereunder or relating to the presence, release or threatened release of Hazardous Materials.

(f) Except as otherwise explicitly provided herein or in the Collateral Agreements, neither the Collateral Agent nor any of its officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither the Collateral Agent nor any of its officers, directors, employees or agents shall be responsible for any act or failure to act hereunder, except for its own willful misconduct, gross negligence or bad faith.

(g) The Trustee is authorized and directed by the Holders and the Holders by acquiring the Notes are deemed to have authorized the Trustee, as applicable, to (i) enter into the Collateral Agreements to which it is a party, (ii) bind the Holders on the terms as set forth in such Collateral Agreements, (iii) perform and observe its obligations and exercise its rights and powers under such Collateral Agreements, including entering into amendments permitted by the terms of this Indenture or the Collateral Agreements and (iv) cause the Collateral Agent to enter into and perform its obligations under the Collateral Agreements. The Collateral Agent is authorized and directed by the Trustee and the Holders and the Holders by acquiring the Notes are deemed to have authorized the Collateral Agent, to (i) enter into the Collateral Agreements to which it is a party, (ii) bind the Trustee and the Holders on the terms as set forth in such Collateral Agreements and (iii) perform and observe its obligations and exercise its rights and powers under such Collateral Agreements, including entering into amendments permitted by the terms of this Indenture or the Collateral Agreements. Each Holder, by its acceptance of a Note, is deemed to have consented and agreed to the terms of each Collateral Agreement, as originally in effect and as amended, restated, replaced, supplemented or modified from time to time in accordance with its terms or the terms of this Indenture.

(h) The Collateral Agent shall have no obligation whatsoever to the Trustee or any of the Holders to assure that the Collateral exists or is owned by the Issuer or any of the other Collateral Grantors or is cared for, protected or insured or has been encumbered, or that the Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Collateral Grantor’s property constituting Collateral intended to be subject to the Lien and security interest of the Collateral Agreements has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto.

(i) The Collateral Agent (i) shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within its rights or powers, or for any error of judgment made in good faith by an authorized officer, unless it is proved that the Collateral Agent was negligent in ascertaining the pertinent facts, (ii) shall not be liable for interest on any money received by it except as the Collateral Agent may agree in writing with the Issuer (and money held in trust by the Collateral Agent need not be segregated from other funds except to the extent required by law), and (iii) may consult with counsel of its selection and the written advice or opinion of such 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. The grant of permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act. For the avoidance of doubt, nothing herein shall require the Collateral Agent to file financing statements or continuation statements, or be responsible for maintaining the security interests purported to be created by the Collateral Agreements (except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it under this Indenture or any Collateral Agreement) and such responsibility shall be solely that of the Issuer.

Notwithstanding anything else to the contrary herein, the Collateral Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers required in writing by the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (or such other number or percentage of the aggregate principal amount of Notes as shall be necessary under the circumstances as provided in the Indenture). Whenever reference is made in any Collateral Agreements to any discretionary action by, consent, designation, specification, requirement or approval of, notice, request or other communication from, or other direction given or action to be undertaken or to be (or not to be) suffered or omitted by the Collateral Agent or to any election, decision, opinion, acceptance, use of judgment, expression of satisfaction or other exercise of discretion, rights or remedies to be made (or not to be made) by the Collateral Agent, it is understood that in all cases the Collateral Agent shall have no duty and shall be fully justified in failing or refusing to take any such action under unless it shall have received written instructions from the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (or such other number or percentage of the aggregate principal amount of Notes as shall be necessary under the circumstances as provided in the Indenture).

The Collateral Agent may refuse to act if in the Collateral Agent’s opinion such action (i) is contrary to law or the provisions of any Collateral Agreements; (ii) may expose the Collateral Agent to financial or personal liability (unless the Collateral Agent shall have received indemnity and security to its satisfaction for such liability); or (iii) is unduly prejudicial to Secured Parties not joining in such notice, consent, direction or instruction.

Section 11.07 Purchaser Protected . No purchaser or grantee of any property or rights purporting to be released from the Liens in favor of the Collateral Agent shall be bound to ascertain the authority of the Collateral Agent or Trustee to execute the release or to inquire as to the existence of any conditions herein prescribed for the exercise of such authority so long as the conditions set forth in Section 11.03 have been satisfied.

Section 11.08 Authorization of Actions to Be Taken by the Collateral Agent Under the Collateral Agreements . Subject to the provisions of the Collateral Agreements, (a) each of the Trustee and the Collateral Agent may, in its sole discretion and without the consent of the Holders, take all actions as it deems necessary or appropriate in order to (i) enforce any of the terms of the Collateral Agreements and (ii) collect and receive any and all amounts payable in respect of the Secured Obligations and (b) each of the Trustee and the Collateral Agent shall have power to institute and to maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Collateral by any act that may be unlawful or in violation of the Collateral Agreements or this Indenture, and such suits and proceedings as the Trustee or the Collateral Agent may deem expedient to preserve or protect its interests and the interests of the Holders in the Collateral (including the power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest thereunder or be prejudicial to the interests of the Holders, the Trustee or the Collateral Agent).

Section 11.09 Authorization of Receipt of Funds by the Trustee Under the Collateral Agreements . The Trustee is authorized to receive any funds for the benefit of Holders distributed under the Collateral Agreements and to apply such funds as provided in Section 6.10 .

Section 11.10 Powers Exercisable by Receiver or Trustee . In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 11 upon the Issuer or any other Collateral Grantor, as applicable, with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Issuer or any other Collateral Grantor, as applicable, or of any officer or officers thereof required by the provisions of this Article 11 .

Section 11.11 Compensation and Indemnification . The Collateral Agent shall be entitled to the compensation and indemnification set forth in Section 7.06 (with the references to the Trustee therein being deemed to refer to the Collateral Agent). In addition to and not withstanding any other obligation contained in this Indenture or any Collateral Agreements, the Issuer and the Guarantors agree to jointly and severally indemnify the Trustee and the Collateral Agent from and against any and all claims, demands, suits, actions, investigations, proceedings, liabilities, fines, costs, penalties, and damages, and all reasonable

and documented out of pocket fees and disbursements of attorneys in connection with or arising out of any presence or release of Hazardous Materials at, on, under, to, from or related to any Collateral or any Environmental Actions, Environmental Liabilities and costs or Remedial Actions related in any way to any such Collateral, except in each case as may be caused by the Collateral Agent’s gross negligence, bad faith or willful misconduct.

Waivers of notice by any Holder shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

Notwithstanding anything to the contrary contained herein, as long as the Notes are in the form of a Global Note, notice to the Holders thereof may be made electronically in accordance with the applicable procedures of the Depositary.

THIS NOTE HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”) OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. NEITHER THIS NOTE NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE OFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION. THE HOLDER OF THIS NOTE, BY ITS ACCEPTANCE HEREOF, AGREES ON ITS OWN BEHALF AND ON BEHALF OF ANY INVESTOR ACCOUNT FOR WHICH IT HAS PURCHASED NOTES, TO OFFER, SELL OR OTHERWISE TRANSFER SUCH NOTE, PRIOR TO THE DATE (THE “RESALE RESTRICTION TERMINATION DATE”) THAT IS, IN THE CASE OF RULE 144A NOTES: ONE YEAR AND IN THE CASE OF REGULATION S NOTES: 40 DAYS, AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF AND THE LAST DATE ON WHICH THE ISSUER OR ANY AFFILIATE OF THE ISSUER WAS THE OWNER OF SUCH NOTE (OR ANY PREDECESSOR OF SUCH NOTE), ONLY (A) TO THE ISSUER, (B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE U.S. SECURITIES ACT, (C) FOR SO LONG AS THIS NOTE IS ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE U.S. SECURITIES ACT (“RULE 144A”), TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (D) PURSUANT TO OFFERS AND SALES THAT OCCUR OUTSIDE THE UNITED STATES IN COMPLIANCE WITH REGULATION S UNDER THE U.S. SECURITIES ACT, (E) PURSUANT TO RULE 144 OF THE SECURITIES ACT OR (F) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE U.S. SECURITIES ACT, SUBJECT TO THE ISSUER’S AND THE TRUSTEE’S RIGHT PRIOR TO ANY SUCH OFFER,

SALE OR TRANSFER PURSUANT TO CLAUSE (F) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM.

IN THE CASE OF REGULATION S NOTES: BY ITS ACQUISITION HEREOF, THE HOLDER HEREOF REPRESENTS THAT IT IS NOT A U.S. PERSON NOR IS IT PURCHASING FOR THE ACCOUNT OF A U.S. PERSON AND IS ACQUIRING THIS NOTE IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH REGULATION UNDER THE U.S. SECURITIES ACT.

(ii) The Issuer, acting in its discretion, may remove the legend set forth in paragraph (i) above from any Transfer Restricted Security at any time on or after the Resale Restriction Termination Date applicable to such Transfer Restricted Security. Without limiting the generality of the preceding sentence, the Issuer may effect such removal by issuing and delivering, in exchange for such Transfer Restricted Security, an Unrestricted Initial Note without such legend, registered to the same Holder and in an equal principal amount, and upon receipt by the Trustee of a written order of the Issuer stating that the Resale Restriction Termination Date applicable to such Transfer Restricted Security has occurred and requesting the authentication and delivery of an Unrestricted Initial Note in exchange therefor (which order shall not be required to be accompanied by any Opinion of Counsel or any other document) given at least three Business Days in advance of the proposed date of exchange specified therein (which shall be no earlier than such Resale Restriction Termination Date), the Trustee shall authenticate and deliver such Unrestricted Initial Note to the Depository or pursuant to such Depository’s instructions or hold such Note as Note Custodian for the Depository and shall request the Depository to, or, if the Trustee is Note Custodian of such Transfer Restricted Security, shall itself, surrender such Transfer Restricted Security in exchange for such Unrestricted Initial Note without such legend and thereupon cancel such Transfer Restricted Security so surrendered, all as directed in such order. For purposes of determining whether the Resale Restriction Termination Date has occurred with respect to any Notes evidenced by a Transfer Restricted Security or delivering any order pursuant to this Section 2.3(b)(ii) with respect to such Notes, (i) only those Notes which a Principal Officer of the Issuer actually knows (after reasonable inquiry) to be or to have been owned by an Affiliate of the Issuer shall be deemed to be or to have been, respectively, owned by an Affiliate of the Issuer; and (ii) “Principal Officer” means the principal executive officer, the principal financial officer, the treasurer or the principal accounting officer of the Issuer.

For purposes of this Section 2.3(b)(ii), all provisions relating to the removal of the legend set forth in paragraph (i) above shall relate, if the Resale Restriction Termination Date has occurred only with respect to a portion of the Notes evidenced by a Transfer Restricted Security, to such portion of the Notes so evidenced as to which the Resale Restriction Termination Date has occurred.

Each holder of any Note evidenced by any Restricted Global Note, by its acceptance thereof, (A) authorizes and consents to, (B) appoints the Issuer as its agent for the sole purpose of delivering such electronic messages, executing and delivering such instruments and taking such other actions, on such holder’s behalf, as the Depository or the Trustee may require to effect, and (C) upon the request of the Issuer, agrees to deliver such electronic messages, execute and deliver such instruments and take such other actions as the Depository or the Trustee may require, or as shall otherwise be necessary to effect, the removal of the legend set forth in Section 2.3(b)(i) (including by means of the exchange of all or the portion of such Restricted Global Note evidencing such Note for a certificate evidencing such Note that does not bear such legend) at any time after the Resale Restriction Termination Date.

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

(c) Cancellation or Adjustment of Global Note . At such time as all beneficial interests in a Global Note have either been exchanged for certificated Notes, redeemed, purchased or canceled, such Global Note shall be returned to the Trustee for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for certificated Notes, redeemed, purchased or canceled, or if any certificated Note is exchanged for such a beneficial interest, the principal amount of Notes represented by such Global Note shall be reduced or increased, as appropriate, and an adjustment shall be made on the books and records of the Trustee (if it is then the Notes Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Notes Custodian, to reflect such reduction or increase, as the case may be.

(i) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall, upon its receipt of an authentication order from the Issuer, authenticate certificated Notes and Global Notes at the Registrar’s request.

(ii) No service charge shall be made for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax, assessments or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charge payable upon any exchange or transfer pursuant to Sections 3.06, 4.10, 4.15 and 9.05 of the Indenture).

(iii) The Registrar shall not be required to register the transfer of or exchange of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed.

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

(v) All Notes issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Notes surrendered upon such transfer or exchange. Accordingly, for purposes of clause (3) of Section 4.09(b) of this Indenture, “the Notes (other than Additional Notes) and the related Note Guarantees to be issued on the Issue Date” shall be deemed to refer to and include any Notes issued in exchange for, or upon registration of transfer of, or in lieu of, any such Notes (or any predecessor Notes thereof) pursuant to this Indenture.

(e) No Obligation of the Trustee . The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in the Depository or other Person with respect to the accuracy of the records of the Depository or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of optional redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depository or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its members, participants and any beneficial owners.

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

(a) A Global Note deposited with the Depository or with the Trustee as custodian for the Depository pursuant to Section 2.1 shall be transferred to the beneficial owners thereof in the form of certificated Notes in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, only if such transfer complies with Section 2.3 and (i) the Depository notifies the Issuer that it is unwilling or unable to continue as Depository for such Global Note or if at any time such Depository ceases to be a “clearing agency” registered under the Exchange Act and in either case the Issuer fails to appoint a successor depositary within 90 days, (ii) the Issuer, at its option, but subject to the Depository’s requirements, notifies the Trustee in writing that it elects to cause the issuance of the Certificated Notes, or (iii) an Event of Default has occurred and is continuing and the Depository notifies the Trustee of its decision to exchange the Global Notes for Certificated Notes.

(b) Any Global Note that is transferable to the beneficial owners thereof pursuant to this Section shall be surrendered by the Depository or the Notes Custodian to the Trustee located at its Corporate Trust Office to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Note, an equal aggregate principal amount of certificated Notes of authorized denominations. Any portion of a Global Note transferred pursuant to this Section shall be executed, authenticated and delivered only in denominations equal to $200,000 or an integral multiple of $1,000 in excess thereof, and registered in such names as the Depository shall direct. Any certificated Note delivered in exchange for an interest in a Global Note shall, except as otherwise provided by Section 2.3(b), bear the Restricted Notes Legend set forth in Exhibit 1 hereto.

Pacific Drilling V Limited, a British Virgin Islands company limited by shares, promises to pay to , or registered assigns, the principal sum of Dollars on December 1, 2017 [or such greater or lesser amount as may be indicated on Schedule A hereto] ¹ .

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

IN WITNESS WHEREOF, Pacific Drilling V Limited has caused this instrument to be duly executed.

Capitalized terms used herein but not defined shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

1. Interest . Pacific Drilling V Limited, a British Virgin Islands company limited by shares (the “ Issuer ”), promises to pay interest on the unpaid principal amount of this Note at 7.250% per annum. The Issuer will pay interest semi-annually in arrears on June 1 and December 1 of each year (each an “ Interest Payment Date ”), commencing June 1, 2013. In certain circumstances specified in the Indenture, the Issuer may be required to pay Additional Amounts with respect to the Notes. Whenever in this Note there is mentioned, in any context, the payment of amounts based upon the principal amount of this Note or of principal, interest or of any other amount payable under, or with respect to, this Note, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. In certain circumstances specified in the Indenture, the Issuer may be required to pay interest on the principal amount of this Note at a rate that is 2.0% higher than the then applicable interest rate on the Notes. All references in this Note to “interest” shall be deemed to include any such additional interest to the extent it is then required to be paid. If any date for payment on the Notes falls on a day that is not a Business Day, such payment may be made on the next succeeding Business Day with the same force and effect as if made on the due date, and no additional interest will accrue solely as a result of such delayed payment. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of original issuance; provided that if there is no existing Default or Event of Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date, except in the case of the original issuance of Notes, in which case interest shall accrue from the date of authentication. The Issuer shall pay (i) interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is equal to the then applicable interest rate on the Notes and (ii) interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Amounts, if any, (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment . The Issuer will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the May 15 or November 15 next preceding the Interest Payment Date, even if such Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. Holders must surrender Notes to the Paying Agent to collect payments of principal and premium, if any, together with accrued and unpaid interest and Additional Amounts, if any, due at maturity. Any Notes in certificated form will be payable as to principal, premium, if any, interest, if any, and Additional Amounts, if any, at the office or agency of the Paying Agent and Registrar maintained for such purpose within the City and State of New York, or, at the option of the Issuer, payment of interest may be made by

check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds to an account in the United States will be required with respect to any amounts due on all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Issuer or the Paying Agent. Notwithstanding the foregoing, if this Note is a Global Note, payment may be made pursuant to the applicable procedures of the Depository as permitted in the Indenture. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

Other than for purposes of effecting a redemption or an offer to purchase described in Sections 3.07, 3.08, 3.09, 4.10, 4.15 and 4.19 of the Indenture or in connection with a Legal Defeasance, Covenant Defeasance or Discharge, the Parent or any of its Subsidiaries may act in any such capacity.

4. Indenture . The Issuer issued the Notes under an Indenture dated as of November 28, 2012 (“ Indenture ”) among the Issuer, the Guarantors, the Trustee and the Collateral Agent. The Notes are subject to the terms of the Indenture, and Holders are referred to the Indenture for a statement of such terms. The Notes are senior secured obligations of the Issuer. The Issuer shall be entitled, subject to its compliance with Section 4.09 of the Indenture, to issue Additional Notes pursuant to Section 2.14 of the Indenture. In the event of a conflict between the Indenture and this Note, the terms of the Indenture shall control.

The Registrar need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuer and the Registrar need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed.

Notwithstanding the preceding,

in the case of an Event of Default arising from such events of bankruptcy, insolvency or reorganization described in Section 6.01(i) or 6.01(j) of the Indenture with respect to the Issuer or any Guarantor, all outstanding Notes shall become due and payable immediately without further action or notice. Holders may not enforce the Indenture, the Notes or the Collateral Agreements except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power conferred on it with respect to the Notes. The Trustee may withhold from Holder notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal of, or interest or premium, if any, on, the Notes. 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 the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under the Indenture, except as provided in the Indenture. The Parent is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and within 10 Business Days of any of its Officers or any of the Issuer’s Officers becoming aware of any Default or Event of Default, the Parent is required to deliver to the Trustee a statement specifying such Default or Event of Default.

14. Defeasance and Discharge . The Notes are subject to defeasance and discharge upon the terms and conditions specified in the Indenture.

15. No Recourse Against Others .

Each Holder, by accepting a Note, waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

16. Collateral Agreements . Prior to the Delivery Date (and during the period from the Delivery Date to the date when the Additional Collateral Agreements are executed and delivered to the Trustee), the obligations of the Issuer and the Guarantors under the Indenture, the Notes and the Note Guarantees will be secured by a Lien granted to the Collateral Agent in the Equity Interests of the Issuer, the Equity Interests of any Issuer Subsidiary Guarantors, all of the Issuer’s rights under the Samsung Construction Contract and, subject to certain exception, all other assets of the Issuer and any Issuer Subsidiary Guarantors. Upon execution and delivery of the Additional Collateral Agreements, the obligations of the Issuer and the Guarantors under the Indenture, the Notes and the Note Guarantees will also be secured by a Lien granted to the Collateral Agent in the Drilling Unit, the Earnings Account, proceeds of hull and machinery and loss of hire insurance in respect of the Drilling Unit and its operations and the Earnings derived from or related to a Drilling Contract.

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

8.2 Remedies Cumulative and Not Exclusive; No Waiver . No failure on the part of the Assignee or any other Secured Party to exercise, and no delay in exercising any right hereunder, shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. Neither the execution nor the delivery of this Assignment shall in any manner impair or affect other security for the Secured Obligations. The rights and remedies of the Assignee provided herein and in the other Note Documents are cumulative and are in addition to, and not exclusive of, any rights or remedies provided by law or otherwise.

(xii) recover from the Owner on demand all expenses, payments and disbursements (including fees and expenses of counsel) incurred by the Mortgagee in or about or incidental to the exercise by it of any or all of the powers vested in it hereunder;

PROVIDED, ALWAYS, that any sale of the Vessel by the Mortgagee pursuant to Section 7(b)(ix) above shall operate to divest all right, title and interest of the Owner, its successors and assigns, in or to the Vessel so sold and to bar any such interest of the Owner and all persons claiming through or under the Owner and upon such sale the purchaser shall not be bound to see or inquire whether the Mortgagee’s power of sale has arisen in the manner herein provided and the sale shall be deemed to be within the power of the Mortgagee and the receipt by the Mortgagee of the purchase money shall effectively discharge the purchaser who shall not be concerned with the manner of application of the proceeds of the sale or be in any way answerable therefor.

In case the Mortgagee shall have proceeded to enforce any right, power or remedy under this Mortgage by foreclosure, entry or otherwise, and such proceedings shall have been discontinued or abandoned for any reason (including as a consequence of a rescission of acceleration by the Holders pursuant to Section 6.02 of the Indenture) or shall have been determined adversely to the Mortgagee, then and in every such case the Owner and the Mortgagee shall be restored to their former positions and rights hereunder with respect to the property, subject or intended to be subject to this Mortgage, and all rights, remedies and powers of the Mortgagee shall continue as if no such proceedings had been taken.

In the event that the proceeds are insufficient to pay the amounts specified in Section 6.10(a) and (b) of the Indenture, the Mortgagee shall be entitled to collect the balance from the Owner or any other Person liable therefor.

9. No Waiver . No delay or omission of the Mortgagee to exercise any right or power or remedy vested in it under the Indenture, the Notes, this Mortgage, the other Note Documents or any of them shall impair such right or power or be construed as a waiver thereof or as acquiescence in any default by the Owner hereunder, nor shall the acceptance by the Mortgagee of any payments in connection with this Mortgage from any source be deemed a waiver hereunder. No single or partial exercise by the Mortgagee of any right, power or remedy nor the discontinuance, abandonment or adverse determination of any proceedings taken by the

Mortgagee to enforce any right, power or remedy shall preclude any other or further exercise thereof or proceedings to enforce the same or the exercise of any other right, power or remedy, nor shall the giving by the Mortgagee of any consent to any act which by the terms of this Mortgage requires such consent prejudice the right of the Mortgagee to give or withhold consent to the doing of any other similar act.

10. Delegation of Power . The Mortgagee shall be entitled at any time and as often as may be expedient to delegate all or any of the powers and discretions vested in it by this Mortgage (including the power vested in it by virtue of Section 12 hereof) in such manner and upon such terms and to such Persons as the Mortgagee in its absolute discretion may deem advisable.

(A) The Owner hereby irrevocably appoints the Mortgagee as its attorney-in-fact , until such time as the Secured Obligations are paid in full in cash, to do in the name of the Owner all acts which the Owner, or its successors or assigns, could do in relation to the Vessel, including without limitation, to demand, collect, receive, compromise, settle and sue for (insofar as the Mortgagee lawfully may) all freights, hire, earnings, issues, revenues, income and profits of the Vessel, and all amounts due from underwriters under the Insurances as payment of losses or as return premiums or otherwise, salvage awards and recoveries, recoveries in general average or otherwise, and all other sums due or to become due to the Owner in respect of the Vessel, and to make, give and execute in the name of the Owner, acquittance, receipts, releases or other discharges for the same, whether under seal or otherwise, to take possession of, sell or otherwise dispose of or manage or employ, the Vessel, to execute and deliver charters and a bill of sale with respect to the Vessel, and to endorse and accept in the name of the Owner all checks, notes, drafts, warrants, agreements and all other instruments in writing with respect to the foregoing; PROVIDED, HOWEVER, that, unless the context otherwise permits under this Mortgage, such power shall not be exercisable by or on behalf of the Mortgagee unless and until an Event of

Default has occurred and is continuing. The power of attorney hereby conferred shall be a general power of attorney and the Owner ratifies and confirms, and agrees to ratify and confirm, any deed, assurance, agreement, instrument, act or thing which the Mortgagee may execute or do pursuant thereto.

(B) The exercise of the power granted in this Section 12 by or on behalf of the Mortgagee shall not require any Person dealing with the Mortgagee to conduct any inquiry as to whether any Event of Default has occurred and is continuing, nor shall such Person be in any way affected by notice that any Event of Default has not occurred nor is continuing, and the exercise by the Mortgagee of such power shall be conclusive evidence of its right to exercise the same.

13. Appointment of Receiver . If any legal proceedings shall be taken to enforce any right under this Mortgage, the Mortgagee shall be entitled as a matter of right to the appointment of a receiver of the Vessel and of the freights, hire, earnings, issues, revenues, income and profits due or to become due and arising from the operation thereof.

14. Commencement of Proceedings . The Mortgagee shall have the right to commence proceedings in the courts of any country having competent jurisdiction and in particular the Mortgagee shall have the right to arrest and take action against the Vessel at whatever place the Vessel shall be found lying and the Owner agrees that for the purpose of proceedings against the Vessel any writ, notice, judgment or other legal process or documents may be served upon the Master of the Vessel (or upon anyone acting as the Master) and that such service shall be deemed good service on the Owner for all purposes.

15. Partial Invalidity . In the event that any provision or provisions of this Mortgage shall be declared invalid, void or otherwise inoperative by any present or future court of competent jurisdiction in any country, the Owner will, without prejudice to any other right and remedy of the Mortgagee under the Indenture, the Notes, this Mortgage, the other Note Documents, or any of them, execute and deliver such other and further instruments and do such things as in the reasonable opinion of the Mortgagee or its counsel will be necessary or advisable to carry out the true intent and spirit of this Mortgage. In any event, any such declaration of partial invalidity shall not affect the validity of any other provision or provisions of this Mortgage, or the validity of this Mortgage as a whole.

hereafter existing at law, in equity, admiralty, or by statute, and each and every power and remedy whether specifically in this Mortgage or in the Indenture or in the Notes or in the other Note Documents given or otherwise existing may be exercised from time to time and as often and in such order as may be deemed expedient by the Mortgagee, and the exercise or the beginning of the exercise of any such power or remedy shall not be construed to be a waiver of the right to exercise at the same time or thereafter any other power or remedy under the Indenture, the Notes, this Mortgage or any other Note Documents.

IN WITNESS WHEREOF, the Owner has executed this Mortgage by its duly authorized representative on the day and year first above written.

On this [•] day of [•] , 2013, before me personally appeared [•], to me known, who, being by me duly sworn, did depose and say that (s)he resides at [•], that (s)he is a/an [•] of PACIFIC DRILLING V LIMITED, the corporation described in and which executed the foregoing First Preferred Mortgage; and that (s)he signed his/her name thereto pursuant to authority granted to him/her by the Board of Directors of said corporation.

We have acted as your counsel regarding certain matters of the laws of the Republic of Liberia (“Liberia”) in connection with an Indenture, dated November , 2012 (the “Agreement”), made between you, as trustee (in such capacity, the “Trustee”) and as collateral agent (in such capacity, the “Collateral Agent”), Pacific Drilling V Limited, a British Virgin Islands company registered as a foreign maritime entity under the laws of Liberia (the “Shipowner”), as issuer, Pacific Drilling S.A., a Luxembourg corporation, and certain subsidiaries of the Shipowner, as guarantors, pursuant to which the Shipowner has issued to certain initial purchasers its 7.250% Senior Secured Notes due to mature in 2017 in an aggregate original principal amount of USD500,000,000, with a right to issue up to an additional aggregate principal amount of USD50,000,000 (totaling USD550,000,000) (collectively, the “Notes”). Unless otherwise defined herein, capitalized terms used herein shall have the meanings ascribed to them in the Mortgage (as defined below).

In rendering this opinion letter, we have examined executed copies of the following documents (collectively, the “Documents”):

In addition, in rendering this opinion letter we have examined and relied on originals or copies of the following documents:

Based upon and subject to the foregoing, and subject to the qualifications, limitations, exceptions, exclusions, and assumptions set forth herein, we are of the opinion that insofar as the laws of Liberia are concerned:

The opinions expressed herein are subject in all respects to the following qualifications, limitations, exceptions, exclusions, and assumptions:

(a) We qualify the opinions expressed herein as follows: (1) the enforceability of the rights and remedies provided for in the Documents (i) may be limited by insolvency, bankruptcy, reorganization, fraudulent conveyance, fraudulent transfer, fraudulent obligation, moratorium or other similar laws affecting generally the enforceability of creditors’ rights and remedies or the collection of debtor’s obligations from time to time in effect, and (ii) is subject to general principles of equity, regardless of whether such enforceability is considered in a proceeding in

equity or at law, including the application of principles of good faith, fair dealing, course of dealing, course of performance, commercial reasonableness, materiality, unconscionability and conflict with public policy and other similar principles; (2) different results might be obtained under the laws (other than the laws of Liberia) by which the Documents or any of them are expressed to be governed; (3) while there is nothing in the laws of Liberia which prohibits the Shipowner from submitting to the jurisdiction of a forum other than Liberia, the validity and the enforceability of the submission to jurisdiction provisions set forth in the Documents are not dependent upon such laws and such provisions may not be enforceable under the laws of another jurisdiction; (4) Liberian courts are not bound by a foreign judgment and have the right to review a case on the merits if a motion is made to the court to the effect that there is no merit to the case or the foreign court lacked jurisdiction; (5) certain of the remedial and self-help provisions of the Documents may be limited or rendered unenforceable by the laws of Liberia (but such limitations do not, in our opinion, make the enforcement remedies provided by the Documents unsatisfactory for the practical realization of the benefits provided thereby) or under the laws of other jurisdictions where enforcement may be sought; (6) obligations contained in documents referred to in the Documents but which are not attached to the Mortgage might not be secured by the Mortgage; and (7) enforcement of the Documents might not be available with respect to amounts that the Shipowner has merely stipulated are owing but have not been actually advanced or do not represent costs actually incurred.

(b) We express no opinion as to the availability of the remedy of specific performance as to any of the Documents, or as to the availability of equitable remedies, including injunctive relief, for the enforcement of any provision of any of the Documents.

(c) Notwithstanding anything to the contrary contained in the foregoing, we express no opinion as to the enforceability under the laws of Liberia of any provision of the Documents which purports to provide for the payment of, or to secure the obligation of the Shipowner to pay, interest on overdue interest or additional sums as a result of losses due to currency fluctuations subsequent to the granting of judgment by a court of competent jurisdiction.

(d) In rendering the opinions expressed in paragraph 1 above concerning the registration and good standing of the Shipowner as a foreign maritime entity in Liberia, we have relied solely on the Certificate of Goodstanding.

(e) In rendering the opinions expressed in paragraphs 3 and 4 above concerning the ownership of the Vessel and the recording of the Mortgage on the Vessel and the absence of liens or encumbrances of record on the Vessel filed prior in time to the Mortgage, we have relied solely on the Certificate of Ownership and Encumbrance.

(f) Except as specifically set forth in opinion paragraph 4 above concerning the recording of the Mortgage and the absence of liens of record on the Vessel filed prior in time to the Mortgage, we express no opinion regarding the creation, perfection or priority of any security interest or lien in your favor.
