The Notes may have other notations, legends or endorsements required by law, stock exchange rule or usage. Each Note shall be dated the date of its authentication. The terms of the Notes set forth in the Appendix are part of the terms of this Indenture. The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

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

SECTION 2.02. Execution and Authentication.

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

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

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

31

On the Issue Date, the Trustee shall authenticate and deliver Notes in an aggregate principal amount of $350,000,000 and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Notes for original issue in an aggregate principal amount specified in an authentication order of the Company. Such order shall specify the aggregate principal amount of the Notes to be authenticated, the date on which the original issue of Notes is to be authenticated and to whom the Notes shall be registered and delivered and, in the case of an issuance of Additional Notes pursuant to Section  2.14 after the Issue Date, shall certify that such issuance is in compliance with Section  4.09 ,

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

SECTION 2.03. Registrar and Paying Agent.

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

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

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

SECTION 2.04. Paying Agent to Hold Money in Trust.

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

32

SECTION 2.05. Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee in writing, at least five Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders.

SECTION 2.06. Transfer and Exchange.

The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note for registration of transfer and in compliance with the Appendix. When a Note is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture are met. When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. The Company may require payment of a sum sufficient to cover any taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section  2.06 (other than any such transfer taxes, assessments or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10 , 3.06 , 3.08 , 3.09 , 4.10 , 4.15 or 9.05 ).

SECTION 2.07. Replacement Notes.

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

Every replacement Note is an additional obligation of the Company.

SECTION 2.08. Outstanding Notes.

The Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in interests in a Global Note effected by the Trustee in accordance with the provisions hereof and those described in this Section 2.08 as not outstanding. Except as set forth in Section  2.09 , a Note does not cease to be outstanding because the Company, any Guarantor or an Affiliate of the Company or any Guarantor holds the Note.

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

SECTION 2.09. Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any Guarantor, or by any Affiliate of the Company or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee actually knows are so owned will be so disregarded. Notwithstanding anything in this Indenture to the contrary, no Person shall be deemed or presumed to have any such controlling interest, or to be under common

33

control of any other Person with the Company or any Guarantor, solely as a result of (i) such Person and/or such other Person being or becoming a party to the Shareholders Agreement (including exercising its rights thereunder) or (ii) such Person and/or such other Person being a Beneficial Owner of more than 10% of the Company’s outstanding Voting Stock, unless, in the case of the preceding clause (ii), such Person and/or such other Person (as determined in good faith by the Board of Directors of the Company) has the power, directly or indirectly, to direct or cause the direction of the management and policies of the Company, whether through the ownership of the Voting Stock of the Company, by contract (excluding for such purposes the Shareholders Agreement), or otherwise (excluding for all such purposes any shares of the Company’s Voting Stock held by any other party subject to the Shareholders Agreement attributable to such Person or such other Person as a result of the Shareholders Agreement).

SECTION 2.10. Temporary Notes.

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

SECTION 2.11. Cancellation.

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

SECTION 2.12. Defaulted Interest.

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

SECTION 2.13. CUSIP and ISIN Numbers.

The Company in issuing the Notes may use “CUSIP” numbers and corresponding “ISINs” (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers and corresponding “ISINs” in notices of redemption as a convenience to Holders; provided , however , that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee of any changes in “CUSIP” or “ISIN” numbers.

SECTION 2.14. Issuance of Additional Notes.

The Company shall be entitled, subject to its compliance with Sections 4.09 and 4.12 , to issue Additional Notes under this Indenture, which Additional Notes shall have identical terms and conditions as the Initial Notes issued on the Issue Date, other than with respect to the date of issuance, issue price and the date from which interest will accrue. The Initial Notes issued on the Issue Date, and any Additional Notes, will be equally and

34

ratably secured by the Liens granted to the First Lien Collateral Agent on the Collateral and shall be treated as a single class for all purposes under this Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase; provided , however , that in the event any Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such non-fungible Notes will be issued with a separate CUSIP or ISIN number so they are distinguishable from the Notes issued on the Issue Date.

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

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

(2) the issue price, the issue date (and the corresponding date from which interest shall accrue thereon and the first Interest Payment Date therefor) and the CUSIP number and any corresponding ISIN of such Additional Notes.

ARTICLE 3

REDEMPTION AND PREPAYMENT

SECTION 3.01. Notices to Trustee.

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

SECTION 3.02. Selection of Notes to Be Redeemed.

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

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. No Notes of $2,000 or less can be redeemed in part. Notes and portions of Notes selected shall be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder shall be redeemed. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

SECTION 3.03. Notice of Redemption.

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

35

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

(a) the redemption date;

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

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

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

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

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

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

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

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

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

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

SECTION 3.04. Effect of Notice of Redemption.

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

36

SECTION 3.05. Deposit of Redemption Price.

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

If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption whether or not such Notes are presented for payment, and the only remaining right of the Holders of such Notes shall be to receive payment of the redemption price upon surrender to the Paying Agent of the Notes redeemed. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section  4.01 .

SECTION 3.06. Notes Redeemed in Part.

Upon surrender of a Note that is redeemed in part, the Company shall issue in the name of the applicable Holder and the Trustee shall, upon its receipt of an authentication order from the Company, authenticate and mail to such Holder (or cause to be transferred by book entry) at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered representing the same Indebtedness to the extent not redeemed; provided that each new Note shall be in a principal amount of $2,000 and integral multiples of $1,000 in excess thereof. It is understood that, notwithstanding anything in this Indenture to the contrary, only an authentication order and not an Opinion of Counsel or Officers’ Certificate is required for the Trustee to authenticate such new Note.

SECTION 3.07. Optional Redemption.

(a) At any time prior to May 15, 2020, the Company may, at its option, redeem up to 35% of the aggregate principal amount of Notes (including any Additional Notes) issued under this Indenture, at one time or from time to time, at a redemption price equal to 109.250% of the principal amount thereof, plus accrued and unpaid interest and Additional Amounts, if any, to, but not including, the applicable redemption date (subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date), in an amount not greater than the net cash proceeds received by the Company from one or more Equity Offerings; provided that:

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

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

(b) At any time prior to May 15, 2020, the Company may, at its option, redeem the Notes, in whole or in part, at one time or from time to time, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest and Additional Amounts, if any, to, but not including, the applicable redemption date, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date. The Company shall calculate, or cause the calculation of, the Applicable Premium and the Trustee shall have no duty to calculate or verify the Company’s calculations thereof.

(c) At any time prior to May 15, 2020, not more than once in any 12-month period, the Company may, at its option, redeem up to $35.0 million in aggregate 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, but not including, 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.

37

(d) On or after May 15, 2020, the Company may, at its option, redeem the Notes, in whole or in part, at one time or from time to time, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest and Additional Amounts, if any, on the Notes redeemed, to, but not including, 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 May 15 of the years indicated below:

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

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

Notwithstanding the foregoing, no such notice of redemption may be given earlier than 60 days prior to the earliest date on which the Company or the relevant Guarantor, as applicable, would be obligated to pay Additional Amounts if a payment in respect of the Notes or the Guarantees were then due, and at the time such notice is given, the obligation to pay Additional Amounts must remain in effect. Before the Company mails or delivers notice of redemption of the Notes as described above, the Company shall deliver to the Trustee and Paying Agent (a) an Officers’ Certificate stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Company to so redeem have occurred and (b) an opinion of independent legal counsel of recognized standing that the Company or any Guarantor has or will become obligated to pay Additional Amounts as a result of the circumstances referred to in clause (1) or (2) of the preceding paragraph.

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

38

(f) If a Change of Control occurs at any time on or after May 15, 2019, the Company may redeem the Notes, at its option, in whole but not in part, 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, but not including, 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 periods below:

If the Company elects to exercise this redemption right, it must do so by delivering a redemption notice to each holder with a copy to the Trustee within 60 days following the Change of Control (or, at the Company’s option, prior to such Change of Control but after the transaction giving rise to such Change of Control is publicly announced). Any such redemption may be conditioned upon the Change of Control occurring if the notice is delivered prior to the Change of Control. If the Company exercises the Change of Control redemption right, it may elect not to make the Change of Control Offer pursuant to Section  4.15(a) unless it defaults in payments due upon redemption. Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the notes called for redemption on the applicable redemption date.

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

SECTION 3.08. Mandatory Petrobras Offer

(a) At such time as the Company or any Restricted Subsidiary has received Petrobras Recovery Proceeds in the form of cash or Cash Equivalents of at least $75 million, the Company shall, within 10 Business Days of receipt thereof make an offer (a “ Petrobras Offer ”) to all Holders (and holders of any other First Lien Debt containing provisions similar to those set forth in this Indenture with respect to offers to purchase, repay or redeem such First Lien Debt with Petrobras Recovery Proceeds) to purchase Notes (and to purchase, repay or redeem such other First Lien Debt on a pro rata basis) in an aggregate principal amount equal to at least $75 million (the “ Designated Petrobras Amount ”).

(b) The repurchase date in any Petrobras Offer (the “ Petrobras Offer Settlement Date ”) shall be specified by the Company, and, subject to the final sentence of this clause (b), shall be no earlier than 30 days and no later than 60 days from the date the notice of such Petrobras Offer is delivered pursuant to clause (c) below. The offer, repayment or redemption price in any Petrobras Offer will be equal to 100% of the principal amount of Notes or other First Lien Debt to be repurchased, repaid or redeemed, plus accrued and unpaid interest and Additional Amounts, if any, to, but not including, the date of repurchase, repayment or redemption, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date, and will be payable in cash. A Petrobras 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 “ Petrobras Offer Period ”) .

(c) Upon the commencement of a Petrobras Offer, the Company shall send, by first class mail, or otherwise in accordance with the requirements of the Depository, 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 Petrobras Offer. The notice, which shall govern the terms of the Petrobras Offer, shall state:

(i) that the Petrobras Offer is being made pursuant to this Section  3.08 and the duration of the Petrobras Offer Period, including the time and date the Petrobras Offer Period will terminate (the “ Petrobras Offer Termination Date ”) ;

39

(ii) the Designated Petrobras Amount and the purchase price;

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

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

(v) that Holders electing to have a Note purchased pursuant to the Petrobras 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 Company may reasonably request, to the Company or a Paying Agent at the address specified in the notice, before the Petrobras Offer Termination Date;

(vi) that Holders shall be entitled to withdraw their election if the Company or the Paying Agent, as the case may be, receives, prior to the Petrobras 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 and other First Lien Debt tendered in such a Petrobras Offer collectively exceeds the Designated Petrobras Amount, the Company will select the Notes and such other First Lien Debt for purchase, repayment or redemption on a pro rata basis unless otherwise required by law or applicable stock exchange or Depository requirements (with such adjustments as may be deemed appropriate by the Company so that only Notes and other First Lien Debt in denominations of $2,000 and integral multiples of $1,000 in excess thereof will be outstanding after such repurchase, repayment or redemption); 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 $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

(d) Promptly after the Petrobras Offer Termination Date, the Company shall, to the extent lawful, accept for payment Notes or portions thereof properly tendered and not withdrawn pursuant to the Petrobras Offer in the aggregate principal amount required by this Section  3.08 .

41

(vii) that, if the aggregate principal amount of Notes or other First Lien Debt surrendered by Holders and holders of such other First Lien Debt, collectively, exceeds the Asset Sale Offer Amount, the Company shall select the Notes and such other First Lien Debt to be purchased from the amount allocated therefor on a pro rata basis unless otherwise required by law or applicable stock exchange or Depository requirements (with such adjustments as may be deemed appropriate by the Company so that only Notes and First Lien Debt in denominations of $2,000 and integral multiples of $1,000 in excess thereof will be outstanding after such purchase); 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 $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

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

SECTION 4.06. Stay, Extension and Usury Laws.

Each of the Company 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 Company 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.

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

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

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

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

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

(11) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness not otherwise permitted pursuant to clauses (1) through (10) above or clauses (12) through (16) below in an amount, together with any other Indebtedness Incurred pursuant to this clause (11) then outstanding, not in excess of $135 million;

(14) Indebtedness, Disqualified Stock or Preferred Stock of a joint venture to the Company or a Restricted Subsidiary and to other holders of Equity Interests or participants of such joint venture so long as (i) the percentage of the aggregate amount of such Indebtedness, Disqualified Stock or Preferred Stock of such joint venture owed to such holders of its Equity Interests does not exceed the percentage of the aggregate outstanding amount of the Equity Interests of such joint venture held by such holders and (ii) the amount of such Indebtedness, Disqualified Stock or Preferred Stock, together with any other Indebtedness, Disqualified Stock and Preferred Stock Incurred or issued pursuant to this clause (14) then outstanding, does not exceed $25 million;

52

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 (16) above or could be Incurred pursuant to Section  4.09(a) , the Company or the applicable Restricted Subsidiary will be permitted to classify such item of Indebtedness (or any portion thereof) on the date of its Incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section  4.09 . The accrual of interest or Preferred Stock dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms (including the payment of paid-in-kind (or “PIK”) interest with respect to the Existing Convertible Notes), 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 (excluding the payment of paid-in-kind (or “PIK”) interest with respect to the Existing Convertible Notes) is included in Consolidated Interest Expense of the Company as accrued.

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

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

(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:

(A) the Fair Market Value of such assets at the date of determination; and

(B) the amount of the Indebtedness of the other Person; and

(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.

(c) Notwithstanding anything to the contrary in this Indenture, the Company will not, and will not permit any Guarantor to, directly or indirectly, Incur any Indebtedness (including Acquired Debt) that is contractually subordinated in right of payment to any Indebtedness of the Company or such Guarantor, as the case may be, unless such Indebtedness is expressly subordinated in right of payment to the Notes or such Guarantor’s Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Company or such Guarantor, as the case may be; provided , however , that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured or by virtue of being secured on a junior Lien basis.

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 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.

53

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

For the avoidance of doubt, any reversal of the satisfaction and discharge of the indenture governing the Second Lien Notes or failure to consummate the redemption of such Second Lien Notes as described in the Offering Circular shall be deemed to be an Incurrence of Indebtedness and Liens in respect of such Second Lien Notes.

SECTION 4.10. Limitation on Asset Sales.

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

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

(2) at least 75% of the consideration received in such Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents;

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

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

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

(2) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are, within 180 days after receipt thereof, converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents, to the extent of the cash or Cash Equivalents received in that conversion; provided, however , that to the extent such securities consist of publicly-traded common equity securities of a Public Company having a world-wide market capitalization of at least $500 million at the time of receipt by the Company or the applicable Restricted Subsidiary, such 180-day period shall be extended to 365 days (and provided, further , that a binding commitment made within such 365-day period by the Company or the applicable Restricted Subsidiary to convert such securities into cash or Cash Equivalents shall be permitted under this clause (2) so long as such securities are actually so converted within 545 days from the receipt thereof); and

(3) any Designated Noncash Consideration received by the Company or any of the Restricted Subsidiaries from the transferee having an aggregate Fair Market Value, taken together with all other Designated Noncash Consideration received pursuant to this clause (3) that is at that time outstanding, not to exceed $25 million at the time of the receipt of such Designated Noncash Consideration (with the Fair Market Value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value).

54

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

(1) (a) to purchase, repay or prepay Superpriority Debt (and, if such Superpriority Debt consists of revolving debt, to correspondingly reduce commitments with respect thereto) or cash collateralize letters of credit in respect of Superpriority Debt or (b) to purchase, repay or prepay First Lien Debt other than Superpriority Debt; provided that, to the extent purchases, repayments or prepayments of any First Lien Debt are made pursuant to this clause (1)(b), the Company shall equally and ratably redeem the Notes as provided in Section  3.07 or repay or offer to repay Notes, through open-market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an offer to Holders in accordance with the procedures set forth in Section  3.09 and this Section  4.10 for an Asset Sale Offer;

(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 as a result of such acquisition;

(3) to make a capital expenditure that is used or useful in a Permitted Business; 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, Collateral Vessels, related assets and any related Ready for Sea Costs) or make any deposit, installment or progress payment in respect of such assets or payment of any related Ready for Sea Costs,

provided that (x) a binding commitment made within the 365-day period described above by the Company or the applicable Restricted Subsidiary to apply Net Proceeds from an Asset Sale in accordance with clauses (2), (3) and/or (4) above shall satisfy the requirements of such clauses with respect to such Net Proceeds so long as such Net Proceeds are actually so applied within 545 days from the receipt thereof from such Asset Sale 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 clause (2), (3) or (4) above, the Company shall, or shall cause the applicable Restricted Subsidiary to, pledge any assets (including, without limitation, any acquired Capital Stock) acquired with such Net Proceeds to secure the Notes Obligations on a first-priority secured basis (subject to the payment priority in favor of the holders of Superpriority Debt, if any, set forth in the Collateral Documents and subject to Permitted Collateral Liens) pursuant to the Collateral Documents in accordance with this Indenture.

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

(e) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section  4.10(c) will constitute “ Excess Proceeds . ” When the aggregate amount of Excess Proceeds exceeds $20 million, the Company shall, within 10 Business Days thereof, make an offer (an “ Asset Sale Offer ”) in accordance with Section  3.09 to all Holders and holders of any other First Lien Debt containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem such First Lien Debt with the proceeds of sales of assets to purchase, prepay or redeem the Notes and such other First Lien Debt on a pro rata basis in an aggregate principal amount equal to the Excess Proceeds. The repurchase date in any Asset Sale Offer shall be specified by the Company, which date will be no earlier than 30 days and no later than 60 days from the date the notice of such Asset Sale Offer is delivered. 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, but not including, the date of purchase, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company and the Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes or other First Lien Debt tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company will select the Notes and other First Lien Debt for purchase on a pro rata basis unless otherwise required by law or applicable stock exchange or Depository requirements (with such adjustments as may be deemed appropriate by the Company so that only Notes and other First Lien Debt in denominations of $2,000 and integral multiples of $1,000 in excess thereof will be outstanding after such purchase). For the purposes of calculating the principal amount of any such Indebtedness not

55

denominated in U.S. dollars, such Indebtedness shall be calculated by converting any such principal amounts into their Dollar Equivalent determined as of the Business Day immediately prior to the date on which the Asset Sale Offer is announced. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(f) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those requirements, laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of this Indenture, the Company shall 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.

(g) The provisions of this Section  4.10 with respect to the Company’s obligation to make an Asset Sale Offer as a result of an Asset Sale may be waived or modified at any time with the written consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding.

SECTION 4.11. Limitation on Transactions with Affiliates.

(a) The Company will not, and will not permit any of the Restricted Subsidiaries to, make any payment to, or sell, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each, an “ Affiliate Transaction ”) involving, with respect to any such transaction or series of related transactions, payments or consideration in excess of $1 million, unless:

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

(2) the Company delivers to the Trustee:

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25 million, a resolution of the Board of Directors of the Company accompanied by an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section  4.11 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company; and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50 million, an opinion issued to the Board of Directors of the Company by an accounting, appraisal or investment banking firm of international standing or generally recognized in the shipping or offshore drilling industries as qualified to perform the tasks for which such firm has been engaged as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction from a financial point of view or that the terms of such Affiliate Transaction are no less favorable to the Company or the relevant Restricted Subsidiary, taken as a whole, than those that could have been obtained in a comparable arm’s-length transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of the Company.

56

For the avoidance of doubt, with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration of $25 million or less, the determination that such Affiliate Transaction or series of Affiliate Transactions complies with this Section  4.11 may be made by a Financial Officer of the Company.

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

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

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

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

(7) Permitted Investments (other than Investments permitted by clause (3) of the definition thereof) and Restricted Payments that do not violate the provisions of Section  4.07 ;

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

(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 materially less favorable, taken as a whole, to the Holders); and

(10) transactions with customers, clients, suppliers, joint venture partners or purchasers or sellers of goods or services, in each case in the ordinary course of business of the Company and the Restricted Subsidiaries and otherwise in compliance with the terms of this Indenture; provided that in the reasonable determination of the Board of Directors or management of the Company, such transactions are on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that could have been obtained at the same time of such transactions in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person.

57

SECTION 4.12. Limitation on Liens.

The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist (i) any Lien of any kind on any Collateral, except 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.

SECTION 4.13. Additional Guarantees.

If (i) the Company acquires or creates any Restricted Subsidiary (other than an Immaterial Subsidiary), or (ii) as of the date of any financial statements delivered pursuant to Section  4.03 , a Restricted Subsidiary that was previously an Immaterial Subsidiary has ceased to meet the definition thereof (but remains a Restricted Subsidiary), then the Company will (1) cause such Subsidiary to, within 20 Relevant Business Days of such event, (x) execute and deliver to the Trustee a supplemental indenture substantially in the form of Annex A hereto pursuant to which such Person will become a Guarantor and (y) execute amendments to the Collateral Documents pursuant to which it will grant a Lien on any Collateral held by it in favor of the First Lien Collateral Agent, for the benefit of the Holders, and become a Collateral Grantor thereunder, and cause such Liens to be perfected as required thereby and (2) deliver to the Trustee and First Lien Collateral Agent one or more opinions of counsel in connection with the foregoing as specified in this Indenture.

SECTION 4.14. Existence.

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

SECTION 4.15. Offer to Repurchase Upon Change of Control.

(a) If a Change of Control occurs, the Company shall make an offer (a “ Change of Control Offer ”) to each Holder to repurchase all or any part (equal to a minimum amount of $2,000 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, but not including, the date of purchase (the “ Change of Control Payment Date ”), subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date. No later than 30 days following any Change of Control, the Company shall deliver a notice to the Trustee and paying agent and each Holder describing the transaction or transactions that constitute the Change of Control and stating:

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

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

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

58

(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 $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

The Company shall 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 Company shall 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.

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

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

(f) The provisions of this Section  4.15 relating to the Company’s obligation to make a Change of Control Offer, including the definition of “Change of Control,” may be waived or modified at any time (including after a Change of Control) with the written consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding.

SECTION 4.16. Payments for Consent.

The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any cash consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture, any 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.

Notwithstanding the foregoing, the Company and the Guarantors shall be permitted, in connection with any offer or payment of consideration for, or as an inducement to, any consent, waiver or amendment of any of the terms or provisions of this Indenture, any Guarantee or the Notes, to exclude Holders in any jurisdiction or any category of Holders where (1) the solicitation of such consent, waiver or amendment, including in connection with any tender or exchange offer, or (2) the payment of the consideration therefor, could reasonably be interpreted as requiring the Company or any Guarantor to file a registration statement, prospectus or similar document under any applicable securities laws or listing requirements (including, but not limited to, the U.S. federal securities laws and the laws of the European Union or any of its member states), which the Company in its sole discretion reasonably determines (acting in good faith) (a) would be materially burdensome (it being understood that it would not be materially burdensome to file the consent documents used in other jurisdictions, any substantially similar documents or any summary thereof with the securities or financial services authorities in such jurisdiction); or (b) such solicitation would otherwise not be permitted under applicable law in such jurisdiction or with respect to such category of Holders.

SECTION 4.17. Designation of Restricted and Unrestricted Subsidiaries.

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

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

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

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

(4) the Company delivers to the Trustee an Officers’ Certificate giving effect to such designation.

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

60

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

(1) the Company and the Restricted Subsidiaries may Incur the Indebtedness and Liens (and the Company and the Restricted Subsidiaries shall be deemed to Incur such Indebtedness and Liens upon such designation) of such Subsidiary under Sections 4.09 and 4.12 ;

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

(3) the Company delivers to the Trustee an Officers’ Certificate giving effect to such designation.

SECTION 4.18. Business Activities.

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

SECTION 4.19. Partial Vessel Transfers.

The Company and the Guarantors shall be permitted to transfer partial interests in a Collateral Vessel in a transaction that complies with the terms of this Indenture, including Section  4.10 and Section  5.01 and upon completion of the following:

(a) the Company shall give the First Lien Collateral Agent written notice of any such proposed transfer not fewer than 14 days prior to the anticipated date of such transfer;

(b) any bill of sale or other instrument of partial transfer shall state on its face that the interest transferred is subject to the Lien of the relevant Vessel Mortgage;

(c) the relevant Collateral Vessel will be duly re-registered in the joint names of the transferor Guarantor and the transferee showing the individual percentage interest held by each under the laws and flag of the relevant jurisdiction simultaneously with such transfer and evidence thereof delivered to the First Lien Collateral Agent on such date;

(d) simultaneously with such transfer the transferee will acknowledge in writing to the First Lien Collateral Agent that it takes its interest subject to the Vessel Mortgage;

(e) on the same date of such transfer, the Company shall deliver to the First Lien Collateral Agent a certificate of ownership and encumbrance or similar certificate issued by the jurisdiction of registration of the Collateral Vessel evidencing (x) re-registration in the joint names of the transferor Guarantor and the transferee and (y) the continuance of the Vessel Mortgage in favor of the First Lien Collateral Agent; and

(f) the Company shall cause to be delivered to the First Lien Collateral Agent on the same date of such transfer a legal opinion from outside counsel reasonably satisfactory to the First Lien Collateral Agent to the following effect (i) the Collateral Vessel is duly registered (preliminarily registered if the jurisdiction is Panama) in the joint names of the transferor Guarantor and the transferee with the appropriate authorities of the Collateral Vessel’s jurisdiction of registry; (ii) the Vessel Mortgage continues to constitute the legal, valid and binding obligation of the transferor Guarantor and remains duly registered as a First Lien Vessel Mortgage in favor of the First Lien Collateral Agent with priority dating back to the date on which such First Lien Vessel Mortgage was initially registered in favor of the First Lien Collateral Agent; (iii) all pledges of Collateral relating to the Collateral Vessel continue to constitute legal, valid and binding obligations of the transferor Guarantor; (iv) all filings and consents with respect to such transfer in the relevant jurisdictions have been obtained or made; and (v) such transfer is in compliance with the terms of this Indenture. Such legal opinion shall be in form and substance reasonably satisfactory to the First Lien Collateral Agent. The counsel issuing such opinion may rely on local counsel admitted to practice in the jurisdiction of registration of the Collateral Vessel with respect to matters

61

governed by the laws of such jurisdiction. If the Collateral Vessel transferred is registered under the laws and flag of Panama, the Company shall also deliver to the First Lien Collateral Agent an opinion of Panamanian counsel reasonably satisfactory to the First Lien Collateral Agent not later than five (5) months after the date of transfer confirming that such Collateral Vessel has been permanently registered in the joint names of the transferor Guarantor and the transferee.

SECTION 4.20. Rights to Earnings from the Collateral Vessels.

(a) The Company shall not permit any of the Restricted Subsidiaries (other than any Guarantor) to be the owner of a Vessel or an Internal Charterer, or to be subject to a Contract Winning Trigger. The Company shall, or shall cause one or more of the Guarantors to, cause all Earnings paid or payable to the Company or any Guarantor under each Drilling Contract to be deposited into one or more Earnings Accounts and at all times maintain the Earnings Accounts. Each Earnings Account shall at all times be in the name of the Company or a Guarantor and be subject to an account control agreement (or other comparable arrangement under applicable laws) effective to perfect the first priority security interest of the First Lien Collateral Agent for the benefit of Holders (except for deposit accounts that are Excluded Property).

(b) Notwithstanding Section 4.20(a), if the terms of a Drilling Contract or any applicable legal requirements require that any such Earnings be paid to a non-United States bank account by the counterparty to such Drilling Contract, this Section  4.20 shall not be deemed violated if funds standing to the credit of such account are transferred as soon as reasonably practicable after deposit thereof in the jurisdiction in which the account is located to an account that qualifies as an Earnings Account.

SECTION 4.21. Reflagging.

(a) The Company shall not and shall not permit any Guarantor to change the state of registration of a Collateral Vessel from its state of registration as of the Issue Date (or as of the date it becomes a Collateral Vessel, if later) to any other jurisdiction; provided that the state of registration of any Collateral Vessel may be changed to an Approved Flag State if:

(1) a replacement mortgage and, if applicable, deed of covenants is entered into by the applicable Guarantor;

(2) the replacement mortgage is registered with the new state of registration; and

(3) an opinion of counsel selected by the Board of Directors of the Company, acting in good faith, is provided to the First Lien Collateral Agent confirming the enforceability of the replacement mortgage and its due registration, in each case, as soon as reasonably practicable following the release of the mortgage over the applicable Collateral Vessel.

The First Lien Collateral Agent shall, at the cost of the Company, release the mortgage and other applicable security over the applicable Collateral Vessel, and take such other steps as may be reasonably required in connection with a change of the state of registration of a Collateral Vessel provided that the Company and the Guarantors provide the documents listed above as soon as reasonably practicable upon the release of the mortgage and other applicable security over the applicable Collateral Vessel.

SECTION 4.22. Payment of Additional Amounts.

(a) All payments made by or on behalf of the Company or any Guarantor under or with respect to the Notes or the 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 Cayman Islands or any political subdivision or any authority or agency therein or thereof having power to tax, or any other jurisdiction in which the

62

Company or any Guarantor (including any successor entity) is organized, incorporated, engaged in business or is otherwise resident or treated as resident for tax purposes, or any jurisdiction from or through which payment is made (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 Guarantees, the Company, the relevant Guarantor or other payor, as applicable, will pay such additional amounts (the “ Additional Amounts ”) as may be necessary so that the net amount received in respect of such payments by each Holder after such withholding or deduction (including any withholding or deduction from Additional Amounts) will not be less than the amount such Holder would have received if such Indemnified Taxes had not been withheld or deducted; provided , however , that Indemnified Taxes do not include:

(1) any Taxes to the extent such Taxes would not have been so imposed but for the Holder (or a fiduciary, settlor, beneficiary, member or shareholder of such Holder, if such Holder is an estate, a trust, a partnership, or a corporation) having any present or former connection with the Specified Tax Jurisdiction, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member or shareholder) being or having been a citizen or resident thereof or being or having been engaged in a trade or business or present therein or having, or having had, a permanent establishment therein (other than the mere acquisition, ownership, holding, enforcement, exercise of rights or receipt of payment in respect of the Notes or the Guarantees);

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

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

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

(5) [Reserved];

(6) 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;

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

(8) Taxes imposed pursuant to sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the “ Code ”), any regulations thereunder or official interpretations thereof, any intergovernmental agreement between the United States and another jurisdiction facilitating the implementation thereof (or any fiscal or regulatory legislation, rules or practices implementing such an intergovernmental agreement), or any agreement entered into pursuant to section 1471(b)(1) of the Code; or

63

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

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

(c) The Company or the relevant Guarantor or applicable withholding agent, as applicable, will make all withholdings and deductions required by law and will remit the full amount deducted or withheld to the relevant governmental authority on a timely basis in accordance with applicable law. As soon as practicable, the Company or the relevant Guarantor or applicable withholding agent, as applicable, will provide the Trustee and Paying Agent with an official receipt or, if official receipts are not obtainable, other documentation reasonably satisfactory to the Trustee and Paying Agent evidencing the payment of the Taxes so withheld or deducted. Upon request, copies of those receipts or other documentation, as the case may be, will be made available by the Company 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 Guarantees, such reference will be deemed to include payment of Additional Amounts as described in this Section  4.22 to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. For the avoidance of doubt, with respect to Notes represented by a Global Note, a Holder with respect to Additional Amounts and the related provisions of this Indenture shall be deemed to include a Holder representing the interests of a beneficial owner of the Notes or acting on behalf of a beneficial owner of the Notes.

(e) The Company or the relevant Guarantor, as applicable, will 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 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 Guarantees, and the Company or the relevant Guarantor, as applicable.

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

SECTION 4.23. Suspended Covenants.

(a) During any period of time (1) the Notes have an Investment Grade Rating and (2) no Default or Event of Default has occurred and is continuing under this Indenture, the Company and the Restricted Subsidiaries will not be subject to the provisions of Sections 3.08 , 4.07 , 4.08 , 4.09 , 4.10 , 4.11 and 5.01(a)(4) of this Indenture (collectively, the “ Suspended Covenants ”) .

64

(b) In the event that the Company and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of Section  4.23(a) and, subsequently, Moody’s or S&P withdraws its rating or downgrades the rating 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 (the “ Reversion Date ”), then the Company and the Restricted Subsidiaries shall, on and after the Reversion Date, be subject to the Suspended Covenants. The period of time between the date the Suspended Covenants become suspended and the Reversion Date is referred to herein as the “ Suspension Period . ” During the Suspension Period, the Board of Directors of the Company may not designate any of the Restricted Subsidiaries as Unrestricted Subsidiaries pursuant to Section  4.17 . Notwithstanding that the Suspended Covenants may be reinstated, no Default, Event of Default or breach of any kind under this Indenture or the Notes will be deemed to have occurred as a result of a failure of the Company and the Restricted Subsidiaries to comply with a Suspended Covenant during the Suspension Period.

(c) 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, but not during the Suspension Period, and no Default or Event of Default will be deemed to have occurred solely by reason of a Restricted Payment made during the Suspension Period. On the Reversion Date, all Indebtedness Incurred during the continuance of the Suspension Period will be classified as having been incurred pursuant to clause (2)(a) of Section  4.09(b) .

(d) The Company shall provide the Trustee and Holders with prompt written notice of any event or events giving rise to a Suspension Period or a Reversion Date, the date thereof and identifying the Suspended Covenants. The Trustee shall have no duty to monitor the ratings of the Notes or the occurrence of a Suspension Period or a Reversion Date, or to notify Holders of the same.

(e) Notwithstanding that the Suspended Covenants may be reinstated, without causing a Default or Event of Default, following a Reversion Date the Company and the Restricted Subsidiaries shall be permitted to honor any contractual commitments entered into during the Suspension Period ; provided that such contractual commitments were entered into during the Suspension Period and not in contemplation of a reversion of the Suspended Covenants.

SECTION 4.24. [Reserved].

SECTION 4.25. Maintenance of Property.

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

65

(b) at the request of the First Lien Collateral Agent (acting at the direction of Holders of a majority in aggregate principal amount of the Notes then outstanding), 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 Documents.

SECTION 4.27. Limitation on Certain Agreements.

The Company shall not permit any Collateral Grantor to enter into any agreement that requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or otherwise acquire or retire any Indebtedness of any Person, other than (i) the Notes, (ii) any other First Lien Obligations (so long as the Notes are required to be repaid, redeemed, defeased, acquired or retired on a ratable basis with such other First Lien Obligations), (iii) the Existing Convertible Notes or (iv) otherwise as may be permitted or required by this Indenture or the Collateral Documents, including with respect to any Permitted Collateral Liens; provided that any such agreement may be entered into to the extent it permits such proceeds to be applied to First Lien Obligations (including the Notes) prior to or instead of such other Indebtedness.

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

SECTION 6.02. Acceleration.

Subject to the succeeding sentence, if any Event of Default occurs and is continuing, the Trustee, by written notice to the Company, or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes, by written notice to the Company and the Trustee, may declare all the Notes to be due and payable immediately. Notwithstanding the preceding sentence, if an Event of Default specified in clause (i) or (j) of Section  6.01 occurs, all outstanding Notes shall become due and payable immediately without further action or notice.

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.

SECTION 6.03. Other Remedies.

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.

70

SECTION 6.04. Waiver of Past Defaults.

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.

SECTION 6.05. Control by Majority.

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 and First Lien Collateral Agent shall be entitled to indemnification or security (or both) satisfactory to the Trustee and First Lien Collateral Agent, respectively, against all loss, liability and expenses caused by the taking or not taking of such action.

SECTION 6.06. Limitation on Suits.

Except to enforce the right 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 the Trustee 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.

SECTION 6.07. Rights of Holders of Notes to Receive Payment.

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.

71

SECTION 6.08. Collection Suit by Trustee.

If an Event of Default specified in Section  6.01(a) or ( b ) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company and the Guarantors for the whole amount of principal of, interest, premium, if any, and Additional Amounts, if any, remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and Additional Amounts, if any, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09. Trustee is Authorized to File Proofs of Claim.

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 and First Lien Collateral Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, First Lien Collateral Agent, and each of their agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee and First Lien Collateral Agent 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 and First Lien Collateral Agent under Section  7.06. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, First Lien Collateral Agent, and each of their agents and counsel, and any other amounts due the Trustee and First Lien Collateral Agent 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.

SECTION 6.10. Priorities.

If the Trustee collects any money pursuant to this Article 6, subject to the Intercreditor Agreement and the Collateral Agency Agreement, it shall pay out the money in the following order:

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

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

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

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

72

SECTION 6.11. Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section  6.07 , or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

SECTION 6.12. The First Lien Collateral Agent.

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 First Lien Collateral Agent in the exercise of any of the rights and remedies available to the First Lien Collateral Agent pursuant to the Collateral Documents.

ARTICLE 7

TRUSTEE

SECTION 7.01. Duties of Trustee.

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

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

SECTION 7.04. Trustee’s Disclaimer.

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

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 the Trustee in good faith determines that withholding the notice is in the interests of the Holders.

SECTION 7.06. Compensation and Indemnity.

The Company shall pay to the Trustee from time to time such reasonable compensation as the Company and the Trustee may agree in writing for the Trustee’s acceptance of this Indenture and services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust.

Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

The Trustee shall notify the Company and the Guarantors promptly of any claim for which it may seek indemnity.

The Trustee may have separate counsel and the Company and the Guarantors shall pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

75

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

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

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

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

SECTION 7.07. Replacement of Trustee.

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

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

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

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

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

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

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

If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply with Section  7.09 , such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section  7.06 . Notwithstanding replacement of the Trustee pursuant to this Section  7.07 , the Company’s and the Guarantors’ obligations under Section  7.06 shall continue for the benefit of the retiring Trustee.

76

SECTION 7.08. Successor Trustee by Merger, etc.

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.

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

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

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

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

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

SECTION 9.02. With Consent of Holders of Notes.

Except as provided above in Section  9.01 and below in this Section  9.02 , the Company, the Guarantors, the Trustee and the First Lien Collateral Agent may amend or supplement this Indenture, the Notes and the Collateral Documents by the execution of a supplemental indenture or, in the case of any amendment or supplement to the Collateral Documents, by the execution of an appropriate amendment or supplement thereto, with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) and, subject to Sections 6.04 and 6.07 , any existing Default or Event of Default or compliance with any provision of this Indenture, the Notes, the Guarantees or any Collateral Document may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), in each case in addition to any required consent of holders of other First Lien Obligations that may be required with respect to an amendment of or waiver under a Collateral Document. 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;

82

(b) reduce the principal of, or change the fixed maturity of, any Note or alter the premium payable upon any redemption or repurchase of the Notes pursuant to Sections 3.08 , 3.09 , 4.10 and 4.15 ;

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

(d) 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);

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

(f) 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;

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

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

(i) subordinate the Notes or the Guarantees in right of payment to any other Indebtedness; or

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

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

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

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

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

SECTION 9.03. Consents in Connection with Purchase, Tender or Exchange.

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.

83

SECTION 9.04. Revocation and Effect of Consents.

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

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

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.

SECTION 9.05. Notation on or Exchange of Notes.

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

SECTION 9.06. Trustee to Sign Amendments, etc.

The Trustee shall sign any amendment or supplemental indenture or grant any waiver authorized pursuant to this Article 9 if the amendment or supplemental indenture or waiver does not adversely affect its rights, duties, liabilities or immunities. If any such amendment, supplemental indenture or waiver does adversely affect the rights, duties, liabilities or immunities of the Trustee, the Trustee may, but need not, sign such amendment, supplemental indenture or grant such waiver. In executing any such amendment, supplemental indenture or waiver, the Trustee shall be entitled to receive and (subject to Section  7.01 ) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment, supplemental indenture or waiver is authorized or permitted by this Indenture and the Collateral Documents, constitutes the legal, valid and binding obligation of the Company, enforceable against it in accordance with its terms and that all conditions precedent to such supplemental indenture have been complied with, subject to customary assumptions and qualifications.

SECTION 9.07. Acts of Holders.

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

84

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 Depository shall be deemed to constitute the Act of the Holder of such Global Note, and such Act shall be deemed to have been delivered to the Company and the Trustee upon the delivery by the Depository 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 Depository.

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

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

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

ARTICLE 10

GUARANTEES OF NOTES

SECTION 10.01. Subsidiary Guarantees.

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

(a) the principal of, and premium, if any, interest, if any, on, or Additional Amounts, if any, on, the Notes will be promptly paid in full when due, whether at Stated Maturity, by acceleration, upon repurchase or redemption or otherwise, and interest on the overdue principal of, and premium, if any, and (to the extent permitted by law) interest, if any, on, and Additional Amounts, if any, on, the Notes, and all other payment Obligations of the Company to the Holders, the Trustee or the First Lien 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.

85

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

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

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

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

SECTION 10.02. Releases of Guarantees.

The Guarantee of a Guarantor will be automatically and unconditionally released: (1) in connection with any sale, transfer or other disposition (including by merger, consolidation, amalgamation, distribution, dividend or otherwise) of all or substantially all of the assets of such Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition is conducted in accordance with Sections 4.10 and 5.01(b) , as applicable; (2) in connection with any sale, transfer or other disposition (including by merger, consolidation, amalgamation, distribution, dividend or otherwise) of all of the Capital Stock of such Guarantor, following which such Guarantor is no longer a Restricted Subsidiary of the Company, if the sale or other disposition is conducted in accordance with Sections 4.10 and 5.01(b) , as applicable; (3) upon Legal Defeasance, Covenant Defeasance or Discharge in accordance with Article 8 ; (4) unless an Event of Default has occurred and is continuing, upon the dissolution or liquidation of such Guarantor in compliance with Section  5.01(b) ; or (5) if the Company designates such Guarantor as an Unrestricted Subsidiary or an Immaterial Subsidiary in accordance with this Indenture.

Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that any of the conditions described in the foregoing clauses (1) through (5) has occurred, the Trustee shall execute any documents reasonably requested by the Company at the Company’s expense in order to evidence the release of any Guarantor from its obligations under its Guarantee. Any Guarantor not released from its obligations under its 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 .

86

SECTION 10.03. Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the 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 Guarantee, and with respect to any Guarantor organized under the laws of Malaysia, the amount of the obligations guaranteed by such Guarantor (and the value of any assets provided by such Guarantor as security for such obligations) shall be in, but not in excess of, the maximum amount permitted by any Legal Requirement applicable to such Guarantor, including, but not limited to, the Malaysian Financial Services Act of 2013, as amended, and any rules, regulations, or rulings promulgated by Bank Negara Malaysia (or any successor central bank of Malaysia). The obligations of each Guarantor under its 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 Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Guarantor under its 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 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.

SECTION 10.04. “Trustee” to Include Paying Agent.

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.

SECTION 10.05. Execution and Delivery.

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

SECTION 10.06. Subrogation.

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

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

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

The Company will pay interest semi-annually in arrears on May 15 and November 15 of each year (each an “ Interest Payment Date ”), commencing May 15, 2019.

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. 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 Company 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 Company 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 1 or November 1 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 contiguous United States, or, at the option of the Company, 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 Company 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.
