Section .	Replacement Notes.

(a)If any mutilated Note is surrendered to the Registrar, the Transfer Agent or the Issuer and the Registrar, Transfer Agent and the Issuer receive evidence to their satisfaction of the destruction, loss or theft of any Note, the Issuer shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate or cause the Authentication Agent to authenticate a replacement Note if the Trustee’s requirements are met. An indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any Authentication Agent from any loss that any of them may suffer if a Note is replaced. The Issuer may charge the Holder for its expenses in replacing a Note, including reasonable fees and expenses of counsel and the Trustee. In the event of any such mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Issuer in its discretion may pay such Note instead of issuing a new Note in replacement thereof.

(b)Every replacement Note is an additional obligation of the Issuer and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

(c)The provisions of this Section 2.07 are exclusive and preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or wrongfully taken Notes.


Section .	Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest 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 hereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note; however, Notes held by the Issuer or an Affiliate of the Issuer shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof.

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If a Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.


Section .	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 Issuer or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer, 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 a Responsible Officer of the Trustee actually knows are so owned will be so disregarded.


Section .	Temporary Notes.

(a)Until certificates representing Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate or cause the Authentication Agent to authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes and as such shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes.

(b)Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.


Section .	Cancellation.

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar, each Paying Agent and any Transfer Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy canceled Notes in accordance with its applicable procedures (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes shall be delivered to the Issuer following a written request from the Issuer. The Issuer may not issue new Notes to replace Notes that it

has paid or that have been delivered to the Trustee for cancellation. So long as any Notes are listed on the Irish Stock Exchange and admitted for trading on the Global Exchange Market and the rules and regulations of the Irish Stock Exchange so require, the Issuer undertakes to promptly inform the Irish Stock Exchange on any such cancellation.


Section .	Defaulted Interest.

If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, which special record date shall be the fifteenth day next preceding the date fixed by the Issuer for payment, in each case at the rate provided in the Notes and in Section 4.01. The Issuer shall notify the Trustee and Paying Agent as soon as practicable in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuer shall fix or cause to be fixed each such special record date and payment date, provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer at least five Business Days or shorter period as may be agreed with the Trustee prior to when such notice is to be sent, the Trustee in the name and at the expense of the Issuer) shall deliver to the Holders in accordance with Section 12.01 a notice that states the special record date, the related payment date and the amount of such interest to be paid. So long as any Notes are listed on the Irish Stock Exchange and admitted for trading on the Global Exchange Market and the rules and regulations of the Irish Stock Exchange so require, the Issuer undertakes to promptly inform the Irish Stock Exchange of any such special record date.


Section .	Further Issues.

(a)The Notes may be issued in one or more series. All Notes of any one series shall be substantially identical except as to denomination.

(b)Subject to compliance with Section 4.09, the Issuer may from time to time issue further notes (the “Additional Notes”) as part of a new or existing series of Notes ranking pari passu with the Notes, and with substantially the same terms as to status, redemption and otherwise as such Notes (save for payment of interest accruing prior to the issue date of such Additional Notes or for the first payment of interest following the issue date of such Additional Notes). The Additional Notes will be consolidated and treated as a single class for all purposes under this Indenture, including, without limitation, waivers, amendments, redemptions, and offers to purchase, except as otherwise specified in respect to each series of Notes.

(c)Whenever it is proposed to create and issue any Additional Notes, the Issuer shall give to the Trustee not less than 3 days’ notice in writing of its intention so to do stating the amount of Additional Notes proposed to be created and issued.


Section .	CUSIP, ISIN or Common Code Number.

The Issuer in issuing the Notes may use a “CUSIP”, “ISIN” or “Common Code” number and, if so, such CUSIP, ISIN or Common Code number shall be included in notices of redemption or exchange as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP, ISIN or Common Code number printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or exchange shall not be affected by any defect in or omission of such numbers.

The Issuer will promptly notify the Trustee in writing of any change in the CUSIP, ISIN or Common Code number.


Section .	Deposit of Moneys

No later than 10:00 a.m. (New York time), on February 1 and August 1 of each year, the maturity date of the Notes, each payment date relating to a Change of Control Offer and any payment date in connection with any payment that may be made pursuant to Section 2.12, and on the Business Day immediately following any acceleration of the Notes pursuant to Section 6.02, the Issuer shall deposit with the Paying Agent, in immediately available funds, money in U.S. dollars sufficient to make cash payments, if any, due on such day or date, as the case may be. Subject to receipt of such funds as provided by this Section 2.15 by the Paying Agent, such Paying Agent shall remit such payment in a timely manner to the Holders on such day or date, as the case may be, to the Persons and in the manner set forth in paragraph 2 of the Notes. The Issuer shall promptly notify the Trustee and the Paying Agent in writing of its failure to so act. No Agent shall be obliged to make payment to Holders until such time as it has received such funds.


ARTICLE 5

ARTICLE 6REDEMPTION AND PREPAYMENT


Section .	Notices to Trustee.

If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07, it shall deliver to the Trustee in accordance with Section 12.01, at least 30 days but not more than 60 days before a redemption date, an Officer’s Certificate setting forth:

(i)the Section of this Indenture pursuant to which the redemption shall occur;

(ii)the redemption date and the record date;

(iii)the principal amount of Notes to be redeemed;

(iv)the redemption price; and

(v)the CUSIP, ISIN or Common Code numbers of the Notes, as applicable.


Section .	Selection of Notes to Be Redeemed or Purchased.

If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption on a pro rata basis (or, in the case of Notes issued in global form pursuant to Article 2 hereof, based on a method in accordance with DTC’s (or any other applicable depositary’s) procedures) unless otherwise required by law or applicable stock exchange or Depositary requirements. The Trustee shall not be liable for selections made by it in accordance with this Section 3.02.

No Notes of $200,000 or less can be redeemed in part. Notices of redemption shall be given to each Holder pursuant to Sections 3.03 and 12.01.

If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount of that Note that is to be redeemed. With respect to Notes that are held in certificated form, a new Note in principal amount equal to the unredeemed portion of the original Note will be issued in the name of the Holder of Notes upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of Notes redeemed.

In relation to Definitive Registered Notes, a new Note in principal amount equal to the unpurchased or unredeemed portion of any Note purchased or redeemed in part will be issued in the name of the Holder thereof upon cancellation of the original Note. On or after any purchase or redemption date, unless the Issuer defaults in payment of the purchase or redemption price, interest shall cease to accrue on Notes or portions thereof tendered for purchase or called for redemption.

The Trustee will promptly notify the Issuer in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in principal amounts of $1,000 or whole multiples of $1,000 in excess thereof (provided that Notes of $200,000 or less may only be redeemed in whole and not in part); except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.


Section .	Notice of Redemption.

(a)At least 30 days but not more than 60 days before a redemption date, the Issuer shall deliver, pursuant to Section 12.01, a notice of redemption to each Holder whose Notes are to be redeemed, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or the satisfaction and discharge of this Indenture pursuant to Articles 8 or 11. If the Trustee is to provide notice to the Holders of Notes on behalf of the Issuer, the Issuer must make such written request to the Trustee no later than 5 Business Days prior to the date that such notice is to be delivered. For Notes which are represented by Global Notes held on behalf of DTC, notices may be given by delivery of the relevant notices to DTC for communication to entitled account holders in substitution for the aforesaid mailing. So long as any Notes are listed on the Irish Stock Exchange and admitted for trading on the Global Exchange Market and the rules and regulations of the Irish Stock Exchange so require, any such notice to the Holders of the relevant Notes shall also be published by

the Issuer in a newspaper having a general circulation in Ireland (which is expected to be the Irish Times) or, to the extent and in the manner permitted by such rules, posted on the official website of the Irish Stock Exchange (▇▇▇.▇▇▇.▇▇) and, in connection with any redemption, the Issuer will notify the Irish Stock Exchange of any change in the principal amount of Notes outstanding. Any redemption or notice may, in the Issuer’s discretion, be subject to the satisfaction of one or more conditions precedent.

(b)The notice shall identify the Notes to be redeemed and corresponding CUSIP, ISIN or Common Code numbers, as applicable, and shall state:

(i)the redemption date;

(ii)the redemption price and the amount of accrued interest, if any, and Additional Amounts, if any, to be paid;

(iii)if any Global Note is being redeemed in part, the portion of the principal amount of such Global Note to be redeemed and that, after the redemption date upon surrender of such Global Note, the principal amount thereof will be decreased by the portion thereof redeemed pursuant thereto;

(iv)if any Definitive Registered Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed, and that, after the redemption date, upon surrender of such Note, a new Definitive Registered Note or Definitive Registered Notes in principal amount equal to the unredeemed portion thereof shall be issued in the name of the Holder thereof upon cancellation of the Definitive Registered Note;

(v)the name and address of the Paying Agent(s) to which the Notes are to be surrendered for redemption;

(vi)that Notes called for redemption must be surrendered to the relevant Paying Agent to collect the redemption price, plus accrued and unpaid interest, if any, and Additional Amounts, if any;

(vii)that, unless the Issuer defaults in making such redemption payment, interest, and Additional Amounts, if any, on Notes called for redemption cease to accrue on and after the redemption date, subject to any conditions set out in the notice of redemption;

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

(ix)that no representation is made as to the correctness or accuracy of the CUSIP, ISIN or Common Code numbers, if any, listed in such notice or printed on the Notes.

(c)At the Issuer’s request at least five Business Days prior to the date that such notice of redemption is to be sent (or such shorter period as the Trustee in its sole discretion shall determine), the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense in accordance with Section 12.01; provided, however, that the Issuer shall have delivered to the Trustee an Officer’s Certificate requesting that the Trustee give such notice to each Holder whose Notes are to be redeemed and setting forth the information to be stated in such notice as provided in Section 3.03(b).


Section .	Effect of Notice of Redemption.

Once notice of redemption is given in accordance with Section 3.03 and Section 12.01, Notes called for redemption become due and payable on the redemption date at the redemption price stated in the notice, subject to any conditions set out in the notice of redemption. On and after a redemption date, interest shall cease to accrue on such Notes or portion of them called for redemption, subject to any conditions set out in the notice of redemption. Failure to give notice or any defect in notice to any Holder shall not affect the validity of the notice to any other Holder.


Section .	Deposit of Purchase or Redemption Price.

(a)No later than 10:00 a.m. (New York time) on the purchase or redemption date, the Issuer shall deposit with the Paying Agent (or, if requested by the Trustee, the Trustee) money in U.S. dollars sufficient to pay the redemption price of, and accrued interest, premium and Additional Amounts (if any) on, all Notes to be redeemed or purchased on that date. The Trustee or Paying Agent shall, upon receipt of written instructions, including wire instructions, promptly return to the Issuer any money deposited with the Trustee or Paying Agent, as applicable, by the Issuer in excess of the amounts necessary to pay the redemption price of, accrued interest and Additional Amounts, if any, on, all Notes to be purchased or redeemed. The Trustee or Paying Agent shall inform the Issuer as to the existence of such excess amounts as soon as reasonably practicable after such excess amounts are deposited with the Trustee or Paying Agent.

(b)If the Issuer complies with the provisions of Section 3.05(a), on and after the redemption or purchase date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note

is redeemed or purchased on or after a record date for the payment of interest but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuer to comply with the Section 3.05(a), 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 so paid, in each case at the rate provided in the Notes and Section 4.01.


Section .	Notes Redeemed in Part.

Upon surrender of a Definitive Registered Note that is redeemed in part, the Issuer shall issue and, upon the Issuer’s written request, the Trustee or the Authentication Agent shall authenticate for (and in the name of) the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed portion of the Note surrendered; provided that any Definitive Registered Note shall be in a principal amount of $200,000 or an integral multiple of $1,000 in excess thereof.


Section .	Optional Redemption.

(a)At any time prior to February 1, 2017, the Issuer may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes issued under this Indenture, upon not less than 30 nor more than 60 days’ notice to the Trustee and Holders of Notes, at a redemption price equal to 106.25% of the principal amount of the Notes redeemed, plus accrued and unpaid interest and Additional Amounts, if any, to the redemption date (subject to the rights of Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date), with the net cash proceeds of one or more Equity Offerings; provided that:

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

(ii)such redemption occurs not more than 180 days after the date of the closing of the relevant Equity Offering.

(b)The Issuer may on any one or more occasions redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest and Additional Amounts, if any, to the date of redemption, subject to the rights of Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date.

(c)Except pursuant to subsections (a) and (b) of this Section 3.07 and Section 3.08, the Notes will not be redeemable at the Issuer’s option.


Section .	Redemption Upon Changes in Withholding Taxes.

The Issuer may redeem the Notes, in whole but not in part, at its discretion at any time upon giving not less than 30 nor more than 60 days’ prior notice to the Holders of the Notes (which notice will be irrevocable and given in accordance with the procedures described in Section 3.03 and Section 12.01), at a redemption price equal to the principal amount thereof, together with accrued and unpaid interest, if any, to the date fixed by the Issuer for redemption (a “Tax Redemption Date”) and all Additional Amounts (if any) then due and which will become due on the Tax Redemption Date as a result of the redemption or otherwise (subject to the right of Holders of the Notes on the relevant record date to receive interest due on an interest payment date that is prior to the Tax Redemption Date and Additional Amounts (if any) in respect thereof), if on the next date on which any amount would be payable in respect of the Notes, the Issuer is or would be required to pay Additional Amounts, and the Issuer cannot avoid any such payment obligation by taking reasonable measures available to it (including, for the avoidance of doubt, the designation of a Paying Agent in another jurisdiction), and the requirement arises as a result of:

(i)any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the relevant Tax Jurisdiction affecting taxation, which change or amendment has not been formally proposed before and which becomes effective on or after the Issue Date (or, if the relevant Tax Jurisdiction was not a Tax Jurisdiction on the Issue Date, the date on which such Tax Jurisdiction became a Tax Jurisdiction under this Indenture); or

amendment has not been formally proposed before and becomes effective on or after the Issue Date (or, if the relevant Tax Jurisdiction was not a Tax Jurisdiction on the Issue Date, the date on which such Tax Jurisdiction became a Tax Jurisdiction under this Indenture).

The Issuer will not give any such notice of redemption earlier than 60 days prior to the earliest date on which the Issuer would be obligated to make such payment or withholding if a payment in respect of the Notes were then due, and at the time such notice is given, the obligation to pay Additional Amounts must remain in effect. Prior to the publication or, where relevant, mailing of any notice of redemption of the Notes pursuant to the foregoing, the Issuer will deliver to the Trustee a written opinion of independent tax counsel of recognized standing qualified under the laws of the relevant Tax Jurisdiction, such counsel to be subject to the prior written approval of the Trustee, to the effect that there has been such change or amendment which would entitle the Issuer to redeem the Notes hereunder. In addition, before the Issuer publishes or mails notice of redemption of the Notes as described above, it will deliver to the Trustee an Officer’s Certificate to the effect that the obligation to pay Additional Amounts cannot be avoided by the Issuer taking reasonable measures available to it.

The Trustee will accept such Officer's Certificate and Opinion of Counsel as sufficient evidence of the existence and satisfaction of the conditions precedent as described above, in which event it will be conclusive and binding on the Holders.

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


Section .	Mandatory Redemption.

The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.


Section .	Offer to Purchase by Application of Excess Proceeds.

If, pursuant to Section 4.10 hereof, the Issuer shall be required to commence an Asset Sale Offer (as defined in Section 4.10), it shall follow the procedures specified below.

The Asset Sale Offer shall remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Asset Sale Offer Period”). No later than three Business Days after the termination of the Asset Sale Offer Period (the “Asset Sale Payment Date”), the Issuer shall apply all Excess Proceeds to purchase the principal amount of Notes and the other pari passu Indebtedness required to be purchased pursuant to Section 4.10 hereof (the “Offer Amount”) or, if less than the Offer Amount has been tendered, all Notes and other pari passu Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes and other pari passu Indebtedness so purchased shall be made in the same manner as interest payments are made.

If the Asset Sale Payment Date is on or after a regular record date and on or before the related interest payment date, any accrued and unpaid interest, if any, shall be paid to the Person in whose name a Note is registered at the close of business on such regular record date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

Upon the commencement of an Asset Sale Offer, the Issuer shall send, by first class mail, a notice to the Trustee and each of the Holders. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders.

On or before the Asset Sale Payment Date, the Issuer shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes and other pari passu Indebtedness or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered or less than all of the Notes tendered pursuant to the Asset Sale Offer are accepted for payment by the Issuer for any reason consistent with this Indenture, all Notes and other pari passu Indebtedness tendered or accepted, and shall deliver to the Trustee an Officers’ Certificate stating that such Notes and other pari passu Indebtedness or portions thereof were accepted for

payment by the Issuer in accordance with the terms of this Section 3.10. The Issuer, the Depositary or the Paying Agent, as the case may be, shall promptly (but in any case not later than three Business Days after the termination of the Asset Sale Offer Period) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes properly tendered by such Holder and accepted by the Issuer for purchase, and the Issuer shall promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order from the Issuer shall promptly authenticate and mail (or cause to be transferred by book entity) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered, if any; provided that each Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. Any Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer shall publicly announce the results of the Asset Sale Offer on the Asset Sale Payment Date.

Other than as specifically provided in this Section 3.10, any purchase pursuant to this Section 3.10 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

Section .	Payment of Notes.

No later than 10:00 a.m. (New York time) on a payment date, the Issuer shall pay or cause to be paid the principal of, interest and premium and Additional Amounts, if any, on the Notes in the manner provided in the Notes. Principal, premium, if any, Additional Amounts, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than the Issuer or a Subsidiary thereof, holds as of 10:00 a.m. (New York time) on the due date, money deposited by the Issuer in immediately available funds and designated for and sufficient to pay all principal, premium, Additional Amounts, if any, and interest then due.

Principal of, interest, premium and Additional Amounts, if any, on Global Notes will be payable at the corporate trust office or agency of the Paying Agent maintained in the Borough of Manhattan, City of New York for such purposes and, for as long as any Notes are admitted to trading on the Global Exchange Market and listed on the Irish Stock Exchange in the case of Definitive Notes, at the office of the Paying Agent appointed in London, United Kingdom. All payments on the Global Notes will be made by transfer of immediately available funds to an account of the Holder of the Global Notes in accordance with instructions given by that Holder.

Principal of, interest, premium and Additional Amounts, if any, on any Definitive Registered Notes will be payable at the corporate trust office or agency of any Paying Agent in any location required to be maintained for such purposes pursuant to Section 2.03. In addition, interest on Definitive Registered Notes may be paid by check mailed to the person entitled thereto as shown on the Register for such Definitive Registered Notes.

The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to 1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful. The Issuer shall pay interest (including post‑petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful.


Section .	Maintenance of Office or Agency.

The Issuer shall maintain the offices and agencies specified in Section 2.03. The Issuer shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

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

prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Issuer hereby designates the Corporate Trust Office of the Trustee (the address of which is specified in Section 12.01) as one such office or agency of the Issuer in accordance with Section 2.03.


Section .	Provision of Information.

(a)So long as any Notes are outstanding and whether or not the Issuer is then subject to Section 13(a) or 15(d) of the Exchange Act, the Issuer will furnish to the Trustee:

(i)within 70 days after the end of each of the first three fiscal quarters in each fiscal year, quarterly reports containing unaudited financial statements (including a balance sheet and statement of income, changes in stockholders’ equity and cash flow) for and as of the end of such fiscal quarter and year to date period (with comparable financial statements for the corresponding fiscal quarter and year to date period of the immediately preceding fiscal year);

(ii)within 120 days after the end of each fiscal year, an annual report that includes all information that would be required to be filed with the Commission on Form 20-F (or any successor form) containing the information required to be contained therein for such fiscal year; and

(iii)at or prior to such times as would be required to be filed or furnished to the Commission as a “foreign private issuer” subject to Section 13(a) or 15(d) of the Exchange Act, all such other reports and information that the Issuer would have been required pursuant thereto;

provided, however, that to the extent that the Issuer ceases to qualify as a “foreign private issuer” within the meaning of the Exchange Act, whether or not the Issuer is then subject to Section 13(a) or 15(d) of the Exchange Act, the Issuer will furnish to the Trustee, so long as any notes are outstanding, within 30 days of the respective dates on which the Issuer would be required to file such documents with the Commission if it was required to file such documents under the Exchange Act, all reports and other information that would be required to be filed with (or furnished to) the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act as a “foreign private issuer.”

If required by the rules and regulations of the Commission, the Issuer will electronically file or furnish, as the case may be, a copy of all such information and reports with the Commission for public availability within the time periods specified above. In addition, the Issuer has agreed that, for so long as any notes remain outstanding, it will furnish to the Holders and prospective investors identified by a Holder, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

Notwithstanding the foregoing, the Issuer will be deemed to have furnished such reports referred to in this Section 4.03(a) to the Trustee and the Holders of Notes if the Issuer has filed such reports with the Commission and such reports are publicly available on the Commission’s website; provided, however, that the Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed.

Delivery of such reports, information and documents to the Trustee pursuant to this Section 4.03 is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer's compliance with any of its covenants under this Indenture (as to which the Trustee is entitled to rely exclusively on Officer's Certificates).

(b)So long as any Notes are outstanding, the Issuer will also:

(i)not later than 10 Business Days after furnishing to the Trustee the annual and quarterly reports required by Sections 4.03(a)(i) and (ii), hold a publicly accessible conference call to discuss such reports and the results of operations for the relevant reporting period (including a question and answer portion of the call); and

(ii)issue a press release to an internationally recognized wire service no fewer than three Business Days prior to the date of the conference call required by Section 4.03(b)(i), announcing the time and date of such conference call and either including all information necessary to access the call or directing Holders of the Notes, prospective investors, broker dealers and securities analysts to contact the appropriate person at the Issuer to obtain such information.

(c)At any time that any of the Issuer’s Subsidiaries that are Significant Subsidiaries are Unrestricted Subsidiaries, then the quarterly and annual financial information required by Section 4.03(a) will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, of the financial condition and results of operations of the Issuer and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Issuer, provided that the Issuer will not be required to provide such separate information to the extent such Unrestricted Subsidiaries are the subject of a confidential filing of a registration statement with the Commission.


Section .	Compliance Certificate.

(a)The Issuer shall deliver to the Trustee, within 120 days after the end of each fiscal year (without the need for any request by the Trustee), an Officer’s Certificate stating that a review of the activities of the Issuer and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Issuer has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to such Officer signing such certificate, that to the best of his or her knowledge the Issuer is not (and has not been since the date of the last such certificate, or if none, since the Issue Date) in Default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Issuer is taking or proposes to take with respect thereto).

(b)The Issuer shall, so long as any of the Notes are outstanding, deliver to the Trustee, promptly, in any case within 30 days, upon any Officer becoming aware of any Default or Event of Default, an Officer’s Certificate specifying such Default or Event of Default and what action the Issuer is taking or proposes to take with respect thereto.


Section .	Taxes.

The Issuer shall pay, and shall cause each of its Subsidiaries to pay, within the time period allowed without incurring penalties, all material Taxes, fees, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.


Section .	Stay, Extension and Usury Laws.

The Issuer 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 the Issuer (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.


Section .	Limitation on Restricted Payments.

(a)The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, take any of the following actions (each of which is a “Restricted Payment” and which are collectively referred to as “Restricted Payments”):

(I)declare or pay any dividend on or make any distribution (whether made in cash, securities or other property) with respect to any of the Issuer’s or any Restricted Subsidiary’s Capital Stock (including, without limitation, any payment in connection with any merger or consolidation involving the Issuer or any Restricted Subsidiary) (other than (A) to the Issuer or any Restricted Subsidiary or (B) to all holders of Capital Stock of such Restricted Subsidiary on a pro rata basis or on a basis that results in the receipt by the Issuer or a Restricted Subsidiary of dividends or distributions of greater value than the Issuer or such Restricted Subsidiary would receive on a pro rata basis), except for dividends or distributions payable solely in shares of the Issuer’s Qualified Capital Stock or in options, warrants or other rights to acquire such shares of Qualified Capital Stock;

(II)purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation), directly or indirectly, any shares of the Issuer’s Capital Stock or any Capital Stock of any direct or indirect parent company of the Issuer held by persons other than the Issuer or a Restricted Subsidiary or any options, warrants or other rights to acquire such shares of Capital Stock;

(IV)make any Restricted Investment in any Person.

If any Restricted Payment described above is not made in cash, the amount of the proposed Restricted Payment will be the Fair Market Value of the asset to be transferred as of the date of transfer.

(b)Notwithstanding Section 4.07(a), the Issuer or any Restricted Subsidiary may make a Restricted Payment if, at the time of and after giving pro forma effect to such proposed Restricted Payment:

(A)an amount equal to 100% of Consolidated EBITDA of the Issuer for the period (taken as one accounting period) from the beginning of the fiscal quarter commencing immediately prior to the Issue Date to the end of the Issuer’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated EBITDA for such period is a deficit, less 100% of such deficit), less the product of 1.5 times the Consolidated Net Interest Expense for such period; plus

(B)100% of the aggregate net cash proceeds and the Fair Market Value of marketable securities received by the Issuer since the Issue Date as a contribution to its common equity capital or from the issue or sale of Qualified Capital Stock of the Issuer or from the issue or sale of convertible or exchangeable Redeemable Capital Stock of the Issuer or convertible or exchangeable debt securities of the Issuer, in each case that have been converted into or exchanged for Capital Stock of the Issuer (other than (x) Capital Stock and convertible or exchangeable Redeemable Capital Stock or debt securities sold to a Subsidiary of the Issuer and (y) Capital Stock sold pursuant to the IPO-Related Transactions); plus

(C)(x) in the case of any Restricted Investment that is sold, disposed of or otherwise cancelled, liquidated or repaid, constituting a Restricted Payment made after the date of this Indenture, an amount equal to 100% of the aggregate amount received in cash and the Fair Market Value of the property and marketable securities received by the Issuer or any Restricted Subsidiary, and (y) in the case of the redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary or in the case of an Unrestricted Subsidiary that is merged or consolidated into the Issuer or a Restricted Subsidiary or the assets are transferred to the Issuer or a Restricted Subsidiary (as long as the redesignation of such Subsidiary as an Unrestricted Subsidiary was deemed a Restricted Payment), the Fair Market Value of the Issuer’s interest in such Subsidiary as of the date of such redesignation or at the time of such merger, consolidation or transfer of assets; plus

(D)to the extent that any Restricted Investment constituting a Restricted Payment that was made after the Issue Date is made in an entity that subsequently becomes a Restricted Subsidiary, the Fair Market Value of such Restricted Investment of the Issuer and its Restricted Subsidiaries as of the date such entity becomes a Restricted Subsidiary; plus

(E)100% of any dividends or distributions received by the Issuer or a Restricted Subsidiary after the Issue Date from an Unrestricted Subsidiary, to the extent that such dividends or distributions were not otherwise included in the Consolidated Adjusted Net Income of the Issuer for such period.

(c)Notwithstanding Sections 4.07(a) and 4.07(b), the Issuer and any Restricted Subsidiary may take the following actions:

(i)the payment of any dividend within 60 days after the date of its declaration if at such date of its declaration such payment would have been permitted by the provisions of this covenant;

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

(iv)transfer any of its properties or assets to the Issuer or any other Restricted Subsidiary;

provided that (A) the priority of any preferred stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on common stock and (B) the subordination of (including the application of any standstill period to) loans or advances made to the Issuer or any Restricted Subsidiary to other Indebtedness incurred by the Issuer or any Restricted Subsidiary, shall not be deemed to constitute such an encumbrance or restriction.

(b)Section 4.08(a) will not apply to encumbrances or restrictions existing under or by reason of:

(i)the Notes (including Additional Notes), this Indenture, the Senior Credit Facilities and the security documents related thereto or by other indentures or agreements governing other Indebtedness incurred by the Issuer ranking equally with the Notes; provided that the encumbrances or restrictions imposed by such other indentures or agreements are not materially more restrictive, taken as a whole, than the encumbrances or restrictions imposed by this Indenture;

(ii)any agreements with respect to Indebtedness of the Issuer or any Restricted Subsidiary permitted to be incurred subsequent to the Issue Date pursuant to Section 4.09 and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that such encumbrances or restrictions are not materially less favorable, taken as a whole, to the Holders of the Notes than is customary in comparable financings (as determined in good faith by the Board of Directors or a member of senior management of the Issuer);

(iii)any agreement in effect on the Issue Date and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the Issue Date (as determined in good faith by the Board of Directors or a member of senior management of the Issuer);

(iv)customary non-assignment and similar provisions in contracts, leases and licenses entered into in the ordinary course of business;

(v)any agreement or other instrument of a Person (including its Subsidiaries), acquired by the Issuer or any Restricted Subsidiary in effect at the time of such acquisition (but not created in contemplation thereof), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired (including its Subsidiaries);

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

(xi)purchase money obligations and mortgage financings for property acquired in the ordinary course of business and Capitalized Lease Obligations that impose restrictions on the property purchased or leased of the nature described in Section 4.08(a)(iv); and

(xii)any agreement that extends, renews, amends, modifies, restates, supplements, refunds, refinances or replaces the agreements containing the encumbrances or restrictions in the foregoing clauses (i) through (xi), or in this clause (xii); provided that the terms and conditions of any such encumbrances or restrictions are not materially less favorable, taken as a whole, to the Holders of the Notes than those under or pursuant to the agreement so extended, renewed, amended, modified, restated, supplemented, refunded, refinanced or replaced.


Section .	Limitation on Indebtedness.

(a)The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt); provided, however, that the Issuer may incur Indebtedness (including Acquired Debt) if the Consolidated Fixed Charge Coverage Ratio for the Issuer’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred at the beginning of such four-quarter period.

(b)Section 4.09(a) will not, however, prohibit the following (collectively, “Permitted Debt”):

(i)the incurrence by the Issuer or any Restricted Subsidiary of additional Indebtedness and letters of credit under Credit Facilities in an aggregate principal amount at any time outstanding under this clause (i)

(with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Issuer and its Restricted Subsidiaries thereunder) not to exceed $200.0 million;

(ii)Indebtedness of the Issuer or any Restricted Subsidiary outstanding on the Issue Date (other than Indebtedness described under clause (ix) of this paragraph) after giving effect to the use of proceeds of the Notes and until such Indebtedness is repaid;

(iii)the incurrence by the Issuer of Indebtedness represented by the Notes issued on the Issue Date;

(iv)the incurrence by the Issuer or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under (A) Section 4.09(a) or (B) clauses (ii), (iii), (iv) or (xvi) of this Section 4.09(b);

(v)the incurrence by the Issuer or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Issuer and any of its Restricted Subsidiaries; provided that:

(A)if the Issuer is the obligor on such Indebtedness, such Indebtedness must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes (except in those jurisdictions or territories where such internal subordination is contrary to law, rule or regulation); and

(B)(x) any subsequent issuance or transfer of Capital Stock of the relevant holder of such debt that results in any such Indebtedness being held by a Person other than the Issuer or a Restricted Subsidiary of the Issuer and (y) any sale or other transfer of any such Indebtedness to a Person that is not either the Issuer or a Restricted Subsidiary of the Issuer, will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Issuer or such Restricted Subsidiary, as the case may be, that is not then permitted by this clause (v);

(vi)guarantees of the Issuer’s Indebtedness or Indebtedness of any Restricted Subsidiary by the Issuer or any Restricted Subsidiary; provided that the Restricted Subsidiary complies with Section 4.13;

(vii)the incurrence by the Issuer or any Restricted Subsidiary of Indebtedness arising from customary agreements providing for guarantees, indemnities or obligations in respect of earnouts or other purchase price adjustments or, in each case, similar obligations, in connection with the acquisition or disposition of any business or assets or Person or any shares of Capital Stock of a Subsidiary, other than guarantees or similar credit support given by the Issuer or any Restricted Subsidiary of Indebtedness incurred by any Person acquiring all or any portion of such assets for the purpose of financing such acquisition; provided that, in the case of dispositions, the maximum aggregate liability in respect of all such Indebtedness permitted pursuant to this clause (vii) will at no time exceed the net proceeds, including non-cash proceeds (the Fair Market Value of such non-cash proceeds being measured at the time received and without giving effect to any subsequent changes in value) actually received from such disposition;

(viii)the incurrence by the Issuer or any Restricted Subsidiary of Indebtedness under Currency Agreements, Interest Rate Agreements or Commodity Hedging Agreements, in each case entered into not for speculative purposes (as determined in good faith by the Board of Directors or a member of senior management of the Issuer) (collectively, “Hedging Obligations”);

(ix)the incurrence by the Issuer or any Restricted Subsidiary of Indebtedness (including, without limitation, Capitalized Lease Obligations, mortgage financings and purchase money obligations) in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (ix), plus (without duplication) all Indebtedness of the Issuer and the Restricted Subsidiaries incurred pursuant to Section 4.09(a) (including any Indebtedness reclassified as having been incurred under Section 4.09(a) pursuant to Section 4.09(h)), not to exceed, on the date of such incurrence, an amount equal to 75% of the Fair Market Value (as determined on the date of such incurrence) of all completed Drilling Units owned by the Issuer and its Restricted Subsidiaries plus 75% of the Fair Market Value of the lease component of any Drilling Units subject to sale and leaseback transactions in favor of the Issuer and its Restricted Subsidiaries, in each case, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom); provided that such Indebtedness is (A) incurred by a Drilling Unit Owner or (B) such Indebtedness is secured by Liens over one or more Drilling Units or the Capital Stock of one or more Drilling Unit Owners and/or such Indebtedness is guaranteed by one or more Drilling Unit Owners;

(x)the incurrence by the Issuer or any Restricted Subsidiary of Indebtedness (including, without limitation, Capitalized Lease Obligations, mortgage financings and purchase money obligations), in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design or construction of any Drilling Unit in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (x), plus all Indebtedness of the Issuer and the Restricted Subsidiaries incurred pursuant to Section 4.09(a) (including any Indebtedness reclassified as having been incurred under Section 4.09(a) pursuant to Section 4.09(h)), not to exceed, on the date of such incurrence, an amount equal to 75% of the contract price for the acquisition of all uncompleted Drilling Units, as determined on the date on which the Indebtedness was incurred by the Issuer or its Restricted Subsidiaries, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom);

(xi)the incurrence by the Issuer or any Restricted Subsidiary of Indebtedness in relation to (A) regular or extraordinary maintenance required on any of the Drilling Units owned by the Issuer or any of its Restricted Subsidiaries, (B) scheduled dry-docking of any of the Drilling Units owned by the Issuer or any of its Restricted Subsidiaries and (C) expenditures in connection with inspections, appraisals, repairs, modifications, additions, permits and licenses as may be required from time to time under drilling and other vessel employment contracts of the Issuer or any of its Restricted Subsidiaries or applicable law, rule or regulation, in each case of (A) through (C) above, in the ordinary course of business and in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (xi), at any time outstanding not to exceed $50.0 million;

(xii)the incurrence by the Issuer or any Restricted Subsidiary of Indebtedness through the provision of bonds, guarantees, letters of credit or similar instruments required by the United States Federal Maritime Commission or any other governmental or regulatory agencies, foreign or domestic, including, without limitation, customs authorities; in each case, for Drilling Units owned, operated or chartered by, or in the ordinary course of business of, the Issuer or any of its Restricted Subsidiaries;

(xiii)the incurrence by the Issuer or any of its Restricted Subsidiaries of Indebtedness in the form of customer deposits and advance payments received in the ordinary course of business from customers for services purchased in the ordinary course of business;

(xiv)the incurrence by the Issuer or any Restricted Subsidiary of Indebtedness in respect of workers’ compensation and claims arising under similar legislation, captive insurance companies, or pursuant to self-insurance obligations and not in connection with the borrowing of money or the obtaining of advances or credit;

(xv)the incurrence by the Issuer or any Restricted Subsidiary of Indebtedness arising from (A) the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds in the ordinary course of business; provided that such Indebtedness is extinguished within five Business Days of incurrence, (B) bankers’ acceptances, performance, surety, judgment, appeal or similar bonds, instruments or obligations, (C) completion guarantees or performance or appeal bonds provided or letters of credit obtained by the Issuer or any Restricted Subsidiary in the ordinary course of business, (D) VAT or other tax guarantees in the ordinary course of business, (E) the financing of insurance premiums in the ordinary course of business and (F) any customary cash management, cash pooling or netting or setting off arrangements;

(xvi)Indebtedness of any Person incurred and outstanding on the date on which such Person becomes a Restricted Subsidiary of the Issuer or is merged, consolidated, amalgamated or otherwise combined with (including pursuant to any acquisition of assets and assumption of related liabilities) the Issuer or any Restricted Subsidiary (other than Indebtedness incurred (A) to provide all or any portion of the funds used to consummate the transaction or series of related transactions pursuant to which such Person became a Restricted Subsidiary or was otherwise acquired by the Issuer or a Restricted Subsidiary or (B) otherwise in connection with or contemplation of such acquisition); provided, however, with respect to this clause (xvi), that at the time of such acquisition or other transaction pursuant to which such Indebtedness is deemed to be incurred, (x) the Issuer could incur at least $1.00 of additional Indebtedness under Section 4.09(a), after giving pro forma effect to such acquisition or other transaction or (y) the Consolidated Fixed Charge Coverage Ratio would not be less than it was immediately prior to giving effect to such acquisition or other transaction; and

(xvii)the incurrence by the Issuer or any Restricted Subsidiary of Indebtedness (other than and in addition to Indebtedness permitted under clauses (i) through (xvi) above) in an aggregate principal amount at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, replace, refinance, defease or discharge any Indebtedness incurred pursuant to this clause (xvii), not to exceed $100.0 million.

Accrual of interest or dividends, the accretion of accreted value, the accretion or amortization of original issue discount, the obligation to pay commitment fees, the reclassification of preferred stock as Indebtedness due to a change in accounting principles and the payment of interest or dividends in the form of additional Indebtedness or in the form of additional shares of the same class will not be deemed to be an incurrence of Indebtedness for purposes of this Section 4.09.

(c)The Issuer will not incur any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Issuer unless such Indebtedness is also contractually subordinated in right of payment to the Notes on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Issuer solely by virtue of being unsecured or by virtue of being secured with different collateral or by virtue of being secured on a junior priority basis or by virtue of the application of waterfall or other payment ordering provisions affecting different tranches of Indebtedness under Credit Facilities.

(d)For purposes of determining compliance with any restriction on the incurrence of Indebtedness in dollars where Indebtedness is denominated in a different currency, the amount of such Indebtedness will be the Dollar Equivalent determined on the date of such determination; provided that if any such Indebtedness denominated in a different currency is subject to a Currency Agreement (with respect to dollars) covering principal amounts payable on such Indebtedness, the amount of such Indebtedness expressed in dollars will be adjusted to take into account the effect of such agreement. The principal amount of any Permitted Refinancing Indebtedness incurred in the same currency as the Indebtedness being refinanced will be the Dollar Equivalent of the Indebtedness refinanced determined on the date such Indebtedness being refinanced was initially incurred, except to the extent that such Dollar Equivalent was determined based on a Currency Agreement (with respect to dollars), in which case the amount of such Permitted Refinancing Indebtedness will be adjusted to take into account the effect of such agreement. Notwithstanding any other provision of this covenant, for purposes of determining compliance with this Section 4.09, increases in Indebtedness solely due to fluctuations in the exchange rates of currencies or currency values will not be deemed to exceed the maximum amount that the Issuer or a Restricted Subsidiary may incur under this Section 4.09.

(e)For purposes of determining any particular amount of Indebtedness under this Section 4.09:

(i)obligations with respect to letters of credit, guarantees or Liens, in each case supporting Indebtedness otherwise included in the determination of such particular amount will not be included; and

(ii)any Liens granted pursuant to the equal and ratable provisions referred to in Section 4.12 will not be treated as Indebtedness.

(f)The amount of any Indebtedness outstanding as of any date will be:

(i)in the case of any Indebtedness issued with original issue discount, the amount of the liability in respect thereof determined in accordance with U.S. GAAP;

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

(iii)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.

(g)If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be Incurred by a Restricted Subsidiary of the Issuer as of such date (and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09, the Restricted Subsidiary shall be in Default of this Section 4.09).

(h)For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Indebtedness described in this Section 4.09, the Issuer, in its sole discretion, will be permitted to classify such item of Indebtedness on the date of its incurrence and only be required to include the amount and type of such Indebtedness in one of such clauses and will be permitted on the date of such incurrence to divide and classify an item of Indebtedness in more than one of the types of Indebtedness described in

Sections 4.09(a) and (b), and from time to time to reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09, provided that (i) Indebtedness incurred pursuant to Section 4.09(b)(i) and 4.09(b)(ix) may not be reclassified and (ii) Indebtedness incurred pursuant to Section 4.09(b)(x) shall be automatically reclassified to Section 4.09(b)(ix) upon completion of the relevant Drilling Unit. Indebtedness under the Senior Credit Facilities outstanding on the Issue Date will be deemed to have been incurred on such date in reliance on the exception provided in Section 4.09(b)(ix).


Section .	Asset Sales.

(a) The Issuer will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: (i) the Issuer (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Capital Stock issued or sold or otherwise disposed of; (ii) for the purposes of this provision, the fair market value is determined by (a) an executive Officer of the Issuer if the value is less than $20.0 million and evidenced by an Officer's Certificate delivered to the Trustee; or (b) the Issuer’s Board of Directors if the value is $20.0 million or more and evidenced by a resolution of such Board of Directors delivered to the Trustee; and (iii) at least 75% of the consideration received in the Asset Sale by the Issuer or such Restricted Subsidiary is in the form of cash, or Cash Equivalents, or any combination thereof.

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

(i) any Indebtedness or other liabilities, as shown on the Issuer’s or such Restricted Subsidiary’s most recent consolidated balance sheet or the notes thereto, of the Issuer or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Restricted Subsidiary’s Guarantee) that are assumed, repaid or retired by the transferee (or a third party on behalf of the transferee) of any such assets;

(ii) any securities, notes or other obligations received by the Issuer or any such Restricted Subsidiary from such transferee that are converted, sold or exchanged by the Issuer or such Restricted Subsidiary into cash or Cash Equivalents within 365 days following the closing of such Asset Sale, to the extent of the cash or Cash Equivalents received in that conversion, sale or exchange; and

(iii) the Fair Market Value of (x) any assets (other than securities and other assets that are classified as current assets under GAAP) received by the Issuer or any Restricted Subsidiary to be used by the Issuer or a Restricted Subsidiary in a Permitted Business (y) Capital Stock in a Person that is a Restricted Subsidiary or a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the acquisition of such Person by the Issuer or a Restricted Subsidiary or a (z) a combination of (x) and (y).

(c) Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Issuer may apply those Net Proceeds at its option:

(i) to repay, purchase, repurchase, redeem, defease or otherwise acquire or retire Senior Debt of the Issuer (including the notes offered hereby) or any Indebtedness of a Restricted Subsidiary;

(ii) to acquire all or substantially all of the assets of, or a majority of the Voting Stock of a Person engaged in a Permitted Business, or to acquire Voting Stock constituting a minority interest in any Person that at such time is a Restricted Subsidiary;

(iii) to make a capital expenditure in a Permitted Business;

(iv) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business; or

(v) any combination of the transactions permitted by the foregoing clauses (i) through (iv).

A binding contract to apply Net Proceeds in accordance with clauses (ii) through (iv) above (including, without limitation, pursuant to a Drilling Unit Construction Contract, memorandum of agreement to purchase a Drilling Unit

or an exercised Drilling Unit Purchase Option Contract) will toll the 365-day period in respect of such Net Proceeds for a period not to exceed 365 days from the expiration of the aforementioned 365-day period, provided that such binding contract shall be treated as a permitted application of Net Proceeds from the date of such binding contract until and only until the earliest of (x) the date on which such acquisition or expenditure is consummated and (y) in the case of any Drilling Unit Construction Contract, memorandum of agreement to purchase a Drilling Unit or any exercised Drilling Unit Purchase Option Contract, the date of expiration or termination of such Drilling Unit Construction Contract, memorandum of agreement to purchase a Drilling Unit or exercised Drilling Unit Purchase Option Contract and (z) in all cases, the 365th day following the expiration of the aforementioned initial 365-day period (clauses (x), (y) or (z) as applicable, the “Reinvestment Termination Date”). If such acquisition or expenditure or acquisition in connection with a Drilling Unit Construction Contract, memorandum of agreement to purchase a Drilling Unit or exercised Drilling Unit Purchase Option Contract is not consummated on or before the Reinvestment Termination Date and the Issuer (or the applicable Restricted Subsidiary, as the case may be) shall not have applied such Net Proceeds pursuant to clauses (i) through (v) of Section 4.10(c) on or before the Reinvestment Termination Date, such transaction shall be deemed not to have been a permitted application of the Net Proceeds. Pending the final application of any Net Proceeds, the Issuer may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture.

(d) 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 $50.0 million, the Issuer will make an offer (an “Asset Sale Offer”) to all Holders of Notes and, to the extent the Issuer is legally required to do so, to all holders of other Indebtedness of the Issuer that is pari passu with the Notes, to purchase the maximum principal amount of Notes (in integral multiples of $1,000) and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount of Notes and other pari passu Indebtedness so included and to be purchased or the lesser amount required under agreements governing such other pari passu Indebtedness so included, plus accrued and unpaid interest, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Issuer may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness so included tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other pari passu Indebtedness so included to be purchased on a pro rata basis (or, in the case of Notes issued in global form, based on a method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection unless otherwise required by law). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

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

(f) The provisions of Section 4.10 may be waived or modified with the consent of the Holders of a majority in principal amount of the Notes.


Section .	Limitation on Transactions with Affiliates.

(a)The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, enter into any transaction or series of related transactions (including, without limitation, the sale, purchase, exchange or lease of assets or property or the rendering of any service), with, or for the benefit of, any Affiliate of the Issuer or any Restricted Subsidiary’s Affiliate involving aggregate payments or consideration in excess of $5.0 million unless:

(i)such transaction or series of transactions is on terms that, taken as a whole, are not materially less favorable to the Issuer or such Restricted Subsidiary, as the case may be, than those that could have been obtained in a comparable arm’s length transaction with third parties that are not Affiliates (as determined in good faith by the Board of Directors or a member of senior management of the Issuer);

(ii)with respect to any transaction or series of related transactions involving aggregate payments or the transfer of assets or provision of services, in each case having a value greater than $25.0 million, the Issuer will obtain a resolution of its Board of Directors certifying that such transaction complies with clause (a) above and that the fairness of such transaction has been approved by a majority of the Disinterested Directors (or in the event there is only one Disinterested Director, by such Disinterested Director) of the Issuer’s Board of Directors; and

(iii)in the case that there are no Disinterested Directors or with respect to any transaction or series of related transactions involving aggregate payments or the transfer of assets or the provision of services, in each case having a value greater than $50.0 million, the Issuer will obtain a written opinion of an accounting, appraisal, investment banking or advisory firm of international standing, or other recognized independent expert of international standing with experience appraising the terms and conditions of the type of transaction or series of related transactions for which an opinion is required, stating that the transaction or series of transactions is (A) fair to the Issuer or such Restricted Subsidiary from a financial point of view taking into account all relevant circumstances or (B) on terms not less favorable than might have been obtained in a comparable transaction at such time on an arm’s length basis from a Person who is not an Affiliate.

(b)Notwithstanding the foregoing, the restrictions set forth in Section 4.11(a) will not apply to:

(i)customary directors’ fees, indemnification and similar arrangements (including the payment of directors’ and officers’ insurance premiums), consulting fees, employee salaries, bonuses, employment agreements and arrangements, compensation or employee benefit arrangements, including stock options or legal fees (as determined in good faith by the Board of Directors or a member of senior management of the Issuer);

(ii)any employment agreement, collective bargaining agreement, consultant, employee benefit arrangements with any employee, consultant, officer or director of the Issuer or any Restricted Subsidiary, including under any stock option, stock appreciation rights, stock incentive or similar plans, entered into in the ordinary course of business;

(iii)any Restricted Payments not prohibited by Section 4.07 and Permitted Investments;

(iv)transactions pursuant to, or contemplated by any agreement or arrangement in effect on the Issue Date and transactions pursuant to any amendment, modification, supplement or extension thereto; provided that any such amendment, modification, supplement or extension to the terms thereof is not more materially disadvantageous to the Holders of the Notes than the original agreement or arrangement as in effect on the Issue Date;

(v)transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Issuer solely because the Issuer owns, directly or through a Restricted Subsidiary, Capital Stock in, or controls, such Person;

(vi)transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture that are fair to the Issuer or the Restricted Subsidiaries or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated Person, in each case, as determined in good faith by the Board of Directors or a member of senior management of the Issuer;

(vii)the payment of reasonable fees and indemnities to employees, officers and directors of the Issuer and its Restricted Subsidiaries in the ordinary course of business;

(viii)any issuance of Redeemable Capital Stock of the Issuer to Affiliates of the Issuer which is permitted under Section 4.09;

(ix)the granting and performance of registration rights for the Issuer’s and its Restricted Subsidiaries’ securities;

(x)issuances or sales of Qualified Capital Stock of the Issuer;

(xi)Management Advances; and

(xii)transactions between or among the Issuer and the Restricted Subsidiaries or between or among Restricted Subsidiaries.


Section .	Limitation on Liens.

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind (except for Permitted Liens) securing Indebtedness upon any of their property or assets, whether owned at or acquired after the Issue Date unless:

(a)in the case of any Lien securing Subordinated Indebtedness, the Issuer’s obligations in respect of the Notes are directly secured by a Lien on such property, assets or proceeds that is senior in priority to the Lien securing the Subordinated Indebtedness until such time as the Subordinated Indebtedness is no longer secured by a Lien; and

(b)in the case of any other Lien, the Issuer’s obligations in respect of the Notes and all other amounts due under this Indenture are equally and ratably secured with the obligation or liability secured by such Lien until such time as such obligations are no longer secured by a Lien.


Section .	Limitation on Guarantees of Indebtedness by Restricted Subsidiaries.

(a)The Issuer will not permit any Restricted Subsidiary, directly or indirectly, to guarantee, assume or in any other manner become liable for the payment of any Indebtedness of the Issuer or any Restricted Subsidiary, unless:

(i)such Restricted Subsidiary simultaneously executes and delivers a supplemental indenture to this Indenture providing for a Guarantee of payment of the Notes by such Restricted Subsidiary on the same terms as the guarantee of such Indebtedness; and

(ii)with respect to any guarantee of Subordinated Indebtedness by such Restricted Subsidiary, any such guarantee shall be subordinated to such Restricted Subsidiary’s Guarantee with respect to the Notes at least to the same extent as such Subordinated Indebtedness is subordinated to the Notes.

(b)The restrictions of Section 4.13(a) will not be applicable to any guarantees of any Restricted Subsidiary:

(i)existing on the date of this Indenture;

(ii)of Indebtedness of the Issuer or any Restricted Subsidiary incurred pursuant to clauses 4.09(b)(ix) and (x);

(iii)that existed at the time such Person became a Restricted Subsidiary if the guarantee was not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary;

(iv)arising solely due to the granting of a Permitted Lien that would not otherwise constitute a guarantee of Indebtedness of the Issuer; or

(v)given to a bank or trust company having combined capital and surplus and undivided profits of not less than $500.0 million, whose debt has a rating, at the time such guarantee was given, of at least A or the equivalent thereof by S&P and at least A2 or the equivalent thereof by ▇▇▇▇▇’▇, in connection with the operation of cash management programs established for the Issuer’s benefit or that of any Restricted Subsidiary.

(c)In addition, notwithstanding anything to the contrary herein:

(i)no Guarantee of the Notes shall be required if such Guarantee could reasonably be expected to give rise to or result in (A) personal liability for the officers, directors or shareholders of such Restricted Subsidiary and (B) any violation of applicable law that cannot be avoided or otherwise prevented through measures reasonably available to the Issuer or such Restricted Subsidiary; and

(ii)each such Guarantee may be limited as necessary to recognize certain defenses generally available to guarantors (including those that relate to fraudulent conveyance or transfer, voidable preference, financial assistance, corporate purpose, capital maintenance or similar laws, regulations or defenses affecting the rights of creditors generally) or other considerations under applicable law.

(d)A Guarantor’s Guarantee (and the Guarantee, if any, of any Subsidiary of such Guarantor) will be automatically and unconditionally released (and thereupon shall terminate and be discharged and be of no further force and effect):

(i)upon any sale or disposition of (A) Capital Stock of a Guarantor (or any parent entity thereof) following which such Guarantor is no longer a Restricted Subsidiary or (B) all or substantially all the properties and assets of a Guarantor (including by way of merger or consolidation), in each of (A) and (B) to a Person that is not (either before or after giving effect to such transaction) the Issuer or a Restricted Subsidiary;

(ii)upon the designation of such Guarantor (or any parent entity thereof) as an Unrestricted Subsidiary;

(iii)if such Guarantor is unconditionally released and discharged from its liability with respect to Indebtedness in connection with which such guarantee was executed pursuant to this Section 4.13;

(iv)upon legal defeasance, covenant defeasance or satisfaction and discharge of this Indenture as provided below under Article 8; and

(v)upon full and final payment of the Notes.


Section .	Offer to Repurchase Upon Change of Control.

(a)If a Change of Control occurs, each Holder of Notes will have the right to require the Issuer to repurchase all or any part (equal to $200,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to an offer by the Issuer (a “Change of Control Offer”) on the terms set forth in this Indenture. In the Change of Control Offer, the Issuer will offer a payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest and Additional Amounts, if any, on the Notes repurchased to the date of purchase (the “Change of Control Payment”), subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date. Unless the Issuer has unconditionally exercised its right to redeem all the Notes as described under Section 3.07 or all conditions to such redemption have been satisfied or waived, within 30 days following any Change of Control, the Issuer will mail a notice to each Holder of the Notes at such Holder’s registered address or otherwise deliver a notice in accordance with the procedures described under Section 3.03 and Section 12.01, stating that a Change of Control Offer is being made and offering to repurchase Notes on the date (the “Change of Control Payment Date”) specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed or delivered, pursuant to the procedures required by the Indenture and described in such notice. Such notice shall also state:

(i)that a Change of Control has occurred, the date it occurred and offering to purchase the Notes on the date specified in the notice;

(ii)a brief summary of the circumstances and relevant facts regarding such Change of Control;

(iii)the Change of Control Purchase Price and the Change of Control Purchase Date, which will be a Business Day no earlier than 30 days nor later than 60 days from the date such notice is mailed, or such later date as is necessary to comply with requirements under the Exchange Act and any applicable securities laws or regulations;

(iv)that any Note accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Purchase Date unless the Change of Control Purchase Price is not paid;

(v)that any Note (or part thereof) not tendered will continue to accrue interest; and

(vi)any other procedures that a Holder of Notes must follow to accept a Change of Control Offer or to withdraw such acceptance.

The Issuer will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws and regulations to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of this Indenture, the Issuer will comply with any applicable securities laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of such compliance.

(b)On the Change of Control Payment Date, the Issuer will, to the extent lawful:

(i)accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

(ii)deposit with the Principal Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(iii)deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer.

(c)The Principal Paying Agent will promptly mail (or cause to be delivered) to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee (or its authenticating agent) will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(d)The provisions of this Section 4.14 that require the Issuer to make a Change of Control Offer following a Change of Control will be applicable whether or not any other provisions of this Indenture are applicable.

(e)The Issuer will not be required to make a Change of Control Offer upon a Change of Control if (i) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all

Notes properly tendered and not withdrawn under the Change of Control Offer, or (ii) a notice of redemption has been given pursuant to Section 3.03 and Section 3.07, unless and until there is a default in payment of the applicable redemption price.

(f)Notwithstanding anything to the contrary contained herein, (i) 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 and (ii) the Issuer shall not be required to make any Change of Control Offer in the event of a recapitalization to the extent not otherwise a Change of Control.

(g)If and for so long as the Notes are listed on the Irish Stock Exchange and admitted to trading on the Global Exchange Market and the rules and regulations of the Irish Stock Exchange so require, the Issuer will publish a public announcement with respect to the results of any Change of Control Offer in a leading newspaper of general circulation in Ireland (which is expected to be the Irish Times) or, to the extent and in the manner permitted by such rules, post such notice on the official website of the Irish Stock Exchange (▇▇▇.▇▇▇.▇▇).


Section .	Designation of Unrestricted and Restricted Subsidiaries.

(a)The Board of Directors of the Issuer may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Issuer and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted 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 Issuer. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors of the Issuer may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default.

(b)If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Issuer as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09, the Issuer will be in default of such covenant. The Board of Directors of the Issuer may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (i) such Indebtedness is permitted under Section 4.09, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference period; and (ii) no Default or Event of Default would be in existence following such designation.


Section .	Conduct of Business.

(a)The Issuer will not, and will not permit any of its Restricted Subsidiaries to, engage in the conduct of any business other than a Permitted Business.


Section .	Additional Amounts.

(a)All payments made under or with respect to the Notes (whether or not in the form of Definitive Registered Notes) or any Note Guarantee will be made free and clear of and without withholding or deduction for, or on account of, any present or future 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 (i) any jurisdiction in which the Issuer or any Guarantor (including any successor entity) is then incorporated or organized, engaged in business or resident for tax purposes, or any political subdivision thereof or therein, or (ii) any jurisdiction from or through which payment is made by or on behalf of the Issuer or any Guarantor (including, without limitation, the jurisdiction of any Paying Agent) or any political subdivision thereof or therein (each, a “Tax Jurisdiction”) will at any time be required to be made from any payments made by or on behalf of the Issuer or any Guarantor under or with respect to the Notes or any Note Guarantee, including, without limitation, payments of principal, redemption price, purchase price, interest or premium, the Issuer or the relevant Guarantor, as applicable, will pay such additional amounts (the “Additional Amounts”) as may be necessary in order that the net amounts received in respect of such payments after such withholding or deduction (including any such withholding or deduction from such Additional Amounts) will equal the respective amounts that would have been received in respect of such payments in the absence of such withholding or deduction; provided, however, that no Additional Amounts will be payable with respect to:

(i)any Taxes that would not have been imposed but for the Holder of the Notes having a past or present connection to the relevant Tax Jurisdiction (other than connections resulting from the mere acquisition or holding of any Note or the enforcement of, or receipt of payment under or in respect of, any Note or any Note Guarantee), including, without limitation, being a citizen or resident or national of, or being incorporated in or carrying on a business in, the relevant Tax Jurisdiction in which such Taxes are imposed;

(ii)any Taxes that are imposed or withheld as a result of the failure of the Holder of the Notes to comply with any reasonable written request, made to such Holder in writing at a time that would enable the Holder acting reasonably to comply with such request and, in any event, at least 90 days before any withholding or deduction of such Taxes would be payable, by the Issuer to satisfy any certification, information or other reporting requirement, which is required or imposed by a statute, treaty, regulation or administrative practice of the relevant Tax Jurisdiction as a precondition to any exemption from, or reduction in the rate of deduction or withholding of, Taxes imposed by the Tax Jurisdiction, but in each case, only to the extent such Holder is legally entitled to satisfy such requirements;

(iii)any Taxes imposed or withheld as a result of the presentation of any Note for payment (where Notes are in the form of Definitive Registered Notes and presentation is required) more than 60 days after the relevant payment is first made available for payment to the Holder (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 60 day period);

(iv)any estate, inheritance, gift, sale, transfer, personal property or similar Taxes;

(v)any Taxes withheld or deducted from a payment to an individual as required pursuant to European Council Directive 2003/48/EC or any other directive implementing the conclusions of the ECOFIN Council meetings of November 26, 2000 and November 27, 2000 on the taxation of savings income or any law implementing or complying with or introduced in order to conform to, such Directive;

(vi)any Taxes imposed or withheld as a result of the presentation of any Note for payment by or on behalf of a Holder of Notes who would have been able to avoid such withholding or deduction by presenting the relevant Note to another Paying Agent in a member state of the European Union;

(vii)any Taxes payable other than by deduction or withholding from payments under or with respect to the Note or any Note Guarantee; or

(viii)any combination of items (1) through (7) above.

(b)In addition to the foregoing, the Issuer and the Guarantors will also pay and indemnify the Holders (and Trustee, as applicable) for any present or future stamp, issue, registration, court or documentary Taxes, or any other excise or property Taxes, charges or similar levies or Taxes, which are levied by any Tax Jurisdiction on the execution, delivery, issuance, registration or enforcement of any of the Notes, this Indenture, any Note Guarantee or any other document or instrument referred to therein, or the consummation of the transactions contemplated thereby or the receipt of any payments with respect thereto.

(c)If the Issuer or any Guarantor, as the case may be, becomes aware that it will be obligated to pay Additional Amounts with respect to any payment under or with respect to the Notes or any Note Guarantee, the Issuer or the relevant Guarantor will deliver to the Trustee on a date that is at least 45 days prior to the date of that payment (unless the obligation to pay Additional Amounts arises after the 45th day prior to that payment date, in which case the Issuer or the relevant Guarantor shall notify the Trustee promptly thereafter) an Officer’s Certificate stating the fact that Additional Amounts will be payable and the amount estimated to be so payable. The Officer’s Certificate must also set forth any other information reasonably necessary to enable the Paying Agents to pay Additional Amounts to Holders on the relevant payment date. The Trustee shall be entitled to rely solely on such Officer’s Certificate as conclusive proof that such payments are necessary. Unless and until a Responsible Officer of the Trustee receives such an Officer’s Certificate, the Trustee may assume without inquiry that no Additional Amounts are payable.

(d)The Issuer or the relevant Guarantor will provide the Trustee with documentation reasonably satisfactory to the Trustee evidencing the payment of Additional Amounts. The Issuer or the relevant Guarantor will make all withholdings and deductions required by law and will remit the full amount deducted or withheld to the relevant tax authority in accordance with applicable law. The Issuer or the relevant Guarantor will provide to the Trustee an official receipt or, if official receipts are not obtainable, other documentation reasonably satisfactory to the Trustee evidencing the payment of any Taxes so deducted or withheld. The Issuer or the relevant Guarantor will attach to each certified copy or other document a certificate stating the amount of such Taxes paid per $1,000 principal amount of the Notes then outstanding. Upon request, copies of those receipts or other documentation, as the case may be, will be made available by the Trustee to the Holders of the Notes.

(e)Whenever in this Indenture there is mentioned, in any context, the payment of amounts based upon the principal amount of the Notes or of principal, interest or of any other amount payable under, or with respect to, any of the Notes or any Note Guarantee, 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.

(f)The obligations set forth in this Section 4.17 will survive any termination, defeasance or discharge of this Indenture and any transfer by a Holder or beneficial owner of its Notes.

(g)The obligations set forth in this Section 4.17 will also apply, mutatis mutandis, to any jurisdiction in which any successor Person to the Issuer or any Guarantor is incorporated or organized, engaged in business for tax purposes or otherwise resident for tax purposes and any jurisdiction from or through which any payment under or with respect to the Notes (or any Note Guarantee) is made by or on behalf of such Person, including any department or political subdivision thereof or therein.


Section .	Payments for Consent

The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms of the provisions of the relevant Indenture or Notes unless such consideration is offered to be paid and is paid to all Holders of Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. Notwithstanding the foregoing, the Issuer and its Restricted Subsidiaries shall be permitted, in 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, to exclude Holders of Notes in any jurisdiction where (a)(i) the solicitation of such consent, waiver or amendment, including in connection with an offer to purchase for cash, or (ii) the payment of the consideration therefor would require the Issuer or any of its Restricted Subsidiaries to file a registration statement, prospectus or similar document under any applicable securities laws (including, but not limited to, the U.S. federal securities laws and the laws of the European Union or its members states), which the Issuer in its sole discretion determines (acting in good faith) would be materially burdensome (it being understood that it would not be materially burdensome to file the consent document(s) 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.


Section .	Suspension of Certain Covenants When Notes Rated Investment Grade.

If on any date following the Issue Date, (i) the Notes have an Investment Grade Rating from both of the Rating Agencies and (ii) no Default or Event of Default has occurred and is continuing under this Indenture (the occurrence of the events described in clauses (i) and (ii) of this Section 4.20(a) being collectively referred to as a “Suspension Event”), beginning on the day of the Suspension Event and continuing until such time (the “Suspension Period”), if any, at which the Notes cease to have an Investment Grade Rating from each Rating Agency (the “Reversion Date”), the provisions of Sections 4.07 through 4.11, Section 4.15 and clause 5.01(a)(iii) will not be applicable to the Notes (collectively, the “Suspended Covenants”). Such covenants and any related default provisions will again apply according to their terms on and after the Reversion Date. Such covenants will not, however, be of any effect with regard to actions of the Issuer or the Restricted Subsidiaries properly taken during the Suspension Period, and Section 4.07 will be interpreted as if it had been in effect since the date of this Indenture except that no 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 Section 4.09(b)(ii).


Section .	Maintenance of Listing.

The Issuer shall use commercially reasonable efforts to have the Notes admitted to trading on the Global Exchange Market and listed on the Irish Stock Exchange within a reasonable period after the Issue Date and will maintain such listing as long as the Notes are outstanding; provided that if at any time the Issuer determines that it can no longer reasonably comply with the requirements for listing the Notes on the Global Exchange Market or if maintenance of such listing becomes unduly onerous, it will use its commercially reasonable efforts prior to the delisting of the Notes from the Global Exchange Market and thereafter, to maintain a listing of such Notes on such other “recognised stock exchange” as defined in Section 1005 of the Income Tax ▇▇▇ ▇▇▇▇ of the United Kingdom.

(c)Nothing in this Indenture will prevent any Restricted Subsidiary from, and this Section 5.01 will not apply to any Restricted Subsidiary, consolidating with, merging into or transferring all or substantially all of its properties and assets to the Issuer or any other Restricted Subsidiary.

(d)Section 5.01(a)(iii) will not apply to any sale or other disposition of all or substantially all of the assets or merger or consolidation of the Issuer with or into an Affiliate solely for the purpose of reincorporating the Issuer in another jurisdiction for tax reasons.


Section .	Successor Corporation Substituted.

Upon any consolidation or merger or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the properties or assets of the Issuer or the Restricted Subsidiaries of the Issuer, in a transaction that is subject to, and that complies with the provisions of Section 5.01, the successor Person formed by such consolidation or into or with which the Issuer is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition, the provisions of this Indenture referring to the “Issuer” shall refer instead to the successor Person and not to the Issuer), and may exercise every right and power of the predecessor Issuer under this Indenture with the same effect as if such successor Person had been named as the Issuer herein and the predecessor Issuer shall be discharged from all obligations under the Notes, this Indenture and any supplemental indenture, as applicable; provided, however, that the predecessor Issuer shall not be relieved from the obligation to pay the principal, interest, premium and Additional Amounts (if any) on the Notes except in the case of a sale, conveyance, transfer or lease of all of the assets of or a consolidation or merger of the Issuer in a transaction that is subject to, and that complies with the provisions of, Section 5.01.

Section .	Acceleration.

(a)If an Event of Default specified in clauses (g) or (h) of Section 6.01 occurs and is continuing, then the principal of, premium, if any, and Additional Amounts and accrued and unpaid interest on all the outstanding Notes shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of Notes.

(b)If an Event of Default (other than as specified in clauses (g) or (h) of Section 6.01) occurs and is continuing, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer (and to the Trustee if such notice is given by the Holders) may, and the Trustee, upon the written request of such Holders, shall, declare the principal of, premium, if any, and any Additional Amounts and accrued interest on all the outstanding Notes immediately due and payable, and upon any such declaration all such amounts payable in respect of the Notes will become immediately due and payable.

(c)At any time after a declaration of acceleration under this Indenture, but before a judgment or decree for payment of the money due has been obtained by the Trustee, the Holders of a majority in aggregate principal amount of the outstanding Notes, by written notice to the Issuer and the Trustee, may rescind such declaration and its consequences if:

(i)the Issuer has paid or deposited with the Trustee a sum sufficient to pay:

(A)all overdue interest and Additional Amounts on all Notes then outstanding;

(B)all unpaid principal of and premium, if any, on any outstanding Notes that has become due otherwise than by such declaration of acceleration and interest thereon at the rate borne by the Notes;

(C) to the extent that payment of such interest is lawful, interest upon overdue interest and overdue principal at the rate borne by the Notes; and

(ii)the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and

(iii)all Events of Default, other than the non-payment of amounts of principal of, premium, if any, and any Additional Amounts and interest on the Notes that has become due solely by such declaration of acceleration, have been cured or waived.

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


Section .	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, interest, premium and Additional Amounts, if any, on the Notes or to enforce the performance of any provision of 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.


Section .	Waiver of Past Defaults.

The Holders of not less than a majority in aggregate principal amount of the outstanding Notes may, on behalf of the Holders of all the Notes, waive any past defaults under this Indenture, except a continuing default in the payment of the principal of, premium, if any, and Additional Amounts or interest on any Note held by a non-consenting Holder (which may only be waived with the consent of Holders of Notes holding 90% of the aggregate principal amount of the Notes outstanding under this Indenture).

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 .	Control by Majority.

Holders of a majority in aggregate principal amount of the then outstanding Notes may 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 the Trustee. 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 personal liability.


Section .	Limitation on Suits.

Subject to the provisions of this Indenture relating to the duties of the Trustee, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any Holders of Notes unless such Holders have made a written request and offered to the Trustee indemnity and/or security satisfactory to the Trustee against any loss, liability or expense. Except (subject to Article 9) to enforce the right to receive payment of principal, premium, if any, or interest or Additional

Amounts when due, no Holder of any of the Notes has any right to institute any proceedings with respect to this Indenture or any remedy thereunder, unless the Holders of at least 25% in aggregate principal amount of the outstanding Notes have made a written request to, and offered indemnity and/or security satisfactory to, the Trustee to institute such proceeding as trustee under the Notes and this Indenture, the Trustee has failed to institute such proceeding within 30 days after receipt of such notice and indemnity or security and the Trustee within such 30-day period has not received directions inconsistent with such written request by Holders of a majority in aggregate principal amount of the outstanding Notes. Such limitations do not, however, apply to a suit instituted by a Holder of a Note for the enforcement of the payment of the principal of, premium, if any, and Additional Amounts or interest on such Note on or after the respective due dates expressed in such Note.

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).


Section .	Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, interest and premium, Additional Amounts, if any, on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring proceedings for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of Holders of not less than 90% of the then outstanding aggregate principal amount of the Notes.


Section .	Collection Suit by Trustee.

If an Event of Default specified in Section 6.01 occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount of principal of, interest and premium then owing, Additional Amounts, if any, on the Notes and interest on overdue principal and, to the extent lawful, Additional Amounts, interest 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 .	Trustee May 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 (including any claim for the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuer, a Guarantor or any other obligor upon the Notes, their creditors or property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.


Section .	Priorities.

All moneys received by the Trustee under this Indenture shall be held by the Trustee in trust to apply them (subject to any legal privilege (if any) pursuant to any applicable Bankruptcy Law or any other applicable law):

First: to the Trustee (acting in any capacity hereunder), its agents and attorneys for amounts due under this Indenture, including payment of all compensation, expense and liabilities incurred, and all advances, if any, made, by the Trustee and the costs and expenses of collection;

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

Third: to the Issuer or to such party 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.


Section .	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 and expenses, 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 of a Note pursuant to Section 6.07, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.


Section .	Agents.

The Trustee shall be entitled to require all Agents to act under its direction following the occurrence and continuance of a Default or Event of Default.

ARTICLE 14TRUSTEE


Section .	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.

(b)Except during the continuance of an Event of Default:

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

(ii)in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture.

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

(e)No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the

request of any Holders, unless such Holder shall have offered to the Trustee security and/or indemnity satisfactory to it against any loss, liability or expense.

(f)The Trustee shall not be liable for interest on any money received by it or to make any investments except as the Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

Section .	Rights of Trustee.

(a)The Trustee may conclusively rely upon and will be protected in acting or refraining from acting upon, whether in its original, facsimile or other electronic form, any document reasonably believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document (regardless of whether any such document is subject to any monetary or other limit).

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

Delivery of reports, information and documents to the Trustee under Section 4.03 is for informational purposes only and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of their covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

(h)The Trustee shall not have any obligation or duty to monitor, determine or inquire as to compliance, and shall not be responsible or liable for compliance with restrictions on transfer, exchange, redemption, purchase or repurchase, as applicable, of minimum denominations imposed under this Indenture or under applicable law or regulation with respect to any transfer, exchange, redemption, purchase or repurchase, as applicable, of any interest in any Notes.

(p)The Trustee shall not under any circumstances be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer personally or by agent or attorney and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(q)The Trustee may request that the Issuer deliver an Officer’s Certificate setting forth the names of the individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be signed by any person authorized to sign an Officer’s Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

(r)No provision of this Indenture shall require the Trustee to do anything which, in its opinion, may be illegal or contrary to applicable law or regulation.

(t)The Trustee may retain professional advisors of its own selection to assist it in performing its duties under this Indenture. The Trustee may consult with such professional advisors or with counsel, and the advice or opinion of such professional advisors or counsel with respect to legal or other matters relating to this Indenture and the Notes shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

(u)The Trustee may assume without inquiry in the absence of actual knowledge that the Issuer is duly complying with its obligations contained in this Indenture required to be performed and observed by it, and that no Default or Event of Default or other event which would require repayment of the Notes has occurred.


Section .	Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such 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 .	Trustee’s Disclaimer.

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Issuer’s use of the proceeds from the Notes, 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. The Trustee shall be entitled to assume without inquiry that the Issuer has performed in accordance with all the provisions in this Indenture, unless notified to the contrary.


Section .	Notice of Defaults.

Subject to Section 7.02(g), if a Default or an Event of Default occurs and is continuing and is actually known to a Responsible Officer of the Trustee, the Trustee will mail to each Holder of the Notes notice of the Default or Event of Default within 15 Business Days after such Responsible Officer of the Trustee has actual notice of such occurrence. Except in the case of a Default or an Event of Default in payment of principal of, premium, if any, Additional Amounts or interest on any Notes, the Trustee may withhold the notice to the Holders of such Notes if it in good faith determines that withholding the notice is in the interests of the Holders of the Notes. The Issuer is required to furnish to the Trustee annual statements regarding compliance with the Indenture. Upon becoming aware of any Default or Event of Default, the Issuer is required to promptly deliver to the Trustee a statement specifying such Default or Event of Default and proposed steps to cure such Default or Event of Default.


Section .	Compensation and Indemnity.

(a)The Issuer shall pay to the Trustee (acting in any capacity hereunder) and Deutsche Bank AG, London Branch (acting in any capacity hereunder) from time to time compensation for its acceptance of this Indenture and services hereunder in accordance with the Trustee’s signed fee letter. 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 compensation, disbursements and expenses of the Trustee’s agents and counsel.

(b)The Issuer shall indemnify the Trustee (acting in any capacity hereunder) and Deutsche Bank AG, London Branch (acting in any capacity) (which for purposes of this Section 7.06 shall include their respective officers, directors, employees and agents) against any and all losses, liabilities or expenses incurred by it arising out of, or in connection with, the acceptance or administration of its duties under this Indenture, any supplemental indenture or accession agreement or the Notes or in any other role performed by Deutsche Bank Trust Company Americas under said documents, including the reasonable costs and expenses of enforcing this Indenture against the Issuer (including this Section 7.06) and defending itself against any claim (whether asserted by the Issuer or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its willful misconduct, gross negligence or bad faith. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may seek separate counsel and the Issuer shall pay the reasonably incurred fees and expenses of such counsel if the Issuer shall have failed to assume the defense thereof or employed counsel reasonably satisfactory to the Trustee. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

(c)The obligations of the Issuer under this Section 7.06 shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee (acting in any capacity hereunder) or Deutsche Bank AG, London Branch (acting in any capacity hereunder).

Such Lien shall survive the satisfaction and discharge of this Indenture.

(e)When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01 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.

(f)The indemnity contained in this Section 7.06 shall survive the discharge or termination of this Indenture and shall continue for the benefit of the Trustee or any Agent notwithstanding its resignation or retirement.

For the avoidance of doubt, the rights, privileges, protections, immunities and benefits given to the Trustee in this Section 7.06, including its right to be indemnified, are extended to, and shall be enforceable by, Deutsche Bank Trust Company Americas, as the Trustee, and by each agent (including Deutsche Bank Trust Company Americas as Principal Paying Agent, Transfer Agent and Registrar, Deutsche Bank AG, London Branch as Paying Agent) and Deutsche Bank Trust Company Americas as Custodian.

Upon such notice, a successor Agent shall be appointed by the Issuer, who shall provide written notice of such to the Trustee. Such successor Agent shall become the Agent hereunder upon the resignation or removal date specified in such notice. If the Issuer is unable to replace the resigning Agent within thirty (30) days after such notice, the Agent may, in its sole discretion, deliver any funds then held hereunder in its possession to the Trustee or may apply to a court of competent jurisdiction for the appointment of a successor Agent or for other appropriate relief.

ARTICLE 15

ARTICLE 16LEGAL DEFEASANCE AND COVENANT DEFEASANCE


Section .	Option to Effect Legal Defeasance or Covenant Defeasance.

The Issuer may at any time, at the option of its Board of Directors as evidenced by a resolution set forth in an Officer’s Certificate, elect to have either Section 8.02 or Section 8.03 applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.


Section .	Legal Defeasance and Discharge.

Upon the Issuer’s exercise under Section 8.01 of the option applicable to this Section 8.02, the Issuer, subject to the satisfaction of the conditions set forth in Section 8.04, will be deemed to have been discharged from its obligations with respect to the Notes issued under this Indenture and to have cured all then existing Events of Default on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all its other obligations under this Indenture, the Notes and any supplemental indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

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

(ii)the Issuer’s obligations with respect to such Notes under Article 2 and Section 4.02;

(iii)the rights, powers, trusts, duties and immunities of the Trustee and the obligations of the Issuer in connection therewith; and

(iv)this Article 8.

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


Section .	Covenant Defeasance.

Upon the Issuer’s exercise under Section 8.01 of the option applicable to this Section 8.03, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.04, be released from its respective obligations under the covenants contained in Article 4 (other than Sections 4.01 and 4.04) and Section 5.01 (other than Section 5.01(a)(iii)) with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that the Issuer may, with respect to the outstanding Notes, omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such Notes and any supplemental indenture shall be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.01 of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04, the Events of Default set forth in Section 6.01 (except those relating to clauses (a) or (b) or, solely with respect to the Issuer, (h) or (i) of Section 6.01) shall not constitute Events of Default.


Section .	Conditions to Legal or Covenant Defeasance.

(i)the Issuer must irrevocably deposit or cause to be deposited in trust with the Trustee, for the benefit of the Holders of the Notes, cash in dollars, non-callable U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient, in the opinion of an internationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay and discharge the principal of, premium, if any, and interest, on the outstanding Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and the Issuer must (A) specify whether the Notes are being defeased to such Stated Maturity or to a particular redemption date; and (B) if applicable, have delivered to the Trustee an irrevocable notice to redeem all the outstanding Notes of such principal, premium, if any, or interest;

(ii)in the case of an election under Section 8.02, the Issuer must have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee stating that (A) the Issuer has received from, or there has been published by, the U.S. Internal Revenue Service a ruling or (B) since the date of the Indenture, there has been a change in applicable U.S. federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the beneficial owners of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal 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 Legal Defeasance had not occurred;

(iii)in the case of an election under Section 8.03, the Issuer must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee to the effect that the beneficial owners 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;

(iv)the Issuer must have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by the Issuer with the intent of preferring the Holders of the Notes over the other creditors of the Issuer with the intent of defeating, hindering, delaying or defrauding creditors of the Issuer or others; and

(v)the Issuer must have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, reasonably acceptable to the Trustee, subject to customary assumptions and qualifications, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with.


Section .	Deposited Money and U.S. Government Obligations Held in Trust; Other Miscellaneous Provisions.

(a)Subject to Section 8.06, all money and non-callable U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as Paying Agent) as the Trustee may determine, to the Holders of the Notes of all sums due and to become due thereon in respect of principal, premium, interest and Additional Amounts, if any, but such money need not be segregated from other funds except to the extent required by law.

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

(c)Notwithstanding anything in this Article 8 to the contrary, the Trustee shall deliver or pay to the Issuer from time to time upon the request of the Issuer any money or non-callable U.S. Government Obligations held by it as provided in Section 8.04 which, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(i)), are in excess of the amount thereof that would then be required to be deposited to effect a Legal Defeasance or Covenant Defeasance, as applicable, of the type and scope originally effected by the Issuer pursuant to this Article 8.


Section .	Repayment to the Issuer.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium, interest or Additional Amounts on any Note and remaining unclaimed for two years after such principal or interest (and Additional Amounts or premium, if any) has become due and payable shall be paid to the Issuer on its request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may, at the expense of the Issuer, give notice to the Holders in accordance with Section 12.01 that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Issuer.


Section .	Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable U.S. Government Obligations in accordance with Section 8.02 or 8.03, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer’s obligations under this Indenture and the Notes and/or any supplemental indenture shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03, as the case may be; provided, however, that, if the Issuer makes any payment of principal of, premium, interest or Additional Amounts on any Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.


ARTICLE 17

ARTICLE 18AMENDMENT, SUPPLEMENT AND WAIVER


Section .	Without Consent of Holders of Notes.

Notwithstanding Section 9.02 of this Indenture, the Issuer and the Trustee may modify, amend or supplement this Indenture, the Notes or any supplemental indenture without the consent of any Holder of Notes:

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

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

(c)to provide for the assumption of the Issuer’s obligations to Holders of Notes by a successor to the Issuer in the case of a merger or consolidation or sale of all or substantially all of the Issuer’s assets;

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

(e)to conform the text of this Indenture or the Notes to any provision of the “Description of Notes” section of the Offering Memorandum to the extent that such provision in such Description of Notes was intended to be a verbatim recitation of a provision of this Indenture or the Notes, as evidenced by an Officer's Certificate;

(f)to allow any Guarantor to execute a supplemental indenture and/or Guarantee with respect to the Notes;

(g)to provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the U.S. Code);

(h)to evidence and provide the acceptance of the appointment of a successor Trustee under the terms of this Indenture or to otherwise comply with any requirement of this Indenture; or

(i)to provide for the issuance of Additional Notes in accordance with and if permitted by the terms of and limitations set forth in this Indenture.

In formulating its opinion on such matters, the Trustee shall be entitled to request and rely absolutely on such evidence as it deems appropriate, including an opinion of counsel and an Officer’s Certificate on which the Trustee may solely rely.

Upon the request of the Issuer and upon receipt by the Trustee of the documents described in Section 7.02(b), the Trustee will join with the Issuer in the execution of any amended or supplemental indenture or other document 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 will not be obligated to enter into such amended or supplemental indenture or other document that affects its own rights, duties or immunities under this Indenture.

In addition, the Issuer, the Trustee and a Restricted Subsidiary being added as a Guarantor may supplement this Indenture to add a guarantor under this Indenture without notice to or consent of any Holder.


Section .	With Consent of Holders of Notes.

Except as provided otherwise in Section 9.01 and this Section 9.02, the Issuer and the Trustee may amend or supplement this Indenture (including, without limitation, Section 4.14), the Notes and any supplemental indenture with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes) and, subject to Section 6.04 and Section 6.07 hereof, any existing Default or Event of Default (other than a continuing Default or Event of Default in the payment of the principal of, interest and premium and Additional Amounts, if any, on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Notes and any supplemental indenture may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes).

Upon the request of the Issuer, and upon receipt by the Trustee of the documents described in Section 7.02(b), the Trustee will join with the Issuer in the execution of such amended or supplemental indenture or other document unless such amended or supplemental indenture or other document directly affects the Trustee’s own rights, duties, immunities, privileges or indemnities under this Indenture, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture or other document.

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

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer will mail or otherwise deliver in accordance with Section 12.01 to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail or otherwise deliver such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or

waiver. Subject to Sections 6.04 and 6.07, the Holders of a majority in aggregate principal amount of the Notes then outstanding, voting as a single class, may waive compliance in a particular instance by the Issuer with any provision of this Indenture, the Notes or any supplemental indenture. However, unless consented to by the Holders of at least 90% of the aggregate principal amount of then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), without the consent of each Holder of Notes affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

(a)change the Stated Maturity of the principal of, or any installment of or Additional Amounts or interest on, any Note;

(b)reduce the principal amount of any Note (or Additional Amounts or premium, if any) or the rate of or change the time for payment of interest on any Note;

(c)change the coin or currency in which the principal of any Note or any premium or any Additional Amounts or the interest thereon is payable;

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

(e)reduce the principal amount of Notes whose Holders must consent to any amendment, supplement or waiver of provisions of this Indenture (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the Payment Default that resulted from such acceleration);

(f)modify any of the provisions relating to supplemental indentures requiring the consent of Holders of the Notes or relating to the waiver of past defaults or relating to the waiver of certain covenants, except to increase the percentage of outstanding Notes required for such actions or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Note affected thereby; or

(g)make any change in the preceding amendment and waiver provisions.

Any amendment, supplement or waiver consented to by at least 90% of the aggregate principal amount of the then outstanding Notes will be binding against any non-consenting Holders.


Section .	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 a 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 of the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.


Section .	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 Issuer, in exchange for Notes, may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate, or cause the Authentication Agent to authenticate, the new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.


Section .	Trustee to Sign Amendments.

The Trustee will sign any amended or supplemental indenture or other document authorized pursuant to this Article 9 if the amendment or supplement or other document does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In formulating its opinion on any of the matters in Section 9.01 and 9.02 and in executing any amended or supplemental indenture or other document, the Trustee will be entitled to receive and (subject to Section 7.01) will be fully protected in relying upon, in addition to the documents required by Section 12.02, (i) indemnity deemed satisfaction to it in its sole discretion; and (ii) an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture or other document is authorized or permitted by this Indenture and that such amendment is the legal, valid and binding obligation of the Issuer (and any Guarantor),

enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions of this Indenture.


ARTICLE 19

ARTICLE 20NOTE GUARANTEES


Section .	Guarantee.

(a)Subject to this Article 10, each of the Guarantors, if any, hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee or the Authentication Agent and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that:

(i)the principal of, Additional Amounts and premium, if any, and interest on, the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest, Additional Amounts and premium, if any, on the Notes (to the extent permitted by law) and all other obligations of the Issuer to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(ii)in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b)Each Guarantor hereby agrees that its obligations hereunder are 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 of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

(c)If any Holder or the Trustee is required by any court or otherwise to return to or for the benefit of the Issuer, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or the Guarantors, any amount paid by either the Issuer or the Guarantors to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(d)Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand,

(i)the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and

(ii)in the event of any declaration of acceleration of such obligations as provided in Article 6, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.


Section .	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 Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance, for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar national, federal, local or state law or voidable preference or improper corporate benefit, or violate the corporate purpose of the relevant Guarantor or any applicable maintenance of share capital or similar laws or regulations affecting the rights of creditors generally under any applicable law or regulation to the extent applicable to any Note Guarantee.

To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount (as may be set forth in a supplemental indenture to the extent reasonably determined by the Issuer) that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting either a fraudulent transfer or conveyance or voidable preference, financial assistance or improper corporate benefit, or violating the corporate purpose of the relevant Guarantor or any applicable capital maintenance or, in each case, any similar laws or regulations affecting the rights of creditors generally under any applicable law or regulation.


Section .	Execution and Delivery of Note Guarantee.

(a)To evidence its Note Guarantee set forth in this Section 10.01, the Issuer shall cause any Restricted Subsidiary that becomes a Guarantor after the Issue Date to do so by executing a supplemental indenture substantially in the form of Exhibit E to this Indenture and a notation of Note Guarantee substantially in the form of Exhibit D to this Indenture.

(b)Each Guarantor hereby agrees that its Note Guarantee will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

(c)If an Officer whose signature is on the Note Guarantee no longer holds that office at the time the Trustee or Authentication Agent authenticates the Note on which a Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.

(d)The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantor.


Section .	Releases.

The Note Guarantee of a Guarantor shall be released in accordance with Section 4.13(d) hereof. Upon any occurrence giving rise to a release of a Note Guarantee, as specified above, the Trustee, subject to receipt of certain documents (including an Officer’s Certificate and an Opinion of Counsel reasonably acceptable to the Trustee) from the Issuer and/or Guarantor, will execute any documents reasonably required in order to evidence or effect such release, discharge and termination in respect of such Note Guarantee. Neither the Issuer, the Trustee nor any Guarantor will be required to make a notation on the Notes to reflect any such release, discharge or termination.

Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 10.04 will remain liable for the full amount of principal of, premium on, if any, interest and Additional Amounts, if any, on, the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.


ARTICLE 21

ARTICLE 22SATISFACTION AND DISCHARGE


Section .	Satisfaction and Discharge.

(a)This Indenture and the Notes will be discharged and will cease to be of further effect, when:

(i)either:

(A)all the Notes that have been authenticated and delivered (other than destroyed, lost or stolen Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust and thereafter repaid to the Issuer or discharged from such trust as provided for in this Indenture) have been delivered to the Trustee for cancellation; or

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

(ii)the Issuer has paid or caused to be paid all sums payable by the Issuer under this Indenture and the Notes; and

(iii)the Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be.

In addition, the Issuer must deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel, subject to customary assumptions and qualifications, each stating that all conditions precedent provided in this Indenture relating to the satisfaction and discharge of the Indenture have been satisfied; provided that any such counsel in providing such opinion may rely on any Officer’s Certificate as to matters of fact (including as to compliance with the foregoing clauses (i), (ii) and (iii) of this Section 11.01(a)).

(b)With respect to the termination of obligations with respect to Section 11.01(a)(i)(A), the obligations of the Issuer under Section 7.06 shall survive. With respect to the termination of obligations with respect to Section 11.01(a)(i)(B), the obligations of the Issuer in Sections 2.03 (solely to the extent necessary to carry out its obligations that remain under this Indenture), 2.06, 2.07, 2.12, 4.01, 4.02 (solely to the extent necessary to carry out its obligations that remain under this Indenture), 4.06, 7.06, 7.07, 8.05 and 8.07 shall survive until the Notes are no longer outstanding. Thereafter, only the obligations of the Issuer in Sections 7.06, 7.07 and 8.07 shall survive. After any such irrevocable deposit and receipt of the Officer’s Certificate and Opinion of Counsel, the Trustee upon request shall acknowledge in writing the discharge of the obligations of the Issuer under this Indenture, the Notes, and any supplemental indenture, except for those surviving obligations specified above.

(c)Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to Section 11.01(a)(i)(B), the provisions of Sections 8.06 and 11.02 will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.06, that, by their terms, survive the satisfaction and discharge of this Indenture.


Section .	Application of Trust Money.

(a)Subject to the provisions of Section 8.05, all money deposited with the Trustee pursuant to Section 11.01 shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal, Additional Amounts and premium, if any, and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

(b)If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Section 11.02 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01; provided that if the Issuer has made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

The Issuer has appointed ▇▇▇▇▇▇ & ▇▇▇▇▇▇, LLP (attn: ▇▇▇▇ ▇. ▇▇▇▇▇, Esq. and ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Esq.) as its authorized agent upon whom process may be served in any such suit, action or proceeding which may be instituted in any federal or state court located in the State of New York, Borough of Manhattan arising out of or based upon this Indenture, the Notes or the transactions contemplated hereby or thereby, and any action brought under U.S. federal or state securities laws (the

“Authorized Agent”). The Issuer expressly consents to the jurisdiction of any such court in respect of any such action and waives any other requirements of or objections to personal jurisdiction with respect thereto and waives any right to trial by jury. Such appointment shall be irrevocable unless and until replaced by an agent reasonably acceptable to the Trustee. The Issuer represents and warrants that the Authorized Agent has agreed to act as said agent for service of process, and the Issuer agrees to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect as aforesaid.

The waiver may not be effective to waive liabilities under the U.S. federal securities laws.


Section .	Governing Law.

THIS INDENTURE AND THE NOTES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.


Section .	No Adverse Interpretation of Other Agreements.

This Indenture may not be used to interpret any other indenture, loan or debt agreement of the Issuer or any of its respective Subsidiaries or of any other Person. Any such indenture, loan or debt agreement may not be used to interpret this Indenture.

Section .	Counterpart Originals.

The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes.


Section .	Table of Contents, Headings, etc.

The Table of Contents and headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and shall in no way modify or restrict any of the terms or provisions hereof.


Section .	Judgment Currency.

Any payment on account of an amount that is payable in U.S. Dollars, which is made to or for the account of any Holder or the Trustee in lawful currency of any other jurisdiction (the “Judgment Currency”), whether as a result of any judgment or order or the enforcement thereof or the liquidation of the Issuer, shall constitute a discharge of the Issuer’s obligation under this Indenture and the Notes only to the extent of the amount of U.S. dollars that such Holder or the Trustee, as the case may be, could purchase in the London foreign exchange markets with the amount of the Judgment Currency in accordance with normal banking procedures at the rate of exchange prevailing on the first

Business Day following receipt of the payment in the Judgment Currency. If the amount of U.S. dollars that could be so purchased is less than the amount of U.S. dollars originally due to such Holder or the Trustee, as the case may be, the Issuer shall indemnify and hold harmless the Holder or the Trustee, as the case may be, from and against all loss or damage arising out of, or as a result of, such deficiency. This indemnity shall constitute an obligation separate and independent from the other obligations contained in this Indenture or the Notes, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by any Holder or the Trustee from time to time and shall continue in full force and effect notwithstanding any judgment or order for a liquidated sum in respect of an amount due hereunder or under any judgment or order.


Section .	Prescription.

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) INTEREST. North Atlantic Drilling Ltd., an exempted company limited by shares incorporated under the laws of Bermuda, with its registered trade offices at ▇▇▇-▇▇-▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇ ▇▇▇-▇▇-▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇ ▇▇, ▇▇▇▇▇▇▇ and registered with the Bermuda Registrar of Companies under number 45094 (the “Issuer”), promises to pay interest on the principal amount of this Note at 6.25% per annum from January 31, 2014 until maturity and shall pay Additional Amounts, if any, payable pursuant to Section 4.17 of the Indenture. The Issuer will pay interest and Additional Amounts (if any) semi-annually in arrears on February 1 and August 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). 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 issuance; provided that if there is no existing 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; provided, further, that the first Interest Payment Date shall be August 1, 2014. The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to 1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful. The Issuer shall pay interest (including post‑petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful. Interest will be computed on the basis of a 360‑day year of twelve 30‑day months.

(2) METHOD OF PAYMENT. The Issuer will pay interest on this Note (except defaulted interest) and Additional Amounts, if any, to the Persons who are registered Holders of Notes at the close of business on February 1 or August 1 preceding the next 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 2.11 of the Indenture with respect to defaulted interest. This Note will be payable as to principal, interest, premium and Additional Amounts, if any, through the Paying Agents as provided in the Indenture. Such payment shall be in U.S. dollars.

(3) PAYING AGENT AND REGISTRAR. Initially, Deutsche Bank Trust Company Americas will act as Principal Paying Agent, Transfer Agent and Registrar. Deutsche Bank AG, London Branch will act as Paying Agent in London, United Kingdom, for so long as the Notes are listed on the Irish Stock Exchange and admitted for trading on the Global Exchange Market and the rules and regulations of the Irish Stock Exchange so require. The Issuer may change any Paying Agent, Registrar or Transfer Agent (subject, in the case of a Paying Agent, to the condition described in the first paragraph in Section 2.03 of the Indenture) without prior notice to the Holders. For so long as the Notes are listed on the Irish Stock Exchange and admitted for trading on the Global Exchange Market and the rules and regulations of the Irish Stock Exchange so require, the Issuer will publish a notice of any change of Paying Agent, Registrar or Transfer Agent in a newspaper having a general circulation in Ireland (which is currently expected to be the Irish Times) or, to the extent and in the manner permitted by such rules, post such notice on the official website of the Irish Stock Exchange (▇▇▇.▇▇▇.▇▇), in accordance with Section 12.01 of the Indenture.

(4) INDENTURE. The Issuer issued this Note under an Indenture dated as of January 31, 2014 (the “Indenture”) between the Issuer, the Trustee and Deutsche Bank AG, London Branch, as Paying Agent. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Indenture does not limit the aggregate principal amount of the Notes that may be issued thereunder.

(5) OPTIONAL REDEMPTION.

(a) At any time prior to February 1, 2017, the Issuer may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes issued under the Indenture, upon not less than 30 nor more than 60 days’ notice to the Trustee and Holders of Notes, at a redemption price equal to 106.25% of the principal amount of the Notes redeemed, plus accrued and unpaid interest and Additional Amounts, if any, to the redemption date (subject to the rights of Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date), with the net cash proceeds of one or more Equity Offerings; provided that:

(i) at least 65% of the aggregate principal amount of Notes issued under the Indenture (excluding Notes held by the Issuer and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

(ii) such redemption occurs not more than 180 days after the date of the closing of the relevant Equity Offering.

(b) The Issuer may on any one or more occasions redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest and Additional Amounts, if any, to the date of redemption, subject to the rights of Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date.

(c) Except pursuant to subsections (a) and (b) of this Paragraph 5 and pursuant to Paragraph 6, the Notes will not be redeemable at the Issuer’s option.

(6) REDEMPTION UPON CHANGES IN WITHHOLDING TAXES.

The Issuer may redeem the Notes, in whole but not in part, at its discretion at any time upon giving not less than 30 nor more than 60 days’ prior notice to the Holders of the Notes (which notice will be irrevocable and given in accordance with the procedures described in Section 3.03 and Section 12.01 of the Indenture), at a redemption price equal to the principal amount thereof, together with accrued and unpaid interest, if any, to the date fixed by the Issuer for redemption (a “Tax Redemption Date”) and all Additional Amounts (if any) then due and which will become due on the Tax Redemption Date as a result of the redemption or otherwise (subject to the right of Holders of the Notes on the relevant record date to receive interest due on an interest payment date that is prior to the Tax Redemption Date and Additional Amounts (if any) in respect thereof), if on the next date on which any amount would be payable in respect of the Notes, the Issuer is or would be required to pay Additional Amounts, and the Issuer cannot avoid any

such payment obligation by taking reasonable measures available to it (including, for the avoidance of doubt, the designation of a Paying Agent in another jurisdiction), and the requirement arises as a result of:

(i) any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the relevant Tax Jurisdiction affecting taxation, which change or amendment has not been formally proposed before and which becomes effective on or after the Issue Date (or, if the relevant Tax Jurisdiction was not a Tax Jurisdiction on the Issue Date, the date on which such Tax Jurisdiction became a Tax Jurisdiction under the Indenture); or

(ii) any change in, or amendment to, an official written position regarding the application, administration or interpretation of such laws, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction or a change in published administrative practice), which change or amendment has not been formally proposed before and becomes effective on or after the Issue Date (or, if the relevant Tax Jurisdiction was not a Tax Jurisdiction on the Issue Date, the date on which such Tax Jurisdiction became a Tax Jurisdiction under the Indenture).

The Issuer will not give any such notice of redemption earlier than 60 days prior to the earliest date on which the Issuer would be obligated to make such payment or withholding if a payment in respect of the Notes were then due, and at the time such notice is given, the obligation to pay Additional Amounts must remain in effect. Prior to the publication or, where relevant, mailing of any notice of redemption of the Notes pursuant to the foregoing, the Issuer will deliver to the Trustee a written opinion of independent tax counsel of recognized standing qualified under the laws of the relevant Tax Jurisdiction, such counsel to be subject to the prior written approval of the Trustee, to the effect that there has been such change or amendment which would entitle the Issuer to redeem the Notes hereunder. In addition, before the Issuer publishes or mails notice of redemption of the Notes as described above, it will deliver to the Trustee an Officers’ Certificate to the effect that the obligation to pay Additional Amounts cannot be avoided by the Issuer taking reasonable measures available to it.

The Trustee will accept such Officers’ Certificate and Opinion of Counsel as sufficient evidence of the existence and satisfaction of the conditions precedent as described above, in which event it will be conclusive and binding on the Holders.

(7) MANDATORY REDEMPTION. The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

(8) REPURCHASE AT OPTION OF HOLDER. If a Change of Control occurs, each Holder of Notes will have the right to require the Issuer to repurchase all or any part (equal to $200,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to an offer by the Issuer (a “Change of Control Offer”) on the terms set forth in the Indenture. In the Change of Control Offer, the Issuer will offer a payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest and Additional Amounts, if any, on the Notes repurchased to the date of purchase (the “Change of Control Payment”), subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date. Unless the Issuer has unconditionally exercised its right to redeem all the Notes as described under Section 3.07 of the Indenture or all conditions to such redemption have been satisfied or waived, within 30 days following any Change of Control, the Issuer will mail a notice to each Holder of the Notes at such Holder’s registered address or otherwise deliver a notice in accordance with the procedures required by Section 4.14 of the Indenture.

(9) NOTICE OF REDEMPTION. At least 30 days but not more than 60 days before a redemption date, the Issuer shall deliver, pursuant to Section 12.01 of the Indenture, a notice of redemption to each Holder whose Notes are to be redeemed, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is

issued in connection with a defeasance of the Notes or the satisfaction and discharge of the Indenture pursuant to Articles 8 or 11 of the Indenture. Notes in denominations larger than $200,000 may be redeemed in part but only in whole multiples of $1,000 in excess thereof, unless all of the Notes held by a Holder are to be redeemed.

(10) DENOMINATIONS, TRANSFER, EXCHANGE. [The Global Notes are in global registered form without coupons attached. The Global Notes will represent the aggregate principal amount of all the Notes issued and not yet cancelled other than Definitive Registered Notes. A Holder may transfer or exchange Global Notes in accordance with the Indenture.] Include in any Global Note. [The Definitive Registered Notes are in registered form without coupons attached in denominations of $200,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Definitive Registered Notes in accordance with the Indenture. The Indenture requires a Holder, among other things, to furnish appropriate endorsements and transfer documents. The Issuer shall not be required to register the transfer into its register kept at its registered office of any Definitive Registered Notes: (A) for a period of 15 calendar days prior to any date fixed for the redemption of the Notes under Section 3.03 of the Indenture; (B) for a period of 15 calendar days immediately prior to the date fixed for selection of Notes to be redeemed in part; (C) for a period of 15 calendar days prior to the record date with respect to any interest payment date; or (D) which the Holder has tendered (and not withdrawn) for repurchase in connection with a Change of Control Offer.] Include in any Definitive Registered Note.

(11) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

(12) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Issuer and the Trustee may amend or supplement the Indenture, the Notes and any supplemental Indenture with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes) and, subject to Section 6.04 and Section 6.07 of the Indenture, any existing Default or Event of Default (other than a continuing Default or Event of Default in the payment of the principal of, interest and premium and Additional Amounts, if any, on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of the Indenture, the Notes and any supplemental indenture may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes). Without the consent of any Holder, the Issuer and the Trustee may modify, amend or supplement the Indenture, the Notes or any supplemental indenture to cure any ambiguity, defect or inconsistency; to provide for uncertificated Notes in addition to or in place of certificated Notes; to provide for the assumption of the Issuer’s obligations to Holders of Notes by a successor to the Issuer in the case of a merger or consolidation or sale of all or substantially all of the Issuer’s assets; to make any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely affect the legal rights under the Indenture of any such Holder in any material respect; to conform the text of the Indenture or the Notes to any provision of the “Description of Notes” section of the Offering Memorandum to the extent that such provision in such Description of Notes was intended to be a verbatim recitation of a provision of the Indenture or the Notes, as evidenced by an Officer’s Certificate; to allow any Guarantor to execute a supplemental indenture and/or Guarantee with respect to the Notes; to provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the U.S. Code); to evidence and provide the acceptance of the appointment of a successor Trustee under the terms of the Indenture or to otherwise comply with any requirement of the Indenture; or to provide for the issuance of Additional Notes in accordance with and if permitted by the terms of and limitations set forth in the Indenture.

clauses (a), (b) or (c) of Section 6.01 of the Indenture); (v) default under the terms of any instrument evidencing or securing the Indebtedness of the Issuer or any Restricted Subsidiary, if that default: (I) results in the acceleration of the payment of such Indebtedness or (II) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness at the Stated Maturity thereof prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”), and in either case the total amount of such Indebtedness unpaid or accelerated exceeds $50.0 million; (vi) failure by the Issuer or any of its Restricted Subsidiaries to pay final judgments, orders or decrees (not subject to appeal) entered by a court or courts of competent jurisdiction aggregating in excess $50.0 million (exclusive of any amounts that an insurance company has acknowledged liability for), which judgments shall not have been discharged or waived and there shall have been a period of 60 consecutive days or more during which a stay of enforcement of such judgment, order or decree (by reason of pending appeal, waiver or otherwise) shall not have been in effect; (vii) the Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of its Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary (I) commences a voluntary case, (II) consents to the entry of an order for relief against it in an involuntary case, (III) consents to the appointment of a custodian of it or for all or substantially all of its property, (IV) makes a general assignment for the benefit of its creditors, or (V) admits in writing its inability to pay its debts generally as they become due; and (viii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (I) is for relief against the Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of its Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary in an involuntary case, (II) appoints a custodian or administrator of the Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of its Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of the Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of its Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or (III) orders the liquidation of the Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of its Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, and in each case, the order or decree remains unstayed and in effect for 60 consecutive days. If an Event of Default specified in clause (vii) or (viii) occurs and is continuing, then the principal of, premium, if any, and Additional Amounts and accrued and unpaid interest on all the outstanding Notes shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of Notes. If an Event of Default (other than as specified in clauses (vii) or (viii) above) occurs and is continuing, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer (and to the Trustee if such notice is given by the Holders) may, and the Trustee, upon the written request of such Holders, shall, declare the principal of, premium, if any, and any Additional Amounts and accrued interest on all the outstanding Notes immediately due and payable, and upon any such declaration all such amounts payable in respect of the Notes will become immediately due and payable.

Subject to certain limitations, Holders of a majority in aggregate principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Holders of a majority in aggregate principal amount of the Notes then outstanding by written notice to the Trustee may rescind any acceleration and its consequence if the Parent Guarantor has paid or deposited with the Trustee a sum as set forth in Section 6.02(c)(i) of the Indenture; the rescission would not conflict with any judgment or decree; and if all existing Events of Default have been cured or waived except nonpayment of principal, premium, if any, any Additional Amounts or interest that has become due solely because of such acceleration. The above description of Events of Default and remedies is qualified by reference, and subject in its entirety, to the provisions of the Indenture.

(14) TRUSTEE DEALINGS WITH ISSUER. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee.

(15) NO RECOURSE AGAINST OTHERS. No director, officer, affiliate, employee, incorporator, member or shareholder of the Issuer will have any liability for any obligations of the Issuer under the Notes or the Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the U.S. federal securities laws.

(17) ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common) and U/G/M/A (= Uniform Gifts to Minors Act).

(18) CUSIP, ISIN AND COMMON CODE NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders.
