(b)          Neither any members of, nor participants in, DTC (the “ DTC Participants ”) nor any other Persons on whose behalf DTC Participants may act, shall have any rights under this Indenture with respect to any Global Note, and DTC or its nominee, as the case may be, may be treated by the Issuer, the Trustee and any agent thereof (including any Authorized Agent) as the absolute owner and Holder of such Global Note for all purposes whatsoever. Unless and until Definitive Notes are issued in exchange for such Global Notes pursuant to ‎ Section 2.8 : (i) the Issuer, the Trustee and any agent thereof (including any Authorized Agent) may deal with DTC and its nominee for all purposes (including the making of distributions on the Global Notes) as the authorized representatives of the Persons holding beneficial interests in such Global Notes and (ii) the rights of such beneficial owners shall be exercised only through DTC and its nominee and shall be limited to those established by Applicable Law and agreements among such DTC Participants, DTC and such nominee.

Upon receipt by the Trustee at its Corporate Trust Office of: (i) written instructions given in accordance with the Applicable Procedures from a DTC Participant directing the Trustee to credit or cause to be credited to a specified DTC Participant’s account a beneficial interest in the Regulation S Note in a principal balance equal to that of the beneficial interest in the Rule 144A Note to be so exchanged or transferred, (ii) a written order given in accordance with the Applicable Procedures containing information regarding the account of the DTC Participant to be credited with, and the account of the DTC Participant to be debited for, such beneficial interest and (iii) a certificate in substantially the form of Exhibit B given by the holder of such beneficial interest in the Rule 144A Note, the Trustee shall instruct DTC to reduce the balance of the Rule 144A Note, and to increase the balance of the Regulation S Note, by the amount of the beneficial interest in the Rule 144A Note to be so exchanged or transferred, and to credit or cause to be credited to the account of the DTC Participant for the benefit of such Person specified in such instructions a beneficial interest in the Regulation S Note having a principal balance equal to the amount by which the balance of the Rule 144A Note was reduced upon such exchange or transfer.

 (c)         If the owner of a beneficial interest in the Regulation S Note wishes at any time to exchange its beneficial interest therein for a beneficial interest in the Rule 144A Note, or to transfer such beneficial interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Rule 144A Note, then such exchange or transfer may be effected, subject to the Applicable Procedures and minimum denomination requirement, only in accordance with this ‎ Section 2.6(c) . Upon receipt by the Trustee at its Corporate Trust Office of: (i) written instructions given in accordance with the Applicable Procedures from a DTC Participant directing the Trustee to credit or cause to be credited to a specified DTC Participant’s account a beneficial interest in the Rule 144A Note in a principal balance equal to that of the beneficial interest in the Regulation S Note to be so exchanged or transferred, (ii) a written order given in accordance with the Applicable Procedures containing information regarding the account of the DTC Participant to be debited with, and the account of the DTC Participant to be credited for, such beneficial interest and (iii) a certificate in substantially the form set forth in Exhibit C given by the holder of such beneficial interest in the Regulation S Note, the Trustee shall instruct DTC to reduce the balance of the Regulation S Note and to increase the balance of the Rule 144A Note, by the principal balance of the beneficial interest in the Regulation S Note to be so exchanged or transferred, and to credit or cause to be credited to the account of the DTC Participant for the benefit of such Person specified in such instructions a beneficial interest in the Rule 144A Note having a principal balance equal to the amount by which the balance of the Regulation S Note was reduced upon such exchange or transfer.

(b)           The required legends set forth on Exhibit A may be removed from a Global Note if there is delivered to the Issuer and the Trustee such evidence satisfactory to the Issuer, which shall include an Opinion of Counsel, as may reasonably be required by the Issuer that neither such legend nor the restrictions on transfer set forth therein are required to ensure that transfers of such Note (or beneficial interests therein) will not violate the registration requirements of the Securities Act or Canadian securities laws, as the case may be. Upon provision of such evidence satisfactory to the Issuer, the Trustee, at the written direction of the Issuer, shall authenticate and deliver in exchange for such Note a Note (or Notes) having an equal aggregate principal balance that does not bear such legend. If such a legend required for a Note has been removed as provided above, then no other Note issued in exchange for all or any part of such Note shall bear such legend unless the Issuer has reasonable cause to believe that such other Note is a “ restricted security ” within the meaning of Rule 144 under the Securities Act and instructs the Trustee to cause a legend to appear thereon.

(c)           The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or Applicable Law with respect to any transfer of any interest in any Note (including any transfers between or among DTC Participants or owners of beneficial interests in any Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, this Indenture, and to examine the same to determine material compliance as to form with the express requirements hereof.

If (a) DTC notifies the Trustee in writing that it is unwilling or unable to continue as the depository for a Global Note, or that it ceases to be a “ clearing agency ” registered under the Exchange Act and (b) the Issuer is unable to locate a qualified successor depository within 90 days of such notice, then the Trustee shall notify all applicable Holders, through DTC, of the occurrence of any such event and of the availability of Definitive Notes to beneficial owners. Upon the giving of such notice and the surrender of the Global Notes by DTC, accompanied by registration instructions, the Trustee shall deliver Definitive Notes (which shall be in definitive, fully registered, non-global form without interest coupons) for the Global Notes. If Definitive Notes are to be issued in accordance with this ‎ Section 2.8 , then the Issuer shall promptly make available to the Trustee a reasonable supply of Definitive Notes. Unless counsel to the Issuer determines otherwise in accordance with Applicable Law and the procedures set forth in ‎ Section 2.7(b) , any such Definitive Notes shall bear the appropriate transfer-restriction legends. In addition, in the event that the Global Note(s) is exchanged for definitive Notes, an announcement of such exchange will be made by or on behalf of the Issuer through the SGX-ST. Such announcement will include all material information with respect to the delivery of the definitive Notes including details of the paying agent and listing agent in Singapore.

Until Definitive Notes are ready for delivery, the Issuer may prepare and, upon receipt of written instructions by the Issuer, the Trustee shall 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. Without unreasonable delay, the Issuer shall prepare and, upon receipt of written instructions by the Issuer, the Trustee shall authenticate Definitive Notes and deliver them in exchange for temporary Notes.

All interest shall be computed on the basis of a 360-day year of twelve 30-day months and will be payable to the Holders of record on the close of business on the Record Date immediately preceding the corresponding Payment Date. Payments due on a date other than a Business Day shall be made on the next succeeding Business Day and such extension of time shall not be included in computing interest and fees in connection with that payment.

(d)          The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law to the extent that such interest is an allowed claim enforceable against the debtor under any Bankruptcy Law) on overdue principal and premium, if any, at a rate equal to 1.00% per annum in excess of the interest rate on the Notes, and to the extent lawful, it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law to the extent that such interest is an allowed claim against the debtor under such Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) from time to time on demand at the same rate. The Issuer will pay to the Holders such defaulted interest in any lawful manner on a special record date. The Issuer will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Trustee will fix or cause to be fixed each such special record date and payment date, provided , however , that no such special record date will be less than 10 days prior to the related payment date for such defaulted interest. At least 10 days before the special record date, the Issuer will mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such defaulted interest to be paid.

(e)          Except as specified in ‎ Section 2.10(f) , payments of all amounts that become due and payable in respect of any Note shall be made by the Paying Agent without surrender or presentation of such Note to the Paying Agent.

Unless such designation for payment by electronic funds transfer is revoked in writing, any such designation made by such Holder shall remain in effect with respect to any future payments to such Holder.

Section 2.11         Additional Notes . Subject to the limitations set forth under ‎ Section 4.1(f) , the Issuer may, without the consent of any Holder, incur additional Indebtedness. At the Issuer’s option, this additional Indebtedness may consist of additional Notes (“ Additional Notes ”) issued pursuant to this Indenture in one or more transactions, which have identical terms (other than issue price, issue date and date from which interest thereon will accrue) as the Notes issued on the Closing Date. Any Additional Notes will be consolidated and form a single class with the Notes issued on the Closing Date, so that, among other things, Holders of any Additional Notes will have the right to vote together with Holders of Notes issued on the Closing Date as one class; provided , however , that if such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, the additional notes will have a separate CUSIP number. In authenticating such Additional Notes, the Trustee shall receive, and shall be fully protected in relying upon, an Opinion of Counsel which shall state:

(a)         that the form and terms of such Additional Notes have been established in conformity with the provisions of this Indenture; and

In the event that any Taxes are required by Applicable Law to be deducted or withheld from any payment required to be made in respect of the Notes, then the amount of such payment shall be increased by an amount (“ Additional Amount s”) as may be necessary such that the amount actually received by the applicable recipients or beneficial owner of such payment in respect of such payment, after withholding or deduction for or on account of such Taxes, is an amount equal to the amount that would have been received by the applicable recipient(s) or beneficial owner of such payment in respect of such payment had no such Taxes (including any Taxes payable in respect of such Additional Amounts) been required to be so deducted or withheld. Furthermore, the amount of any Taxes required to be withheld or deducted from any payment made in respect of the Notes shall be withheld or deducted from such payment (as increased by any Additional Amounts) and paid to the taxing authority imposing such Taxes in accordance with Applicable Law. Together with every payment made under this Indenture requiring the withholding of any Taxes, the Issuer shall furnish to the Trustee a statement of the withholding being made, if any, in the form of a debit notice on account of tax withholding or other similar document which evidences that the withholding was duly made. As promptly as practicable thereafter, the Issuer shall provide the Trustee documentation satisfactory to the Trustee evidencing payment of Taxes in respect of which the Issuer has paid any Additional Amounts. Copies of such documentation shall be made available to the Holders or any Paying Agent upon request therefor to the trustee.

Notwithstanding the preceding sentences, no such Additional Amounts will (including Taxes payable in respect of such Additional Amounts) be payable in respect of:

(1)       any Tax assessed or imposed by reason of the applicable recipient or beneficial owner of such payment having any actual or deemed present or former connection between the recipient or beneficial owner of such payment and a Relevant Taxing Jurisdiction (including, without limitation, being a citizen of, carrying on business or having a permanent establishment in a Relevant Taxing Jurisdiction, being organized under the laws of a Relevant Taxing Jurisdiction, being an actual or deemed resident of a Relevant Taxing Jurisdiction or, in the case of Canada, dealing at non-arm’s length (for the purposes of the Income Tax Act (Canada)) with the payer of such payment;

(2)       any Taxes imposed on or measured by the applicable recipient or beneficial owner’s net income, capital franchise taxes and branch profits or similar taxes;

(3)       any estate, inheritance, gift, personal property, sales, use, excise, transfer or other similar Tax imposed with respect to such payment;

(4)       any such Taxes that would not have been imposed but for the failure of the applicable recipient or beneficial owner of such payment to comply with any certification, identification, information, documentation or other reporting requirement to the extent (a) such compliance is required by applicable law or an applicable treaty as a precondition to exemption from, or reduction in the rate of deduction or withholding of, such Taxes and (b) reasonably in advance of the first Payment Date with respect to which the obligor with respect to a payment shall apply this clause (4), such obligor shall have notified each Holder in writing that taxes will be imposed unless an applicable compliance certification, identification, information, documentation or other reporting requirement is satisfied;

(5)       any such Taxes required to be withheld by any paying agent from any payment, if such payment can be made in a commercially reasonable manner without such withholding by any other paying agent with respect to the Notes;

(6)       any Note presented for payment (where presentation is required) more than 30 days after the relevant payment is first made available for payment to the applicable recipient (except to the extent that such recipient would have been entitled to Additional Amounts had the Note been presented during such 30-day period);

(7)       any Tax payable other than by withholding or deduction;

(8)       any United States federal withholding tax;

(9)       any tax, assessment, withholding or deduction required by FATCA, any current or future Treasury regulations or rulings promulgated thereunder, any law, regulation or other official guidance enacted in any jurisdiction implementing FATCA, any intergovernmental agreement between the United States and any other jurisdiction pursuant to the implementation of FATCA, or any agreement with the United States Internal Revenue Service pursuant to the implementation of FATCA; or

(10)       any combination of the circumstances described in clauses (1) through (9),

nor will any Additional Amounts be paid with respect to any payment to a recipient who is a fiduciary, partnership, limited liability company or any person other than the sole beneficial owner of such payment to the extent that a beneficiary or settlor with respect to such fiduciary or a member of such partnership or limited liability company or a beneficial owner would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been in the place of such recipient.

In addition, the Issuer shall pay any and all Other Taxes imposed by a Relevant Taxing Jurisdiction imposing such Other Taxes in accordance with Applicable Law.

The obligation of the Issuer to pay Additional Amounts will survive the repayment of the Notes and the sale or transfer of the Notes (or beneficial interests therein) by any investor.

For purposes of the provisions described in this ‎ Section 2.12 , the term “ applicable recipient ” means the direct nominee of any beneficial owner of the relevant Note, which holds such beneficial owner’s interest in such Note.

In the event there after the Closing Date there has been any change with respect to any Taxes required by Applicable Law to be deducted or withheld from any payment required to be made in respect of the Notes causing a change in the Additional Amounts payable, at least thirty (30) days prior to the first date of payment of interest on the Notes and at least thirty (30) days prior to each date, if any, of payment of principal or interest thereafter (but only if there has been any change with respect to the matters set forth in any previously delivered Officers’ Certificate) the Issuer shall furnish the Trustee and each Paying Agent with an Officers’ Certificate instructing the Trustee and such Paying Agent as to whether such payment of principal of or any interest on such Notes shall be made without deduction or withholding for or on account of any tax, duty, assessment or other governmental charge. If any such deduction or withholding shall be required then such certificate shall specify the amount, if any, required to be deducted or withheld on such payment to the relevant recipient, and the Issuer shall pay or cause to be paid to the Trustee or such Paying Agent Additional Amounts, if any, required by this ‎ Section 2.12 . The Issuer agrees to indemnify the Trustee and each Paying Agent for, and to hold them harmless against, any loss, liability or expense (including attorneys’ fees) reasonably incurred without gross negligence or willful misconduct on their part arising out of or in connection with actions taken or omitted by it in reliance on any Officers’ Certificate furnished pursuant to this ‎ Section 2.12 and neither the Trustee nor the Paying Agent shall be responsible or liable for determining any withholding amount, for the accuracy of any determination or calculation or for determining if any withholding is required under Applicable Law.

Whenever in this Indenture there is mentioned, in any context, the payment of principal, premium, if any, interest or any other amount payable under or with respect to any Note, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this ‎ Section 2.12 , to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this ‎ Section 2.12 and express mention of the payment of Additional Amounts in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made.

Section 2.13         Mutilated, Destroyed, Lost or Stolen Notes . In case any Note shall become mutilated, defaced, destroyed, lost or stolen, the Issuer will execute and the Trustee will, upon written direction by the Issuer, authenticate, register and deliver a new Note of like tenor (including the same date of issuance) and equal principal amount registered in the same manner, dated the date of its authentication and bearing interest from the date to which interest has been paid on such Note (or if no interest has been paid, from the issue date), in exchange and substitution for such Note (upon surrender and cancellation thereof in the case of mutilated or defaced notes) or in lieu of and in substitution for such Note. In case a Note is destroyed, lost or stolen, the applicant for a substitute Note shall furnish the Issuer and the Trustee (a) such security or indemnity as may be required by them to save each of them harmless and (b) satisfactory evidence of the destruction, loss or theft of such Note and of the ownership thereof. Upon the issuance of any substituted Note, the Trustee may require the payment by the registered Holder thereof of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any fees and expenses (including those of the Trustee) connected therewith. With respect to mutilated, defaced, destroyed, lost or stolen Definitive Notes, a Holder thereof may obtain new definitive registered Notes from the office of the Transfer Agent.

Notwithstanding any statement herein, the Issuer and the Trustee reserve the right to impose such transfer, certificate, exchange or other requirements, and to require such restrictive legends on Notes, as they may determine are necessary to ensure compliance with the securities laws of the United States and the states therein and any other applicable laws.

Section 2.14         Cancellation . (a) All Notes surrendered for payment, exchange or redemption, or deemed lost or stolen, shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee by such Person and shall be promptly canceled by the Trustee (or, if lost or stolen and not yet replaced pursuant to ‎ Section 2.13 , delivered to the applicable Holder). No Note shall be authenticated in lieu of or in exchange for any Note canceled as provided in this Section except as expressly permitted by this Indenture. All canceled Notes held by the Trustee shall be disposed of or held by it in accordance with its standard retention policy.

(b)       Any Note(s) (or beneficial interests therein) that are acquired by the Issuer may be canceled upon the election of the Issuer to do so, provided , however , that no cancellation may be made between a Record Date and the next Payment Date. In order to effect such cancellation, the Issuer shall send to the Trustee a written notice that it owns such Note(s) (or beneficial interest(s)) and wishes to have the indicated principal amount thereof cancelled (which ownership the Issuer shall evidence to the satisfaction of the Trustee). Upon receipt of any such notice and satisfactory evidence, the Issuer hereby instructs the Trustee promptly to cause such principal amount to be cancelled (including, if applicable, to notify any applicable securities depository). Upon any such cancellation, the remaining unpaid principal amount of the Notes shall be reduced to take into effect such cancellation and the calculation of interest (and other calculations under this Indenture) shall take into effect such cancellation.

Section 2.15         Registration of Transfer and Exchange of Notes . (a) The Issuer hereby initially appoints the Security Registrar as transfer agent for the Notes. The Security Registrar shall register Notes and transfers and exchanges thereof as provided herein. The Security Registrar and each transfer agent and co-security registrar (if any) appointed with respect to the Notes shall be referred to collectively as the “ Transfer Agent .” The Security Registrar shall cause to be kept at the office or agency to be maintained by it in accordance with ‎ Section 8.11 a register (the “ Register ”) in which, subject to restrictions on transfer set forth herein, and such other reasonable regulations as it may prescribe, the Security Registrar shall provide for: (i) the registration of the Notes and (ii) the registration of transfers and exchanges of the Notes as provided herein. The Trustee shall preserve, in as current a form as is reasonably practicable, the names and addresses of Holders received by the Trustee.

(b)          Upon surrender for registration of transfer of any Note at the Corporate Trust Office or such other office or agency maintained by the Trustee in accordance with ‎ Section 8.11 , the Trustee shall authenticate and deliver, in the name of the designated transferee (and, if the transfer is for less than all of the applicable Note, the transferor), one or more new Note(s) executed by the Issuer in authorized denominations of a like aggregate principal balance and deliver such new Note(s) to the applicable Holder(s).

(c)         Every Note presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Trustee (or the applicable Transfer Agent) duly executed by the applicable Holder or its attorney duly authorized in writing.

(d)         No service charge shall be charged to a Holder for any registration of transfer or exchange of Notes, but the Trustee may require payment of a sum sufficient to cover any Tax or other governmental charge payable in connection therewith.

(e)          All Notes surrendered for registration of transfer or exchange shall be canceled and subsequently destroyed or retained by the Trustee in accordance with its standard retention policy.

In addition to the other provisions herein, the Issuer reserves the right to impose such transfer, certificate, exchange or other requirements, and to require such restrictive legends on a Note, as it may determine are necessary to ensure compliance with the securities laws of the United States and the states thereof and any other Applicable Laws.

(1)          at least 65% of the aggregate principal amount of the Notes originally issued under this Indenture on the Closing Date remain outstanding immediately after the occurrence of such redemption (excluding Notes held by the Issuer and its Subsidiaries); and

(2)          each such redemption occurs within 180 days of the date of the closing of any such Equity Offering.

At any time prior to May 23, 2023, the Issuer may on any one or more occasions redeem all or a part of the Notes, upon not less than 15 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, if any, to, the Redemption Date.

(ii)               Within 120 days after the end of each fiscal year of the Issuer ending after the date hereof, the Issuer shall deliver to the Trustee a certificate which need not comply with ‎ Section 10.12 , executed by the principal executive officer, the principal financial officer or the principal accounting officer of the Issuer and one other Authorized Officer of the Issuer, as to such officers’ knowledge of the Issuer’s compliance with all conditions and covenants under this Indenture, such compliance to be determined (solely for the purpose of this ‎ Section 4.1(b)(ii) ) without regard to any period of grace or requirement of notice under this Indenture.

(c)             Maintenance of Books and Records . The Issuer will, and will cause each of its Restricted Subsidiaries to, maintain books, accounts and other records in accordance, in all material respects, with GAAP and the Issuer will cause its Restricted Subsidiaries organized under laws of any other jurisdiction to maintain their books and records in accordance, in all material respects, with the generally accepted accounting principles of the applicable jurisdiction.

(d)             Further Assurances . The Issuer will, and will cause its Restricted Subsidiaries (including the Issuer) to, at its own cost and expense, execute and deliver to the Trustee all such other documents, instruments and agreements and do all such other acts and things as may be reasonably necessary in order to give effect to this Indenture or the Notes.

(e)             Singapore Listing . Approval in principle has been received from the SGX-ST to list the Notes on the SGX-ST and the Issuer will use its reasonable best efforts to obtain and maintain listing of the Notes on the SGX-ST.

(f)             Limitation on Indebtedness . (1) The Issuer will not, and will not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness; provided , however , that the Issuer or any Restricted Subsidiary may Incur Indebtedness if (i) on the date of such Incurrence and after giving effect thereto and the application of proceeds therefrom, the Consolidated Interest Coverage Ratio would be no less than 2.50:1.0 and the Consolidated Net Debt to Consolidated Adjusted EBITDA Ratio would be no greater than (x) if such Incurrence is on or prior to February 15, 2021, 3.50:1.0, (y) if such Incurrence is after February 15, 2021 and on or prior to February 15, 2022, 3.00:1.00 and (z) if such Incurrence is after February 15, 2022, 2.75:1.00 and, (ii) no Default or Event of Default shall have occurred and be continuing; and

(2)           Notwithstanding the foregoing clause (1) , the Issuer and its Restricted Subsidiaries may Incur the following Indebtedness:

For purposes of determining the compliance with this covenant:

(3)       Notwithstanding the foregoing, the Issuer may not Incur any Indebtedness pursuant to clause (2) above if the proceeds thereof are used, directly or indirectly, to Refinance any Subordinated Obligations, unless such Indebtedness will be subordinated to any obligations owed under the Notes and the Indenture to at least the same extent as such Subordinated Obligations.

For purposes of determining compliance with any Dollar-denominated restriction on the Incurrence of Indebtedness, the Dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred; provided , however , that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable Dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such Dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Issuer or any Restricted Subsidiary may Incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

Accrual of interest, accrual of dividends, payment of interest in the form of additional Indebtedness, payment of dividends in the form of shares of Preferred Stock, accretion or amortization of original issue discount will not be deemed to be an Incurrence of Indebtedness for purposes of this covenant.

(g)         Limitation on Liens . The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, create, Incur or suffer to exist any Lien on any property, assets, income or profits of the Issuer or any Restricted Subsidiary without effectively providing that the Notes (together with, if the Issuer so determines, any other Indebtedness or obligation then existing or thereafter created ranking equally with the Notes) shall be secured equally and ratably with (or prior to) the Indebtedness secured by such Lien so long as such Indebtedness shall be so secured, except that the foregoing provisions shall not apply to:

(1)       Liens in existence on the Closing Date;

(2)       Liens that secure Indebtedness owing by a Restricted Subsidiary to the Issuer and/or one or more other Restricted Subsidiaries or by the Issuer to one or more Restricted Subsidiaries;

(4)       any Lien on any property or assets existing at the time of acquisition thereof, including any acquisition by means of a merger or consolidation, and that is not created as a result of or in connection with or in anticipation of such acquisition (unless such Lien was created to secure or provide for the payment of any part of the purchase price of such property or assets); provided , however , that such Liens may not extend to any other property, assets, income or profits of the Issuer or any Restricted Subsidiary (other than improvements, accessions, upgrades, accessories and products and proceeds in respect of the property subject to such Liens at the time of such acquisition);

(5)       any Lien on the Capital Stock of an Unrestricted Subsidiary;

(6)       Liens (including extensions and renewals) with respect to Purchase Money Obligations and Capitalized Lease Obligations incurred pursuant to clause (2)(g) under ‎ Section 4.1(f) hereof;

(9)       Liens on the property or assets of the Issuer or any Restricted Subsidiary Incurred in the ordinary course of business to secure the performance of tenders, bids, statutory obligations, appeal bonds and deposits (including, without limitation, as security for contested taxes or import or customs duties), government contracts, workers compensation, unemployment insurance and social security claims, return-of-money bonds, or other obligation of a like nature and Incurred in a manner consistent with industry practice, in each case which are (i) not Incurred in connection with the borrowing of money, the obtaining of advances or credit or the payment of the deferred purchase price of property or assets in the operation of the business of the Issuer and the Restricted Subsidiaries, and (ii) not obligations of the type referred to in clause (2)(l) under ‎ Section 4.1(f) hereof;

The Fair Market Value of any cash Restricted Payment shall be its face amount. The Fair Market Value of any non-cash Restricted Payment or non-cash properties received in respect of the sale or issuance of Capital Stock, shall be determined by the management of the Issuer acting in good faith.

(i)       Limitation on Sale of Assets .

(1)     The Issuer will not, and will not permit any Restricted Subsidiary to, make any Asset Disposition unless:

(2)          Following the application of such Net Available Cash pursuant to clauses (1)(C)(i) , (ii) or (iii) above, the amount of Net Available Cash shall be reset at zero and the Issuer or the Restricted Subsidiary shall be entitled to use any remaining proceeds for any corporate purposes to the extent permitted under the Indenture.

(j)          Limitation on Sale and Lease-Back Transactions . The Issuer will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Lease-Back Transaction unless:

(k)        Limitation on Transactions with Affiliates .

The foregoing provisions will not apply to the following:

Whether or not required by the SEC, so long as any notes are outstanding, the Issuer will file with the SEC for public availability within the time periods specified in the SEC’s rules and regulations taking into account any extension of time, deemed filing date or safe harbor contemplated or provided for by Rule 12b-25, Rule 13a-11(c), and Rule 15d-11(c) under the Exchange Act, or General Instruction I.A.3(b) of Form S-3 under the Securities Act, and successor provisions (unless the SEC will not accept such a filing, in which case the Issuer will furnish to the Trustee and, upon its prior request, to any Holder of notes, within five days of the time period otherwise required for submission as specified in the SEC’s rules and regulations):

(1)             all quarterly and annual financial and hydrocarbon proved reserve information with respect to the Issuer and its Subsidiaries that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Issuer were required to file such Forms, including a “ Management’s Discussion and Analysis of Financial Condition and Results of Operations ” and, with respect to the annual information only, a report on the annual financial statements by the Issuer’s certified independent accountants; and

(2)             all current reports that would be required to be filed with the SEC on Form 8-K if the Issuer were required to file such reports.

The availability of the foregoing reports on the SEC’s EDGAR filing system will be deemed to satisfy the foregoing delivery requirements.

Notwithstanding the foregoing requirement, if the Issuer (which, for this purpose, includes its successor by merger, amalgamation, combination or acquisition) is no longer required to file reports with the SEC under Section 13 or Section 15(d) of the Exchange Act and it is required to file reports or documents with any securities regulatory authority in Canada (by virtue of being a “ reporting issuer ”) or with the UK Listing Authority or another foreign governmental agency or self-regulatory organization in the United Kingdom, then the Issuer will not be required to file with the SEC as described above but required to file corresponding information under regulations then applicable to the Issuer with the appropriate governmental authority in Canada or the United Kingdom, as applicable.

In addition, the Issuer and the Restricted Subsidiaries agree that, for so long as any notes remain outstanding and are “ restricted securities ” within the meaning of Rule 144(a)(3), if at any time they are not required to file the reports required by the preceding paragraphs with the SEC, they will furnish to the holders of the Notes and to securities analysts and prospective investors in the Notes, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. The Issuer and the Restricted Subsidiaries will be deemed to have provided such information to the holders of the Notes, securities analysts and prospective holders of the Notes if the Issuer (which for this purpose, includes its successor by merger, amalgamation, combination or acquisition) has (i) if required to file reports with the SEC, publicly filed reports containing such information via the EDGAR filing system (or successor system) and makes such reports publicly available on the Issuer’s website, (ii) if required to file reports or documents with any securities regulatory authority in Canada (by virtue of being a “ reporting issuer ”), publicly files reports containing such information via the SEDAR filing system (or successor system), or (iii) if required to file reports with the UK Listing Authority or another foreign governmental agency or self-regulatory organization in the United Kingdom, publicly files reports containing such information with the appropriate governmental agency and makes such reports publicly available on the Issuer’s website.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such reports, information or documents 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 under this Indenture (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate).

The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Issuer’s compliance with the covenants in this Indenture with respect to the furnishing or posting of such reports, information and documents filed with the SEC or EDGAR or on a website or any online data system under the Indenture.

(n)             Maintenance of Existence and Properties . The Issuer will, and will cause each of its Restricted Subsidiaries to (i) maintain in effect its corporate or limited liability company or partnership or other organizational existence and all registrations necessary therefor; (ii) take all reasonable actions to maintain all rights, privileges, titles to Property, franchises and the like necessary or desirable in the normal conduct of its business, activities or operations; and (iii) keep all its material Property used or useful for the operation of its business in good working order or condition (subject to ordinary wear and tear); provided , that the foregoing paragraphs ‎ (i) , ‎ (ii) and ‎ (iii) shall not require the Issuer to preserve the existence of any Restricted Subsidiary or maintain any such right, privilege, title to Property, license or franchise or Property if the senior management of the Issuer shall determine in good faith that (i) the maintenance or preservation thereof is no longer necessary or desirable in the conduct of the business of the Issuer and (ii) the non-maintenance or non-preservation thereof would not be reasonably expected to have a Material Adverse Effect.

(o)             [Reserved ]

(p)             Payment of Taxes and Claims . Except to the extent failure to do so would not be reasonably expected to have a Material Adverse Effect, the Issuer will, and will cause each of its Subsidiaries to, pay all material taxes, assessments and other governmental charges imposed upon it or any of its Property in respect of any of its franchises, businesses, income or profits before any penalty or interest accrues thereon, and pay all claims (including claims for labor, services, materials and supplies) for amounts which have become due and payable and which by law have or might become a Lien upon its Property, except if such charge or claim is being contested in good faith by appropriate provision promptly initiated and diligently conducted and if such reserves or other appropriate provision, if any, as shall be required by GAAP shall have been made therefore.

(q)             [Reserved.]

(r)             [Reserved].

(s)             Limitation on Line of Business . The Issuer will not, and will not permit any Restricted Subsidiary, to engage in any business other than a Related Business.

Section 4.2             Covenant Suspension . During any period of time that: (a) the Notes have an Investment Grade Rating from at least two Rating Agencies and (b) no Default or Event of Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses ‎(a) and ‎(b) being collectively referred to as a “ Covenant Suspension Event ”), the Issuer and its Restricted Subsidiaries will not be subject to the provisions of ‎ Section 4.1(f) , ‎ Section 4.1(h) , ‎ Section 4.1(i) (except in respect of Asset Sales in connection with Sale and Lease-Back Transactions), ‎ Section 4.1(k) , ‎ Section 4.1(l) and clause (4) of ‎ Section 4.3 (collectively, the “ Suspended Covenants ”).

Upon the occurrence of a Covenant Suspension Event, the amount of Net Available Cash Proceeds that has not been invested or applied as provided under ‎ Section 4.1(i) hereof shall be set at zero as of such date (the “ Suspension Date ”). In the event that, on any date subsequent to any Suspension Date (the “ Reversion Date ”), the Rating Agencies withdraw their Investment Grade Rating or downgrade such rating to below an Investment Grade Rating, or a Default or Event of Default occurs and is continuing, then the Issuer and its Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants with respect to future events. The period of time between the Suspension Date and the Reversion Date is referred to in this description as the “ Suspension Period .” Notwithstanding the reinstatement of the Suspended Covenants, no Default or Event of Default will be deemed to have occurred as a result of a failure to comply with the Suspended Covenants during the Suspension Period (or upon termination of the Suspension Period or after that time based solely on events that occurred and were completed during the Suspension Period).

On the Reversion Date all Indebtedness incurred during the Suspension Period and outstanding on the Reversion Date will be classified as having been incurred or issued pursuant to ‎ Section 4.1(f) hereof (to the extent such Indebtedness would be permitted to be incurred or issued thereunder as of the Reversion Date and after giving effect to Indebtedness incurred or issued prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness would not be so permitted to be incurred or issued pursuant to ‎ Section 4.1(f) hereof such Indebtedness will be deemed to have been outstanding on the Closing Date, so that it is classified as permitted under clause (2)(b) of ‎ Section 4.1(f) hereof. Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under ‎ Section 4.1(h) will be made as though the covenant described under ‎ Section 4.1(h) hereof had been in effect since the Closing Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will reduce the amount available to be made as Restricted Payments under the first paragraph of ‎ Section 4.1(h) hereof.

The Issuer shall give the Trustee written notice of any Covenant Suspension Event and in any event not later than five (5) Business Days after such Covenant Suspension Event has occurred. In the absence of such notice, the Trustee shall assume the Suspended Covenants apply and are in full force and effect. The Issuer shall give the Trustee written notice of any occurrence of a Reversion Date not later than five (5) Business Days after such Reversion Date. After any such notice of the occurrence of a Reversion Date, the Trustee shall assume the Suspended Covenants apply and are in full force and effect.

Section 4.3             Consolidation, Merger, Conveyance, Sale or Lease . The Issuer will not consolidate with or merge with or into or wind up into (whether or not the Issuer is the surviving corporation), or sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of its properties and assets, in one or more related transactions, to any Person unless:

In addition, the Issuer will not permit any Note Guarantor to consolidate with or merge with or into or wind up into (other than any merger with or into or winding up into the Issuer or another Note Guarantor or to the extent the Note Guarantor is the surviving Person), or sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of its properties and assets, in one or more related transactions, to any Person (other than to the Issuer or another Note Guarantor) unless:

Subject to certain limitations described in the Indenture, the Successor Guarantor will succeed to, and be substituted for, such Note Guarantor under the Indenture and the Note Guarantee of such Note Guarantor.

Notwithstanding the foregoing, any Note Guarantor may merge with or into or transfer all or part of its properties and assets to a Note Guarantor or the Issuer or merge with a Restricted Subsidiary of the Issuer solely for the purpose of reincorporating the Note Guarantor in the jurisdiction of such Note Guarantor, the Cayman Islands, Canada, Colombia, the U.S., any state of the U.S. or the District of Columbia, or any other jurisdiction whose sovereign debt is rated BBB or higher by Standard & Poor’s Ratings Group, Inc. and Baa2 or higher by Moody’s Investors Service, Inc., so long as the amount of Indebtedness of such Note Guarantor and its Restricted Subsidiaries is not increased thereby, and the resulting entity remains or becomes a Note Guarantor to the extent otherwise required under the Indenture (a “ Reincorporation Transaction ”).

For purposes of this section, the sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the properties or assets of one or more Subsidiaries of the Issuer, which properties or assets, if held by the Issuer instead of such Subsidiaries, would constitute all or substantially all of the properties or assets of the Issuer on a consolidated basis, shall not be deemed to be the transfer of all or substantially all of the properties or assets of the Issuer so long as such transfer is to one or more Subsidiaries of the Issuer that are Restricted Subsidiaries. Any Subsidiary of the Issuer that is a Restricted Subsidiary may consolidate with, merge into or dispose of all or part of its properties or assets to the Issuer or to another Restricted Subsidiary that is a Subsidiary of the Issuer.

Upon any consolidation, combination or merger or any transfer of all or substantially all of the properties and assets of the Issuer’s or Guarantor’s, as the case may be, properties and assets substantially as an entirety (determined on a consolidated basis with its Restricted Subsidiaries) in accordance with this covenant, in which the Issuer or Guarantor, as the case may be, is not the continuing corporation, the Successor formed by such consolidation or into which the Issuer or Guarantor as the case may be, is merged or to which such conveyance, lease or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer or Guarantor, as the case may be, under the Indenture and the Notes with the same effect as if such Successor had been named as such, except in the case of a lease, and the Issuer or Guarantor, as the case may be, shall be discharged from all covenants and obligations under the Indenture and the Notes.

Furthermore, the Issuer may, without the consent of any Holder, be substituted by any Wholly Owned Subsidiary of the Issuer as principal debtor in respect of the Notes (in that capacity, the “ Substituted Issuer ”); provided that the following conditions are satisfied:

Upon the execution of the Issuer Substitution Documents, any substitute guarantees and compliance with the other conditions set forth above, the Substituted Issuer will be deemed to be named in the Notes as the principal debtor in place of the Issuer and the Issuer will be released from all of its obligations under the Notes and the Indenture as principal obligor (however will become a Notes Guarantor).

Not later than 10 Business Days after the execution of the Issuer Substitution Documents, the Substituted Issuer will give notice thereof to the Holders.

Notwithstanding any other provision of the Indenture, the Issuer will do or cause to be done all acts and things and promptly execute and deliver any documents or instruments, including any substitute guarantees and an Opinion of Counsel of internationally recognized U.S. counsel, that may be required to ensure that the Guarantors’ guarantees are in full force and effect for the benefit of the Holders and beneficial owners of the Notes following the substitution described above.

Section 4.4             Repurchases at the Option of the Holders Upon a Change of Control . If a Change of Control occurs, each Holder will have the right to require the Issuer to repurchase all or any part (equal to at least $200,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to a Change of Control Offer (as defined below) on the terms set forth in the Indenture. No such purchase in part shall reduce the Outstanding principal amount at maturity of the Notes held by any Holder to below $200,000. In the Change of Control Offer, the Issuer will offer a “ Change of Control 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 (subject to the right of the Holders of record on the relevant Record Date to receive interest and Additional Amounts, if any, on the relevant interest Payment Date).

Within 30 days following any Change of Control, the Issuer will make a “ Change of Control Offer ” by giving notice to the Trustee and each Holder of Notes by mailing and publishing such notice in accordance with ‎ Section 10.6 below, describing the transaction or transactions that constitute the Change of Control, the Change of Control and offering to repurchase Notes on the date specified in the notice (the “ Change of Control Payment Date ”), which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedure required by the Indenture and described in such notice.

The Issuer will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other applicable securities laws or regulations in connection with the repurchase of Notes pursuant to this covenant. To the extent that the provisions of any applicable securities laws or regulations conflict with provisions of this covenant, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of its compliance with such securities laws or regulations.

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

The Paying Agent under the Indenture will promptly mail each Holder of Notes properly tendered the Change of Control Payment for such Notes, and, upon receipt of a written order, the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided , however , that each new Note will be in a principal amount of $200,000 or an integral multiple of $1,000 in excess thereof. The Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

The provisions described above that require the Issuer to make a Change of Control Offer following a Change of Control shall apply whether or not any other provisions of the Indenture are applicable. Except as described above with respect to a Change of Control, the Indenture does not contain provisions that permit the Holders of the Notes to require that the Issuer repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

The Issuer will not be required to make a Change of Control Offer upon a Change of Control if 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 the Indenture, that are applicable to a Change of Control Offer made by the Issuer and such third party purchases all Notes properly tendered and not withdrawn under the Change of Control Offer.

If an Event of Default (other than an Event of Default specified in ‎ Section 5.1(a)(vii) and ‎ (viii) with respect to the Issuer or the Issuer) occurs and is continuing, then in every such case either the Trustee acting at the written direction of Holders of not less than 25% in aggregate principal amount of the Outstanding Notes or the Holders of not less than 25% in aggregate principal amount of the Outstanding Notes, may declare the principal amount of the Outstanding Notes to be due and payable immediately (including all Additional Amounts thereon), by a notice in writing to the Issuer (and to the Trustee if given by Holders), and upon any such declaration such principal amount shall become immediately due and payable.

If an Event of Default described in ‎ Section 5.1(a)(vii) or ‎ (viii) with respect to the Issuer occurs and is continuing, then and in every such case, the principal amount of all the Notes, together with all accrued interest thereon, shall, without any notice to the Issuer or any other act on the part of the Trustee or any Holder, become and be immediately due and payable.

At any time after such a declaration of acceleration with respect to the Notes has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as provided in this Article, the Required Holders, by written notice delivered to the Issuer and the Trustee, may rescind and annul such declaration and its consequences if:

(i)              the Issuer has paid or deposited with the Trustee and/or any Paying Agents a sum sufficient to pay (A) all overdue interest, if any, on all Notes, (B) the principal of (and premium, if any, on) any Notes which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Notes, (C) to the extent that payment of such interest is lawful, interest upon any overdue interest at the rate or rates prescribed therefor in such Notes, and (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and

(ii)             all Events of Default with respect to the Notes, other than the non- payment of the principal of and accrued interest on the Notes which have become due solely by such declaration of acceleration, have been cured or waived as provided in clause (m) below.

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

(c)             Collection of Indebtedness and Suits for Enforcement by Trustee . The Issuer covenants that if: (i) Default is made in the payment of any interest on any Note when such interest becomes due and payable and such Default continues for a period of 30 days, or (ii) Default is made in the payment of the principal of (or premium, if any, on) any Note at the maturity thereof, the Issuer will pay to the Trustee, for the benefit of the Holders, the whole amount then due and payable on such Notes for principal (and premium, if any) and interest, if any, and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and on any overdue interest, at the rate or rates prescribed therefor in such Notes, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. If the Issuer fails to pay such amount forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Issuer or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the Property of the Issuer or any other obligor upon such Notes, wherever situated.

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

(d)             Trustee May File Proofs of Claim . In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, administrative take-over, adjustment, composition or other judicial proceeding relative to the Issuer or the material Property of the Issuer or its creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Issuer for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(i)                  to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agent and counsel and any other amounts due to the Trustee under Section 8.5 ) and of the Holders allowed in such judicial proceedings; and

(ii)               to collect and receive any moneys or other Property payable or deliverable on any such claims and to distribute the same in accordance with the terms hereof; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee.

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, 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.

(e)             Trustee May Enforce Claims Without Possession of Notes . To the extent permitted under Applicable Law, all rights of action (including without limitation the right to file proofs of claim) under this Indenture may be enforced by the Trustee without the possession of any of the Notes or the production thereof in any trial or other proceeding relating thereto. Any suit or proceeding instituted by the Trustee shall be brought in its name as Trustee without the necessity of joining any Holders as plaintiffs or defendants. Any recovery of judgment shall be for the benefit of the Holders, subject to the provisions of this Indenture.

(f)             Application of Money Collected . Any monies collected by the Trustee pursuant to this ‎ Section 5.1 or otherwise received by the Trustee, and after an Event of Default any money or other properties distributable in respect of the Issuer’s obligations under this Indenture, shall be applied (i) first , to the Trustee and the Authorized Agents in payment of all amounts due hereunder, (ii) second , to the payment of interest accrued on the Notes and any premium and Additional Amounts thereon, (iii) third , to the payment of the outstanding principal amount of the Notes and (iv) fourth , to the Issuer. The Trustee may fix a record date and payment date for any payment by it to Holders pursuant to this Section.

(g)             Rights and Remedies of Holders . A Holder shall not have any right to institute any suit, action or proceeding for the enforcement of this Indenture, or for the exercise of any other remedy hereunder unless (i) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Notes, (ii) Holders of more than twenty-five percent (25%) in aggregate principal amount of Outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee thereunder, (iii) such Holder or Holders have offered to the Trustee indemnity satisfactory to it against the costs, expenses and liabilities to be Incurred in compliance with such request, (iv) the Trustee during the 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding, and (v) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Required Holders; provided , however , that no one or more Holders shall have any right to affect, disturb or prejudice in any manner whatsoever the benefit of this Indenture afforded the Notes by its or their action (provided, that the Trustee does not have an affirmative duty to ascertain whether or not any such action is unduly prejudicial to such Notes), or to enforce, except in the manner provided herein, any remedy, right or power hereunder. Any suit, action or proceeding shall be instituted and maintained in the manner provided herein for the benefit of the Holders of all Outstanding Notes.

(h)             Unconditional Right of Holders to Receive Principal, Premium and Interest . Notwithstanding any other provision in this Indenture, any Holder shall have the right which is absolute and unconditional, to receive payment of the principal of (and premium and Additional Amounts, if any) and interest, if any, on such Note on the dates specified in the Notes as the fixed date on which the principal of such Note or any installment of interest on such Note is due and payable (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

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

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

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

(l)             Control by Holders . The Required Holders shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Notes; provided , however , that (i) such direction shall not be in conflict with any rule of law or with this Indenture or subject the Trustee to personal liability, (ii) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction, and (iii) the Trustee shall have received indemnity or security satisfactory to it against the costs, expenses and liability incurred in connection therewith.

Subject to ‎ Section 5.1(b) , the Required Holders may, on behalf of all Holders, waive any past Default hereunder and its consequences, except a Default (i) in the payment of the principal of (or premium, if any) or interest, if any, on any Note, or (ii) in respect of a covenant or provision hereof that cannot be modified or amended without the consent of the Holder of each Outstanding Note affected. 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 under this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

(n)            Undertaking for Costs . All parties to this Indenture agree, and each Holder by its acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this clause shall not apply to any suit instituted by the Trustee, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest, if any, on any Note on or after the dates specified in the Notes as the fixed date on which the principal of such Note or any installment of interest on such Note is due and payable (or, in the case of redemption, on or after the Redemption Date).

Article VII
GUARANTY

Section 7.1             Guaranty . Subject to the provisions of this Article, the Note Guarantors hereby absolutely, irrevocably and unconditionally Guarantee, jointly and severally, to each Holder and to the Trustee the full and punctual payment (whether at an installment date or the Maturity Date, upon redemption, purchase pursuant to an offer to purchase or acceleration or otherwise) of the principal, premium, interest and all other amounts that may come due and payable under each Note and the full and punctual payment of all other amounts payable by the Issuer under this Indenture as they come due. Upon failure by the Issuer to pay punctually any such amount, each of the Note Guarantors shall, without duplication, forthwith pay the amount not so paid at the place and time and in the manner specified in this Indenture. This Guaranty constitutes a direct, joint and several, general and unconditional primary obligation of each Note Guarantor which will at all times rank at least pari passu with all other present and future senior unsecured obligations of such Guarantor, except for such obligations as may be preferred by provisions of law that are both mandatory and of general application.

Section 7.2             Guaranty Unconditional . To the extent permitted by Applicable Law, the obligations of the Note Guarantors hereunder are unconditional and absolute and, without limiting the generality of the foregoing, will not be released, discharged or otherwise affected by:

(a)             any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of the Issuer under this Indenture or any Note, by operation of law or otherwise;

(b)             any modification or amendment of or supplement to this Indenture or any Note;

(c)             any change in the corporate existence, structure or ownership of the Issuer, or any insolvency, bankruptcy, reorganization, plan of arrangement or other similar proceeding affecting the Issuer or its assets or any resulting release or discharge of any obligation of the Issuer contained in this Indenture or any Note;

(d)             the existence of any claim, set-off or other rights which any of the Note Guarantors may have at any time against the Issuer, the Trustee or any other Person, whether in connection with this Indenture or any unrelated transactions, provided that nothing herein prevents the assertion of any such claim by separate suit or compulsory counterclaim;

(e)             any invalidity or unenforceability relating to or against the Issuer for any reason of this Indenture or any Note, or any provision of applicable law or regulation purporting to prohibit the payment by the Issuer of the principal of or interest on any Note or any other amount payable by the Issuer under this Indenture;

(f)             any other act or omission to act or delay of any kind by the Issuer, the Trustee or any other Person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to any of the Note Guarantors’ obligations hereunder; or

(g)             any defenses (other than full and unconditional payment) or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms of the Guaranty or this Indenture.

Section 7.3             Discharge; Reinstatement . The Note Guarantors’ obligations hereunder will remain in full force and effect until either (a) such Guarantor has been released as provided hereunder or (b) the principal of, premium (if any), and interest on the Notes and all other amounts payable by the Issuer under this Indenture have been indefeasibly paid in full. If at any time any payment of the principal of, premium, if any, or interest on any Note or any other amount payable by the Issuer under this Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy, arrangement or reorganization of the Issuer or otherwise, the Note Guarantors’ obligations hereunder with respect to such payment will be reinstated as though such payment had been due but not made at such time.

Section 7.4             Waiver by the Note Guarantors . (a) To the extent permitted by Applicable Law, each of the Note Guarantors unconditionally and irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Issuer or any other Person. The Guaranty constitutes a Guarantee of payment and not of collection.

(b)             To the extent permitted by Applicable Law, each of the Note Guarantors expressly waives irrevocably and unconditionally:

(i)              Any right it may have to first require any Holder of the Notes to proceed against, initiate any actions before a court of law or any other judge or authority, or enforce any other rights or security or claim payment from the Issuer or any other Person (including any Guarantor or any other guarantor) before claiming it under this Indenture;

(ii)             Any right to which it may be entitled to have the assets of the Issuer or any other Person (including any Guarantor or any other guarantor) first be used, applied or depleted as payment of the Issuer’s or the Note Guarantors’ obligations hereunder, prior to any amount being claimed from or paid by any of the Note Guarantors hereunder; and

(iii)            Any right to which it may be entitled to have claims hereunder divided between the Note Guarantors.

Section 7.5             Subrogation and Contribution . Upon making any payment with respect to any obligation of the Issuer under this Article, each paying Guarantor will be subrogated to the rights of the payee against the Issuer with respect to such obligation; provided , however , that such Guarantor shall not be entitled to enforce, or to receive any payments arising out of or based upon, such right of subrogation until the principal of (and premium, if any) interest, Additional Amounts on all Notes and any other amounts due under this Indenture shall have been paid in full.

Section 7.6             Stay of Acceleration . If acceleration of the time for payment of any amount payable by the Issuer under this Indenture or the Notes is stayed upon the insolvency, bankruptcy or reorganization of the Issuer, all such amounts otherwise subject to acceleration under the terms of this Indenture are nonetheless payable by the Note Guarantors forthwith on demand by the Trustee.

Section 7.7             Execution and Delivery of Guaranty . The execution by each of the Note Guarantors of this Indenture evidences the Guaranty of such Guarantor, whether or not the person signing as an officer of such Guarantor still holds that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Guaranty set forth in this Indenture on behalf of each Guarantor.

Section 7.8             Purpose of Guaranty . The Issuer and the Trustee hereby acknowledge that the purpose and intent of each of the Note Guarantors in executing this Indenture and providing the Guaranty is to give effect to the agreement of such Guarantor to Guarantee the payment of any such amounts due by the Issuer under the Notes and this Indenture, whether such amounts are in respect of principal, interest or any other amounts (including Additional Amounts). Therefore, each of the Note Guarantors agrees that if the Issuer shall fail to pay in full when due (whether at stated maturity, by acceleration or otherwise) any principal, interest or any other amounts (including Additional Amounts) with respect to this Indenture and the Notes, such Guarantor shall promptly pay the same, without any demand or notice whatsoever.

(b)            To be entitled to vote at any meeting of Holders, a Person shall be a Holder or a Person duly appointed by an instrument in writing as proxy for a Holder. The quorum at any meeting of Holders called to adopt a resolution shall be Holders holding not less than 50% in aggregate principal amount of the Outstanding Notes.

Article X
MISCELLANEOUS

Section 10.1           Payments; Currency Indemnity . (a) Except to the extent otherwise stated herein, each payment to be made hereunder or on any Note shall be made on the required payment date in Dollars and in immediately available funds at the office of the Trustee specified in ‎ Section 10.6 or to such other office or account as may be specified by any party in a notice to the applicable sender of such payment.

(b)            Except to the extent otherwise stated, Dollars are the sole currency of payment for all sums payable by the Issuer or the Guarantor under or in connection with this Indenture or any Note, including with respect to indemnities. Any amount received or recovered in a currency other than Dollars (whether as a result of, or of the enforcement of, a judgment, decree or order of a court of any jurisdiction, in the winding-up or dissolution of the Issuer or otherwise) in respect of any sum expressed to be due on the Notes and under this Indenture shall only constitute a discharge of such obligation to the extent of the amount of Dollars that the payee of such amounts due is able to purchase in accordance with normal banking or other normal currency exchange procedures with the amount so received or recovered in that other currency on the date of that receipt or recovery (or, if it is not practicable to make that purchase on that date, on the first date on which it is practicable to do so). If such amount of Dollars is more than the amount expressed to be due on the Notes or under this Indenture, if applicable, then the payee shall reimburse such excess to the Issuer or Guarantor. If such amount of Dollars is less than the amount expressed to be due on the Notes or under this Indenture, if applicable, then the Issuer or Guarantor shall indemnify the payee of such amounts against any loss sustained by it as a result. In any event, the Issuer or Guarantor shall indemnify the payee of such amounts against the cost of making any such purchase. For the purposes of this ‎ Section 9.1(b) , in the event the payee finds it impracticable to make a purchase on the date it receives the payment in a currency other than in Dollars, it will be sufficient for the payee of such amounts to certify in a reasonable manner (indicating the sources of information used) that it would have suffered a loss had an actual purchase of Dollars been made with the amount so received in such other currency on the date of receipt or recovery. These indemnities constitute a separate and independent obligation from the other obligations hereunder, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by such payee and shall continue in full force and effect despite any other judgment, order, claim or proof for a liquidated amount in respect of any amount due hereunder or under any Note.
