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

The ownership of Notes shall be proved by the Note Register.

Any request, demand, authorization, direction, notice, consent, waiver or other action of the Holder of any Note, whether taken pursuant to a meeting of Holders or pursuant to an Act of Holders, shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Note.

The Company may, in accordance with applicable provisions of Argentine law, if any, set any day as a record date for the purpose of determining the Holders of Outstanding Notes of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Notes of such series; provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding Notes of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date (as defined below) by Holders of the requisite principal amount of Outstanding Notes of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Notes of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Notes of the relevant series in the manner set forth in Section 1.6.

Exhibit 2.4.2 - 32

The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Notes of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 5.2, (iii) any request to institute proceedings referred to in Section 5.7 or (iv) any direction referred to in Section 5.12, in each case with respect to Notes of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Notes of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Notes of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Notes of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Notes of the relevant series in the manner set forth in Section 1.6.

With respect to any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Notes of the relevant series in the manner set forth in Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto that set such record date shall be deemed to have initially designated the 180^th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180^th day after the applicable record date.

In addition, record dates for a Global Note may be set in accordance with the Applicable Procedures of the Depositary.

Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

1.6	Notice to Holders; Waiver

Where this Indenture provides for notice to Holders (other than any Holder whose address, as it appears in the Note Register, is located in Argentina) of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed by U.S. first-class postage prepaid, to each Holder affected by such event, at his or her address as it appears in the Note Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed hereunder or in the terms of the relevant Notes for the giving of such notice; provided that, to the extent such notice is delivered before 3:00 p.m. New York time, the day in which such notice is delivered shall be the first day of the relevant time period. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

Notice to Holders whose addresses, as they appear in the Note Register, are located in Argentina shall be deemed to have been duly given if made in accordance with the methods described in clauses (i), (iii) or (iv) of the following sentence. Notice to Holders shall also be published as follows: (i) in a leading newspaper having general circulation in Buenos Aires, Argentina (which is expected to be La Nación, El Cronista Comercial or Ámbito Financiero) and, to the extent required by Argentine law, in the Official Gazette of Argentina; (ii) as long as any Notes of the relevant series are listed and traded on the ▇▇▇▇ and A3 Mercados, and the rules of such exchanges so require, in the Daily Bulletin of ▇▇▇▇’▇ Informative Bulletin and in the Electronic Bulleting of the A3 Mercados, respectively; (iii) as long as any Notes of the relevant series are listedon any other stock exchange, as required by such stock exchange; and (iv) in any other manner required by the provisions of the Argentine Negotiable Obligations Law.

In case by reason of the suspension or irregularities of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Where this Indenture provides for notice of any event to a Holder of a Global Note, such notice shall be sufficiently given if given to the Depositary for such Note (or its designee), pursuant to its Applicable Procedures, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice; provided that, to the extent such notice is delivered before 3:00 p.m. New York time, the day in which such notice is delivered shall be the first day of the relevant time period.

Notice to be given by any Holder shall be in writing and given by forwarding the same to the Trustee or Paying Agent. With respect to any Notes that are represented by a Global Note, such notice may be given by any owner of an interest in such Global Note to the Trustee or any such Paying Agent via DTC in such manner as the Trustee or Paying Agent, as the case may be, and DTC may approve for such purpose.

Exhibit 2.4.2 - 34

The Trustee, the Co-Registrar, the Registrar, any Paying Agent, any Transfer Agent or any agent of any of such entities may conclusively rely on the records of DTC, Euroclear, Clearstream or Luxembourg, as applicable, as to the identity of owners of beneficial interests in each Global Note and the principal amounts beneficially owned.

The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

1.8	Successors and Assigns

All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not.

1.9	Separability Clause

In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

1.10	Benefits of Indenture

Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

1.11	Governing Law

The Argentine Negotiable Obligations Law shall govern the requirements for the Notes to qualify as obligaciones negociables (“negotiable obligations”) thereunder. The Argentine Negotiable Obligations Law, together with the Argentine Companies Law No. 19,550, as amended, the Public Offering Law 17,811, the Argentine Law No. 26,831, Federal Resolution No. 622/13 issued by the CNV as amended and supplemented (the “CNV Rules”) and other applicable Argentine laws and regulations shall govern the Company’s capacity and corporate authorization to execute and deliver the Notes, the public offering of the Notes in Argentina, matters relating to meetings of Holders and the statute of limitations. All other matters with respect to the Notes and this Indenture including, without limitation, the rights, powers, duties, and protections of CSC Delaware Trust Company, shall be governed by, and construed in accordance with, the laws of the State of New York, United States of America.

1.12	Legal Holidays

If a payment date for the Notes falls on a day that is not a Business Day, payment of principal (and premium, if any) and interest with respect to such Notes will be made on the next succeeding Business Date with the same force and effect as if made on the due date and no interest on such payment will accrue from and after such due date. Postponement of this kind will not result in a default under the Notes or the Indenture. No interest will accrue on the postponed amount from the original due date to the next Business Day.

1.13	Waiver of Jury Trial

EACH OF THE COMPANY, THE HOLDERS AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY.

Exhibit 2.4.2 - 35

1.14	Currency of Payment

U.S. dollars are the sole currency of account and payment for all sums payable under or in connection with amounts owed by the Company under the Notes.

Nothing in the Notes and this Indenture shall justify the Company in refusing to make payments under the Notes and this Indenture in U.S. dollars for any reason whatsoever, including, without limitation, any of the following: (i) the purchase of U.S. dollars in Argentina by any means becoming more onerous or burdensome for the Company than as of the date hereof and (ii) the exchange rate in force in Argentina increasing significantly from that in effect as of the date hereof. The Company waives the right to invoke any defense of payment impossibility (including any defense under Section 1091 of the Argentine Civil and Commercial Code), impossibility of paying in U.S. dollars (assuming liability for any force majeure or act of God), or similar defenses or principles (including, without limitation, equity or sharing of efforts principles).

Pursuant to Article 4 of the Argentine Negotiable Obligations Law, any payment under the Notes will be made solely and exclusively in U.S. Dollars, with no cancelling effect for any payment in any currency other than U.S. Dollars, in strict compliance with the provisions set forth in Article 765 of the Argentine Civil and Commercial Code, as amended by Decree No. 70/2023 (published in the Official Gazette on December 21, 2023) (the “Decree 70/23”). Should Article 765 of the Argentine Civil and Commercial Code revert to its pre-Decree 70/23 wording, the Company forever and irrevocably waives any right that might assist it to allege that any payments in connection with the Notes could be payable in any currency other than in U.S. dollars, and therefore waives and renounces to applicability thereof to any payments in connection with the Notes.

In the event that any restrictions or prohibition of access to the Argentine foreign exchange market exists, the Company shall seek to pay all amounts payable under the Notes either (i) by purchasing at market price securities of any series of U.S. dollar denominated Argentine sovereign bonds or any other securities or private or public bonds issued in Argentina, and transferring and selling such instruments outside Argentina, to the extent permitted by applicable law, or (ii) by means of any other reasonable means permitted by law in Argentina, in each case, on such payment date. All costs and taxes payable in connection with the procedures referred to in clauses (i) and (ii) above shall be borne by the Company.

1.15	Consent to Jurisdiction and Service of Process

The Company irrevocably consents to the non-exclusive jurisdiction of any court of the State of New York or any United States federal court sitting in the Borough of Manhattan, New York City, New York, United States, and any appellate court from any thereof, or any Argentine court sitting in Buenos Aires, Argentina, including the ordinary courts for commercial matters and, if the Notes are listed on the Bolsa, the Tribunal de Arbitraje General de la Bolsa de Comercio de Buenos Aires (Permanent Arbitral Tribunal of the Bolsa) under the provisions of the Argentine Capital Markets Law and waives any immunity from the jurisdiction of such courts over any suit, action or proceeding that may be brought in connection with this Indenture or the Notes. The Company irrevocably waives, to the fullest extent permitted by law, any objection to any such suit, action, or proceeding that may be brought in connection with this Indenture or the Notes in such courts whether on the grounds of venue, residence or domicile or on the ground that any such suit, action or proceeding has been brought in an inconvenient forum. The Company agrees that final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon the Company and may be enforced in any court to the jurisdiction of which the Company or its assets or properties is subject by a suit upon such judgment; provided, that service of process is effected upon the Company in the manner provided by this Indenture.

Exhibit 2.4.2 - 36

The Company agrees that service of all writs, process and summonses in any suit, action or proceeding brought in connection with this Indenture or the Notes against the Company (a) in any court of the State of New York or any United States federal court sitting in the Borough of Manhattan, New York City may be made upon C T Corporation System at ▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, whom the Company irrevocably appoints as its authorized agent for service of process and (b) in any competent court in Argentina or in the arbitrators’ tribunal of the Bolsa in Argentina, may be made at the Company’s legal domicile at ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇, ▇▇▇▇ ▇▇▇▇▇ (▇▇▇▇), ▇▇▇▇ ▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇. The Company represents and warrants that C T Corporation System has agreed to act as the Company’s agent for service of process. The Company agrees that such appointment shall be irrevocable so long as any of the Notes remain Outstanding or until the irrevocable appointment by the Company of a successor in the State of New York as its authorized agent for such purposes and the acceptance of such appointment by such successor. The Company further agrees to take any and all action, including the filing of any and all documents and instruments, which may be necessary to continue such appointment in full force and effect as aforesaid. If C T Corporation System shall cease to act as the Company’s agent for service of process, the Company shall appoint without delay another such agent and provide notice to the Trustee of such appointment. With respect to any such action in any court of the State of New York or any United States federal court in the Borough of Manhattan, New York City, service of process upon C T Corporation System, as the authorized agent for the Company for service of process and written notice of such service to the Company, shall be deemed, in every respect, effective service of process upon the Company.

Nothing in this Section shall affect the right of any party to serve legal process in any other manner permitted by law or affect the right of any party to bring any action or proceeding against any other party or its property in the courts of other jurisdictions.

1.16	Resignation and Appointment of Agents

The Company may terminate at any time the appointment of any or all of the Registrar, Co‑Registrar, Principal Paying Agent, and any Paying Agent and any Transfer Agent, with or without cause, by giving to the Registrar, Co‑Registrar, Principal Paying Agent, Paying Agent or the Transfer Agent, as the case may be, at least 90 days’ prior written notice to that effect; provided that (i) in the case of termination of the appointment of the Registrar or the Co-Registrar, no such notice shall take effect until a new Registrar or Co-Registrar, as the case may be, has been appointed and has accepted such appointment, and (ii) the effective date of such termination may not occur within 21 days before or after an Interest Payment Date nor during such time as an Event of Default shall have occurred and be continuing.

The Registrar, Co-Registrar, Principal Paying Agent, any Paying Agent, and any Transfer Agent may at any time resign from such capacities by giving written notice to the Company, specifying the date on which its desired resignation shall become effective; provided, however, that (i) such date shall never be less than 45 days from the date on which such notice is received by the Company, unless the Company agrees to accept less notice, (ii) the effective date of such resignation may not occur within 21 days before or after an Interest Payment Date and (iii) in any event, the resignation may not take effect prior to the appointment of a successor Registrar, Co-Registrar, Principal Paying Agent, Paying Agent or Transfer Agent, as the case may be, and the acceptance thereof of such appointment.

If the Registrar, Co-Registrar, Principal Paying Agent, any Paying Agent or any Transfer Agent, as the case may be, resigns or is removed and the Company has not appointed a successor agent within 15 days of the expiration of the relevant notice, then the relevant Registrar, Co-Registrar, Principal Paying Agent, Paying Agent, or Transfer Agent, as the case may be, may appoint, or may petition a court of competent jurisdiction for the appointment of, a reputable institution as the successor agent at the expense of the Company. Upon its removal or resignation, the Registrar, Co-Registrar, Principal Paying Agent, any Paying Agent or any Transfer Agent, as the case may be, shall be entitled to the payment by the Company of its compensation and indemnification for the services rendered hereunder.

(19)	any other terms of the series (which terms shall not be inconsistent with the provisions of this Indenture, except as permitted by Section 9.1(4)).

All Notes of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in or pursuant to the Board Resolution referred to above and (subject to Section 3.3) set forth, or determined in the manner provided, in the Officer’s Certificate referred to above or in any such indenture supplemental hereto.

If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Director of Legal and Regulatory Affairs of the Company or any Senior Counsel of the Company and delivered to the Trustee at or prior to the delivery of the Officer’s Certificate setting forth the terms of the series.

3.2	Denominations

The Notes of each series shall be issuable only in fully registered form without coupons and only in such denominations as shall be specified as contemplated by Section 3.1. In the absence of any such specified denomination with respect to the Notes of any series, the Notes of such series shall be issuable in denominations of US$1,000 and integral multiples of US$1,000 thereafter.

Exhibit 2.4.2 - 41

3.3	Execution, Authentication, Delivery and Dating

The Notes shall be executed on behalf of the Company by a director and a Statutory Auditor of the Company (the “Authorized Officers”). The signature of any of these officers on the Notes may be manual or facsimile, subject in the latter case to the receipt of any required approval by the CNV.

Notes bearing the manual or facsimile signatures of individuals who were at the time of execution of the Notes the proper Authorized Officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Notes.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Notes of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with the Company Order shall authenticate and deliver such Notes. If the form or terms of the Notes of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 2.1 and 3.1, in authenticating such Notes, and accepting the additional responsibilities under this Indenture in relation to such Notes, the Trustee shall receive, and (subject to Section 6.1) shall be fully protected in relying upon, an Opinion of Counsel stating:

(1)	if the form of such Notes has been established by or pursuant to Board Resolution as permitted by Section 2.1, that such form has been established in conformity with the provisions of this Indenture;

(2)	if the terms of such Notes have been established by or pursuant to Board Resolution as permitted by Section 3.1, that such terms have been established in conformity with the provisions of this Indenture; and

(3)

that such Notes, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, shall constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

If such form or terms have been so established, the Trustee shall not be required to authenticate such Notes if the issue of such Notes pursuant to this Indenture shall affect the Trustee’s own rights, duties or immunities under the Notes and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

Notwithstanding the provisions of Section 3.1 and of the preceding paragraph, if all Notes of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officer’s Certificate otherwise required pursuant to Section 3.1 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Note of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Note of such series to be issued; provided, however, that no such Opinion of Counsel shall be delivered with respect to the authentication and delivery of any Notes on the initial Issue Date.

Each Note shall be dated the date of its authentication.

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature of an authorized signatory of the Trustee, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Note shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Note to the Trustee for cancellation as provided in Section 3.10, for all purposes of this Indenture such Note shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

Exhibit 2.4.2 - 42

3.4	Temporary Notes

If permitted by Argentine law, pending the preparation of definitive Notes of any series, the Company may execute, and upon receipt of a Company Order the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the Authorized Officers executing such Notes may determine, as evidenced by their execution of such Notes.

If temporary Notes of any series are issued, the Company shall cause definitive Notes of that series to be prepared without unreasonable delay. After the preparation of definitive Notes of such series, the temporary Notes of such series shall be exchangeable for definitive Notes of such series upon surrender of the temporary Notes of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Notes of the same series, of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged, the temporary Notes of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Notes of such series and tenor.

3.5	Global Notes

(a)

Each Global Note authenticated under this Indenture shall be registered in the name of the Depositary designated by the Company for such Global Note or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Note shall constitute a single Note for all purposes of this Indenture.

(b)

Notwithstanding any other provision in this Indenture, no Global Note may be exchanged in whole or in part for Notes registered, and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Note or a nominee thereof unless (i) such Depositary (A) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Note or (B) has ceased to be a clearing agency registered as such under the Exchange Act, or (ii) there shall have occurred and be continuing an Event of Default with respect to such Global Note, and, in the case of both (i) and (ii), the Company executes and delivers to the Trustee a Company Order stating that all Global Notes shall be exchanged in whole for Notes that are not Global Notes (in which case such exchange shall be effected by the Trustee).

Exhibit 2.4.2 - 43

(c)

If any Global Note is to be exchanged for other Notes or cancelled in whole, it shall be surrendered by or on behalf of the Depositary or its nominee to the Trustee, as Co-Registrar, for exchange or cancellation as provided in this Article Three. If any Global Note is to be exchanged for other Notes or cancelled in part, or if another Note is to be exchanged in whole or in part for a beneficial interest in any Global Note, then either (i) such Global Note shall be so surrendered for exchange or cancellation as provided in this Article Three or (ii) the principal amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or cancelled, or equal to the principal amount of such other Note to be so exchanged for a beneficial interest therein, as the case may be, by means of an appropriate adjustment made on the records of the Trustee, as Co-Registrar, whereupon the Trustee, in accordance with the Applicable Procedures, shall instruct the Depositary or its authorized representative to make a corresponding adjustment to its records. Upon any such surrender or adjustment of a Global Note, the Trustee shall, subject to Section 3.5(b) and as otherwise provided in this Article Three, authenticate and deliver any Notes issuable in exchange for such Global Note (or any portion thereof) to or upon the order of, and registered in such names as may be directed by, the Depositary or its authorized representative. Upon the request of the Trustee in connection with the occurrence of any of the events specified in the preceding paragraph, the Company shall promptly make available to the Trustee a reasonable supply of Notes that are not in the form of Global Notes. The Trustee shall be entitled to rely upon any order, direction or request of the Depositary or its authorized representative which is given or made pursuant to this Article Three if such order, direction or request is given or made in accordance with the Applicable Procedures.

(d)

Every Note authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Note or any portion thereof, whether pursuant to this Article Three, Section 9.5, Section 11.5(1) or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Note, unless such Note is registered in the name of a Person other than the Depositary for such Global Note or a nominee thereof.

(e)

The Depositary or its nominee, as registered owner of a Global Note, shall be the Holder of such Global Note for all purposes under this Indenture and the Notes, and owners of beneficial interests in a Global Note shall hold such interests pursuant to the Applicable Procedures. Accordingly, any such owner’s beneficial interest in a Global Note shall be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or its nominee or its Agent Members; provided, however, that, notwithstanding the foregoing, a beneficial owner of a Global Note shall have the right (i) to obtain evidence of its beneficial ownership interest in a Global Note in accordance with section 129 of the Argentine Capital Markets Law, from any securities clearing service or collective deposit system, including DTC, Euroclear, Clearstream and Luxembourg, as applicable, and (ii) with such evidence to pursue remedies against the Company and assert rights in a legal action brought in Argentina under Argentine law in respect of its beneficial ownership interest in such a Global Note (including the right to initiate summary proceedings (acción ejecutiva) in Argentina in the manner provided by the Argentine Negotiable Obligations Law with respect thereto), and for such purposes such beneficial owner shall be treated as the owner of that portion of the Global Note which represents its beneficial ownership interest therein.

3.6	Registration, Registration of Transfer and Exchange Generally; Certain Transfers and Exchanges; Securities Act Legends

(a)	Registration, Registration of Transfer and Exchange Generally

The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a place of payment (the “Place of Payment”) being herein sometimes collectively referred to as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers and exchanges of Notes. The Trustee is hereby appointed Co-Registrar and Banco Santander Argentina S.A. (at its principal office in Buenos Aires, Argentina) is hereby appointed as Registrar for the purpose of registering the Notes and transfers and exchanges of Notes as herein provided. The Note Register shall be in written form in the English language or in any other form capable of being converted into such form within a reasonable time. The Co-Registrar shall give prompt notice to the Registrar and the Registrar shall likewise give prompt notice to the Co-Registrar of any registration of ownership, exchange or transfer of Notes. As long as it is required by Argentine law or by the CNV, the Registrar shall keep a duplicate of the Note Register in the Spanish language in Argentina.

Exhibit 2.4.2 - 44

Upon surrender for registration of transfer of any Note of a series at an office or agency of the Company designated pursuant to Section 10.3 for such purpose, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of the same series, of any authorized denominations and of a like tenor and aggregate principal amount and bearing such restrictive legends as may be required by this Indenture.

At the option of the Holder, Notes may be exchanged for other Notes of the same series of any authorized denominations and of a like tenor and aggregate principal amount, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is entitled to receive.

All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes, surrendered upon such registration of transfer or exchange.

Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed, by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of Notes, but the Company or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Sections 3.4, 9.5 and 11.5(1) not involving any transfer.

If the Notes of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (i) to issue, register the transfer of or exchange any Note of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Notes selected for redemption under Section 11.3 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

(b)	Certain Transfers and Exchanges

Notwithstanding any other provision of this Indenture or the Notes, so long as Notes remain Outstanding, transfers and exchanges of Notes and beneficial interests in a Note of the kinds specified in this Section 3.6(b) shall be made only in accordance with this Section 3.6(b).

Neither the Trustee nor any Agent shall have any responsibility or liability for any actions taken or not taken by the Depositary.

(iii)

Registered Notes shall not bear a Securities Act Legend;

(iv)

in the event the Trustee has received a written opinion of U.S. counsel in a form satisfactory to the Trustee stating that the Notes are not “Restricted Securities” as defined by Rule 144(a)(3) under the Securities Act, a new Note which does not bear a Securities Act Legend may be issued in exchange for or in lieu of a Note (other than a Global Note) or any portion thereof which bears such a legend, and after such date and receipt of such opinion, the Trustee upon receipt of a Company Order shall authenticate and deliver such a new Note in exchange for or in lieu of such other Note as provided in this Article Three;

(vi)

notwithstanding the foregoing provisions of this Section 3.6(c), a Successor Note of a Note that does not bear a particular form of Securities Act Legend shall not bear such form of legend unless the Company has reasonable cause to believe that such Successor Note is a “Restricted Security” within the meaning of Rule 144(a)(3), in which case the Trustee, upon receipt of a Company Order, shall authenticate and deliver a new Note bearing a Restricted Notes Legend in exchange for such Successor Note as provided in this Article Three.

Exhibit 2.4.2 - 49

(d) All the provisions and undertakings set forth above concerning registration of ownership, exchange and transfer of the Notes shall be, in fact, exclusively fulfilled by CSC Delaware Trust Company acting as Co-Registrar, Principal Paying Agent and Transfer Agent. In the event that Banco Santander Argentina S.A. is required to carry out any of the obligations related to the registration of ownership, or exchange and transfer of Notes, as required by Argentine law and by the CNV, it can delegate such duties on any other entity acting in Argentina with legal capacity to carry them out in compliance with this Indenture and laws and regulations in force in Argentina. To do so, the Registrar, Paying Agent and Transfer Agent shall promptly notify the Company and the Co-Registrar about that circumstance, in order that the Company appoints the entity it deems appropriate to assume the Registrar’s obligations. Once the appointment is made, and such is accepted by the appointed entity, the Registrar shall not be liable for the breach of any of the obligations assumed by the delegate registrar according to this Indenture and shall be indemnified by the Company for and held harmless against, any and all losses, damages, liabilities, judgments, claims, causes of action, costs and expenses (including fees and disbursements of legal counsel) incurred directly or indirectly, without negligence or bad faith on their part, duly declared as such by a final resolution of a competent court, arising out of or in connection with the performance of the duties assumed by the delegate registrar under this Indenture.

3.7	Mutilated, Destroyed, Lost and Stolen Notes

If any mutilated Note is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Note of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be reasonably required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a protected purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Note, a new Note of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note.

Upon the issuance of any new Note under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Note of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Notes of that series duly issued hereunder.

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

3.8	Payment of Interest; Interest Rights Preserved

Except as otherwise provided as contemplated by Section 3.1 with respect to any series of Notes, interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date, as set forth in such Notes, for such interest.

Any interest on any Note of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

Exhibit 2.4.2 - 50

(1)

The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes of such series (or their respective Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than ten days prior to the date of the proposed payment and not less than ten days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Notes of such series in the manner set forth in Section 1.6, not less than ten days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes of such series (or their respective Predecessor Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

(2)

The Company may make payment of any Defaulted Interest on the Notes of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. The Trustee shall not at any time be under any duty or responsibility to any holder of Notes to determine the Defaulted Interest, or with respect to the nature, extent, or calculation of the amount of Defaulted Interest owed, or with respect to the method employed in such calculation of the Defaulted Interest.

Subject to the foregoing provisions of this Section, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

3.9	Persons Deemed Owners

Prior to due presentment of a Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of and any premium and (subject to Section 3.8) any interest on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

Exhibit 2.4.2 - 51

3.10	Cancellation

All Notes surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Notes previously authenticated hereunder which the Company has not issued and sold, and all Notes so delivered shall be promptly cancelled by the Trustee. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by this Indenture. The Trustee shall dispose of all cancelled Notes in accordance with customary practices.

The Company shall not make any payment to any Holder who has instituted proceedings directly against the Company under the Argentine Negotiable Obligations Law, without giving notice to the Trustee of the certificate numbers of the Notes in respect of which such payment is to be made, and the amount to be paid in respect of each such Note. Further, the Company shall not make any such payment without canceling or procuring the cancellation of such Notes or, in the case of partial payments not intended fully to discharge the Company’s obligations under such Notes, enfacing or procuring the enfacement of such Notes with the amount of such payment.

3.11	CUSIP Numbers

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

3.12	Payments and Paying Agents

(a)

The Company shall, by 10:00 AM (New York City time) at least one Business Day prior to each due date of the principal or premium of or interest on any Notes (including Additional Amounts), deposit with the Trustee, in its capacity as Principal Paying Agent, a sum sufficient to pay such principal, premium or interest (including Additional Amounts) so becoming due; provided that all payments of principal, interest, premium, if any, and Additional Amounts, if any, with respect to Notes represented by one or more Global Notes registered in the name of or held by or on behalf of DTC or its nominee will be made by wire transfer of immediately available funds to DTC.

(b)

Each of the Paying Agents hereby agrees (and whenever the Company shall appoint a Paying Agent with respect to the Notes other than those specified in Section 10.3, it will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree), subject to the provisions of this Section,

(i)	that it will hold all sums received by it as such agent for the payment of the principal of or interest on any Notes (whether such sums have been paid to it by or on behalf of the Company) in trust for the benefit of the Holders of such Notes or of the Trustee,

(ii)

that it will give the Trustee notice of any failure by the Company to make any payment of the principal of or interest on any Notes (including Additional Amounts) and any other payments to be made by or on behalf of the Company under this Indenture or such Notes when the same shall be due and payable, and

Exhibit 2.4.2 - 52

(iii)

that it will pay any such sums so held in trust by it to the Trustee upon the Trustee’s written request at any time during the continuance of the failure referred to in subclause (b)(ii) above.

The Company shall give, at its expense, notice of the appointment of any Paying Agents (other than those specified in the recitals to this Indenture) to the Holders as specified in Section 1.6, and to the CNV if required under Argentine Law.

The Trustee, in its capacity as the Principal Paying Agent, shall arrange with all the Paying Agents for the payment, from funds furnished by the Company to the Trustee pursuant to this Indenture, of the principal of and interest on the Notes (including Additional Amounts) and of the compensation of such Paying Agents for their services as such from funds furnished by the Company to the Trustee. The Trustee will not be required to make payments of principal and interest on the Notes (including Additional Amounts) to Holders unless it has received such funds.

If the Company shall act as its own paying agent with respect to any Notes, it will, on or before each due date of the principal of or interest on such Notes, set aside, segregate and hold in trust for the benefit of the Holders of such Notes a sum sufficient to pay such principal or interest (including Additional Amounts) so becoming due. The Company will promptly notify the Trustee in writing of any failure to take such action.

Anything in this Section to the contrary notwithstanding, the Company may at any time, for the purpose of obtaining a satisfaction and discharge with respect to any Notes hereunder, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust for such Notes by the Company or any Paying Agent hereunder, as required by this Section, such sums to be held by the Trustee upon the trusts herein contained.

3.13	Computation of Interest

Except as otherwise specified as contemplated by Section 3.1 for Notes of any series, interest (including additional interest or any other amount that may constitute interest) on the Notes of each series shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

4.	SATISFACTION AND DISCHARGE

4.1	Satisfaction and Discharge of Indenture

This Indenture shall upon Company Request cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Notes herein expressly provided for), and the Trustee, as to all Notes issued thereunder, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when

(1)

either

(A)

all Outstanding Notes (other than (i) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 3.7 and (ii) Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in the last paragraph of Section 10.4) have been delivered to the Trustee for cancellation; or

(B)

all such Notes not theretofore delivered to the Trustee for cancellation

(i)

have become due and payable, or

Exhibit 2.4.2 - 53

(ii)

will become due and payable at their Stated Maturity within one year, or

(iii)

are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company,

and the Company or any Restricted Subsidiary, in the case of (B)(i), (B)(ii) or (B)(iii) above, has deposited with the Trustee (or another entity designated by the Trustee for such purposes) funds in trust solely for the benefit of Holders in the form of cash in U.S. dollars, U.S. Government Obligations, or a combination thereof, in an amount sufficient (without reinvestment), to pay and discharge the entire indebtedness on such Notes not theretofore delivered to the Trustee for cancellation, for principal and any premium and interest to the date of such deposit (in the case of Notes which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be;

(2)

no Default or Event of Default has occurred and is continuing on the date of the deposit or will occur as a result of the deposit and the deposit will not result in a breach or violation of, or constitute a default under, any other material instrument to which the Company or any of its Restricted Subsidiaries are a party or by which the Company or any of its Restricted Subsidiaries are bound;

(3)	the Company or any Restricted Subsidiary has paid or caused to be paid all other sums payable hereunder by the Company or such Restricted Subsidiary; and

(4)	the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply any deposited money toward the payment of the Notes at maturity or the Redemption Date, as the case may be.

In addition, the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 6.7, the obligations of the Company to any Authenticating Agent under Section 6.14 and, if money shall have been deposited with the Trustee pursuant to subclause (1)(B) of this Section, the obligations of the Trustee under Section 4.2 and the last paragraph of Section 10.4 shall survive.

4.2	Application of Trust Money

Subject to the provisions of the last paragraph of Section 10.4, all money deposited with the Trustee pursuant to Section 4.1 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 Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and any premium and interest for whose payment such money has been deposited with the Trustee.

REMEDIES

5.1	Events of Default

Event of Default, wherever used herein with respect to the Notes of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body).

Exhibit 2.4.2 - 54

(1)	Non-payment. The Company fails to pay:

(a)	any principal of, or premium on, any of the Notes when due, or

(b)	Additional Amount or interest on, any of the Notes when due and such failure remains uncured for a period of 30 days; or

(2)

Breach of other obligations. The Company does not perform or comply with any one or more of the Company’s other obligations in the Notes or the Indenture, and such default or breach continues for a period of 60 consecutive days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding Notes a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or

(3)	Cross-acceleration. Either:

(a)

the Company or any Significant Subsidiary shall default (as principal or guarantor or other surety) in the payment of principal of any Indebtedness in the principal amount when due of at least US$75 million in the aggregate (or its equivalent in any other currency), such default shall have continued for more than any applicable period of grace and any time for payment of such amounts has not been expressly extended, and such failure to pay results in the acceleration of the final scheduled maturity thereof; or

(b)	Indebtedness of the Company or any Significant Subsidiary is accelerated by the holders thereof because of a default, and the aggregate principal amount of such accelerated Indebtedness exceeds US$75 million; or

(4)

Enforcement proceedings. With respect to the Company, any final and non-appealable judgment or order for the payment of money in excess of US$75 million or its equivalent in other currencies (to the extent not covered by insurance as acknowledged in writing by the insurer) is rendered against the Company and such judgment or order remains undischarged or unstayed for a period of 90 days after such judgment becomes final and non-appealable; or

(5)

Bankruptcy; insolvency; etc. (a) A court having jurisdiction shall enter a decree or order for the (x) relief in respect of the Company or any Significant Subsidiaries in an involuntary case under the ABL, or (y) appointment of an administrator, receiver, trustee or intervenor for the Company or any Significant Subsidiaries for all or substantially all of the Company’s or any of its Significant Subsidiaries’ Property and, in each case, such decree or order shall remain unstayed and in effect for a period of 60 consecutive days; (b) the Company or any of its Significant Subsidiaries (x) commences a voluntary case under the ABL including, without limitation, any out-of-court agreement (acuerdo preventivo extrajudicial) impairing the Notes, (y) consent to the appointment of or taking possession by an administrator, receiver, trustee or intervenor for the Company or any of its Significant Subsidiaries for all or substantially all of the Company’s or any of its Significant Subsidiaries’ Properties or (z) effect any general assignment for the benefit of creditors; or (c) a moratorium (estado de cesación de pagos) is declared in respect of any of the Company or any of its Significant Subsidiaries; or

(6)

Winding up. A resolution is passed or adopted by the Company’s Board of Directors or shareholders, or a ruling or judgment of a Governmental Authority having jurisdiction or a court of competent jurisdiction is made, that the Company be wound up or dissolved, other than pursuant to a merger, consolidation or other transaction otherwise permitted in accordance with the terms of Section 8.1 and, in the case of any such ruling or judgment, remains unstayed and in effect for a period of 60 consecutive days; or

Exhibit 2.4.2 - 55

(7)

Revocation of License. The License is permanently revoked by an Argentine Governmental Authority (other than by expiration of its term) and such revocation has a material adverse effect on the Company or its Subsidiaries taken as a whole;; provided, further, that a reissuance, extension or reauthorization of the License shall not constitute a revocation or suspension.

5.2	Acceleration of Maturity; Rescission and Annulment

If an Event of Default (other than an Event of Default specified in clause (5) or (6) of Section 5.1) occurs and is continuing with respect to Notes of a series at the time Outstanding, then the Holders of not less than 25% in principal amount of the Notes Outstanding of the series affected by such Event of Default may declare the principal amount of the Notes of such series (or, if any Notes of that series are Original Issue Discount Notes, such portion of the principal amount of such Notes as may be specified by the terms thereof) to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount of such Notes (or specified amount), together with accrued interest thereon and Additional Amounts, if any, shall become immediately due and payable. If an Event of Default occurs and is continuing under clause (5) and (6) of Section 5.1, then the principal amount of all Notes then Outstanding and all interest accrued thereon and Additional Amounts, if any, shall become immediately due and payable without any further action or notice by the Trustee or the Holders of the Notes. At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Notes of each series of Notes affected by such Event of Default, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

(1)	the Company has paid or deposited with the Trustee a sum sufficient to pay

(A)

all overdue interest on such series of Notes,

(B)

the principal of (and premium and Additional Amounts, if any, on) any series of Notes which have become due otherwise than by such declaration of acceleration and any 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 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

(2)	all Events of Default with respect to a series of Notes, other than the non-payment of the principal of a series of Notes, which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13.

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

5.3	Collection of Indebtedness and Suits for Enforcement by Trustee

The Company covenants that if:

Exhibit 2.4.2 - 56

(1)	default is made in the payment of any Additional Amount or interest on any Note when such interest becomes due and payable and such default continues for a period of 30 days after the date on which such payment was due and payable, or

(2)	default is made in the payment of the principal of (or premium, if any, on) any Note at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal (and any premium) and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium 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 an Event of Default with respect to Notes of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Notes of such series 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.

As provided in the Argentine Negotiable Obligations Law, any Holder may institute proceedings directly against the Company in accordance with the provisions of the Argentine Negotiable Obligations Law for the payment of past due principal, premium, or interest (including Additional Amounts), but from the date such proceedings are instituted, the Holder of such Notes shall cease to have any rights under the trust created by these presents, or to moneys held in trust hereunder (including moneys recovered by the Trustee prior to the institution of such proceedings). The Trustee shall be entitled to assume (and it is the intention of the Company and the Trustee that it shall assume) that no such proceedings have been instituted, unless the Trustee shall have received written notice to the contrary.

No security which has been the subject of proceedings under the Argentine Negotiable Obligations Law may be presented to a Paying Agent or Registrar and Co-Registrar for payment or replacement but in such circumstances the Company shall make separate arrangements for payment directly to the Holder of each such Note. If any Holder, having instituted proceedings directly against the Company in accordance with the provisions of the Argentine Negotiable Obligations Law, subsequently disposes of the Note forming the subject matter of such proceedings, the cessation of the rights under the trust created by these presents occurring upon the institution of such proceedings, shall inure in relation to the purchaser of such Note. Upon written notification by the Company of any such proceedings, the Trustee shall give notice to the Paying Agents and the Registrar and Co-Registrars of the serial numbers of those Notes forming the subject matter of such proceedings and the Paying Agents and Registrar and Co-Registrars shall make such serial numbers available to any Holder or potential Holder upon its request.

5.4	Trustee May File Proofs of Claim

In case of any judicial proceeding relative to the Company (or any other obligor upon the Notes), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act (as if it had applied to the Notes issued hereunder) in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; 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 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 it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.7.

Exhibit 2.4.2 - 57

No provision of this Indenture 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 thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.

5.5	Trustee May Enforce Claims Without Possession of Notes

All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes in respect of which such judgment has been recovered.

5.6	Application of Money Collected

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or any premium or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST:

To the payment of all amounts due the Trustee, Co-Registrar, Principal Paying Agent and Transfer Agent under this Indenture; and

SECOND:

To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Notes in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal and any premium and interest, respectively.

5.7	Limitation on Suits

Except as provided in Section 5.8 and the last two paragraphs of Section 5.3, no Holder of any Note of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(1)	such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Notes of that series;

(2)	the Holders of not less than 25% in principal amount of the Outstanding Notes of that series shall have made a written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(3)	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;

(4)	the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

Exhibit 2.4.2 - 58

(5)

no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of (i) in the case of a continuing Event of Default specified in clause (1) of Section 5.1, the Outstanding Notes of that series, (ii) in the case of a continuing Event of Default with respect to any series, other than the Event of Default specified in clause (1) of Section 5.1, the Outstanding Notes of all series affected by such Event of Default;

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders (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).

5.8	Unconditional Right of Holders to Receive Principal, Premium and Interest

Notwithstanding any other provision in this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 3.8) interest on such Note on the respective Stated Maturities expressed in such Note (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, whether in the manner established by Article 29 of the Argentine Negotiable Obligations Law, or otherwise, and such rights shall not be impaired without the consent of such Holder.

5.9	Restoration of Rights and Remedies

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture (including proceedings under Article 29 of the Argentine Negotiable Obligations Law) 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, the Company, 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.

5.10	Rights and Remedies Cumulative

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of Section 3.7, 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 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.

5.11	Delay or Omission Not Waiver

No delay or omission of the Trustee or of any Holder of any Notes 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.

Exhibit 2.4.2 - 59

5.12	Control by Holders

The Holders of a majority in principal amount of the Outstanding Notes of the affected series, voting together as a single class, present or represented and voting at a meeting of such Holders at which a quorum is present (or providing their written consent to the extent permitted under Argentine law and this Indenture) 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 of such affected series; provided that:

(1)	such direction shall not be in conflict with any rule of law or with this Indenture; and

(2)	the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

5.13	Waiver of Past Defaults

The Holders of not less than a majority in principal amount of the Outstanding Notes of all series affected by a past default hereunder with respect to such affected series may, on behalf of the Holders of all the Notes of such affected series, waive such past default and its consequences pursuant to a vote of the Holders of all such affected series, voting together as a single class, at a meeting of Holders at which a quorum is present (or by providing their written consent to the extent permitted under Argentine law and this Indenture), except a default:

(1)	in the payment of the principal of or any premium or interest on any Note of such affected series, or;

(2)	in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Note of such series 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 of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. Notwithstanding the foregoing, a declaration of acceleration may not be rescinded or annulled except as provided in Section 5.2.

5.14	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, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit (including legal fees and expenses), and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section 5.14 nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company or the Trustee.

5.15	Waiver of Usury, Stay or Extension Laws

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

Exhibit 2.4.2 - 60

5.16	Currency Indemnity

Any amount received or recovered in respect of the Notes in a currency other than the currency specified in the Notes (the “Specified Currency”) (whether as a result of, or of the enforcement of, a judgment or order of a court of any jurisdiction, in respect of the bankruptcy, liquidation or dissolution of the Company or otherwise) by any Holder of Notes in respect of any sum expressed to be due to it from the Company shall only constitute a discharge of the Company to the extent of the Specified Currency amount which the recipient is able to purchase 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 that Specified Currency amount is less than the Specified Currency amount expressed to be due to the recipient under any Note, the Company shall indemnify such recipient against any loss sustained by it as a result, and in any event, the Company shall indemnify the recipient against the cost of making any such purchase. For the purposes of this Section, it shall be sufficient for the Holder to certify in a manner reasonably satisfactory to Company (indicating the sources of information used) that it would have suffered a loss had an actual purchase of Specified Currency been made with the amount so received in that other currency on the date of receipt or recovery (or, if a purchase of Specified Currency on such date had not been practicable, on the first date on which it would have been practicable, it being required that the need for a change of date be certified in the manner mentioned above). These indemnities constitute a separate and independent obligation of the Company from its other obligations, shall give rise to a separate and independent cause of action, shall apply irrespective of any waiver granted by any Holder and shall continue in full force and effect despite any other judgment, order, claim or proof for a liquidated amount in respect of any sum due under any Note or any other judgment or order.

5.17	Prescription

All claims against the Company for the payment of principal in respect of the Notes (including Additional Amounts), shall be prescribed unless made within five (5) years of the due date for payment of such principal. Claims against the Company for the payment of interest (including Additional Amounts), shall be prescribed unless made within two (2) years of the due date for payment of such interest.

Claims filed in the courts of the State of New York against the Company for the payment of principal or interest in respect of the Notes (including Additional Amounts) will be prescribed unless made within six years of the corresponding due date for payment.

6.	THE TRUSTEE

6.1	Certain Duties and Responsibilities

(a)

If an Event of Default with respect to a particular series 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 their exercise, as a prudent person would exercise or use under the circumstances in the conduct of its own affairs.

(b)

Except during the continuance of an Event of Default with respect to a particular series:

(i)

the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need perform, and be liable for (as set forth herein), 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

Exhibit 2.4.2 - 61

(ii)

in the absence of bad faith or 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; provided that the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture stated herein (but need not verify any mathematical calculations).

(c)

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

(i)

this paragraph does not limit the effect of paragraph (b) of this Section 6.1;

(ii)

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

(d)

The Trustee shall not be deemed to have knowledge or notice of the occurrence of any default or event of default, unless a Responsible Officer of the Trustee shall have received written notice from the Issuer or a holder describing such default or event of default, and stating that such notice is a notice of default or event of default.

In case of the appointment hereunder of a successor Trustee with respect to all Notes, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

In case of the appointment hereunder of a successor Trustee with respect to the Notes of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Notes of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Notes of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Notes, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Notes of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Notes of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Notes of that or those series to which the appointment of such successor Trustee relates.

Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be.

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes.

Exhibit 2.4.2 - 67

6.13	Preferential Collection of Claims Against Company

If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor).

6.14	Appointment of Authenticating Agent

The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Notes which shall be authorized to act on behalf of the Trustee to authenticate Notes of such series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.7, and Notes so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Notes by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50.0 million and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment in the manner provided in Section 1.6 to all Holders of Notes of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section.

If an appointment with respect to one or more series is made pursuant to this Section, the Notes of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:

With the consent of Holders of not less than a majority in principal amount of the Outstanding Notes of all series affected by such supplemental indenture, provided pursuant to a vote of the Holders of such affected series, voting together as a single class, at a meeting of Holders at which a quorum is present (or by providing their written consent to the extent permitted under Argentine law and this Indenture), the Company, when authorized by a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of Notes of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Note affected thereby,

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Notes, or which modifies the rights of the Holders of Notes of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Notes of any other series.

It shall not be necessary for any meeting of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such meeting shall approve the substance thereof.

9.3	Execution of Supplemental Indentures

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall receive, in addition to the documents required by Section 1.2, and (subject to Section 6.1) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture and that such supplemental indenture is the legal, valid and binding obligation of the Company. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.

Exhibit 2.4.2 - 74

Promptly after the execution by the Company and the Trustee of any supplement or amendment to the Indenture or the Notes, the Company will give notice thereof to the Holders of the Notes as provided under Section 1.6 and, if applicable, to the CNV, setting forth in general terms the substance of such supplement or amendment. If the Company fails to give such notice to the Holders of the Notes within 15 days after the execution of such supplement or amendment to the Indenture, the Trustee will, upon request, give notice to the Holders at the expense of the Company. Any failure by the Company or the Trustee to give such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such supplement or amendment to the Indenture or the Notes, as the case may be.

9.4	Effect of Supplemental Indentures

Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

9.5	Reference in Notes to Supplemental Indentures

Notes of any series authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall, if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Notes of any series so modified as to conform, in the opinion of the Company, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Notes of such series.

9.6	Meetings of Holders; Modification and Waiver

(a)

The Trustee or the Board of Directors of the Company shall, upon the request of the Holders of at least five percent in aggregate principal amount of the Notes of all series at the time Outstanding or of the Notes of any series at the time Outstanding, or the Company or the Trustee, at its discretion, may, call a meeting of the Holders of such Notes at any time and from time to time, to make, give or take any request, demand, authorization, direction, notice, consent, waiver or other action provided by the Notes or the relevant series of Notes to be made, given or taken by the Holders of such Notes. With respect to all matters not contemplated in this Indenture, meetings of Holders shall be convened and held in accordance with the provisions of the Argentine Negotiable Obligations Law and the Argentine Corporations Law.

The meetings may be held virtually (in such case, and for the avoidance of doubt, it shall not be required to be held simultaneously in the City of Buenos Aires and New York City), to the extent permitted by applicable law and shall be subject to the requirements set forth therein. In any case, meetings shall be held at such time and at such place as the Company or the Trustee shall determine. Any resolution passed at a meeting shall be binding on all Holders of Notes or of the relevant series of Notes, as the case may be (whether present or not at such meeting). If a meeting is being held pursuant to a request of Holders, the agenda for the meeting shall be as determined in the request and such meeting shall be convened within 40 days from the date such request is received by the Trustee or the Company, as the case may be.

Exhibit 2.4.2 - 75

(b)

Notice of any meeting of Holders (which shall include the date, place and time of the meeting, the agenda therefor and the requirements for attendance) shall be given, at the Company’s expense, not less than ten nor more than 30 days prior to the date fixed for the meeting and shall be published by or on behalf for five Business Days in Argentina in the Official Gazette of Argentina (Boletín Oficial), in a newspaper of wide circulation in Argentina and in the Bulletin of the BCBA and the Electronic Bulletin of the A3 Mercados (as long as the Notes are listed and traded on BYMA and A3 Mercados, accordingly) or such other informative systems of the markets in which the Notes are listed, as applicable.( Meetings of the Holders may be simultaneously convened for two dates, in case the initial meeting were to be adjourned for lack of quorum. However, for meetings that include in the agenda items requiring the consent of each Holder affected thereby, notice of a new meeting resulting from adjournment of the initial meeting for lack of quorum will be given not less than eight days prior to the date fixed for such new meeting and will be published for three Business Days in the Official Gazette of Argentina, a newspaper of wide circulation in Argentina and in the Bulletin of the BCBA and the Electronic Bulletin of the A3 Mercados (as long as the Notes are listed and traded on ▇▇▇▇ and A3 Mercados) or such other informative systems of the markets in which the Notes are listed, as applicable.

(c)

To be entitled to vote at a meeting of Holders, a person shall be (i) a Holder of one or more Notes as of the relevant record date or (ii) a person appointed by an instrument in writing as proxy by such a Holder of one or more Notes.

(d)

The quorum at any meeting to adopt a resolution with respect to the Notes of any series will be Persons who are Holders of or who represent at least 60% of theaggregate principal amount of the Notes of the affected series at the time Outstanding (excluding any Notes held by the Company or an affiliate of the Company). No business shall be transacted, unless a quorum is present when the meeting is called to order. In the absence of a quorum within 30 minutes of the time appointed for any such meeting, the meeting shall be adjourned for a period of one hour and the quorum for the reconvened meeting shall be persons holding or representing at least a majority in aggregate principal amount of Notes at the time Outstanding (other tan Notes held by the Company or an affiliate of the Company); provided, however, that the quorum for any meeting relating to the matters specified in Sections 9.2(1) through 9.2(14) will be persons representing 100% in aggregate principal amount of the Outstanding Notes. Timing for crediting absence and adjourning meetings for lack of quorum will be established pursuant to applicable law.

(e)

Any instrument given by or on behalf of any Holder in connection with any consent to any such modification, amendment or waiver will be irrevocable once given and will be conclusive and binding on all subsequent Holders of such Note. Any modifications, amendments or waivers to the Indenture or to the Notes will be conclusive and binding upon all Holders of such Notes whether or not they have given such consent or were present at any meeting, and on all Notes. The Holder of a Note may, at any meeting of Holders of Notes at which such ▇▇▇▇▇▇ is entitled to vote, cast one vote for each U.S. Dollar in principal amount of the Notes held by such Holder in which the Notes are denominated. Decisions at a meeting of Holders shall be made by the affirmative vote of a majority in aggregate principal amount of the Notes of any affected series at the time Outstanding, voting together as a single class, present or represented at a meeting of such holders at which a quorum is present; provided, however, that the unanimous consent or the unanimous affirmative vote of the Holders shall be required to adopt a valid decision on any of the matters listed under clauses 9.2(1) through 9.2(14) above.

Exhibit 2.4.2 - 76

(f)

The Company will designate the record date for determining the Holders of Notes entitled to vote at any meeting and will provide notice to such Holders in the manner set forth in the Indenture. The Holder of a Note may, at any meeting of Holders of Notes at which such ▇▇▇▇▇▇ is entitled to vote, cast one vote for each U.S. Dollar in principal amount of the Notes held by such Holder in which the Notes are denominated. Decisions at a meeting of Holders shall be made by the affirmative vote of a majority in aggregate principal amount of the Notes of any affected series at the time Outstanding, voting together as a single class, present or represented at a meeting of such holders at which a quorum is present; provided, however, that the unanimous consent or the unanimous affirmative vote of the Holders shall be required to adopt a valid decision on any of the matters listed under clauses 9.2(1) through 9.2(14) above.

9.7	Actions to be Taken Without a Meeting

The Holders of the Notes may act, in lieu of a meeting, through written consent or may consent by means of any other procedure (including through the DTC Omnibus Proxy and other internationally recognized clearinghouse consent solicitation systems) that the Company or the Trustee may implement in accordance herewith and Argentine law. Pursuant to the Argentine Negotiable Obligations Law, approval of any amendment, supplement or waiver by the Holders requires the consent of such Holders to be obtained pursuant to any other reliable means that ensures Holders of Notes prior access to information and allows them to vote, in accordance with Section 14 of the Argentine Negotiable Obligations Law (as amended by Section 151 of the Argentine Productive Financing Law No. 27,440) and any other applicable regulation.

10.

COVENANTS

10.1	Payment of Principal, Premium and Interest

The Company covenants and agrees for the benefit of each series of Notes that it will duly and punctually pay the principal of, and any premium and interest on, the Notes of that series in accordance with the terms of the Notes and this Indenture.

10.2	Payment of Additional Amounts

All payments made by the Company or on its behalf or a successor thereto (each, a “Payor”) under, or with respect to, the Notes will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, assessment or other governmental charge of whatever nature (including penalties, interest and other liabilities related thereto) (collectively, “Taxes”), unless the withholding or deduction of such Taxes is then required by law or the interpretation or administration thereof.

If, at any time, any deduction or withholding for, or on account of, any Taxes imposed, established, levied, collected or assessed by or on behalf of (1) Argentina or any political subdivision or Governmental Authority thereof or therein having the power to tax, (2) any jurisdiction from or through which payment on the Notes is made by or on behalf of the Payor, or any political subdivision or Governmental Authority thereof or therein having the power to tax, (3) any other jurisdiction in which a Payor is organized, engaged in business or otherwise resident for tax purposes, or any political subdivision or Governmental Authority thereof or therein having the power to tax or (4) following the consummation of any transaction described under Section 8.1, the jurisdiction under the laws of which the Company or the surviving entity thereof, as the case may be, is organized (or, in each case, any political subdivision or authority thereof or therein) having power to tax (each of clause (1), (2), (3) and (4), a “Relevant Taxing Jurisdiction”) will be required from any payments made with respect to the Notes, including payments of principal, premium, if any, redemption price or interest, the Payor will pay (together with such payments) such additional amounts (the “Additional Amounts”) as may be necessary in order that the net amounts received by the Holders of the Notes after such withholding or deduction (including any such deduction or withholding from such Additional Amounts) in respect of such Taxes shall equal the respective amounts which would have been receivable by each Holder in respect of such payments in the absence of such withholding or deduction; provided that no such Additional Amounts will be payable with respect to:

Exhibit 2.4.2 - 77

(1)

any Taxes that would not have been so imposed, deducted or withheld but for the existence of any present or former connection between the relevant Holder or beneficial owner of a Note (or between a fiduciary, settlor, beneficiary, member, partner or shareholder of, the relevant Holder or beneficial owner, if the relevant Holder or beneficial owner is an estate, nominee, trust, limited liability company, partnership or corporation) and the Relevant Taxing Jurisdiction (including being a citizen or resident or national or domiciliary of, or carrying on a business or maintaining a permanent establishment that is the holder of the Notes in the Relevant Taxing Jurisdiction), other than the mere ownership, holding, purchase or disposition of such Note or the receipt of such payment in respect thereof, or the exercise or enforcement of any rights under the Notes or the Indenture;

(2)

any Taxes which are imposed, payable or due because definitive Notes are presented for payment (where presentation is required) more than 30 days after the later of (a) the date such payment was due and (b) if the full amount payable has not been received by the Trustee on or prior to such due date, the date on which, the full amount having been so received, notice to that effect will have been given to the Holders by the Trustee; except for Additional Amounts with respect to Taxes that would have been imposed had the Holder presented the Note for payment during such 30-day period;

(3)

any Taxes that are imposed or withheld by reason of the failure of the Holder or beneficial owner of a Note to comply, at the Company’s written request, with any certification, identification, information, documentation or other reporting requirements if (a) such compliance is required or imposed by a statute, treaty or regulation or administrative practice of the Relevant Taxing Jurisdiction as a precondition to exemption from, or reduction in the rate of deduction or withholding of, such Taxes, and (b) the Company has given the Holder or the beneficial owner at least 30 days’ notice that the Holder or beneficial owner will be required to so comply;

(4)	any Note presented for payment (where presentation is required) at an office of a paying agent in Argentina (provided that the Notes can also be presented at an office of a paying agent outside of Argentina without any such withholding or deduction);

(5)	any Taxes payable otherwise than by withholding or deduction from payments on or with respect to the Notes;

(6)

any Taxes imposed pursuant to Sections 1471-1474 of the U.S. Internal Revenue Code (or any amended or successor version that is substantively comparable and not materially more onerous to comply with), the U.S. Treasury regulations thereunder and any other official guidance thereunder (“FATCA”), any intergovernmental agreement entered into with respect to FATCA, or any law, regulation or other official guidance enacted in any jurisdiction implementing, or relating to, FATCA, or any such intergovernmental agreement;

(9)	any combination of (1), (2), (3), (4), (5), (6), (7) or (8) above.

No Additional Amounts shall be paid with respect to any payment on a Note to a Holder that is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent that a beneficiary or settler with respect to such fiduciary or a member of such partnership or beneficial owner would not have been entitled to receive the Additional Amounts had such beneficiary, settler, member or beneficial owner been the direct Holder.

References herein and in the Notes to the payment of principal (and premium, if any), Redemption Price, interest or any other amounts payable with respect to any Notes shall include the payment of Additional Amounts if Additional Amounts are, were or would be payable in respect thereof, even where Additional Amounts are not specifically mentioned.

The Company shall pay any stamp, issue, registration, documentary or other similar taxes and duties, including interest and penalties, payable in Argentina, Luxembourg, Belgium, the United Kingdom or the United States or any authority of or in the foregoing in respect of the creation, issue and offering of the Notes.

10.3	Maintenance of Office or Agency

The Company shall maintain in each Place of Payment for any series of Notes an office or agency where Notes of that series may be presented or surrendered for payment, where Notes of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Notes of that series and this Indenture may be served. The Company will 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 Company 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, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

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

With respect to any Global Note, and except as otherwise may be specified for such Global Note as contemplated by Section 3.1, the Corporate Trust Office of the Trustee shall be the Place of Payment where such Global Note may be presented or surrendered for payment or for registration of transfer or exchange, or where successor Notes may be delivered in exchange therefor; provided, however, that any such payment, presentation, surrender or delivery effected pursuant to the Applicable Procedures of the Depositary for such Global Note shall be deemed to have been effected at the Place of Payment for such Global Note in accordance with the provisions of this Indenture.

The Company hereby appoints the Trustee as Principal Paying Agent under this Indenture, and the Trustee hereby accepts this appointment.

Exhibit 2.4.2 - 79

10.4	Money for Notes Payments to Be Held in Trust

If the Company shall at any time act as its own Paying Agent with respect to any series of Notes, it will, on or before each due date of the principal of or any premium or interest on any of the Notes of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.

Whenever the Company shall have one or more Paying Agents for any series of Notes, it will, prior to each due date of the principal of or any premium or interest on any Notes of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

The Company will cause each Paying Agent for any series of Notes other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) hold all sums held by it for the payment of the principal of (and premium, if any) or interest on the Notes of that series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and give the Trustee notice of any default by the Company (or any other obligor upon the Notes of that series) in the making of any payment of principal (and premium, if any) or interest on the Notes of that series; and (2) during the continuance of any default by the Company (or any other obligor upon the Notes of that series) in the making of any payment in respect of the Notes of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Notes of that series.

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or any premium or interest on any Note of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease.

10.5	Pari Passu

The Company shall ensure at all times that its obligations under the Notes of each series and this Indenture constitute unconditional general obligations of the Company ranking at least pari passu with all other unsecured and unsubordinated Indebtedness of the Company (other than Indebtedness ranking senior thereto by statute or operation of law).

10.6	Reporting; Statements by Officers as to Default

The Company shall file with the Trustee such information, documents or reports as are required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act within five Business Days after the same is actually filed with the SEC. If the Company at any time is not required to file information, documents or reports pursuant to Section 13 or Section 15(d) of the Exchange Act, the Company shall file with the Trustee and the SEC, in accordance with rules and regulations prescribed from time to time by the SEC, such of the supplementary and periodic information, documents and reports that may be required pursuant to Section 13 of the Exchange Act in respect of a security listed and registered on a national securities exchange. The filing of any information, document or report with the SEC shall satisfy the Company’s obligation to deliver such information, document or report to the Trustee; provided, however, that the Trustee shall have no responsibility whatsoever to determine if such filing has occurred.

In addition, the Company shall furnish to the Trustee: (i) within 120 days after the end of each fiscal year, a brief certificate from the principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of the Company’s compliance with all conditions and covenants under this Indenture (compliance, for such purpose, to be determined without regard to any period of grace or requirement of notice provided hereunder); (ii) upon any officer of the Company becoming aware of the existence of an Event of Default, a certificate of such officer, setting forth the details thereof and the action that the Company is taking or proposes to take with respect thereto; and (iii) written notification of any amendment to the License that has a material adverse effect over the Company or its subsidiaries taken as a whole, or of any termination or revocation to the License, in each case, within ten days of any such amendment, termination or revocation; provided that the filing of any information, document or report with the SEC shall satisfy the Company’s obligation to deliver such written notification in connection with any such amendment to, termination or revocation of the License.

The Trustee shall have no obligation to determine if the Company is required to file any report or other information pursuant to this provision, nor be responsible or liable for determining or monitoring whether or not the Company has otherwise delivered any report or other information in accordance with the requirements specified in the foregoing paragraph.

10.7

Existence

The Company shall (i) maintain in effect its corporate existence except as otherwise permitted under Section 8 and (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; provided, however, that this Section 10.7 shall not require the Company to maintain any such right, privilege, title to property or franchise if the Board of Directors of the Company shall determine that: (a) the maintenance or preservation thereof is no longer desirable in the conduct of the business of the Company and (b) the loss thereof is not, and will not be, adverse in any material respect to the Holders.

10.8	Further Assurances

The Company shall, at its own cost and expense, execute and deliver to the Trustee all such documents, instruments and agreements and do or cause to be done all such other acts and things as may be reasonably required, in the opinion of the Trustee, to enable the Trustee to exercise and enforce its rights under this Indenture and under the documents, instruments and agreements required under this Indenture and to carry out the intent of this Indenture.

10.9	Limitation on Transactions with Affiliates

The Company shall not, and shall not permit any Restricted Subsidiary to, enter into any transaction, including, without limitation, any purchase, sale, lease or exchange of property, or the rendering of any service, with any Affiliate of the Company (each, an “Affiliate Transaction”) unless such transaction is on terms that are not materially less favorable to the Company or any Restricted Subsidiary, as the case may be, than the Company or such Restricted Subsidiary would obtain in a comparable arm’s-length transaction with a Person who is not its Affiliate or an Affiliate of such Restricted Subsidiary; provided, however, that this Section 10.9 shall not restrict:

(6)

loans and advances to employees of the Company (including for the avoidance of doubt any successor) or any Restricted Subsidiary in the ordinary course of business in an aggregate outstanding principal amount not exceeding the greater of (x) US$5 million (or its equivalent in any other currency) and (y) 0.2% of Consolidated Total Assets;

(3) For purposes of determining compliance with, and the outstanding principal amount of, any particular Indebtedness Incurred pursuant to and in compliance with this Section 10.10:

(a)

the outstanding principal amount of any item of Indebtedness will be counted only once;

(b)

in the event that an item of Indebtedness meets the criteria of clause (1) or (2) above or more than one of the categories of Permitted Indebtedness described in subclauses (a) through (w) of clause (2) above, the Company may, in their sole discretion, divide and classify (or at any time reclassify) such item of Indebtedness in any manner that complies with this Section 10.10;

(c)

Indebtedness permitted by this Section 10.10 need not be permitted solely by reference to one provision permitting such Indebtedness, but may be permitted in part by such provision and in part by one or more other provisions of this Section 10.10 permitting such Indebtedness; and

Exhibit 2.4.2 - 86

(d)

the amount of any Indebtedness outstanding as of any date will be (i) the accreted value thereof in the case of any Indebtedness issued with original issue discount or the aggregate principal amount outstanding in the case of Indebtedness issued with interest payable in kind and (ii) the principal amount or liquidation preference thereof, together with any interest thereon that is more than 30 days past due, in the case of any other Indebtedness.

(4) Notwithstanding the foregoing, the Company may not Incur any Indebtedness pursuant to clause (2) above if the proceeds thereof are used, directly or indirectly, to Refinance any Subordinated Indebtedness or Deferred Interest Subordinated Indebtedness, 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 Indebtedness or Deferred Interest Subordinated Indebtedness, as applicable.

(5) For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. Dollar Equivalent principal amount of Indebtedness denominated in a non-U.S. currency will be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred; provided that, if such Indebtedness is Incurred to refinance other Indebtedness denominated in a non-U.S. currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction will be deemed not to have been exceeded so long as the principal amount of such Refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 10.10, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may Incur pursuant to this Section 10.10 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 Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, will be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of Incurrence of such Refinancing Indebtedness.

10.11

The amount of any Restricted Payments not in cash will be the Fair Market Value on the date of such Restricted Payment of the property, assets or securities proposed to be paid, transferred or issued by the Company or the relevant Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment.

10.12

Limitation on Asset Sales

The Company shall not, and shall not permit any Restricted Subsidiary to, make any Asset Sale unless:

(a)

the Company or such Restricted Subsidiary receives consideration (including by way of relief from, or by any other Person assuming sole responsibility for, any liabilities, contingent or otherwise) at the time of such Asset Sale at least equal to the Fair Market Value of the shares and/or assets subject to such Asset Sale; or

The Company or such Restricted Subsidiary, as the case may be, may apply the Net Cash Proceeds of any Asset Sale within 365 days after such Asset Sale to:

(a)

repay any of the Company’s or such Restricted Subsidiary’s Indebtedness that is pari passu with the Notes (whether through optional or mandatory prepayments or redemptions, or tender offers or open market or other privately negotiated purchases, so long as such repaid Indebtedness is immediately extinguished); provided that in connection with any such repayment of pari passu Indebtedness the Company offers to redeem a pro rata portion of the Notes based on the relative Outstanding principal amount of the Notes and such other Indebtedness, or

(b)	make capital expenditures in a Related Business, or

Exhibit 2.4.2 - 89

(c)

reinvest in or purchase Additional Assets (including by means of an investment in or purchase of Additional Assets by any Restricted Subsidiary with cash in an amount equal to the amount of Net Available Cash or Capital Stock to be used by the Company or any Restricted Subsidiary in a Related Business), or

(d)	any combination of (a), (b) or (c) above;

provided that application of (x) the Net Cash Proceeds from the sale of assets consisting of an Investment in an Unrestricted Subsidiary towards an Investment in another Unrestricted Subsidiary or (y) the Net Cash Proceeds from the sale of assets consisting of an Investment in a Person that is not a Subsidiary towards an Investment in another Person that is not a Subsidiary shall be deemed to satisfy the application requirements of this paragraph.

To the extent all or a portion of the Net Cash Proceeds of any Asset Sale are not applied within the 365 days of the Asset Sale as described in clauses (a) through (d) of the immediately preceding paragraph, the Company shall make an offer to purchase Notes (the “Asset Sale Offer”), at a purchase price equal to 100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest thereon to the date of purchase (the “Asset Sale Offer Amount”). The Company shall purchase pursuant to an Asset Sale Offer from all tendering Holders on a pro rata basis, and, at the Company’s option, on a pro rata basis with the Holders of any other Indebtedness with similar provisions requiring the Company to offer to purchase the other Indebtedness with the proceeds of Asset Sales, that principal amount (or accreted value in the case of Indebtedness issued with original issue discount) of Notes and the other Indebtedness to be purchased equal to such unapplied Net Cash Proceeds. The Company may satisfy its obligations under this Section 10.12 with respect to the Net Cash Proceeds of an Asset Sale by making an Asset Sale Offer prior to the expiration of the relevant 365-day period.

The purchase of Notes pursuant to an Asset Sale Offer shall occur not less than 20 Business Days following the date thereof, or any longer period as may be required by law, nor more than 45 days following the 365th day following the Asset Sale. The Company may, however, defer an Asset Sale Offer until there is an aggregate amount of unapplied Net Cash Proceeds from one or more Asset Sales equal to or in excess of US$50 million. At that time, the entire amount of unapplied Net Cash Proceeds, and not just the amount in excess of US$50 million, shall be applied as required pursuant to this Section 10.12. Pending application in accordance with this Section 10.12, Net Cash Proceeds may be applied to temporarily reduce revolving credit borrowings or invested in Cash and Cash Equivalents or Temporary Cash Investments. Each notice of an Asset Sale Offer shall be mailed first class, postage prepaid, to the record holders as shown on the register of Holders within 20 days following such 365th day, with a copy to the Trustee, offering to purchase the Notes as described above. Each notice of an Asset Sale Offer shall state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date the notice is mailed, other than as may be required by law (the “Asset Sale Offer Payment Date”). Upon receiving notice of an Asset Sale Offer, Holders may elect to tender their Notes in whole or in part in amounts of US$1,000 or in integral multiples of US$1,000 in excess thereof in exchange for cash.

On the Asset Sale Offer Payment Date, the Company shall, to the extent lawful:

(a)

accept for payment all Notes or portions thereof properly tendered pursuant to the Asset Sale Offer;

(b)

deposit with the Paying Agent funds in an amount equal to the Asset Sale Offer Amount in respect of all Notes or portions thereof so tendered; and

Exhibit 2.4.2 - 90

(c)

deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company.

To the extent Holders and holders of other Indebtedness, if any, that are the subject of an Asset Sale Offer properly tender and do not withdraw Notes or the other Indebtedness in an aggregate amount exceeding the amount of unapplied Net Cash Proceeds, the Company shall purchase the Notes and the other Indebtedness on a pro rata basis (based on amounts tendered). If only a portion of a Note is purchased pursuant to an Asset Sale Offer, a new Note in a principal amount equal to the portion thereof not purchased shall be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note shall be made, as appropriate). Notes (or portions thereof) purchased pursuant to an Asset Sale Offer shall be cancelled and not reissued.

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws in connection with the purchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 10.12, the Company shall comply with such laws and regulations and shall not be deemed to have breached its obligations under this Section 10.12 by doing so.

Following the application of such unapplied Net Cash Proceeds to the purchase of Notes or other Indebtedness, the amount of Net Available Cash shall be reset at zero and the Company shall be entitled to use any remaining proceeds for any corporate purposes to the extent not prohibited under this Indenture.

10.13

Limitation on Liens

The Company shall not, and shall not permit any Restricted Subsidiary to, create or permit to subsist any mortgage, charge, pledge, lien or other form of encumbrance or security interest (“Lien”) upon the whole or any part of its or, as the case may be, any such Restricted Subsidiary’s undertaking, assets or revenues present or future to secure any Indebtedness unless, at the same time or prior thereto, the Company’s obligations under the Notes and this Indenture (x) are secured equally and ratably therewith, or prior thereto, or (y) have the benefit of such other Lien as shall be approved by a meeting of Holders.

(x)	leases or subleases granted to others, easements, rights-of-way, restrictions and other similar charges or encumbrances, in each case incidental to, and not interfering with, the ordinary conduct of the Company’s business or the business of any of its Restricted Subsidiaries;

(xi)

(xii)

Liens on assets securing Attributable Debt under any Sale and Lease-Back Transaction permitted to be Incurred or assumed in accordance with Section 10.14; provided that any such Lien does not encumber any property other than the assets (including revenues therefrom or property incidental thereto) that are the subject of the applicable Sale and Lease-Back Transaction;

10.15

Limitation on Designation of Unrestricted Subsidiaries

Waiver of Certain Covenants

Except as otherwise specified as contemplated by Section 3.1 for Notes of such series, the Company may, with respect to the Notes of one or more series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to Section 3.1(18), 9.1(2) or 9.1(6) for the benefit of the Holders of such series or in any of Sections 10.5 through 10.17, inclusive, if, before the time for such compliance, the Holders of at least a majority in principal amount of the Outstanding Notes of all series with respect to which the Company seeks to waive compliance with such covenant, provided pursuant to a vote of the Holders of such affected series, voting together as a single class, present or represented and voting at a meeting of Holders of Notes of such series at which a quorum is present (or by providing their written consent to the extent permitted under Argentine law and this Indenture) either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

10.17

Release of Covenants

If on any date following the Issue Date:

(i)	with respect to any series of Notes issued under this Indenture, such series of Notes has been assigned an Investment Grade Rating by any two Nationally Recognized Statistical Rating Organizations; and

(ii)	no Default or Event of Default shall have occurred and be continuing,

then, beginning on that date and subject to the provisions of the following paragraph, the covenants set forth in Section 10.9, Section 10.10, Section 10.11, Section 10.12, Section 10.14 and Section 10.15 (collectively, the “Suspended Covenants”) will automatically, without any notice of any kind, be suspended with respect to such series of Notes and the Company and its Restricted Subsidiaries shall have no obligation or liability whatsoever with respect to such covenants.

If, during any period in which the Suspended Covenants are suspended with respect to a series of Notes, such series of Notes ceases to have an Investment Grade Rating from at least two Nationally Recognized Statistical Rating Organizations, the Suspended Covenants shall thereafter be reinstated and be applicable pursuant to their terms (including in connection with performing any calculation or assessment to determine compliance with the terms of this Indenture), unless and until such series of Notes subsequently attains an Investment Grade Rating by at least two Nationally Recognized Statistical Rating Organizations (in which event the Suspended Covenants will again be suspended with respect to such series for such time that such series of Notes maintains an Investment Grade Rating by at least two Nationally Recognized Statistical Rating Organizations); provided, however, that no Default, Event of Default or breach or violation of any kind will be deemed to exist under this Indenture or a series of Notes with respect to the Suspended Covenants (whether during the period when the Suspended Covenants were suspended or thereafter) based on, and neither the Company nor any of its Restricted Subsidiaries will bear any liability (whether during the period when the Suspended Covenants were suspended or thereafter) for, any actions taken or events occurring after a series of Notes attains an Investment Grade Rating by at least two Nationally Recognized Statistical Rating Organizations and before any reinstatement of the Suspended Covenants as provided above, or any actions taken at any time (whether during the period when the Suspended Covenants were suspended or thereafter) pursuant to any legal or contractual obligation arising prior to the reinstatement, regardless of whether those actions or events would have been permitted if the applicable Suspended Covenant had remained in effect during such period; provided, further, that (1) any Subsidiaries designated as Unrestricted Subsidiaries during the period on which the covenants were suspended shall automatically become Restricted Subsidiaries on the reversion date (subject to the Company’s right to redesignate them as Unrestricted Subsidiaries pursuant to Section 10.15), and (2) all Indebtedness Incurred, or Disqualified Capital Stock or Preferred Stock issued, during the Suspension Period will be classified to have been Incurred or issued pursuant to subclause (2)(b) of Section 10.10.

Exhibit 2.4.2 - 96

10.18

Financial Calculations

Any Applicable Metric to be determined in connection with an Applicable Transaction may, at the Company’s option, be determined as at the Applicable Transaction Date.

If compliance with an Applicable Metric is established in accordance with paragraph directly above, such Applicable Metric shall be deemed to have been complied with (or satisfied) for all purposes; provided that:

(i)

the Company may elect, in its sole discretion, to calculate or recalculate any Applicable Metric on the basis of a more recent Applicable Transaction Date, in which case, such date of redetermination shall thereafter be deemed to be the relevant Applicable Transaction Date for purposes of such Applicable Metrics; and

(ii)	save as contemplated in clause (1) above, compliance with any Applicable Metric shall not be determined or tested at any time after the relevant Applicable Transaction Date for such transaction and any actions or transactions related thereto.

For the avoidance of doubt, if any Applicable Metric for which compliance was determined or tested as of an Applicable Transaction Date would at any time after the Applicable Transaction Date have been exceeded or otherwise failed to have been complied with as a result of fluctuations in such Applicable Metric (or any other Applicable Metric), such Applicable Metric will not be deemed to have been exceeded or failed to have been complied with as a result of such fluctuations.

The Company will be responsible for making all calculations called for under this Indenture and the Notes, including but not limited to determination of redemption price, premium, if any, and any additional amounts or other amounts payable on the Notes. The Company shall make all such calculations in good faith and, absent manifest error, its calculations will be final and binding on Holders. The Issuer will provide a schedule of its calculations to the Trustee, and the Trustee is entitled to rely conclusively upon the accuracy of such calculations without independent verification. The Company shall deliver a copy of such schedule to any Holder upon the written request of such Holder.

11.	REDEMPTION AND REPURCHASE OF NOTES

11.1	Applicability of Article

Notes of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 3.1 for such Notes) in accordance with this Article.

Exhibit 2.4.2 - 97

11.2	Redemption for Tax Reasons

The Company may redeem the Notes in whole, but not in part, at any time upon giving not less than ten nor more than 60 days’ notice to the Holders and, if applicable, to the CNV at a redemption price equal to 100% of the principal amount of the Outstanding Notes, together with Additional Amounts, if any, and accrued and unpaid interest to, but excluding, the date of redemption, if, as a result of (1) any amendment to, or change in, the laws (or any rules, regulations or rulings issued thereunder) or treaties of a Relevant Taxing Jurisdiction, or (2) any amendment to, or change in, application, administration or official interpretation of such laws, rules, regulations, rulings or treaties (including, without limitation, the holding of a court of competent jurisdiction or a change in published administrative practices), which amendment or change becomes effective on or after the Issue Date (or, if a Relevant Taxing Jurisdiction became a Relevant Taxing Jurisdiction on a date after the Issue Date, on or after such later date), a Payor is or would be obligated, after taking commercially reasonable measures to avoid this requirement (it being understood that changing the jurisdiction of incorporation of a Payor or the location of a Payor’s principal executive or registered office shall not be a commercially reasonable measure), to pay any Additional Amounts following the date on which such amendment or change becomes effective; provided that no notice of redemption for tax reasons may be given earlier than 90 days prior to the earliest date on which the Payor would be obligated to pay these Additional Amounts if a payment on the Notes were then due.

Prior to the giving of any notice of redemption pursuant to this provision, the Company shall be required to deliver to the Trustee: (a) a certificate signed by one of the Company’s duly authorized representatives stating that the Company is entitled to effect the redemption and setting forth a statement of facts giving rise to such right of redemption, and (b) a written opinion of recognized counsel in the Relevant Jurisdiction to the effect that the Payor has or will become obligated to pay such Additional Amounts as a result of such change or amendment.

11.3	Optional Redemption

(1) Optional redemption on or prior to November 20, 2030 (the “first call date”). At any time and from time to time prior to November 20, 2030, the Notes shall be redeemable at the option of the Company in whole or in part, upon not less than ten nor more than 60 days’ notice to the Holders, and, if applicable, to the CNV, at a redemption price equal to the greater of:

(i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the first call date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points less (b) interest accrued to the date of redemption, and

(ii) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the redemption date.

“Treasury Rate” for this purpose means, with respect to any redemption date, the yield determined by us in accordance with the following two paragraphs.

The Treasury Rate shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the first call date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the first call date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

Exhibit 2.4.2 - 98

If on the third business day preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the first call date, as applicable. If there is no United States Treasury security maturing on the first call date but there are two or more United States Treasury securities with a maturity date equally distant from the first call date, one with a maturity date preceding the first call date and one with a maturity date following the first call date, the Company shall select the United States Treasury security with a maturity date preceding the first call date. If there are two or more United States Treasury securities maturing on the first call date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

(2)	Optional redemption on or after the first call date.

The Notes shall be redeemable, in whole or in part, at the option of the Company, at any time and from time to time on or after the first call date, subject to compliance with all relevant laws and regulations, upon not less than 10 nor more than 60 days’ notice to the Holders and, if applicable, to the CNV, in each of the periods indicated below and in the manner specified herein at a redemption price equal to the outstanding principal amount of the Notes to be redeemed multiplied by the applicable percentage set forth in the table below (the “Redemption Price”), together with accrued and unpaid interest thereon, if any (and any Additional Amounts thereon, if any), on the principal amount of such Notes to be redeemed to, but excluding, the redemption date.

	During the 12 Months Beginning		Applicable Percentage
	November 20, 2030		103.875%
	November 20, 2031		101.938%
	November 20, 2032		100.969%
	November 20, 2033 and thereafter		100.000%

(3)	Optional Redemption upon Equity Offering.

At any time and from time to time prior to November 20, 2028, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes (including, for greater certainty, any additional Notes) then Outstanding hereunder using the Net Cash Proceeds (and in an amount not greater than the aggregate of such Net Cash Proceeds) of one or more Equity Offerings, upon not less than ten nor more than 60 days’ notice to the Holders and, if applicable, to the CNV, at a redemption price of 107.750% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest, if any (and Additional Amounts thereon, if any), on the principal amount of such Notes to be redeemed to, but excluding, the redemption date; provided that:

Exhibit 2.4.2 - 99

1. at least 65% of the aggregate principal amount of the Notes originally issued hereunder on the Issue Date remain Outstanding immediately after the occurrence of such redemption; and

each such redemption occurs within 90 days of the date of the closing of any such Equity Offering.

11.4	Optional Redemption upon Certain Offers

In the event that Holders of not less than 85% of the aggregate principal amount of the Outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer, Asset Sale Offer or any other tender offer and the Company (or a third-party making the offer) purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company or third-party offeror, as applicable, will have the right, upon not less than 10 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to such offer described above, to redeem (in the case of the Company) or purchase (in the case of a third-party offeror) all of the Notes that remain outstanding following such purchase at a redemption price or purchase price, as the case may be, equal to the price paid to each other Holder in such offer (which shall be at least equal to par) (without including any early tender fee or payment) plus, to the extent not included in such price, accrued and unpaid interest, if any (and Additional Amounts thereon, if any), on the principal amount of such Notes to be redeemed to, but excluding, the applicable redemption or settlement date (subject to applicable DTC procedures and the right of Holders of record on the relevant Record Date to receive interest due on an interest Payment Date that is on or prior to the redemption or settlement date). In determining whether the Holders of at least 85% of the aggregate principal of the then outstanding Notes have validly tendered and not withdrawn such Notes in an offer, such calculation shall include all Notes owned by an Affiliate of any of the Company (notwithstanding any provision of the Indenture to the contrary).

11.5	Optional Redemption Procedures

(1)	Notes Redeemed in Part

In the event that less than all of the Notes are to be redeemed at any time, selection of Notes for redemption shall be made by the Trustee in compliance with the requirements governing redemptions of the principal securities exchange, if any, on which Notes are listed or if such securities exchange has no requirement governing redemption or the Notes are not then listed on a securities exchange, on a pro rata basis (pass-through distribution of principal) or by lot (or, in the case of Notes issued in global form, based on a method in accordance with the procedures of DTC). If Notes are redeemed in part, the remaining outstanding amount must be at least equal to US$1,000 and be an integral multiple of US$1,000 in excess thereof.

If Notes are to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed. A new Note in a principal amount equal to the unredeemed portion thereof, if any, shall be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note shall be made, as appropriate).

(2)	Election to Redeem; Notices

The election of the Company to redeem any Notes pursuant this Section 11.5 shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 3.1 for such Notes.

Exhibit 2.4.2 - 100

Notice of any redemption or purchase shall be given to the Holders in accordance with the provision set out under Section 1.6. Notice of any redemption or purchase shall be provided to the Trustee no later than five Business Days prior to the date that the notice of redemption or purchase is sent to Holders (or such shorter period as the Trustee may accept).

All notices of redemption shall state:

(i)

the Redemption Date,

(ii)

the Redemption Price,

(iii)

the CUSIP or other identifying number of such Notes to be redeemed,

(iv)

if less than all of the Outstanding Notes are to be redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Notes to be redeemed,

(v)

that, on the Redemption Date, the Redemption Price shall become due and payable upon each such Note to be redeemed and, if applicable, that interest thereon shall cease to accrue on and after said date,

(vi)

the place or places where, and the date by which, each such Note is to be surrendered for payment of the Redemption Price, and

(vii)

that the redemption is for a sinking fund, if such is the case.

(3)	Notes Payable on the Redemption Date

The Company shall pay the redemption price for any Note together with accrued and unpaid interest, if any (and Additional Amounts thereon, if any) on the principal amount of such Notes to be redeemed to, but excluding, the Redemption Date. On and after the Redemption Date, interest shall cease to accrue on Notes or portions thereof called for redemption as long as the Company has deposited with the Paying Agent funds in satisfaction of the applicable redemption price pursuant to the Indenture. Upon redemption of any Notes by the Company, such redeemed Notes shall be cancelled or, to the extent so requested by the Company, remain outstanding. The Company may designate at its option a third party to call the Notes for mandatory purchase in lieu of exercising its right to optional redemption hereunder; provided that any call by a third party shall be treated as if such call was made by the Company and the Company shall remain liable for any redemption payment in the event that the third party fails to make the redemption payment on the Redemption Date pursuant to these optional redemption procedures.

(4)	Deposit of Redemption Price

Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.4) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Notes which are to be redeemed on that date.

(5)	Redemption of Outstanding Notes Following a Change of Control Offer, Asset Sale Offer or other tender

(6)	Conditional Redemption

Exhibit 2.4.2 - 101

Notice of any redemption of the Notes may, at the Company’s discretion, be given prior to the completion thereof and any such redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, the completion of a related transaction such as an Equity Offering, an Incurrence of Indebtedness or a Change of Control. If such redemption or purchase is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Company’s discretion, the Redemption Date may be delayed for up to ten Business Days for such conditions to be satisfied, or such redemption or purchase may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. For the avoidance of doubt, interest shall continue to accrue on Notes, and the redemption price for any Notes to be redeemed shall include such accrued interest, for any period during which the redemption is delayed. In addition, the Company may provide in such notice that payment of the redemption price and performance of the Company’s obligations with respect to such redemption may be performed by another Person.

11.6	Purchase of Notes Upon Change of Control Event

Upon the occurrence of a Change of Control Event, each Holder shall have the right to require that the Company purchase all or a portion of the Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus Additional Amounts and accrued and unpaid interest thereon to, but excluding, the date of purchase (the “Change of Control Payment”).

Within 30 days following the date upon which a Change of Control Event occurred, the Company shall deliver a notice to each Holder describing the transaction or transactions that constitute(s) the Change of Control Event and offering to purchase the Notes as described above (a “Change of Control Offer”) as described in Section 1.6. The Change of Control Offer shall state, among other things, the purchase price, the purchase date (the “Change of Control Payment Date”), which must be no earlier than ten days nor later than 60 days from the date the notice is sent, except as may be required by law, and the procedures determined by the Company and consistent with the Indenture that a Holder of Notes must follow to have its Notes repurchased.

On the Business Day immediately preceding the Change of Control Payment Date, the Company shall, to the extent lawful, deposit with the applicable Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes.

On the Change of Control Payment Date, the Company shall, to the extent lawful:

(i)	accept for payment all Notes or portions of Notes (of US$1,000 or in integral multiples of US$1,000 in excess thereof) properly tendered and not withdrawn pursuant to the Change of Control Offer; and

(ii)	deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officer’s Certificate stating the principal amount of Notes being redeemed by the Company.

The Paying Agent shall promptly deliver to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and deliver (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unredeemed portion of the Notes surrendered, if any.

If only a portion of a Note is purchased pursuant to a Change of Control Offer, a new Note in a principal amount equal to the portion thereof not purchased shall be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note shall be made, as appropriate); provided that the remaining principal amount of such Holder’s Note shall not be less than US$1,000 and shall be in integral multiples of US$1,000 in excess thereof.

Exhibit 2.4.2 - 102

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws and regulations in connection with the purchase of Notes in connection with a Change of Control Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 11.6, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations by doing so. If it would be unlawful in any jurisdiction to make a Change of Control Offer, the Company shall not be obligated to make such offer in such jurisdiction and shall not be deemed to have breached its obligations hereunder by not making such an offer.

Except as otherwise provided in Article 9, the obligation of the Company to make a Change of Control Offer may be waived or modified at any time with the written consent of Holders of a majority in principal amount of the Outstanding Notes.

11.7	Open Market Purchases of Notes

The Company and its Subsidiaries and Affiliates may at any time purchase or otherwise acquire the Notes, by purchase or private agreement, in the open market or otherwise, at any price and may resell or otherwise dispose of such Notes at any time in accordance with applicable law, taking into account that, except as set forth in this Indenture, in order to determine at any time whether or not the Holders of the required principal amount of the Outstanding Notes have made a request, demand, authorization, instruction, notice, consent or waiver under the terms hereof, the Notes held by the Company or any of the Company’s Subsidiaries and Affiliates shall not be counted and shall not be considered Outstanding.

The provisions of this Article shall be applicable to any sinking fund for the retirement of Notes of any series except as otherwise specified as contemplated by Section 3.1 for such Notes.

The minimum amount of any sinking fund payment provided for by the terms of any Notes is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of such Notes is herein referred to as an “optional sinking fund payment.” If provided for by the terms of any Notes, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 12.2. Each sinking fund payment shall be applied to the redemption of Notes as provided for by the terms of such Notes.

12.2	Satisfaction of Sinking Fund Payments with Notes

The Company (1) may deliver Outstanding Notes of a series (other than any previously called for redemption) and (2) may apply as a credit Notes of a series which have been redeemed either at the election of the Company pursuant to the terms of such Notes or through the application of permitted optional sinking fund payments pursuant to the terms of such Notes, in each case in satisfaction of all or any part of any sinking fund payment with respect to any Notes of such series required to be made pursuant to the terms of such Notes as and to the extent provided for by the terms of such Notes; provided that the Notes to be so credited have not been previously so credited. The Notes to be so credited shall be received and credited for such purpose by the Trustee at the Redemption Price, as specified in the Notes so to be redeemed, for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly.

Exhibit 2.4.2 - 103

Not less than 45 days prior to each such sinking fund payment date, the Trustee shall select the Notes to be redeemed upon such sinking fund payment date in the manner specified in Section 11.3 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 11.5.

The Company may elect, at its option at any time, to have Section 13.2 or Section 13.3 applied to any Notes or any series of Notes, as the case may be, designated pursuant to Section 3.1 as being defeasible pursuant to such Section 13.2 or Section 13.3, in accordance with any applicable requirements provided pursuant to Section 3.1 and upon compliance with the conditions set forth below in this Article. Any such election shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 3.1 for such Notes.

13.2	Defeasance and Discharge

Upon the Company’s exercise of its option (if any) to have this Section applied to any Notes or any series of Notes, as the case may be, the Company shall be deemed to have been discharged from its obligations with respect to such Notes as provided in this Section on and after the date the conditions set forth in Section 13.4 are satisfied (hereinafter called “Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Notes and to have satisfied all its other obligations under such Notes and this Indenture insofar as such Notes are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of such Notes to receive, solely from the trust fund described in Section 13.4 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Notes when payments are due, (2) the Company’s obligations with respect to such Notes under Sections 3.4, 3.6, 3.7, 10.3 and 10.4, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article. Subject to compliance with this Article, the Company may exercise its option (if any) to have this Section applied to any Notes notwithstanding the prior exercise of its option (if any) to have Section 13.3 applied to such Notes.

13.3	Covenant Defeasance

For this purpose, such Covenant Defeasance means that, with respect to such Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case of Section 5.1(2)), whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any other provision herein or in any other document, but the remainder of this Indenture and such Notes shall be unaffected thereby.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 13.4 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 Outstanding Notes.

Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 13.4 with respect to any Notes which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Notes.

Exhibit 2.4.2 - 106

13.6	Reinstatement

If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Notes by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application or otherwise, then the obligations under this Indenture and such Notes from which the Company has been discharged or released pursuant to Section 13.2 or 13.3 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Notes, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 13.5 with respect to such Notes in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Note following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Notes to receive such payment from the money so held in trust.
