1.5.5    The Issuer may, but shall not be obligated to, in or pursuant to a Board Resolution, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action required or permitted to be taken pursuant to this Indenture. Notwithstanding Section 316(c) of the Trust Indenture Act, such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 calendar days prior to the first solicitation of Holders generally in connection therewith and not later than the date of such first solicitation. If a record date is fixed, notwithstanding the provisions of Clause 9.5 hereof, those Persons who were Holders of Notes at such record date (or their duly designated proxies), and only those Persons, shall be entitled to take any such action or give such consent or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date; provided, however, that unless such consent is obtained from the Holders (or their duly designated proxies) of the requisite principal amount of Notes that are outstanding prior to the date which is the 180th calendar day after such record date, any such consent previously given shall automatically and without further action by any Holder be cancelled and of no further effect.

1.6    Satisfaction and Discharge

This Indenture shall cease to be of further effect (except as to the rights of Holders under Clauses 2.5, 2.6, 2.8, 4.2 and 4.3 hereof) and the Trustee, on receipt of an Order requesting such action, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture (including the Guarantee contained herein), when (a) either (i) all outstanding Notes have been delivered to the Trustee for cancellation or (ii) all outstanding Notes have become due and payable, either at maturity or as a result of the mailing of a notice of redemption as described in Clause 3.1 hereof, and the Issuer, in the case of clause (ii) hereof, has irrevocably deposited or caused to be deposited with the Trustee, as funds held in trust, in cash in U.S. dollars, U.S. Government Obligations or a combination thereof, an amount which, in the opinion of a nationally recognised firm of independent public accountants expressed in a written certificate thereof delivered to the Trustee, is sufficient to pay and discharge the entire indebtedness on such Notes, for principal and interest to the date of such deposit (in the case of Notes which have become due and payable) or to the Redemption Date, as the case may be, together with irrevocable instructions from the Issuer in form and substance reasonably satisfactory to the Trustee directing the Trustee to apply such funds to the payment thereof; (b) the Issuer has paid or caused to be paid all other sums payable hereunder by the Issuer; and (c) the Issuer has delivered to the Trustee an Officer's Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for or relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture pursuant to this Clause 1.6, the obligations of the Issuer to the Trustee under Clause 7.7 hereof, and, if money

shall have been deposited with the Trustee in trust for the Holders pursuant to this Clause 1.6, the obligations of the Trustee under this Clause 1.6 and Clause 4.3 hereof, and the provisions hereof relating to the conduct of, affecting the liability of, or offering protection or immunity to, the Trustee, shall survive.

All money deposited with the Trustee pursuant to this Clause 1.6 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, to the Persons entitled thereto, of the principal and interest for the payment of which such money has been deposited with the Trustee. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Clause 1.6 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer's obligations under this Indenture and the Notes (and the obligations of the Guarantor under the Guarantee) shall be revived and reinstated as though no deposit had occurred pursuant to this Clause 1.6 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Clause 1.6; provided, that if the Issuer (or the Guarantor) has made any payment of interest on or principal of any Notes because of the reinstatement of its obligations, the Issuer (or the Guarantor) shall be subrogated to the rights of the Holders of such Notes to receive such payment from the cash or U.S. Government Obligations held by the Trustee or Paying Agent.

2      The Notes

2.1    Form and Dating

2.1.1    The Notes and the certificate of authentication of the Trustee thereon shall be substantially in the form of Exhibit A, which is hereby incorporated in and expressly made a part of this Indenture. The Notes will be issued only in fully registered form, without interest coupons attached, in minimum denominations of U.S.$2,000 and integral multiples thereof, and initially will be represented by the Global Notes. Except in the limited circumstances set forth herein, Certificated Notes will not be issued.

2.1.2    The Notes may have such letters, numbers or other marks of identification and such legends and endorsements, stamped, printed, lithographed or engraved thereon, (i) as the Issuer may deem appropriate and as are not inconsistent with the provisions of this Indenture, (ii) as may be required to comply with this Indenture, any law, rule or regulation or any rule of any securities exchange on which the Notes may be listed and (iii) as may be necessary to conform to customary usage. Each Note shall be dated the date of its authentication by the Trustee.

2.1.3    Notes sold in offshore transactions in reliance on Regulation S, as provided in the Purchase Agreement, will be represented by a single, permanent global Note (the "Regulation S Global Note") in fully registered form without interest coupons, substantially in the form of Exhibit A hereto. The Regulation S Global Note, duly executed by the Issuer and authenticated by the Trustee as hereinafter provided, on behalf of the subscribers for the Notes represented thereby, shall be deposited with, and registered in the name of a nominee of a common depositary for Clearstream and Euroclear. The aggregate principal amount of the Regulation S Global Note may from time to time be increased or decreased by adjustments made on the records of the common depositary as hereinafter provided.

2.1.4    Notes sold in reliance on Rule 144A, as provided in the Purchase Agreement, will be represented by a single, permanent global Note (the "Rule 144A Global Note") in fully registered form without interest coupons substantially in the form of Exhibit A hereto, with such legends as may be applicable thereto as provided in Exhibit A hereto, which shall be deposited on behalf of the subscribers for the Notes represented thereby with the Trustee, at its Corporate Trust Office, as custodian for the Depositary, and registered in the name of

Cede & Co. as nominee of the Depositary, duly executed by the Issuer and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the Rule 144A Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depositary, or the Depositary or its nominee, as the case may be, as hereinafter provided.

2.1.5    Except as provided in Clause 2.5.3, owners of beneficial interests in Global Notes will not be entitled to receive physical delivery of Certificated Notes.

2.2    Execution and Authentication

The Notes shall be issued in a single series. The Notes will not be limited in aggregate principal amount outstanding. The Notes shall be executed on behalf of the Issuer by a director by manual or facsimile signature.

The Notes shall be authenticated by manual or facsimile signature of an authorized signatory of the Trustee and shall not be valid for any purpose unless so authenticated.

In case any director of the Issuer whose signature shall have been placed upon any of the Notes shall cease to be such director of the Issuer before authentication of such Notes by the Trustee and the issuance and delivery thereof, such Notes may, nevertheless, be authenticated by the Trustee and issued and delivered with the same force and effect as though such Person had not ceased to be such director of the Issuer.

Upon receipt by the Trustee of an Officer's Certificate and Opinion of Counsel complying with Clause 11.4 hereof with respect to satisfaction of all conditions precedent contained in this Indenture to authentication and delivery of such Notes, the Trustee shall, upon receipt of an Order requesting such action, authenticate Notes for original issuance in an initial aggregate principal amount not to exceed U.S.$400,000,000 except with respect to Additional Notes issued pursuant to Clause 2.15 hereof. Such Order shall specify the amount of Notes to be authenticated and the date on which the Notes are to be authenticated and shall further provide instructions concerning registration, amounts for each Holder and delivery.

Upon the occurrence of any event specified in Clause 2.5.3 hereof, the Issuer shall execute and the Trustee, upon receipt of an Order requesting such action, shall authenticate and deliver to each beneficial owner identified by the Depositary, in exchange for such beneficial owner's interest in a Global Note, Certificated Notes representing Notes theretofore represented by such Global Note.

A Note shall not be valid or entitled to any benefit under this Indenture or obligatory for any purpose unless executed by the Issuer and authenticated by the manual signature of an authorized officer of the Trustee as provided herein. The signature of an authorized officer of the Trustee shall be conclusive evidence, and the only evidence, that such Note has been authenticated and delivered under this Indenture.

The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to authenticate the Notes. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.

The Trustee may at any time terminate the agency of the authenticating agent by giving written notice thereof to such authenticating agent and to the Issuer. Upon such termination, the Trustee may appoint a successor authenticating agent reasonably acceptable to the Issuer and shall mail at the Issuer's expense a written notice of such appointment by first class mail, postage prepaid, to all Holders as their names and addresses appear in the Security Register. Any successor authenticating agent upon acceptance of its appointment hereunder shall become vested with all rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an authenticating agent. The Issuer agrees to pay each authenticating agent from time to time reasonable compensation for its services under this Clause.

2.3    Registrar and Paying Agent

The Issuer shall maintain, pursuant to Clause 4.2 hereof, an office or agency where the Notes may be presented for registration of transfer or for exchange. The Issuer shall cause to be kept at such office a register (the register maintained in such office being herein sometimes referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Issuer shall provide for the registration of Notes and of transfers of Notes entitled to be registered or transferred as provided herein. The Trustee, at its Corporate Trust Office, is initially appointed "Registrar" for the purpose of registering Notes and transfers of Notes as herein provided. The Issuer may, upon written notice to the Trustee, change the designation of the Trustee as Registrar and appoint another Person (other than the Issuer, the Guarantor or any of their Affiliates) to act as Registrar for purposes of this Indenture. If any Person other than the Trustee acts as Registrar, the Trustee shall have the right at any time, upon reasonable notice, to inspect or examine the Security Register and to make such inquiries of the Registrar as the Trustee shall in its discretion deem necessary or desirable in performing its duties hereunder. The Trustee is initially appointed Paying Agent. The Issuer may, upon written notice to the Trustee, change the designation of the Trustee as Paying Agent, appoint another Person (other than the Issuer, the Guarantor or any of their Affiliates) to act as Paying Agent and thereafter change the designation of such Person as Paying Agent, appoint one or more supplemental Paying Agents (other than the Issuer, the Guarantor or any of their Affiliates) (whose appointment may be terminated by the Issuer upon notice to the Trustee), and approve (subject to Clause 4.2) any change in the specified office through which any Paying Agent acts. Notice of any termination or appointment of any Paying Agent shall be given to the Holders of the Notes in accordance with Clause 11.2 hereof. The Registrar and Paying Agent may resign at any time by giving 30 days prior written notice thereof to the Trustee and the Issuer.

The Issuer shall enter into an appropriate agency agreement with any Person designated by the Issuer as Registrar or Paying Agent that is not appointed pursuant to this Indenture, which agreement shall incorporate the provisions of the Trust Indenture Act and shall implement the provisions of this Indenture that relate to such Registrar or Paying Agent. Prior to the designation of any such Person, the Issuer shall, by written notice (which notice shall include the name and address of such Person), inform the Trustee of such designation. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such.

Notwithstanding any other provision hereof, the Issuer shall at all times maintain a Paying Agent and an office or agency where the Notes may be presented for registration of transfer or exchange in the Borough of Manhattan, The City of New York.

In addition to the foregoing, the Issuer hereby appoints J.P. Morgan Bank Luxembourg S.A., at its office at 5 Rue Plaetis, L-2338, Luxembourg, as Luxembourg Paying Agent. The Issuer may, upon written notice to the Luxembourg Paying Agent and the Trustee, revoke the designation of the Luxembourg Paying Agent, appoint another Person to act as Luxembourg Paying Agent and thereafter change the designation of such Person as Luxembourg Paying Agent, and (subject to Clause 4.2) approve any change in the specified office through which the Luxembourg Paying Agent acts. Notice of any termination or appointment of any Luxembourg Paying Agent shall be given to the Holders of the Notes in accordance with Clause 11.2 hereof. The Luxembourg Paying Agent may resign at any time by giving 30 days prior written notice thereof to the Trustee and the Issuer. Notwithstanding any other provision hereof, so long as the Notes are listed on the Luxembourg Stock Exchange and such stock exchange so requires, the Issuer shall maintain a Luxembourg Paying Agent for the Notes.

Subject to compliance with the provisions of Clause 2.1 hereof and the transfer restrictions of Clause 2.5 hereof, upon surrender for registration of transfer of any Note at an office or agency of the Issuer designated for such purpose, the Issuer shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations, of like tenor and aggregate principal amount, all as requested by the transferor.

Every Note presented or surrendered for registration of transfer or for exchange shall be duly endorsed, or be accompanied by a duly executed instrument of transfer in form satisfactory to the Issuer, the Trustee and the Registrar, by the Holder thereof or such Holder's attorney duly authorized in writing.

2.4    Global Notes

2.4.1    So long as a Global Note is registered in the name of the Depositary, the Common Depositary or a nominee or successor thereof, members of, or account holders, or participants in, the Depositary, the Common Depositary, or any successor or nominee thereof shall have no rights under this Indenture with respect to the Global Note held on their behalf by the Depositary, the Common Depositary, a nominee or successor thereof or the Trustee as custodian therefor, and the Depositary, the Common Depositary or their nominee or successor may be treated by the Issuer, the Guarantor, the Trustee or their agents as the sole owner of such Global Note for all purposes (except with respect to the determination of Additional Amounts owing). Notwithstanding the foregoing, nothing herein shall (i) prevent the Issuer, the Guarantor, the Trustee or any agent of the Issuer, the Guarantor or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by the Depositary, the Common Depositary or (ii) impair, as between the Depositary, the Common Depositary and their members, account holders or participants, the operation of customary practices governing the exercise of the rights of holders of beneficial interests in the Notes. For purposes of this Indenture, an "Agent Member" is a member of, or participant in, the Depositary, the Common Depositary, as the case may be and as the context may require, and includes, in the case of the Depositary, the Common Depositary.

2.4.2    The Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members of the Depositary and Persons that may hold interests in a Global Note through such Agent Members, to take any action which a Holder of Notes is entitled to take under this Indenture or the Notes.

2.4.3    Whenever, as a result of an optional redemption by the Issuer or of an exchange for Certificated Notes pursuant to the provisions of Clause 2.5.3 hereof, a Global Note is redeemed, repurchased or exchanged in part, such Global Note shall be surrendered by the Holder thereof to the Trustee who shall cause an adjustment to be made to Schedule A thereof so that the principal amount of such Global Note will be equal to the portion of such Global Note not redeemed, repurchased or exchanged and shall thereafter return such Global Note to such Holder, provided that each such Global Note shall be in a principal amount of U.S.$2,000 or integral multiples thereof.

2.5    Transfer and Exchange

2.5.1    Notwithstanding any provision to the contrary herein, so long as a Global Note remains outstanding and is held by or on behalf of the Depositary, the Common Depositary or a nominee or successor thereof, transfers of a Global Note, in whole or in part, shall only be made in accordance with this Clause 2.5; provided, however, that beneficial interests in a Global Note may be transferred to persons who take delivery thereof in the form of a beneficial interest in the same Global Note in accordance with the transfer restrictions set forth in the restricted securities legend on the Note and the customary procedures of the Depositary, the Common Depositary, as applicable, and the Agent Members.

2.5.2    The following provisions shall apply:

(i)

Rule 144A Global Note to Regulation S Global Note: If a holder of a beneficial interest in the Rule 144A Global Note deposited with the Depositary wishes at any time to exchange its interest in such Rule 144A Global Note for an interest in the Regulation S Global Note, or to transfer its interest in such Rule 144A Global Note to a Person who wishes to take delivery thereof in the form of an interest in the Regulation S Global Note, such holder may, subject to the rules and procedures of the Depositary, exchange or cause the

exchange or transfer or cause the transfer of such interest for an equivalent beneficial interest in the Regulation S Global Note. Upon receipt by the Trustee, as Registrar, at its Corporate Trust Office of (1) instructions given in accordance with the Depositary's procedures from the Agent Member directing the Trustee to credit or cause to be credited a beneficial interest in the Regulation S Global Note in an amount equal to the beneficial interest in the Rule 144A Global Note to be exchanged or transferred and (2) a certificate in the form of Exhibit B attached hereto given by the holder of such beneficial interest stating that the exchange or transfer of such interest has been made in compliance with the transfer restrictions applicable to the Notes and (A) pursuant to and in accordance with Regulation S or (B) that the Note being exchanged or transferred is not a "restricted security" as defined in Rule 144, the Trustee, as Registrar, shall in accordance with the Depositary's DWAC procedure reduce the Rule 144A Global Note by the aggregate principal amount of the beneficial interest in the Rule 144A Global Note to be so exchanged or transferred and the Trustee, as Registrar, shall instruct the Common Depositary for Euroclear or Clearstream, concurrently with such reduction, to increase the principal amount of the Regulation S Global Note by the aggregate principal amount of the beneficial interest in the Rule 144A Global Note to be so exchanged or transferred, and to credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Regulation S Global Note equal to the reduction in the principal amount of the Rule 144A Global Note.

(ii)

Regulation S Global Note to Rule 144A Global Note: If a holder of a beneficial interest in the Regulation S Global Note wishes at any time to exchange its interest in such Regulation S Global Note for an interest in the Rule 144A Global Note, or to transfer its interest in such Regulation S Global Note to a Person who wishes to take delivery thereof in the form of an interest in the Rule 144A Global Note, such holder may, subject to the rules and procedures of Euroclear or Clearstream and the Depositary, exchange or cause the exchange or transfer or cause the transfer of such interest for an equivalent beneficial interest in the Rule 144A Global Note. Upon receipt by the Trustee, as Registrar, as its Corporate Trust Office of (1) instructions given in accordance with the Depositary's procedures directing the Trustee, as Registrar, to credit or cause to be credited a beneficial interest in the Rule 144A Global Note equal to the beneficial interest in the Regulation S Global Note to be exchanged or transferred, such instructions to contain information regarding the Agent Member's account with the Depositary to be credited with such increase, and (2) a certificate in the form of Exhibit C attached hereto given by the holder of such beneficial interest and stating that the Person transferring such interest in the Regulation S Global Note reasonably believes that the person acquiring such interest in the Rule 144A Global Note is a QIB and is obtaining such beneficial interest in a transaction otherwise meeting the requirements of Rule 144A any applicable securities laws of any state of the United States and any other jurisdiction, the Trustee, as Registrar, shall instruct the Common Depositary for Euroclear or Clearstream to reduce the Regulation S Global Note by the aggregate principal amount of the beneficial interest to be exchanged or transferred, and the Trustee, as Registrar, shall in accordance with the Depositary's DWAC procedure, concurrently with such reduction, increase the principal amount of the Rule 144A Global Note by the aggregate principal amount of the beneficial interest in the Regulation S Global Note to be so exchanged or transferred, and to credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Note equal to the reduction in the principal amount of the Regulation S Global Note.



(iii)

Other Exchanges: In the event that a Global Note is exchanged for Certificated Notes pursuant to Clause 2.5.3 hereof, such Notes may be exchanged or transferred for one another only in accordance with such procedures as are substantially consistent with the provisions of clauses (i) and (ii) above (including the certification requirements intended to ensure that such exchanges or transfers comply with Rule 144, Rule 144A or

Regulation S, as the case may be) and as may be from time to time adopted by the Issuer and the Trustee.

(iv)

Beneficial Interests: Any beneficial interest in one of the Global Notes that is transferred to a person who takes delivery in the form of an interest in another Global Note, or exchanged for an interest in another Global Note, will, upon such transfer or exchange, cease to be an interest in the original Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer restrictions and other procedures applicable to a beneficial interest in such other Global Note for as long as it remains such a beneficial interest.

2.5.3    A Regulation S Global Note shall be exchanged for Certificated Notes if (a) Clearstream or Euroclear is closed for business for a continuous period of 14 days (other than by reason of holidays, statutory or otherwise) or announces an intention permanently to cease business and does in fact do so and no alternative clearing system satisfactory to the Issuer is available, or (b) the Issuer elects to exchange such Regulation S Global Note in whole but not in part for one or more Certificated Notes. A Rule 144A Global Note shall be exchanged by the Issuer for one or more Certificated Notes if (a) the Depositary (i) has notified the Issuer that it is unwilling or unable to continue as, or ceases to be, a clearing agency registered under Section 17A of the Exchange Act and (ii) a successor to the Depositary registered as a clearing agency under Section 17A of the Exchange Act is not able to be appointed by the Issuer within 90 calendar days, (b) the Depositary is at any time unwilling or unable to continue as Depositary and a successor to the Depositary is not able to be appointed by the Issuer within 90 calendar days, or (c) the Issuer elects to exchange such Rule 144A Global Note in whole but not in part for one or more Certificated Notes. In addition, if an Event of Default occurs and is continuing, the Issuer shall, at the request of the Holder thereof, exchange all or part of a Global Note for one or more Certificated Notes; provided that the principal amount of each of such Certificated Note, and such Global Note, after such exchange, shall be in minimum denominations of U.S.$2,000 or integral multiples thereof. Whenever a Global Note is exchanged as a whole for one or more Certificated Notes, it shall be surrendered by the Holder thereof to the Trustee for cancellation. Whenever a Global Note is exchanged in part for one or more Certificated Notes, it shall be surrendered by the Holder thereof to the Trustee and the Trustee shall make the appropriate notations thereon pursuant to Clause 2.4.3 hereof. All Certificated Notes issued in exchange for a Global Note or any portion thereof shall be in registered form and registered in such names, and delivered, as the Depositary, Euroclear or Clearstream, as applicable, shall instruct the Trustee. Any Certificated Notes issued pursuant to this Clause 2.5.3 shall include the Legend, except as set forth in Clause 2.5.9 hereof. The cost of preparing, printing, packaging and delivering any Certificated Notes shall be borne by the Issuer.

2.5.4    A Holder may transfer a Note only upon the surrender of such Note for registration of transfer at the specified office of the Registrar hereunder. No such transfer shall be effected until, and the transferee shall succeed to the rights of a Holder only upon, final acceptance and registration of the transfer in the Security Register by the Registrar. When Notes are presented to the Registrar with a request to register the transfer of, or to exchange, such Notes, the Registrar shall register the transfer or make such exchange as requested if its requirements for such transactions and any applicable requirements hereunder are satisfied. To permit registrations of transfers and exchanges of Certificated Notes, the Issuer shall execute and the Trustee shall authenticate Certificated Notes at the Registrar's request.

2.5.5    The Issuer shall not be required to make and the Registrar need not register the transfer or exchange of (i) any Note previously called for redemption pursuant to Clause 3 of this Indenture or (ii) any Certificated Note for a period of 15 calendar days preceding the due date for any payment of principal of or interest on such Certificated Note or the selection of such Certificated Note for redemption pursuant to Clause 3 of this Indenture.

2.5.6    No service charge shall be made for any registration of transfer or exchange of Notes, but the Issuer or the Trustee may require payment of a sum sufficient to cover any tax, fee or other governmental charge required by law that may be imposed in connection with any registration of transfer of Notes.

2.5.7    All Notes issued upon any registration of transfer or exchange pursuant to the terms of this Indenture will evidence the same debt and will be entitled to the same benefits under this Indenture as the Notes surrendered for such registration of transfer or exchange.

2.5.8    Holders of Notes (or holders of beneficial interests therein) and prospective purchasers designated by such Holders of Notes (or such holders of beneficial interests therein) shall have the right to obtain from the Guarantor upon request by such Holders (or such holders of beneficial interests) or prospective purchasers, during any period in which the Issuer is not subject to Section 13 or Section 15(d) of the Exchange Act or is not exempt from such reporting requirements pursuant to and in compliance with Rule 12g3-2(b) under the Exchange Act, the information required by paragraph (d)(4)(i) of Rule 144A in connection with any transfer or proposed transfer of such Notes or beneficial interests.

2.5.9    If Notes are issued upon the transfer, exchange or replacement of Notes not bearing the Legend, the Notes so issued shall not bear the Legend. If Notes are issued upon the transfer, exchange or replacement of Notes bearing the Legend, or if a request is made to remove the Legend on a Note, the Notes so issued shall bear the Legend, or the Legend shall not be removed, as the case may be, unless there is delivered to the Trustee evidence satisfactory to the Issuer, which may include an opinion of counsel licensed to practice law in the State of New York, the United States of America, as may be reasonably required by the Issuer that neither the Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A, Rule 144 or Regulation S and the securities laws of each other applicable jurisdiction, or that such Notes are not "restricted securities" within the meaning of Rule 144 and the Issuer and the Guarantor consent to such removal. Upon provision of such satisfactory evidence, the Trustee, at the written direction of the Issuer, shall authenticate and deliver a Note that does not bear the Legend. If the Legend is removed from the face of a Note and the Note is subsequently held by an Affiliate of the Issuer, the Issuer shall notify in writing the Registrar and the Legend shall be reinstated.

2.6    Replacement Notes

If any mutilated or defaced Note is surrendered to the Trustee, the Issuer shall execute and upon its written request the Trustee shall authenticate and deliver, in exchange and substitution for any such mutilated or defaced Note, a new Note containing identical provisions (including the same date of issuance) and of like principal amount, registered in the same manner, dated the date of its authentication, bearing interest from the date to which interest has been paid on the mutilated or defaced Note and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Issuer and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note and of the ownership of the applicant of such Note and (ii) such security or indemnity as may be required by them to save each of them and any agent of each of them harmless, then, in the absence of notice to the Issuer or the Trustee that such Note has been acquired by a protected purchaser, the Issuer shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Note, a new Note containing identical provisions (including the same date of issuance) and of like principal amount, registered in the same manner, dated the date of its authentication, bearing interest from the date to which interest has been paid on the destroyed, lost or stolen note and bearing a number not contemporaneously outstanding. Upon the issuance of any substituted Note, the Issuer may require the payment by the registered Holder thereof of a sum sufficient to cover fees and expenses connected therewith.

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

Upon the issuance of any new Note under this Clause 2.6, the Issuer may require the payment by the Holder 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 and its counsel) connected therewith.

Every new Note issued pursuant to this Clause 2.6 in lieu of any destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Issuer, 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 duly issued hereunder.

The provisions of this Clause 2.6 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.

2.7    Outstanding Notes

Notes outstanding at any time are all Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those paid pursuant to Clause 2.6 hereof and those described in this Clause 2.7 as not outstanding. A Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds such Note.

If a Note is replaced pursuant to Clause 2.6 hereof, it ceases to be outstanding unless the Trustee and the Issuer receive proof satisfactory to them that such replaced Note is held by a protected purchaser.

If the Paying Agent segregates and holds in trust or, in the case of the Luxembourg Paying Agent, on deposit in accordance with this Indenture, on a Redemption Date or Stated Maturity money sufficient to pay all principal and interest payable on that date with respect to the Notes to be redeemed or maturing, as the case may be, then on and after that date such Notes shall cease to be outstanding and interest on them shall cease to accrue.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent or any amendment, modification or other change to this Indenture, Notes held or beneficially owned by the Issuer, the Guarantor or any of their Affiliates or by agents of any of the foregoing shall be disregarded, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent or any amendment, modification or other change to this Indenture, only Notes which a Trust Officer actually knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee such pledgee's right so to act with respect to the Notes and that the pledgee is not the Issuer, the Guarantor or an Affiliate of the Issuer or the Guarantor or any of their agents.

2.8    Temporary Notes

Pending the preparation of definitive Notes, the Issuer may execute, and the Trustee shall authenticate, temporary notes (the "Temporary Notes") which are printed, lithographed, or otherwise produced, 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 officer executing the Notes may reasonably determine, as conclusively evidenced by such officer's execution of such Notes.

If Temporary Notes are issued, the Issuer shall cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the Temporary Notes shall be exchangeable for definitive Notes upon surrender of the Temporary Notes to the Trustee, without charge to the Holder. Until so exchanged, Temporary Notes will evidence the same debt and will be entitled to the same benefits under this Indenture as the definitive Notes in lieu of which they have been issued.

2.9    Cancellation

The Issuer at any time may deliver Notes to the Trustee for prompt cancellation. The Registrar, the Paying Agent and the Luxembourg Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange, purchase or payment. The Trustee shall cancel all Notes surrendered for registration of transfer, exchange, purchase, payment or cancellation and, upon a written order, shall return such cancelled Notes to the Issuer. The Issuer may not issue new Notes to replace Notes it has redeemed or paid or that have been delivered to the Trustee for cancellation.

2.10    Payment of Interest; Interest Rights Preserved

Subject to Clause 11.6, 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 such Note (or any predecessor Note) is registered at the close of business on the Record Date for such interest payment, which shall be the fifteenth calendar day immediately preceding such Interest Payment Date.

Any interest on any Note 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 registered Holder on the relevant Record Date, and, except as hereinafter provided, such Defaulted Interest, and any interest payable on such Defaulted Interest, shall be paid by the Issuer, at its election, as provided in Clause 2.10.1 or 2.10.2 below:

2.10.1    The Issuer may elect to make payment of any Defaulted Interest, and to the extent permitted by law, any interest payable on such Defaulted Interest, to the Persons in whose names the 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 Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on the Notes and the date of the proposed payment, and at the same time the Issuer 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 provided in this Clause 2.10.1. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 calendar days and not less than 10 calendar days prior to the date of the proposed payment and not less than 10 calendar days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Issuer of such Special Record Date and, in the name and at the expense of the Issuer, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be sent, first-class mail, postage prepaid, to each Holder at such Holder's address as it appears in the Security Register, not less than 10 calendar days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names the Notes are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause 2.10.2; or

2.10.2    The Issuer may make payment of any Defaulted Interest, and any interest payable on such Defaulted Interest, on the Notes in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuer to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Clause 2.10, 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.

2.11    Authorized Denominations

The Notes shall be issuable in minimum denominations of U.S.$2,000 and integral multiples thereof.

2.12    Computation of Interest

Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

2.13    Persons Deemed Owners

Prior to the due presentation for registration of transfer of any Note, the Issuer, the Trustee, any Paying Agent, the Registrar, the Luxembourg Paying Agent or any agent of any of them may deem and treat the Person in whose name such Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Note and for all other purposes whatsoever, whether or not such Note is overdue, and none of the Issuer, the Trustee, any Paying Agent, the Registrar, the Luxembourg Paying Agent or any agent of any of them shall be affected by notice to the contrary. All such payments so made to any such Person, or upon such Person's order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for money payable upon such Note.

2.14    CUSIP, Common Code and ISIN Numbers

The Issuer, in issuing the Notes, may use a "CUSIP," "Common Code" or "ISIN" number and, if so, the Trustee shall use the relevant CUSIP, Common Code or ISIN number in any notices to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the number printed in the notice or on the Notes and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer shall promptly notify the Trustee of any change in any number used.

2.15    Issuance of Additional Notes

The Issuer shall be entitled to issue Additional Notes under this Indenture which shall have identical terms as the Notes, other than with respect to the date of issuance, the issue price, the initial interest accrual date, and except as may be provided in Clause 2.15.3. The Additional Notes shall be issued in global registered form without interest coupons, substantially in the form of Exhibit A hereto.

The Notes and any Additional Notes shall be treated as a single class for all purposes under this Indenture.

With respect to any Additional Notes, the Issuer shall set forth in a Board Resolution and an Officer's Certificate, a copy of each which shall be delivered to the Trustee prior to the authentication thereof, the following information:

2.15.1    the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture;

2.15.2    the issue price, the issue date and the CUSIP, ISIN and Common Code numbers of such Additional Notes; provided, however, that no Additional Notes may be issued at a price that would cause such Additional Notes to have "original issue discount" within the meaning of Section 1273 of the U.S. Internal Revenue Code of 1986, as amended; and

2.15.3    whether such Additional Notes shall be issued in the form of a Rule 144A Global Note or a Regulation S Global Note.

2.16    Purchase of Notes by the Guarantor or Subsidiaries of the Guarantor

The Guarantor and each of the Subsidiaries of the Guarantor shall be entitled, to the extent permitted by applicable law, at any time, to purchase Notes in the open market at any price by tender or by any private arrangement pursuant to the terms and conditions of such tender or private arrangement and, to the extent permitted by, and pursuant to, the requirements of the Luxembourg Stock Exchange. Any Note that the Guarantor or any of the Subsidiaries of the Guarantor purchases may, at the option of the Guarantor, be surrendered to the Trustee for

cancellation. None of the notes that the Guarantor or any of the Subsidiaries of the Guarantor purchases may be reissued or resold, except to the Guarantor or any of its Subsidiaries.

3      Redemption

3.1    Notice of Redemption

If the Issuer elects to redeem Notes pursuant to Clause 7 thereof (relating to a tax redemption), it shall, at least 30 calendar days but not more than 60 calendar days before a Redemption Date, deliver to the Trustee and send to each Holder of Notes by first-class mail, postage prepaid, at the address of such Holder as it appears in the Security Register, a written notice stating:

3.1.1    the Redemption Date;

3.1.2    the Redemption Price (and shall specify the portion of such Redemption Price that constitutes the amount of accrued and unpaid interest to be paid, if any);

3.1.3    that the Notes are being called for redemption pursuant to Clause 7 thereof;

3.1.4    that, unless the Issuer defaults in the payment of the Redemption Price with respect thereto, interest on the Notes called for redemption shall cease and such Notes shall cease to accrue interest, from and after the Redemption Date;

3.1.5    that the Notes called for redemption must be surrendered to any Paying Agent to collect the Redemption Price;

3.1.6    the name and address of the Paying Agent(s); and

3.1.7    any other information necessary to enable Holders to comply with the notice of redemption.

3.2    Notice to Trustee

The Issuer shall notify the Trustee in writing of the Redemption Date and the principal amount of Notes to be redeemed. The Issuer shall give each such notice to the Trustee at least 60 calendar days prior to the Redemption Date unless the Trustee consents to a shorter period, and in any event prior to the time notice is delivered to Holders pursuant to Clause 3.1 of this Indenture. Such notice shall be accompanied by an Officer's Certificate stating that the Issuer is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Issuer to so redeem the Notes have occurred, and an Opinion of Counsel of recognized international standing to the effect that such redemption will comply with any conditions to such redemption set forth herein and in the Notes.

3.3    Effect of Notice of Redemption

Once notice of redemption is mailed, Notes called for redemption shall become due and payable on the Redemption Date and at the Redemption Price stated in such notice. Upon surrender to any Paying Agent such Notes shall be paid at the Redemption Price stated in such notice. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

3.4    Deposit of Redemption Price

On or prior to 10:00 a.m., New York City time, on the business day immediately preceding the Redemption Date, the Issuer shall deposit with the Paying Agent, U.S. Dollars in immediately available funds, sufficient to pay the Redemption Price in respect of all Notes to be redeemed other than Notes called for redemption which have been delivered by the Issuer to the Trustee for cancellation. The Paying Agent shall promptly send by first-class mail, postage prepaid, to each Holder of Notes to be redeemed, payment in an amount equal to the Redemption Price for such Notes.

So long as the Issuer complies with the preceding paragraph and the other provisions of this Clause 3, interest on the Notes to be redeemed on the Redemption Date shall cease to accrue

from and after such date and such Notes shall be deemed not to be entitled to any benefit under this Indenture except to receive payment of the Redemption Price on the Redemption Date (subject to the right of each Holder of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date occurring on or before the Redemption Date). If any Note called for redemption shall not be so paid upon surrender for redemption, then, from the Redemption Date until such principal is paid, interest shall be paid on the unpaid principal and, to the extent permitted by law, on any accrued but unpaid interest thereon, at the rate prescribed therefor by such Notes.

4      Covenants

4.1    Payment of Principal and Interest

The Issuer shall promptly pay the principal of and interest on the Notes in United States Dollars on the dates and in the manner provided in the Notes and in Clause 4.3 hereof. Principal and interest shall be considered paid on the date due if, on such date, the Trustee or any Paying Agent holds in accordance with this Indenture money sufficient to pay all principal and interest then due.

To the extent lawful, the Issuer shall pay interest on (i) any overdue principal of the Notes, at the interest rate borne by the Notes and (ii) Defaulted Interest (without regard to any applicable grace period), at the same rate. The Issuer's obligation pursuant to the previous sentence shall apply whether such overdue amount is due at the Stated Maturity of the Notes, as a result of the Issuer's obligations pursuant to Clause 3.4, or otherwise.

Interest on the Notes shall be paid by U.S. dollar check drawn on a bank in The City of New York or, for Holders of at least $1,000,000 of Notes, by wire transfer to a U.S. dollar account maintained by the payee with a bank in The City of New York provided that a written request from such Holder to such effect designating such account is received by the Trustee or a Paying Agent no later than the Record Date immediately preceding such Interest Payment Date. Unless such designation is revoked, any such designation made by such person with respect to such Note will remain in effect with respect to any future payments with respect to such Note payable to such person. The Issuer will pay any administrative costs imposed by banks in connection with making payments by wire transfer.

Payments in respect of principal on the Notes shall be made against surrender of such Notes.

4.2    Maintenance of Office or Agency

The Issuer and the Guarantor shall maintain in the Borough of Manhattan, The City of New York, an office or agency where Notes may be presented or surrendered for payment, where Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Issuer and the Guarantor in respect of the Notes and this Indenture may be served. The Issuer or the Guarantor shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer and the Guarantor shall fail to maintain 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 Issuer and the Guarantor each hereby appoints the Trustee its agent to receive all such presentations, surrenders, notices and demands.

The Issuer and the Guarantor may also from time to time designate one or more other offices or agencies (in or outside of The City of New York) where the Notes may be presented or surrendered for any or all of such purposes, and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Issuer of its obligation to maintain an office or agency in The City of New York for such purposes. The Issuer shall give prompt written notice to the Trustee of any such designation and any change in the location of any such other office or agency.

For so long as the Notes shall remain listed on the Luxembourg Stock Exchange and the Luxembourg Stock Exchange shall so require, the Issuer shall maintain the appointment of a Luxembourg Paying Agent.

4.3    Payments; Money for the Note Payments to be Held in Trust

4.3.1    The Issuer shall, no later than the business day immediately preceding each due date of the principal of, or interest or Additional Amounts on any of the Notes, deposit, or cause the Guarantor to deposit on its behalf, with the Paying Agent, at its office in London, as principal paying agent, by wire transfer in U.S. dollars and in immediately available funds, a sum sufficient to pay the principal, interest or Additional Amounts so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, interest or Additional Amounts. Unless the Paying Agent is the Trustee, the Paying Agent shall promptly notify the Trustee of the Issuer's action or failure so to act according to this Clause 4.3.1.

4.3.2    The Issuer shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by such Paying Agent for the payment of principal of or interest on the Notes, shall notify the Trustee of any default by the Issuer in making any such payment and at any time during the continuance of any such default, upon the written request of the Trustee, shall forthwith pay to the Trustee all sums held in trust by such Paying Agent.

4.3.3    The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Clause 4.3, the Paying Agent shall have no further liability for the money delivered to the Trustee.

4.3.4    Any funds paid by the Issuer to the Trustee or any Paying Agent in trust or, in the case of the Luxembourg Paying Agent, on deposit for the payment of the principal, interest or Additional Amounts on the Notes that remains unclaimed for two years after the date upon which such payment shall have become due, shall be promptly repaid to the Issuer without interest upon receipt by the Trustee of an Order to that effect; provided, however, that the Issuer shall cause to be published at least once in a newspaper of general circulation in The City of New York and in Europe (and Luxembourg, for so long as any Notes are listed on the Luxembourg Stock Exchange) or mailed to each Holder entitled to such unclaimed funds, notice that such funds remain unclaimed and that, after a date specified therein, which shall be a date not less than 30 days from the date of such publication or mailing, any unclaimed balance of such money remaining as of such date shall be repaid to the Issuer without interest. Holders shall not be entitled to receive interest on such unclaimed funds under any circumstances. After repayment to the Issuer, Holders entitled to such funds shall look only to the Issuer for payment without interest thereon, as unsecured general creditors, and the Issuer shall not be liable to pay any taxes or other duties in connection with any such payment. The Trustee and the Paying Agent shall have no further liability with respect to any such money repaid to the Issuer, and the Issuer shall not be a trustee in respect of such funds. Notwithstanding any other provision of this Clause and unless otherwise provided by applicable law, the right to receive payment of principal of any Note (whether at maturity, redemption or otherwise) will become void at the end of 10 years from the relevant date thereof (or such shorter period as may be prescribed by applicable law).

4.4    Corporate Existence

Except as permitted in Clause 5 hereof, the Issuer and the Guarantor shall do or cause to be done all things necessary to preserve and keep in full force and effect the corporate existence, rights (by charter and statutory), licenses and franchises of the Issuer, the Guarantor and each of the Subsidiaries of the Guarantor; provided that the Guarantor and any of its Subsidiaries shall not be required to preserve the corporate existence of any such Subsidiary (other than the Issuer) or any such right, license or franchise if the board of directors of the Guarantor shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Guarantor and its

Subsidiaries and that the loss thereof is not disadvantageous in any material respect to the Holders of Notes or owners of beneficial interests therein.

4.5    Limitation on Incurrence of Debt

The Guarantor will not, and will not permit any of its Subsidiaries to, create, issue, incur, assume, guarantee or in any manner become directly or indirectly liable with respect to, or otherwise become responsible for (collectively, "incur") any Debt, including any Acquired Debt, unless the ratio of the Guarantor's total outstanding Debt to annualized Consolidated Cash Flows (as determined by multiplying the Guarantor's Consolidated Cash Flows for the two most recent fiscal quarters by two) would be no greater than 4.0 to 1.0, determined on a pro forma basis after giving pro forma effect to such incurrence and the incurrence of any other Debt and any other changes in the Guarantor's Debt since the date of the Guarantor's most recently available quarterly or annual consolidated balance sheet and the application of the net proceeds therefrom as if it had occurred on the first date of such quarterly or annual period.

For the purposes of calculating this ratio, any acquisitions that have been made by the Guarantor or a Subsidiary of the Guarantor, including through mergers or consolidations and including any related financing transactions, during or subsequent to the relevant fiscal quarter or year and on or prior to the date of the calculation of the ratio shall be deemed to have occurred on the first day of the relevant fiscal quarter or year, with the pro forma determinations of Consolidated Cash Flows resulting from any such transactions as determined in good faith by the Guarantor.

The accrual of interest, the accretion or amortization of original issue discount and the payment of interest on any Debt in the form of additional Debt with the same terms will not deemed to be an incurrence of Debt for purposes of this covenant.

4.6    Negative Pledge

The Issuer and the Guarantor will not, and the Guarantor will not permit any Subsidiary to, create, assume or permit to exist any Debt secured by Lien (other than a Permitted Lien) upon or in respect of any of its or their property or assets, now owned or hereafter acquired, without effectively providing that the Notes and the Guarantee shall be directly secured equally and rateably with the Debt secured by such Lien.

This restriction will not apply to a Lien created to secure Attributable Debt in connection with a Sale and Lease-Back Transaction permitted under Clause 4.7 hereof.

4.7    Limitation on Sale and Lease-Back Transactions

The Issuer and the Guarantor will not, and the Guarantor will not permit any Subsidiary to, enter into any sale and Lease-Back Transaction with respect to any of its property or assets, now owned or hereafter acquired, unless after giving effect to the Sale and Lease-Back Transaction, the aggregate amount of all Attributable Debt relating to all Sale and Lease-Back Transactions plus all outstanding secured Debt created, incurred or assumed by the Guarantor and the Subsidiaries of the Guarantor does not exceed 10 per cent. of the book value of the Guarantor's total assets, as determined by reference to the Guarantor's most recent quarterly or annual consolidated balance sheet on a pro forma basis after giving effect to the incurrence of any Debt and any other changes in the Guarantor's Debt since the date of such balance sheet. For the purposes of this determination, the amount of Debt under any secured credit facility will be the total amount available under the facility, regardless of the amount at any one time outstanding.

This Clause 4.7 will not apply to transactions between the Guarantor and one of the Subsidiaries of the Guarantor or between such Subsidiaries or to a Sale and Lease-Back Transaction where the Issuer, the Guarantor or such Subsidiary would be entitled pursuant to Clause 4.6 hereof to incur Debt secured by a Lien on the property or assets subject to the Sale and Lease-Back Transaction without equally and rateably securing the Notes and the Guarantee.

4.8    Change in Control

So long as any Note remains outstanding, if a Change in Control occurs, each Holder will have the right to require the Issuer to redeem the Notes of such Holder at a Redemption Price equal to 101 per cent. of the principal amount of such Notes plus accrued interest.

Within 30 days after the occurrence of a Change in Control, the Issuer will deliver to the Holders, the Trustee and the Luxembourg Paying Agent notice of the Change in Control and of the resulting redemption right. Upon receipt by the Trustee or the Luxembourg Paying Agent (for so long as the Notes are listed on the Luxembourg Stock Exchange) from a Holder, on or before the 30th day after the date of the Issuer's notice referred to in the previous sentence, of (a) a properly completed notice in the form of Exhibit D hereto, together with (b) the Notes of such Holder, the Issuer will redeem such Notes no earlier than 30 and no later than 60 days after the date of the Issuer's notice of the Change in Control.

A holder may not exercise this redemption right in the event the Issuer has already exercised its option to redeem the Notes as described in Clause 7 of the Notes (relating to tax redemption).

4.9    Reports

4.9.1    The Guarantor shall (i) file with the Commission or otherwise make public and deliver to the Trustee, within 180 days of the end of each fiscal year, an annual report on Form 20-F (or any successor form) containing the information required to be contained therein (or in such successor form), regardless of whether the Guarantor is then required to file a Form 20-F under the rules promulgated by the Commission; (ii) make public and deliver to the Trustee, within 120 days of the end of each fiscal year, reports for the fourth quarter of such fiscal year containing its consolidated balance sheet, statement of operations and cash flow statement prepared in accordance with U.S. GAAP (but excluding footnotes) and a discussion by its management highlighting critical financial developments during the fourth quarter; and (iii) submit to the Commission or otherwise make public and furnish to the Trustee, within 60 days of the end of the first three fiscal quarters of each fiscal year, quarterly reports on Form 6-K (or any successor form) containing its consolidated balance sheet, statement of operations and cash flow statement prepared in accordance with U.S. GAAP (but excluding footnotes) and a discussion by its management highlighting critical financial developments during the period. In addition, the Guarantor has agreed that, during any period in which it is not subject to and in compliance with Section 13 or 15 (d) of the Exchange Act or is not exempt from such reporting requirements pursuant to and in compliance with Rule 12g3-2(b) under the Exchange Act, it will provide to each Holder of the Notes (or holder of a beneficial interest therein) and to each prospective purchaser of the Notes (as designated by such Holder or holder of a beneficial interest), upon the request of such Holder, prospective purchaser or holder of a beneficial interest in the Notes, any information required to be provided by Rule 144A(d)(4) under the Securities Act.

4.9.2    After this Indenture has been qualified under the Trust Indenture Act, the Issuer and the Guarantor shall file with the Trustee and the Commission, and transmit to Holders, such information, documents and other reports, and such summaries thereof, as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant to such Act; provided that any such information, documents or reports required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the Trustee within 15 days after the same is so required to be filed with the Commission.

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

4.10    Compliance Certificate; Notice of Default or Event of Default

4.10.1    The Issuer and the Guarantor shall each deliver to the Trustee on the first anniversary of the Issue Date, and on each anniversary thereafter so long as any Note remains outstanding, an Officer's Certificate stating whether or not, to the best knowledge of such officers, the Issuer or the Guarantor, as the case may be, has complied with all conditions and covenants under this Indenture, and, if the Issuer or the Guarantor, as the case may be, shall be in Default, specifying all such Defaults and the nature thereof of which such officer may have knowledge.

For the purposes of this Clause 4.10.1, compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

4.10.2    The Issuer and the Guarantor shall each deliver written notice to the Trustee promptly after any executive officer of the Issuer or the Guarantor, as the case may be, becomes aware of the occurrence of any event which constitutes a Default or Event of Default, describing such Default or Event of Default, its status and what action the Issuer or the Guarantor, as the case may be, is taking or proposes to take with respect thereto.

4.11    Payment of Additional Amounts.

All payments by the Issuer in respect of the Notes and the Indenture and by the Guarantor in respect of the Guarantee and the Indenture will be made free and clear of and without deduction or withholding for or on account of any present or future taxes, duties, assessments, fees or other governmental charges ("Taxes") imposed or levied by or on behalf of Luxembourg, the Russian Federation, any jurisdiction from or through which a payment is made or any political subdivision or taxing authority thereof or therein (each, a "Taxing Jurisdiction"), unless such withholding or deduction is required by law. If the Issuer is required to make any withholding or deduction for or on account of any Taxes from any payment made under or with respect to the Notes, or if the Guarantor is required to make any withholding or deduction for or on account of any Taxes imposed by a Taxing Jurisdiction from any payment made under or with respect to the Guarantee, the Issuer will pay (or, in respect of the Guarantee, the Guarantor will pay) as additional interest to any Holder of the Notes such additional amounts (the "Additional Amounts") as may be necessary in order that every net payment made by the Issuer on such Note or by the Guarantor on the Guarantee after deduction or withholding for or on account of any Taxes will not be less than the amount then due and payable on such Note or the Guarantee. The foregoing obligation to pay Additional Amounts, however, will not apply to any (i) Taxes that would not have been imposed but for the existence of any present or former connection between such Holder of the Notes and any Taxing Jurisdiction other than the mere receipt of such payment or the ownership or holding of such Note, (ii) Taxes that would not have been imposed but for the presentation by the Holder of such Note for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later, (iii) Taxes required to be deducted or withheld by any Paying Agent from a payment on a Note or the Guarantee, if such payment can be made without deduction or withholding by any other Paying Agent, (iv) Taxes that would not have been imposed but for the failure of the Holder to comply with the Issuer's written request addressed to the Holder at least 60 days prior to the relevant payment to provide information with respect to any reasonable certification, documentation, information or other reporting requirement concerning the nationality, residence, identity or connection with the Taxing Jurisdiction of the Holder of such Note, (v) Taxes imposed on a payment to an individual that are required to be made pursuant to European Union Directive 2003/48/EC or any other European Union Directive implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000 on the taxation of savings income or any law implementing or complying with, or introduced in order to conform to, such Directive and (vi) estate, inheritance, gift, sale or excise tax. The Guarantee also applies to Additional Amounts payable by the Issuer.

The Issuer or the Guarantor, as the case may be, shall make any such withholding or deduction for or on account of Taxes and shall remit the full amount deducted or withheld to the relevant authority in accordance with the applicable law. The Issuer or the Guarantor, as the case may be, shall furnish to the Holders of Notes that are outstanding on the date of the required payment within 30 days after the date the payment of any Taxes is due pursuant to applicable law, certified copies of tax receipts evidencing that such payment has been made by the Issuer or the Guarantor, as the case may be. The Issuer and the Guarantor shall indemnify and hold harmless each Holder on the date of the required payment of any Taxes and upon written request reimburse each such Holder for the amount of (i) any Taxes (other than net income taxes) levied on and paid by such Holder as a result of payments made under or with respect to the outstanding Notes or the Guarantee, (ii) any liability (other than any liability relating to any net income taxes) (including penalties, interest and expense) arising therefrom or with respect thereto, and (iii) any Taxes imposed with respect to any reimbursement under clause (i) or (ii) above.

At least 30 days prior to each date on which any payment under or with respect to the Notes or the Guarantee is due and payable, if the Issuer or the Guarantor, as the case may be, becomes obligated to pay Additional Amounts with respect to such payment, the Issuer or the Guarantor, as the case may be, shall deliver to the Trustee (and each Paying Agent other than the Trustee) an Officer's Certificate certifying that the Issuer will make a withholding or deduction for or on account of Taxes and remit the same to the relevant authority, attesting to the fact that such Additional Amounts will be payable and the amounts so payable, and setting forth such other information as is necessary to enable the Trustee to pay such Additional Amounts to the Holders on the payment date. Whenever in this Indenture there is mentioned, in any context, the payment of principal, interest (including Defaulted Interest) or any other amount payable on or with respect to any of the Notes or the Guarantee, such reference shall be deemed to include mention of the payment of Additional Amounts provided for in this Clause 4.11 to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this Clause 4.11, and express mention of the payment of Additional Amounts in certain provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made.

The Issuer and the Guarantor, jointly and severally, hereby covenant to indemnify the Trustee (and each other Paying Agent) (which shall include their respective directors, officers, employees and agents) for, and to hold it harmless against any loss, liability or reasonable expenses incurred without gross negligence, bad faith or wilful misconduct on such Person's part, arising out of or in connection with actions taken or omitted by any of them in reliance on any Officer's Certificate furnished pursuant to this Clause 4.11 or the failure of the Trustee (or other Paying Agent) for any reason (other than its own gross negligence, bad faith or wilful misconduct) to receive on a timely basis such Officer's Certificate.

A Default under Clause 6.1.4 is not an Event of Default unless the notice provided for in such clause specifies the Default, demands that it be remedied and states that the notice is a "Notice of Default."

6.2    Acceleration

If an Event of Default (other than an Event of Default specified in Clause 6.1.12 or Clause 6.1.13) occurs and is continuing, then and in every such case the Trustee by written notice to the Issuer and the Guarantor, or the Holders of at least 25 per cent. in aggregate principal amount of the Notes then outstanding by written notice to the Issuer, the Guarantor and the Trustee, may declare the unpaid principal of and any accrued interest on all the Notes then outstanding to be immediately due and payable. Upon such declaration such principal and interest shall be due and payable immediately. If an Event of Default specified in Clause 6.1.12 or Clause 6.1.13 hereof occurs, such an amount shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

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 or the Holders under this Indenture, the Holders of a majority in principal amount of the Notes then outstanding, by written notice to the Issuer, the Guarantor and the Trustee, may rescind and annul such declaration and its consequences if: (a) the Issuer or the Guarantor has paid or deposited with the Trustee a sum sufficient to pay (i) all overdue instalments of interest on the Notes, (ii) the principal of any Notes which have become due otherwise than by such declaration of acceleration and interest thereon at the rate borne by the Notes, (iii) to the extent that payment of such interest is lawful, interest upon overdue instalments of interest at the rate borne by the Notes, and (iv) all sums paid or advanced by the Trustee hereunder and reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and (b) all Events of Default, other than the non-payment of the principal of and interest on the Notes which have become due solely by such acceleration, have been cured or waived as provided in this Indenture. No such rescission shall affect any subsequent Default or impair any right consequent thereon.

6.3    Other Remedies

The Issuer covenants that if an Event of Default specified in Clause 6.1.1 or Clause 6.1.2 occurs the Issuer shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders, the whole amount then due and payable on the Notes for principal and interest and, to the extent that payment of such interest shall be legally enforceable, interest upon the overdue principal and upon Defaulted 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 and all other amounts due to the Trustee pursuant to Clause 7.7 hereof.

If the Issuer fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Issuer and the Guarantor or any other obligor upon such Notes and

collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property and assets of the Issuer and the Guarantor or any other obligor upon such Notes, wherever situated.

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

6.4    Waiver of Past Defaults

The Holders of not less than a majority in principal amount of the Notes then outstanding may, on behalf of the Holders of all the Notes, waive any past or existing Default or Event of Default and its consequences under this Clause 6, except a Default or Event of Default (a) in the payment of the principal of or interest on, any Note, or (b) in respect of a covenant or provision hereof which under Clause 9.2 hereof cannot be modified or amended without the consent of the Holder of each outstanding Note affected thereby.

6.5    Control by Majority

Subject to the provisions of Clause 7.2.8 hereof, the Holders of not less than a majority in principal amount of the Notes then outstanding shall have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes; provided that

6.5.1    such direction shall not be in conflict with any rule of law or with this Indenture or unduly prejudicial to the rights of other Holders and would not subject the Trustee to personal liability;

6.5.2    the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; and

6.5.3    such Holder or Holders have offered to the Trustee security or indemnity satisfactory to the Trustee in its reasonable discretion against the costs, expenses and liabilities to be incurred in compliance with such request.

6.6    Limitation on Suits

No Holder of Notes 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:

6.6.1    such Holder has previously given written notice to the Trustee of a continuing Event of Default;

6.6.2    the Holders of not less than 25 per cent. in principal amount of the Notes then outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

6.6.4    the Trustee for 60 calendar days after its receipt of such notice, request and offer of security or indemnity has failed to institute any such proceeding.

in any such event, it being understood and intended that no one or more Holders of Notes 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 Holders of Notes, 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 rateable benefit of all Holders of Notes.

6.7    Rights of Holders to Receive Payment

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, or any premium or interest on, or the Redemption Price of, the Notes held by such Holder when due, or to bring suit for the enforcement of any such payment, shall be absolute and unconditional and shall not be impaired or affected without the consent of such Holder.

6.8    Trustee May File Proofs of Claim

Nothing contained herein 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.

6.9    Priorities

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, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defences made by such party litigant; but the provisions of this Clause shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10 per cent. in principal amount of the Notes then outstanding, or to any suit instituted by any Holder for the enforcement of the payment of the principal of any Note on or after its Stated Maturity or interest thereon after the date upon which payment thereof is due.

6.11    Trustee May Enforce Claims Without Possession of Notes

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.

6.14    Delay or Omission Not Waiver

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

(i)

semi-annually, not less than 10 calendar days prior to each Interest Payment Date, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Holders as of the Record Date immediately preceding such Interest Payment Date, and



(ii)

at such other times as the Trustee may request in writing, within 30 calendar days after the receipt by the Issuer of any such request, a list of similar form and content as of a date not more than 15 calendar days prior to the time such list is furnished;

provided, however, that if and so long as the Trustee shall be the Registrar for the Notes, no such list need be furnished with respect to the Notes.

7.6.2    The Trustee shall preserve, in as current a form as is reasonably practicable, the names and addresses of Holders contained in the most recent list furnished to the Trustee as provided in Clause 7.6.1 hereof and the names and addresses of Holders received by the Trustee in its capacity as Registrar, if so acting. The Trustee may destroy any list furnished to it as provided in Clause 7.6.1 hereof upon receipt of a new list so furnished.

7.6.3    Holders may communicate as provided in Section 312(b) of the Trust Indenture Act with other Holders with respect to their rights under this Indenture or under the Notes.

7.6.4    Each Holder of Notes, by receiving and holding the same, agrees with the Issuer and the Guarantor and the Trustee that none of the Issuer, the Guarantor or the Trustee shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Holders in accordance with this Clause 7.6, regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under this Clause 7.6.

7.6.5    Within 60 calendar days after 15 May, the Trustee shall transmit by mail to all Holders of Notes, a brief report dated as of 15 May if and to the extent required under Section 313(a) of the Trust Indenture Act.

The Issuer or the Guarantor shall promptly notify the Trustee of any stock exchange upon which the Notes are listed.

7.7    Compensation and Indemnity

The Issuer shall pay to the Trustee from time to time such compensation as the Issuer and the Trustee shall agree in writing for its services. The Issuer shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by the Trustee in accordance with any provision of this Indenture, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements

and advances of the Trustee's agents and counsel. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust.

The Issuer and the Guarantor, jointly and severally, shall indemnify each of the Trustee (which shall include, for purposes of this subsection, its directors, officers, employees and agents) and any predecessor Trustee for, and hold it harmless against, any and all loss, damage, claim, liability or expense (including reasonable attorneys' fees and expenses) arising out of or incurred by it in connection with the acceptance or administration of the trust created by this Indenture and the performance of its duties and the exercise of its rights and powers hereunder, except as set forth in the next paragraph. The Trustee shall notify the Issuer and the Guarantor promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer or the Guarantor shall not relieve the Issuer or the Guarantor, respectively, of its obligations hereunder. The Issuer and the Guarantor shall defend any such claim and the Trustee shall cooperate in the defence of such claim and neither the Issuer, Guarantor nor the Trustee shall enter into any settlement agreement without the written consent of the other parties, which consents shall not be unreasonably withheld. The Trustee may have separate counsel and the Issuer and the Guarantor, jointly and severally, shall pay the reasonable fees and expenses of such counsel.

The Issuer and the Guarantor need not reimburse any loss, damage, claim, liability or expense or indemnify against any loss, damage, claim, liability or expense incurred by the Trustee through the Trustee's own wilful misconduct, negligence or bad faith.

To secure the Issuer's and the Guarantor's payment obligations in this Clause 7.7, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Notes.

The Issuer's and the Guarantor's payment obligations pursuant to this Clause 7.7 shall survive the resignation or removal of the Trustee and discharge of this Indenture. Subject to any other rights available to the Trustee under applicable Bankruptcy Law, when the Trustee incurs expenses after the occurrence of a Default specified in Clause 6.1.12 or Clause 6.1.13 hereof, the expenses are intended to constitute expenses of administration under Bankruptcy Law.

The Issuer and the Guarantor will use their best efforts to pay the acceptance fee and the first annual administrative fee of the Trustee, as well as the fees and expenses of the Trustee's counsel, if any, promptly upon receipt of an invoice therefor.

The Issuer and the Guarantor, jointly and severally, shall indemnify the Luxembourg Paying Agent and hold it harmless against, any and all loss, damage, claim, liability or expense (including reasonable attorneys' fees and expenses) arising out of or incurred by it in connection with the performance of its duties and the exercise of its rights and powers hereunder in its capacity as the Luxembourg Paying Agent, except as set forth in the next paragraph. The Luxembourg Paying Agent shall notify the Issuer and the Guarantor promptly of any claim for which it may seek indemnity. Failure by the Luxembourg Paying Agent to so notify the Issuer or the Guarantor shall not relieve the Issuer or the Guarantor, respectively, of its obligations hereunder. The Issuer and the Guarantor shall defend any such claim and the Luxembourg Paying Agent shall cooperate in the defence of such claim and neither the Issuer, Guarantor nor the Luxembourg Paying Agent shall enter into any settlement agreement without the written consent of the other parties, which consents shall not be unreasonably withheld. The Luxembourg Paying Agent may have separate counsel and the Issuer and the Guarantor, jointly and severally, shall pay the reasonable fees and expenses of such counsel. The Issuer and the Guarantor need not pay for any settlement made without their respective consents, which consents shall not be unreasonably withheld.

The Issuer and the Guarantor need not reimburse any loss, damage, claim, liability or expense or indemnify against any loss, damage, claim, liability or expense incurred by the Luxembourg Paying Agent through the Luxembourg Paying Agent's own wilful misconduct, negligence or bad faith.

7.8.2    The Trustee may resign at any time by giving written notice thereof to the Issuer. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 calendar days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee.

7.8.3    The Trustee may be removed at any time by Act of the Holders of a majority in principal amount of the Notes then outstanding, delivered to the Trustee, the Issuer and the Guarantor.

7.8.5    If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Issuer, by or pursuant to a Board Resolution, shall promptly appoint a successor Trustee.

Upon the Issuer's exercise of its option to have this Clause 8.2 applied to the outstanding Notes, each of the Issuer and the Guarantor shall be deemed to have been discharged from its obligations with respect to the Notes and the Guarantee, respectively, as provided in this Clause 8.2 on and after the date the conditions set forth in Clause 8.4 hereof are satisfied (hereinafter called "Legal Defeasance").

With the consent of the Holders of at least a majority in principal amount of the Notes then outstanding, by Act of said Holders delivered to the Issuer and the Trustee, the Issuer, the Guarantor and the Trustee may amend this Indenture or the Notes or enter into one or more 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 or waiving in any manner the rights of the Holders; provided that no such amendment, supplemental indenture or waiver shall, without the consent of the Holder of each outstanding Note,

9.2.1    change the Stated Maturity or the time for payment of interest of any Note;

9.2.2    reduce the principal amount or the rate of interest, including Defaulted Interest, on any Note;

9.2.3    reduce the amount payable upon a redemption of any Note or alter or waive any provision with respect to the redemption of any Note (other than provisions relating to the covenants described under Clause 4.8);

9.2.4    amend or modify any payment obligation of the Guarantor under Clause 10 hereof;

9.2.5    change the place of payment of any Note (other than changes to or additions or removals of a Paying Agent made in accordance with the provisions of this Indenture) or make any Note payable in a currency other than United States Dollars;

9.2.6    impair the right of the Holders to institute suit for the enforcement of any payment on any Note;

9.2.7    reduce the percentage of Holders who must consent to an amendment or supplement of this Indenture;

9.2.8    modify any provision of this Indenture dealing with modification or waiver;

9.2.11    change the obligation of the Issuer or the Guarantor to pay Additional Amounts.

It shall not be necessary for any Act of Holders under this Clause 9.2 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.

After an amendment or supplement under this Clause 9.2 becomes effective or a waiver under Clause 6.4 becomes effective the Issuer or the Trustee at the Issuer's request and expense, shall mail to Holders of Notes a notice briefly describing such amendment, supplement or waiver. The failure to give such notice to all Holders of Notes, or any defect therein, shall not impair or affect the validity of an amendment, supplement or waiver. Notwithstanding any other provision hereof, to the extent that any amendment to this Indenture involves the transfer of the obligations of the Issuer or the Guarantor under the Notes or the Guarantee, respectively, to another Person, or the substitution of another Person for the Issuer or the Guarantor, the Issuer, the Guarantor and such other Person shall provide written notice of such transfer or substitution to the Holders of the Notes.

9.3    Effect of Supplemental Indentures

Upon the execution of any supplemental indenture under this Clause 9, 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.

9.4    Compliance with Trust Indenture Act

Every amendment or supplement to this Indenture or the Notes shall comply with the Trust Indenture Act as then in effect as though this Indenture were qualified thereunder.

9.5    Revocation and Effect of Consents and Waivers

A consent to an amendment, supplement or a waiver by a Holder of a Note shall bind the Holder and every subsequent Holder of such Note or portion of such Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent or waiver is not made on such Note; provided that any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder's Note or portion of such Note if the Trustee receives the notice of revocation before

the date the amendment, supplement or waiver becomes effective. After an amendment, supplement or waiver becomes effective pursuant to this Clause 9, it shall bind every Holder.

9.6    Notation on or Exchange of Notes

If a supplemental indenture changes the terms of a Note, the Trustee may require the Holder thereof to deliver such Note to the Trustee. The Trustee may place an appropriate notation on such Note regarding the changed terms and return it to the Holder. Alternatively, if the Issuer or the Trustee so determines, the Issuer in exchange for such Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or to issue a new Note shall not affect the validity of such amendment or supplement.

9.7    Trustee to Execute Supplemental Indentures

The Trustee shall execute any supplemental indenture authorized pursuant to this Clause 9 if such supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but shall not be required to, execute such supplemental indenture. In executing any supplemental indenture, the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and to receive, and (subject to Clause 7.1 hereof) shall be fully protected in relying upon, an Officer's Certificate (which need only cover the matters set forth in Clause 9.7.1 below) and an Opinion of Counsel reasonable satisfactory to the Trustee provided by the Issuer and the Guarantor stating in effect that:

9.7.1    such supplemental indenture is authorized or permitted by this Indenture and that all conditions precedent to the execution, delivery and performance of such supplemental indenture have been satisfied;

9.7.2    the Issuer or the Guarantor, as the case may be, has all necessary corporate power and authority to execute and deliver the supplemental indenture and that the execution, delivery and performance of such supplemental indenture has been duly authorized by all necessary corporate action of the Issuer and the Guarantor, as the case may be;

9.7.3    the execution and delivery of the supplemental indenture do not conflict with, or result in the breach of or constitute a default under any of the terms, conditions or provisions of the Indenture;

9.7.4    such supplemental indenture has been duly and validly executed and delivered by the Issuer or the Guarantor, as the case may be, and the Indenture together with such supplemental indenture constitutes a valid and binding obligation of the Issuer or the Guarantor enforceable against the Issuer or the Guarantor, as the case may be, in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency or similar laws affecting the enforcement of creditors' rights generally and general equitable principles; and

9.7.5    the Indenture together with such amendment or supplement complies with the Trust Indenture Act.

Such opinion may be subject to exceptions, limitations and qualifications, including with respect to the opinion in Clause 9.7.4 hereof (i) the effect of bankruptcy, insolvency, reorganization, moratorium, or other similar laws now or hereafter in effect relating to or affecting the rights or remedies of creditors and the judicial application of foreign laws or governmental actions affecting creditors' rights; (ii) the effect of general principles of equity, whether enforcement is considered in a proceeding in equity or at law and the discretion of the court before which any proceeding therefor may be brought; (iii) the unenforceability under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy; and (iv) the unenforceability of any provision requiring the payment of attorney's fees, except to the extent that a court determines such fees to be reasonable. In addition, such Opinion of Counsel is not required to express an opinion with respect to whether acceleration of the Notes may affect the collectibility of that portion of the stated principal amount thereof which might be determined to

constitute unearned interest thereon or concerning the enforceability of the waiver of rights or defences regarding stay, extension or usury laws.

10    Guarantee

10.1    Guarantee

Subject to the provisions of this Clause 10, the Guarantor hereby irrevocably and unconditionally guarantees to each Holder and to the Trustee on behalf of the Holders (i) the due and punctual payment of principal of and interest in full on each Note when and as the same shall become due and payable whether at Stated Maturity, by declaration of acceleration, redemption or otherwise and the due and punctual payment of all other sums stated in this Indenture and the Notes to be payable pursuant to this Indenture and the Notes, including, without limitation, any Additional Amounts; (ii) the due and punctual payment of interest on the overdue principal of and interest in full on the Notes, to the extent permitted by law; and (iii) the due and punctual performance of all other duties, agreements, covenants and obligations of the Issuer to the Holders or the Trustee, including without limitation the payment of fees, expenses, indemnification or other amounts, all in accordance with the terms of the Notes and this Indenture. The Guarantor hereby further agrees to pay any and all expenses (including reasonable fees and expenses of counsel) incurred by the Trustee or the Holders in enforcing any rights under the Guarantee.

Each of the Issuer and the Guarantor hereby unconditionally waives diligence, presentment, demand of payment, filing of claims with a court in the event of merger, insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer or any other Person, protest or notice with respect to the Notes or the Debt evidenced thereby and all demands whatsoever, and covenants that the Guarantee will not be discharged except by complete performance of the obligations contained in the Notes, in this Indenture and pursuant to the Guarantee.

The Guarantor further agrees that, as between the Guarantor, on the one hand, and Holders and the Trustee, on the other hand, (i) for purposes of the Guarantee, the maturity of the obligations guaranteed by such Guarantee may be accelerated as provided in Clause 6, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed thereby, and (ii) in the event of any acceleration of such obligations (whether or not due and payable) such obligations shall forthwith become due and payable by the Guarantor for purposes of the Guarantee.

The Guarantee shall continue to be effective or shall be reinstated, as the case may be, if at any time any payment, or any part thereof, of principal of or interest on any of the Notes is rescinded or must otherwise be returned by the Holders or the Trustee upon the insolvency, bankruptcy or reorganization of the Issuer or the Guarantor, all as though such payment had not been made.

The Guarantor shall be subrogated to all rights of the Holders against the Issuer in respect of any amounts paid by the Guarantor pursuant to the provisions of the Guarantee or this Indenture; provided, however, that the Guarantor shall not be entitled to enforce or to receive any payments until the principal of and interest on all Notes issued hereunder shall have been paid in full.

Where the context so requires in this Indenture, payments by the Guarantor under the Guarantee shall be construed to be payments on or in respect of the Notes.

10.2    Obligations of the Guarantor Unconditional

The Guarantor hereby agrees that its obligations hereunder shall be a guarantee of payment and shall be unconditional, irrespective of and unaffected by the validity, regularity or enforceability of the Notes or this Indenture, or of any amendment thereto or hereto, the absence of any action to enforce the same, the waiver or consent by any Holder or by the Trustee with respect to any provisions thereof or of this Indenture, the entry of any judgment against the Issuer or any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defence of a guarantor.

10.3    Limitation of the Guarantor's Liability

The Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy Law, the U.S. Uniform Fraudulent Conveyance Act, the U.S. Uniform Fraudulent Transfer Act or any similar law of the United States or any state thereof or any foreign jurisdiction. To effectuate the foregoing intention, the Holders and the Guarantor hereby irrevocable agree that the obligations of the Guarantor under this Clause 10 shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of the Guarantor, result in the obligations of the Guarantor under the Guarantee not constituting a fraudulent transfer or conveyance.

10.4    Application of Certain Terms and Provisions to the Guarantor

(a)

For purposes of any provision of this Indenture which provides for the delivery by the Guarantor of an Officer's Certificate and/or an Opinion of Counsel, the definitions of such terms in Clause 1.1 hereof shall apply to the Guarantor as if references therein to the Issuer were references to the Guarantor.



(b)

Any request, direction, order or demand which by any provision of this Indenture is to be made by the Guarantor, shall be sufficient if evidenced by an Order; provided that the definition of such term in Clause 1.1 hereof shall apply to the Guarantor as if references therein to the Issuer were references to the Guarantor.



(c)

Any notice or demand which by any provision of this Indenture is required or permitted to be given or served by the Trustee or by the Holders of Notes to or on the Guarantor may be given or served as described in Clause 11.2 as if references therein to the Issuer were references to the Guarantor.



(d)

Upon any demand, request or application by the Guarantor to the Trustee to take any action under this Indenture, the Guarantor shall furnish to the Trustee such certificates and opinions as are required in Clause 11.3 and Clause 11.4 hereof as if all references therein to the Issuer were references to the Guarantor.

10.5    Taxes

The Guarantor shall pay Additional Amounts as required pursuant to Clause 4.11 of this Indenture. The Guarantor shall pay and indemnify the Trustee and the Holders against all documentary, stamp or other similar taxes payable in connection with the execution, delivery or enforcement of this Guarantee. The obligations of the Guarantor under this Clause 10.5 shall survive the termination of this Indenture and the Guarantee and the payment of all amounts under or with respect to this Indenture, the Guarantee and the Notes.

11    Miscellaneous

11.1    Trust Indenture Act Controls

If and to the extent that any provision of this Indenture limits, qualifies or conflicts with the duties imposed by, or with another provision (an "incorporated provision") included in this Indenture by operation of, Sections 310 to 318, inclusive, of the Trust Indenture Act, such imposed duties or incorporated provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

11.2    Notices

Any notice or communication mailed to a Holder shall be sent to the Holder by first-class mail, postage prepaid, at the Holder's address as it appears in the Security Register and shall be duly given if so sent within the time prescribed. Failure to mail a notice or communication to a Holder or any defect in it shall not affect its sufficiency with respect to other Holders. If a notice or communication is mailed to a Holder in the manner provided in this paragraph, it is duly given, whether or not the addressee receives it. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give notice by mail to Holders, 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 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.

So long as the Notes are listed on the Luxembourg Stock Exchange and the Luxembourg Stock Exchange shall so require, notice shall also be given by publication in a leading newspaper of general circulation in Luxembourg.

11.3    Certificate and Opinion as to Conditions Precedent

Upon any request or application by the Issuer to the Trustee to take or refrain from taking any action under this Indenture, the Issuer shall furnish to the Trustee upon request: (a) an Officer's Certificate stating that, in the opinion of the signers, all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with; and (b) an Opinion of Counsel reasonably satisfactory to the Trustee stating that, in the opinion of such counsel, all such conditions precedent have been complied with.

11.5    Rules by Trustee, Paying Agent and Registrar

The Trustee may make reasonable additional rules for action by or a meeting of Holders consistent with provisions of this Indenture, and any Registrar and Paying Agent may make reasonable rules for their functions; provided that no such rule shall conflict with terms of this Indenture or the Trust Indenture Act.

11.6    Date of Payments

If any payment on a Note is due on a Saturday, Sunday, legal holiday, or a day that is, in Moscow, Luxembourg or New York, a day on which banking institutions are authorized or obligated by law or executive order to close, then, in Moscow, Luxembourg or New York, such payment need not be made on such day but may be made on the next succeeding day that is not a Saturday, Sunday, legal holiday, or a day that is, in Moscow, Luxembourg or New York, a day on which banking institutions are authorized or obligated by law or executive order to close (a "business day"), with the same force and effect as if made on the date for such payment, and no interest will accrue for the period from and after the date for such payment.

        If a regular Record Date is a date that is not a business day, such Record Date shall not be affected.

11.7    Governing Law

11.7.1    This indenture, the guarantee and the notes shall be governed by, and construed in accordance with, the laws of the state of New York without regard to the principles of conflicts of laws thereof.

11.7.2    The application of Articles 86-94-8 of the Luxembourg law on commercial companies of 10 August 1915 (as amended) has been excluded in respect of the notes.

11.8    No Recourse Against Others

No director, officer, employee, incorporator or stockholder of the Issuer or the Guarantor, as such, shall have any liability for any obligations of the Issuer or the Guarantor, as the case may be, under the Notes, the Guarantee or this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation, solely by reason of its status as a director, officer, employee, incorporator or stockholder of the Issuer or the Guarantor, as the case may be. By

accepting a Note, each Holder waives and releases all such liability (but only such liability) as part of the consideration for issuance of such Note to such Holder.

11.9    Successors

All agreements of each of the Issuer and the Guarantor in this Indenture and the Notes shall bind its successors and assigns whether so expressed or not. All agreements of the Trustee in this Indenture shall bind its successors and assigns whether so expressed or not.

11.10    Counterparts

This Indenture may be executed in any number of counterparts and by the parties thereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

11.11    Table of Contents; Headings

The table of contents and headings of the Clauses of this Indenture have been inserted for convenience of reference only, are not intended to be considered a part hereof and shall not modify or restrict any of the terms or provisions hereof.

11.12    Severability

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.

11.13    Further Instruments and Acts

Upon request of the Trustee, the Issuer and the Guarantor will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

11.14    Jurisdiction

11.14.1    The Issuer and Guarantor each agrees that any suit, action or proceeding against the Issuer or the Guarantor brought by any Holder or the Trustee arising out of or based upon this Indenture, the Guarantee or the Notes may be instituted in any State or Federal court in the Borough of Manhattan in The City of New York, New York, and waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the non-exclusive jurisdiction of such courts in any suit, action or proceeding. Each of the Issuer and the Guarantor has appointed Puglisi & Associates, with offices on the date hereof at 850 Library Avenue, Suite 204, Newark, Delaware 19715 as its respective authorized agent (the "Authorized Agent") upon whom process may be served in any suit, action or proceeding arising out of or based upon this Indenture, the Guarantee or the Notes which may be instituted in any State or Federal court in The City of New York, New York, and expressly accepts the non-exclusive jurisdiction of any such court in respect of any such suit, action or proceeding. The Issuer and the Guarantor hereby represent and warrant that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and the Issuer and the Guarantor agree to take any and all commercially reasonable action, including the filing of any and all documents that may be reasonably necessary to continue each such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent in any manner permitted by applicable law shall be deemed, in every respect, effective service of process upon the Issuer and Guarantor, respectively.

11.14.2    Notwithstanding Clause 11.14.1, any action involving the Issuer or the Guarantor arising out of or based upon this Indenture, the Guarantee or the Notes may be submitted to arbitration, as provided in Clause 11.15 hereof.

11.14.3    To the extent that either the Issuer or the Guarantor has or hereafter may acquire any immunity (sovereign or otherwise) from any legal action, suit or proceedings, from jurisdiction of any court or from set-off or any legal process (whether service of process or

notice, attachment in aid or otherwise) with respect to itself or any of its property, the Issuer and the Guarantor hereby irrevocably waive and agree not to plead or claim such immunity in respect of their obligations under this Indenture.

11.15    Arbitration

11.15.1    The Issuer and the Guarantor agree that any controversy, claim or cause of action brought by any party against any other party or arising out of or relating to this Indenture, the Guarantee or the Notes which cannot be settled amicably may be settled by arbitration in accordance with the Rules of the London Court of International Arbitration, which rules are deemed to be incorporated by reference into this Clause 11.15. The place of the arbitration shall be London, England and the language of the arbitration shall be English. The number of arbitrators shall be three, appointed by the London Court of International Arbitration in accordance with its Rules. The arbitrators shall have no authority to award punitive or other damages and may not, in any event, make any ruling, finding or award that does not conform to the terms and conditions of this Indenture, the Guarantee or the Notes. In no circumstances shall the Trustee be liable for any consequential, special or punitive damages in connection with its obligations hereunder.

11.15.2    Fees of the arbitration (excluding each party's preparation, travel, attorneys' fees and similar costs) shall be borne in accordance with the decision of the arbitrators. The decision of the arbitrators shall be final, binding and enforceable upon the parties and judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction thereof. In the event that the failure of a party to comply with the decision of the arbitrators requires any other party to apply to any court for enforcement of such award, the non-complying party shall be liable to the other for all costs of such litigation, including reasonable attorneys' fees.

12    Provisions for Meetings of Holders of Notes

12.1    Holders' Meetings

12.1.1    The Trustee may at any time call a meeting of the Holders by notice to the Holders not less than 30 days prior to such meeting, for the purpose of approving a modification or amendment to, or obtaining a waiver of, any provision of this Indenture or the Notes or to consider any other matter of common interest to the Holders. In addition, in case at any time the Issuer or the Guarantor pursuant to a Board Resolution, or the Holders of at least one-tenth in aggregate principal amount of the Notes then outstanding, shall have requested the Trustee to call a meeting of the Holders, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have made the first giving of the notice of such meeting within 20 days after receipt of such request, then the Issuer, the Guarantor or the Holders of the amount above specified may determine the time (not less than 30 days after notice is given) and may call such meeting by giving notice thereof as provided below. Any such meeting will be held in London.

12.1.2    Meetings of Holders are subject to a first and second notice; the second to occur upon the failure of the first. Both the first and second notice convening a meeting of Holders may be made simultaneously, in which case the meeting convened by the second notice, upon the failure of the first, may be held within an hour of such failure. The quorum for the first notice will be persons holding or representing at least two-thirds in aggregate principal amount of Notes then outstanding (other than Notes held by the Issuer, the Guarantor, any Affiliate of the Issuer or the Guarantor, or the Trustee in its individual capacity). 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 then outstanding (other than Notes held by the Issuer, the Guarantor, any Affiliate of the Issuer or the Guarantor, or the Trustee in its individual capacity).

12.1.3    If a meeting is being held pursuant to the written request of Holders, the agenda for the meeting shall be as determined in the request and such meeting shall be held within 40 days from the date such written request is received by the Trustee or the Issuer, as the case may be. Notice of any meeting of Holders, setting forth the time and place of such meeting and in general terms the action proposed to be taken at such meeting, shall be given by publication for five successive business days in leading newspapers having general circulation (i) in the Borough of Manhattan, City of New York, (ii) in Europe and (iii) in Luxembourg and as specified in the Notes, not less than 10 or more than 30 days prior to the date fixed for the meeting. To be entitled to vote at any meeting of Holders a person shall be (i) a Holder of one or more Notes as of the relevant record date determined pursuant to Clause 1.5.5 or (ii) a person or persons appointed by an instrument in writing as proxy by such a Holder of one or more Notes (other than directors, officers or any employee of the Issuer, the Guarantor or any of their Affiliates). The only persons who shall be entitled to be present or to speak at any meeting of Holders shall be the persons entitled to vote at such meeting and their counsel and any representatives of the Trustee, the Issuer or the Guarantor and their counsel.

12.1.4    Any Holder who has executed an instrument in writing appointing a person or persons as proxy shall be deemed to be present for the purposes of determining a quorum and be deemed to have voted; provided, that such Holder shall be considered as present or voting only with respect to the matters covered by such instrument in writing. Except as otherwise provided in this Indenture, the Notes or any applicable law, any resolution passed or decision taken at any meeting of Holders duly held in accordance with this Clause shall be binding on all the Holders whether or not present or represented at the meeting.

12.1.5    Notwithstanding any other provision of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any action by or any meeting of Holders, in regard to the proof of the holding of Notes and of the appointment of proxies, and in regard to the appointment and duties of inspectors of votes, and submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think appropriate. Such regulations may fix a record date and time for determining the Holders of record of Notes entitled to vote at such meeting, in which case those and only those Persons who are Holders of Notes at the record date and time so fixed, or their proxies, will be entitled to vote at such meeting whether or not they will be such Holders at the time of the meeting.

12.1.6    The Trustee shall, by any instrument in writing, appoint a person to act on its behalf as representative of the Holders to serve as chairperson of the meeting. If the Trustee fails to appoint such a person, then, another representative of the Holders shall be designated to act as chairperson of the meeting by vote of a majority in aggregate principal amount of the Notes represented at the meeting. A secretary of the meeting shall be elected by vote of the Holders or proxies of a majority in aggregate principal amount of the Notes represented at the meeting. At any meeting each Holder or proxy shall be entitled to one vote for each U.S.$1,000 principal amount of Notes held or represented by him; provided, that no vote shall be cast or counted at any meeting in respect of any Note challenged as not outstanding and ruled by the chairperson of the meeting to be not outstanding. The chairperson of the meeting shall have no right to vote except as a Holder or proxy. Any meeting of Holders duly called at which a quorum is present may, upon motion of the chairperson, be adjourned once and reconvened within 30 days without further notice.

12.1.7    Any duly passed resolution of Holders of Notes, and any instrument given by or on behalf of any Holder of a Note in connection with any consent to any modification, amendment or waiver of the Indenture or the terms and conditions of the Notes will be

irrevocable once given and will be conclusive and binding on all subsequent Holders of such Notes. Any modifications, amendments or waivers to the terms and conditions of the Notes duly passed, in accordance with the requirements provided in Clause 12.1.8 below, at a duly convened meeting of Holders of Notes will be conclusive and binding on all Holders of Notes, whether or not they voted in favour of such resolution or were present at any meeting, and whether or not notation of such modifications, amendments or waivers is made upon the Notes.

12.1.8    Subject to Clause 9.2 of this Indenture, decisions shall be made by the affirmative vote of Holders of Notes or their proxies representing at least a majority in aggregate principal amount of the Notes represented at the meeting.

12.1.9    The vote upon any resolution submitted to any meeting of Holders shall be by written ballot on which shall be subscribed the signatures of the Holders or proxies and on which shall be inscribed the serial number or numbers of the Notes held or represented by them.

In witness whereof, the parties hereto have caused this Indenture to be duly executed as of the day and year first above written.

REVERSE SIDE OF GLOBAL NOTE

Mobile TeleSystems Finance S.A.

GLOBAL NOTE REPRESENTING 8.00 per cent. SENIOR NOTES DUE 2012

1      Indenture

This Note is one of a duly authorized issue of debt securities of the Issuer (as defined below) designated as its "8.00 per cent. Senior Notes due 2012" (herein called the "Notes"), issued under an indenture dated as of 28 January 2005 (as amended or supplemented from time to time, the "Indenture") among Mobile TeleSystems Finance S.A., as issuer (including any successors or assigns under the Indenture, the "Issuer"), Mobile TeleSystems OJSC, as guarantor (including any successors or assigns under the Indenture, the "Guarantor"), JPMorgan Chase Bank, N.A., as trustee (the "Trustee," which term includes any successor trustee under the Indenture) and J.P. Morgan Bank Luxembourg S.A., as Luxembourg paying agent (the "Luxembourg Paying Agent", which term includes any successor Luxembourg paying agent under the Indenture). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders of Notes are referred to the Indenture and such Act for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuer, the Guarantor, the Trustee and each Holder of Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The summary of the terms of this Note contained herein does not purport to be complete and is qualified by reference to the Indenture. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control. All capitalized terms used in this Note which are not defined herein shall have the meanings assigned to them in the Indenture.

The Indenture restricts, among other things, the Issuer's and the Guarantor's ability to incur Debt, to incur Liens to secure Debt, to engage in Sale and Lease-Back Transactions, to merge or consolidate with any other Person, and to sell, transfer, lease, convey or otherwise dispose of substantially all of its or their properties or assets, and the Guarantor's ability to sell, transfer, lease, convey or otherwise dispose of certain assets.

2      Principal and Interest

The Issuer promises to pay the principal amount set forth on Schedule A of this Note to the Holder hereof on 28 January 2012.

The Issuer shall pay interest at an annual rate of 8.00 per cent., from the Issue Date or from the most recent Interest Payment Date thereafter to which interest has been paid or duly provided for, semi-annually in arrear on 28 January and 28 July in each year (each such date, an "Interest Payment Date"), commencing on 28 July 2005, in cash, to the Holder hereof until the principal amount hereof is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, subject to certain exceptions provided in the Indenture, be paid to the Person in whose name this Note (or the Note in exchange or substitution for which this Note was issued) is registered at the close of business on the Record Date for interest payable on such Interest Payment Date. The Record Date for any interest payment is the close of business on the fifteenth calendar day prior to the relevant Interest Payment Date, as the case may be, whether or not a business day, immediately preceding the Interest Payment Date on which such interest is payable. Any such interest not so punctually paid or duly provided for ("Defaulted Interest") shall forthwith cease to be payable to the Holder on such Record Date and shall be paid as provided in Clause 2.10 of the Indenture. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

Each payment of interest in respect of an Interest Payment Date will include interest accrued through the day before such Interest Payment Date. If any payment on this Note is due on a day that is, in the City of New York or at any other place of payment, a day on which banking institutions are authorized or obligated by law or executive order to close, then, at each place of payment, such payment need not be made on such day but may be made on the next succeeding day that is not, in the City of New York or at such other place of payment, a day on which banking institutions are authorized or obligated by law or executive order to close, with the same force and effect as if made on the date for such payment, and no interest will accrue for the period from and after such date.

To the extent lawful, the Issuer shall pay interest on any (i) overdue principal of this Note, at the interest rate borne on this Note and (ii) Defaulted Interest (without regard to any applicable grace period), at the same rate. The Issuer's obligation pursuant to the previous sentence shall apply whether such overdue amount is due at its Stated Maturity, as a result of the Issuer's obligations pursuant to Clause 3.4 of the Indenture or otherwise.

3      Method of Payment

The Issuer, through any Paying Agent, shall pay interest on this Note to the registered Holder of this Note, as provided above. The Holder must surrender this Note to a Paying Agent to collect principal payments. The Issuer will pay principal and interest in money of the United States of America that at the time of payment is legal tender for payment of all debts public and private. Interest on this Note shall be paid to the registered Holder hereof at its registered address by U.S. dollar check drawn on a bank in The City of New York or, for Holders of at least U.S.$1,000,000 of Notes, by wire transfer to a U.S. dollar account maintained by the payee with a bank in The City of New York or in Europe, provided that a written request from the Holder to such effect designating such account is received by the Trustee or a Paying Agent no later than the Record Date. Unless such designation is revoked, any such designation made by such Person with respect to this Note will remain in effect with respect to any future payments with respect to this Note payable to such person. The Issuer will pay any administrative costs imposed by banks in connection with making payments by wire transfer.

4      Paying Agent and Registrar

Initially, the Trustee will act as Paying Agent and Registrar and J.P. Morgan Bank Luxembourg S.A. will act as the Luxembourg Paying Agent under the Indenture. The Issuer may, upon written notice to the Trustee, appoint and change any Paying Agent or Registrar. Neither the Issuer, the Guarantor nor any Affiliate of the Issuer or the Guarantor may act as Registrar or Paying Agent with respect to this Note or the Notes generally.

5      Guarantee

This Note is entitled to the benefits of the Guarantee made for the benefit of the Holders of the Notes pursuant to Clause 10 of the Indenture. The Guarantor has irrevocably and unconditionally guaranteed to each Holder and to the Trustee on behalf of the Holders (i) the due and punctual payment of principal of and interest in full on the Notes when and as the same shall become due and payable whether at Stated Maturity, by declaration of acceleration, redemption or otherwise and the due and punctual payment of all other sums stated in the Indenture and the Notes to be payable pursuant to the Indenture and the Notes, including, without limitation, any Additional Amounts; (ii) the due and punctual payment of interest on the overdue principal of and interest in full on the Notes, to the extent permitted by law; and (iii) the due and punctual performance of all other duties, agreements, covenants and obligations of the Issuer to the Holders or the Trustee, including without limitation the payment of fees, expenses, indemnification or other amounts, all in accordance with the terms of the Notes and the Indenture. The Guarantor has also agreed to pay any and all expenses (including reasonable fees and expenses of counsel) incurred by the Trustee or the Holders in enforcing any rights under the Guarantee, and has further agreed to indemnify

Holders and the Trustee against all documentary, stamp or other similar taxes payable in connection with the execution, delivery or enforcement of the Guarantee.

6      Additional Amounts

All payments by the Issuer in respect of this Note and the Indenture and by the Guarantor in respect of the Guarantee and the Indenture will be made free and clear of and without deduction or withholding for or on account of any present or future taxes, duties, assessments, fees or other governmental charges ("Taxes") imposed or levied by or on behalf of Luxembourg, the Russian Federation, any jurisdiction from or through which a payment is made, or any political subdivision or taxing authority thereof or therein (each, a "Taxing Jurisdiction"), unless such withholding or deduction is required by law. If the Issuer is required to make any withholding or deduction for or on account of any Taxes from any payment made under or with respect to this Note, or if the Guarantor is required to make any withholding or deduction for or on account of any Taxes imposed by a Taxing Jurisdiction from any payment made under or with respect to the Guarantee, the Issuer (or, in respect of the Guarantee, the Guarantor) will pay as additional interest to the Holder of this Note such additional amounts (the "Additional Amounts") as may be necessary in order that every net payment made by the Issuer on this Note or by the Guarantor on the Guarantee after deduction or withholding for or on account of any Taxes will not be less than the amount then due and payable on this Note or the Guarantee. The foregoing obligation to pay Additional Amounts, however, will not apply to any (i) Taxes that would not have been imposed but for the existence of any present or former connection between the Holder of this Note and any Taxing Jurisdiction other than the mere receipt of such payment or the ownership or holding of this Note; (ii) Taxes that would not have been imposed but for the presentation by the Holder of this Note for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later; (iii) Taxes required to be deducted or withheld by any Paying Agent from a payment on this Note or the Guarantee, if such payment can be made without deduction or withholding by any other Paying Agent; (iv) Taxes that would not have been imposed but for the failure of the Holder to comply with the Issuer's written request addressed to the Holder at least 60 days prior to the relevant payment to provide information with respect to any reasonable certification, documentation, information or other reporting requirement concerning the nationality, residence, identity or connection with the Taxing Jurisdiction of the Holder of such Note; (v) Taxes imposed on a payment to an individual that are required to be made pursuant to European Union Directive 2003/48/EC or any other European Union Directive implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000 on the taxation of savings income or any law implementing or complying with, or introduced in order to conform to, such Directive; or (vi) estate, inheritance, gift, sale or excise tax.

7      Redemption for Tax Reasons

This Note may be redeemed at the option of the Issuer in whole, but not in part, at any time, on giving not less than 30 nor more than 60 days' notice in accordance with Clause 3 of the Indenture at the principal amount hereof, together with any Additional Amounts and interest accrued to the date fixed for redemption, if (a) the Issuer or the Guarantor has or will become obligated to pay Additional Amounts as described in Clause 6 of this Note and in Clause 4.11 of the Indenture as a result of any change in, or amendment to, the laws, treaties, rulings or regulations of any Taxing Jurisdiction, or any change in, or amendment to the application or official interpretation of such laws, treaties, rulings or regulations, including a holding by a court of competent jurisdiction, which change or amendment becomes effective on or after 28 January 2005 (or in the case of Additional Amounts that a successor to the Guarantor or the Issuer is obligated to pay, the date on which that successor became such pursuant to the Indenture); provided that in the case of Additional Amounts payable by the Guarantor arising from an imposition or levy of Taxes by the Russian Federation or any political subdivision or taxing authority thereof on amounts paid under the Guarantee, the Taxes are imposed or levied at a rate in excess of 30 per cent. on the gross amount

payable under the Guarantee, and (b) such obligation cannot be avoided by the Issuer or the Guarantor taking reasonable measures available to it; provided that no such notice of redemption shall be given earlier than 60 days prior to the earliest date on which the Issuer or the Guarantor would be obliged to pay such Additional Amounts were a payment in respect of this Note then due. Prior to the publication of any notice of redemption pursuant to this paragraph, the Issuer shall deliver to the Trustee an Officer's Certificate stating that the Issuer is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Issuer so to redeem have occurred, and an Opinion of Counsel of recognized international standing to the effect that the Issuer has or will become obligated to pay such Additional Amounts as a result of such change or amendment.

This Note may be redeemed pursuant to this Clause only if all Notes are simultaneously so redeemed.

If money in an amount sufficient to pay the Redemption Price of all Notes to be redeemed on the Redemption Date pursuant to this Clause 7 is deposited with a Paying Agent on or before the applicable Redemption Date and certain other conditions are satisfied, interest on the Notes to be redeemed on the applicable Redemption Date will cease to accrue.

8      Redemption upon a Change in Control

If a Change in Control occurs, the Holder of this Note will have the right to require the Issuer to redeem it at a Redemption Price equal to 101 per cent. of the principal amount hereof plus accrued interest.

Within 30 days after the occurrence of a Change in Control, the Issuer will deliver to the Holders, the Trustee and the Luxembourg Paying Agent notice of the Change in Control and of the resulting redemption right. Upon receipt by the Trustee or the Luxembourg Paying Agent (for so long as the Notes are listed on the Luxembourg Stock Exchange) from a Holder, on or before the 30^th day after the date of the Issuer's notice referred to in the previous sentence, of (a) a properly completed notice in the form specified by the Indenture and (b) this Note, the Issuer will redeem this Note no earlier than 30 and no later than 60 days after the date of the Issuer's notice of the Change in Control.

The Holder of this Note may not exercise its right to require the Issuer to redeem it pursuant to this Clause 8 in the event the Issuer has already exercised its option to redeem this Note in accordance with Clause 7 hereof.

9      The Global Note

So long as this Global Note is registered in the name of the [Rule 144A Note: Depositary] [RegS Note: Common Depositary] or a nominee or successor thereof, members of, or account holders or participants in (the "Agent Members") the [Rule 144A Note: Depositary] [RegS Note: Common Depositary] shall have no rights under the Indenture with respect to this Global Note held on their behalf by the [Rule 144A Note: Depositary][RegS Note: Common Depositary] or the Trustee as its custodian, and the [Rule 144A Note: Depositary][RegS Note: Common Depositary] may be treated by the Issuer, the Guarantor, the Trustee and any agent of the Issuer, the Guarantor or the Trustee as the absolute owner of this Global Note for all purposes. Notwithstanding the foregoing, nothing herein shall (i) prevent the Issuer, the Guarantor, the Trustee or any agent of the Issuer, the Guarantor or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the [Rule 144A Note: Depositary] [RegS Note: Common Depositary] or (ii) impair, as between the [Rule 144A Note: Depositary] [RegS Note: Common Depositary] and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of a beneficial interest in the Notes.

The Holder of this Global Note may grant proxies and otherwise authorize any Person, including Agent Members of the [Rule 144A Note: Depositary] [RegS Note: Common Depositary] and

Persons that may hold interests in this Global Note through such Agent Members, to take any action which a Holder of Notes is entitled to take under the Indenture or the Notes.

Whenever, as a result of an exchange for Certificated Notes, this Global Note is redeemed, repurchased or exchanged in part, this Global Note shall be surrendered by the Holder thereof to the Trustee who shall cause an adjustment to be made to Schedule A hereof so that the principal amount of this Global Note will be equal to the portion not redeemed, repurchased or exchanged and the Trustee shall thereafter return this Global Note to such Holder; provided that this Global Note shall be in a principal amount of $2,000 or integral multiples thereof.

10    Transfer and Exchange

A Holder may transfer or exchange Notes as provided in the Indenture and subject to certain limitations therein set forth. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes, fees and expenses required by law or permitted by the Indenture.

11    Denominations

The Notes are issuable only in fully registered form without coupons in minimum denominations of $2,000 and integral multiples thereof.

12    Unclaimed Money

Any funds paid by the Issuer to the Trustee or any Paying Agent in trust for the payment of the principal, interest or Additional Amounts on this Note that remains unclaimed for two years after the date upon which such payment shall have become due, shall be promptly repaid to the Issuer without interest upon receipt by the Trustee of an Order to that effect; provided, however, that the Issuer shall cause to be published at least once in a newspaper of general circulation in The City of New York and in Europe or mailed to the Holder of this Note entitled to such unclaimed funds, notice that such funds remain unclaimed and that, after a date specified therein, which shall be a date not less than 30 days from the date of such publication or mailing, any unclaimed balance of such money remaining as of such date shall be repaid to the Issuer without interest. Holders shall not be entitled to receive interest on such unclaimed funds under any circumstances. After repayment to the Issuer, the Holder of this Note entitled to such unclaimed funds shall look only to the Issuer for payment without interest thereon, as an unsecured general creditor, and the Issuer shall not be liable to pay any taxes or other duties in connection with any such payment. The Trustee and the Paying Agent, subject to applicable law, shall have no further liability with respect to any such money repaid to the Issuer, and the Issuer shall not be a trustee in respect of such funds. Notwithstanding any other provision of this Clause and unless otherwise provided by applicable law, the right to receive payment of principal of this Note (whether at maturity, redemption or otherwise) will become void at the end of 10 years from the relevant date thereof (or such shorter period as may be prescribed by applicable law).

Subject to certain exceptions set forth in the Indenture, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding, and any existing Default and its consequences may be waived with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder of Notes, the Issuer, the Guarantor and the Trustee may amend the Indenture or the Notes: (i) to evidence the succession of another Person to the Issuer or the Guarantor and the assumption by such successor of the covenants of the Issuer and the Guarantor under the Indenture and contained in the Notes; (ii) to add additional covenants or to surrender rights and powers conferred on the Issuer or Guarantor; (iii) to add any additional Events of Default; (iv) to

Subject to certain limitations, Holders of a majority in principal amount of the Notes then outstanding may direct the Trustee in its exercise of any trust or power under the Indenture. The Holders of a majority in principal amount of the Notes then outstanding, by written notice to the Issuer, the Guarantor and the Trustee may rescind any declaration of acceleration and its consequences if certain conditions are met, as more fully set forth in the Indenture. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

15    Individual Rights of Trustee

Subject to certain limitations imposed by the Trust Indenture Act, the Trustee or any Paying Agent or Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer, the Guarantor or their Affiliates with the same rights it would have if it were not Trustee, Paying Agent or Registrar, as the case may be, under the Indenture.

16    No Recourse Against Certain Others

No director, officer, employee, incorporator or stockholder of the Issuer or the Guarantor, as such, shall have any liability for any obligations of the Issuer or the Guarantor under the Notes, the Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation, solely by reason of its status as a director, officer, employee, incorporator or stockholder of the Issuer or the Guarantor, as the case may be. By accepting a Note, each Holder waives and releases all such liability (but only such liability) as part of the consideration for issuance of such Note to such Holder.

17    Reports

The Guarantor shall (i) file within the Commission and furnish to the Trustee, within 180 days of the end of each fiscal year, an annual report on Form 20-F (or any successor form) containing the information required to be contained therein (or in such successor form, regardless of whether the Guarantor is then required to file a Form 20-F under the rules promulgated by the Commission, (ii) make public and furnish to the Trustee, within 120 days of the end of each fiscal year, reports for the fourth quarter of such fiscal year containing its consolidated balance sheet, statement of operations and cash flow statement prepared in accordance with U.S. GAAP (but excluding footnotes) and a discussion by its management highlighting critical financial developments during the fourth quarter; and (iii) submit to the Commission or otherwise make public and furnish to the Trustee, within 60 days of the end of the first three fiscal quarters of each fiscal year, quarterly reports on Form 6-K (or any successor form) containing its consolidated balance sheet, statement of operations and cash flow statement prepared in accordance with U.S. GAAP (but excluding footnotes) and a discussion by its management highlighting critical financial developments during the period.

from such reporting requirements pursuant to and in compliance with Rule 12g3-2(b) under the Exchange Act, it will provide to each Holder of the Notes (or holder of a beneficial interest therein) and to each prospective purchaser of the Notes (as designated by such Holder or holder of a beneficial interest), upon the request of such Holder, prospective purchaser or holder of a beneficial interest, any information required to be provided by Rule 144A(d)(4) under the Securities Act.
