5.4Prepayment upon Change of Control Put   Event

5.4.1Promptly, and in any event within 30 calendar days after becoming aware of the occurrence of any Change of Control Put Event, the Borrower shall deliver to the Lender and the Trustee a written notice in the form of an Officers’ Certificate, which notice shall be irrevocable, stating that a Change of Control Put Event has occurred and stating the circumstances and relevant facts giving rise to such Change of Control Put Event.

Upon any such cancellation by or on behalf of the Registrar, the principal amount of

the Loan corresponding to the principal amount of such Notes shall be extinguished for all purposes as of the date of such cancellation.

5.6Payment of Other Amounts

If the Loan is to be prepaid by the Borrower pursuant to any of the provisions of Clause 5.2, 5.3 or 5.4, the Borrower shall, simultaneously with such prepayment, pay to the Lender accrued interest thereon to the date of actual payment and all other sums payable by the Borrower pursuant to this Agreement in relation to the prepaid amount. For the avoidance of doubt, if the principal amount of the Loan is reduced pursuant to the provisions of Clause 5.5, then no interest shall accrue or be payable during the Interest Period in which such reduction takes place in respect of the amount by which the Loan is so reduced and the Lender shall not be entitled to any interest in respect of the cancelled  Notes.

All payments of principal, interest and additional amounts (other than those in respect of Reserved Rights) to be made by the Borrower under this Agreement shall be made unconditionally by credit transfer to the Lender not later than 10 a.m. (New York City time) one Business Day prior to each Interest Payment Date or the Repayment Date or the date of any payment (as the case may be) in Same-Day Funds to the Account, or as the Trustee may otherwise direct following the occurrence of a Default or a Relevant Event.

The Borrower shall, before 10 a.m. (Local Time) on the second Business Day prior to each Interest Payment Date or the Repayment Date or such other date (as the case may be), procure that the bank effecting such payments on its behalf confirms to the Principal Paying Agent or to the Borrower (who shall immediately provide the same to the Principal Paying Agent) by authenticated SWIFT the payment instructions relating to such payment.

The Lender agrees with the Borrower that it will not deposit any other moneys into the Account and that no withdrawals shall be made from the Account other than as provided for and in accordance with the Trust Deed and the Agency Agreement.

The parties to the Trust Deed and the Agency Agreement are intended by the parties to this Agreement to have the right under the Contracts (Rights of Third Parties) Act 1999 to enforce the terms of this Clause 6.1.

6.2No Set-Off, Counterclaim or Withholding;  Gross-Up

All payments to be made by the Borrower under this Agreement shall be made in full without set-off or counterclaim and (except to the extent required by law) free and clear of and without deduction for or on account of any Taxes. If the Borrower shall be required by applicable law to make any deduction or withholding from any payment under this Agreement for or on account of any such Taxes, it shall, on the due date for such payment, increase the payment of principal or interest or any other payment due hereunder to such amount as may be necessary to ensure that the Lender receives a net amount in U.S. Dollars equal to the full amount which it would have received had payment not been made subject to such Taxes, and shall promptly account to the relevant authorities for the relevant amount of such Taxes so withheld or deducted within the time allowed for such payment under applicable law, and shall deliver to the Lender without undue delay evidence of such deduction or withholding and of the accounting therefor to the relevant taxing authority. If the Lender pays any amount in respect of such Taxes (including penalties or interest)

the Borrower shall reimburse the Lender in U.S. Dollars for such properly documented payment on demand. For the avoidance of doubt, this Clause 6.2 is without prejudice to any obligations of the Lender contained in Clause 6.6.

6.3Withholding on the  Notes

Without prejudice to the provisions of Clause 6.2, if the Lender notifies the Borrower (setting out in reasonable detail the nature and extent of the obligation) that it has become obliged to make any withholding or deduction for or on account of any present or future taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or on behalf of Ireland or any political subdivision or any authority thereof or therein having the power to tax from any payment which it is obliged to make, or would otherwise be obliged to make but for the imposition of any such withholding or deduction for or on account of such taxes, under or in respect of the Notes, the Borrower agrees to pay into the Account in Same-Day Funds, no later than one Business Day prior to the date on which payment is due to the Noteholders, such additional amounts as are equal to the additional amounts which the Lender would be required to pay in order that the net amounts received by the Noteholders, after such withholding or deduction, will equal the respective amounts which would have been received by the Noteholders in the absence of such withholding or deduction; provided, however, that the Lender shall immediately upon receipt from any Paying Agent of any reimbursement of the sums paid pursuant to this provision, to the extent that any Noteholders are not entitled to such additional amounts pursuant to the Conditions, pay such additional amounts to the Borrower (it being understood that neither the Lender, the Principal Paying Agent or any Paying Agent shall have any obligation to determine whether any Noteholder is entitled to any such additional amounts).

Any notification by the Lender to the Borrower in connection with this Clause 6.3 shall be given as soon as reasonably practicable after the Lender becomes aware of any obligation on it to make any such withholding or deduction.

6.4Reimbursement

To the extent that the Lender subsequently obtains or uses any tax credit or allowance or other reimbursements relating to a deduction or withholding with respect to which the Borrower has made a payment pursuant to this Clause 6, the Lender shall promptly pay to the Borrower so much of the benefit it received as will leave the Lender in substantially the same position as it would have been had no additional amount been required to be paid by the Borrower pursuant to this Clause 6; provided, however, that the question of whether any such benefit has been received, and accordingly, whether any payment should be made to the Borrower, the amount of any such payment and the timing of any such payment, shall be determined reasonably by the Lender. Subject to Clauses 6.5 and 6.6, the Lender shall have the absolute discretion whether, and in what order and manner, it claims any credits, allowances or refunds available to it, and the Lender shall in no circumstances be obliged to disclose to the Borrower any information regarding its tax affairs or its computations.

6.5Mitigation

If at any time either party hereto becomes aware of circumstances which would or might, then or thereafter, give rise to an obligation on the part of the Borrower to make any deduction, withholding or payment as described in Clauses 6.2 or 6.3, then, without in any way limiting, reducing or otherwise qualifying the Lender’s rights, or the Borrower’s obligations, under such Clauses, such party shall as soon as reasonably practicable upon becoming aware of such circumstances notify the other party, and, thereupon the parties shall consider and consult with each other in good faith with a view to finding, agreeing upon and implementing a method or methods by which any such obligation may be avoided or mitigated and, to the extent that both parties can do so without taking any action which in the reasonable opinion of such party is prejudicial to its own position, take such reasonable steps as may be available to it to avoid such obligation or mitigate the effect of such circumstances. The Borrower agrees to reimburse the Lender upon receipt of an original demand for payment for all properly documented costs and

expenses (including but not limited to legal fees) incurred by the Lender in connection with this Clause 6.5.

6.6Tax Treaty Relief

6.6.1The Lender shall once in each calendar year, prior to the first Interest Payment Date in that calendar year, at the expense of the Borrower, use commercially reasonable efforts to obtain and deliver, to the Borrower no later than 10 Business Days prior to such Interest Payment Date, a tax residency certificate issued by the competent authorities of Ireland confirming that the Lender is resident for tax purposes in Ireland. At the cost of the Borrower, the residency certificate shall be apostilled at the Irish Department of Foreign Affairs. Provided that the tax residency certificate application has been filed in due time, the Lender shall not be responsible for any failure to provide, or any delays in providing, such tax residency certificate as a result of any action or inaction of any authority of Ireland, but shall notify the Borrower as soon as practicable about any such failure or delay with an indication of the actions taken by the Lender to obtain such tax residency certificate.

6.6.2If Russian legislation regulating the procedures for obtaining an exemption from Russian withholding tax on income changes, the Lender shall (subject to being informed of any such changes by the Borrower) use its reasonable and timely efforts to assist the Borrower to obtain relief from such tax pursuant to the double taxation treaty between the Russian Federation and Ireland and the procedures referred to in Clause 6.6.1 will be deemed changed accordingly.

7.CONDITIONS PRECEDENT

The obligation of the Lender to make the Advance shall be subject to the further conditions precedent that as at the Closing Date (a) the representations and warranties made and given by the Borrower in Clause 9.1 shall be true and accurate as if made and given on the Closing Date with respect to the facts and circumstances then existing; (b) the Borrower shall not be in breach of any of the terms, conditions and provisions of this Agreement; (c) the Subscription Agreements, the Agency Agreement and the Trust Deed shall have been executed and delivered; (d) the Lender shall have received the full amount of the proceeds of the issue of the Notes pursuant to the Subscription Agreements; and (e) the Lender shall have received in full the amount referred to in Clause  2.3.

8.1.3imposes or will impose on the Lender any other condition affecting this Agreement, the Facility or the Loan,

(ii)the amount of principal, interest or additional amounts payable to or received by the Lender hereunder is reduced; or

(iii)the Lender makes any payment or foregoes any interest or other return on or calculated by reference to the gross amount of any sum receivable by it from the Borrower hereunder or makes any payment or foregoes any interest or other return on or calculated by reference to the gross amount of the Loan,

provided that this Clause 8.1 will not apply to or in respect of any matter for which the Lender has already been compensated under Clauses 6.2 and 6.3.

8.2Mitigation

In the event that the Lender becomes entitled to make a claim pursuant to Clause 8.1, the Lender shall consult in good faith with the Borrower and shall use reasonable efforts (based on the Lender’s reasonable interpretation of any relevant tax, law, regulation, requirement, official directive, request, policy or guideline) to reduce, in whole or in part, the Borrower’s obligations to pay any additional amount pursuant to such Clause except that nothing in this Clause 8.2 shall obligate the Lender to incur any costs or expenses in taking any action hereunder which, in the

reasonable opinion of the Lender, is prejudicial to it unless the Borrower agrees to reimburse the Lender such costs or expenses.

If the

amount in the first currency that may be so purchased for any reason falls short of the amount originally due (the ‘‘Due Amount’’), the Borrower hereby agrees to indemnify and hold harmless the Lender against any deficiency in the first currency.

14.3Waivers

No failure to exercise and no delay in exercising, on the part of the Lender or the Borrower, any right, power or privilege hereunder and no course of dealing between the Borrower and the Lender shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege preclude any other or further exercise thereof, or the exercise of any other right, power or privilege.
