13

4. INTEREST PERIODS

The period for which the Loan is outstanding shall be divided into successive semi-annual periods, ending on and excluding 22 October and 22 April, each of which, other than the first (which shall commence on, and shall include, 22 October 2004) shall start on, and shall include, the last day of the preceding such period (each, an “Interest Period”).

5. PAYMENT AND CALCULATION OF INTEREST

5.1 Payment of Interest

Not later than noon (London time) one Business Day prior to each Interest Payment Date the Borrower shall pay all accrued and unpaid interest, any Additional Amounts, and any Tax Indemnity Amounts, calculated to the last day of each Interest Period, on the outstanding principal amount of the Loan to the Account.

5.2 Calculation of Interest

The amount of interest payable for any Interest Period shall be calculated by applying the rate of 8.375% per annum (the “Interest Rate”) to the amount of the Loan, dividing the product by two, and rounding the resulting figure to the nearest cent, half a cent being rounded upwards. When interest is required to be calculated for any other period, it shall be calculated on the basis of a 360 day year consisting of 12 months of 30 days each, and in the case of an incomplete month, the actual number of days elapsed.

6. REPAYMENT

Subject to Clause 15.2 (Rights of Lender upon occurrence of an Event of Default), not later than noon (London time) one Business Day prior to the Repayment Date, the Borrower shall repay in full the outstanding principal amount of the Loan and, to the extent not already paid in accordance with Clause 5.1 (Payment of Interest), all accrued and unpaid interest, any Additional Amounts, and any Tax Indemnity Amounts, calculated to (but excluding) the last day of the last Interest Period.

7. PREPAYMENT

7.1 Prepayment for Tax Reasons

If, as a result of the application of or any amendment to or change (including a change in interpretation or application) in the double taxation treaty between Russia and Luxembourg (or any Qualifying Jurisdiction in which the Lender or any successor thereto is resident for tax purposes) or the laws or regulations of Russia or Luxembourg (or any Qualifying Jurisdiction in which the Lender or any successor thereto is resident for tax purposes) or of any political sub-division thereof or any Agency therein, or as a result of the Lender ceasing to be resident in Luxembourg or a Qualifying Jurisdiction by reason of any Change of Law (including a change in the double taxation treaty or in such law or treaty’s application or interpretation), the Borrower would thereby be required to pay any Additional Amounts in respect of Taxes pursuant to Clause 8.1 (Additional Amounts), or pay any Tax Indemnity Amounts pursuant to Clause 8.3 (Tax Indemnity), then the Borrower may (without premium or penalty), upon not less than 30 calendar days’ written notice to the Lender (and, following the execution of the agreements entered into in connection with the agreed funding source, to the party designated by such agreements) including an Officers’ Certificate of the Borrower, to the effect that the Borrower would be required to pay such Additional Amounts or Tax Indemnity Amounts, which notice shall be irrevocable, prepay the Loan in whole (but not in part) at any time together with all accrued and unpaid interest, any Additional Amounts and any Tax Indemnity

14

Amounts; provided, however, that no such notice shall be given earlier than 90 calendar days prior to the earliest date on which the Borrower would be obligated to pay such Additional Amounts or Tax Indemnity Amounts, as the case may be.

7.2 Prepayment for Reasons of Increased Costs

The Borrower may (without premium or penalty), if it is required to make any payment by way of indemnity under Clause 10.1 (Increased Costs), subject to giving to the Lender not less than 30 calendar days’ prior written notice to that effect, prepay the whole, but not part only, of the amount of the Loan, together with any amounts then payable under Clause 10.1 (Increased Costs) and accrued and unpaid interest, any Additional Amounts and Tax Indemnity Amounts, if any.

7.3 Notice of Prepayment

Without prejudice to any other requirement in this Agreement, any notice of prepayment given by the Borrower pursuant to Clause 7.1 (Prepayment for Tax Reasons) or Clause 7.2 (Prepayment for Reasons of Increased Costs) hereof, shall be irrevocable, shall specify the date upon which such prepayment is to be made and shall oblige the Borrower to make such prepayment one Business Day prior to such date.

7.4 Costs of Prepayment

The Borrower shall, on the date of prepayment, pay all accrued and unpaid interest, any Additional Amounts and any Tax Indemnity Amounts (each only with respect to the amount subject to such prepayment), as of such date of prepayment and all other amounts payable to the Lender hereunder in connection with such prepayment. The Borrower shall indemnify the Lender on demand against any costs and expenses reasonably Incurred and properly documented by the Lender on account of any prepayment made in accordance with this Clause 7 (Prepayment).

7.5 No Other Repayments

The Borrower shall not repay the whole or any part of the amount of the Loan except at the times and in the manner expressly provided for in this Agreement.

7.6 Purchase of Instruments Issued to the Agreed Funding Source

The Borrower and its Subsidiaries may purchase any instruments issued to the agreed funding source at any time in the open market or otherwise. If such instruments are surrendered by the Borrower or any of its Subsidiaries to the Lender, as issuer of such instruments, for cancellation (together with an authorisation addressed to the agent of the agreed funding source to cancel such instruments), the Lender shall, against any such surrender and cancellation, credit the Borrower with the prepayment on the date(s) of such surrender and cancellation by an amount equal to the principal amount of such cancelled instruments. Any such amount of the loan prepaid shall reduce the outstanding principal amount of the loan by the same amount and interest shall cease to accrue on such prepaid amount with effect from and including the date of such prepayment. The Lender and its subsidiaries may purchase any instruments issued to the agreed funding source at any time in the open market or otherwise. In the event that such purchase by the Lender or any of its subsidiaries is financed by the Borrower for the purpose of reducing, in part or in full, the principal amount of the loan outstanding, the Lender or such subsidiary shall, upon purchase of such instruments, (i) authorise the agent of the agreed funding source to cancel such instruments and (ii) credit the Borrower with the prepayment on the date(s) of such surrender and cancellation by an amount equal to the principal amount of such cancelled instruments. Any such amount of the loan

15

prepaid shall reduce the outstanding principal amount of the loan by the same amount and interest shall cease to accrue on such prepaid amount with effect from and including the date of such prepayment.

8. TAXES

8.1 Additional Amounts

(a) Subject to Clause 8.1(b), all payments made by the Borrower under or with respect to the Loan will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment, or other governmental charge (including penalties, interest and other liabilities related thereto) (collectively, “Taxes”) imposed or levied by or on behalf of any government or political subdivision or territory or possession of any government or authority or Agency therein or thereof having the power to tax (each, a “Taxing Authority”) within Russia or Luxembourg (or any Qualifying Jurisdiction in which the Lender or any successor thereto is resident for tax purposes), unless the Borrower is required to withhold or deduct Taxes by law or by the interpretation or administration thereof. For the avoidance of doubt, this Clause 8.1 shall not apply to any Taxes on income payable by the Lender in Luxembourg (or any Qualifying Jurisdiction).

(b) If at any time the Borrower is required to withhold or deduct any amount for or on account of Taxes imposed or levied by or on behalf of any Taxing Authority within Russia or Luxembourg (or any Qualifying Jurisdiction in which the Lender or any successor thereto is resident for tax purposes) from any payment made under or with respect to the Loan, the Borrower shall, on the due date for such payment, pay such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by the Lender (including Additional Amounts) in U.S. dollars after such withholding or deduction will not be less than the amount the Lender would have received if such Taxes had not been withheld or deducted and free from liability in respect of such withholding or deduction; provided, however, that for the avoidance of doubt, such Additional Amounts shall not be payable with respect to any Taxes on income payable by the Lender in Luxembourg (or any Qualifying Jurisdiction).

(c) The Borrower will also:

(i) make such withholding or deduction; and

(ii) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law.

(d) At least 30 calendar days prior to each date on which any payment under or with respect to the Loan is due and payable, if the Borrower will be obligated to pay Additional Amounts with respect to such payment (upon written notice by the Lender or an agent of the agreed funding source), the Borrower will deliver to the Lender (and, following the execution of the agreements entered into in connection with the agreed funding source, to the party designated by such agreements) an Officers’ Certificate stating the fact that such Additional Amounts will be payable and the amounts so payable and will set forth such other information necessary to enable the Lender (and, following the execution of any other agreements entered into in connection with the agreed funding source, the party designated by such agreements) to pay such Additional Amounts to or for the account of the agreed funding source on the relevant payment date.

16

(e) If the Lender pays any amount in respect of such Taxes, the Borrower shall reimburse the Lender in U.S. dollars for such payment on demand.

(f) Whenever this Agreement mentions, in any context, the payment of amounts based upon the principal, interest or of any other amount payable under or with respect to any of the Loan, this includes, without duplication, payment of any Additional Amounts and Tax Indemnity Amounts that may be applicable.

The foregoing provisions shall apply, modified as necessary, to any Taxes imposed or levied by any Taxing Authority in any jurisdiction in which any successor obligor to the Borrower is organised.

8.2 Payments

The Borrower shall assist the Lender in ensuring that all payments made under this Agreement are exempt from deduction or withholding of Tax.

8.3 Tax Indemnity

Without prejudice to, and without duplication of, the provisions of Clause 8.1 (Additional Amounts),

(a) if at any time the Lender makes or is required to make any payment to a Person (other than to or for the account of the agreed funding source) on account of Tax (other than Taxes on income payable by the Lender in Luxembourg or any Qualifying Jurisdiction) in respect of the Loan or in respect of any instruments issued to, or documents entered into with, the agreed funding source imposed by any Taxing Authority of or in Russia, Luxembourg or any Qualifying Jurisdiction in which the Lender or any successor thereto is resident for tax purposes, or any liability in respect of any such payment is asserted, imposed, levied or assessed against the Lender, the Borrower shall, as soon as reasonably practicable following, and in any event within 30 calendar days of, written demand made by the Lender, indemnify the Lender against such payment or liability, together with any interest, penalties, costs and expenses payable or Incurred in connection therewith; and

(b) if at any time a Taxing Authority imposes an obligation on the Lender to withhold or deduct any amount on any payment made or to be made by the Lender to or for the account of the agreed funding source and the Lender is required by any instruments issued to, or documents entered into with, the agreed funding source, to pay additional amounts to such agreed funding source in connection therewith, the Borrower shall, as soon as reasonably practicable following, and in any event within 30 calendar days of, written demand made by the Lender, pay to the Lender such additional amounts as may be necessary so that the net amount received by the agreed funding source (including such additional amounts) in U.S. dollars after such withholding or deduction will not be less than the amount such agreed funding source would have received if such withholdings or deductions had not been made and free from liability in respect of such withholding or deduction.

Any payments required to be made by the Borrower under this Clause 8.3 are collectively referred to as “Tax Indemnity Amounts”. For the avoidance of doubt, the provisions of this Clause 8.3 shall not apply to any withholding or deductions of Taxes with respect to the Loan which are subject to payment of Additional Amounts under Clause 8.1.

17

8.4 Tax Claims

If the Lender intends to make a claim for any Tax Indemnity Amounts pursuant to Clause 8.3 (Tax Indemnity), it shall notify the Borrower thereof; provided that nothing herein shall require the Lender to disclose any confidential information relating to the organisation of its affairs.

8.5 Tax Credits and Tax Refunds

(a) If any Additional Amounts are paid under Clause 8.1 (Additional Amounts) or Tax Indemnity Amounts are paid under Clause 8.3 (Tax Indemnity) by the Borrower for the benefit of the Lender and the Lender, in its reasonable opinion, determines that it has received or been granted a credit against, a relief or remission for, or a repayment of, any Tax, then, if and to the extent that the Lender, in its reasonable opinion, determines that such credit, relief, remission or repayment is in respect of or calculated with reference to the deduction or withholding giving rise to such Additional Amounts or, in the case of Tax Indemnity Amounts, with reference to the liability, expense or loss to which the payment giving rise to such Tax Indemnity Amounts relates, the Lender shall, to the extent that it can do so without prejudice to the retention of the amount of such credit, relief, remission or repayment, pay to the Borrower such amount as the Lender shall, in its reasonable opinion, have concluded to be attributable to such deduction or withholding or, as the case may be, such liability, expense or loss; provided that the Lender shall not be obliged to make any payment under this Clause 8.5 in respect of such credit, relief, remission or repayment until the Lender is, in its reasonable opinion, satisfied that its tax affairs for its tax year in respect of which such credit, relief, remission or repayment was obtained have been finally settled. Any such payment shall, in the absence of manifest error and subject to the Lender specifying in writing in reasonable detail the calculation of such credit, relief, remission or prepayment and of such payment and providing relevant supporting documents evidencing such matters, be conclusive evidence of the amount due to the Borrower hereunder and shall be accepted by the Borrower in full and final settlement of its rights of reimbursement hereunder in respect of such deduction or withholding. Nothing contained in this Clause 8.5 shall interfere with the right of the Lender to arrange its tax affairs generally in whatever manner it thinks fit nor oblige the Lender to disclose any information relating to its tax affairs generally or any computations in respect thereof.

(b) If as a result of a failure to obtain relief from deduction or withholding of any Tax imposed by Russia or Luxembourg (or any Qualified Jurisdiction in which the Lender or any successor thereto is resident for tax purposes) (i) such Tax is deducted or withheld by the Borrower and pursuant to Clause 8.1 (Additional Amounts) an increased amount is paid by the Borrower to the Lender in respect of such deduction or withholding, and (ii) following the deduction or withholding of Tax as referred to above, (A) the Borrower applies on behalf of the Lender to the relevant Russian Taxing Authorities for a tax refund and such tax refund is credited by the Russian Taxing Authorities to the Lender or (B) if such tax refund is otherwise credited by a relevant Taxing Authority to the Lender pursuant to a final decision of such Taxing Authority, the Lender shall as soon as reasonably possible notify the Borrower of the receipt of such tax refund and promptly transfer the entire amount of the tax refund to a bank account of the Borrower specified for that purpose by the Borrower.

8.6 Representations of the Lender

The Lender represents that (a) it is a bank which at the date hereof is a resident of Luxembourg, is subject to taxation in Luxembourg on the basis of its registration as a legal entity, location of its management body or another similar criterion and it is not subject to taxation in Luxembourg merely on income from sources in Luxembourg or connected with

18

property located in Luxembourg; (b) it will account for the Loan on the date of closing on its balance sheet as an asset under “loans and advances to customers” and any arrangements with the agreed funding source as a liability under “liabilities evidenced by paper”; and (c) at the date hereof, it does not have a permanent establishment in Russia.

The Lender shall make reasonable and timely efforts to assist the Borrower to obtain relief from withholding of Russian income tax pursuant to the double taxation treaty between Russia and the jurisdiction in which the Lender is incorporated, including its obligations under Clause 8.8 (Delivery of Forms). The Lender makes no representation as to the application or interpretation of any double taxation treaty between Russia and the jurisdiction in which the Lender is incorporated.

8.7 Exceptions

The Lender agrees promptly, upon becoming aware of such, to notify the Borrower if it ceases to be resident in Luxembourg or a Qualifying Jurisdiction or if any of the representations set forth in Clause 8.6 are no longer true and correct. If the Lender ceases to be resident in Luxembourg or a Qualifying Jurisdiction, then, except in circumstances where the Lender has ceased to be resident in Luxembourg or a Qualifying Jurisdiction by reason of any Change of Law (including a change in a double taxation treaty or in such law or treaty’s application or interpretation), in each case taking effect after the date of this Agreement, the Borrower shall not be liable to pay to the Lender under Clause 8.1 (Additional Amounts) or Clause 8.3 (Tax Indemnity) any sum in excess of the sum it would have been obliged to pay if the Lender had not ceased to be resident in Luxembourg or a Qualifying Jurisdiction.

8.8 Delivery of Forms

The Lender shall within 30 calendar days of the request of the Borrower, to the extent it is able to do so under applicable law including Russian laws, deliver to the Borrower a certificate issued by the competent Taxing Authority in Luxembourg (or any Qualifying Jurisdiction in which the Lender or any successor thereto is resident for tax purposes) confirming that the Lender is a tax resident in Luxembourg (or any Qualifying Jurisdiction in which the Lender or any successor thereto is resident for tax purposes) and such other information or forms as may need to be duly completed and delivered by the Lender to enable the Borrower to apply to obtain relief from deduction or withholding of Russian Tax after the date of this Agreement or, as the case may be, to apply to obtain a tax refund if a relief from deduction or withholding of Russian Tax has not been obtained. The Lender shall, within 30 calendar days of the request of the Borrower, to the extent it is able to do so under applicable law including Russian laws, from time to time deliver to the Borrower any additional duly completed application forms as need to be duly completed and delivered by the Lender to enable the Borrower to apply to obtain relief from deduction or withholding of Russian Tax or, as the case may be, to apply to obtain a tax refund if a relief from deduction or withholding of Russian Tax has not been obtained. The certificate and, if required, other forms referred to in this Clause 8.8 shall be duly signed by the Lender, if applicable, and stamped or otherwise approved by the competent Taxing Authority in Luxembourg (or any Qualifying Jurisdiction in which the Lender or any successor thereto is resident for tax purposes) and apostilled or otherwise legalised. If a relief from deduction or withholding of Russian Tax under this Clause 8.8 has not been obtained and further to an application of the Borrower to the relevant Russian Taxing Authorities the latter requests the Lender’s rouble bank account details, the Lender shall at the request of the Borrower (x) use reasonable efforts to procure that such rouble bank account of the Lender is duly opened and maintained, and (y) thereafter furnish the Borrower with the details of such rouble bank account. The Borrower shall pay for all costs associated, if any, with opening and maintaining such rouble bank account.

19

9. TAX RECEIPTS

9.1 Notification of Requirement to Deduct Tax

If, at any time, the Borrower is required by law to make any deduction or withholding from any sum payable by it hereunder, or if thereafter there is any change in the rates at which or the manner in which such deductions or withholdings are calculated, the Borrower shall promptly notify the Lender.

9.2 Evidence of Payment of Tax

The Borrower will make all reasonable endeavours to obtain certified copies, and translations into English, of tax receipts evidencing the payment of any Taxes so deducted or withheld from each Taxing Authority imposing such Taxes. The Borrower will furnish to the Lender (and, following the execution of any other agreements entered into in connection with the agreed funding source, to the party designated by such agreements), within 60 calendar days after the date the payment of any Taxes so deducted or withheld is due pursuant to applicable law, either certified copies of tax receipts evidencing such payment by the Borrower or, if such receipts are not obtainable, other evidence of such payments by the Borrower.

10. CHANGES IN CIRCUMSTANCES

10.1 Increased Costs

If, by reason of (i) any Change of Law, other than a Change of Law which relates only to the basis or rate of Tax on the net income of the Lender or the amounts required pursuant to the Arrangement Fee Letter, and/or (ii) compliance with any Capital Adequacy Requirement, reserve or deposit requirement or any other request from or requirement of any central bank or other fiscal, monetary or other authority which has effect in Luxembourg (or any Qualifying Jurisdiction in which the Lender or any successor thereto is resident for tax purposes):

(a) the Lender Incurs an additional cost as a result of the Lender’s entering into or performing its obligations, including its obligation to make the Loan, under this Agreement (excluding Taxes payable by the Lender on its overall net income); or

(b) the Lender becomes liable to make any additional payment on account of Tax or otherwise, not being a tax imposed on its net income or the amounts due pursuant to the Arrangement Fee Letter, on or calculated by reference to the amount of the Loan and/or to any sum received or receivable by it hereunder except where compensated under Clause 8.1 (Additional Amounts) or under Clause 8.3 (Tax Indemnity),

then the Borrower shall, from time to time within 30 calendar days of written demand of the Lender, pay to the Lender amounts sufficient to hold harmless and indemnify it from and against, as the case may be, such properly documented (1) cost or (2) liability; provided that the Lender will not be entitled to indemnification where such increased cost or liability arises as a result of the gross negligence, fraud or wilful default of the Lender; and provided that the amount of such increased cost shall be deemed not to exceed an amount equal to the proportion of any cost or liability which is directly attributable to this Agreement.

10.2 Increased Costs Claims

If the Lender intends to make a claim pursuant to Clause 10.1 (Increased Costs), it shall notify the Borrower thereof and provide a written description in reasonable detail of the relevant Change of Law or Capital Adequacy Requirement, as the case may be, including a

20

description of the relevant affected jurisdiction or country and the date on which the change in circumstances took effect; provided that nothing herein shall require the Lender to disclose any confidential information relating to the organisation of its or any other person’s affairs. The written description shall demonstrate the connection between the change in circumstance and the increased costs and shall be accompanied by relevant supporting documentation evidencing the matters described therein.

10.3 Illegality

If, at any time after the date of this Agreement, it is unlawful for the Lender to make, fund or allow to remain outstanding the Loan made or to be made by it hereunder or to maintain its agreed funding source of the Loan then the Lender shall, after becoming aware of the same, deliver to the Borrower a written notice, setting out in reasonable detail the nature and extent of the relevant circumstances, to that effect and:

(a) if the Loan has not then been made, the Lender shall not thereafter be obliged to make the Loan; and

(b) if the Loan is then outstanding and the Lender so requests, the Borrower shall (without premium or penalty), on the latest date permitted by the relevant law or such earlier day as the Borrower elects (as notified to the Lender upon not less than 30 calendar days’ written notice prior to the date of repayment), repay the Loan together with accrued and unpaid interest thereon and all other amounts owing to the Lender hereunder.

10.4 Mitigation

If circumstances arise which would result in:

(a) any payment falling due to be made by or to the Lender or for its account pursuant to Clause 10.3 (Illegality);

(b) any payment falling due to be made by the Borrower pursuant to Clause 8.1 (Additional Amounts); or

(c) a claim for indemnification pursuant to Clause 8.3 (Tax Indemnity) or Clause 10.1 (Increased Costs),

then, without in any way limiting, reducing or otherwise qualifying the rights of the Lender or the Borrower’s obligations under any of the above mentioned provisions, the Lender shall, upon becoming aware of the same, notify the Borrower thereof and, in consultation with the Borrower and to the extent it can lawfully do so and without prejudice to its own position, take reasonable steps to remove such circumstances or mitigate the effects of such circumstances including, without limitation, by the change of its lending office or transfer of its rights or obligations under this Agreement to another bank; provided that the Lender shall be under no obligation to take any such action if, in its opinion, to do so might have any adverse effect upon its business, operations or financial condition or might be in breach of any arrangements which it may have made with the agreed funding source.
