representing

ORDINARY SHARES

MOBILE TELESYSTEMS OJSC

(Incorporated under
the laws of the Russian Federation)

JPMORGAN CHASE BANK, a New York corporation, as depositary hereunder (the "Depositary"), hereby certifies that is the registered owner (a "Holder") of American Depositary Shares ("ADSs"), each (subject to paragraph (14)) representing twenty shares of common stock (including the rights to receive Shares described in paragraph (1), "Shares" and, together with any other securities, cash or property from time to time held by the Depositary in respect or in lieu of deposited Shares, the "Deposited Securities"), of MOBILE TELESYSTEMS OJSC, a corporation organized under the laws of the Russian Federation (the "Company"), deposited at the Moscow, Russian Federation office of ING Bank (Eurasia) ZAO, as Custodian (subject to paragraph (16), the "Custodian"), under the Deposit Agreement dated as of July 6, 2000 (as amended from time to time, the "Deposit Agreement") among the Company, the Depositary and all Holders from time to time of American Depositary Receipts issued thereunder ("ADRs"), each of whom by accepting an ADR

A-1

becomes a party thereto. The Deposit Agreement and this ADR (which includes provisions set forth on the reverse hereof) shall be governed by and construed in accordance with the laws of the State of New York, except with respect to its authorization and execution by the Company, which shall be governed by the laws of the Russian Federation.

(1) Issuance of ADRs. This ADR is one of the ADRs issued under the Deposit Agreement. Subject to paragraph (4), the Depositary may so issue ADRs for delivery at the Transfer Office (defined in paragraph (3)) only against deposit with the Custodian of: (a) Shares in form satisfactory to the Custodian; (b) rights to receive Shares from the Company or any registrar, transfer agent, clearing agent or other entity recording Share ownership or transactions; or, (c) other rights to receive Shares (until such Shares are actually deposited pursuant to (a) or (b) above, "Pre-released ADRs") only if (i) Pre-released ADRs are fully collateralized (marked to market daily) with cash or U.S. government securities held by the Depositary for the benefit of Holders (but such collateral shall not constitute "Deposited Securities"), (ii) each recipient of Pre-released ADRs agrees in writing with the Depositary that such recipient (a) owns such Shares, (b) assigns all beneficial right, title and interest therein to the Depositary, (c) holds such Shares for the account of the Depositary and (d) will deliver such Shares to the Custodian as soon as practicable and promptly upon demand therefor and (iii) all Pre-released ADRs evidence not more than 30% of all ADSs (excluding those evidenced by Pre-released ADRs), provided, however, that the Depositary reserves the right to change or disregard such limit from time to time as it reasonably deems appropriate. The Depositary may retain for its own account any earnings on collateral for Pre-released ADRs and its charges for issuance thereof. At the request, risk and expense of the person depositing Shares, the Depositary may accept deposits for forwarding to the Custodian and may deliver ADRs at a place other than its office. Every person depositing Shares under the Deposit Agreement represents and warrants that such Shares are validly issued and outstanding, fully paid, nonassessable and free of pre-emptive rights, that the person making such deposit is duly authorized so to do and that such Shares (A) are not "restricted securities" as such term is defined in Rule 144 under the Securities Act of 1933 unless at the time of deposit they may be freely transferred in accordance with Rule 144(k) and may otherwise be offered and sold freely in the United States or (B) have been registered under the Securities Act of 1933. Such representations and warranties shall survive the deposit of Shares and issuance of ADRs. The Depositary will not knowingly accept for deposit under the Deposit Agreement any Shares required to be registered under the Securities Act of 1933 and not so registered; the Depositary may refuse to accept for such deposit any Shares identified by the Company in order to facilitate the Company's compliance with such Act.

(2) Withdrawal of Deposited Securities. Subject to paragraphs (4) and (5), upon surrender of (i) a certificated ADR in form satisfactory to the Depositary at the Transfer Office or (ii) proper instructions and documentation in the case of a Direct Registration ADR, the Holder hereof is entitled to delivery at the Custodian's office of the Deposited Securities at the time represented by the ADSs evidenced by this ADR. At the request, risk and expense of the Holder hereof, the Depositary may deliver such Deposited Securities at such other place as may have been requested by the Holder. Notwithstanding any other provision of the Deposit Agreement or this ADR, the withdrawal of Deposited Securities may be restricted only for the reasons set forth in General Instruction I.A.(1) of Form F-6 (as such instructions may be amended from time to time) under the Securities Act of 1933.

(3) Transfers of ADRs. The Depositary or its agent will keep, at a designated transfer office in the Borough of Manhattan, The City of New York (the "Transfer Office"), (a) a register (the "ADR Register") for the registration, registration of transfer, combination and split-up of ADRs, and, in the case of Direct Registration ADRs, shall include the Direct Registration System, which at all reasonable times will be open for inspection by Holders and the Company for the purpose of communicating with Holders in the interest of the business of the Company or a matter relating to the Deposit Agreement and (b) facilities for the delivery and receipt of ADRs. The term ADR Register includes the Direct Registration System. Title to this ADR (and to the Deposited Securities represented by the ADSs

A-2

evidenced hereby), when properly endorsed (in the case of ADRs in certificated form) or upon delivery to the Depositary of proper instruments of transfer, is transferable by delivery with the same effect as in the case of negotiable instruments under the laws of the State of New York; provided that the Depositary, notwithstanding any notice to the contrary, may treat the person in whose name this ADR is registered on the ADR Register as the absolute owner hereof for all purposes. Subject to paragraphs (4) and (5), this ADR is transferable on the ADR Register and may be split into other ADRs or combined with other ADRs into one ADR, evidencing the same number of ADSs evidenced by this ADR, by the Holder hereof or by duly authorized attorney upon surrender of this ADR at the Transfer Office properly endorsed (in the case of ADRs in certificated form) or upon delivery to the Depositary of proper instruments of transfer and duly stamped as may be required by applicable law; provided that the Depositary may close the ADR Register at any time or from time to time when reasonably deemed expedient by it or requested by the Company. At the request of a Holder, the Depositary shall, for the purpose of substituting a certificated ADR with a Direct Registration ADR, or vice versa, execute and deliver a certificated ADR or a Direct Registration ADR, as the case may be, for any authorized number of ADSs requested, evidencing the same aggregate number of ADSs as those evidenced by the certificated ADR or Direct Registration ADR, as the case may be, substituted.

(4) Certain Limitations. Prior to the issue, registration, registration of transfer, split-up or combination of any ADR, the delivery of any distribution in respect thereof, or, subject to the last sentence of paragraph (2), the withdrawal of any Deposited Securities, and from time to time in the case of clause (b)(ii) of this paragraph (4), the Company, the Depositary or the Custodian may require: (a) payment with respect thereto of (i) any stock transfer or other tax or other governmental charge, (ii) any stock transfer or registration fees in effect for the registration of transfers of Shares or other Deposited Securities upon any applicable register and (iii) any applicable charges as provided in paragraph (7) of this ADR; (b) the production of proof satisfactory to it of (i) the identity and genuineness of any signature and (ii) such other information, including without limitation, information as to citizenship, residence, exchange control approval, beneficial ownership of any securities, compliance with applicable law, regulations, provisions of or governing Deposited Securities and terms of the Deposit Agreement and this ADR, as it may deem necessary or proper; and (c) compliance with such regulations as the Depositary may establish consistent with the Deposit Agreement. The issuance of ADRs, the acceptance of deposits of Shares, the registration, registration of transfer, split-up or combination of ADRs or, subject to the last sentence of paragraph (2), the withdrawal of Deposited Securities may be suspended, generally or in particular instances, when the ADR Register or any register for Deposited Securities is closed or when any such action is deemed advisable by the Depositary or the Company.

(5) Taxes. If any tax or other governmental charge shall become payable by or on behalf of the Custodian or the Depositary with respect to this ADR, any Deposited Securities represented by the ADSs evidenced hereby or any distribution thereon, such tax or other governmental charge shall be paid by the Holder hereof to the Depositary. The Depositary may refuse to effect any registration, registration of transfer, split-up or combination hereof or, subject to the last sentence of paragraph (2), any withdrawal of such Deposited Securities until such payment is made. The Depositary also may deduct from any distributions on or in respect of Deposited Securities, or may sell by public or private sale for the account of the Holder hereof any part or all of such Deposited Securities (after attempting by reasonable means to notify the Holder hereof prior to such sale), and may apply such deduction or the proceeds of any such sale in payment of such tax or other governmental charge, the Holder hereof remaining liable for any deficiency, and shall reduce the number of ADSs evidenced hereby to reflect any such sales of Shares. In connection with any distribution to Holders, the Company will remit to the appropriate governmental authority or agency all amounts (if any) required to be withheld and owing to such authority or agency by the Company; and the Depositary and the Custodian will remit to the appropriate governmental authority or agency all amounts (if any) required to be withheld and owing to such authority or agency by the Depositary or the Custodian. If the Depositary determines that any

A-3

distribution in property other than cash (including Shares or rights) on Deposited Securities is subject to any tax that the Depositary or the Custodian is obligated to withhold, the Depositary may dispose of all or a portion of such property in such amounts and in such manner as the Depositary deems reasonably necessary and practicable to pay such taxes, by public or private sale, and the Depositary shall distribute the net proceeds of any such sale or the balance of any such property after deduction of such taxes to the Holders entitled thereto.

(6) Disclosure of Interests. To the extent that the provisions of or governing any Deposited Securities (including the Company's Charter or applicable law) may require disclosure of or impose limits on beneficial or other ownership of Deposited Securities, other Shares and other securities and may provide for blocking, transfer, voting or other rights to enforce such disclosure or limits, Holders and all persons holding ADRs agree to comply with all such disclosure requirements and ownership limitations and to cooperate with the Depositary in the Depositary's compliance with any Company instructions in respect thereof, and the Depositary will use reasonable efforts to comply with such Company instructions.

(7) Charges of Depositary. The Depositary may charge each person to whom ADRs are issued against deposits of Shares, including deposits in respect of Share Distributions, Rights and Other Distributions (as such terms are defined in paragraph (11)), and each person surrendering ADRs for withdrawal of Deposited Securities (including, without limitation, on the termination of the Deposit Agreement), U.S. $5.00 for each 100 ADSs (or portion thereof) evidenced by the ADRs delivered or surrendered. The Depositary may sell (by public or private sale) sufficient securities and property received in respect of Share Distributions, Rights and Other Distributions prior to such deposit to pay such charge. The Company will pay all other charges and expenses of the Depositary and any agent of the Depositary (except the Custodian) pursuant to agreements from time to time between the Company and the Depositary, except (i) stock transfer or other taxes and other governmental charges (which are payable by Holders or persons depositing Shares), (ii) cable, telex and facsimile transmission and delivery charges incurred at the request of persons depositing, or Holders delivering Shares, ADRs or Deposited Securities (which are payable by such persons or Holders), (iii) transfer or registration fees for the registration of transfer of Deposited Securities on any applicable register in connection with the deposit or withdrawal of Deposited Securities (which are payable by persons depositing Shares or Holders withdrawing Deposited Securities; there are no such fees in respect of the Shares as of the date of the Deposit Agreement), (iv) expenses of the Depositary in connection with the conversion of foreign currency into U.S. dollars (which are paid out of such foreign currency) and (v) a fee of $0.01 or less per ADS (or portion thereof) per year to cover such expenses as are incurred for inspections by the Depositary, the Custodian or their respective agents of the Share Register maintained by the Russian Share Registrar (which fee shall be assessed against Holders of record as of the date set by the Depositary in accordance with paragraph (12) hereof not more often than once each calendar year). These charges may be changed in the manner indicated in paragraph (17).

(8) Depositary's Agents. The Depositary may perform its obligations under this Deposit Agreement through any agent appointed by it, provided that the Depositary shall notify the Company of such appointment and shall remain responsible for the performance of such obligations as if no such agent were appointed. With respect to any and all losses, damages, costs, judgments, expenses and other liabilities (including reasonable attorneys' fees and expenses) (collectively referred to as "Losses") incurred by any Holder or Beneficial Owner as a result of the acts or failure to act by such agent or attorney (or, in the case of the Custodian, only such damages as are described below), the Depositary shall take appropriate action to recover such Losses from such agent or attorney and as promptly as practicable shall distribute any amounts so recovered (exclusive of costs and expenses incurred by the Depositary in connection with recovering such Losses which are not reimbursed by such agent or attorney, including, without limitation, the Custodian) to the Holders and Beneficial Owners entitled thereto; and the Depositary's sole responsibility and liability to such Holders and Beneficial Owners

A-4

shall be limited to amounts so received from such agent or attorney (exclusive of costs and expenses incurred by the Depositary in connection with recovering such Losses which are not reimbursed by such agent or attorney, including, without limitation, the Custodian).

The liability of the Custodian is set forth in the Custody Agreement between the Depositary and the Custodian (the "Custody Agreement"). Under the terms of the Custodian Operating Agreement, the Custodian is only liable for its breach of the Custody Agreement, its negligence, willful default or fraud in connection with the performance of its obligations thereunder and for loss of Shares or funds held in custody under the Custody Agreement. In each case, the liability of the Custodian with respect to the loss of Shares or funds will be limited to direct (but not indirect, including consequential) losses incurred by Holders and Beneficial Owners.

Moreover, only the Depositary, acting on behalf of Holders and Beneficial Owners, will be permitted to bring claims against the Custodian in respect of such losses incurred by Holders and Beneficial Owners as a result of the acts of, or the failure to act by, the Custodian. Any such claims by the Depositary against the Custodian will be resolved exclusively by arbitration. The Depositary agrees to promptly remit to Holders any amounts recovered from such claims (exclusive of costs and expenses incurred by the Depositary in connection with recovering such losses which are not reimbursed by the Custodian). The Depositary shall have no other responsibility or liability to Holders or Beneficial Owners with respect to the acts of, or the failure to act by, the Custodian or for the unavailability of the Shares or the failure to make any distribution of cash or property with respect thereto as a result of such unavailability.

The liability of the Custodian for such losses incurred by Holders and Beneficial Owners, the obligation of the Depositary to bring claims against the Custodian for such losses and the method by which such claims may be brought are subject to the terms and conditions of the Custody Agreement, a copy of which is available from the Depositary upon the written request of any Holder.

(9) Available Information. The Deposit Agreement, the provisions of or governing Deposited Securities and any written communications from the Company, which are both received by the Custodian or its nominee as a holder of Deposited Securities and made generally available to the holders of Deposited Securities, are available for inspection by Holders at the offices of the Depositary and the Custodian and at the Transfer Office. The Depositary will mail copies of such communications (or English translations or summaries thereof) to Holders when furnished by the Company.

The Company is subject to the periodic reporting requirements of the Securities Exchange Act of 1934 and accordingly files certain reports with the U.S. Securities and Exchange Commission (the "Commission").

(c) Rights. (i) Warrants or other instruments in the discretion of the Depositary representing rights to acquire additional ADRs in respect of any rights to subscribe for additional Shares or rights of any nature available to the Depositary as a result of a distribution on Deposited Securities ("Rights"), to the extent that the Company timely furnishes to the Depositary evidence satisfactory to the Depositary that the Depositary may lawfully distribute the same (the Company has no obligation to so furnish such evidence), or (ii) to the extent the Company does not so furnish such evidence and sales of Rights are practicable, any U.S. dollars available to the Depositary from the net proceeds of sales of Rights as in the case of Cash, or (iii) to the extent the Company does not so furnish such evidence and such sales cannot practicably be accomplished by reason of the nontransferability of the Rights, limited markets therefor, their short duration or otherwise, nothing (and any Rights may lapse).

Such U.S. dollars available will be distributed by checks drawn on a bank in the United States for whole dollars and cents (any fractional cents being withheld without liability for interest and added to future Cash distributions).

(12) Record Dates. The Depositary, after consultation with the Company if practicable, may fix a record date (which shall be as near as practicable to any corresponding record date set by the Company) for the determination of the Holders who shall be entitled to receive any distribution on or in respect of Deposited Securities, to give instructions for the exercise of any voting rights, for the determination of the Holders who shall be responsible for the fee assessed by the Depositary for inspection of the Share Register maintained by the Russian Share Registrar, to receive any notice or to act in respect of other matters and only such Holders shall be so entitled.

The Depositary may resign as Depositary by written notice of its election to do so delivered to the Company, or be removed as Depositary by the Company by written notice of such removal delivered to the Depositary. The Depositary may appoint substitute or additional Custodians and the term "Custodian" refers to each Custodian or all Custodians as the context requires.

(17) Amendment. Subject to the last sentence of paragraph (2), the ADRs and the Deposit Agreement may be amended by the Company and the Depositary, provided that any amendment that imposes or increases any fees or charges (other than stock transfer or other taxes and other governmental charges, transfer or registration fees, cable, telex or facsimile transmission costs, delivery costs or other such expenses), or that shall otherwise prejudice any substantial existing right of Holders, shall become effective 30 days after notice of such amendment shall have been given to the Holders. Every Holder of an ADR at the time any amendment to the Deposit Agreement so becomes effective shall be deemed, by continuing to hold such ADR, to consent and agree to such amendment and to be bound by the Deposit Agreement as amended thereby. In no event shall any amendment impair the right of the Holder of any ADR to surrender such ADR and receive the Deposited Securities represented thereby, except in order to comply with mandatory provisions of applicable law. Any amendments or supplements which (i) are reasonably necessary (as agreed by the Company and the Depositary) in order for (a) the ADSs to be registered on Form F-6 under the Securities Act of 1933

A-8

or (b) the ADSs or Shares to be traded solely in electronic book-entry form and (ii) do not in either such case impose or increase any fees or charges to be borne by Holders, shall be deemed not to prejudice any substantial rights of Holders. Notwithstanding the foregoing, if any governmental body should adopt new laws, rules or regulations which would require amendment or supplement of the Deposit Agreement or the form of ADR to ensure compliance therewith, the Company and the Depositary may amend or supplement the Deposit Agreement and the ADR at any time in accordance with such changed rules. Such amendment or supplement to the Deposit Agreement in such circumstances may become effective before a notice of such amendment or supplement is given to Holders or within any other period of time as required for compliance.

(18) Termination. Upon the resignation or removal of the Depositary pursuant to the Deposit Agreement, the Depositary may, and shall at the written direction of the Company, terminate the Deposit Agreement and this ADR by mailing notice of such termination to the Holders at least 30 days prior to the date fixed in such notice for such termination. After the date so fixed for termination, the Depositary and its agents will perform no further acts under the Deposit Agreement and this ADR, except to receive and hold (or sell) distributions on Deposited Securities and deliver Deposited Securities being withdrawn. As soon as practicable after the expiration of six months from the date so fixed for termination, the Depositary shall sell the Deposited Securities and shall thereafter (as long as it may lawfully do so) hold in a segregated account the net proceeds of such sales, together with any other cash then held by it under the Deposit Agreement, without liability for interest, in trust for the pro rata benefit of the Holders of ADRs not theretofore surrendered. After making such sale, the Depositary shall be discharged from all obligations in respect of the Deposit Agreement and this ADR, except to account for such net proceeds and other cash. After the date so fixed for termination, the Company shall be discharged from all obligations under the Deposit Agreement except for its obligations to the Depositary and its agents.

(19) Arbitration; Waiver of Immunities. The Deposit Agreement provides that any controversy, claim or cause of action brought by any party to the Deposit Agreement against the Company arising out of or relating to the Shares or other Deposited Securities, the ADSs, the ADRs or the Deposit Agreement, or the breach thereof, shall be referred to, and finally settled by, arbitration in accordance with the Arbitration Rules of the London Court of International Arbitration (the LCIA Rules) in effect on the date of this Agreement, which Rules are deemed incorporated by reference into this paragraph, and that judgment upon the award rendered by the arbitrators may be entered in any court having jurisdiction thereof; provided, that in the event of any third-party litigation to which the Depositary is a party and to which the Company may properly be joined, the Company may be so joined in any court in which such litigation is proceeding; and provided further that any such controversy, claim or cause of action that relates to or is based upon the provisions of the federal securities laws of the United States or the rules and regulations promulgated thereunder may, but need not, be submitted to arbitration as provided in the Deposit Agreement. The Deposit Agreement further provides that any controversy, claim or cause of action arising out of or relating to the Shares or other Deposited Securities, the ADSs, the ADRs or the Deposit Agreement not subject to arbitration shall be litigated in the federal and state courts in the Borough of Manhattan. The Company has agreed in the Deposit Agreement to appoint Xxxxxxx & Associates, presently having its office at 000 Xxxxxxx Xxxxxx, Xxxxx 000, Xxxxxx, Xxxxxxxx 00000, Xxxxxx Xxxxxx of America, as its agent for service of process.

To the extent that the Company or any of its properties, assets or revenues may have or hereafter become entitled to, or have attributed to it, any right of immunity, or the grounds of sovereignty or otherwise, from any legal action, suit or proceeding, from the giving of any relief in any respect thereof, from setoff or counterclaim, from the jurisdiction of any court, from service of process, from attachment upon or prior to judgment, from attachment in aid of execution or judgment, or other legal process or proceeding or the giving of any relief or for the enforcement of any judgment, in any jurisdiction in which proceedings may at any time be commenced, with respect to its obligations,

A-9

liabilities or any other matter under or arising out of or in connection with the Shares or Deposited Securities, the ADSs, the ADRs or the Deposit Agreement, the Company, to the fullest extent permitted by law, hereby irrevocably and unconditionally waives, and agrees not to plead or claim, any such immunity and consents to such relief and enforcement.

(i): take any and all action as may be necessary to assure the accuracy and completeness of all information set forth in the Share Register maintained by the Russian Share Registrar in respect of the Shares or Deposited Securities;
(ii): provide or use its best efforts to cause the Russian Share Registrar to provide to the Depositary, the Custodian or their respective agents unrestricted access to the Share Register during ordinary business hours in Moscow, the Russian Federation, in such manner and upon such terms and conditions as the Depositary, in its reasonable discretion, may deem appropriate, to permit the Depositary, the Custodian or their respective agents to regularly (and in any event not less than monthly) confirm the number of Deposited Securities registered in the name of the Depositary, the Custodian or their respective nominees, as applicable, pursuant to the terms of this Deposit Agreement and, in connection therewith, to provide the Depositary, the Custodian or their respective agents, upon request, with a duplicate extract from the Share Register duly certified by the Russian Share Registrar (or some other evidence of verification which the Depositary, in its reasonable discretion, deems sufficient);
(iii): use its best efforts to cause the Russian Share Registrar promptly (and, in any event, within 72 hours of the Russian Share Registrar's receipt of such documentation as may be required by applicable law and the reasonable and customary regulations of the Russian Share Registrar, or as soon as practicable thereafter to effect the reregistration of ownership of Deposited Securities in the Share Register in connection with any deposit or withdrawal of Shares or Deposited Securities under the Deposit Agreement;
(iv): permit and use its best efforts to cause the Russian Share Registrar to permit the Depositary or the Custodian to register any Shares or other Deposited Securities held under the Deposit Agreement in the name of the Depositary, the Custodian or their respective nominees (which may, but need not be, a non-resident of the Russian Federation); and
(v): use its best efforts to cause the Russian Share Registrar promptly to notify the Depositary in writing at any time that the Russian Share Registrar (A) eliminates the name of a shareholder of the Company from the Share Register or otherwise alters a shareholder's interest in the Company's shares and such shareholder alleges to the Company or the Russian Share Registrar or publicly that such elimination or alteration is unlawful; (B) no longer will be able materially to comply with, or has engaged in conduct that indicates it will not materially comply with, the provisions of this Deposit Agreement relating to it (including, without limitation, Section 19); (C) refuses to re-register shares of the Company in the name of a particular purchaser and such purchaser (or its respective seller) alleges that such refusal is unlawful; (D) holds Shares of the Company for its own account; or (E) has materially breached the provisions of the Deposit Agreement relating to it (including, without limitation, Section 19) and has failed to cure such breach within a reasonable time.

(b) The Company has agreed in the Deposit Agreement that it shall be solely liable for any act or failure to act on the part of the Russian Share Registrar, and that the Company shall be solely liable for the unavailability of Deposited Securities or for the failure of the Depositary to make any distribution of cash or property with respect thereto as a result of (i) any act or failure to act of the

A-10

Company or its agents, including the Russian Share Registrar, or their respective directors, employees, agents or affiliates, (ii) any provision of any present or future Charter of the Company or any other instrument of the Company governing the Deposited Securities, or (iii) any provision of any securities issued or distributed by the Company, or any offering or distribution thereof.

(c) The Depositary has agreed in the Deposit Agreement that the Depositary or the Custodian will confirm regularly (and in any event not less than monthly) the number of Deposited Securities registered in the name of the Depositary, the Custodian or their respective nominees, as applicable, pursuant to the terms of the Deposit Agreement. The Company and the Depositary have agreed in the Deposit Agreement that, for the purposes of the rights and obligations under the Deposit Agreement and this ADR of the parties thereto and hereto, the records of the Depositary and the Custodian shall be controlling for all purposes with respect to the number of Shares or other Deposited Securities which should be registered in the name of the Depositary, the Custodian or their respective nominees, as applicable, pursuant to the terms of the Deposit Agreement. In the event of any material discrepancy between the records of the Depositary or the Custodian and the Share Register, then, if the Depositary has knowledge of such discrepancy, the Depositary will notify the Company promptly. In the event of any discrepancy between the records of the Depositary or the Custodian and the Share Register, the Company has agreed that (whether or not it has received any notification from the Depositary) it will use its best efforts to (i) cause the Russian Share Registrar to reconcile its records to the records of the Depositary or the Custodian and to make such corrections or revisions in the Share Register as may be necessary in connection therewith and (ii) to the extent the Company is unable to so reconcile such records, promptly instruct the Depositary to notify the Holders of the existence of such discrepancy. Upon receipt of such instruction, the Depositary promptly will give such notification to the Holders (it being understood that the Depositary may at any time give such notification to the Owners, whether or not it has received instructions from the Company) and will promptly cease issuing ADRs pursuant to the Deposit Agreement until such time as, in the opinion of the Depositary, such records have been appropriately reconciled.
