(a) to cooperate with the Requesting Party in good faith with a view to effect a joint offering of Equity Securities by Sistema and the Five Percent Offering by TMO with each party undertaking to refrain from effecting any Prohibited Transactions during the period commencing on the date of pricing of such joint offering and ending on the later of (i) 1 October 2003, and, if applicable, (ii) the date of pricing of any Five Percent Offering and/or Ten Percent Offering (the “Lock-up Period”) without prejudice to Section 7.3.4; or

(b) not to pursue a joint offering of Equity Securities with the Requesting Party and undertake to the Requesting Party that it will not (nor will any of its Affiliates or agents on its behalf) effect any Prohibited Transactions at any time during the Lock-up Period.

If the Notified Party fails to make a timely election, it shall be deemed to have made an election under Section 7.3.2(b). Furthermore, if despite a party’s election under Section 7.3.2(a), such party subsequently does not participate in

such offering, such party shall nonetheless refrain from effecting any Prohibited Transactions during the Lock-Up Period.

7.3.3 For the avoidance of doubt, nothing in this Section 7.3 shall limit TMO’s ability to prepare the Five Percent Offering and/or the Ten Percent Offering during the period commencing 15 August 2003 in accordance with Section 2.4 of this Agreement.

7.3.4 Sistema agrees and undertakes to TMO that it will not (nor will any of its Affiliates) at any time within the period commencing on 1 October 2003 and ending on the earlier of (a) the date falling 90 calendar days after the date of pricing of any Five Percent Offering or Ten Percent Offering, as the case may be, and (b) 31 March 2004 effect any Prohibited Transactions, provided that this Section 7.3.4 shall not apply where TMO shall elect to exercise its rights pursuant to Section 2.5.2(b).

7.3.5 Each Party undertakes to use all reasonable efforts to procure that for a period of 90 calendar days (a) following the pricing date of any offering by Sistema of Equity Securities, and (b) following the date of pricing of the Five Percent Offering, MTS and the directors and executive officers of MTS will not effect any Prohibited Transactions, other than transactions with Equity Securities in connection with duly exercised options under management stock option plans of MTS.

7.3.6 None of the undertakings or obligations set out in this Section 7.3 shall, for the avoidance of doubt, prevent the Parties from preparing and implementing concurrently with, prior to, or after the Five Percent Offering a listing and offering of MTS Shares on a registered Russian stock exchange (“Local Listing”); provided that (a) the Parties shall at all times consult with each other in good faith as to (i) the possibility of avoiding, but if necessary, the implementation of, such Local Listing pursuant to this Section 7.3.6, and (ii) the ability for the Local Listing to be undertaken concurrently with or after the Five Percent Offering in accordance with this Section 7.3, if so desired by TMO, (b) any Equity Securities which are the subject of the Local Listing shall be targeted for distribution to the Russian domestic market, provided that in the event that sufficient demand (including demand sourced from third parties) cannot be generated in order to comply with the applicable listing and trading liquidity rules and regulations of the FCSM and the relevant Russian stock exchange, TMO may also solicit international demand in the form of a private placement and (c) TMO may offer in the Local Listing, at its sole discretion, the minimum number of MTS shares required in order to comply with the applicable listing

and trading liquidity rules and regulations of the FCSM and the relevant Russian stock exchange which, in any event, shall not exceed the equivalent of 500,000 ADSs. Notwithstanding the provisions of this Section 7.3.6, a higher amount may mutually be agreed in writing by the parties as necessary to satisfy the requirements of the FCSM and relevant Russian stock exchange.

For the purposes of this Section 7.3:

“Equity Securities” shall mean MTS Shares, or any depositary shares or receipts issued on such ordinary shares, or

securities exchangeable or convertible into MTS Shares or any depositary shares or receipts issued on such ordinary shares.

“Prohibited Transactions” shall mean to:

(i) offer, pledge, issue, sell, contract to sell, sell any option or contract to purchase, purchase any option to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of (or seek or solicit any such transfer or disposal), directly or indirectly, any Equity Securities other than to an Affiliate, or

(ii) enter into any swap, hedge or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of any Equity Securities;

whether any such transaction described in (i) or (ii) above is to be settled by delivery of such Equity Securities or such other securities, in cash or otherwise provided, however, that Prohibited Transactions shall not include any pledges of MTS Shares underlying any Sistema Debt Financing which pledges comply with the terms set forth in Annex 7.3.

8. REMEDIES FOR BREACHES OF THIS AGREEMENT

8.1 Survival of Warranties

All the representations and warranties of the Parties contained in this Agreement shall survive Completion (even if the Party alleging to have suffered a loss knew or had reason to know of any breach of representation or warranty at the time of Completion) and shall continue in full force and effect for a period of two (2) years from the Transfer Date or Earlier Transfer Date (as the case may be).

Time shall be of the essence of this Agreement, both as regards the dates and periods mentioned and as regards any dates and periods which may be substituted for them by agreement in writing between the Parties.

11.10 Third Party Beneficiaries

This Agreement shall not confer any rights or remedies on any other Person other than the Parties and their respective successors and permitted assigns. For the avoidance of doubt, a Person who is not a Party to this Agreement has no right under the English Contracts (Rights of Third Parties) ▇▇▇ ▇▇▇▇ to enforce any term of this Agreement.

11.11 Amendments and Waivers

No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by each of TMO, Smaragd and Sistema. No waiver by any Party of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. No failure to exercise and no delay in exercising any right, power or remedy under this Agreement will operate as a waiver; nor will

any single or partial exercise of any right, power or remedy preclude any other or further exercise of that or any other right, power or remedy.

11.12 Severance

In the event any provision of this Agreement or any provision incorporated herein in the future is or becomes invalid in whole or in part, the validity of the other provisions shall not be affected thereby. To replace any invalid provision, that reasonable provision shall apply which, as permitted by law, most closely approximates that which the Parties desired. In the event the invalidity of any provision is based on any scope of performance or time (deadline or period) determined therein, that scope of performance or time (deadline or period) shall be considered as agreed upon which, as permitted by law, most closely approximates the provision.

11.13 Construction

The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favouring or disfavouring any Party by virtue of the authorship of any of the provisions of this Agreement. Any reference to any national, supranational, federal, state, local, or foreign statute or law shall be deemed also to refer to any successor entity and all rules and regulations promulgated thereunder, unless the context requires otherwise. The word “including” shall mean including without limitation. The Parties intend that each representation, warranty, and covenant contained herein shall have independent significance. If any Party has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty, or covenant relating to the same subject matter (regardless of the relative levels of specificity) which the Party has not breached shall not detract from or mitigate the fact that the Party is in breach of the first representation, warranty, or covenant.

11.14 Expenses

Section 12.12 of the Shareholders’ Agreement shall be applicable with regard to any costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby irrespective of whether the Shareholders’ Agreement shall be in force at such time.

11.15 Taxes and Transaction Expenses

11.15.1 Each Party shall be responsible for their respective Taxes and fees (including any penalties and interest) incurred in connection with this Agreement. Any such Taxes and fees shall be paid by such Party responsible for such Taxes when due, and such Party will, at its own expense, file all necessary tax returns and other documentation with respect to all such Taxes and fees, as required by applicable law.

11.15.2 Subject only to Section 11.15.3 below, Sistema shall bear all fees and Taxes to be paid in connection with the execution and implementation and Completion of the Call Option, in particular any expenses incurred in connection with the clearance by the MAP and any fees to be paid to the registrar of MTS or ISH (as applicable) in connection with the transfer of the Underlying Shares or ISH Shares (if applicable) from TMO and Smaragd (if applicable) to Sistema.

11.15.3 Withholding Tax on the Purchase Price

(a) In the event that at any time during the Call Option Period and, where the Call Option shall have been exercised, prior to the remittance of the Purchase Price in accordance with Section 5.1 Sistema (or a designated Affiliate of Sistema) intends, due to amended or newly introduced Tax laws or regulations applicable in the Russian Federation, to deduct withholding tax from the Purchase Price, Sistema (or a designated Affiliate of Sistema) shall immediately inform TMO and Smaragd in writing in accordance with Section 11.7.1 (“Notice on Changed Tax Circumstances”). In such case, the Parties undertake to immediately enter into good faith negotiations with each other in order to seek agreement upon the most appropriate means to avoid a payment of withholding tax by Sistema (or a designated Affiliate of Sistema). During such negotiations, the Parties shall (i) fully cooperate with and consult each other and with tax authorities if appropriate, and, (ii) where agreement shall be achieved between the Parties, support and, at the cost of TMO, implement all reasonable actions and measures in connection therewith and (iii) to the extent legally permissible, neither withhold any potential tax amount nor make any payments to tax authorities for as long as all actions necessary to implement such agreement have been taken.

(b) In the event that the Parties do not reach an agreement during such good faith negotiations, and in any event within 20 (twenty) Business Days following service of the Notice on Changed Tax Circumstances by Sistema (or a designated Affiliate of Sistema) on TMO, then, in the absence of delivery by TMO to Sistema at least 5 (five) Business Days

prior to the Earlier Transfer Date or Transfer Date (as the case may be) of an original, duly executed certificate of residence or other appropriate certificate as required by Tax laws and documenting exemption from all requirements relating to any such obligation of Sistema (or a designated Affiliate of Sistema) to apply withholding tax issued by the appropriate taxation authorities, payment by Sistema to TMO of the Purchase Price in accordance with Section 5.1 shall be made net of applicable withholding tax.

(c) In the event that the Notice on Changed Tax Circumstances will be served later than 20 Business Days prior to the Transfer Date or the Earlier Transfer Date (as the case may be), the Parties agree that such Transfer Date or Earlier Transfer Date (as the case may be) shall be delayed to such date falling 20 Business Days following the date of serving the Notice on Changed Tax Circumstances. The implementation of the provision in this Section 11.15.3 (c) shall not, for the avoidance of doubt, constitute grounds for termination by TMO and Smaragd pursuant to Section 10.2. hereof or otherwise under this Agreement.

11.16 Incorporation of Exhibits, Annexes and Schedules

The exhibits, annexes and schedules identified in this Agreement are incorporated herein by reference and made a part hereof.

11.17 Specific Performance

Each of the Parties acknowledges and agrees that the other Parties would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached. Accordingly, each of the Parties agrees that the other Parties shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in any action instituted in any court having jurisdiction over the Parties and the matter, in addition to any other remedy to which they may be entitled, at law or in equity.

The tribunal shall be comprised of three arbitrators to be appointed in accordance with the Rules. The language of the arbitration shall be English. Judgment upon any arbitral award may be entered in any court of competent jurisdiction. Court jurisdiction under Sections 45 and 69 of the United Kingdom’s Arbitration Act of 1996 shall not apply. For the purposes of this Section 11.19, (including for the appointment of arbitrators in accordance with the Rules) TMO and Smaragd shall (where Section 2.2.2 shall be applicable) be considered one party and for all purposes herunder service on, or notification to, TMO shall be good and valid service on, or notification to, Smaragd.
