4. Company Car. The Employee will deliver to the Company, and the Company will take possession of, the company car in the Employee’s possession (including all car keys), as soon as practically possible, but in any event, no later than June 15, 2006.

5. Tax Equalization and Assistance In Preparation of Tax Declarations. In accordance with Golden Telecom, Inc.’s Expatriate Tax Protection Policy (“Policy”), and pursuant to relevant laws in the “host country” and “home country”, as defined in the Policy, any estimated federal, state, local, and other taxes owed in the host and home countries by the Company under the Policy will be paid in accordance with this Section.

Within thirty (30) days following the Employee’s Separation Date, the Tax Advisor will determine an estimate of the correct amount of the liability owed by the Company pursuant to the Policy (“Tax Equalization Liability”) for the time period during which the Employee was Employed by the Company (“Employed”). Once the Tax Advisor has determined an estimate of the correct amount of Tax Equalization Liability owed for the time period during which the Employee was Employed by the Company, then the Company or the Employee within thirty (30) days of receiving written notification of such Tax Equalization Liability, will, at the Employee’s option, provide full Tax Equalization Liability reimbursement to the other party or will directly pay the Tax Equalization Liability amounts to the relevant governmental authorities. All payments from the Company pursuant this Agreement and the Policy will be considered “Company Income” under the Policy, and will be subject to applicable protections, payments, reimbursements, and gross-ups under the Policy.

Pursuant to the Policy and in accordance with this Section, the Company will continue to provide professional tax and accounting assistance in the preparation of relevant home and host country tax filings (federal, state, and local) and home and host country tax payments (federal, state, and local), as necessary, for tax years 2005 and 2006 with regard to any and all Company Income and Personal Income earned by the Employee. During the preparation of the 2005 and 2006 home and host country tax filings, if it is determined that the Company has additional Tax Equalization Liability pursuant to the Policy or this Agreement, reimbursements or payments by the Company shall be made in accordance with this Section.

For purposes of this Section, “Employment” or “Employ” includes all time periods the Employee received or will receive compensation from the Company. For purposes of this Section, the “Tax Equalization Liability” calculation by the Tax Advisor will include tax on all payments or reimbursements of all “home country” and “host country” taxes and gross-ups as defined within the Policy. For purposes of this section, “Tax Advisor” as defined here and in the Policy, will be Ernst & Young in the host country and the home country, and the Company will inform the Employee of the relevant tax advisors from Ernst & Young in both the host country and home country.

6. Withholdings; All payments made under this Separation Agreement will be subject to any required tax withholdings subject to Section 5 above.

7. Mutual Release. As a condition to the receipt of the benefits set forth in Section 3 above, the Employee must execute the Mutual Release attached hereto as Exhibit A and such Mutual Release must become irrevocably effective.

8. Non-Disparagement. The Employee will not disparage, portray in a negative light, or take any action which would be harmful to, or lead to unfavorable publicity for, the Company, or any of its current or former officers, directors, employees, agents, consultants, contractors, owners, divisions, parents, subsidiaries, or successors, whether public or private, including without limitation, in any and all interviews, oral statements, written materials, electronically displayed materials, and materials or information displayed on Internet-related sites; provided that this provision will not apply to the extent the Employee is seeking to enforce his rights under this Separation Agreement. The Company will not authorize its current or former officers, directors, employees, agents, consultants, contractors, owners, divisions, subsidiaries or successors to disparage, portray in a negative light, or take any action which would be harmful to, or lead to unfavorable publicity for, the Employee, whether public or private, including without limitation, in any and all interviews, oral statements, written materials, electronically displayed materials, and materials or information displayed on Internet-related sites; provided that this provision will not apply to the extent the Company is seeking to enforce its rights under this Separation Agreement.

9. Non-Disclosure of Information. The Employee affirms that he has not, and will not, without the specific prior written consent of the Company, directly or indirectly, at any time after the date of this Separation Agreement, whether before or after the Separation Date, use on behalf of or divulge to any person or entity, any confidential or proprietary information of the Company or any related company (or any of their clients, suppliers, and vendors) concerning the business, affairs, or clients of the Company or any related company, including without limitation, client lists, customer records, names and addresses, financial documents and statistics, prices, contractual terms and arrangements, surveys and reports, market data, trade secrets, technical data, business or research plans and proposals, or any other information which may have commercial value to the Company, insofar as the same have come to the Employee’s knowledge during or as a result of his employment with the Company, all of which information is confidential and proprietary to the Company and will remain the sole and exclusive property of the Company. However, the Employee will have the right to use the generic knowledge and expertise he acquired during his employment with the Company so as to enable him to be otherwise gainfully employed within the Company’s industry. The Company also expressly acknowledges that the Employee may disclose such information as may be required by law or to comply with legal process, or any such information which is known to the general public or ascertainable from the public or from published information (other than as a result of the Employee’s unauthorized disclosure of such information).

10. Non-Solicitation and Return of Company Property. The Employee will not, for a period of twelve months commencing upon the Separation Date, either alone or with or for others, in whatever capacity, directly or indirectly, without first obtaining the Company’s written approval, (a) solicit, or attempt to solicit, or interfere with any business or services from any customers or clients of the Company or any related company (including without limitation, Golden TeleServices, Inc. and the Company’s affiliated operating companies in Russia, Ukraine, and Kazakhstan), whom the Employee personally served, whose accounts the Employee directly or indirectly supervised, or about whom the Employee was privy to privileged and confidential information, while employed by the Company, or (b) solicit, or attempt to solicit, for employment or any other consulting relationship, any employee holding a management position equal to or above a departmental “Manager” with, or any officer or director of, the Company or any related company (including without limitation, Golden TeleServices, Inc. and the Company’s affiliated operating companies in Russia, Ukraine, and Kazakhstan), who was employed by or provided services to the Company or any related company during the twelve-month period immediately prior to the Separation Date, and without regard to whether such employee, officer, or director continues to be employed by or provide services to the Company or any related company during the twelve-month non-solicitation period.

It is acknowledged and understood that by executing this Separation Agreement, the parties hereto regard the restrictions of this Section 10 to be reasonable and compatible with their respective rights.

To the extent not dealt with elsewhere in this Separation Agreement, the Employee will deliver promptly, but no later than the Separation Date, to the Company (and not keep in his possession or deliver to any other person or entity) any and all property belonging to the Company or any related company, including without limitation, computer hardware and software, palm pilots, pagers, other electronic equipment, credit cards, keys, records, data, notes, reports, correspondence, client files and information, confidential and/or proprietary information, and other documents or information (including any and all copies of such property).

11. Duty to Cooperate. Prior to the Separation Date, the Employee will provide full cooperation to the Company, any related company, and their counsels with respect to any matter, including without limitation, litigation, investigation, audit, or governmental proceeding, which relates to any matter with which the Employee was directly or indirectly involved while employed by the Company.

12. Injunctive Relief. The Employee acknowledges and understands that the remedy at law for his breach of Sections 8, 9, 10, or 11 above will be inadequate, and that the damages flowing from such breach will not be readily susceptible to being measured in monetary terms. Accordingly, upon a violation of any part of Sections 8, 9, 10, or 11 above, the Company will be entitled to immediate injunctive relief and may obtain a temporary order restraining any further violation. Nothing in this Section 12 will be deemed to limit the Company’s remedies at law or in equity for any breach by the Employee of any of the parts of Sections 8, 9, 10, or 11 above which may be pursued or availed of by the Company.

13.. Judicial Modification. The Employee acknowledges that it is the intent of the parties hereto that the restrictions of Sections 8, 9, 10, or 11 above be enforced to the fullest extent permissible under the laws of each jurisdiction in which enforcement is sought. If any of the restrictions in Sections 8, 9, 10, or 11 is for any reason held by an arbitrator or court to be excessively broad as to duration, activity, geographical scope, or subject, then such restriction will be construed or judicially modified so as to thereafter be limited or reduced to the extent required to be enforceable in accordance with applicable law.

14. Joint Communication. The Company or its affiliated companies shall make a public announcement by December 16, 2005 regarding the Employee’s resignation.

15. Arbitration. Any dispute or controversy between the Company and the Employee arising under this Separation Agreement will be settled by arbitration administered by the American Arbitration Association (“AAA”) in Arlington, Virginia pursuant to the AAA’s National Rules for the Resolution of Employment Disputes (or their equivalent), which arbitration will be confidential, final, and binding to the fullest extent permitted by law. BOTH PARTIES HERETO WAIVE THEIR RIGHTS TO SEEK A REMEDY IN COURT, INCLUDING THE RIGHT TO A JURY TRIAL. Notwithstanding the foregoing, to the extent there is no adequate remedy at law and injunctive relief only is sought, the parties hereto select state court in Arlington County, Virginia as the exclusive forum to resolve their disputes, and both parties submit to personal jurisdiction. Either party may be represented by an attorney or other selected representative, provided that each party will be responsible to pay its own attorneys’ or representation fees. The costs of the arbitration and filing fees will be paid by the Company.

16. Entire Agreement. This Separation Agreement contains the entire agreement between the Employee and the Company with respect to its subject matter, and supersedes all prior agreements and understandings, whether oral or written, including without limitation, the Offer Letter, between the Employee and the Company with respect to the subject matter of this Separation Agreement. Notwithstanding the foregoing, the Restricted Stock Agreement executed by Golden Telecom, Inc. and the Employee and dated July 21, 2005 shall remain in full force and effect. This Separation Agreement may be amended only by an agreement in writing signed by both the Employee and the Company.

17. Equity Plan and Restricted Shares. For the avoidance of doubt, the Employee and the Company acknowledge and agree that, provided that the Employee remains in the employ of the Company through the Separation Date, the Employee shall as of the Separation Date hold 2,755 (two thousand seven hundred and fifty-five) unvested shares of restricted shares of Golden Telecom, Inc. common stock; and the Employee acknowledges and agrees that the Employee’s right to all unvested shares of restricted stock held by the Employee as of the Separation Date shall immediately expire, be forfeited, and no longer be of any force or effect. The Employee and the Company acknowledge and agree that any sale, transfer or other disposition, and the validity, termination, and sale, of shares of restricted stock of Golden Telecom held by the Employee as of the Separation Date which are vested will be subject to disposition by the Employee in strict compliance with the 1999 GTI Equity Participation Plan, as amended on June 26, 2001, the Restricted Stock Agreement executed by the Company and the Employee as of July 11, 2005, and all applicable rules and regulations of the US Securities and Exchange Commission and other federal and state regulatory organs.

18. No Other Benefits. The Employee acknowledges and understands that the benefits provided for in this Separation Agreement are the only benefits to which the Employee is entitled, and are the only benefits the Employee will receive, as a result of the separation of his employment with the Company. The Employee further acknowledges and understands that the benefits provided for in this Separation Agreement are inclusive of, and exceed, any benefits to which the Employee is entitled from the Company pursuant to common law, statutory law, contract, or otherwise.

19. Severability. In the event that any of the provisions of this Separation Agreement, or the application of any such provisions to the Employee or the Company with respect to obligations hereunder, is held to be unlawful or unenforceable by any court or arbitrator, the remaining portions of this Separation Agreement will remain in full force and effect and will not be invalidated or impaired in any manner.

20. Waiver. No waiver by any party hereto of the breach of any term or covenant contained in this Separation Agreement, whether by conduct or otherwise, in any one or more instances, will be deemed to be, or construed as, a further or continuing waiver of any such breach, or a waiver of any other term or covenant contained in this Separation Agreement.

21. Governing Law. This Separation Agreement will be governed by, and construed in accordance with, the laws of the Commonwealth of Virginia without giving effect to its conflict of laws principles.

22. Counterparts. This Separation Agreement may be executed in any number of counterparts, each of which so executed will be deemed to be an original, and such counterparts will together constitute but one agreement.

HAVING READ AND UNDERSTOOD THIS SEPARATION AGREEMENT, AND HAVING CONSULTED COUNSEL OR VOLUNTARILY ELECTING NOT TO CONSULT SUCH COUNSEL, AND HAVING HAD SUFFICIENT TIME TO CONSIDER WHETHER TO EXECUTE THIS SEPARATION AGREEMENT, IN WITNESS WHEREOF, the parties hereto have signed this Separation Agreement as of the date first written above.
