6. Terms and Conditions Applicable to Options.

6.1 Non-Transferability. An Option granted hereunder shall not be transferable by the Optionee to whom granted except by will or the laws of descent and distribution, and an Option may be exercised during the lifetime of such Optionee only by the Optionee or (in the case of incapacity) his or her guardian or legal representative. The terms of such Option shall be final, binding, and conclusive upon the beneficiaries, executors, administrators, heirs, and permitted successors of the Optionee.

6.2 Method of Exercise. The exercise of an Option shall be made only by a written notice delivered in person, by mail or facsimile transmission to VimpelCom at its principal executive office or other address provided by VimpelCom, specifying the number of Shares to be purchased. Once the written notice is approved by VimpelCom as being in accordance with the Plan and an Agreement pursuant to which the Option was granted, the Exercise Price for any Shares purchased pursuant to the exercise of an Option shall be paid, as determined by the Committee in its discretion, in the following manners (or any combination thereof): (i) wire transfer or in cash, (ii) the transfer of Shares, upon such terms and conditions as determined by the Committee, or (iii) the Options may be exercised through a registered broker-dealer or other legally permitted cashless exercise procedures which are, from time to time, deemed acceptable by the Committee. Any Shares transferred to VimpelCom or an Affiliate as payment of the Exercise Price under an Option shall be valued at the NYSE Fair Market Value of the DRs on the day preceding the date of exercise of such Option and shall again be available for future grant under the Plan. In addition, any Shares withheld by VimpelCom as payment of the Exercise Price under a cashless exercise procedure shall also become available again for future grant under the Plan (and shall be disregarded for the purposes of Section 4.1). No fractional Shares (or cash in lieu thereof) shall be issued upon exercise of an Option and the number of Shares that may be purchased upon exercise shall be rounded to the nearest number of whole Shares.

6.3 Rights of Optionees. Optionee shall not be deemed for any purpose to be the owner of any Shares subject to any Option unless and until (i) the Option shall have been exercised pursuant to the terms thereof, (ii) VimpelCom shall have delivered the transfer order for the Shares to the Optionee, and (iii) the Optionee’s name shall have been entered as a shareholder of record on the register of members of VimpelCom (or through a nominee holder); thereupon, the Optionee (or his nominee, if held by a nominee holder) shall have full voting, dividend, and other ownership rights with respect to such Shares, subject to such terms and conditions as may be set forth in the applicable Agreement.

7. Adjustment Upon Changes in Capitalization.

7.1 In the event of a Change in Capitalization, the Committee shall have the sole discretion to conclusively determine the appropriate adjustments, if any, to (i) the maximum number and class of Shares or other securities with respect to which Options may be granted under the Plan, (ii) the maximum number and class of Shares or other securities with respect to which Options may be granted to any Eligible Individual during the term of the Plan, and (iii) the number and class of Shares or other securities which are subject to outstanding Options granted under the Plan and the Exercise Price therefor, if applicable.

7.2 If, by decision of the Committee upon a Change in Capitalization, an Optionee shall be entitled to exercise an Option with respect to new, additional, or different shares or securities, such new, additional or different shares or securities shall thereupon (subject to applicable law) be subject to all of the conditions, restrictions, and performance criteria which were applicable to the Shares subject to the Option prior to such Change in Capitalization.

8. Effect of Certain Transactions; Liquidation or Dissolution. Except as otherwise provided in this Plan or in an Agreement, in the event of merger, amalgamation, scheme of arrangement, consolidation, or similar business combination of VimpelCom (a “Transaction”), the Plan and the Options issued hereunder shall continue in effect in accordance with their respective terms, except that following a Transaction each Optionee shall be entitled to receive in respect of each Share subject to any outstanding Options, upon exercise of any Option, the same number and kind of stock, securities, cash, property, or other consideration that each holder of a Share was entitled to receive in the Transaction in respect of a Share; provided, however, that such stock, securities, cash, property, or other consideration shall remain subject to all of the conditions, restrictions, and performance criteria which were applicable to the Options prior to such Transaction. Except as otherwise provided in this Plan or in an Agreement, in the event of liquidation or dissolution of VimpelCom, each Optionee will be entitled to equitable treatment as determined by the Committee in its sole discretion.

9. Termination and Amendment of the Plan. The Plan shall terminate on December 31, 2020, and no Option may be granted thereafter. The Committee may sooner terminate the Plan and the Committee may at any time and from time to time amend, modify or suspend the Plan, including this Section 9; provided, however, that to the extent necessary under applicable law, no amendment shall be effective, unless approved by the shareholders of VimpelCom and the Board in accordance with applicable law.

10. Non-Exclusivity of the Plan. The adoption of the Plan by the Board shall not be construed as amending, modifying or rescinding any previously approved option plans of VimpelCom or any Affiliate or as creating any limitations on the power of VimpelCom or any Affiliate to adopt such other option plans as it may deem desirable, including, without limitation, the granting of share options otherwise than under the Plan, and such arrangements may be either applicable generally or only in specific cases.

11. Limitation of Liability. As illustrative of the limitations of liability of each of VimpelCom or any Affiliate, but not intended to be exhaustive thereof, nothing in the Plan shall be construed to:

(a) give any person any right to be granted an Option other than at the sole discretion of the Committee;

(b) give any person any rights whatsoever with respect to Shares except as specifically provided in the Plan and an Agreement; or

(c) limit in any way the right of VimpelCom or any Affiliate to terminate the employment of any person at any time.

12.3 The Committee may make such changes as may be necessary or appropriate to comply with the rules and regulations of any government authority or of any stock exchange on which the Shares or DRs are listed or traded.

12.4 Each Option is subject to the requirement that, if at any time the Committee determines, in its discretion, that the listing, registration, or qualification of Shares issuable pursuant to the Plan is required by any securities exchange or under any law, or the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the grant of an Option or the issuance of Shares, no Options shall be granted or payment made or Shares issued, in whole or in part, unless listing, registration, qualification, consent, or approval has been effected or obtained.

6

12.5 Notwithstanding anything contained in the Plan or any Agreement to the contrary, in the event that the disposition of Shares acquired pursuant to the Plan is not covered by a then current registration statement under the Securities Act and is not otherwise exempt from registration, such Shares shall be restricted against transfer to the extent required by the Securities Act and Rule 144 or other regulations thereunder, and the certificate, if any, evidencing such Shares will be imprinted with a legend setting forth such restriction. The Committee may require any individual receiving Shares pursuant to an Option granted under the Plan, as a condition precedent to receipt of such Shares, to represent and warrant to VimpelCom and/or an applicable Affiliate in writing that the Shares acquired by such individual are acquired without a view to any distribution thereof and will not be sold or transferred other than pursuant to an effective registration thereof under the Securities Act or pursuant to an exemption applicable under the Securities Act or the rules and regulations promulgated thereunder.

13. Miscellaneous.

13.1 Multiple Agreements. The terms of each Option may differ from other Options granted under the Plan at the same time, or at some other time. The Committee may also grant more than one Option to a given Eligible Individual during the term of the Plan, either in addition to, or in substitution for, one or more Options previously granted to that Eligible Individual.

13.2 Withholding of Taxes. If VimpelCom or any of its Affiliates are required, by any applicable law, to report income or to withhold personal income tax or social security contributions from the Optionee in connection with the grant, vesting or exercise of an Option at the time of such events, the Optionee shall (i) undertake to cooperate to facilitate such reporting or withholding and shall bear costs relating thereto, (ii) declare any income reportable in connection with such events in full compliance with applicable law, (iii) make timely settlement of any taxes or social security due from the Optionee, and (iv) reimburse VimpelCom or its Affiliates, as applicable, for any such payments made by VimpelCom or its Affiliate on behalf of Optionee.
