Company;



(ii) The Company shall have a right of first refusal
to pursue any such Opportunity, exercisable at no cost to the Company. The Board shall determine whether to exercise such right and pursue such Opportunity in accordance with the Management Regulations of the Company. If the Board determines that
the Company should pursue such Opportunity, the Company shall, within fifteen (15) days of receipt of such notice from such Party, notify such Party that the Company has elected to exercise its right of first refusal in respect of such Opportunity.
Thereafter, the Company may pursue such Opportunity as it shall, in its sole discretion, see fit, and such Party shall desist from pursuing such Opportunity;



(iii) If the Board determines that the Company should not pursue such Opportunity, the Company shall, within fifteen (15) days of receipt of such
notice from such Party, notify such Party that the Company has elected not to exercise its right of first refusal in respect of such Opportunity. If such Party decides to pursue such Opportunity, it shall do so through a Russian special purpose
vehicle established solely for the purpose of owning and developing such Opportunity. Such special purpose vehicle shall have financial statements audited in accordance with GAAP commencing from the date of its establishment prepared by an
internationally recognized accounting firm. In such event:



(A) With respect to any Opportunity for which notice was given pursuant to Section 5.02(c)(i) prior to the second anniversary of the Closing, and with respect to any Opportunity in any subject (subyekt) of the Russian Federation in
which the Company then holds a license to engage in the Business for which notice was given pursuant to Section 5.02(c)(i) on or after the second anniversary of the Closing, the Company shall have a call option in respect of all of such Partys
right, title and interest in and to the Opportunity, exercisable within three (3) years from the date of such Partys notice to the Company pursuant to Section 5.02(c)(i) at an exercise price equal to the greater of the Fair Market Value of

respect of all of such Partys right, title and interest in and to the Opportunity, exercisable within two (2) years from the date of such Partys notice to the Company pursuant to Section 5.02(c)(i), at an exercise price equal to the

the Company and the Company shall decide, prior to the expiration of such thirty (30) day period, whether to initiate the due diligence process set forth in Section 5.02(c)(iv) and thereafter, to exercise its call option in accordance with and
subject to the terms described in this Section 5.02;



(iv)
With respect to each call option described in Section 5.02(c)(iii), the Board shall determine whether to exercise such call option in accordance with the Management Regulations. If the Board determines that the Company should exercise such call
option, the Company shall, at least ninety (90) days prior to the end of such two (2) year period or three (3) year period, as the case may be, notify such Party that, subject to due diligence, obtaining the necessary approvals from all Governmental
and Regulatory Authorities and obtaining the representations and warranties, and guarantee set forth below, the Company wishes to exercise such call option. The Company shall have sixty (60) days to conduct a due diligence investigation in respect
of such Opportunity, commencing on the date on which the Board notifies such Party of the Companys wish to exercise such call option. Such Party shall cooperate with the Company in connection with such due diligence investigation and, upon
request of the Company, its counsel, auditors or financial advisors, provide the Company with all documents and other information concerning such Opportunity. In addition, such Party agrees that it will not vote any of its Shares and/or New
Securities (and, in the case of Eco Telecom, exercise any other rights provided hereunder) against the sale or issuance by the Company of any shares of capital stock (provided such Party is given the opportunity to participate on a pro rata basis in
order to maintain its shareholding in the Company, and that such Party may make payment for such portion of the shares of capital stock of the Company by contributing the Opportunity (in whole or in part) to the Company (based on the Fair Market
Value of the Opportunity)), or the borrowing by the Company of any public debt securities, in each case, the proceeds of which will be used to finance, directly or indirectly, the purchase of such Opportunity. If following such due diligence
investigation the Company still wishes to exercise such call option, it shall, at least thirty (30) days prior to the end of such two (2) year period or three (3) year period, as the case may be, notify such Party thereof and instruct its counsel to
prepare definitive documentation to effect the exercise of such call option, which definitive documentation will include the following:

form of Schedule 5.02(c)(iv)(C).

Company has not exercised such call option due to the failure of such Party to meet the requirements set forth in Section 5.02(c)(iv) within ninety (90) days from the date the Company notified such Party of its election to exercise the call option
