                  (b) Charter Capital. As of the date hereof the authorized
charter capital of the Company consists of 140 ordinary registered shares, all
of which have been issued to, and are registered in the name of, Khachaturyan,

Interest. Leibov is the sole beneficial owner of the Option Shares which are

Leibov is bound. This Agreement is a valid and binding agreement of Leibov and
is enforceable against Leibov in accordance with its terms, except as such
enforcement is limited by bankruptcy, insolvency and other similar laws
affecting the enforcement of creditors' rights generally.

                  (e) Appointment of Investor Representatives on Company's
Board. Upon the Investor's timely exercise of the option granted hereunder,

         4. Capital Contribution to be Made by the Investor; Preferential
Distributions; Return of Option Shares in Certain Circumstances.

                  (a) Capital Contribution. In the event that the Investor

agrees that it will establish, in accordance with the Currency Law of the
Russian Federation, and Instruction 16 of the Central Bank of the Russian
Federation, a type "I" special rouble account at an authorized bank located

after the closing of the Investor's initial public offering of securities (the
"IPO") in the United States of America (the "Closing Date").

                  (b) Preferential Distributions. Leibov and the Investor hereby
agree that: (i) in the event that the Company makes any distributions of charter
capital in respect of its ordinary registered shares, the entire amount of any
such distribution shall be allocated and paid to the Investor until such time as
it shall have recouped $425,000 of its additional capital contributions to the
Company; and ii) after the Investor shall have recouped $425,000 of its
additional capital contributions, all further distributions by the Company in
respect of its ordinary registered shares shall be made on a pro rata basis.

                  (c) No IPO Closing. In the events that (i) the Investor
withdraws the IPO prior to the declaration of effectiveness by the Securities
and Exchange Commission (the "Commission") of the Registration Statement
pertaining thereto, or (ii) the Investor otherwise ceases to proceed with
registration under the Securities Act of 1933 of the securities it intends to
offer to the public in its IPO, or (iii) J.W. Barclay & Co., Inc. fails, for any
reason, to seek an order of effectiveness of said Registration Statement from
the Commission on or before December 31, 1997, then, upon Leibov's payment of
the sum of $95,000 to the Investor, the Investor shall transfer all of its
right, title and interest in all of the Option Shares to Leibov. In such event,
the Investor hereby covenants and agrees that it will execute all instruments
and documents, and undertake all actions necessary to cause the Company's
Charter to be amended, and as so amended, to be re-registered with the
appropriate governmental authorities, to record the transfer of ownership of the
Investor's ownership of 105 ordinary registered shares of the Company's Charter
