         business hours in the period between the date hereof and the Closing
         Date to the properties, books, contracts and records of Cabletel and

         the Closing Date, except as an employee of the company or one of its
         subsidiaries or as a stockholder of the Company, none of the Holders
         will conduct any business or enter into any transaction relating to
         telecommunications and information services business in the Republic of
         Bulgaria, unless the events described in paragraph 16(c) result in the
         Holders acquiring, directly or indirectly, Cabletel.

                  (d) No Brokers. All negotiations relative to this Agreement,
         and the transactions contemplated hereby have been carried on by each
         of the Holders and the Company directly without the intervention of any
         other Person as the result of any act of any of the Holders or the
         Company which might give rise to any valid claim against any of the
         parties hereto for a brokerage commission or like payment. Each of the
         parties hereto hereby agrees to indemnify, save and hold harmless all
         other parties from and against any such claim of any such Person.

         the operation of their respective businesses. Each of the parties
         hereto agree to keep all such information confidential, to restrict its
         circulation to those of its employees, counsel, financial advisors and
         lenders necessary for the accomplishment of the transactions
         contemplated by this Agreement. Without prior consultation and
         agreement, none of the parties hereto shall make any public disclosure
         of the fact of this transaction, the parties hereto, the terms hereof
         or any other matter related hereto, and the parties hereto shall each
         use their respective best lawful efforts to avoid such publicity in any
         meeting; provided, however, that the Company may unilaterally release
         such information to the general public as it, or its counsel, may deem
         appropriate to fulfill the Company's obligations

         under applicable federal and state securities laws, including filings
         required under the Exchange Act and disclosure to the American Stock
         Exchange, Inc. ("AMEX").

         12. Special Covenants. The parties to this Agreement and each
certificate representing shares of Preferred Stock initially issued to the
Holders pursuant to this Agreement shall be subject to the following provisions
of this Agreement for the reasons and as set forth below:

                  (a) Transfer Restriction. The Preferred Stock shall only be
         transferable in transactions which shall be exempt from the
         registration requirements of the Act. Each of the Holders of such
         Preferred Stock, by acceptance thereof agrees, that an appropriate
         legend shall remain on the certificates representing such shares to
         give notice to any potential purchaser that no transfer of such shares
         shall be valid or effective until certain conditions have been
         fulfilled. Each of the Holders of such shares of Preferred Stock, by
         acceptance thereof, agrees, prior to any proposed transfer, to give
         written notice to the Company expressing such holder's intention to
         effect such transfer and describing briefly the manner of the proposed
         transfer. Promptly upon receiving such notice, the Company shall
         present copies thereof to its counsel and if such proposed transfer is
         an exempt transaction under the Act, the Company shall permit such
         transfer subject to the transferee agreeing to be bound by the terms
         and provisions of this Agreement.

                  (b) Requisite Stockholder Approval of Transaction and any
         Subsequent Exchange; Voting Agreement. Notwithstanding any other
         provision of this Agreement, as soon as reasonably practicable and in
         no event later than September 30, 2005, the Company shall have
         presented the transaction represented by this Agreement, together with
         the proposed mandatory exchange of Preferred Stock for Common Stock
         described below to its current stockholders in accordance with
         applicable requirements of the Commission and the AMEX for a vote (or
         written consent by the requisite number) of such stockholders to
         approve the transaction evidenced by this Agreement and a mandatory
         exchange of all shares of Preferred Stock for shares of the Company's
         Common Stock on the basis of 279 shares of Common Stock for each share
         of Preferred Stock, to result in an aggregate of 8,788,500 shares of
         Common Stock to be issued to the Holders (or their respective
         transferees) which shall then constitute at least 89% of the total
         issued and outstanding shares of Common Stock of the Company, all of
         which shall be subject to the listing requirements with the AMEX, but
         may not be required to be registered pursuant to the Act.

                  (c) Potential Recission. In the event that the stockholders of
         the Company do not approve by the requisite number of votes either the
         transaction covered by this Agreement or the mandatory exchange of
         shares of Common Stock for shares of Preferred Stock described in (b)
         above, the Holder(s) of the Preferred Stock shall have the option,
         exercisable by all, but not less than all Holders, at any time after
         September 30, 2005 until 12:00 noon, local Dallas, Texas time on
         September 30, 2006 (herein called the "Put Option"), to either (i)
         rescind in full and revoke the transaction covered by this Agreement by
         returning all 31,500 shares of Preferred Stock to the Company upon
         which the Company shall, within two Business Days, deliver back to such
         Holder(s) all equity securities of any entity owning all of the
         ordinary shares and other securities of Tacaruna or of Cabletel, or
         (ii) deliver to the Company all 31,500 shares of Preferred Stock of the
         Company and receive in exchange therefor all of the ordinary shares and
         other securities of Tacaruna outstanding and owned by the Company such
         that such Holder(s) shall become the owner and holder of all of the
         issued and outstanding securities of Tacaruna which in turn continues
         to own Cabletel.

                  (d) Reimbursement for Governmental Compliance. In the event
         that the business or properties which FEINC or ARM or Tacaruna or
         Cabletel will own or use at Closing are not as of that date in
         compliance with all rules and regulations of any governmental body or
         agency with jurisdiction over it, and in the event that substantial
         efforts are required to secure such compliance, the Holders shall
         reimburse the Company for all reasonable and necessary monies expended
         by the Company alone in order to secure such compliance.

                  (e) Tax Indemnification. Upon written notice by the Company,
         the Holders shall pay to the Company or Tacaruna, as appropriate, and
         shall otherwise indemnify, save and hold the Company and Tacaruna
         harmless from and against the amount of any assessment against,
         asserted or paid by or on behalf of Cabletel relating to or arising out
         of the years in which Cabletel was not owned by Tacaruna or was a
         member of an affiliated group (for which consolidated income tax
         returns were filed by an entity other than the Company or Tacaruna)
         under the Internal Revenue Code of 1986, as amended (the "Code"), as
         applicable, or any other taxing authority with respect to any
         deficiency asserted by the Internal Revenue Service or such other
         taxing authority based upon any income tax returns filed under the Code
         or other taxing authority by Cabletel for any period up to and
         including the Closing Date hereof or for any tax liability arising
         against Cabletel prior to the Closing Date which is not reflected in
         the Financial Statements included on Schedule 1. The Holders shall also
         be obligated under this paragraph 10(e) for any such assessment caused
         by any act or failure to act on the part of the Holders after the date
         hereof.

         Holders shall also pay to the Company or Tacaruna, as the case may be,
         the amount of any tax refund received by the Holders attributable to
         tax payments by Cabletel after the Closing Date which refund is

         waived;

                  (d) by any party to this Agreement if the Closing has not
         taken place by the close of business on November 19, 2004.

Any party may, at their election, waive any or all of its foregoing rights to
terminate this Agreement and shall be deemed to have waived those rights upon
the Closing of this Agreement to the extent such waiver is made with actual
knowledge of such termination right. If the Closing of the transactions under

control to carry out performances contemplated by this Agreement, no party to
this Agreement shall be liable to any other party for any loss, damage or
expense, and the only remedy shall be to terminate this Agreement by notice to
the other parties as to the underperformed part of this Agreement.

         fees incurred or assumed by such party in the preparation or execution

         herein, whether or not the transactions contemplated hereby shall be
         consummated.

                  (b) Notices. Any notice or other communication required or
         permitted to be given by this Agreement or any other document or
         instrument referred to herein or executed in connection herewith must
         be given in writing (which may be by telecopy followed by mail or
         personal delivery), and must be personally delivered or mailed by

         or communication is directed, at the address of such party set forth

         the other provisions of this Agreement, any party may change its

         delivered) for purposes of this Agreement by giving notice of such
         change to the other party pursuant to this section. In each instance,
         with respect to any such notice so given, it shall only be effective
         upon receipt by the party intended to receive same.

                  (c) Further Cooperation. To the extent that any party's
         further approval or other action is deemed necessary or desirable by

         Agreement and the conveyances, the

         representations, warranties or conditions hereof may be waived, but

         construed as a as a further or continued waiver of any condition or any
         breach of any other term, covenant, representation or warranty in this
         Agreement. This Agreement and each revision hereof may not waived,
         altered, amended or modified, except in writing, duly executed by both
         parties.
