                                 Consideration

1.  As consideration for the 39,200 shares of Novento Stock sold with this
    agreement, the Sellers shall receive:

    a)  A sum of DM 1,902,000 (in words: one million nine hundred two thousand
        German marks); and

    b)  Shares of common stock held by the Buyer, the number of which is to be
        defined according to subsection 5 (hereinafter referred to as "Cybernet
        Stock)

2.  The division of the consideration according to the preceding subsection 1
    shall be effected between the Sellers 2-6 in the ratio of stock held by
    them with the requirement that the Seller 2 shall be paid its full purchase
    price entitlement in cash. Any cash amount beyond this amount is due to the
    other Sellers in the ratio of their shares.
<PAGE>

3.  As consideration for the 19,600 shares of Multicall stock sold with this
    agreement the Seller 1 shall receive a sum of DM 98,000.00 (in words: eight
    hundred ninety thousand German marks).

4.  The preceding considerations are payable within 4 weeks from occurrence of
    the condition precedent in accordance with preceding (S) 2 subsection 1.

5.  The consideration according to the preceding figure 1 b) is based on the
    consolidated interim report of the companies for the period ended November
    30, 1999 for the months of September, October and November 1999
    (hereinafter referred to as "the interim report"). The interim report shall
    be established according to the principles of proper accounting (with the
    requirement that receipts not received by December 10, 1999 may be
    estimated) by the auditor Mr Klosterkamp in a manner that is binding to the
    parties and shall then be distributed to the parties. The net sales
    receipts specified in the interim report depend on the profit before
    interest, taxes and amortization (hereinafter referred to as "EBITDA")
    without consideration of the board of director's salaries, shall be
    multiplied in a consolidated manner with the multiplicators A and B as
    resulting from the scheme attached in Annex 2. This base price for the
    whole enterprise shall be multiplied by 0.49 and thereafter the amount of
    DM 1,902,000.00 shall be subtracted so that the value of the consideration
    according to the preceding subsection 1, letter b) results and which in any
    case is no higher than DM 8,000,000 (in words: eight million German marks).
    This value shall be divided by the stock exchange price of the Cybernet
    stock. The EURO 12.00 shall prevail or, where a smaller amount results, the
    average of the relevant day closing price of the Cybernet stock (Securities
    No. WP-Kenn-Nr. 906 623) at the Frankfurt Stock Exchange in the week
    immediately preceding the occurrence of the precedent condition in
    accordance with the preceding (S)2 subsection 1, less 20%.

6.  The Buyer may have the interim report audited by Schitag Ernst & Young
    Wirtschaftsprufungsgesellschaft by March 31, 2000. Where turnover figures
    reduced by 10 percent due to this audit result, the consideration according
    to the preceding subsection 5 shall be newly established based on the
    audited interim report. Any shortfall compared with subsection 5 shall be
    balanced by May 15, 2000 by returning the relevant Cybernet stock to the
    Buyer. Where the average day closing price of the Cybernet stock in April
    2000 is smaller
<PAGE>

    than the price prevailing under the preceding subsection 5, the
    consideration shall be newly determined based on this lower price and any
    increase in the consideration according to this subsection 6 shall be
    balanced by May 15, 2000 by transferring the relevant Cybernet stock to the
    Sellers.

7.  The percentage of the consideration according to the preceding subsection
    1.b) shall be reduced to the extent the number of Novento AG customers on
    March 31, 2000 falls short of the number of customers on November 30, 1999.
    Only business customers producing a monthly turnover of at least DM 200.00
    shall be taken into account. Slight deviations up to 5% shall not lead to a
    reduction of the purchase price. A reduction of the consideration according
    to this subsection 6 shall be balanced by May 15, 2000 by returning the
    relevant Cybernet stock to the Buyer.

                                     (S) 4

        proper accounting and balance sheet preparation while maintaining
        balance sheet continuity by the auditors/tax consultants/lawyers

        date, except for those sold since December 31, 1998 in proper business
        transactions. The assets of the companies, except for the reservations

        713), which are always free of rights of third parties.

    h)  The Sellers have left the Buyer all agreements essential to the
        company, completely and correctly in the original or as a copy for
        inspection, including the reseller agreement with Star

        commercial agent agreement, and the cooperation agreement of Novento
        AG with Multicall AG dated September 1, 1998. Apart from the

        backed by an adequate consideration.

    i)  With the exception of the employment contracts of Mr Bernd Buchholz and
        Mr Jochen Boekel and the known loan contracts there are no contracts
        or agreements between the companies and the Sellers or persons close
        to them.

    k)  Except for the staff agreements (commissions system) and the commercial
        agent agreements, the companies have not signed any agreements with
        profit- or sales-dependent remuneration, royalties etc.

    l)  The Sellers have made all staff agreements with the companies available
        to the Buyer for inspection as a true and complete copy or in the
        original. Further employments, other agreements, plant agreements or
        commitments from operations do not exist. Claims from a stock option
        programme against the companies do not exist at the transfer date.

    m)  There are no untypical guaranties, sureties or similar charges (surety
        Colt for DM 30,000.00, guaranty commitments from rental agreements are
        known). The companies assume no liabilities from furnishing collateral
        for external commitments. The companies have given no promises of
        loans.

    n)  There are no known public-legal restrictions that could prevent the
        companies from running their operations in the way they do it now.
<PAGE>

    o)  At present, except for Kirchhoff versus Multicall, the companies are
        conducting no litigation. Procedures against the companies before
        administrative authorities or official investigations are neither
        impended nor do they have to be expected to the best of one's
        knowledge. The Buyer knows that presently Novento AG is withholding
        sums from Star Telecom because of alleged compensation claims.

    p)  The companies submitted all income tax revenues properly and timely and
        paid all due taxes or accumulated sufficient reserves for taxes.
        Furthermore, the companies have no arrears in taxes and no tax risks.
        Payments to staff for payroll tax and for contributions to legal
        insurances have been adequately determined, calculated and
        transferred.

    q)  For the companies there are no commitments outside usual business
        transactions.

    r)  The Seller Mr Buchholz is free of rights of third parties in handling
        the Multicall claim. The loan agreements are true and complete. The
        priority-related notices of rescission shall be observed.

2.  If one of the above warranties proves incorrect or is not complied with,
    the Sellers shall place the Buyer, or after election of the Buyer, the
    companies in the situation the Buyer and the companies would be in, if the
    warranty were correct or had been complied with. One or several claims up
    to an amount of a total of DM 100,000.00 shall not be taken into account.

3.  In accordance with the above subsection 2 and regardless of it, the Sellers
    shall release the companies from compensation due to liabilities in
    connection with the incorrectness or violation of the above warranties.

4.  The Buyer may raise any claims resulting from the above subsections 2 and 3
    until December 31, 2000, furthermore any claims in connection with the
    implementation of a tax field audit of the companies within six months from
    receipt of the legally effective advice based on such a tax field audit. In
    order to comply with the deadline, it is sufficient to inform the Sellers
    of the claims in
<PAGE>

    writing. After receipt of such information a one-year period of limitation
    commences.

5.  To the extent the Sellers are affected by a tax audit (taxes and levies) of
    the companies covering the period up to the transfer date, the Buyer shall
    take care that the Sellers are able to participate at their own costs and
    by an authorized person who is professionally committed to a duty of
    discretion. To the extent the Buyer does not appeal, the Sellers may use
    the legal remedies they consider appropriate for their own account and on
    behalf of the companies. In such a case the Buyer shall take care that the
    Sellers are timely given all the necessary information or powers of
    attorney. Any additional tax payment or other payment due to such tax audit
    shall be borne by the Sellers, unless otherwise provided by this agreement.

6.  A rescission shall be excluded. Furthermore, the regulation contained in
    the above subsections 2 and 3 does not limit or exclude the legal claims
    and rights of the Buyer.

1.  The Buyer warrants to the Sellers as of the transfer date and this day of
    signing this agreement:

    a)  The Buyer is free to handle the Cybernet Stock without restrictions and
        rights of third parties. The Sellers know that transferability of

        law, it is validly existing and in "good standing". With the exception
