                    but do not achieve the Tier I Target shall be based on a
                    linear interpolation between 0% of the annual base salary at
                    the Minimum Bonus Threshold and the potential Tier I Target
                    bonus.

                    successful launch of the AOL service in the three core
                    markets, target subscriber acquisitions for each of the core
                    markets and overall management of the Joint Venture's cash
                    expenditures and finances over each 12-month period, such
                    target objectives to be agreed following steering committee
                    approval of the annual business plan. The first bonus year
                    will be the fiscal year beginning July 1,1999.

                    provisions below, the stock options shall have a 10-year

                    such programs are substantially less favorable to that
                    currently provided the Executive, AOL will provide him with

                    coverage shortfall, provided, that the aggregate cost of

                    term of the Executive's employment the Joint Venture will
                    pay the Executive's annual country club dues of US$11,000,
                    as adjusted from time to time.

                    the event the Executive's employment is terminated by the
                    Joint Venture without "Cause" (as hereinafter defined). If
                    such termination occurs prior to the second anniversary of
                    the Effective Date, during the thirty six month period
                    following such termination, the Executive will continue to
                    receive his base salary, payable at the same time and in the
                    same manner as if the Executive's employment had continued

                    bonus for the fiscal year during which termination occurs,
                    payable following the end of such fiscal year. In addition,
                    the Executive will continue to vest with respect to
                    previously granted stock options as if his employment had
                    continued during such applicable severance payment period.
                    Any such severance benefits will be reduced by the amount of
                    income earned by the Executive during such severance payment
                    period.

                    "Cause" shall mean either of the following circumstances:
                    (i) the Executive's willful violation of material Joint

                    written notice of such violation by the board of directors
                    of the Joint Venture (the "Board"); (ii) the Executive's
                    failure to comply with the lawful direction of the Board;
                    (iii) the commission by the Executive of a material act of
                    dishonesty or fraud; or (iv) the Executive's conviction or
                    plea of no contest to a felony.

                    Termination for Cause. The Executive will receive no
                    ---------------------
                    payments from the Joint Venture other than amounts accrued
                    and owing to him as of the termination date. All unexercised
                    stock options, whether vested or unvested, shall immediately
                    lapse and become void.

                    Other Termination or Resignation.  In the event that the
                    --------------------------------
                    Executive's employment terminates for any reason, other that
                    those listed above; he shall be entitled to retain his
                    vested stock options. All his unvested stock options shall
                    immediately lapse and become void.

                    Terms Applicable to Termination for Any Reason. In the event
                    ----------------------------------------------
                    that the Executive's employment terminates for any reason,
                    he will receive his base salary through the date of
                    termination. The Executive will not receive any further
                    grants of stock options after the termination date. Vested
                    stock options must be exercised by the Executive within a
                    certain period after the termination date or after such
                    options become vested, as the case may be, in accordance
                    with the applicable stock option plan and stock option
                    agreement.
