MarketWatch Merger and Pinnacor Merger and are wholly owned subsidiaries of the
Company. GAP 69, GapStar and GAPCO II were shareholders of Pinnacor. Pursuant to
the Merger Agreement, shareholders of Pinnacor were entitled to elect to
receive, for each share of Common Stock of Pinnacor, either $2.42 in cash,
0.2659 shares of Common Stock or a combination of both. The final allocation of
the consideration issued pursuant to the Merger Agreement has not been
determined, but each of GAP 69, GapStar and GAPCO II elected to receive shares
of Common Stock and anticipates receiving 1,551,692 shares of Common Stock,
119,496 shares of Common Stock and 240,751 shares of Common Stock, respectively.

                  GAP 69, GapStar and GAPCO II acquired the shares of Common
