previously asserted by them in their First Consolidated Amended Complaint. The group seeks leave to supplement their claims to allege that MasterCard&#146;s proposed initial public offering and certain agreements entered into between MasterCard and
its member banks in connection with MasterCard&#146;s proposed initial public offering (1)&nbsp;violate Section&nbsp;7 of the Clayton Act because their effect allegedly may be to substantially lessen competition, (2)&nbsp;violate Section&nbsp;1 of
the Sherman Act because they allegedly constitute an unlawful combination in restraint of trade and (3)&nbsp;constitute a fraudulent conveyance because the member banks are allegedly attempting to release without adequate consideration from the
member banks MasterCard&#146;s right to assess the member banks for MasterCard&#146;s litigation liabilities in these interchange-related litigations and in other antitrust litigations pending against it. </FONT></P> <P
