Agreement and Plan of Merger are fair to and in the best interests of
TradeStation and its shareholders. The TradeStation board also unanimously
adopted and approved the Agreement and Plan of Merger, declared advisable the
Agreement and Plan of Merger, the tender offer and the other transactions
contemplated therein and recommended that shareholders of TradeStation accept
the tender offer and tender their shares to the Merger Sub and, if required,
approve the Agreement and Plan of Merger (including the plan of merger) and the
subsequent merger.

The tender offer is scheduled to expire at 12:00 midnight, New York City time,
on Tuesday, June 7, 2011, unless the tender offer is extended. If the tender
offer is extended, Monex and/or Purchaser will inform the depositary for the
offer and will make a public announcement of the extension not later than 9:00
a.m., New York City time, on the next business day after the previously

basis, as well as receipt of antitrust clearance, approvals and consents from

Services Authority with respect to the transactions contemplated by the

offer documents. Following completion of the tender offer and, if required,
receipt of shareholder approval, Monex expects to consummate a second-step
merger in which remaining TradeStation shareholders will receive the same cash
price per share as paid in the tender offer. Following the merger, TradeStation
will become a wholly-owned subsidiary of Monex.
