The Role of Specialists in the NYSE Market A specialist performs five essential functions in the specific securities allocated to him or her: Manage the opening process. To maintain a fair and orderly market in a particular security, the specialist oversees the establishment of the opening price for his security every day. Execute orders for floor brokers. The specialist can execute an order immediately or hold the order and execute it when the stock reaches the specific price requested by the customer. As a dealer, the specialist will buy or sell stock from his own inventory to keep the market liquid or to prevent rapid price changes. Serve as catalysts. Specialists are the point of contact between brokers with buy and sell orders. The specialist acts as a catalyst, bringing buyers and sellers together enabling a transaction to take place that otherwise would not have occurred. Provide capital. If buy orders temporarily outpace sell orders, or conversely if sell orders outpace buy orders, the specialist is required to use his firm's own capital to minimize the imbalance. Usually public order meets public order without specialist participation, however, specialists do participate in less than 10 percent of all shares traded. Stabilize prices. To ensure that stock trading moves smoothly, with minimal price fluctuation, the specialist will step in against the market trend. Specialists buy and sell stock to cushion temporary imbalances and to avoid unreasonable price variations. #### Important Acquisition Information With Respect To The Merger In connection with the proposed merger of the New York Stock Exchange, Inc.
