THE PHILADELPHIA STOCK EXCHANGE ANNOUNCES LAUNCH OF THE PHLX MARINE SHIPPING INDEXTM (SHXSM) ON
MARCH 14

PHILADELPHIA - March 14, 2007 – The Philadelphia Stock Exchange announced today
the launch of the PHLX Marine Shipping Index^TM (SHX^SM). Options on the SHX are slated to be launched at a later date.

PHLX Marine Shipping Index (SHX) seeks to reflect the performance of publicly listed companies primarily involved in worldwide seaborne transportation of liquid goods of crude oil, petroleum products, chemicals, and dry goods of iron ore and agricultural commodities. The index had a start date of March 1, 2007 and a beginning price level of 250. The index is comprised of 17 companies and is equal-dollar weighted.

"Marine shipping represents a sector that is four times the 100-day historical volatility of the S&P 500 and is essentially inversely correlated to the price of crude oil," said Daniel R. Carrigan, PHLX’s vice president of new product development. "Additionally, SHX tends to lead crude oil price moves by as much as one week worth of trading days” he said.

The Philadelphia Stock Exchange was founded in 1790. The PHLX trades more than 7,000 stocks, 2,340 equity options, 15 sectors index options and currency options. For more information about the PHLX and its products, visit www.phlx.com.
