EPX Brochure, Components and Specifications, Strike Prices

PHILADELPHIA – Jul. 12 2005 - The Philadelphia Stock Exchange (PHLX) announced today that it will begin trading options on the SIG Oil Exploration & Production Index (EPX) on July 19. Cash options on EPX will trade on PHLX XL, the Exchange’s electronic trading platform, along with 22 other PHLX proprietary indexes. The index has been allocated to Susquehanna Investment Group.

“EPX allows traders to capture the performance of the leading oil and gas exploration and production companies,” said PHLX Vice President of New Products, Daniel Carrigan. “With crude oil hitting new highs each week and Northeastern states beginning to stockpile heating oil for the upcoming winter, this sector will be characterized by significant volatility, hence the need for a hedging vehicle.”

“EPX represents a critical sector underserved by other benchmarks and derivatives,” said SIG Indices President, Jamie Farmer. “SIG is committed to delivering innovative risk management tools for the trading and brokerage community,” he said.
