• Builds Upon Industry-Defining, Flat-Rate $9.95 Options Commission, Regardless of Trade Size
• Also Offers 50 Free Trades to Customers of optionsXpress and Other Brokerages

CHICAGO, Oct. 16, 2007 - OptionsHouse, Inc. ("OptionsHouse"), an online retail and institutional brokerage firm, today introduces its new $4.95 flat-rate commission on all stock trades, regardless of size. OptionsHouse had previously charged $9.95 per stock trade.

"OptionsHouse redefined retail options trading by offering a true flat rate of $9.95 per option trade, regardless of the size of the trade," said OptionsHouse Chief Executive Officer, John Hass. Escalating commission structures and pricing based on the number of times a customer trades remain standard in the industry among OptionsHouse competitors.

"We've had such positive feedback on our flat-rate options commission that we are continuing to innovate by introducing a new $4.95 flat-rate stock commission regardless of size," Hass said. "This is also an opportunity for us to deliver even greater value to our customers, given our declining execution costs."

"And we will not stop there, " Hass added. "We will continue to offer attractive margin rates and no hidden fees."

OptionsHouse Also Offers Free Trades to Customers of optionsXpress and Other Competing Brokerages

Also new, OptionsHouse is offering customers of optionsXpress and other competing brokerage firms 50 free trades if they open an account with OptionsHouse by the end of the year.

"Our competitor, optionsXpress helped to establish retail online options trading in the first part of this decade. It is our goal, however, to set the standard in the future," said Hass. "Our low flat rates, especially when compared to competitors' higher and escalating options commissions, together with our uniquely easy-to-use yet powerful online site, provides traders with an innovative and exceptional trading platform with low execution costs, making it arguably the best choice in the industry."
