MARKETS INC. IMPLEMENTS STRIDE TO POWER CANADIAN ELECTRONIC MARKET

- Supports Efficiency and Anonymity in Canadian Block Trading

NEW YORK, JUNE 15, 2005 -- Headstrong, Inc., a premier global consultancy and
financial solutions company, announced today that Toronto-based MARKETS Inc. has implemented STRIDE, Headstrong’s exchange and electronic matching engine, to power its BlockBook™ electronic trading network.

BlockBook™ is an innovative network for block trading in Canadian equities. This new electronic marketplace masks the size and value of the investor’s intentions while they monitor the market for trading opportunities at the best possible match.

The firm’s patent pending trading methodology is based on in-depth study and
knowledge of dealing and trading patterns and is designed to improve the efficiency of the upstairs market. The benefits of the system include more choice in trading methodologies, reduction of trading costs and improved liquidity.

STRIDE was designed to provide unique and efficient trade flow and execution
mechanisms, which create and enable marketplaces and participants. STRIDE
powers electronic markets, exchanges and alternative trading systems throughout Asia, Europe and North America.

"As the global financial markets focus on efficiency, anonymity, liquidity and cost, new and innovative electronic trading models are evolving. The introduction of BlockBookâ„¢ is an excellent example," said Greg Johnston, Director, Headstrong Financial Products. "STRIDE was a perfect fit for MARKETS Inc. because of its flexibility to accommodate leading edge electronic trading strategies on top of its proven electronic matching engine."

"By implementing STRIDE, we are able to deploy our leading-edge models for
progressive disclosure and follow-on auctions. This will stem the flow of pre-trade information and improve the way the institutional market operates," said Karl Abbott, Chief Technology Officer, MARKETS Inc.

Sandeep Sahai, Managing Director, Headstrong, Inc., commented, "The ability to
deploy world-class trading technology so quickly and easily for MARKETS Inc. is testimony to the STRIDE architecture and Headstrong’s global breadth."
