Toronto Stock Exchange To Launch POSIT(Tm) Canada On Friday, April 5th,

Date 02/04/2002

The Toronto Stock Exchange Inc. (TSE) announced today that it will launch POSIT Canada, a non-attributed, electronic order-matching system for equity securities, as a facility of the Toronto Stock Exchange on Friday, April 5th, 2002.

POSIT Canada is being licensed from the POSIT Joint Venture, a joint venture between a subsidiary of Investment Technology Group (NYSE: ITG) and a subsidiary of Barra, Inc. (Nasdaq: BARZ). POSIT is the world's largest system for electronic matching of equities during the market day.

Initially, there will be two POSIT Canada matches per day at 10:30am and 2:30pm Eastern Time. Trades will be matched at the mid-point of the bid/ask spread. Institutions will be able to send their orders directly to POSIT Canada with zero information disclosure.

"The TSE recognizes the need to remain on the leading edge of innovation and is committed to a future of providing consistently high quality, competitively priced products and services," said Richard Nesbitt, President of TSE CDNX Markets Inc. "POSIT Canada is an example of this. It is another alternative trading feature for large investors. The TSE's continuous market is one of the most efficient in the world but there is a requirement from some investors for a deep and liquid call market. This initiative helps us achieve our goals of providing a Faster, Better and Cheaper marketplace for investors."

"The availability of POSIT Canada will allow institutions to trade larger blocks of stock with minimal market impact. We are pleased to be working with the Toronto Stock Exchange to bring this successful technology to the Canadian marketplace. This adds another market to the 12 countries ITG currently supports POSIT in," stated Raymond L. Killian, Jr., Chairman, President, and Chief Executive Officer of ITG.

*POSIT is a service mark of the POSIT Joint Venture, a joint venture between Barra POSIT, Inc., a subsidiary of Barra, Inc., and ITG Software, Inc., a subsidiary of ITG.
