This event will mark the second phase of Pure Trading's market development that began with the provision of a cross printing facility on October 12, 2006.

This is the first visible alternative equity market in Canada and is the culmination of an industry wide effort over the course of more than a year. Pure Trading will initially offer trading services for three stocks (Fairfax Financial "FFH", Aber Diamonds "ABZ" and iSharesTM CDN Energy Sector Index Fund "XEG") and add to the list based on continuous consultation with service providers and participating dealers. The cross printing facility will only provide services for the three symbols supported in the continuous auction market.

The launch date has been chosen after extensive consultation with the trading community. The Pure Trading system is now fully ready and operational. Testing by the access vendors and dealers has progressed well, notwithstanding the strains on resources stemming from the current record trading and message traffic volumes in the industry. Based on this positive state of readiness, coupled with the timelines required for orderly system roll-outs to the trading desks, CNQ believes that the September 14th launch date will provide vendors and dealers with an opportunity to complete the remaining tasks required to begin trading in a multiple marketplace environment.

Market Hours
As previously announced, the hours of operation will be:

• 7am - pre-open session
• 9am - opening call with continuous trading until
• 5pm - market close (there will be no market on close session)

Pricing
Initial pricing during the launch period up to November 30, 2007, will remain unchanged:

1. Liquidity providers will be paid $.0031 per share for passive orders resulting in trades.
2. Liquidity takers will be charged a fee of $.0031 per share for active orders resulting in trades.
3. Crosses will be free of charge.
4. Trades in Canadian-listed rights, warrants and convertible debentures will be free of charge.

As previously announced, with respect to trading fees, CNQ will pay dealers the net amount in the event that the liquidity provision credit exceeds the liquidity removal charge.

Online Billing & Information Portal
CNQ is also delivering a dynamic web-based billing and information portal to assist dealers in managing their trading costs. There will be no additional charges for this service which is offered in a secure environment with daily updates on each dealer's activity down to the individual user level, as it reflects CNQ's continued commitment to deliver the superior service requested by the dealer community. Training on this system will commence next week.

Connectivity
Between now and August 28th, CNQ staff will be in contact with vendors and dealers to ensure that parties managing gateway connections to Pure Trading have the required agreements in place, have "certified" their gateway connections with CNQ Market Operations, and have finalized their request for production bundles.

All dealers will also have to ensure that they have made arrangements for the assignment of "Trader ID's" with CNQ and their access vendors.
