A Responsible Care® re-verification for Degussa Canada Inc.’s Gibbons,
Alberta, was carried out on April 26th and 27th, 2005 by a three-member
Canadian Chemical Producers’ Association (CCPA) appointed Team,
augmented by a local community representative.

This reverification team found that the Responsible Care ethic as it pertains to internal environmental,
health and safety issues is well understood and entrenched in the company’s EH&S management system.
To a very large degree it guides the daily actions and decisions of the company’s management team and
its employees. It is the company’s externalization of Responsible Care, the “Being Seen To Be Doing
The Right Thing”, that gives the team concern. We do, as always, also see opportunities for
improvement elsewhere in the company’s management system. These will also be mentioned in the text
of the report.

On Tuesday April 11, 2005 two reverification team members met with the
Ashland Canada Corp. Vice-President Faisal Zekry and Responsible Care®
coordinator David Kim to review the status of the findings requiring action from
the January 2001 report and subsequent return visit reports.

The Nexen Chemical division is a member of the C.C.P.A. and their various chemical facilities had received Responsible Care® reverification to the 2002-2005 Responsible Care® protocol. As a unique corporate objective in 2002 Nexen Inc., the parent company, chose to apply the Responsible Care® codes and ethic to the oil and gas division and requested an in-place verification of the Balzac, Alberta gas processing facility. This facility received verification in January 2003. As a continuing commitment to Responsible Care® the company requested an in-place verification of their petroleum facilities in the Republic of Yemen, Canadian Nexen Petroleum Yemen (C.N.P.Y.). To be included in the verification were the seismic and drilling process, crude processing facility, a 130 kilometer pipeline and a crude shipping terminal at Ash Shihr on the Gulf of Aden. As a result of the Balzac verification the team had a good understanding of the process flow from the initial seismic exploration through to final product shipment; however, process flow charts, facility pictures and descriptions and the responses to the 151 code element questions provided an excellent base for understanding the Yemen operations.

Cytec Canada Inc., Responsible Care® re-verification was conducted on February 1 &
2, 2005 by a team appointed by the Canadian Chemical Producers’ Association
(CCPA).

The re-verification was held at the company’s only Canadian site located at Niagara
Falls, Ontario. The Plant, Laboratories and Offices are located on a large land site of
some 750 acres which is secured by 4-miles of fencing.
