Update on Implementation
of Final Funding Agreement

James Hardie today provided an update on discussions with the NSW Government and Australian Taxation Office (ATO) aimed at resolving outstanding matters relating to the Final Funding Agreement (FFA) signed between James Hardie and the NSW Government in December 2005.

Since the ATO’s decision in late June to refuse to endorse the fund established for asbestos claimants as a charity, James Hardie has been involved in ongoing discussions with the NSW Government and ATO regarding the tax treatment of the Special Purpose Fund (SPF).

The company is currently in discussions with the NSW Government in relation to potential and limited amendments to the FFA and related agreements to achieve a satisfactory outcome for all stakeholders which would enable the substantive obligations agreed in the FFA to be implemented in full. The company is working in co-operation with the NSW Government and progress is being made towards achieving such an outcome.

The company has also held meetings with the ATO to seek fresh binding rulings in relation to the tax treatment of the SPF, once the proposed amendments have been agreed. The ATO has been co-operative and has indicated it will treat the determination of the tax treatment as a priority.

James Hardie and the NSW Government are devoting significant time and resources towards resolving these issues and there is goodwill among all stakeholders to removing any remaining barriers to the implementation of the FFA.

On the assumption that a satisfactory outcome is achieved with the NSW Government and the ATO confirms the parties’ understanding of the tax outcomes, the company expects an extraordinary general meeting of shareholders would be held within 10 weeks of an agreement being reached.

Work to satisfy the other conditions precedent to the FFA is well advanced, including the preparation of an independent expert’s report, an Explanatory Memorandum for shareholders, discussions with lenders and an updated actuarial report by KPMG Actuaries Pty Limited.

James Hardie has received indications that the MRCF currently has sufficient funds to pay asbestos claims until early 2007. James Hardie has begun investigating options for providing interim assistance to the MRCF to obtain funding if negotiations with the NSW Government and ATO are more protracted than is currently expected and, as a result, the existing funding available to the MRCF is exhausted before the FFA is implemented in full.
