Dear Sir,

Request for Trading Halt

On behalf of James Hardie Industries plc (the company), I request a trading halt in all securities of James Hardie from 10.00am today, Wednesday, 17 April 2013.

In accordance with Listing Rule 17.1, I advise:

1. The company requests a trading halt pending an announcement containing details of legal action initiated by the New Zealand Ministry of Education against two New Zealand James Hardie subsidiaries and other parties.

2. The company requests that trading be halted from 10.00am until an announcement to the market is made by the company. The company expects to make an announcement later today.

3. The company would request that trading recommence immediately after the company has made an announcement regarding the legal action.

4. The company is not aware of any other reason why the trading halt should not be granted.

If you have any questions concerning the above please do not hesitate to contact Sean O’Sullivan on (02) 8274 5265.

Yours faithfully,
