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 OSullivan on (02) 8274 5265.
Yours faithfully,
