Dear Petratherm Shareholder

Petratherm Limited Rights Issue

On 17 December 2015, Petratherm Limited ( Petratherm ) announced a two for five non-renounceable pro rata rights issue at an issue price of $0.003 per new Petratherm share ( Rights Issue ). Eligible shareholders registered as at 23 December 2015 will be entitled to participate in the Rights Issue in respect of the number of shares they are the registered shareholder of.

Petratherm has decided, pursuant to Listing Rule 7.7.1 of the ASX Listing Rules, that it is unreasonable to make the offer to shareholders who have a registered address in a country outside of Australia or New Zealand ( Excluded Shareholders ) having regard to:

• the small number of shareholders with addresses in these other countries;

• the number and value of the Petratherm shares they hold; and

• the cost to Petratherm of complying with the legal requirements and the requirements of the regulatory authorities in each of the other countries concerned.

We regret that the Rights Issue is therefore not able to be extended to Excluded Shareholders. Excluded Shareholders will not receive a copy of the Offer Booklet.

Should you have any queries, please contact the Company Secretary on +61 8 8133 5000.

Yours faithfully
