 Ten CDIs will represent an interest in one share of our common stock. Holders of CDIs will not hold the legal title to the underlying shares of our common stock to which the CDIs relate, as the legal title will be held by the Depositary Nominee. Each holder of CDIs will, however, have a beneficial interest in the underlying shares in our common stock. Each holder of CDIs that elects to vote at a stockholders meeting will be entitled to one vote for every 10 CDIs held by such holder. In order to vote at a stockholder meeting, a CDI holder may:

| • |     | instruct the Depositary Nominee, as legal owner of the shares of common stock, to vote the common stock                                                                                                                                                  
 represented by their CDIs to vote the shares of our common stock represented by their CDIs in a particular manner. A voting instruction form will be sent to holders of CDIs and must be completed and returned to the share registry for the CDIs prior 
 to a record date fixed for the relevant meeting, or the Voting Instruction Receipt Time, which is notified to CDI holders in the voting instructions included in a notice of meeting;                                                                    |

| • |     | inform us that they wish to appoint themselves or a third party as the Depositary Nominee’s proxy with 
 respect to our shares of common stock underlying the holder’s CDIs for the purposes of attending and   |

| voting at the meeting. The instruction form must be completed and returned to the share registry for the CDI prior to the CDI Voting Instruction Receipt Time; or |

| • |     | convert their CDIs into shares of our common stock and vote those shares at the meeting. The conversion must be                                                                                                                                           
 undertaken prior to a record date fixed by the Board for determining the entitlement of members to attend and vote at the meeting. If the holder later wishes to sell their investment on the ASX, it would first be necessary to convert those shares of 
 common stock back to CDIs. Further details on the conversion process are set out below.                                                                                                                                                                   |

Voting instruction forms and details of these alternatives are included in each notice of meeting sent to CDI holders by the Company. Conversion of CDIs to shares of Common Stock CDI holders may at any time convert their CDIs to a holding of shares of common stock by instructing the share registry for the CDIs, either:

| • |     | Directly in the case of CDIs held on the issuer sponsored sub-register
