DIRECTIONS

(1) If there are a number of substantial holders with similar or related relevant interests (eg. a corporation and its related corporations, or the manager and trustee of an equity trust), the names could be included in an annexure to the form. If the relevant interests of a group of persons are essentially similar, they may be referred to throughout the form as a specifically named group if the membership of each group, with the names and addresses of members is clearly set out in paragraph 7 of the form.

(2) See the definition of "associate" in section 9 of the Corporations Act 2001.

(3) See the definition of "relevant interest" in sections 608 and 671B(7) of the Corporations Act 2001.

(4) The voting shares of a company constitute one class unless divided into separate classes.

(5) The total number of votes attached to all the voting shares in the company or voting interests in the scheme (if any) that the person or an associate has a relevant interest in.

(6) The person's votes divided by the total votes in the body corporate or scheme multiplied by 100.

(7) Include details of:

(a) any relevant agreement or other circumstances by which the relevant interest was acquired. If subsection 671B(4) applies, a copy of any document setting out the terms of any relevant agreement, and a statement by the person giving full and accurate details of any contract, scheme or arrangement, must accompany this form, together with a written statement certifying this contract, scheme or arrangement; and

(b) any qualification of the power of a person to exercise, control the exercise of, or influence the exercise of, the voting powers or disposal of the securities to which the relevant interest relates (indicating clearly the particular securities to which the qualification applies).

See the definition of "relevant agreement" in section 9 of the Corporations Act 2001.

(8) If the substantial holder is unable to determine the identity of the person (eg. if the relevant interest arises because of an option) write "unknown".

(9) Details of the consideration must include any and all benefits, money and other, that any person from whom a relevant interest was acquired has, or may, become entitled to receive in relation to that acquisition. Details must be included even if the benefit is conditional on the happening or not of a contingency. Details must be included of any benefit paid on behalf of the substantial holder or its associate in relation to the acquisitions, even if they are not paid directly to the person from whom the relevant interest was acquired.

Annexure A Ausbil Investment Management Limited ABN: 26 076 316 473

Relevant interest in: IGO LTD

Citicorp Nominees Pty Limited and various other custodians hold shares in the Company as custodian and for which Ausbil is either:

• The responsible entity or trustee of a pooled investment product such as managed investment schemes (funds); or
• The investment manager of Portfolios held for a number of institutional investors. The institutional investors are generally superannuation funds regulated under the Superannuation Industry Supervision Act 1993.

The holding of shares in the Company was acquired as part of a wide portfolio of Australian shares acquired for the Funds and Portfolios.

Ausbil and the Custodians may hold relevant interests due to the capacity of these entities to dispose of the shares in the Company.

Each investor in a fund owns an individual interest in the Fund’s assets; no investor directly owns any asset of the Fund. The unit holding of each Fund varies from time to time as clients enter and withdraw from the Funds. The various institutional investors with portfolios delegate the management of the Portfolios to Ausbil.
