##### 



Act 2006 and words or expressions used in this Agreement in relation to RTL shall
bear the same meanings as in the Corporations Act.(iv)
    
    In this Agreement unless the context otherwise requires references to Clauses
and paragraphs shall be construed as references to Clauses and paragraphs of this
Agreement respectively.(v)
    
    References to resolutions of the holders of Publicly-held Shares of either RTL

limitation, a resolution to appoint or remove an individual as a director of RTP, to
appoint or remove the auditors of RTP or to receive and adopt the accounts of RTP
would, if no resolution considering such matters in relation to RTL were put to the RTP
general meeting, be the equivalent resolution to a resolution relating to the
appointment or removal of the same individual as a director of RTL, the appointment or
removal of the same international firm of auditors as RTLs auditors or the receipt or
adoption of RTLs accounts as the case may be and references to a meeting of RTL
considering equivalent matters to those considered at a meeting of RTP shall be
similarly construed.(viii)
    
    References to the votes attaching to non Publicly-held Shares being disregarded in
respect of any resolution shall mean that the resolution in question would have been
duly passed (or not passed as the case may be) if the votes attaching to the non
Publicly-held Shares had not been cast.
 (C)
    
    The Clause headings are inserted herein only for convenience and shall not affect the
construction hereof.

by the matter and by an equivalent resolution of the other company, each by the same majority
(i.e. both by ordinary or both by special resolution) to separate meetings of the shareholders
of both RTL and RTP, whether or not such approval is required by law, the rules of any
relevant stock exchange or otherwise.2.2
    
    Each of RTL and RTP agrees with the other, RTAH and RTP Shareholder SVC that, if a
matter requires a Joint Decision, it shall do all acts and things necessary to ensure that the

    RTL agrees with RTP, RTAH and RTP Shareholder SVC that any poll on which the RTL

RTP has not been held and such votes counted by the beginning of the relevant RTL

Parallel General Meeting of RTP (other than those cast by Excluded RTP Holders or by
persons on whom a notice has been served under Article 145D of the RTL Memorandum and

    RTAH shall procure that Tinto Holdings Australia exercises the votes on the
