                    (b)         is a condition subsequent; and

                    (c)         until the expiration of the offer period will
                                be for the benefit of Coeur d'Alene alone and

6.3                 Any contract resulting from acceptance of this Offer will
                    not become binding unless and until the condition in clause

6.5                 The breach or non-fulfillment of any of the conditions set
                    out in clause 6.1 does not, until the end of the offer
                    period, prevent a contract arising to acquire your Gasgoyne
                    Shares resulting from your acceptance of this Offer but, if

                    (c)         that condition has not been fulfilled,

                    all contracts resulting from the acceptance of Offers and
                    all acceptances that have not resulted in binding contracts
                    are void.

6.6                 Coeur d'Alene may at any time at its sole discretion but in
                    compliance with section 663(2) of the Corporations Law by
                    notice in writing to Gasgoyne declare the Offers free from

                    requirements.

7.4                 Where the requirements for acceptance have been complied
                    with in respect of some but not all of the Acceptance
                    Shares, Coeur d'Alene may in its sole discretion deem your
                    acceptance of this Offer complete in respect of those of
                    the Acceptance Shares for which the requirements have been
                    complied with (in this clause 7.4 referred to as "RELEVANT
                    SHARES") but not in respect of the remainder
                    notwithstanding any other terms of this Offer.  In that
                    event, Coeur d'Alene must provide the consideration in
                    respect of the Relevant Shares but not any other Acceptance
                    Shares you may hold, notwithstanding any other terms of

                    d'Alene Shares for your Gasgoyne Shares by reason of your
                    acceptance of this offer and you will be a "foreign
                    shareholder" for the purposes of this clause 12.  If you
                    are a foreign shareholder and you accept this Offer, Coeur
                    d'Alene will arrange for a nominee sale in accordance with
