(1) In the case of a share acquisition agreement, each party to the agreement shall be taken (for purposes of the duty of disclosure) to be interested in all shares in the target company in which any other party to it is interested apart from the agreement (whether or not the interest of the other party in question was acquired, or includes any interest which was acquired, in pursuance of the agreement).

(2) For those purposes, and also for those of section 1057, an interest of a party to such an agreement in shares in the target company is an interest apart from the agreement if the party is interested in those shares otherwise than by virtue of the application of section 1055 and this section in relation to the agreement.

(3) Accordingly, any such interest of the person (apart from the agreement) includes for those purposes any interest treated as his or hers under section 1054 or by the application of section 1055 and this section in relation to any other agreement with respect to shares in the target company to which he or she is a party.
