Obligations of other persons
In addition to the person specified in Rule 9.1, each of the principal members of a group of persons acting in concert with that person may, according to the circumstances of the case, have the obligation to extend an offer.
NOTE ON RULE 9.2
Prime responsibility
The prime responsibility for making an offer under this Rule normally attaches to the person who makes the acquisition which imposes the obligation to make an offer. If such person is not a principal member of the group acting in concert, the obligation to make an offer may attach to the principal member or members and, in exceptional circumstances, to other members of the group acting in concert. This could include a member of the group who at the time when the obligation arises does not have any interest in shares. In this context, the Panel will not normally regard the underwriter of a mandatory offer, by virtue of the underwriting alone, as being a member of a group acting in concert and, therefore, responsible for making the offer (but see Note 3 on the definition of acting in concert).
An agreement between a person and a bank under which the person borrows money for the acquisition of shares or an interest in shares which gives rise to an obligation under the Rule will not of itself fall within the above.
