A caution here. The wording in ADN's Bidder Statement says that "Andromeda may, subject to the Corporations Act, declare this Offer and all other Offers and all contracts resulting from the acceptance of Offers free from the conditions" (section 14.8 page 123) Seems as though they may intend to retain the right to hold acceptances even when when they vary the conditions but best to seek further clarification on this, since I am not attempting to give guidance. As to what the Corporations Act allows them to do, you will need to seek legal advice.
This matter is further commented on in the Target Statement with "Therefore, if any Condition is unsatisfied, Andromeda may elect to waive the Condition and proceed with the acquisition of Minotaur Shares under its Offer or allow the Offer to lapse with unsatisfied Conditions. Generally, Andromeda will not have to decide whether to proceed with the acquisition of Minotaur Shares under its Offer until the date that it is required to provide its notice of status of Conditions which, as outlined in section 3.10 of this Target’s Statement, can be postponed if the Offer Period is extended." (section 3.9 page 24).
