17 In his affidavit of 20 May 2004 Mr Pallister deposes that he told the plaintiff that AD Engineering Pty Ltd had been involved to develop a prototype of the Mobilert technology on the basis of "the existing patents", and that $340,000 was required to make payment to AD Engineering Pty Ltd. Mr Pallister deposes that the plaintiff said words to the effect "How much do you want to sell 50% of your shareholding in Mobilert International Ltd", and Mr Pallister said that he said that the price would be $US650,000. Mr Pallister says that Mr Morgan asked him whether Mr Pallister would consent to "us" (presumably Mr Morgan and Mr Barany) securing a right to participate in the purchase of the shares by providing payment of $AU340,000 to use to pay AD Engineering Pty Ltd so that the development of the prototype could be continued. Mr Pallister said that he used words to the effect that the funds were needed immediately, that $340,000 would be sufficient in the short term, and that "if you advance us those monies (sic) you can have an option as to whether or not you wish to proceed with the purchase of the shares" in "Mobilert International" by paying the total purchase price of $US650,000. Mr Pallister further deposes that he told the plaintiff and Mr Barany that if they were prepared to make the initial payment of $340,000, then once they had thought about the matter and if they decided to proceed with the purchase of the shares, they were to notify him and, upon payment of the balance, the shares would be transferred to the plaintiff. Mr Pallister said that he told them that if they decided not to proceed with the transfer of the shares, then he should be notified and then "we will need some time to refund your investment". He said that if there were to be a refund of the moneys it would not be until the production of the alarm system had begun and sales achieved.
