Ann: AnteoTech secures $1.4m Qld Grant Funding, page-69

I'm wondering what was the agreement for Anteo undertaking the optimisation of the EV companies High Silicon anode, how much was / is this worth to the EV company and where is Anteo's income for this?
When a company requistations something, I've found normally that is done via a Purchase Order with agreed terms and pricing - and this is done up front.
So where is the agreement or at a minimum the income for this - is this what the potential commercial agreement that is mentioned in Anteo's timeline for - and if so why is it an agreement in arrears (after the delivery) rather than upfront?.
There must have been some agreement between Anteo and the EV company for Anteo to undertake this work - the AnteoX part is different I can understand that that is more of a testing nature and the EV company has paid $60k for AnteoX product - but when a company requisitions you to undertake work, you have to think that there is a fee involved and terms and milestones (eg Anteo says it delivered the anode on time - so they must have been some kind of agreement, which contained timelines)
