ASX RELEASE

26 April 2021

DIRECTOR RESIGNATION

4DS Memory Limited (ASX:4DS) ( 4DS ) (the Company ), announces the resignation of Jim Dorrian (“Jim”) from the Board.

For personal reasons Jim has tendered his resignation effective today. The Company will not be making any additional comments surrounding the circumstances of Jim's resignation. It is a private and very personal matter.

The Company requests social media not to speculate on Jim’s resignation.

Jim, after some time and space, will make himself available as a consultant for strategic input if and when 4DS enters into commercialisation discussions.

Dr Guido Arnout commented “What 4DS has achieved to date is in large part thanks to Jim’s personal early-stage investment in 4DS combined with the experience Jim brought to the Board as successful entrepreneur and seasoned venture capitalist. Thanks Jim for your guidance and personal friendship.”

Executive Director David McAuliffe commented “In his venture capital career, Jim actively searched for investment opportunities that addressed global needs but at the same time were technically challenging. Jim saw these attributes in 4DS and his vision is evident in the data the Company has reported to date and the world class partners we have retained over many years. For over a decade Jim’s intellect has been an invaluable asset and I, the Board and shareholders thank him and his family. Jim remains a 4DS advocate and more importantly a friend.”

ENDS

Authorised for release by the Board.
