The board of the Alternative Investment Market-listed company has proposed a plan for 3D to become an investment company. As part of the arrangement, £100,000 will be injected into CarieScan, which will be offloaded to a new company, owned by current 3D shareholders, for a nominal sum.
It replaces a delisting plan revealed on August 6.
If shareholders back the scheme, Mr Strang and one other will join the 3D board, and chairman David Snow and chief executive Graham Lay will quit.
The move comes after Mr Strang joined the board of Plus Markets, which used to operate the junior Plus Stock Exchange.
