AUCyber's (ASX:CYB) board favored 5G Networks' (ASX:5GN) revised takeover offer over a recently lodged non-binding proposal from private IT services provider Interactive, according to a second supplementary target's statement filed with the Australian bourse on Friday.

The board said it does not consider Interactive's "highly conditional" offer of AU$0.165 per AUCyber share a superior proposal compared with 5G Network's bid of AU$0.135 per share.

It said the nature of Interactive's preferred offer structure of a scheme of arrangement is highly uncertain since 5G Network already owns 21.43% of AUCyber.

"A scheme of arrangement is a complex and lengthy process that would incur significant costs and commitment of Company resources, which would be detrimental to the Company in the circumstances," the statement read.

Interactive made the offer on Thursday.

5G Networks' shares were up over 1% in recent Friday trade.
