AMSTERDAM (Reuters) - Dutch technology company Prosus NV PRX.AS on Wednesday urged shareholders of Britain's Just Eat PLC JE.L to accept its unsolicited 4.9 billion pound ($6.3 billion) cash bid for the company by Dec. 10, and spurn an alternative offer as too risky.

“We believe that the Takeaway.com offer underestimates the substantial investment required in Just Eat to recapture market share and improve performance,” Prosus CEO Bob van Dijk said in a statement of the rival proposal.

Takeaway’s all-share offer, which is supported by Just Eat’s board, currently values Just Eat at around 4.7 billion pounds.
