According to newswire Bloomberg, Dongfeng Motor Group, has offered $350m for an 85% stake in Fisker. Newswire Reuters said the company was favouring Geely's bid.

Opera, which has arranged $100m in working capital, will pay $50m in cash after the deal closes.

Laird said it would pay $1, with potential cash earn-out payments based on a multiple of 0.4 times revenue over a four-year period from 2014 up to a maximum of $60m if $150m in revenue is achieved.

In December, Consert said it was in advanced talks with undisclosed potential buyers for an acquisition before the end of the year, according to news provider CleanTech Group.

In March 2007, Cylex raised $20.5m in its series C round from Siemens Venture Capital, the corporate venturing unit of the eponymous Germany-based industrial conglomerate, and co-leaders Channel Medical Partners and Canaan Partners, which are both venture capital firms.
