Additonally, Imagination Technologies Group, an existing shareholder in both firms, has pre-funded 7digital by way of a £1m bridging loan, which will be converted into new shares at the placing price on admission.The move comes as part of its previously announced plan to build a balanced business around its interactive assets.UBC's Chief Executive Simon Cole, said: "This transaction will create a world leading digital music and radio platform that is ideally positioned to exploit the convergence of radio and digital music services. The new business will also be well-placed to drive consolidation of the fragmented B2B digital music industry.
