In the most ambitious move yet by a Korean company into the US mass computer market, Daewoo Telecom Co Ltd has reached agreement in principle to acquire its US distributor, the bankrupt Leading Edge Products Inc, Needham Heights, Massachusetts. It says it will either pay creditors a part of their claims at once, with no further liability to them, or pay them dollar for dollar over time. Other firms reportedly looking at Leading Edge were Philips NV and Televideo Systems Inc.
