TELESTE EXPANDS CO-DETERMINATION NEGOTIATIONS

Due to the continued uncertain market situation Teleste expands the
co-determination negotiations in a manner, which, for some persons, may require
layoffs of over 90 days as well as redundancies of over 9 persons. The exact
number of employees and office workers who may be facing layoffs and
redundancies will be established in these co-determination negotiations. At the
first stage, the relevant measures are estimated to involve flexible layoffs.

The negotiations aim at finding solutions for adapting Teleste operations to the
difficult-to-predict market situation without endangering the company's good
growth opportunities.
