First half operating income rose by 14% on a comparable structure of
consolidation and by 18.4% on a reported basis.  Net profit was up 14.1% on a
comparable structure of consolidation and 12.7% on a reported basis.
Consolidated sales and profits are now both subject to greater seasonal
variations than before, due to the seasonal nature of businesses at Lapeyre
Deutschland, ERG and Okfens.

In the second half, sales are expected to maintain the same pace of growth as in
the first half, and consoldiated net profit is expected, at least, to track
sales growth.
