COMPAGNIE GENERALE DE GEOPHYSIQUE COMPLETES
ACQUISITION OF GEOSCIENCE CORPORATION.
Paris, France--December 13, 1999-- Compagnie Generale de Geophysique
(Paris RM: 12016) (NYSE:GGY NEWS) announced today that, through Sercel
Acquisition Corp., renamed Syntron Corporation, a wholly-owned subsidiary of
Sercel, Inc., it had completed its $6.71 per share cash tender offer for the
outstanding common shares of GeoScience Corporation (NASDAQ:GSCI - NEWS). Sercel
has accepted for payment 9,414,263, or approximately 94.3% of the outstanding
GeoScience shares.
The tender offer was made pursuant to a merger agreement between CGG and
GeoScience Corporation. Under the merger agreement, the remaining GeoScience
shares will be converted in a merger into the right to receive the $6.71 per
share cash amount paid in the tender offer. Sercel intends to complete the
merger of GeoScience into a Sercel subsidiary today.
GeoScience Corporation, based in Houston, Singapore and the United
Kingdom, employs 360 people, and is, through its subsidiary Syntron, Inc., a
leader in the area of marine seismic data acquisition equipment (in both surface
and seabed environments).
Based in Nantes (France), Sercel S.A. is present in the United States
through Sercel, Inc. (Houston), which is one of the leading manufacturers of
land seismic data acquisition equipment. As a result of the merger, Sercel will
be the direct parent of GeoScience. The union of Sercel and GeoScience-Syntron,
owing to the complementary nature of their products, makes the combined company
one of the world's largest producers of seismic equipment, with a complete range
of state-of-the-art products.
