         Tenaris Announces the Loss of Roberto Rocca, Chairman


    LUXEMBOURG--(BUSINESS WIRE)--June 10, 2003--Tenaris S.A. (NYSE:TS)
(BASE:TS) (BMV:TS) (MTA Italy:TEN) announces, with great regret, the
death of Roberto Rocca, the chairman of the board of directors of
Tenaris and the honorary chairman of San Faustin N.V. (Tenaris's
controlling shareholder).
    Roberto Rocca was born in 1922 and was the head of the Techint
group of companies (that includes Tenaris), an international group of
companies with operations in the steel, energy, infrastructure,
engineering, construction and public service sectors. Mr. Rocca's
leadership, tireless spirit and creative vision were the inspiration
behind the strength and worldwide reach of the Techint group of
companies.
    San Faustin confirmed that no changes in the strategies, policies
or conduct of Tenaris's business are envisaged. The board of directors
of Tenaris will determine, in due course, Mr. Rocca's successor as
chairman of the board.
    Tenaris is a leading global manufacturer of seamless steel pipe
products and provider of pipe handling, stocking and distribution
services to the oil and gas, energy and mechanical industries and a
leading regional supplier of welded steel pipes for gas pipelines in
South America. Organized in Luxembourg, it has pipe manufacturing
facilities in Argentina, Brazil, Canada, Italy, Japan, Mexico and
Venezuela and a network of customer service centers present in over 20
countries worldwide.
