Tenaris has set up a Compliance Line for investors to communicate
their concerns directly to independent directors. Communications
may be confidential or anonymous, and may be submitted in writing
through our Shareholder's Compliance Line.
All such communications shall be promptly reviewed by our chief
audit executive, and any concerns relating to accounting, internal
controls, auditing or officer conduct shall be sent immediately
to the chair of the audit committee.
All concerns will be reviewed and addressed by our chief audit executive
in the same way that other concerns are addressed by the company.
The status of all outstanding concerns addressed to the independent
directors or the audit committee will be reported to the chair of
the audit committee on a quarterly basis.
