* The theoretical, (or gross), number of voting rights is used as the basis for calculating the crossing of thresholds : it includes voting rights stripped from shares that do not have the right to vote (own controlled shares, liquidity contract, etc...).

The by-laws of Vallourec contain a provision imposing an obligation to declare crossing thresholds in addition to those relating to legal thresholds.

This information is also available on the Vallourec website under "Capital & shareholding" or "information réglementée": http://www.vallourec.com/FR/group/FINANCE/Pag...tions.aspx
