SHARE CAPITAL

Article 6  Registered
Capital

The share capital is  2,506,080,598 (two billion five hundred six million eighty
thousand five hundred and ninety-eight euros).

It is divided into 1,253,040,299 shares each having a par value of
2, of the same class, fully paid.

Article 7  Form of shares

The shares are registered or bearer shares, according to the shareholders choice, under the conditions established by applicable legal provisions.



---

The company may apply legislative and regulatory provisions concerning the identification of holders of securities giving
them the immediate or future right to vote.

Any individual or entity, acting individually or jointly, who acquires a number of shares representing a proportion of
the capital or of voting rights equal to or exceeding 1% of the share capital, or any multiple of this percentage, even beyond the minimum declaration limits laid down by the legal and regulatory provisions, must inform the company of the total
number of shares and voting rights held by the individual or entity and also of any securities giving future access to the capital or voting rights which may potentially be attached. Notification is to be made by registered mail, return receipt
requested, within five stock exchange days of the date on which the threshold was reached.

The obligation to notify the company also applies when the
shareholders holding of the capital or voting rights falls to a level below each of those thresholds described in the third paragraph of this article.

The
legal penalties applicable to failure to declare the crossing of a statutory threshold apply equally to a failure to declare the crossing of any threshold stipulated in the articles of association and recorded in the minutes of the
shareholders meeting at the request of one or more shareholders holding at least 5% of the companys share capital or voting rights.

|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2) | Whenever it is necessary to possess a certain number of shares to exercise a right, the owners who do not possess that number of shares are responsible for taking any steps to combine the number required.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3) | Each shareholder has as many votes as the number of shares he owns or represents subject to the provisions below.
|-- | -----------------------------------------------------------------------------------------------------------------

at least two years.
