RELEVANT FACT

On May 14, 2007, the Board of Directors of the Company resolved to convene the Annual General Shareholders’ Meeting, to be held in Madrid, at pavilion no. 10 of the convention center named Parque Ferial Juan Carlos I (IFEMA), on June 20, 2007, at 11:00 a.m. in first call. In the event that the General Meeting cannot be held in first call because the necessary quorum is not achieved, it will be held in the same place and at the same time on June 21, 2007, in second call.

AGENDA

ONE. Examination and approval, as the case may be, of the annual accounts (balance sheet, income statement and annual report) and of the management report of the Company and its consolidated group for the fiscal year ending December 31, 2006, as well as of the corporate management during said fiscal year.

TWO. Application of fiscal year earnings and dividend distribution.

THREE. Appointment of the Auditor for the Company and its Consolidated Group.

FOUR. Authorization for the Company and its subsidiaries to be able to acquire treasury stock in accordance with the provisions of article 75 and additional provision one of the Spanish Corporations Law (“Ley de Sociedades Anónimas”).

SIX. Appointment of a Company Director.

SEVEN. Appointment of a Company Director.

EIGHT. Authorization to the Board of Directors for the execution and implementation may be, of the resolutions adopted by the General Meeting, as well as to substitute the authorities it receives from the General meeting, and granting of authorities for processing the said resolutions as a public instrument, registration thereof and, as the case may be, correction thereof.
