3.2 Rules of preference between proxy, long-distance vote and presence at General Meeting

3.2.1 Priorities between proxy, long-distance vote and physical attendance

(i) Personal attendance at a Extraordinary General Shareholders’ Meeting by a shareholder who had previously delegated or voted long distance, no matter the means used to cast the vote, shall render the said proxy or vote null and void.

(ii) Furthermore, a vote, no matter the means used to cast it, shall render ineffective any electronic proxy or proxy by printed card, even if previous, which shall deemed to be revoked, or subsequent, which shall be deemed not to have taken place.

3.2.2 Priorities between proxies

In the event that a shareholder validly makes several proxy delegations, the last one received by the Company shall prevail.

3.2.3 Priorities between long-distance votes

Any shareholder may validly vote long distance only once in relation to each position of securities. In the event that a shareholder makes several long-distance votes with respect to the same shares, whether electronically or by postal mail, the vote first received by the Company shall prevail, and any votes received on a subsequent date shall be invalid. A revocation or modification of that long-distance vote shall require the personal attendance of the shareholder at the Extraordinary General Shareholders’ Meeting.

3.3 Specificity of long-distance vote

A shareholder who wishes to vote by distance (through electronic means or postal mail) must indicate the specific direction of his or her vote for each one of the items included on the Agenda. If, in relation to any of the Agenda items, he or she does not specify the direction of his or her vote, he or she shall be deemed to have voted in favor of the proposals of the Board of Directors on the business included on the Agenda as formulated by the latter, and against the further proposed resolutions included in the supplement to the agenda formulated, as the case may be, in accordance with article 97.3 of the Spanish Corporations Law (“Ley de Sociedades Anónimas”).

3.4 Other Provisions

In the event that electronic means are employed, only one electronic action per each type of operation (one vote and one proxy) may be utilized.

Both a long-distance proxy as well as a vote shall remain null and void as a consequence of the disposal of the shares which entitle attendance of which the Company becomes aware.

The shareholder is exclusively responsible for the custody of his electronic signature in order to vote or delegate a proxy electronically.

3.5 Special Rules

Shareholders that are legal entities and those not resident in Spain must consult with the Shareholder Relations Line 900 666 900 the possibility, as the case may be, of adapting, with proper guarantees, the long-distance voting and proxy mechanisms to their peculiarities.

Furthermore, in the event that the shareholder is a legal entity, the latter must notify the Company of any change or revocation in the powers held by its representative and, therefore, Endesa declines any liability until such notification takes place.

4. TECHNICAL INCIDENTS

Endesa reserves the right to modify, suspend, cancel or restrict the electronic voting and proxy mechanisms when so required for technical or security reasons.

Endesa shall not be liable for any damages which may be caused to a shareholder arising out of breakdowns, overloads, dropped lines, failed connections, malfunctioning of postal service or any other eventuality of a like or similar nature, removed from the will of Endesa, which prevent the use of the long-distance voting and proxy mechanisms.
