Lists submitted that do not meet the above requirements will be treated as not having been submitted.

The following procedure is carried out to elect the directors:

A) If at least one list obtains a number of votes representing at least 29% of the Company share capital entitled to vote at the ordinary shareholders’ meeting :

a) all the directors except one shall be taken from the list with the highest number of votes, in the progressive order in which they are shown on the list, b) the remaining director shall be taken from the minority list that has obtained the highest number of votes and is not connected in any way, even indirectly, with the shareholders who filed or voted the list that obtained the largest number of votes.

If the first two lists receive the same number of votes, an even number of Directors less one shall be drawn from each of the said lists, in the numerical sequence in which they are listed on the lists, and the remaining Director shall be drawn from the li st that obtained the third -highest number of votes and is not connected in any way, directly or indirectly, with the shareholders who filed or voted for the lists that received the highest number of votes.

When only two lists are submitted and they contain the same number of votes, the remaining Director will be the oldest candidate of those that have not already been taken from those lists;

(B) If none of the lists receives votes equal to at least 29% of the share capital with voting rights at ordinary shareholders’ meetings, the directors are taken from all the lists submitted as follows: the votes received by the lists will be divided successiv ely by progressive whole numbers from one up to the number of Directors to be elected. The resulting scores shall be assigned to the candidates of each list in consecutive order using the order in which they are included in the lists. The candidates are then included in a single decreasing order list, based on the scores given to each one. Those with the highest score are elected. If more than one c andidate has the same score, the one from the list that has not had any director elected from it or has had the smallest number of directors elected is taken.

Lists that do not obtain a vote percentage equal to at least half that set by the Bylaws for the submission of lists shall not be considered.

If the candidates elected in the manner described above do not ensure the necessary number of Directors belonging to the less represented gender or the minimum number of directors that must meet the independence requirements prescribed by law, depending on the number of members of the Board of Directors according to prevailing legislation, the candidate elected last in the numerical sequence in the list that received the highest number of votes shall be replaced by the first candidate, as appropriate, of the less represented gender and/or fulfilling the criteria of independence required by law not elected from the same list according to the numerical sequence.

This replacement procedure shall be continued until the composition of the Board of Directors complies with the applicable legislation.

If this procedure does not produce this result, substitution shall take place on the basis of a resolution adopted by a relative majority of the Shareholders’ Meeting, after candidates with the necessary requisites are placed in nomination.

Should no list be filed or accepted, the Shareholders' Meeting shall adopt resolutions with the majorities required by law, without complying with the above -mentioned procedure, in order in any case to ensure the presence of the necessary number of
