5. Conversion rules and arrangements

   In the case of issues of fixed-income securities convertible into shares of the Company carried out in accordance with the previous sections and for the purposes of determining the terms, conditions and arrangements of the conversion, it is agreed to establish the following criteria:

   1. The securities issued pursuant to this resolution may be convertible and/or exchangeable, in whole or in part, into newly issued shares of the Company or exchangeable for extant shares of the Company, ordinary shares of any kind, in accordance with a fixed (determined or determinable) or variable conversion and/or exchange ratio; the Board of Directors is empowered to decide whether they are necessarily or voluntarily convertible and/or exchangeable, and if so, voluntarily, at the option of their holders or of the Company, with the periodicity and for the period established in the issue agreement and which may not exceed thirty (30) years from the corresponding date of issue. The Board of Directors may establish that the Company reserves the right to choose, at any time, between conversion into new Company shares or the delivery of existing Company shares, specifying the nature of the shares to be delivered at the time of conversion, and may even choose to deliver a combination of newly issued Company shares with pre-existing shares, always respecting equal treatment among all holders of securities that convert on the same date. The Company may also choose to pay an amount in cash in lieu of its obligation to deliver shares, in whole or in part.

   2. If the conversion and/or exchange ratio for Company shares is fixed, the convertible and/or exchangeable debentures or bonds will be valued at their nominal amount and the shares at the fixed exchange rate determined in the resolution of the Board of Directors, or at the exchange rate determinable on the date or dates indicated in the resolution of the Board of Directors itself and based on the stock market value of the Company's shares on the date(s) or period(s) taken as a reference in the same resolution. In any case, the share price may not be lower than the arithmetic average of the closing prices, the weighted average price or other reference for the listing of the Company's shares on the Continuous Market during the period to be determined by the Board of Directors, which may not be longer than three (3) months or less than three (3) days prior to (i) the date of the meeting of the Board of Directors which, using this delegated power, approves the issue of the securities, or (ii) a specific date between the announcement of the issue and the date of disbursement of the securities by the subscribers (both inclusive). Furthermore, a premium or, where appropriate, a discount may be established on said price per share, although, in the event of a discount on the price per share, it may not exceed 25% of the value of the shares taken as a reference in accordance with the above provisions.

   3. It may be agreed to issue the debentures or bonds with a variable conversion and/or exchange ratio. In this case, the price of the shares for the purposes of conversion and/or exchange shall be the arithmetic average of the closing prices, the weighted average price or other benchmark of the Company's shares on the

      Continuous Market for a period to be determined by the Board of Directors, not exceeding three (3) months and not less than three (3) days prior to the date of conversion and/or exchange, with a premium or, where appropriate, a discount on said price per share. The premium or discount may be different for each conversion and/or exchange date of each issue (or, where appropriate, each tranche of an issue), although in the event of a discount on the price per share, it may not exceed 25%. Notwithstanding the foregoing, under the terms decided by the Board, a minimum and/or maximum reference price of the shares may be established as limits for the purposes of their conversion and/or exchange.

   4. When conversion applies, the fractions of the share that may be delivered to the holder of the securities shall be rounded up in the manner determined by the Board of Directors and each holder may receive in cash, if so established by the Board of Directors, in the event of rounding by default, the difference that may occur in such a case.

   5. In no case may the value of the share for the purposes of the ratio of conversion of the debentures to shares be less than its nominal value. Furthermore, in accordance with the provisions of article 415 of the LSC, bonds may not be converted into shares when the nominal value of the former is lower than that of the latter.

   6. When approving an issue of convertible and/or exchangeable debentures or bonds under the authorisation contained in this resolution, the Board of Directors shall issue a report developing and specifying, based on the criteria described above, the terms, conditions and arrangements of the conversion specifically applicable to the aforementioned issue. This report shall be accompanied by the corresponding auditor's report referred to in article 414.2 of the LSC.

   The Board of Directors is delegated the power to develop and specify the terms, conditions and arrangements of the conversion and/or exchange established above and, in particular, to determine the time of the conversion and/or exchange, which may be limited to a period fixed in advance, the ownership of the right of conversion and/or exchange, which may for the Company itself or the holders of debentures and/or bonds, the form in which the bondholders will be compensated (which may be through conversion, exchange, delivery of an amount in cash or a combination of any of the above or even a mandatory conversion, for the specific determination of which the Board will be free to choose what it determines most appropriate, including at the time of execution) and, in general, any other elements or conditions that may be necessary or convenient to establish for each issue.

6. Terms, conditions and arrangements for exercising warrants and other similar securities

   In the case of warrants issues, the following shall apply:

   1. In the case of warrant issues, to which the provisions of the LSC for convertible debentures shall be applied by analogy, to determine the terms, conditions and arrangements for exercising them, the Board of Directors is empowered to determine, in the broadest terms, the criteria applicable to the exercise of the subscription or acquisition rights of Company shares or of shares of another company, whether or not it is a part of the Group, or a combination of any of them, derived from the securities of this class that are issued under the delegated power granted herein, applying in relation to such issues the criteria established in section 5 above, with such adaptations as may be necessary in order to make them compatible with the legal and financial rules that apply to this type of security.

   2. The above criteria shall apply, mutatis mutandi and to the extent applicable, in relation to the issue of fixed-income securities (or warrants) exchangeable into shares of other companies.

7. Capital increase

   The Board of Directors is delegated the power to increase the capital by issuing new ordinary shares in the amount necessary to meet the requests for conversion of the convertible securities issued under this resolution. This power is expressly conditional on the total of the share capital increases agreed by the Board of Directors, counting both those that are agreed in the exercise of the powers now delegated and those that may be agreed in accordance with other authorisations of the Meeting, not exceeding the limit of half of the current share capital provided for in article 297.1 b) in fine of the LSC, nor 10% of said total share capital in the event that the issuance of the convertible securities excludes the shareholders' pre-emptive subscription rights. This authorisation to increase the capital includes the issue and circulation of the shares representing the capital on one or more occasions that are necessary to carry out the conversion, as well as the rewording of the article relating to the amount of the capital and, where appropriate, to cancel part of said capital increase if it is not necessary for the conversion into shares.

8. Exclusion of the right of pre-emption

   The Board of Directors is expressly delegated, under Articles 417 and 511 of the LSC, the power to exclude, in whole or in part, the pre-emptive subscription right of shareholders in the issue of convertible debentures or bonds, warrants and other similar securities, which it may decide to carry out under this authorisation, when this is necessary or appropriate for the corporate interest. In any case, if it is decided to exercise the power conferred to eliminate the pre-emptive subscription right, the Council shall issue at the time of approving the issue and in accordance with the applicable regulations, a report detailing the specific reasons in the corporate interest that justify such measure, which shall be the subject of the relevant report of an independent expert in accordance with the provisions of Articles 414.2. 417.2 and 511 of the LSC.

Furthermore, it is expressly stated that the Company is subject to the rules that exist or may be issued in the future in terms of the Stock Exchanges or the markets where the securities issued under this delegated power will be traded and, especially, with regard to contracting, permanence and exclusion from trading.
