2. Purpose of the Increase: Repsol Flexible Dividend Program

The Capital Increase serves as an instrument to implement the shareholder-remuneration program named "Repsol Flexible Dividend", in substitution of the traditional payment of the 2014 final dividend. The purpose of this remuneration system, that was set up for first time by the Company in 2012, is to offer all the Company's shareholders the option, at their free choice, of receiving new paid-up shares of the Company, or an amount in cash by selling their free-of-charge allocation rights to the Company (if
they do not sell on the market), as explained herein below.

Translation of the original in Spanish. In case of any discrepancy, the Spanish version prevails


The "Repsol Flexible Dividend" program is similar to those programs implemented by other companies in IBEX-35. With it, the Company wants to offer its shareholders an alternative which, without affecting their right to receive the entire remuneration in cash if they so wish, gives them the possibility of receiving paid-up shares of the Company.
"Repsol Flexible Dividend" program works as follows. Each shareholder will receive a free-of-charge allocation right for every Repsol's share held on the date mentioned in paragraph 3.1 below. These rights will be listed and may be traded on the Spanish Stock Exchanges during a 16 calendar day period. Following the end of this period, the rights will be automatically converted into new Repsol's shares. Each shareholder may opt for one of the following alternatives:
(a) Not to sell their free-of-charge allocation rights. In this case, at the end of the trading period the shareholder will receive the corresponding number of new paid-up shares.
(b) To sell all or part of their free-of-charge allocation rights to the Company under the Purchase Commitment at a guaranteed fixed price, mentioned below in this document. Shareholders choosing this option would monetize their rights and would receive a remuneration in cash, as in previous years. The Purchase Commitment will only be applicable with respect to those rights freely received by the shareholders, not to those purchased or otherwise acquired on the market, and will be in force and may be accepted during such time, within the trading period of the rights, mentioned in paragraph 3.4 below.
(c) To sell all or part of their free-of-charge allocation rights on the market, during the trading period mentioned in paragraph 3.4 below. Shareholders choosing this option would also monetize their rights, although in this case they would not receive a guaranteed fixed price, as in option (b) above, but instead the consideration payable for the rights would depend on market conditions in general and the quotation price of those rights in particular.
In consideration of its own needs, Company's shareholders may combine any or all of the alternatives
mentioned above.
It should be noted in this regard that the alternatives receive different tax treatment. A summary of the transaction tax applicable regime in Spain can be found in paragraph 2.6 of the report by the Board of Directors on the proposal of resolution submitted to the Annual Shareholders' Meeting that were approved under items five and six on the Agenda, which is available on the Company's website (www.repsol.com). In any case, it should be borne in mind that the taxation of the different options related to the Capital Increase set out therein does not cover all possible tax consequences.
Consequently, shareholders are recommended to consult their tax advisers on the specific tax impact of the proposed operation and to pay attention to any changes or amendments that may be made in both

the laws in place at the date of this operation and the interpretation criteria, as well as the specific circumstances of each shareholder or holder of free-of-charge allocation rights.

3. Details of the offer 3.1. Number of free-of-charge allocation rights needed to receive a new share, maximum number of new shares to be issued and face value of the Capital Increase.

In application of the formulas approved by the Annual Shareholders' Meeting, the CEO has established the following terms of the Capital Increase:
(i) The number of free-of-charge allocation rights needed to receive one new share ("No. Rights per share") is 34. Free-of-charge allocation rights will be allocated to whom being entitled to receive them according to the accounting records of Sociedad de Gestión de los Sistemas de Registro, Compensación and Liquidación de Valores, S.A. Unipersonal (Iberclear) at 23:59 the day of publication of the Capital Increase in the Official Gazette of the Commercial Registry (Boletín Oficial del Registro Mercantil) - expected on June 17, 2015. Company's shareholders will receive a free-of-charge allocation right for each share in the Company that they hold at that time. Accordingly, the said shareholders shall be entitled to receive one new share for every 34 old shares that they hold on the mentioned date.
The mentioned "No. Rights per share" has been calculated as described below, taking into account that the number of Company shares at the date of this report is 1,374,694,217 ("NES").
No. Rights per share = NES / Provisional no. shares = 1,374,694,217 / 40,537,102 = 33.912 = 34 rights (rounded up);
where
"Provisional no. shares" = Amount of the Alternative Option / Share Price = 687,347,109 / 16.956
= 40,537,102 and
"Share Price" = 16.956 euro, is the arithmetic mean of the weighted average prices of the Company's share on the Madrid, Barcelona, Bilbao and Valencia Stock Exchanges over the five (5) trading sessions prior to the date of the agreement adopted by CEO to execute the Capital Increase (days 8, 9, 10, 11 and 12 of June 2015), rounded up or down to the nearest thousandth of a euro and, in the event of half a thousandth of a euro, rounded up to the nearest thousandth of a euro.
(ii) The maximum number of new shares to be issued in the Capital Increase ("MNNS") is 40,432,182 resulting from the formula approved by the Annual Shareholder's Meeting of Repsol, which is reproduced below, rounded down to the nearest whole number:

Translation of the original in Spanish. In case of any discrepancy, the Spanish version prevails


MNNS = NES / No. Rights per share = 1,374,694,217 / 34 = 40,432,182 new shares (rounded down to the nearest whole number)
where, "NES", "No. Rights per share" and "Share Price" have the meaning specified in paragraph
(i) above.
Notwithstanding, the final number of shares to be issued will depend on the number of shareholders who request to receive their remuneration in cash at the fixed price of the Company's undertaking to acquire rights.
Repsol will waive the rights acquired by virtue of the undertaking to acquire rights, so the capital would be increased only by the amount corresponding to the free-of-charge allocation rights not acquired by Repsol pursuant to this undertaking1. In any case, the final number of shares to be issued in the Capital Increase will be promptly publish in the official notice of the closing of the Capital Increase, which is scheduled for the next July 6, 2015.
(iii) Consequently, the face value amount of the Capital Increase is 40,432,182 euro. However, as already mentioned, the final amount of the share capital increase will be calculated by multiplying the number of final shares for 1 euro.
Due to the number of free-of-charge allocation rights required for the allocation of one new share (34, according to the previous calculations), multiplied by the maximum number of new shares to be issued (40,432,182, according to the previous calculations), is 1,374,694,188 (lower than the number of shares in circulation (1,374,694,217), Repsol has waived a number of free-of-charge allocation rights equal to the difference between the two figures (29 rights) for the sole purpose of ensuring that the maximum number of new shares to be issued is a whole number and not a fraction.

3.2. Price of the purchase commitment of free-of-charge allocation rights

The guaranteed fixed price of Repsol's purchase commitment of rights (the "Purchase Commitment") is
0.484 euro gross per right, which results from the following formula of the Capital Increase:
Purchase Price = Share Price / (No. Rights per share + 1) = / (16.956 / (34+ 1) = 0.4844 = 0.484 (rounded up or down to the nearest thousandth of a euro and, in the event of half a thousandth of a euro, rounded up to the nearest thousandth of a euro).
Accordingly, shareholders who wish to receive their remuneration in cash, may sell their rights to Repsol at a guaranteed fixed price of 0.484 euro gross.

1 Also, if the final number of shares to be issued (i.e, the number of outstanding rights at the end of the trading period divided into the number of rights needed to receive one new share) is not a whole number, the Company will waive the number of rights required to that end.
