Dear                ,

As you already know, we have launched an extraordinary variable remuneration scheme that will be take effect from 2013 (scheme Four). This new Scheme cancels and replaces the current Scheme Three.

Extraordinary variable remuneration is accrued only once, over the course of five years for the 2013-2017 period, and is not recurrent remuneration.

Its purpose is to reward completion of the personal objectives that have been set for you(*), based on achievement of the objectives defined in the Strategic Scheme, according to the criteria and formulas established for that purpose, to be paid to the people identified by the management.

These people must remain at the company until the end of this period, performing the duties that gave rise to their initial inclusion, except in the case of retirement or death, in which case the consolidated part of the scheme will be paid at the end of the period, provided that the conditions established for the accrual of the amount are met, which includes the requirement for the average price of Abengoa’s Class B shares to be no less than 4.48 euros during the last three months of 2017.

The amount is freely set by the management, in line with the professional circumstances and duties of each beneficiary.

In your case, this remuneration is: €«Euros», of which €«Euros» is considered to be consolidated.

Please would you send me the original copy of this letter, duly signed by yourself, to confirm your understanding and acceptance, which is a pre-requisite. The signature and date must be witnessed by a notary public or official witness in order for the document to be accepted as an original.
