This summary does not address the tax treatment of the ADS, ordinary shares, contingent convertible preferred securities, senior notes, senior non-preferrednotes or subordinated notes on or following any exercise of the Spanish Bail-inPower with respect to such securities. A “U.S. Holder” is a person that for U.S. federal income tax purposes is a beneficial owner of ordinary shares, ADSs, contingent convertible preferred securities, senior notes, senior non-preferrednotes or subordinated notes, as applicable, and is:
