Banco Santander or another person, including by means of a variation to the terms of the Notes to give effect to the exercise by the Relevant
Resolution Authority of such Bail-in Power. Each holder of the Notes further acknowledges and agrees that the rights of the holders of the Notes

For these purposes, a "Bail-in Power" means any statutory write-down and/or conversion power existing from time to time under any laws,
regulations, rules or requirements in effect in the Kingdom of Spain relating to the resolution of Regulated Entities applicable to Banco Santander

Resolution Mechanism and the Single Resolution Fund and amending Regulation (EU) No. 1093/2010 (as amended or superseded from time to
time, the "SRM Regulation") and (iii) the instruments, rules and standards created thereunder, pursuant to which any obligation of a Regulated
Entity (or an affiliate of such Regulated Entity) can be reduced, cancelled and/or converted into shares or other securities or obligations of such
Regulated Entity (or affiliate of such Regulated Entity) or any other person. A reference to "Regulated Entities" means any legal person to which
BRRD, as implemented in the Kingdom of Spain (including but not limited to, Law 11/2015, Royal Decree 1012/2015 and any other implementing

We do not undertake any obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future

IMPORTANT INFORMATION
MiFID II product governance / Professional investors and ECPs only target market--Solely for the purposes of each manufacturer's product
approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is eligible
counterparties and professional clients only, each as defined in MiFID II; and (ii) all channels for distribution of the Notes to eligible counterparties and
professional clients are appropriate. Any person subject to MiFID II subsequently offering, selling or recommending the Notes (a "distributor") should take
into consideration the manufacturers' target market assessment. However, a distributor subject to MiFID II is responsible for undertaking its own target
market assessment in respect of the Notes (by either adopting or refining the manufacturers' target market assessment) and determining appropriate
distribution channels.
PRIIPs Regulation / Prohibition of sales to EEA retail investors--the Notes are not intended to be offered, sold or otherwise made available to
and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area ("EEA"). For these purposes, a "retail
investor" means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of MiFID II; or (ii) a customer within the
meaning of Directive 2002/92/EC as amended, the Insurance Mediation Directive ("IMD"), where that customer would not qualify as a professional client
as defined in point (10) of Article 4(1) of MiFID II. Consequently no key information document required by Regulation (EU) No 1286/2014 (the "PRIIPs
Regulation") for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or
selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

of principal rank (i) pari passu among themselves and with any Senior Non Preferred
Liabilities, (ii) junior to the Senior Higher Priority Liabilities (and, accordingly, upon the
insolvency of Banco Santander, the claims in respect of the Notes will be met after
payment in full of the Senior Higher Priority Liabilities) and (iii) senior to any present and
future subordinated obligations (créditos subordinados) of Banco Santander in accordance
with Article 92 of the Spanish Insolvency Law.

Claims of holders of Notes in respect of interest accrued but unpaid as of the
commencement of any insolvency procedure in respect of Banco Santander shall constitute
subordinated claims (créditos subordinados) against Banco Santander ranking in
accordance with the provisions of Article 92.3º of the Spanish Insolvency Law and no
further interest shall accrue from the date of the declaration of insolvency of Banco
Santander.

The obligations of Banco Santander under the Notes are subject to the Bail-in Power.

"Senior Higher Priority Liabilities" means any obligations of Banco Santander which
specify their status as ordinary senior instruments and any other unsecured and
unsubordinated obligations (créditos ordinarios) of Banco Santander, other than the Senior
Non Preferred Liabilities.

"Senior Non Preferred Liabilities" means any unsubordinated and unsecured senior non
preferred obligations (créditos ordinarios no preferentes) of Banco Santander under
Additional Provision 14.2º of Law 11/2015, as amended by Royal Decree-Law 11/2017, of
23 June, on urgent measures in financial matters, and as further amended from time to time
(including any Notes), and any other obligations which, by law and/or by their terms, and to
the extent permitted by Spanish law, rank pari passu with the Senior Non Preferred
Liabilities.

Banco Santander agrees with respect to the Notes and each holder of the Notes, by his or

her acquisition of the Notes will be deemed to

have agreed to the ranking as described herein. Each such holder will be deemed to have
irrevocably waived his or her rights of priority which would otherwise be accorded to him
or her under the laws of Spain, to the extent necessary to effectuate the ranking provisions
of the Notes. In addition, each holder of the Notes by his or her acquisition of such Notes
authorizes and directs the Trustee on his or her behalf to take such action as may be
necessary or appropriate to effectuate the ranking of such Notes as provided in the
indenture dated as of April 11, 2017, as heretofore supplemented and amended (the "Base
Indenture") between us as Issuer and the Trustee and appoints the Trustee his or her
attorney-in-fact for any and all such purposes.

Banco Santander expects that upon insolvency, the payment obligations in respect of
principal under the Notes would rank pari passu with any obligations in respect of
principal of any second ranking senior securities issued by Banco Santander or any other
securities with the same ranking issued by Banco Santander.

As of December 31, 2017, Banco Santander had outstanding 21.01 billion of
unsubordinated indebtedness, including 11.13 billion of Senior Higher Priority Liabilities
and 9.87 billion of Senior Non Preferred Liabilities (including the second ranking senior
securities issued by Banco Santander prior to the entrance into force of Royal Decree-Law
11/2017).

Additionally, as of December 31, 2017, Banco Santander had outstanding 14.09 billion of
secured indebtedness and 15.36 billion of subordinated indebtedness. Banco Santander
subsidiaries had 103.56 billion indebtedness outstanding as of December 31, 2017.

Notes of such series offered by this prospectus supplement, will constitute a single series of
