    Section

Section 2.01, the Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders, the Guarantee Payments (except to the extent paid by the
Issuer), as and when due, regardless of any defense, right of set-off or
counterclaim which the Issuer may have or assert. This Guarantee is continuing,
irrevocable, unconditional and absolute.

    


    (b) Notwithstanding
Section 2.01(a), the Guarantor shall not be obligated to make any Guarantee
Payment in respect of Distributions (including accrued and unpaid Distributions
relating to the Redemption Price or Liquidation Distributions) on any Series 10
Preferred Securities if the aggregate of such Distribution, together with (a)
any other distributions previously paid during the then-current fiscal year
(defined as the accounting year of the Guarantor) and (b) any distributions
proposed to be paid during the then-current Distribution Period, in each case on
or in respect of Preferred Securities (including the Series 10 Preferred
Securities) would exceed the Distributable Profits of the immediately preceding
fiscal year. Moreover, even if Distributable Profits are sufficient, the
Guarantor shall not be obligated to make any payments hereunder to the extent
that, in accordance with applicable Spanish banking regulations relating to
capital adequacy requirements affecting financial institutions which fail to
meet their required capital ratios on a parent company only or on a consolidated
basis, the Guarantor would be prevented at such time from making payments on
Bank Shares or on Preferred Securities issued by the Guarantor.

    


    (c) Notwithstanding
Section 2.01(a), if, at the time that any Liquidation Distributions are to be
paid pursuant to this Guarantee in respect of each of the Series 10 Preferred
Securities, proceedings are pending or have been commenced for the voluntary or
involuntary liquidation, dissolution or winding up of the Guarantor or for a
reduction in the Guarantor’s shareholders’ equity pursuant to Article 169 of the
Spanish Corporations Act (Ley

    payable with respect to all other Preferred Securities, shall not
exceed the liquidation distributions that would have been payable from the
assets of the Guarantor (after payment in full in accordance with Spanish law of
all creditors of the Guarantor, including holders of its subordinated debt, but
excluding holders of any guarantee or other contractual right expressly ranking
equally with or junior to this Guarantee) had all the Preferred Securities been
issued by the Guarantor and ranked (i) junior to all liabilities of the
Guarantor, (ii) pari
passu with the most senior Preferred Securities which could have been
issued by the Guarantor (if any) and (iii) senior to the Bank Shares. In the
event of any such liquidation or winding-up of the Guarantor or a reduction in
its shareholders’ equity pursuant to Article 169 of the Spanish Corporations
Act, the Guarantor will exercise its voting rights in order to wind-up the
Issuer, subject to the prior consent of the Bank of Spain. In any such case,
Holders of Series 10 Preferred Securities right to receive liquidation
distributions will be limited as described above.

    


    (d) If
the payments described in Section 2.01(a) are not payable in full due to the
limitations referred to in Section 2.01(b) or (c), such amounts shall be made
pro rata among the
holders of Preferred Securities in the proportion that the amount available for
payment bears to the full amount that would have been payable, had there been no
such limitation.

    


    Section
2.02. The Guarantor
hereby waives notice of acceptance of this Guarantee and of any liability to
which it applies or may apply, presentment, demand for payment, protest, notice
of nonpayment, notice of dishonor, notice of redemption and all other notices
and demands.

    


    Section
2.03. The obligations,
covenants, agreements and duties of the Guarantor under this Guarantee shall in
no way be affected or impaired by reason of the occurrence from time to time of
any of the following:

    


    (a) the
release or waiver, by operation of law or otherwise, of the performance or
observance by the Issuer of any express or implied agreement, covenant, term or
condition relating to the Series 10 Preferred Securities to be performed or
observed by the Issuer;

    


    (b) the
extension of time for the payment by the Issuer of all or any portion of the
Distributions, Redemption Price, Liquidation Distributions or any other sums
payable under the terms of the Series 10 Preferred Securities or the extension
of time for the performance of any other obligation under, arising out of, or in
connection with, such Series 10 Preferred Securities;

    


    (c) any
failure, omission, delay or lack of diligence on the part of Holders to enforce,
assert or exercise any right, privilege, power or remedy conferred on the
Holders pursuant to the terms of the Series 10 Preferred Securities, or any
action on the part of the Issuer granting indulgence or extension of any
kind;

    (d) the voluntary or involuntary liquidation, dissolution, sale of any
collateral, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization, arrangement, composition or readjustment of debt of,
or other similar proceedings affecting, the Issuer or any of the assets of the
Issuer;

    


    
      (e)  any
invalidity of, or defect or deficiency in, the Series 10 Preferred Securities;
or

    

    


    (f) the
settlement or compromise of any obligation guaranteed hereby or hereby
incurred.

    


    There
shall be no obligation of the Holders to give notice to, or obtain consent of,
the Guarantor with respect to the happening of any of the
foregoing.

    


    Section
2.04. This is a
guarantee of payment and not of collection. A Holder may enforce this Guarantee
directly against the Guarantor, and the Guarantor waives any right or remedy to
require that any action be brought against the Issuer or any other person or
entity before proceeding against the Guarantor. Subject to Section 2.05, all
waivers herein contained shall be without prejudice to the Holders’ right at the
Holders’ option to proceed against the Issuer, whether by separate action or by
joinder. The Guarantor agrees that this Guarantee shall not be discharged except
by payment of the Guarantee Payments in full and by complete performance of all
obligations of the Guarantor under this Guarantee.

    


    Section
2.05. The Guarantor
shall be subrogated to all rights of the Holders against the Issuer in respect
of any amounts paid to such Holders by the Guarantor under this Guarantee and
shall have the right to waive payment of any amount of Distributions in respect
of which payment has been made to the Holders by the Guarantor pursuant to
Section 2.01; provided, however that the Guarantor shall not (except to the
extent required by mandatory provisions of law) exercise any rights which it may
acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of a payment under this Guarantee, if, at
the time of any such payment, any amounts are due and unpaid under this
Guarantee. If any amount on the Series 10 Preferred Securities is paid to the
Guarantor in violation of the preceding sentence, the Guarantor agrees to pay
such amount to the Holders.

    


    Section
2.06. Subject to
applicable law and regulations and the requirements of any stock exchange on
which the Series 10 Preferred Securities may at the time be listed, the
Guarantor, at its sole option, shall be entitled to purchase Series 10 Preferred
Securities from any Holder, as a whole but not in part, to the extent that the
Issuer may purchase any Series 10 Preferred Securities.

    


    Section
2.07. The Guarantor
acknowledges that its obligations hereunder are several and independent of the
obligations of the Issuer with respect to the Preferred Securities and that the
Guarantor shall be liable as principal and sole

    


    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

     

    debtor hereunder to make Guarantee Payments pursuant to the terms of
this Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (f), inclusive of Section 2.03 hereof.

    


    Section
2.08. The Guarantor
represents and warrants that, subject to applicable laws, its obligations
hereunder rank and will at all times rank (a) junior to all liabilities of the
Guarantor, including subordinated liabilities (other than any guarantee or
contractual right expressed to rank equally with or junior to this Guarantee),
(b) pari passu with the
most senior Preferred Securities which could have been issued by the Guarantor,
if any, and any obligations of the Guarantor under any guarantee issued by it
relating to any Preferred Securities issued by any Subsidiary and (c) senior to
the Bank Shares.

    


    Each
Holder by its acquisition of Series 10 Preferred Securities will be deemed
to waive all other priorities that Spanish law or regulations may confer at any
time including those arising under articles 92 and 158 of Law 22/2003 of 9 July
2003 (Ley Concursal),
if any.

    


    


    ARTICLE
3

    


    Section
3.01. The Guarantor
agrees not to issue any preferred securities or other securities equivalent to
preferred securities ranking senior to its obligations hereunder and agrees not
to guarantee payments on preferred securities of any direct or indirect
Subsidiary of the Guarantor if that guarantee would rank senior to this
Guarantee (including, without limitation, any guarantee that would provide a
priority of payment with respect to Distributable Profits) unless this Guarantee
is amended to give the Holders of Series 10 Preferred Securities such rights and
entitlements as are contained in or attached to such preferred securities or
securities equivalent to preferred securities or such other guarantee, so that
this Guarantee ranks equally with, and contains substantially equivalent rights
of priority on payment of Distributable Profits if any, as such preferred
securities or securities equivalent to preferred securities or other
guarantee.

    


    Section
3.02. The Guarantor
agrees that if any amount required to be paid pursuant to this Guarantee in
respect of a Distribution payable during the most recent Distribution Period has
not been paid, whether by reason of the limitations of Section 2.01(b) hereof or
otherwise, then (i) no dividends (other than in the form of the Bank Shares or
other shares of the Guarantor ranking junior to obligations of the Guarantor
under this Guarantee) will be declared or paid or set apart for payment, or (ii)
other distribution made, upon the Bank Shares or any other shares of the
Guarantor ranking junior to the obligations of the Guarantor under this
Guarantee, and (iii) the Guarantor will not redeem, repurchase or otherwise
acquire for any consideration (including any amounts to be paid or made
available for a sinking fund for redemption of any Bank Shares), Bank Shares or
any other shares of the Guarantor ranking junior to the obligations
of

    


    
      
        
        

      

      
        6

        
          

        

      

      
        
        

      

    

     

    the Guarantor under this Guarantee (except by conversion into or
exchange for shares of the Guarantor ranking junior to the obligations of the
Guarantor under this Guarantee), until such time as either the Issuer or the
Guarantor, pursuant to this Guarantee, shall have resumed the payment of, or set
aside payment with respect to, full Distributions on the Series 10 Preferred
Securities for four consecutive Distribution Periods.

    


    Section
3.03. The Guarantor
further agrees to maintain ownership of 100% of the ordinary shares of the
Issuer, directly or indirectly, as long as any Series 10 Preferred Securities
are outstanding and not to permit or take any action to cause the liquidation,
dissolution or winding-up of the Issuer except in the event of the liquidation,
dissolution or winding-up of the Bank or of a reduction in the Bank’s
shareholders’ equity pursuant to Article 169 of the Spanish Corporations Act
(Ley de Sociedades
Anónimas).

    


    


    ARTICLE
4

    


    This
Guarantee shall terminate and be of no further force and effect upon payment in
full of the Redemption Price of all outstanding Series 10 Preferred Securities,
upon purchase and cancellation of all Series 10 Preferred Securities, or upon
payment of the Liquidation Distributions and liquidation of the Issuer;
provided, however, that this Guarantee shall continue to be effective or shall
be reinstated (as the case may be) if at any time a Holder of a Series 10
Preferred Securities is required to restore payment of any sums paid on such
Series 10 Preferred Securities or under this Guarantee.

    


    


    ARTICLE
5

    


    Section
5.01. All guarantees
and agreements contained in this Guarantee shall bind the successors, assigns,
receivers, trustees and representatives of the Guarantor and shall inure to the
benefit of the Holders. The Guarantor shall not assign its obligations hereunder
without the prior approval of the Holders of not less than two-thirds in
liquidation preference of the outstanding Series 10 Preferred Securities or by
resolution adopted at a special general meeting of holders (Junta General Especial de
Partícipes) and approved by Holders of at least two-thirds of the
liquidation preference of the outstanding Series 10 Preferred Securities;
provided, however, that the foregoing shall not preclude the Guarantor from
merging or consolidating with, or transferring or otherwise assigning all or
substantially all of its assets to, a banking organization or any other entity
permitted by applicable laws without obtaining any approval of such
Holders.

    


    Section
5.02. Except for those
changes (a) required by Section 3.01 hereof, (b) which do not adversely affect
the rights of Holders or (c) necessary or

liquidation preference of the Series 10 Preferred Securities, or by a resolution
adopted at a special general meeting of holders (Junta General Especial de
Partícipes) and approved by Holders of not less than two-thirds in
liquidation preference of the outstanding Series 10 Preferred
Securities.
