TAXATION The section Taxation in France, as set out on page 251 of the Base Prospectus is deleted in its entirety and replaced with the following: "The descriptions below are intended as a basic summary of certain tax consequences in relation to the ownership of the Notes under current French law. Persons who are in any doubt as to their tax position should consult a professional tax adviser. Withholding tax Notes issued by Crédit Agricole Corporate and Investment Bank or Crédit Agricole CIB Financial Solutions Following the introduction of the French loi de finances rectificative pour 2009 n 3 (n 2009-1674 dated 30 December 2009) (the Law), payments of interest and other revenues made by Crédit Agricole Corporate and Investment Bank or Crédit Agricole CIB Financial Solutions, in each case as Issuer, with respect to Notes issued on or after 1 March 2010 (other than Notes (as described below) which are consolidated (assimilables for the purpose of French law) and form a single series with Notes issued prior to 1 March 2010 having the benefit of Article 131 quater of the French Code général des impôts) will not be subject to the withholding tax set out under Article 125 A III of the French Code général des impôts unless such payments are made outside France in a non-cooperative State or territory (Etat ou territoire non coopératif) within the meaning of Article 238-0 A of the French Code général des impôts (a Non-Cooperative State). If such payments under the Notes are made in a Non-Cooperative State, a 50 % withholding tax will be applicable (subject to certain exceptions and to the more favourable provisions of any applicable double tax treaty) by virtue of Article 125 A III of the French Code général des impôts. Furthermore, interest and other revenues on such Notes may no longer be deductible from the Issuer's taxable income, as from the fiscal years starting on or after 1 January 2011, if they are paid or accrued to persons established or domiciled in a Non-Cooperative State or paid in such a Non-Cooperative State. Under certain conditions, any such non-deductible interest and other revenues may be recharacterised as constructive dividends pursuant to Article 109 of the French Code général des impôts, in which case such non-deductible interest and other revenues may be subject to the withholding tax set out under Article 119 bis of the French Code général des impôts, at a rate of 25% or 50%. Notwithstanding the foregoing, the Law provides that neither the 50% withholding tax set out under Article 125 A III of the French Code général des impôts nor the non-deductibility will apply in respect of a particular issue of Notes if the relevant Issuer can prove that the principal purpose and effect of such issue of Notes was not that of allowing the payments of interest or other revenues to be made in a Non-Cooperative State (the Exception). Pursuant to the ruling (rescrit) n 2010/11 (FP and FE) of the French tax authorities dated 22 February 2010, an issue of Notes will benefit from the Exception without the relevant Issuer having to provide any proof of the purpose and effect of such issue of Notes, if such Notes are: (i) (ii) (iii) offered by means of a public offer within the meaning of Article L.411.1 of the French Code monétaire et financier or pursuant to an equivalent offer in a State other than a Non-Cooperative State. For this purpose, an equivalent offer means any offer requiring the registration or submission of an offer document by or with a foreign securities market authority; or admitted to trading on a regulated market or on a French or foreign multilateral securities trading system provided that such market or system is not located in a Non-Cooperative State, and the operation of such market is carried out by a market operator or an investment services provider, or by such other similar foreign entity, provided further that such market operator, investment services provider or entity is not located in a Non-Cooperative State; or admitted, at the time of their issue, to the clearing operations of a Relevant Clearing System (as defined in Condition 1.2). 5

All Notes issued by Crédit Agricole Corporate and Investment Bank or Crédit Agricole CIB Financial Solutions will be admitted upon issuance to the clearing operations of a Relevant Clearing System. Notes issued by Crédit Agricole Corporate and Investment Bank or Crédit Agricole CIB Financial Solutions before 1 March 2010 and Notes issued from 1 March 2010 which are consolidated (assimilables for the purpose of French law) with Notes issued before 1 March 2010 Payments of interest and other revenues made by Crédit Agricole Corporate and Investment Bank or Crédit Agricole CIB Financial Solutions, in each case as Issuer, with respect to Notes issued from 1 March 2010 and which are consolidated (assimilables for the purpose of French law) and form a single series with Notes issued before 1 March 2010 with the benefit of Article 131 quater of the French Code général des impôts, will be exempt from the withholding tax set out under Article 125 A III of the French Code général des impôts. Notes issued before 1 March 2010, whether denominated in Euro or in any other currency, and constituting obligations under French law, or titres de créances négociables within the meaning of rulings (rescrits) n 2007/59 (FP) and n 2009/23 (FP) of the French tax authorities dated 8 January 2008 and 7 April 2009, respectively, or other debt securities issued under French or foreign law and considered by the French tax authorities as falling into similar categories, are deemed to be issued outside the Republic of France for the purpose of Article 131 quater of the French Code Général des Impôts, in accordance with Circular 5 I-11-98 of the French tax authorities dated 30 September 1998 and the aforementioned rulings (rescrits) n 2007/59 (FP) and n 2009/23 (FP). In addition, interest and other revenues paid by the relevant Issuer on Notes issued from 1 March 2010 and which are to be consolidated (assimilables for the purpose of French law) and form a single series with Notes issued before 1 March 2010 will not be subject to the withholding tax set out in Article 119 bis of the French Code général des impôts solely on account of their being paid in a Non-Cooperative State or accrued or paid to persons established or domiciled in a Non- Cooperative State. EU Savings Directive The EC Council directive 2003/48/EC on the taxation of savings income has been implemented into French law under Article 242 ter of the French Code général des impôts." 6
