BANCA IMI S.p.A. (incorporated with limited liability in the Republic of Italy) STRUCTURED NOTE PROGRAMME

BASE PROSPECTUS BANCA IMI S.p.A. (incorporated with limited liability in the Republic of Italy) STRUCTURED NOTE PROGRAMME Under this Structured Note Programme (the Programme) Banca IMI S.p.A. (the Issuer) may from time to time issue notes in bearer or registered form (respectively, Bearer Notes and Registered Notes and, together, the Notes) denominated in any currency determined by the Issuer. For the purposes of Directive 2003/71/EC, as amended (which includes the amendments made by Directive 2010/73/EU to the extent that such amendments have been implemented in a relevant Member State of the European Economic Area) (the Prospectus Directive) and relevant implementing measures in Ireland, this document (the Base Prospectus) constitutes a base prospectus issued in compliance with the Prospectus Directive and relevant implementing measures in Ireland for the purpose of giving information with regard to the issue of the Notes under the Programme during the period of 12 months after the date hereof. The Base Prospectus has been approved by the Central Bank of Ireland, as competent authority under the Prospectus Directive. The Central Bank of Ireland only approves this Base Prospectus as meeting the requirements imposed under Irish and EU law pursuant to the Prospectus Directive. Such approval relates only to the Notes which are to be admitted to trading on the regulated market of the Irish Stock Exchange plc (the Irish Stock Exchange) or other regulated markets for the purposes of Directive 2004/39/EC (the Markets in Financial Instruments Directive) or which are to be offered to the public in a Member State of the European Economic Area. Application has been made to the Irish Stock Exchange for Notes issued under the Programme to be admitted to the official list (the Official List) and trading on its regulated market. The regulated market of the Irish Stock Exchange is a regulated market for the purposes of the Markets in Financial Instruments Directive. Notes may, in certain circumstances, also be admitted to the electronic order book for retail bonds (the ORB) of the London Stock Exchange plc (the London Stock Exchange). The Notes will be issued in such denominations as may be specified by the Issuer and indicated in the applicable Final Terms (as defined below) save that the minimum denomination of each Note admitted to trading on a European Economic Area exchange or offered to the public in a Member State of the European Economic Area in circumstances which require the publication of a prospectus under the Prospectus Directive will be 1,000 (or, if the Notes are denominated in a currency other than euro, the equivalent amount in such currency) or such other higher amount as may be allowed or required from time to time by the relevant central bank (or equivalent body) or any laws or regulations applicable to the relevant Specified Currency. Notice of the aggregate nominal amount of Notes, interest (if any) payable in respect of Notes, the issue price of Notes and any other terms and conditions which are applicable to each Tranche of Notes will be set out in a final terms document (the Final Terms) which, with respect to Notes listed on the Irish Stock Exchange, will be delivered to the Central Bank of Ireland on or before the date of issue of the Notes of such Tranche. The Programme provides that Notes may be listed or admitted to trading, as the case may be, on such other or further stock exchange(s) or markets as the Issuer may determine. The Issuer may also issue unlisted Notes and/or Notes not admitted to trading on any market. Notes may be issued on a continuing basis and may be distributed by way of private or public placement as specified in the applicable Final Terms. If the applicable Final Terms so specify, Notes may be distributed to one or more Managers (each a Manager). The Issuer has been rated Baa1 (long-term) and P-2 (short-term) with stable outlook by Moody's Italia S.r.l. (Moody's), BBB (long-term) and A-2 (short-term) with stable outlook by S&P Global Ratings Italy S.r.l. (S&P Global) and BBB (long-term) and F2 (shortterm) with stable outlook by Fitch Ratings Ltd. (Fitch). Each of Moody's, Standard & Poor's and Fitch is established in the European Union and is registered under the Regulation (EC) no. 1060/2009 (as amended) (the CRA Regulation). As such each of Moody's, Standard & Poor's and Fitch is included in the list of credit rating agencies published by the European Securities and Markets Authority on its website (at https://www.esma.europa.eu/supervision/credit-ratingagencies/risk) in accordance with the CRA Regulation. Notes issued under the Programme may be rated or unrated by any one or more of the rating agencies referred to above. Where a Tranche of Notes is rated, such rating will be specified in the applicable Final Terms. A credit rating is not a recommendation to buy, sell or hold securities and may be subject to suspension, reduction or withdrawal at any time by the assigning rating agency. Prospective purchasers of Notes should ensure that they understand the nature of the relevant Notes and the extent of their exposure to risks and that they consider the suitability of the relevant Notes as an investment in the light of their own circumstances and financial condition. It is the responsibility of prospective purchasers to ensure that they have sufficient knowledge, experience and professional advice to make their own legal, financial, tax, accounting and other business evaluation of the merits and risks of investing in the Notes and are not relying on the advice of the Issuer or, if relevant, any Manager in that regard. See "Risk Factors" on pages 33 to 61. IMPORTANT EEA RETAIL INVESTORS - If the Final Terms in respect of any Notes includes a legend entitled "Prohibition of Sales to EEA Retail Investors", the Notes are not intended, from 1 January 2018, to be offered, sold or otherwise made available to and, with effect from such date, 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 Directive 2014/65/EU ("MiFID II"); (ii) a customer within the meaning of Directive 2002/92/EC ("IMD"), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Directive. 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. If the applicable Final Terms specify that Condition 8(ii) is applicable, the Issuer is not obliged to gross up any payments in respect of the Notes and shall not be liable for or otherwise obliged to pay any tax, duty, withholding or other payment which may arise as a result of the ownership, transfer,

presentation and surrender for payment, or enforcement of any Note and all payments made by the Issuer shall be made subject to any such tax, duty, withholding or other payment which may be required to be made, paid, withheld or deducted. The Notes have not been and will not be registered under the U.S. Securities Act of 1933, as amended (the Securities Act), and may not be offered, delivered, or sold within the United States to, or for the account or benefit of, U.S. persons (as defined in regulation S under the Securities Act), except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. The Notes are being offered and sold outside the United States in reliance on Regulation S under the Securities Act. There will be no public offering of the Notes in the United States. See "Subscription and Sale". The Notes will be issued in bearer form or in registered form. See "Form of the Notes" for further description of the manner in which Notes will be issued. The date of this Base Prospectus is 15 December 2017.

The Bearer Notes are subject to U.S. tax law requirements and may not be offered, sold or delivered within the United States or its possessions or to United States persons, except in certain transactions permitted by U.S. Treasury regulations. Terms used in this paragraph have the meanings given to them by the U.S. Internal Revenue Code of 1986, as amended (the Code ), and the U.S. Treasury Regulations promulgated thereunder. IMPORTANT INFORMATION RELATING TO PUBLIC OFFERS OF NOTES WHERE THERE IS NO EXEMPTION FROM THE OBLIGATION UNDER THE PROSPECTUS DIRECTIVE TO PUBLISH A PROSPECTUS Restrictions on Public Offers of Notes in Relevant Member States where there is no exemption from the obligation under the Prospectus Directive to publish a prospectus. Certain Tranches of Notes with a denomination of less than 100,000 (or its equivalent in any other currency) may be offered in circumstances where there is no exemption from the obligation under the Prospectus Directive to publish a prospectus. Any such offer is referred to as a Public Offer. This Base Prospectus has been prepared on a basis that permits Public Offers of Notes in each Member State in relation to which the Issuer has given its consent, as specified in the applicable Final Terms (each specified Member State a Public Offer Jurisdiction and together the Public Offer Jurisdictions). Any person making or intending to make a Public Offer of Notes on the basis of this Base Prospectus must do so only with the Issuer's consent to use this Base Prospectus as provided under "Consent given in accordance with Article 3.2 of the Prospectus Directive (Retail Cascades)" and provided such person complies with the conditions attached to that consent. Save as provided above, neither the Issuer nor any Manager have authorised, nor do they authorise, the making of any Public Offer of Notes in circumstances in which an obligation arises for the Issuer or any Manager to publish or supplement a prospectus for such offer. Consent given in accordance with Article 3.2 of the Prospectus Directive (Retail Cascades) In the context of a Public Offer of such Notes, the Issuer accepts responsibility, in each of the Public Offer Jurisdictions, for the content of this Base Prospectus in relation to any person (an Investor) who acquires any Notes in a Public Offer made by any Manager or an Authorised Offeror (as defined below), where that offer is made during the Offer Period specified in the applicable Final Terms and provided that the conditions attached to the giving of consent for the use of this Base Prospectus are complied with. The consent and conditions attached to it are set out under "Consent" and "Common Conditions to Consent" below. None of the Issuer or any Manager makes any representation as to the compliance by an Authorised Offeror with any applicable conduct of business rules or other applicable regulatory or securities law requirements in relation to any Public Offer and none of the Issuer or any Manager has any responsibility or liability for the actions of that Authorised Offeror. Except in the circumstances set out in the following paragraph, the Issuer has not authorised the making of any Public Offer by any offeror and the Issuer has not consented to the use of this Base Prospectus by any other person in connection with any Public Offer of Notes. Any Public Offer made without the consent of the Issuer is unauthorised and neither the Issuer nor, for the avoidance of doubt, any Manager accepts any responsibility or liability in relation to such offer or for the actions of the persons making any such unauthorised offer. If, in the context of a Public Offer, an Investor is offered Notes by a person which is not an Authorised Offeror, the Investor should check with that person whether anyone is responsible for this Base Prospectus for the purposes of the relevant Public Offer and, if so, who that person is. If the Investor is in any doubt about whether it can rely on this Base Prospectus and/or who is responsible for its contents it should take legal advice. 4

The Issue Price will be determined by the Issuer in consultation with the relevant Manager at the time of the relevant Public Offer and will depend, amongst other things, on the interest rate applicable to the Notes and prevailing market conditions at that time. The Offer Price of such Notes will be the Issue Price or such other price as may be agreed between an Investor and the Authorised Offeror making the offer of the Notes to such Investor. Neither the Issuer or the relevant Manager(s) will be party to arrangements between an Investor and an Authorised Offeror, and the Investor will need to look to the relevant Authorised Offeror to confirm the price at which such Authorised Offeror is offering the Notes to such Investor. IMPORTANT INFORMATION RELATING TO THE USE OF THIS BASE PROSPECTUS AND OFFERS OF NOTES GENERALLY This Base Prospectus does not constitute an offer to sell or the solicitation of an offer to buy any Notes in any jurisdiction to any person to whom it is unlawful to make the offer or solicitation in such jurisdiction. The distribution of this Base Prospectus and the offer or sale of Notes may be restricted by law in certain jurisdictions. The Issuer does not represent that this Base Prospectus may be lawfully distributed, or that any Notes may be lawfully offered, in compliance with any applicable registration or other requirements in any such jurisdiction, or pursuant to an exemption available thereunder, or assume any responsibility for facilitating any such distribution or offering. In particular, unless specifically indicated to the contrary in the applicable Final Terms, no action has been taken by the Issuer which is intended to permit a public offering of any Notes in any jurisdiction or distribution of this document in any jurisdiction where action for that purpose is required. Accordingly, no Notes may be offered or sold, directly or indirectly, and neither this Base Prospectus nor any advertisement or other offering material may be distributed or published in any jurisdiction, except under circumstances that will result in compliance with any applicable laws and regulations. Persons into whose possession this Base Prospectus or any Notes may come must inform themselves about, and observe, any such restrictions on the distribution of this Base Prospectus and the offering and sale of Notes. In particular, there are restrictions on the distribution of this Base Prospectus and the offer or sale of Notes in the United States or its possessions, the European Economic Area (including the Republic of Italy, France, the United Kingdom, Spain, Ireland, the Czech Republic, Germany, Hungary, the Republic of Poland, the Slovak Republic, the Netherlands, the Republic of Slovenia, the Portuguese Republic, the Grand Duchy of Luxembourg, Belgium, Croatia, Denmark, Sweden, Austria, Cyprus, Greece, Malta) and Japan (see "Subscription and Sale" on page 267). This Base Prospectus has been prepared on the basis that, except to the extent sub-paragraph (ii) below may apply, any offer of Notes in any Member State of the European Economic Area which has implemented the Prospectus Directive (each, a Relevant Member State) will be made pursuant to an exemption under the Prospectus Directive, as implemented in that Relevant Member State, from the requirement to publish a prospectus for offers of Notes. Accordingly any person making or intending to make an offer in that Relevant Member State of Notes which are the subject of an offering contemplated in this Base Prospectus as completed by final terms in relation to the offer of those Notes may only do so (i) in circumstances in which no obligation arises for the Issuer or any Manager to publish a prospectus pursuant to Article 3 of the Prospectus Directive or publish a supplement to a prospectus pursuant to Article 16 of the Prospectus Directive, in each case, in relation to such offer, or (ii) if a prospectus for such offer has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State and (in either case) published, all in accordance with the Prospectus Directive, provided that any such prospectus has subsequently been completed by final terms which specify that offers may be made other than pursuant to Article 3(2) of the Prospectus Directive in that Relevant Member State, such offer is made in the period beginning and ending on the dates specified for such 10

purpose in such prospectus or final terms, as applicable and the Issuer has consented in writing to its use for the purpose of such offer. Except to the extent sub-paragraph (ii) above may apply, neither the Issuer nor any Manager has authorised, nor do they authorise, the making of any offer of Notes in circumstances in which an obligation arises for the Issuer or any Manager to publish or supplement a prospectus for such offer.
