and will be redeemed on the date on which a winding up, dissolution or liquidation of the Issuer (otherwise than for the purpose of a solvent amalgamation, merger or reconstruction under which the assets and liabilities
of the Issuer are assumed by the entity resulting from such amalgamation, merger or reconstruction and such entity assumes the obligations of the Issuer in respect of the Securities in accordance with Condition 13.2) is

administrative authority, or (ii) any resolution passed at a shareholders' meeting of the Issuer or (iii) any provision which is set out in the by-laws of the Issuer from time to time (including the maturity of the Issuer
which, as of the Issue Date, is set in its by-laws at 31 December 2100). Upon having become due and payable according to the provisions above, the Securities will be redeemed at an amount equal to their principal

Issuer may redeem all, but not some only, of the relevant Securities on any Call Date at their principal amount together with any interest accrued up to, but excluding, the applicable Call Date and any outstanding Arrears
of Interest. The Issuer may also redeem all, but not some only, of the relevant Securities at the applicable Early Redemption Price at any time upon the occurrence of a Withholding Tax Event, an Accounting Event, a
Rating Methodology Event or a Tax Deductibility Event (each as defined in the relevant Terms and Conditions of the Securities). The Issuer may redeem all (but not some only) of the NC 6.5 Securities on any day prior
to 8 June 2027 (the date falling 3 months before the NC 6.5 Securities First Reset Date) at the Make-whole Redemption Amount (as defined in the Terms and Conditions of the NC 6.5 Securities). The Issuer may redeem
all (but not some only) of the NC 9.5 Securities on any day prior to 8 June 2030 (the date falling 3 months before the NC 9.5 Securities First Reset Date) at the Make-whole Redemption Amount (as defined in the Terms
and Conditions of the NC 9.5 Securities). In the event that at least 75 per cent. of the aggregate principal amount of the relevant Securities issued on the Issue Date has been purchased by or on behalf of the Issuer or a
Subsidiary (as defined in the relevant Terms and Conditions of the Securities) and cancelled, the Issuer may redeem all, but not some only, of the outstanding Securities at the applicable Early Redemption Price. See

Redemption and Purchase Purchases and Substantial Repurchase Event" in respect of the NC 9.5 Securities.
If at any time after the Issue Date the Issuer determines that a Withholding Tax Event, Tax Deductibility Event, Rating Methodology Event or an Accounting Event has occurred and is continuing, and has provided the
Trustee with the relevant certificate and opinion or, in the case of Condition 6.5 only, the Rating Agency Confirmation pursuant to Conditions 6.3, 6.4, 6.5 or 6.6 (as applicable), then the Issuer may, without any
requirement for the consent or approval of the relevant Securityholders or relevant Couponholders and subject to the pre-conditions set out in Condition 7.2, (i) exchange the relevant Securities or (ii) vary the terms of
the Securities, so that after such exchange or variation the Securities remain or become, as the case may be, eligible for the same or (from the perspective of the Issuer) more favourable tax, accounting or ratings treatment
than the treatment to which they were entitled prior to the relevant event occurring. See "Terms and Conditions of the NC 6.5 Securities Exchange or Variation upon a Withholding Tax Event, Tax Deductibility Event,
Rating Methodology Event or Accounting Event and Preconditions to such Exchange or Variation" in respect of the NC 6.5 Securities and "Terms and Conditions of the NC 9.5 Securities Exchange or Variation upon
a Withholding Tax Event, Tax Deductibility Event, Rating Methodology Event or Accounting Event and Preconditions to such Exchange or Variation" in respect of the NC 9.5 Securities.

senior only to the Issuer's payment obligations in respect of any Junior Securities (each as defined in the relevant Terms and Conditions of the Securities). The Securities will constitute obbligazioni pursuant to Article
2410 et seq. of the Italian Civil Code. The Securities will not be guaranteed.

Paying Agent and the Agent Bank accordingly disclaims all and any liability whether arising in tort or contract
or otherwise which it might otherwise have in respect of this Offering Circular or any such statement.
No person is or has been authorised by the Issuer to give any information or to make any representation not
contained in or not consistent with this Offering Circular or any other information supplied in connection with
the offering of the Securities and, if given or made, such information or representation must not be relied upon
as having been authorised by the Issuer, any of the Joint Lead Managers or the Trustee.
Other than in relation to the documents which are deemed to be incorporated by reference (see "Documents
Incorporated by Reference"), the information on the websites to which this Prospectus refers does not form part
of this Prospectus and has not been scrutinised or approved by the Central Bank.
Neither this Offering Circular nor any other information supplied in connection with the offering of the
Securities (a) is intended to provide the basis of any credit or other evaluation or (b) should be considered as a
recommendation by the Issuer, any of the Joint Lead Managers or the Trustee that any recipient of this Offering
Circular or any other information supplied in connection with the offering of the Securities should purchase any
Securities. Each investor contemplating purchasing any Securities should make its own independent
investigation of the financial condition and affairs, and its own appraisal of the creditworthiness, of the Issuer.
Neither the delivery of this Offering Circular nor the offering, sale or delivery of any Securities shall in any
circumstances imply that the information contained herein concerning the Issuer is correct at any time
subsequent to the date hereof or that any other information supplied in connection with the offering of the
Securities is correct as of any time subsequent to the date indicated in the document containing the same. The
Joint Lead Managers and the Trustee expressly do not undertake to review the financial condition or affairs of
the Issuer during the life of the Securities or to advise any investor in the Securities of any information coming
to their attention.

the Securities in any jurisdiction to any person to whom it is unlawful to make the offer or solicitation in such
jurisdiction. The distribution of this Offering Circular and the offer or sale of the Securities may be restricted
by law in certain jurisdictions. None of the Issuer, the Joint Lead Managers or the Trustee represents that this

iii

with any applicable registration or other requirements in any such jurisdiction, or pursuant to an exemption
available thereunder, or assumes any responsibility for facilitating any such distribution or offering. In
particular, no action has been taken by the Issuer, the Joint Lead Managers or the Trustee that would permit a
public offering of the Securities or the distribution of this Offering Circular in any jurisdiction where action for
that purpose is required. Accordingly, no Securities may be offered or sold, directly or indirectly, and neither
this Offering Circular 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 Offering Circular or any Securities may come must inform themselves about,
and observe, any such restrictions on the distribution of this Offering Circular and the offering and sale of the
Securities. In particular, there are restrictions on the distribution of this Offering Circular and the offer or sale
of the Securities in the EEA, the United States, the United Kingdom and the Republic of Italy. See "Subscription
and Sale".
Each potential investor in the Securities must determine the suitability of that investment in light of its own
circumstances. In particular, each potential investor should:
(a)
have sufficient knowledge and experience to make a meaningful evaluation of the Securities, the merits

and risks of investing in the Securities and the information included in this Offering Circular or any
applicable supplement;
(b)
have access to, and knowledge of, appropriate analytical tools to evaluate, in the context of its particular

financial situation, an investment in the Securities and the impact the Securities will have on its overall
investment portfolio;
(c)
have sufficient financial resources and liquidity to bear all of the risks of an investment in the Securities,

including where the currency for principal and interest payments is different from the potential investor's
currency;
(d)
understand thoroughly the terms of the Securities and be familiar with the behaviour of any relevant

financial markets; and
(e)
be able to evaluate (either alone or with the help of a financial adviser) possible scenarios for economic,

interest rate and other factors that may affect its investment and its ability to bear the applicable risks.
The Securities are complex financial instruments. Sophisticated institutional investors generally do not purchase
complex financial instruments as stand-alone investments. They purchase complex financial instruments as a
way to reduce risk or enhance yield with an understood, measured, appropriate addition of risk to their overall
portfolios. A potential investor should not invest in the Securities unless it has the expertise (either alone or with
a financial adviser) to evaluate how the Securities will perform under changing conditions, the resulting effects
on the value of the Securities and the impact this investment will have on the potential investor's overall
investment portfolio.
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 Securities (as defined herein) has led to the conclusion that: (i) the target market for the Securities is
eligible counterparties and professional clients only, each as defined in Directive 2014/65/EU, as amended
and supplemented ("MiFID II"); and (ii) all channels for distribution of the Securities to eligible
counterparties and professional clients are appropriate. Any person subsequently offering, selling or
recommending the Securities (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 Securities (by either adopting or refining the manufacturers'
target market assessment) and determining appropriate distribution channels.
UK MiFIR 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 Securities has led to the conclusion that: (i) the target market for the Securities is only eligible
iv

counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook ("COBS"), and
professional clients, as defined in the UK MiFIR; and (ii) all channels for distribution of the Securities to
eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling
or recommending the Securities (a "distributor") should take into consideration the manufacturer/s'
target market assessment; however, a distributor subject to the FCA Handbook Product Intervention
and Product Governance Sourcebook (the "UK MiFIR Product Governance Rules") is responsible for
undertaking its own target market assessment in respect of the Bonds (by either adopting or refining the
manufacturers' target market assessment) and determining appropriate distribution channels.
PRIIPS REGULATION / PROHIBITION OF SALES TO EEA The Securities 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 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 (EU) 2016/97 (as amended, the "Insurance Distribution Directive"), 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 (as amended,
the "PRIIPs Regulation") for offering or selling the Securities or otherwise making them available to
retail investors in the EEA has been prepared and therefore offering or selling the Securities or otherwise
making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

PROHIBITION OF SALES TO UK RETAIL INVESTORS The Securities 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 United Kingdom ("UK"). For these purposes, a retail investor means a person
who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No
2017/565 as it forms part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018
("EUWA"); or (ii) a customer within the meaning of the provisions of the FSMA and any rules or
regulations made under the FSMA to implement the Insurance Distribution Directive, where that
customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation
(EU) No 600/2014 as it forms part of UK domestic law by virtue of the EUWA. Consequently no key
information document required by Regulation (EU) No 1286/2014 as it forms part of UK domestic law
by virtue of the EUWA (the "UK PRIIPs Regulation") for offering or selling the Securities or otherwise
making them available to retail investors in the UK has been prepared and therefore offering or selling
the Securities or otherwise making them available to any retail investor in the UK may be unlawful under
the UK PRIIPs Regulation.
