Furthermore, where the notes are placed solely with “qualified investors” and are then systematically resold on the secondary market at any time in the 12 months following such placing, purchasers of notes who are acting outside of the course of their business or profession may in certain circumstances be entitled to declare such purchase void and, in addition, to claim damages from any authorised person at whose premises the notes were purchased, unless an exemption provided for under Decree No. 58 applies.

#### Notice to Prospective Investors in Switzerland
The notes may not be publicly offered, directly or indirectly, in Switzerland within the meaning of the Swiss Financial Services Act (the “FinSA”) and will not be admitted to trading on any trading venue (exchange or multilateral trading facility) in Switzerland. Neither this prospectus supplement nor any other offering or marketing material relating to the notes constitutes a prospectus as such term is understood pursuant to the FinSA, and neither this prospectus supplement nor any other offering or marketing material relating to the notes may be publicly distributed or otherwise made publicly available in Switzerland.
