Mit dem Rückkaufsinserat vom 25. März 2021 (das Rückkaufsinserat) veröffentlichte Santhera Pharmaceuticals Holding AG ein Angebot zum Umtausch der ausstehenden CHF 60 Millionen 5%- Wandelanleihe mit Fälligkeit 2022 (die 2017/22 Wandelanleihe) nach den im Rückkaufsinserat aufgeführten Konditionen (das Umtauschangebot). Das Umtauschangebot wurde von Anleihensgläubigern in Bezug auf die 2017/22 Wandelobligationen mit einem Gesamtnennbetrag von CHF 44'845'000 angenommen, was 74.7% der sich im Umlauf befindlichen 2017/22 Wandelanleihe entspricht.

Vollzug

Santhera hat entschieden, das Umtauschangebot am 4. Mai 2021 zu vollziehen. Das Umtauschangebot wird über das Bankensystem abgewickelt. Mit dem Vollzug wird auf die Erfüllung aller Angebotsbedingungen (b), (c), (d) und (e), wie im Rückkaufsinserat definiert, die bis zu diesem Datum nicht erfüllt sind, verzichtet.

Inhaber von 2017/22 Wandelobligationen, die das Umtauschangebot nicht angenommen haben, bleiben Anleihensgläubiger gemäss den Bedingungen der 2017/22 Wandelanleihe.

Die Gesellschaft wird den Wandelpreis am 4. Mai 2021 bekannt geben. Die Abstimmung der Anleihensgläubiger über die Restrukturierung der 2017/22 Wandelanleihe, die der Anleihensgläubigerversammlung am 8.

The Company, certain affiliated companies and the nominees or brokers (acting as agents) may make certain purchases of, or arrangements to purchase, 2017/22 Bonds outside the Exchange Offer during the period in which the Exchange Offer remains open for acceptance.
