SIRONA BIOCHEM APPOINTS GERMAN PRIVATE BANK HAUCK & AUFHAUSER AS DESIGNATED SPONSOR FOR XETRA(R)

Sirona Biochem Corp.'s shares have been accepted for continuous trading on the German electronic trading platform Xetra under the ticker symbol ZSB.DE. The international security identification number (ISIN) is CA82967M1005.

The electronic trading system Xetra is utilized to trade approximately 300,000 international instruments. Xetra has a market share of over 90 per cent in equity trading and is one of the fastest trading systems in the world with a round-trip time of only two milliseconds. Financial institutions, securities trading houses and brokers can participate in Xetra trading. Xetra operates independently of the trader's location, permitting international participation. In fact, more than 130 participants from European countries outside Germany trade on Xetra.

Sirona Biochem has appointed Hauck & Aufhauser Privatbankiers KGaA (H&A) as its designated sponsor on Xetra. The designated sponsor will work to facilitate higher liquidity in stock trading of Sirona common shares by maintaining a constant quotation volume (minimum trade volume) to ensure tradability is guaranteed -- even in highly volatile market periods.

Dr. Howard Verrico, chief executive officer and chairman of Sirona Biochem, stated: "The Xetra listing marks a further step in Sirona's commitment to its shareholders to enhance the liquidity of the company's common shares and is one of many initiatives we are taking to further increase market awareness. A generally visible valuation discount due to limited liquidity will be reduced and therefore should generate an increased interest of institutional investors. Several potential European investors have confirmed that a continuous Xetra listing will make it easier for them to invest in Sirona. We are proud that, from our point of view, the best Xetra specialist team in Germany has chosen Sirona as a new client."
