AndaGen AG Completes Successful Financial Restructuring

Eliminates over four million Euros in debt from balance sheet

San Antonio, Texas and Hanover, Germany - May 4, 2009 - AdnaGen AG announced today the completion of its debt restructuring efforts.

AdnaGen AG, developer and marketer of blood test diagnostics kits for the identification and molecular analysis of circulating tumor cells, substantially reduced its debt by exchanging €4.2 million of debt and related accrued interest for equity. This event is a significant milestone in completing the financial turn-around and corporate renewal for AdnaGen. OncoVista, Inc., AdnaGen’s 95% majority shareholder, together with financial investors Technologie-Beteiligungs-Gesellschaft mbH, Mittelstandische Beteilgungsgesellschaft Niedersachsen and Biomed Venture GmbH joined forces to position AdnaGen with the ability to secure additional financing to support the Company’s growth strategy

This event provides a structure for AdnaGen to proceed with a potential road show and raise additional capital.

Alexander Weis, CEO and Chairman of OncoVista, Inc., took control of AdnaGen’s management and operations as of February 2009 in order to orchestrate the turnaround.

Dr. Weis stated: “Since January 2009, we have gained new customers in labs and clinics resulting in a tripling of monthly sales of AdnaGen products within one financial quarter. This financial turnaround has been a challenge; however its successful completion demonstrates the renewed trust in AdnaGen’s business potential as well as in the flexibility of our investors. Having achieved this debt restructuring, we can now concentrate on moving forward to fully optimize AdnaGen operations, achieve mid-term cash break-even and gain new investors for our current financing round. We strongly believe that patients, physicians, our business partners and investors will all benefit from this and future successes.”
