Kirchner and Company, Inc. acted as M&A Advisor to Nerites Corporation.

Exton, Pennsylvania 31 January 2011 – Kensey Nash Corporation (Nasdaq: KNSY), today announced it has acquired the assets of privately held Nerites Corporation, a developer of medical adhesives and anti-fouling coatings based in Madison, Wisconsin for $20 million in cash. Nerites is developing a technology platform of adhesive-based biomaterials which would allow Kensey Nash to further its penetration into the regenerative medicine markets encompassing soft tissue surgical repair, orthopaedics, sports medicine, spine and neurosurgery.

Surgical sealants and adhesives have applications in most surgical procedures. Over the past several years the wound closure market has shifted from early technology such as staples or sutures to next generation technologies as they have become available, including a variety of external and internal surgical adhesives. These products address a market that encompasses over 70 million surgical wounds in the U.S. alone. By 2015, the U.S. medical adhesive and sealant markets are projected to be over $1 billion.

In addition to possible new surgical sealant and adhesive products, Kensey Nash intends to develop and integrate the acquired adhesive, sealant, and coating technologies into its regenerative biomaterials business. The Company believes that access to this technology will enable the Company to develop a portfolio of next generation hybrid adhesive-based products that integrate its ECM, collagen and polymer technology platforms for applications in general, neurologic, plastic/reconstructive, orthopaedic, urologic, cardiovascular and thoracic surgical specialties. Initial product targets include devices for repairing defects in abdominal walls, dural membranes, and gastrointestinal tracts. Revenue from product sales is not expected for at least three to five years.

The Company also intends to explore applications of the Nerites anti-fouling technology for preventing bacterial biofilm formation. Biofilms form when microorganisms attach to implanted medical devices, forming a biological film coating which can interrupt the healing process and result in infection. It is estimated that device-related biofilm infections increase hospital stays and add over one billion dollars per year to U.S. hospitalization costs.

Though the accounting for this transaction has not been finalized, the Company currently expects to account for this transaction as an asset acquisition, with a significant portion of the purchase price expensed in the Company’s third quarter of fiscal 2011 as in-process research and development. The acquisition is expected to be dilutive to earnings by approximately $0.02 per share in the second half of fiscal 2011 (excluding any in-process R&D charges and acquisition costs). The Company currently expects that in fiscal 2012, the acquisition will have a neutral impact on earnings, as any R&D spending on the Nerites technology will be reallocated from other projects.

“We are very excited about this acquisition,” commented Joseph W. Kaufmann, President and CEO of Kensey Nash Corporation. “The Nerites’ technology will integrate well with Kensey Nash’s existing biomaterial capabilities and technologies, providing many opportunities for next generation products currently in the market and expanding our development pipeline as well as opportunities for additional strategic partnerships. We will initially target the hernia and dura repair markets,” he concluded.

“We are very pleased with this transaction and the commitment Kensey Nash is making to broadly commercialize products based on our technology,” commented Shaun C. Lonergan, President and CEO of Nerites Corporation. “We are proud of our Madison team and excited about the impact this technology can have on improving the practice of medicine. We believe the expertise and resources Kensey Nash brings to the table will really enhance that opportunity,” he added.

The Nerites’ technology is inspired by the proteins secreted by marine mussels for bonding to underwater surfaces. Research conducted on these adhesive proteins by Phillip Messersmith, Ph.D., of Northwestern University identified the key components believed to be primarily responsible for the adhesive properties. Synthetic versions of these key components have been developed to create biomaterials capable of binding to tissue and other materials in aqueous surgical environments. Nerites has funded their activities through $11 million from venture capital and private investors, as well as an additional $5 million in NIH and NSF Small Business Innovation Research (SBIR) grants.
