KENSEY NASH CORPORATION AND ORTHOVITA, INC. ANNOUNCE NEW AGREEMENTS TO JOINTLY DEVELOP SOFT TISSUE REPAIR PRODUCTS AND EXTEND CO-DEVELOPMENT RELATIONSHIP

March 3, 2005, EXTON, PA; MALVERN, PA -Kensey Nash Corporation (Nasdaq: KNSY) and Orthovita, Inc. (NASDAQ: VITA) today jointly announced they have expanded on their existing relationship and have agreed to pursue co-development of soft tissue repair products for orthopedics. In addition, the companies agreed to a lengthened term of their original co-development agreement signed in March 2003, which has led to the launching of four product lines in the last twelve months, with more products planned.

Similar to the terms of the original agreement, Kensey Nash will manufacture the new co-developed soft tissue products and Orthovita will market and sell the products worldwide through its focused biomaterials distribution channel, with Kensey Nash receiving a royalty on the net sales. The new products are expected to be available for launch in calendar year 2006 pending receipt of required regulatory clearances. In addition, the first agreement, under which the VITOSS FOAM products have been commercialized, has been extended until 2014.

“Our co-development activities with Orthovita have been very synergistic,” commented Joe Kaufmann, President and CEO of Kensey Nash Corporation. “With these new agreements, we are looking to build on the successful relationship we have already established with Orthovita, and to extend the clinical applications of our BioBlanket™ and other related soft tissue technologies. Orthovita’s distribution system, specializing in biomaterials products for the orthopedic sector, is unique in the industry. Their focus has been an important factor in the success of the co-developed VITOSS FOAM products launched to date,” he concluded.

“Orthovita continues to identify new clinical targets for biomaterials products in the orthopedic space,” said Antony Koblish, President and CEO of Orthovita. “Kensey Nash’s extensive development expertise, in combination with our own, has been very valuable for us quickly getting useful products to surgeons to meet their clinical needs. We are pleased to be able to expand and diversify our biomaterials franchise to include bone and now soft tissue management products.”

Additional terms of the new agreements were not disclosed.
