In connection with this opinion, we have also examined and relied upon originals or copies of, certified or otherwise identified to our satisfaction, the following: 1. The Registration Statement; 2. The Second Amended and Restated Certificate of Incorporation of the Company; 3. The Amended and Restated By-Laws of the Company; 4. Resolutions duly adopted by the Board of Directors of the Company relating to the adoption of the Stock Option Plan, the Incentive Compensation Plan and the Settlement Plan; 2 Kensey Nash Corporation May 16, 1996 Page 2 5. The Stock Option Plan, the Incentive Compensation Plan and the Settlement Plan; 6. Certificates of public officials, certificates of officers, representatives and agents of the Company, and we have assumed that all of the representations contained therein are accurate and complete; and 7.
