Commitments and Contingencies

Note 21 — Commitments and Contingencies

The Company is prohibited from granting a security interest in certain of the Company’s patents and/or future royalty streams under the terms of the Series A and B Convertible Preferred stock.

Under the Company’s plan of reorganization upon emergence from bankruptcy in July 2002, the Series A Preferred stock and the dividends accrued thereon that existed prior to emergence from bankruptcy are to be exchanged into one share of new Common stock for every five shares of Series A Preferred stock held as of the date of emergence from bankruptcy. This exchange is contingent on the Company’s attaining aggregate gross revenues for four consecutive quarters of at least $10,000,000 and would result in the issuance of 325,000 shares of Common stock. Through December 31, 2011, the Company had not reached such aggregate revenue levels.

In conjunction with its FDA clearance, the Company agreed to conduct a post-market surveillance study to further analyze the safety profile of bovine thrombin as used in the AutoloGel^TM System. This study is estimated to cost between $500,000 and $700,000 over a period of several years, which began in the third quarter of 2008. As of December 31, 2011, approximately $350,000 had been incurred.

In July 2009, in satisfaction of a new Maryland law pertaining to Wholesale Distributor Permits, the Company established a Letter of Credit, in the amount of $50,000, naming the Maryland Board of Pharmacy as the beneficiary. This Letter of Credit serves as security for the performance by the Company of its obligations under applicable Maryland law regarding this permit and is collateralized by the CD described in Fair Value Measurements (see Note 5).

At December 31, 2011, we are committed to $321,000 in capital expenditures representing Angel® machines sufficient to address forecasted customer demand.
