Note 8 – Commitments and Contingencies

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 were 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 was contingent on the Company’s attaining aggregate gross revenues for four consecutive quarters of at least $10,000,000 and if met would result in the issuance of 325,000 shares of the Company’s common stock. The Company reached such aggregate revenue levels as of the end of the quarter ended June 30, 2012. As of March 31, 2015, 271,000 shares of common stock remain issuable pursuant to the plan of reorganization.

In connection with the Deerfield Facility Agreement, we entered into a Registration Rights Agreement (the “RRA”) with Deerfield and agreed to register, among other things, shares of our common stock issuable upon conversion and exercise of convertible notes and related common stock warrants. In accordance with the RRA, we are obligated to file and maintain an effective registration statement until (i) the date when all shares underlying the convertible notes and related warrants (and any other securities issued or issuable with respect to in exchange for such shares) have been sold or (ii) at any time following the six month anniversary of the date of issuance, all warrant shares issuable upon exercise of the warrants should be eligible for immediate resale pursuant to Rule 144 under the Securities Act.

In conjunction with its U.S. Food and Drug Administration (“FDA”) clearance, we agreed to conduct a post-market surveillance study to further analyze the safety profile of bovine thrombin as used in the Aurix (formerly AutoloGel^TM) System. This study was 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 March 31, 2015, approximately $368,000 had been incurred. Since the inception of this study, we have enrolled 120 patients, noting no adverse events. Based on the additional positive safety data, we have suspended further enrollment in this study pending further discussion with the FDA.

Our primary office and warehouse facilities are located in Gaithersburg, Maryland, and comprise approximately 12,000 square feet. The facilities fall under two leases with monthly rent, including our share of certain annual operating costs and taxes, at approximately $13,000 and $4,000 per month, respectively, with each lease expiring in September 2019. In addition, we lease a 2,076 square foot facility in Nashville, Tennessee, which is being utilized as a commercial operations. The lease is approximately $4,000 per month excluding our shares of annual operating expenses and expires April 30, 2018. We also lease a 16,300 square foot facility located in Durham, North Carolina. This facility falls under one lease with monthly rent, including our share of certain annual operating costs and taxes, at approximately $20,000 per month with the lease expiring December 31, 2018. As a result of our discontinuance of the ALD-401 clinical trial, the Company ceased use of the facility in Durham, North Carolina on July 31, 2014 and sublet the facility beginning August 1, 2014. The sublease rent is approximately $13,000 per month and expires December 31, 2018.

In July 2009, in satisfaction of a Maryland law pertaining to Wholesale Distributor Permits, we 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 us of our obligations under applicable Maryland law and is collateralized by a Certificate of Deposit maintained at a commercial bank.

The Company and the MVF agreed to execute a certain Stock Repurchase Agreement which requires us to repurchase the MVF’s investment, at MVF’s option, upon certain events outside of our control; provided, however, that in the event that, at the time of either such event our securities are listed on a national securities exchange, the foregoing repurchase will not be triggered.
