The Company accrued for the severance to be paid to Mr. Van Ness, as Mr. Van Ness has no significant continuing service obligation to the Company. Under the Asset Purchase Agreement (the “Asset Purchase Agreement”), dated July 25, 2012, between the Company and Progenics Pharmaceuticals, Inc.

On October 16, 2012, the Company paid to Progenics $3,500,000 in cash to close the transaction. The Company is also required to pay Progenics the following milestone payments and royalties: (i) $1,500,000 at the time of the first dosing in a U.S. Phase 3 trial or non-U.S. equivalent; (ii) $5,000,000 at the time of the first U.S. new drug application approval by the FDA or other non-U.S. approval for the sale of PRO 140; and (iii) royalty payments of up to 5% on net sales during the period beginning on the date of the first commercial sale of PRO 140 until the later of (a) the expiration of the last to expire patent included in the acquired assets, and (b) 10 years, in each case determined on a country-by-country basis. Payments to Progenics are in addition to payments due under a Development and License Agreement, dated April 30, 1999 (the “PDL License”), between Protein Design Labs (now AbbVie Inc.) and Progenics, which was assigned to the Company in the PRO 140 transaction, pursuant to which the Company must pay additional milestone payments and royalties as follows: (i) $1,000,000 upon initiation of a Phase 3 clinical trial; (ii) $500,000 upon filing a Biologic License Application with the FDA or non-U.S. equivalent regulatory body; (iii) $500,000 upon FDA approval or approval by another non-U.S. equivalent regulatory body; and (iv) royalties of up to 7.5% of net sales for the longer of 10 years and the date of expiration of the last to expire licensed patent. Additionally, the PDL License provides for an annual maintenance fee of $150,000 until royalties paid exceed that amount. In addition, from time to time, the Company is involved in claims and suits that arise in the ordinary course of business. Management currently believes that the resolution of any such claims against the Company, if any, will not have a material adverse effect on the Company’s business, financial condition or results of operations.
