The Company had license revenues of $11,290 for the quarter ended March 31, 2011 compared to $0 for the comparative prior year quarter. This increase resulted from the Company ’ s license agreement with Rockbrook signed on August 18, 2010 and the associated recognition of license fees paid by Rockbrook to the Company for the distribution of its products. We are currently negotiating new license agreement terms with Rockbrook to remove the exclusivity clause and permit the Company to seek other licensees to market its products and add additional license revenues. The new agreement is expected to be signed on or before May 20, 2011.
