Note 12 - Licensing and Supply Agreement

On April 27, 2007 (the “Effective Date”) Enzo Life Sciences, Inc. (“Life Sciences”) and Abbott Molecular Inc. (“Abbott”) entered into a 5 year agreement, covering the supply of certain of Enzo Life Sciences products to Abbott for use in their product line. The parties also entered into a limited non-exclusive royalty bearing cross-licensing agreement (“Licensing Agreement”) for various patents. The Licensing Agreement required each party to pay royalties, as defined through the lives of the related non-expired patents. During the years ended July 31, 2011 and 2010, the Company recorded approximately $400 and $3,000, respectively, in royalties and license fee income under the Licensing Agreement. In January 2011, Abbott notified the Company that they have made a final royalty payment because they are unaware of any non-expired patents.
