On February 23, 2006, Interleukin Genetics, Inc. entered into two new Purchase Agreements with Access Business Group International LLC, a subsidiary of Alticor Inc. On the same date, Interleukin Genetics also amended its Note Purchase Agreement and Stock Purchase Agreement with Pyxis Innovations Inc., another affiliate of Alticor, to provide Interleukin with access up to an additional $3.5 million of borrowing for general working capital purposes. The two new Purchase Agreements cover two genetic tests that Interleukin Genetics developed on behalf of Alticor. These are: 1) the heart health genetic test, which analyzes DNA variations in the Interleukin-1A and 1B genes to identify whether an individual may have a predisposition for chronically elevated measures of inflammation and an increased risk for heart disease; and 2) the general nutrition genetic test, which analyzes DNA variations in two genes that affect Vitamin B metabolism and four genes that are involved in responding to oxidative stress. These tests will be marketed exclusively through Quixtar, a subsidiary of Alticor, under Quixtar's GensonaTM brand. The Purchase Agreement for Interleukin's heart health genetic test has a term of two years and becomes effective March 23, 2006, upon the expiration of the current Distribution Agreement between the parties. The Purchase Agreement provides that $0.6 million of the $2.0 million prepayment under the Distribution Agreement will be applied to purchases made under the new agreement. The term of the Purchase Agreement for Interleukin's general nutrition genetic test is through January 2008. The Note Purchase Agreement was amended to provide Interleukin with access to an additional $2.0 million of working capital borrowing at any time prior to April 1, 2007. Any amounts borrowed will bear interest at prime plus 1%, require quarterly interest payments and be due five years from the date of the borrowing. The Stock Purchase Agreement was amended to remove certain restrictions on an existing $1.5 million line of credit so that it can be used for general working capital purposes. SIGNATURE Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
