ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On September 16, 2008, Interleukin Genetics, Inc. (the “Company”) entered into a research and license agreement with Geisinger Health System (“Geisinger”), a Pennsylvania non-profit corporation. Under their collaboration pursuant to this agreement, the parties will explore the role of genetics in obesity. The goal of the collaboration is to develop a series of genetic tests that will help physicians better understand an individual’s inherited resistance to weight loss and, more specifically, gauge a patient’s likelihood of success with diet and other weight loss techniques. Geisinger and the Company will engage in a case-control retrospective study involving the analysis of DNA to better understand genetic links to obesity. The study will focus exclusively on variations of perilipin, interleukin 1 and a select number of other genes.

The Company will pay Geisinger over the course of the program up to an aggregate of $412,000 under the agreement, as well as specific payments for various tissue samples, to be used in the studies.

A copy of the Company’s press release announcing the Company’s entry into the research and license agreement is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
