(e)           On August 7, 2012, at the 2012 Annual Meeting of Shareholders (the “Annual Meeting”) of Interleukin Genetics, Inc. (the “Company”), the shareholders approved the Company’s 2012 Employee Stock Purchase Plan (the “Purchase Plan”), as described under Proposal 3 of Item 5.07 below. The Purchase Plan provides eligible employees with the opportunity to purchase up to 750,000 shares of the Company’s common stock, at a discount, on a tax-favored basis through payroll deductions in compliance with Section 423 of the Internal Revenue Code of 1986, as amended. The Purchase Plan replaces the Company’s outstanding Employee Stock Purchase Plan which was terminated as almost all shares thereunder had been issued as of March 31, 2012.  A description of the terms and conditions of the Purchase Plan is set forth in the Company’s definitive Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission on June 22, 2012 under the heading “Proposal 3: Approval of the 2012 Employee Stock Purchase Plan,” and is incorporated herein by reference. Such description is qualified in its entirety by reference to the actual terms of the Purchase Plan, a copy of which is filed as Exhibit 10.1 to this Form 8-K.

On August 9, 2012, the Company filed a certificate of amendment with the Delaware Secretary of State to increase the number of the Company’s authorized shares of common stock from 100,000,000 shares to 150,000,000 shares. The certificate of amendment became effective upon filing. A copy of the certificate of amendment is filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated by reference herein.

On August 6, 2012, the Company issued a press release announcing the preliminary, top line results that the Company has received from the Periodontal Disease Prevention Study (PDPS) being conducted by the University of Michigan School of Dentistry. The preliminary results indicate that in Low Risk patients, there was no significant difference between two dental preventive visits per year and one preventive visit per year in reducing the percentage of patients who had tooth extractions over the 16 year monitoring period; 13.8% versus 16.4% (p=0.092 ns). In addition, the preliminary results indicate that in High Risk patients, two preventive visits per year significantly reduced the percentage of patients who had extractions over a 16 year monitoring period compared to one preventive visit per year; 16.9% vs. 22.1% (p=0.002). There was also a positive relationship between number of risk factors and the percentage of patients with extractions (p<0.001). The Low Risk population (approximately 47% of the study) was defined as non-smokers, genetically negative per the Company’s PST test and no history of diabetes. High Risk patients were defined as having one or more risk factors, i.e. PST positive, diabetes or smoking.
