Item 8.01. Other Events.

On May 30, 2008, Joel F. Gemunder, the President and Chief Executive Officer of Omnicare, Inc. (the “Company”), entered into a written stock sales plan (the “Plan”) in accordance with the guidelines specified under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the Company’s policies regarding securities transactions.

Under the Plan, a broker not affiliated with the Company will sell shares of Omnicare common stock either owned by Mr. Gemunder or issued upon the exercise of certain of his Omnicare stock options. Any sales are subject to share amounts, minimum prices and other conditions set forth in the Plan and will be made during the period from July 1, 2008 to May 28, 2010.

Rule 10b5-1 allows corporate insiders who are not in possession of material non-public information to establish pre-arranged plans to buy or sell stock. These plans are generally designed to minimize the market effect of insider purchases or sales by spreading these purchases or sales over a more extended period. Additionally, through the use of these plans, insiders can gradually diversify their investment portfolios and can avoid real or perceived conflicts of interest in connection with the trading of securities.

Any sales made under the Plan will be publicly disclosed as required by applicable securities laws.
