Item 8.01                                             Other Events.

On November 15, 2011, Mark R. Bachmann, Executive Vice President and Chief Financial Officer of Zep Inc. (the “Company”), entered into a Rule 10b5-1 sales plan effective as of November 30, 2011 and terminating on December 17, 2013.  Under the sales plan, so long as the Company’s common stock meets certain threshold prices, Mr. Bachmann could effect a cashless exercise of up to 22,424 employee stock options.

The aforementioned Rule 10b5-1 sales plan is intended to satisfy the Company’s insider trading policy and the requirements of Rule 10b5-1 promulgated under the Securities Exchange Act of 1934, as amended.  Rule 10b5-1 permits individuals who are not in possession of material, non-public information at the time the plan is adopted to establish pre-arranged plans to buy or sell specified amounts of company stock.  Using these plans, among other objectives, individuals may gradually diversify their investment portfolios over an extended period of time.

Transactions for Mr. Bachmann under his respective Rule 10b5-1 sales plan will be disclosed publicly through Form 4 filings with the Securities and Exchange Commission.  Except as may be required by law, the Company does not undertake any obligation to report any modifications or terminations of any such plans, nor report any Rule 10b5-1 sales plans that may be adopted by other officers or employees of the Company.
