ITEM 8.01 Other Events.

Michael V. Schrock, President and Chief Operating Officer of Pentair, Inc. (the “Company”), has entered into a prearranged stock trading plan to exercise options and affect a same day sale of the underlying shares. The stock trading plan was adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934. The general purpose of the plan is to allow for the exercise of options that will expire on January 2, 2011.

Rule 10b5-1 plans permit directors and officers who are not in possession of material, non-public information to establish prearranged plans to buy or sell company stock. Once the plan is in place, the executive may not retain or exercise any discretion over trading under the plan, although the executive may later amend or terminate the plan. The broker administering the plan is authorized to trade company shares in volumes and at times determined independently by the broker, subject to limitations set forth in the plan.

The plan will terminate by January 1, 2011. The transactions under this plan will be disclosed publicly through Form 4 filings with the Securities Exchange Commission. The Form 4 filings will also be posted on Pentair’s investor relations Web site.

The plan was adopted during an authorized trading period at a time when Mr. Schrock was not in possession of material, non-public information.
