At the Annual Meeting of Shareholders of The Sherwin-Williams Company (“Sherwin-Williams”) held on April 18, 2012, Sherwin-Williams’ shareholders approved the amendment and restatement of The Sherwin-Williams Company 2007 Executive Performance Bonus Plan (“2007 Performance Plan”).

The 2007 Performance Plan is designed as a vehicle for payments of annual cash compensation that is intended to be fully deductible for federal income tax purposes by Sherwin-Williams under Section 162(m) of the Internal Revenue Code. The 2007 Performance Plan was amended to (a) add a recoupment or “clawback” provision clarifying that awards under the 2007 Performance Plan may be forfeited and repaid to Sherwin-Williams in accordance with Sherwin-Williams’ Executive Adjustment and Recapture Policy; (b) increase the maximum amount payable to any participant to $5 million per year; and (c) make certain other conforming and non-substantive changes.

The 2007 Performance Plan, as amended and restated, is filed as Exhibit 10(a) to this Report and is incorporated herein by reference.

At the Annual Meeting, Sherwin-Williams’ shareholders also elected Richard J. Kramer as a new director to serve on Sherwin-Williams’ Board of Directors. Mr. Kramer is Chairman of the Board, Chief Executive Officer and President of The Goodyear Tire & Rubber Company. In connection with Mr. Kramer’s election to the Board, Sherwin-Williams entered into an Indemnity Agreement with him in the same form that Sherwin-Williams has entered into with its other directors and officers. The Form of the Indemnity Agreement was filed as Exhibit 10(a) to Sherwin-Williams’ Annual Report on Form 10-K for the fiscal year ended December 31, 1997 and is incorporated herein by reference. The Indemnity Agreement supplements the indemnification coverage afforded by Sherwin-Williams’ Regulations and Ohio law.
