On June 9, 2011, Joseph E. Dondanville, Chief Financial Officer of RLI Corp. (“RLI”), entered into a Rule 10b5-1 Sales Plan (“Plan”) for the period between August 9, 2011 and August 9, 2012.  Under the Plan, so long as RLI’s common stock meets certain threshold prices, Mr. Dondanville could sell up to 25,000 shares of common stock.  Mr. Dondanville entered into the Plan in order to allow him to sell a portion of his RLI stock as part of his long-term strategy for individual asset diversification and liquidity.

The Plan is intended to comply with Rule 10b5-1 of the Securities and Exchange Act of 1934 and RLI’s insider trading policy.  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.

All stock sales under the Plan will be disclosed in accordance with applicable rules of the Securities and Exchange Commission.  Except as may be required by law, RLI 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 RLI.
