WPS Resources Corporation CEO Weyers Adopts 10b5-1 Plan

GREEN BAY, Wis., Nov. 13 /PRNewswire-FirstCall/ — Larry L. Weyers, the chairman, president, and chief executive officer of WPS Resources Corporation (NYSE:WPS) , established a 10b5-1 plan to sell over a period of one year, commencing on November 22, 2006, a portion of his common stock holdings in WPS Resources. A 10b5-1 plan allows directors and officers of a company to buy or sell company stock on a regular, systematic basis, without risking liability under federal insider trading laws. Transactions executed by directors and officers under this plan are not subject to normal blackout periods that would otherwise be imposed by WPS Resources.

Mr. Weyers established the plan as part of a strategy to diversify his investments over the next year. The shares being sold through the plan consist of shares directly held by Mr. Weyers and shares he has the right to acquire through the exercise of certain of his stock options.

Following the proposed sale, Mr. Weyers will continue to own a substantial number of shares of common stock of WPS Resources. Common stock holdings of officers and directors are reported each year in the proxy statement. Mr. Weyers is also required to meet Board of Directors approved stock ownership guidelines. It is expected that Mr. Weyers will continue to meet the stock ownership requirements after completion of the sales under his 10b5-1 plan.
