The letter was especially disturbing in its numerous factual inaccuracies, its racial attack on those who have come to America from other countries, and its personal assault on my colleague, Pete Nelson. I speak on behalf of your Board of Directors when I express our complete confidence in our President and Chief Executive Officer, Pete Nelson. His breadth of experience, vision, and dedication to increasing shareholder value and providing excellent customer service make him a critical asset to our company and its long-term success. Moreover, I can assure you that the California Water Service Group has the leadership, financial strength, and strategy to continue its long history of exemplary performance. Cal Water has always been known for its candor and its commitment to doing the right thing for stockholders, customers, and employees. I know you share my pride in all that the company has accomplished, and we look forward to reviewing those accomplishments at our annual meeting in San Jose on April 24, 2002. Thanking you for your confidence in the California Water Service Group and hoping to see you in April, I am Very truly yours, /s/ Robert W. Foy Robert W. Foy Chairman of the Board
