the year on a very strong note with excellent momentum continuing into the new
year. There was over $500 million in shareholder value created by the Company
during 2003. Our goal in 2004 is to maintain this value and build upon it. The
financial crisis of the Company has been fixed and we have significantly
improved our operations. As we transition from a turnaround story, we are
focused on earnings and cash flow. Given accelerating industry demand, we look
forward to 2004 and beyond with great expectations. These expectations are
consistent with our recent accomplishments."
