The following is an advertisement first published by HP on December 20, 2001. WHY IT MAKES SENSE. Because the combined customers of hp and Compaq will represent a vast and newly powerful community of technology users. Because on their behalf we will lead the technology transitions ahead. Because in one strategic move, we will become market leaders in servers, in storage and in management software--the essentials of business infrastructure, where leadership really counts. Because we will greatly strengthen our depth and breadth of technology solutions at a time when customers demand integrated, end-to-end solutions. Because we will double the number of consulting, outsourcing and support professionals dedicated to helping customers do business around the globe. Because more inventors and engineers will be focused on solving the toughest technology challenges of our times--together. Because combined we will lead the march toward open standards more effectively than either company could on its own. Because we will accelerate the changes required to improve our PC business, so we can offer customers a more competitive alternative. Because the best way to protect and grow our leadership in printing and imaging is to strengthen our enterprise computing, IT services and PC businesses. Because we intend to do all that and still decrease expenses $2.5 billion by 2004. Because for our employees, customers and shareowners, we will be a stronger, more vibrant hp, better conformed to lead and grow under market conditions that will demand unprecedented integration, breadth and flexibility. Because in our industry to stand still is to fall behind. Because this is the exact opposite of that.
