SCRIPT

        "I wanted to take this opportunity to provide you with information regarding a stock option exchange program that we intend to offer to you starting on August 1. As a result of SEC rules governing this program, I will be reading this portion of the presentation from a script that was filed with the SEC earlier today, and will be unable to take any questions or answer any emails regarding the program until we send you the official offer. However, please be assured that we will do our utmost to help you understand this offer once it has commenced, and that this offer will be open for approximately four weeks so that you will have ample time to consider whether you want to participate in the program.

        "We intend to commence this program on August 1, and you will be receiving complete details regarding the offer via email on that date. We thought that this was an appropriate forum in which to inform you about our intention to implement this program and to share with you some of the highlights of the program.

        "Many of you have stock options with exercise prices that are significantly higher than the current market price of our stock. Over the past year, we have distributed three groups of supplemental stock option grants in part to address this issue. Unfortunately the market has not recovered sufficiently for the supplemental grants to have the incentive value we desired. This stock option exchange program is meant to reaffirm our commitment to shared success for employees and shareholders.

        "The basic elements of the stock option exchange program will be as follows.

        "At your request, we will exchange outstanding options with an exercise price of $15.00 or greater with new options granted and priced six months and one day after the surrender date, which we expect to occur on or about August 29, 2002. For every three shares of common stock covered by an option that you surrender for exchange, you will receive an option to purchase one share of common stock at an exercise price equal to the fair market value of our common stock on the date that the new option

2



is granted. The six month and a day delay in granting the new options enables us to avoid potentially large charges against our future earnings.

        "The new options granted pursuant to this program will have a new vesting schedule that is different from the standard vesting schedule for ATG options. Specifically, 25% of each new option will vest immediately on the date the new options are granted, which is anticipated to occur on or about March 3, 2003. The remaining shares exercisable pursuant to the option will vest in three equal installments over the following eighteen months, resulting in an additional 25% of the shares subject to the new option vesting every six months after the grant date.

        "This offer will be open for approximately four weeks. Within this timeframe it will be important for you to seek whatever financial advice you need in order to make the decision that is right for you. Once again, we intend to make this offer on August 1, and we will be happy to answer your questions regarding specific components of the program at that time."
