(the "Company"), at the request of the Company: Re: Stock Option Exchange Program On Wednesday, February 26, 2003, the Company's shareholders approved the plan to allow the Company to offer a stock option exchange program to its employees. Within the next two weeks, offering documents will be emailed to each employee outlining the stock option exchange program and providing the forms to be completed for those employees who want to participate. At this time, we suggest that employees may wish to access their stock option summaries by reviewing their E*Trade OptionsLink accounts at https://optionslink.etrade.com/e/t/applogic/OLHome so they have this available when they receive the material on the stock option exchange program. * * * This message does not constitute an offer to holders of options to tender their outstanding options for new options. While the electronic e-mail message does not constitute a commencement of the offer, the Company intends that the Exchange Program will commence within approximately two weeks. However, the Board of Directors may determine not to proceed with the Exchange Program even though the stockholders have approved the proposal permitting the Exchange Program. AT THE TIME THE EXCHANGE PROGRAM IS COMMENCED, THE COMPANY WILL PROVIDE OPTION HOLDERS WHO ARE ELIGIBLE TO PARTICIPATE IN THE EXCHANGE PROGRAM WITH WRITTEN MATERIALS EXPLAINING THE PRECISE TERMS AND TIMING OF THE EXCHANGE PROGRAM. PERSONS WHO ARE ELIGIBLE TO PARTICIPATE IN THE EXCHANGE PROGRAM SHOULD READ THESE WRITTEN MATERIALS CAREFULLY WHEN THEY BECOME AVAILABLE BECAUSE THEY CONTAIN IMPORTANT INFORMATION ABOUT THE EXCHANGE PROGRAM. THE COMPANY WILL ALSO FILE THESE WRITTEN MATERIALS WITH THE SECURITIES AND EXCHANGE COMMISSION AS PART OF A TENDER OFFER STATEMENT UPON THE COMMENCEMENT OF THE EXCHANGE PROGRAM. THE COMPANY'S STOCKHOLDERS AND OPTION HOLDERS WILL BE ABLE TO OBTAIN THESE WRITTEN MATERIALS AND OTHER DOCUMENTS FILED BY THE COMPANY WITH THE SECURITIES AND EXCHANGE COMMISSION FREE OF CHARGE FROM THE SECURITIES AND EXCHANGE COMMISSION'S WEBSITE AT WWW.SEC.GOV.
