For purposes of the offer, Hewlett-Packard will be deemed to have accepted options with respect to which proper elections have been made and not properly withdrawn as of the date when Hewlett-Packard gives oral or written notice to the option holders generally of its acceptance of such options, which notice may be made by press release, e-mail or other method of communication. Hewlett-Packard's formal acceptance is expected to take place shortly after the end of the offer period.
