        This Amendment No. 4 (this "Amendment") amends the Tender Offer Statement on Schedule TO (the "Schedule TO") filed by Hewlett-Packard Company, a Delaware corporation ("Hewlett-Packard" or the "Company"), with the Securities and Exchange Commission on November 17, 2006 and amended on December 4, 2006, December 8, 2006 and December 15, 2006, relating to the offer by the Company (the "Offer") to amend certain options (the "Eligible Options") that have been granted under the Mercury Interactive Corporation Amended and Restated 1999 Stock Option Plan, the Mercury Interactive Corporation Amended and Restated 2000 Supplemental Stock Option Plan, and the Mercury Interactive Corporation 2001 Inland Revenue Approved Sub-Plan for United Kingdom Employees: (i) that were assumed by Hewlett-Packard in connection with the acquisition of Mercury Interactive Corporation, which was completed on November 6, 2006, (ii) that had original exercise prices per share that were less than the fair market value per share of the common stock underlying the option on the option's grant date, (iii) that were unvested, either in whole or in part, as of December 31, 2004, (iv) that are outstanding as of the last date on which the Offer remains open for acceptance, and (v) that are held by individuals who are subject to taxation in the United States and who remain employees or other service providers of the Company or its subsidiaries through the expiration of the Offer.

        The Offer to Amend has been amended to change the eligibility requirements of the Offer. The change adds the requirement that an option holder remain an employee or other service provider of the Company or one of its subsidiaries through the expiration of the Offer in order to be eligible to participate. As a result of this change, the full requirements for an individual to be an "eligible option holder" and therefore be eligible to participate in the Offer are: all individuals who (1) are subject to United States taxation, (2) hold Eligible Options and (3) remain employees or other service providers of the Company, including one of its subsidiaries, through the expiration date.

        The Offer to Amend, Election form, Withdrawal form, form of acknowledgment of receipt of documents relating to the Offer and form of reminder e-mails and form of follow-up email to employees holding discounted stock options issued by Mercury Interactive Corporation who have not completed an agreement to amend, filed with the Schedule TO as exhibits (a)(1)(A), (a)(1)(C), (a)(1)(D), (a)(1)(G), (a)(1)(H) and (a)(1)(L), have been amended to reflect the extension of the Offer expiration date to 9:00 p.m. Pacific time on December 21, 2006. As a result, all references to the expiration date, amendment date and any other references to December 15, 2006 have been modified to refer to December 21, 2006.

        The Eligible Options may be amended pursuant to the terms and subject to the conditions set forth in: (i) the Offer to Amend the Exercise Price of Certain Options, dated November 17, 2006, as amended December 4, 2006, as further amended December 8, 2006 and December 15 (the "Offer to Amend"), (ii) the related e-mail to all eligible option holders from Tom Hogan, dated November 17, 2006, (iii) the Election Form, as amended, and (iv) the Withdrawal Form, as amended (collectively, the "Offer Documents"). The Offer Documents were filed with the Schedule TO as exhibits (a)(1)(A), (a)(1)(B), (a)(1)(C) and (a)(1)(D), respectively.

        The information in the Offer Documents, including all schedules and annexes thereto, is hereby expressly incorporated into this Amendment by reference to all of the applicable items in Schedule TO, except that such information is hereby amended and supplemented to the extent specifically provided herein.

Item 12. Exhibits.

        Item 12 of the Schedule TO is amended to add the following exhibit:

  (a)(1)(M)   Form of follow-up email to employees holding discounted stock options issued by Mercury Interactive Corporation describing certain amendments to the Offer
