Commission File No.: 1-9026

This filing relates to a planned merger (the “Merger”) between Hewlett-Packard Company (“HP”) and Compaq Computer Corporation (“Compaq”) pursuant to the terms of an Agreement and Plan of Reorganization, dated as of September 4, 2001 (the “Merger Agreement”), by and among HP, Heloise Merger Corporation and Compaq. The Merger Agreement is on file with the Securities and Exchange Commission as an exhibit to the Current Report on Form 8-K, as amended, filed by Hewlett-Packard Company on September 4, 2001, and is incorporated by reference into this filing.

The following is an advertisement first published by HP on January 27, 2002.

By merging with Compaq, the new HP will become the market leader
in servers, storage, management software,
printing and imaging, and PCs, improving our ability to offer
the end-to-end solutions customers demand.

We will double our profitable and growing services business, enhance our
R&D efforts, and extend our customer reach in 160 countries.

We will achieve annual cost savings of $2.5 billion, adding $5 to $9 in
present value to each HP share; and increase earnings
per share by 13% during the first year following the merger.

By improving profitability in enterprise computing systems, in PCs and access devices,
and in IT services, we will have the financial strength to extend our
successful imaging and printing franchise into new multi-billion dollar categories
like digital imaging and digital publishing.

All of this, of course, requires that we execute well; and we will.
Indeed, those who suggest that the challenges ahead are beyond us
greatly underestimate the people of the new HP.

The closer you look, the more you will see that the merger of HP and Compaq
is the single best way to strengthen our businesses and improve our
market position, deliver more of what our customers need, enhance opportunities
for our employees, and increase the value of your investment.
