StorageTek has agreed to file a proxy statement in connection with the proposed acquisition. The proxy statement will be mailed to the stockholders of StorageTek. StorageTek's stockholders are urged to read the proxy statement and other relevant materials when they become available because they will contain important information about the acquisition and StorageTek. Investors and security holders may obtain free copies of these documents (when they are available) and other documents filed with the Securities and Exchange Commission (the "SEC") at the SEC's web site at www.sec.gov. In addition, investors and security holders may obtain free copies of the documents filed with the SEC by StorageTek by going to StorageTek's Investor Relations page on its corporate website at www.storagetek.com.

In addition, StorageTek and its officers and directors may be deemed to be participants in the solicitation of proxies from StorageTek's stockholders with respect to the acquisition. A description of any interests that StorageTek's officers and directors have in the acquisition will be available in the proxy statement. In addition, Sun may be deemed to have participated in the solicitation of proxies from StorageTek's stockholders in favor of the approval of the acquisition. Information concerning Sun's directors and executive officers is set forth in Sun's proxy statement for its 2004 annual meeting of stockholders, which was filed with the SEC on September 22, 2004, and annual report on Form 10-K filed with the SEC on September 13, 2004.
