Item 4.    Description of Securities.

           Not applicable.

Item 5.    Interests of Named Experts and Counsel.

           For purposes of this offering, Kenneth W. Johnson, Cray's general
counsel, is giving an opinion on the validity of the common shares. As of the
date of this prospectus, Mr. Johnson held 40,538 shares of Cray's common stock
and options exercisable for 270,000 shares of Cray's common stock.

Item 6.    Indemnification of Director and Officers.

           Article XII of the Company's Articles of Incorporation and Section 11
of the Company's Restated Bylaws require indemnification of directors, officers,
employees, and agents of the Company to the fullest extent permitted by the
Washington Business Corporation Act (the "WBCA"). Sections 23B.08.500 through
23B.08.600 of the WBCA authorize a court to award, or a corporation's board of
directors to grant,


                                       2
   4
indemnification to directors and officers on terms sufficiently broad to permit
indemnification under certain circumstances for liabilities arising under the
Act.

           Section 23B.08.320 of the WBCA authorizes a corporation to limit a
director's liability to the corporation or its shareholders for monetary damages
for acts or omissions as a director, except in certain circumstances involving
intentional misconduct, self-dealing or illegal corporate loans or
distributions, or any transaction from which the director personally receives a
benefit in money, property or services to which the director is not legally
entitled. Article XI of the Company's Restated Articles of Incorporation
contains provisions implementing, to the fullest extent permitted by Washington
law, such limitations on a director's liability to the Company and its
shareholders.

Item 7.    Exemption from Registration Claimed.

           Not applicable.

Item 8.    Exhibits.

Item 9. Undertakings.

        1.      The undersigned registrant hereby undertakes:

                (a)     To file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement

                        (i)     To include any prospectus required by Section
10(a)(3) of the Securities Act of 1933, as amended;

                        (ii)    To reflect in the prospectus any facts or events
arising after the effective date of this Registration Statement (or the most
recent post-effective amendment thereof) that, individually or in the aggregate,
represent a fundamental change in the information set forth in this Registration
Statement; and

                        (iii)   To include any additional material information
with respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to information contained herein;

                        provided, however, that paragraphs (1)(a)(i) and
(1)(a)(ii) do not apply if the information required to be included in a
post-effective amendment by those paragraphs is incorporated by reference from
periodic reports filed by the registrant pursuant to Section 13 or Section 15(d)
of the Securities Exchange Act of 1934, as amended.

                (b)     That, for the purpose of determining any liability under
the Securities Act of 1933, as amended, each post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

                (c)     To remove from registration by means of a post-effective
amendment any of the securities being registered that remain unsold at the
termination of the offering.

        2.      The undersigned registrant hereby undertakes that, for purposes
of determining any liability under the Securities Act of 1933, each filing of
the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

        3.      Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

amended, the registrant certifies that it has reasonable grounds to believe that
it meets all of the requirements for filing on Form S-8 and has duly caused this
Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Seattle, State of Washington, on September 26,
2001.
