                                  OUR BUSINESS

        Cray Inc. designs, builds, sells and services high-performance computer
systems, sometimes referred to as "supercomputers." Our executive offices are
located at Merrill Place, Suite 600, 411 First Avenue South, Seattle, WA
98104-2860, and our telephone number is (206) 701-2000.

                               SELLING SHAREHOLDER

        On June 21, 1999, we issued a warrant to Terren S. Peizer in exchange
for $200,000. The warrant presently is exercisable for 5,139,408 shares of our
common stock at an exercise price of $2.53 per share. As of March 21, 2001, the
warrant is exercisable for 4,496,982 of these shares; the remaining shares
become exercisable ratably per month over the next three months so that the
warrant is exercisable in full on June 21, 2001. If certain events occur prior
to June 21, 2001, such as a merger or consolidation in which we are not the
surviving entity or a sale of all or substantially all of our assets, or if we
terminate our relationship with Mr. Peizer, the vesting provisions accelerate.

        The issuance of the warrant to Mr. Peizer is described more fully in our
Current Report on Form 8-K for the event of June 21, 1999, as filed with the
Securities and Exchange Commission (the "SEC") on June 30, 1999.

        As of March 23, 2001, Mr. Peizer held no shares of our Common Stock. The
shares covered by this prospectus include only the shares of common stock
issuable to Mr. Peizer pursuant to the exercise of the warrant described above.
All of the shares covered by this prospectus are being sold for the account of
Mr. Peizer. As of March 23, 2001, we had 39,375,541 shares outstanding.

        Mr. Peizer served as our Chairman of the Board from June 25, 1999 to
December 21, 2000.

        In recognition of the fact that Mr. Peizer may wish to be legally
permitted to sell its shares when it deems appropriate, we have agreed with Mr.
Peizer to file with the SEC, under the Securities Act of 1933 (the "Securities
Act"), a registration statement on Form S-3, of which this prospectus forms a
part, with respect to the resale of the shares issuable upon exercise of the
warrant, and have agreed to prepare and file such amendments and supplements to
the registration statement as may be necessary to keep the registration
statement effective until such shares are no longer required to be registered
for sale by Mr. Peizer.

                              PLAN OF DISTRIBUTION


                                      -3-
   6
        Cray is registering the shares covered by this prospectus for Mr.
Peizer. Mr. Peizer or his pledgees, donees, transferees or other successors in
interest may sell the shares in the over-the-counter market or otherwise, at
market prices prevailing at the time of sale, at prices related to prevailing
market prices, or at negotiated prices. In addition, the shares may be sold by
one or more of the following methods:

        o       a block trade in which a broker or dealer so engaged will
                attempt to sell the shares as agent but may position and resell
                a portion of the block, as principal, in order to facilitate the
                transaction;

        o       purchases by a broker or dealer, as principal, in a market maker
                capacity or otherwise and resale by the broker or dealer for its
                account pursuant to their prospectus; or

        o       ordinary brokerage transactions and transactions in which a
                broker solicits purchases.

        Cray will pay the costs and fees of registering the shares, but Mr.
Peizer will pay any brokerage commissions, discounts or other expenses relating
to the sale of the shares. Cray and Mr. Peizer each have agreed to indemnify the
other against certain liabilities, including liabilities arising under the
Securities Act, that relate to statements or omissions in the registration
statement of which this prospectus forms a part.

        Regulation M under the Securities Exchange Act of 1934 provides that
during the period that any person is engaged in the distribution, as so defined
in Regulation M, of our common stock, such person generally may not purchase
shares of our common stock. Mr. Peizer is subject to applicable provisions of
the Securities Act and the Securities Exchange Act of 1934 and the rules and
regulations thereunder, including, without limitation, Regulation M, which
provisions may limit the timing of purchases and sales of shares of our common
stock by Mr. Peizer. The foregoing may affect the marketability of our common
stock.

        Mr. Peizer may negotiate and pay brokers or dealers commissions,
discounts or concessions for their services. In effecting sales, brokers or
dealers engaged by Mr. Peizer may allow other broker or dealers to participate.
However, Mr. Peizer and any brokers or dealers involved in the sale or resale of
the shares may qualify as "underwriters" within the meaning of the Section
2(a)(11) of the Securities Act. In addition, the brokers' or dealers'
commissions, discounts or concessions may qualify as underwriters' compensation
under the Securities Act. If Mr. Peizer qualifies as an "underwriter," it will
be subject to the prospectus delivery requirements of Section 5(b)(2) of the
Securities Act.

        In addition to selling its shares under this prospectus, Mr. Peizer may:

        o       agree to indemnify any broker or dealer or agent against certain
                liabilities related to the selling of the shares, including
                liabilities arising under the Securities Act;

        o       transfer its shares in other ways not involving market makers or
                established trading markets, including directly by gift,
                distribution, or other transfer; or


                                      -4-
   7
        o       sell its shares under Rule 144 of the Securities Act rather than
                under this prospectus, if the transaction meets the requirements
                of Rule 144.

        Upon notification by Mr. Peizer that any material arrangement has been
entered into with a broker or dealer for the sale of the shares through a block
trade, special offering, exchange distribution or secondary distribution or a
purchase by a broker or dealer, we will file a supplement to this prospectus, if
required, pursuant to Rule 424(b) under the Securities Act, disclosing the
material terms of the transaction.

                                  LEGAL MATTERS

        For purposes of this offering, Kenneth W. Johnson, the Company's General
Counsel, is giving an opinion on the validity of the common shares. As of the
date of this prospectus, Mr. Johnson held 39,713 shares of the Company's common
stock and options exercisable for 270,000 shares of the Company's common stock.

                                     EXPERTS


        The financial statements incorporated in this prospectus by reference
from the Company's annual report on Form 10-K for the year ended December 31,
2000, have been audited by Deloitte & Touche LLP, independent auditors, as
stated in their report, which is incorporated herein by reference, and have
been so incorporated in reliance upon the report of such firm given upon their
authority as experts in accounting and auditing.


                   LIMITATION OF LIABILITY AND INDEMNIFICATION

        Our Restated Articles of Incorporation provide that, to the fullest
extent permitted by the Washington Business Corporation Act, our directors will
not be liable for monetary damages to Cray or its shareholders, excluding,
however, liability for acts or omissions involving intentional misconduct or
knowing violations of law, illegal distributions or transactions from which the
director receives benefits to which the director is not legally entitled. Our
Restated Bylaws provide that Cray will indemnify its directors and, by action of
the Board of Directors, may indemnify its officers, employees and other agents
to the fullest extent permitted by applicable law, except for any legal
proceeding that is initiated by such directors, officers, employees or agents
without authorization of the Board of Directors.


                                      -5-
   8
        Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of Cray
pursuant to the foregoing provisions, or otherwise, we have been advised that,
in the opinion of the SEC, such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable.

                      INFORMATION INCORPORATED BY REFERENCE

        The SEC allows us to "incorporate by reference" our publicly-filed

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 14.    Other Expenses of Issuance and Distribution.

        The Company will pay all expenses in connection with the issuance and
distribution of the securities being registered. The following is an itemized
statement of these expenses (all amounts are estimated except for the SEC fees):

        SEC Registration fee.............................     $3,251

        Legal fees.......................................     $5,000

        Accountant's Fees................................     $2,500

        Miscellaneous....................................     $2,249

        Total............................................     $13,000

Item 15.    Indemnification of Officers and Directors.

        Article XII of the Company's Restated 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 "Act"). Sections
23B.08.500 through 23B.08.600 of the Act authorize a court to award, or a
corporation's board of directors to grant, indemnification to directors and
officers on terms sufficiently broad to permit indemnification under certain
circumstances for liabilities arising under the Securities Act.

        Section 23B.08.320 of the Act 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.

                        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;

                        (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 material information with respect
                                to the plan of distribution not previously
                                disclosed in the registration statement or any
                                material change to such information in the
                                registration statement;

                        provided, however, that paragraphs (a)(1)(i) and
                        (a)(1)(ii) do not apply if the information required to
                        be included in a post-effective amendment by those
                        paragraphs is contained in periodic reports filed with
                        or furnished to the Commission by the registrant
                        pursuant to Section 13 or Section 15(d) of the Exchange
                        Act that are incorporated by reference in the
                        registration statement;

                (2)     That, for the purpose of determining any liability under
                        the Securities Act, 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; and

                (3)     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.


   12
        (b)     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.

        (c)     Insofar as indemnification for liabilities arising under the
                Securities Act 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 Commission such indemnification is against
                public policy as expressed in the Securities 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 Securities Act and will be governed by the final
                adjudication of such issue.
