THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "ACT"), OR ANY STATE SECURITIES LAWS. THE SALE TO THE HOLDER OF
THIS SECURITY AND OF THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE OF THIS
SECURITY ARE NOT COVERED BY A REGISTRATION STATEMENT UNDER THE ACT OR
REGISTRATION UNDER STATE SECURITIES LAWS. THIS SECURITY HAS BEEN ACQUIRED, AND
SUCH SHARES OF COMMON STOCK MUST BE ACQUIRED, FOR INVESTMENT ONLY AND MAY NOT BE
SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF REGISTRATION OF THE RESALE
THEREOF OR AN OPINION OF COUNSEL REASONABLY ACCEPTABLE IN FORM, SCOPE AND
SUBSTANCE TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

Warrant No. F-2                           Warrant to Purchase 150,000
                                          Shares of Common Stock


                                     WARRANT

THIS CERTIFIES THAT, for value received, The Gray Family Foundation 1997 (the
"Holder"), is entitled to purchase from CRAY INC., a Washington corporation (the
"Company"), at the price and during the period as hereinafter specified, up to
One Hundred Fifty Thousand (150,000) shares of common stock, $.01 par value
("Common Stock"), at a purchase price of $3.50 per share, subject to adjustment
as described in Section 8 hereof (the "Exercise Price"), at any time during the
period commencing on the date hereof, and extending through May 17, 2004 (the
"Expiration Date"). After the Expiration Date, the Holder shall have no right to
purchase any shares of Common Stock hereunder.

      1. This Warrant is issued pursuant to and is subject to the terms of a
Consulting Agreement of even date between the Company and Holder (the
"Consulting Agreement").

      2. (a) The rights represented by this Warrant may be exercised at any time
within the periods above specified, in whole or in part, by (i) the surrender of
this Warrant (with the purchase form at the end hereof properly executed) at the
principal executive office of the Company (or such other office or agency of the
Company as it may designate by notice in writing to the Holder at the address of
the Holder appearing on the books of the Company); (ii) payment to the Company
of the exercise price then in effect for the number of shares of Common Stock
specified in the above-mentioned purchase form together with applicable stock
transfer taxes, if any; and (iii) delivery to the Company of a duly executed
agreement signed by the person(s) designated in the purchase form to the effect
that such person(s) agree(s) to be bound by the provisions of Section 6 and
Subsections 7(b), 7(c) and 7(d) hereof. This Warrant shall be deemed to have
been exercised, in whole or in part to the extent specified, immediately prior
to the close of business on the date this Warrant is surrendered and payment is
made in accordance with the foregoing provisions of this Section 2, and the
person or persons in whose name or names the certificates for shares of Common
Stock shall be issuable upon such exercise shall become the holder or holders of
record of such Common Stock at that time and date. The certificates for the
Common Stock so purchased shall be delivered to the Holder within a reasonable
time, not exceeding five (5) business days, after the rights represented by this
Warrant shall have been so exercised.
<PAGE>
            (b) Notwithstanding anything to the contrary contained in Section
2(a), the Holder may elect to exercise this Warrant in whole or in part by
receiving shares of Common Stock equal to the value (as determined below) of
this Warrant, or any part hereof, upon surrender of this Warrant at the
principal executive office of the Company together with notice of such election
in which event the Company shall issue to the Holder a number of shares of
Common Stock computed using the following formula:

                        X = Y(A-B)
                            ------
                              A

            Where X = the number of Shares of Common Stock to be issued to the
                  Holder;

                  Y = the number of shares of Common Stock issuable upon the
                  exercise of this Warrant, or part thereof (the "Shares");

                  A = the current fair market value of one share of Common Stock
                  on the second trading day immediately preceding the day this
                  Warrant is surrendered pursuant to this Section 2(b); and

                  B = the Exercise Price of this Warrant.

      As used herein, current fair market value of Common Stock on any day shall
mean, with respect to each share of Common Stock, the closing price of the
Company's Common Stock sold on the principal national securities exchange on
which the Common Stock is at the time admitted to trading or listed, or, if the
Common Stock is not admitted for trading on a national securities exchange or if
any such exchange is not the principal trading market for the Common Stock, the
last sale price as reported by the Nasdaq Stock Market or the National
Association of Securities Dealers, Inc. ("NASD"), as the case may be, if the
Common Stock is quoted on the Nasdaq National Market or Nasdaq SmallCap Market
or is quoted on the NASD OTC Bulletin Board, in each case as officially reported
by such exchange, Nasdaq Stock Market or NASD, or, if there have been no sales
on such day, the average of the closing prices (if any exchange) or the last
sale prices (if Nasdaq or NASD OTC Bulletin Board), for the immediately
preceding three trading days, in each case of officially reported. If on the
date for which current fair market value is to be determined the Common Stock is
not listed on any securities exchange or on the Nasdaq Stock Market or NASD OTC
Bulletin Board, the current fair market value of Common Stock shall be the
highest price per share which the Company could then obtain from a willing buyer
(not a current employee or director) for shares of Common Stock sold by the
Company, from authorized but unissued shares, as determined in good faith by the
Board of Directors of the Company, unless prior to such date the Company has
become subject to a binding agreement for a merger, acquisition or other
consolidation pursuant to which the Company is not the surviving party, in which
case the current fair market value of the Common Stock shall be deemed to be the
value to be received by the holders of the Company's Common Stock for each share
thereof pursuant to such merger, acquisition or consolidation.

            (c) This Warrant may be exercised in whole or in part. If the event
of the exercise in part only, upon surrender of this Warrant for cancellation,
together with the duly executed purchase form and funds (or conversion
equivalent) sufficient to pay any Exercise Price, the Company shall cause to be
delivered to the Holder without charge a new Warrant of like tenor to this
Warrant in the name of the Holder evidencing the right of the Holder to purchase
the aggregate number of shares of Common Stock purchasable hereunder as to which
this Warrant has not been exercised or assigned.

            (d) Upon receipt by the Company of evidence satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant and of reasonably
satisfactory indemnification, the
<PAGE>
Company shall execute and deliver a new Warrant of like tenor and date. Any such
new Warrant executed and delivered as a result of such loss, theft, mutilation
or destruction shall constitute a substitute contractual obligation on the part
of the Company.

      3. This Warrant is transferable, and may be sold, assigned or
hypothecated, subject to compliance with applicable federal and state securities
laws. Any such assignment shall be effected by the Holder by (i) executing the
form of assignment at the end hereof and (ii) surrendering this Warrant for
cancellation at the office or agency of the Company referred to in Section 2
hereof, whereupon the Company shall issue, in the name or names specified by the
Holder (including the Holder), a new Warrant or Warrants of like tenor and
representing in the aggregate rights to purchase the same number of shares of
Common Stock as are purchasable hereunder at such time.

      4. The Company covenants and agrees that all shares of Common Stock which
may be purchased hereunder will, upon issuance and delivery against payment
therefor as provided herein, be duly and validly issued, fully paid and
non-assessable. The Company further covenants and agrees that, during the period
within which this Warrant may be exercised, the Company will at all times have
authorized and reserved a sufficient number of shares of its Common Stock for
issuance upon exercise of this Warrant.

      5. This Warrant shall not entitle the Holder to any voting rights or other
rights, including without limitation notice of meetings of other actions or
receipt of dividends, as a shareholder of the Company.

      6. (a) The Company shall advise the Holder, whether the Holder holds this
Warrant or has exercised this Warrant and holds shares of Common Stock related
thereto, by written notice at least two (2) weeks prior to the filing of any new
registration statement thereto under the Securities Act of 1933 (the "Act") for
a public offering of securities, covering any shares of Common Stock of the
Company, for its own account or for the account of others, except for any
registration statement filed on Form S-4 or S-8 (or other comparable form), and
will, during the period from the date hereof through the Expiration Date, upon
the request of the Holder, by giving written notice to the Company within seven
(7) days of its receipt of the Company's notice of its intent to file, include
in any such new registration statement such information as may be required to
permit a public offering of all or any of the Common Stock issuable upon the
exercise of this Warrants (the "Registrable Securities). The Company shall use
its best efforts to cause any registration statement filed pursuant to this
Section 6(a) that is declared effective to remain effective and shall maintain a
current prospectus relating thereto until all Registrable Securities have been
sold or are freely saleable without restriction under Rule 144 (or its
successor). The delivery by the Holder of any such notice shall not constitute a
demand made pursuant to Section 6(b). The Company shall supply prospectuses and
such other documents as the Holder may reasonably request in order to facilitate
the public sale or other disposition of the Registrable Securities, use its best
efforts to register and qualify any of the Registrable Securities for sale in
such states (i) as such Holder designates and (ii) with respect to which the
Company obtained a qualification in connection with its initial public offering;
and do any and all other acts and things which may be necessary or desirable to
enable such Holder to consummate the public sale or other disposition of the
Registrable Securities, all at no expense to the Holder (other than sales
commissions, underwriting discounts or commissions, or other expenses of such
sale), and furnish indemnification in the manner provided in Section 7 hereof.
The Holder shall furnish to the Company information and indemnification as set
forth in Section 7.

            (b) At any time after November 17, 2002, and prior to the Expiration
Date, a 50% Holder (as defined below) may request, on one occasion, that the
Company register under the Act any and all of the Registrable Securities held by
such 50% Holder. Upon the receipt of any such notice, the Company will promptly,
but no later than four weeks after receipt of such notice, file a new
registration statement pursuant to the Act, so that such designated Registrable
Securities may be publicly sold under the Act as promptly as practicable
thereafter and the Company will use reasonable
<PAGE>
efforts to cause such registration to become and remain effective (including the
taking of such reasonable steps as are necessary to obtain the removal of any
stop order), provided, that such Holder shall furnish the Company with
appropriate information in connection therewith as the Company may reasonably
request in writing. The 50% Holder may, at its option, request the registration
of any of the shares of Common Stock underlying this Warrant in a registration
statement made by the Company as contemplated by Section 6(a) or in connection
with a request made pursuant to this Section 6(b) prior to acquisition of the
shares of Common Stock issuable upon exercise of this Warrant. Within ten (10)
days after receiving any such notice pursuant to this Section 6(b), the Company
shall give notice to any other Holders of this Warrant, advising that the
Company is proceeding with such registration statement and offering to include
therein such securities underlying that part of the Warrants held by the other
Holders, provided that they shall furnish the Company with such appropriate
information (relating to the intentions of such Holders) in connection therewith
as the Company shall reasonably request in writing. All costs and expenses of
the first new registration statement filed in accordance with this Section 6(b)
shall be borne by the Company, except that the Holder(s) shall bear the fees of
their own counsel and any other advisors retained by them and any underwriting
discounts or commissions applicable to any of the securities sold by them. All
costs and expenses of the second such new registration statement shall be borne
by the Holder(s). The Company shall use its best efforts to cause any
registration statement filed pursuant to this Section 6(b) that is declared
effective to remain effective and shall maintain a current prospectus relating
thereto until all Registrable Securities have been sold or are freely saleable
without restriction under Rule 144 (or its successor). The Company shall supply
prospectuses, and such other documents as the Holder(s) may reasonably request
in order to facilitate the public sale or other disposition of the Registrable
Securities, use its best efforts to register and qualify any of the Registrable
Securities for sale in such states (i) as such Holder(s) designate and (ii) with
respect to which the Company obtained a qualification in connection with its
initial public offering and furnish indemnification in the manner provided in
Section 7 hereof. Notwithstanding the foregoing, the Company shall not be
required to include in any registration statement any Registrable Securities
which in the opinion of counsel to the Company (which opinion is reasonably
acceptable to counsel to the Representative) would be salable immediately
without restriction under Rule 144 (or its successor) if the Warrant was
exercised pursuant to Section 2(b) herein.

            (c) The term "50% Holder" as used in this Section 6 shall mean the
Holder(s) of at least 50% of the shares Common Stock issued or issuable upon
exercise of the Warrant issued in connection with the Consulting Agreement.

            (d) The Company shall have the right to terminate or withdraw any
registration initiated by the Company under Section 6(a) hereof prior to the
effectiveness thereof whether or not any Holder (including permitted
transferees) has elected to include Registrable Securities in such registration.
Any such termination or withdrawal shall not otherwise affect Holder(s) rights
under this Section 6.

      7. (a) Whenever pursuant to Section 6 a registration statement relating to
any of the shares of Common Stock issuable upon the exercise of this Warrant is
filed under the Act, amended or supplemented, the Company will indemnify and
hold harmless each Holder of the shares of Common Stock covered by such
registration statement, amendment or supplement (such Holder being hereinafter
called the "Distributing Holder"), and each person, if any, who controls (within
the meaning of the Act or the Securities Exchange Act of 1934 (the "Exchange
Act")) the Distributing Holder against any losses, claims, damages or
liabilities, joint or several, to which the Distributing Holder or any such
controlling person may become subject, under the Act, the Exchange Act or
otherwise insofar as such losses, claims, damages or liabilities, or actions in
respect thereof, arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any such registration
statement as declared effective or any final prospectus constituting a part
thereof or any amendment or supplement thereto, or arise out of or are based
upon the omission or
<PAGE>
the alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading,and will
reimburse the Distributing Holder or such controlling person for any legal or
other expense reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the Company will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
said registration statement, preliminary prospectus, final prospectus or
amendment or supplement in reliance upon and in conformity with written
information furnished by such Distributing Holder for use in the preparation
thereof and provided further, that the indemnity agreement provided in this
Section 7(a) with respect to any preliminary prospectus shall not inure to the
benefit of any Distributing Holder or controlling person of such Distributing
Holder from whom the person asserting any losses, claims, charges, liabilities
or litigation based upon any untrue statement or alleged untrue statement of a
material fact or omission or alleged omission to state therein a material fact,
received such preliminary prospectus, if a copy of the prospectus in which such
untrue statement or alleged untrue statement or omission or alleged omission was
corrected has not been sent or given to such person within the time required by
the Act and the Rules and Regulations thereunder.

            (b) The Distributing Holder will indemnify and hold harmless the
Company, each of its directors, each of its officers who have signed said
registration statement and such amendments and supplements thereto, and each
person, if any, who controls the Company (within the meaning of the Act) against
any losses, claims, damages or liabilities, joint or several, to which the
Company or any such director, officer or controlling person may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities, or actions in respect thereof, arise out of or are based upon any
untrue or alleged untrue statement of any material fact contained in said
registration statement, preliminary prospectus, final prospectus, or amendment
or supplement, or arise out of or are based upon the omission or the alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such loss, claim, damage or liability
arises out of or is based upon an untrue-statement or alleged untrue statement
or omission or alleged omission made in said registration statement, said
preliminary prospectus, said final prospectus or said amendment or supplement in
reliance upon and in conformity with written information furnished by such
Distributing Holder for use in the preparation thereof; and will reimburse the
Company or any such director, officer or controlling person for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action.

            (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against any indemnifying
party, give the indemnifying party notice of the commencement thereof, but the
omission so to notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party otherwise than under this
Section 7.

            (d) In case any such action is brought against any indemnified
party, and it notifies an indemnifying party of the commencement hereof, the
indemnifying party will be entitled to participate in and, to the extent that it
may wish, jointly with any other indemnifying party similarly notified, to
assume the defense thereof, with counsel reasonably satisfactory to such
indemnified party, and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such indemnified party under this
Section 7 for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation.
<PAGE>
      8. The Exercise Price in effect at the time and the number and kind of
securities purchasable upon the exercise of this Warrant shall be subject to
adjustment from time to time upon the happening of certain events as follows:

            (a) In case the Company shall (i) declare a dividend or make a
distribution on its outstanding shares of Common Stock in shares of Common
Stock, (ii) subdivide or reclassify its outstanding shares of Common Stock into
a greater number of shares, (iii) combine or reclassify its outstanding shares
of Common Stock into a smaller number of shares, or (iv) enter into any
transaction whereby this Warrant or the outstanding shares of Common Stock of
the Company are at any time changed into or exchanged for a different number or
kind of shares or other security of the Company or of another corporation
through reorganization, merger, consolidation, liquidation or recapitalization,
then appropriate adjustments in the number of shares of Common Stock (or other
securities for which such shares have previously been exchanged or converted)
subject to this Warrant shall be made and the Exercise Price in effect at the
time of the record date for such dividend or distribution or of the effective
date of such subdivision, combination, reclassification, reorganization, merger,
consolidation, liquidation or recapitalization shall be proportionately adjusted
so that the Holder of this Warrant exercised after such date shall be entitled
to receive the aggregate number and kind of shares of Common Stock which, if
this Warrant had been exercised by such Holder immediately prior to such date,
it would have been entitled to receive upon such dividend, distribution,
subdivision, combination, reclassification, reorganization, merger,
consolidation, liquidation or recapitalization. Such adjustment shall be made
successively whenever any event listed above shall occur.

            (b) In case the Company shall fix a record date for the issuance of
rights or warrants to all holders of its Common Stock entitling them to
subscribe for or purchase shares of Common Stock (or other securities
convertible into Common Stock) at a price (the "Subscription Price") less than
the Exercise Price on a per share basis (the "Per Share Exercise Price") on such
record date, the Exercise Price shall be adjusted so that the same shall equal
the price determined by multiplying the Per Share Exercise Price in effect
immediately prior to the date of issuance by a fraction, the numerator of which
shall be the sum of the number of shares of Common Stock outstanding on the
record date mentioned below and the number of additional shares of Common Stock
which the aggregate offering price of the total number of shares of Common Stock
so offered (or the aggregate conversion price of the convertible securities so
offered) would purchase at the Per Share Exercise Price in effect immediately
prior to the date of such issuance, and the denominator of which shall be sum of
the number of shares of Common Stock outstanding on the record date mentioned
below and the number of additional shares of Common Stock offered for
subscription or purchase (or into which the other convertible securities so
offered are convertible). Such adjustment shall be made successively whenever
such rights or warrants are issued and shall become effective immediately after
the record date for the determination of shareholders entitled to receive such
rights or warrants; and to the extent that shares of Common Stock are not
delivered (or other securities convertible into Common Stock are not delivered)
after the expiration of such rights or warrants the Exercise Price shall be
readjusted to the Exercise Price which would then be in effect had the
adjustments made upon the issuance of such rights or warrants been made upon the
basis of deliver of only the number of shares of Common Stock (or other
securities convertible into Common Stock) actually delivered.

            (c) In case the Company shall hereafter distribute to all holders of
its Common Stock evidences of its indebtedness or assets (excluding cash
dividends or distributions and dividends or distributions referred to in
Subsection 8(a) above) or subscription rights or warrants (excluding those
referred to in Subsection 8(b) above), then in each such case the Exercise Price
in effect thereafter shall be determined by multiplying the Per Share Exercise
Price in effect immediately prior thereto by a fraction, the numerator of which
shall be the total number of shares of Common Stock then outstanding multiplied
by the current market price per share of Common Stock (as defined in Subsection
8(e) below), less the fair market value (as determined by the Company's Board
<PAGE>
of Directors) of said assets, or evidences of indebtedness so distributed or of
such rights or warrants, and the denominator of which shall be the total number
of shares of Common Stock outstanding multiplied by such current market price
per share of Common Stock. Such adjustment shall be made whenever any such
distribution is made and shall become effective immediately after the record
date for the determination of shareholders entitled to receive such
distribution.

            (d) Whenever the Exercise Price payable upon exercise of this
Warrant is adjusted pursuant to Subsections 8(a), 8(b) or 8(c) above, the number
of shares of Common Stock purchasable upon exercise of this Warrant shall
simultaneously be adjusted by multiplying the number of shares of Common Stock
issuable upon exercise of this Warrant by the Exercise Price in effect on the
date hereof and dividing the product so obtained by the Exercise Price, as
adjusted.

            (e) For the purpose of any computation under Subsection 8(c) above,
the current market price per share of Common Stock at any date shall be
determined as set forth in Section 2(b) herein.

            (f) No adjustment in the Exercise Price shall be required unless
such adjustment would require an increase or decrease of at least five cents
($0.05) in such price; provided, however, that any adjustments which may by
reason of this Subsection 8(f) are not required to be made shall be carried
forward and taken into account in any subsequent adjustment required to be made
hereunder. All calculations under this Section 8 shall be made to the nearest
cent or to the nearest one-hundredth of a share, as the case may be. Anything in
this Section 8 to the contrary notwithstanding, the Company shall be entitled,
but shall not be required, to make such changes in the Exercise Price, in
addition to those required by this Section 8, as it shall determine, in its sole
discretion, to be advisable in order that any dividend or distribution in shares
of Common Stock, or any subdivision, reclassification or combination of Common
Stock, hereafter made by the Company shall not result in any Federal income tax
liability to the holders of the Common Stock or other securities convertible
into Common Stock.

            (g) Whenever the Exercise Price is adjusted, as herein provided, the
Company shall promptly cause a notice setting forth the adjusted Exercise Price
and adjusted number of shares of Common Stock issuable upon exercise of this
Warrant to be mailed to the Holder, at its address set forth herein, and shall
cause a certified copy thereof to be mailed to the Company's transfer agent, if
any. The Company may retain a firm of independent certified public accountants
selected by the Board of Directors (who may be the regular accountants employed
by the Company) to make any computation required by this Section 8, and a
certificate signed by such firm shall be conclusive evidence of the correctness
of such adjustment.

            (h) In the event that at any time, as a result of an adjustment made
pursuant to the provisions of this Section 8, the Holder of this Warrant
thereafter shall become entitled to receive any shares of the Company other than
Common Stock, thereafter the number of such other shares so receivable upon
exercise of this Warrant shall be subject to adjustment from time to time in a
manner and on terms as nearly equivalent as practicable to the provisions with
respect to the Common Stock contained in Subsections 8(a) to 8(f), inclusive,
above.

      9. This Agreement shall be governed by and in accordance with the laws of
the State of Washington without regard to conflict of laws provision.

This Warrant is issued upon transfer in whole of Warrant No. F-1, originally
issued as of May 17, 2002.

      IN WITNESS WHEREOF, CRAY INC. has caused this Warrant to be signed by
its duly authorized officers.
