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.

Item 6. Indemnification of Director and Officers.

Article XII of the Company's Articles of Incorporation and Section 11 of the Company's 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.08.000 of the WBCA 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 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 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 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.


SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, as 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 March 29, 2001.

Exhibit 4.1

CRAY INC.

1999 STOCK OPTION PLAN

1. Purpose. The purpose of the 1999 Stock Option Plan (the "Plan") is to enable Cray Inc. (the "Company") to attract, reward and retain the services or advice of the Company's current or future employees, officers, directors, agents and consultants, and to provide added incentives to them by encouraging stock ownership in the Company.

2. Stock Subject to This Plan. Subject to adjustment as provided below and in Section 6 hereof, the stock subject to this Plan shall consist of shares of the Company's common stock (the "Common Stock"), and the total number of shares of Common Stock to be delivered upon the exercise of all options granted under this Plan shall not exceed 6,000,000 shares, as such Common Stock was constituted on the effective date of this Plan. If any option granted under this Plan shall expire, be surrendered, exchanged for another option, cancelled or terminated for any reason without having been exercised in full, the unpurchased shares subject to such option shall again be available for purposes of this Plan, including for replacement options which may be granted in exchange for such surrendered, cancelled or terminated options. Shares issued upon exercise of options granted under this Plan may be subject to such restrictions on transfer, repurchase rights or other restrictions as may be determined by the Board.

3. Administration. This Plan shall be administered by the Board of Directors of the Company (the "Board"). The Board may suspend, amend or terminate this Plan as provided in Section 8.

3.1 Powers. Subject to the specific provisions of this Plan, the Board shall have the authority, in its discretion from time to time: (a) to grant the stock options described in Section 5, including Incentive Stock Options and Non-Qualified Stock Options, and to designate each option granted as an Incentive Stock Option or a Non-Qualified Stock Option; (b) to determine, in accordance with Section 5.1(f) of this Plan, the fair market value of the shares of Common Stock subject to options; (c) to determine the exercise price per share of options; (d) to determine the Optionees (as defined herein) to whom, and the time or times at which, options shall be granted and the number of shares of Common Stock to be represented by each option; (e) to interpret this Plan; (f) to prescribe, amend and rescind rules and regulations relating to this Plan; (g) to determine the terms and provisions of each option granted (which need not be identical) and, with the consent of the holder thereof, modify or amend each option; (h) to reduce the exercise price per share of outstanding and unexercised options; (i) to


defer, with the consent of the Optionee, or to accelerate the exercise date of any option; (j) to waive or modify any term or provision contained in any option applicable to the underlying shares of Common Stock; (k) to authorize any person to execute on behalf of the Company any instrument required to effectuate the grant of an option previously granted by the Board; (l) to correct any defect or supply any omission or reconcile any inconsistency in the Plan or in any stock option agreement in the manner and to the extent it shall deem expedient to carry the Plan into effect; and (m) to make all other determinations deemed necessary or advisable for the administration of this Plan. The interpretation and construction by the Board of any terms or provisions of this Plan, any option issued hereunder or of any rule or regulation promulgated in connection herewith and all actions taken by the Board shall be conclusive and binding on all interested parties. The Board may delegate administrative functions to individuals who are officers or employees of the Company.

3.2 Limited Liability. No member of the Board or officer of the Company shall be liable for any action or inaction of the entity or body, or another person or, except in circumstances involving bad faith, of himself or herself. Subject only to compliance with the explicit provisions hereof, the Board may act in its absolute discretion in all matters related to this Plan.

3.3 Securities Exchange Act of 1934. At any time that the Company has a class of securities registered pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), this Plan shall be administered by the Board in accordance with Rule 16b-3 adopted under the Exchange Act, as such rule may be amended from time to time.

3.4 Committee. The Board by resolution may delegate to a committee of the Board consisting of one or more members (the "Committee") any or all authority for administration of the Plan. If a Committee is appointed, all references to the Board of Directors in the Plan shall mean and relate to such Committee, except that only the Board of Directors may amend, modify, suspend or terminate the Plan as provided in Section 8.

4. Eligibility. The Board may award options to any current or future employee, officer, director, agent or consultant of the Company. Any party to whom an option is granted under this Plan is referred to as an "Optionee."

5. Awards. The Board, may take the following actions from time to time, separately or in combination, under this Plan: (a) grant Incentive Stock Options, as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), to any employee of the Company or its subsidiaries, as provided in Section 5.1 of this Plan; (b) grant options other than Incentive Stock Options ("Non-Qualified Stock Options"), as provided in Section 5.2 of this Plan; (c) grant

10

options to officers, employees and others in foreign jurisdictions, as provided in Section 5.7 of this Plan; and (d) grant options in certain acquisition transactions, as provided in Section 5.8 of this Plan. No person may be granted options to acquire more than 300,000 shares of Common Stock in any fiscal year of the Company.

5.1 Incentive Stock Options. Incentive Stock Options shall be subject to the following terms and conditions:

(a) Incentive Stock Options may be granted under this Plan only to employees of the Company or its subsidiaries, including employees who are directors.

(b) No employee may be granted Incentive Stock Options under this Plan to the extent that the aggregate fair market value, on the date of grant, of the Common Stock with respect to which Incentive Stock Options are exercisable for the first time by that employee during any calendar year, under this Plan and under any other incentive stock option plan (within the meaning of
Section 422 of the Code) of the Company or any subsidiary, exceeds $100,000. To the extent that any option designated as an Incentive Stock Option exceeds the $100,000 limit, such option shall be treated as a Non-Qualified Stock Option. In making this determination, options shall be taken into account in the order in which they were granted, and the fair market value of the shares of Common Stock shall be determined as of the time that the option with respect to such shares was granted.

(c) An Incentive Stock Option may be granted under this Plan to an employee possessing more than 10% of the total combined voting power of all classes of stock of the Company (as determined pursuant to the attribution rules contained in Section 424(d) of the Code) only if the exercise price is at least 110% of the fair market value of the Common Stock subject to the option on the date the option is granted, as described in Section 5.1(f) of this Plan, and only if the option by its terms is not exercisable after the expiration of five years from the date it is granted.

(d) Except as provided in Section 5.5 of this Plan, no Incentive Stock Option granted under this Plan may be exercised unless at the time of such exercise the Optionee is employed by the Company or any subsidiary of the Company and the Optionee has been so employed continuously since the date such option was granted.

(e) Subject to Sections 5.1(c) and 5.1(d) of this Plan, Incentive Stock Options granted under this Plan shall continue in effect for the period fixed by the Board, except that no Incentive Stock Option shall be exercisable after the

11

expiration of 10 years from the date it is granted.

(f) The exercise price shall not be less than 100% of the fair market value of the shares of Common Stock covered by the Incentive Stock Option at the date the option is granted. The fair market value of shares shall be the closing price per share of the Common Stock on the date of grant as reported on a securities quotation system or stock exchange or other principal market for the Common Stock. If such shares are not so reported or listed, the Board shall from time to time determine the fair market value of the shares of Common Stock in its discretion.

(g) The provisions of clauses (b) and (c) of this Section shall not apply if either the applicable sections of the Code or the regulations thereunder are amended so as to change or eliminate such limitations or to permit appropriate modifications of those requirements by the Board.

5.2 Non-Qualified Stock Options. Non-Qualified Stock Options shall be subject to the following terms and conditions:

(a) The exercise price may be more or less than or equal to the fair market value of the shares of Common Stock covered by the Non-Qualified Stock Option on the date the option is granted, and the exercise price may fluctuate based on criteria determined by the Board. The fair market value of shares of Common Stock covered by a Non-Qualified Stock Option shall be determined by the Board, as described in Section 5.1(f).

(b) Unless otherwise established by the Board, any Non-Qualified Stock Option shall terminate 10 years after the date it is granted.

5.3 Vesting. To ensure that the Company will achieve the purposes of and receive the benefits contemplated in this Plan, the Board, at its discretion, may establish a vesting schedule, change such vesting schedule or provide for no vesting schedule for options granted under the Plan. In establishing a vesting schedule, the Board may set a "Base Date", meaning a reference date for the specific option grant and Optionee. If no Base Date is established by the Board for a specific option grant, then the date of grant of the option by the Board shall constitute the Base Date.

5.4 Nontransferability. Each option granted under this Plan and the rights and privileges conferred hereby may not be transferred, assigned, pledged or hypothecated in any manner (whether by operation of law or otherwise) other than by will or by the applicable laws of descent and distribution or pursuant to a qualified domestic relations order. The foregoing notwithstanding, the Board on conditions it determines may permit the transferability of a Non-Qualified

12

Stock Option by an Optionee solely to members of the Optionee's family members or to one or more trusts or partnerships for the benefit of such family members. Any purported transfer or assignment in violation of this provision shall be void.

5.5 Termination of Options.

5.5.1 Generally. Unless otherwise determined by the Board or specified in the Optionee's Option Agreement, if the Optionee's employment or service with the Company terminates for any reason other than for cause, resignation, retirement, disability or death, and unless by its terms the option sooner terminates or expires, then the Optionee may exercise, for a three-month period, that portion of the Optionee's option which was exercisable at the time of such termination of employment or service (provided the conditions of Section 5.6.4 and any other conditions specified in the Option Agreement shall have been met by the date of exercise of such option).

5.5.2 For Cause; Resignation.

(a) If an Optionee is terminated for cause or resigns in lieu of dismissal, any option granted hereunder shall be deemed to have terminated as of the time of the first act which led or would have led to the termination for cause or resignation in lieu of dismissal, and such Optionee shall thereupon have no right to purchase any shares of Common Stock pursuant to the exercise of such option, and any such exercise shall be null and void. Termination for "cause" shall include (i) the violation by the Optionee of any reasonable rule or policy of the Board of Directors or the Optionee's superiors or the chief executive officer or the President of the Company that results in damage to the Company or which, after notice to do so, the Optionee fails to correct within a reasonable time; (ii) any willful misconduct or gross negligence by the Optionee in the responsibilities assigned to him or her; (iii) any willful failure to perform his or her job as required to meet the objectives of the Company; (iv) any wrongful conduct of an Optionee which has an adverse impact on the Company or which constitutes a misappropriation of the assets of the Company; (v) unauthorized disclosure of confidential information; or (vi) the Optionee's performing services for any other company or person which competes with the Company while he or she is employed by or provides services to the Company, without the prior written approval of the Chairman or President of the Company. "Resignation in lieu of dismissal" shall mean a resignation by an Optionee of employment with or service to the Company if (i) the Company has given prior notice to such Optionee of its intent to dismiss the Optionee for circumstances that constitute cause, or (ii) within two months of the Optionee's resignation, the Chairman or President of the Company or the Board of Directors determines, which determination shall be final and binding, that such resignation was related to an

13

act which would have led to a termination for cause.

(b) If an Optionee resigns from the Company, the right of the Optionee to exercise his or her option shall be suspended for a period of two months from the date of resignation, unless the Chairman or the President of the Company or the Board of Directors determines otherwise in writing. Thereafter, unless there is a determination that the Optionee resigned in lieu of dismissal, the option may be exercised at any time prior to the earlier of (i) the expiration date of the option (which shall have been similarly suspended) or (ii) the expiration of three months after the date of resignation, for that portion of the Optionee's option which was exercisable at the time of such resignation (provided the conditions of Section 5.6.4 and any other conditions specified in the Option Agreement shall have been met at the date of exercise of such option).

5.5.3 Retirement. Unless otherwise determined by the Board, if an Optionee's employment or service with the Company is terminated with the Company's approval for reasons of age, the Option may be exercised at any time prior to the earlier of (a) the expiration date of the option or (b) the expiration of three months after the date of such termination of employment or service, for that portion of the Optionee's option which was exercisable at the time of such termination of employment or service (provided the conditions of
Section 5.6.4 and any other conditions specified in the Option Agreement shall have been met at the date of exercise of such option).

5.5.4 Disability. Unless otherwise determined by the Board, if an Optionee's employment or relationship with the Company terminates because of a permanent and total disability (as defined in Section 22(e)(3) of the Code), the Option may be exercised at any time prior to the earlier of (a) expiration date of the Option or (b) the expiration of 12 months after the date of such termination for up to the full number of shares of Common Stock covered thereby, including any portion not yet vested (provided the conditions of Section 5.6.4 and any other conditions specified in the Option Agreement shall have been met by the date of exercise of such Option).

5.5.5 Death. Unless otherwise determined by the Board, in the event of the death of an Optionee while employed by or providing service to the Company, the Option may be exercised at any time prior to the earlier of (a) the expiration date of the Option or (b) the expiration of 12 months after the date of death by the person or persons to whom such Optionee's rights under the option shall pass by the Optionee's will or by the applicable laws of descent and distribution for up to the full number of shares of Common Stock covered thereby, including any portion not yet vested (provided the conditions of
Section 5.6.4 and any other conditions specified in the Option Agreement shall have been met by the date of exercise of such Option).

14

5.5.6 Extension of Exercise Period. The Board, at the time of grant or at any time thereafter, may extend the three-month and 12-month exercise periods to any length of time not longer than the original expiration date of the option, and may increase the portion of an option that is exercisable, subject to such terms and conditions as the Board may determine; provided, that any extension of the exercise period or other modification of an Incentive Stock Option shall be subject to the written agreement and acknowledgment by the Optionee that the extension or modification disqualifies the option as an Incentive Stock Option.

5.5.7 Failure to Exercise Option. To the extent that the option of any deceased Optionee or of any Optionee whose employment or service terminates is not exercised within the applicable period, all rights to purchase shares of Common Stock pursuant to such options shall cease and terminate.

5.5.8 Leaves. For purposes of this Section 5.5, with respect to Incentive Stock Options, employment shall be deemed to continue while the Optionee is on military leave, sick leave or other bona fide leave of absence (as determined by the Board) in accordance with the policies of the Company.

5.6 Exercise.

5.6.1 Procedure. Subject to the provisions of Section 5.3 above, each Option may be exercised in whole or in part; provided, however, that no fewer than 100 shares (or the remaining shares then purchasable under the Option, if less than 100 shares) may be purchased upon any exercise of any Option granted hereunder and that only whole shares will be issued pursuant to the exercise of any Option (the number of 100 shares shall not be changed by any transaction or action described in Section 6 unless the Board determines that such a change is appropriate). Options shall be exercised by delivery to the Secretary of the Company or his or her designated agent of written notice of the number of shares with respect to which the Option is exercised, together with payment in full of the exercise price.

5.6.2 Payment. Payment of the option exercise price shall be made in full at the time the written notice of exercise of the option is delivered to the Secretary of the Company or his or her designated agent and shall be in cash or check or pursuant to irrevocable instructions to a stock broker to deliver the amount of sales proceeds necessary to pay the appropriate exercise price and withholding tax obligations, all in accordance with applicable governmental regulations, for the shares of Common Stock being purchased. The Board may determine at the time the option is granted for Incentive Stock Options, or at any

15

time before exercise for Non-Qualified Stock Options, that additional forms of payment will be permitted, including without limitation full recourse promissory notes. In addition, with the prior consent of the Board, an Optionee may deliver previously owned shares of Common Stock or apply automatically the shares to be received upon the exercise of a portion of a stock option (even though stock certificates have not yet been issued) to satisfy the purchase price for additional portions of the option.

5.6.3 Withholding. Prior to the issuance of shares of Common Stock upon the exercise of an option, the Optionee shall pay to the Company the amount of any applicable federal, state or local tax withholding obligations. The Company may withhold any distribution in whole or in part until the Company is so paid. The Company shall have the right to withhold such amount from any other amounts due or to become due from the Company, as the case may be, to the Optionee, including salary (subject to applicable law) or to retain and withhold a number of shares having a market value not less than the amount of such taxes required to be withheld by the Company to reimburse it for any such taxes and cancel (in whole or in part) any such shares so withheld.

5.6.4 Conditions Precedent to Exercise. The Board may establish conditions precedent to the exercise of any option, which shall be described in the relevant Option Agreement.

5.7 Foreign Qualified Grants. Options under this Plan may be granted to officers and employees of the Company and other persons described in Section 4 who reside in foreign jurisdictions as the Board may determine from time to time. The Board may adopt such supplements to the Plan as are necessary to comply with the applicable laws of such foreign jurisdictions and to afford Optionees favorable treatment under such laws; provided, however, that no award shall be granted under any such supplement on terms which are more beneficial to such Optionees than the terms permitted by this Plan.

5.8 Corporate Mergers, Acquisitions, Etc. The Board may also grant options under this Plan having terms, conditions and provisions that vary from those specified in this Plan provided that such options are granted in substitution for, or in connection with the assumption of, existing options granted, awarded or issued by another corporation and assumed or otherwise agreed to be provided for by the Company pursuant to or by reason of a transaction involving a corporate merger, consolidation, acquisition of property or stock, reorganization or liquidation to which the Company is a party.

5.9 Holding Period. Unless otherwise determined by the Board, if a person subject to Section 16 of the Exchange Act exercises an option within six months of the date of grant of the option, the shares of Common Stock acquired

16

upon exercise of the option may not be sold until six months after the date of grant of the option.

5.10 Option Agreements. Options granted under this Plan shall be evidenced by written stock option agreements ("Option Agreements") which shall contain such terms, conditions, limitations and restrictions as the Board shall deem advisable and which are consistent with this Plan. All Option Agreements shall include or incorporate by reference the applicable terms and conditions contained in this Plan.

6. Adjustments Upon Changes in Capitalization.

6.1 Stock Splits, Capital Stock Adjustments. The aggregate number and class of shares for which options may be granted under this Plan, the number and class of shares covered by each outstanding option and the exercise price per share thereof (but not the total price), and each such option, shall all be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock of the Company resulting from a stock split, stock dividend or consolidation of shares or any like capital stock adjustment.

6.2 Effect of Merger, Sale of Assets, Liquidation or Dissolution.

6.2.1 Termination Unless Assumption or Substitution. Upon the effective date of a merger, consolidation or plan of exchange (other than a merger, consolidation or plan of exchange involving the Company in which the holders of voting securities of the Company immediately prior to such transaction own at least 50% of the voting power of the outstanding securities of the surviving corporation or a parent of the surviving corporation after such transaction), or a sale of all or substantially all the assets of the Company, or a liquidation or dissolution of the Company, the Plan and any option theretofore granted hereunder shall terminate, unless provisions be made in writing in connection with such transaction for the continuance of the Plan and for the assumption of options theretofore granted, or the substitution for such options, with new options covering the shares of a successor corporation, or a parent, affiliate or subsidiary thereof, with appropriate adjustments as to number and kind of shares and prices thereof, in which event the Plan and the options granted under it, or the new options substituted therefor, shall continue in the manner and under the terms so provided.

6.2.2 Exercise and Vesting. If provision is not made pursuant to the preceding Section 6.2(a) in connection with such a transaction for the continuance of the Plan and for the assumption of options, or the substitution for such options of new options covering the shares of a successor employer corporation or a parent, affiliate or subsidiary thereof, then each Optionee

17

under the Plan shall be entitled, prior to the effective date of any such transaction, to exercise the option for the full number of shares covered thereby, including any portion not yet vested (provided that the conditions of
Section 5.6.4 and any other conditions specified in the Option Agreement shall have been met at the date of exercise of such option).

6.3 Fractional Shares. In the event of any adjustment in the number of shares covered by any option, any fractional shares resulting from such adjustment shall be disregarded and each such option shall cover only the number of full shares resulting from such adjustment.

6.4 Determination of Board to Be Final. All adjustments under this
Section 6 shall be made by the Board of Directors, and its determination as to what adjustments shall be made, and the extent thereof, shall be final, binding and conclusive. Unless an Optionee agrees otherwise, any change or adjustment to an Incentive Stock Option shall be made, if possible, in such a manner so as not to constitute a "modification," as defined in Section 424(h) of the Code, and so as not to cause the Optionee's Incentive Stock Option to fail to continue to qualify as an Incentive Stock Option.

7. Securities Regulations.

7.1 Compliance with Law. Shares of Common Stock shall not be issued with respect to an option granted under this Plan unless the exercise of such option and the issuance and delivery of such shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, any applicable state securities laws, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, applicable laws of foreign countries and other jurisdictions and the requirements of any quotation service or stock exchange upon which the shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance, including the availability of an exemption from registration for the issuance and sale of any shares hereunder. The inability of the Company to obtain, from any regulatory body having jurisdiction, the authority deemed by the Company's counsel to be necessary for the lawful issuance and sale of any shares hereunder or the unavailability of an exemption from registration for the issuance and sale of any shares hereunder shall relieve the Company of any liability with respect of the nonissuance or sale of such shares as to which such requisite authority shall not have been obtained.

7.2 Investment Purpose. As a condition to the exercise of an option, the Company may require the Optionee to represent and warrant at the time of any such exercise that the shares of Common Stock are being purchased only for investment and without any present intention to sell or distribute such shares if,

18

in the opinion of counsel for the Company, such a representation is required by any relevant provision of the aforementioned laws. The Company may place a stop-transfer order against any shares of Common Stock on the official stock books and records of the Company, and a legend may be stamped on stock certificates to the effect that the shares of Common Stock may not be pledged, sold or otherwise transferred unless an opinion of counsel is provided (concurred in by counsel for the Company) stating that such transfer is not in violation of any applicable law or regulation. The Board may also require such other action or agreement by the Optionees as may from time to time be necessary to comply with the federal and state securities laws. THIS PROVISION SHALL NOT OBLIGATE THE COMPANY TO UNDERTAKE REGISTRATION OF THE OPTIONS OR STOCK THEREUNDER.

8. Amendment and Termination.

8.1 Plan. The Board of Directors may at any time suspend, amend or terminate this Plan, provided that, except as set forth in Section 6, the approval of the Company's shareholders is necessary within 12 months before or after the adoption by the Board of Directors of any amendment that will:

(b) permit the granting of stock options to a class of persons other than those presently permitted to receive stock options under this Plan; or

8.2 Options. Subject to the requirements of Section 422 of the Code with respect to Incentive Stock Options and to the terms and conditions and within the limitations of this Plan, the Board may modify or amend outstanding options granted under this Plan. The modification or amendment of an outstanding option shall not, without the consent of the Optionee, impair or diminish any of his or her rights or any of the obligations of the Company under such option. Except as otherwise provided in this Plan, no outstanding option shall be terminated without the consent of the Optionee. Unless the Optionee agrees otherwise, any changes or adjustments made to outstanding Incentive Stock Options granted under this Plan shall be made in such a manner so as not to constitute a "modification," as defined in Section 424(h) of the Code, and so as not to cause any Incentive Stock Option issued hereunder to fail to continue to qualify as an Incentive Stock Option as defined in Section 422(b) of the Code.

19

8.3 Automatic Termination. Unless sooner terminated by the Board of Directors, this Plan shall terminate ten years from the date on which this Plan is adopted by the Board. No option may be granted after such termination or during any suspension of this Plan. The amendment or termination of this Plan shall not, without the consent of the Optionee, alter or impair any rights or obligations under any option theretofore granted under this Plan.

9.2 No Status as Shareholder. Neither the Optionee nor any party to which the Optionee's rights and privileges under the option may pass shall be, or have any of the rights or privileges of, a shareholder of the Company with respect to any of the shares of Common Stock issuable upon the exercise of any option granted under this Plan unless and until such option has been exercised and the issuance (as evidenced by the appropriate entry on the books of the Company or duly authorized transfer agent of the Company) of the stock certificate evidencing such shares.

9.3 Status as an Employee. Nothing in this Plan or in any option granted pursuant to this Plan shall confer upon any Optionee any right to continue in the employ of the Company, or to interfere in any way with the right of the Company to terminate his or her employment or other relationship with the Company at any time.

9.4 Reservation of Shares. The Company, during the term of this Plan, at all times will reserve and keep available such number of shares of Common Stock as shall be sufficient to satisfy the requirements of this Plan.

10. Effectiveness of This Plan. This Plan shall become effective upon adoption by the Board so long as it is approved by the Company's shareholders any time within 12 months after the adoption of this Plan. No option granted under this Plan to any officer or director of the Company shall become exercisable, however, until the Plan is approved by the shareholders, and any options granted prior to such approval shall be conditioned upon and are subject to such approval.

(b) If an Optionee resigns from the Company, the right of the Optionee to exercise his or her stock option shall be suspended for a period of two months from the date of resignation, unless the President or chief executive officer of the Company or the Board determines otherwise in writing. Thereafter, unless there is a determination that the Optionee resigned in lieu of dismissal, the stock option may be exercised at any time prior to the earlier of (i) the expiration date of the stock option (which shall have been similarly suspended) or (ii) the expiration of three months after the date of resignation, for that portion of the Optionee's stock option that was exercisable at the time of such resignation (provided the conditions of Section 5.5.4 and any other conditions specified in the option agreement shall have been met at the date of exercise of such stock option).

(a) the expiration date of the stock option or (b) the expiration of 12 months after the date of death by the person or persons to whom such Optionee's rights under the stock option shall pass by the Optionee's will or by the applicable laws of descent and distribution for up to the full number of shares of Common Stock covered thereby, including any portion not yet vested (provided the conditions of Section 5.5.4 and any other conditions specified in the option agreement shall have been met by the date of exercise of such stock option).

5.4.6 Extension of Exercise Period Applicable to Termination. The Board, at the time of grant or at any time thereafter, may extend the three-month and 12-month exercise periods to any length of time not longer than the original expiration date of the stock option, and may increase the portion of a stock option that is exercisable, subject to such terms and conditions as the Board may determine.

The Board of Directors
CRAY INC.

Dear Sirs:

I am the general counsel of Cray Inc. (the "Company") and have supervised the corporate proceedings in connection with the filing of a Registration Statement on Form S-8 (the "Registration Statement") under the Securities Act of 1933 relating to the issuance of an aggregate of three million shares of Common Stock (the "Shares") of the Company pursuant to the Company's 1999 Stock Option Plan and the 2000 Non-Executive Employee Stock Option Plan (the "Plans"). I have reviewed the corporate actions of the Company in connection with this matter and have examined those documents, corporate records, and other instruments that I deemed necessary for the purposes of this opinion.

Based on the foregoing, it is my opinion that the Shares have been duly authorized and, when issued pursuant to the Plans, will be legally issued, fully paid and nonassessable.

Very truly yours,

/s/
