  an affiliate to issue a standby letter of credit for the account of Borrower
  and for the benefit of Safety National in the original principal amount of Three
  Hundred Fifty Thousand Dollars ($350,000.00) (the “Standby Letter of Credit”).
  The Standby Letter of Credit has an expiration date of October 1, 2003, and
  is subject to the additional terms of a letter of credit agreement, application
  and all related documents required by Bank in connection with the issuance thereof
  (collectively, the “Letter of Credit Agreement”). Subject to the terms and conditions
  of this Agreement, Bank hereby confirms that the Standby Letter of Credit remains
  in full force and effect. 

      (b)    
  Repayment of
  Drafts. Each drawing paid under the Standby Letter of
  Credit shall be repaid by Borrower in accordance with the provisions of the
  Letter of Credit Agreement. 

     
  SECTION 1.4.     INTEREST/FEES. 

      (a)    
  Interest. The outstanding principal balance of each credit subject hereto,
  and the amount of each drawing paid under the Standby Letter of Credit, shall
  bear interest from the date such credit is extended and/or drawing is paid,
  as applicable, to the date such amount is fully repaid by Borrower at the applicable
  rate of interest set forth in each promissory note or other instrument or document
  executed in connection therewith. 

      (b)    
  Computation
  and Payment. Interest shall be computed on the basis
  of a 360-day year, actual days elapsed. Interest shall be payable at the times
  and place set forth in each promissory note or other instrument or document
  required hereby. 

     
  (c)     Unused
  Commitment Fee. Borrower shall pay to Bank a fee equal
  to one-tenth percent (0.10%) per annum (computed on the basis of a 360-day year,
  actual days elapsed) on the average daily unused amount of the Loan Commitment,
  which fee shall be calculated on a monthly basis by Bank and shall be due and
  payable by Borrower in arrears within 30 days after each billing is sent by
  Bank.

     
  (d)     Letter
  of Credit Fees. Bank acknowledges that Borrower has
  previously paid to Bank an issuance fee in respect of the Standby Letter of
  Credit in an amount equal to one and one-half percent (1.50%) per annum (computed
  on the basis of a 360-day year, actual days elapsed) of the face amount thereof.
  Borrower shall pay to Bank fees upon the payment or negotiation of each drawing
  under the Standby Letter of Credit and fees upon the occurrence of any other
  activity with respect to the Standby Letter of Credit (including, without limitation,
  the

  of the Standby Letter of Credit) determined in accordance with Bank’s standard
  fees and charges then in effect for such activity. 

     
  (e)     Collection
  of Payments. Borrower authorizes Bank to collect all
  interest due under each credit subject hereto (including, without limitation,
  the Standby Letter of Credit) by charging Borrower’s deposit account number
  4091384644 with
  Bank for the full amount thereof. Should there be insufficient funds in any
  such deposit account to pay all such sums when due, the full amount of such
  deficiency shall be immediately due and payable by Borrower. 

      SECTION 1.5.     COLLATERAL.
  

      As security for all indebtedness
  of Borrower to Bank under the Loan Commitment and the Loan, Borrower hereby
  grants to Bank security interests of first priority in Borrower’s Wells Fargo
  Institutional Securities, LLC account number 12737300 (the “Securities Collateral”).

      Bank agrees to (i) release
  its security interest in the Securities Collateral to the extent that the same
  secures the Loan (but not to the extent that the Securities Collateral secures
  the Loan Commitment), and (ii) concurrently with such release, take a first
  priority lien in Borrower’s real property located at 300, 400, 500 and
  600 Wind River Way, Alameda, CA (the “Real Property Collateral”) as security
  for the Loan, in the event that all of the following conditions are satisfied:

       
    (i)      Borrower’s net income after taxes for the
    most recently ended four consecutive fiscal quarter period of Borrower (such
    period, the “Target Period”) shall be greater than $1.00, with net income
    after taxes greater than $1.00 for the last three consecutive fiscal quarters
    occurring in such Target Period; 

       
    (ii)     Borrower’s net income before taxes for the
    Target Period shall be equal to or greater than 85% of Borrower’s projected
    net income before taxes (based on Borrower’s projections as delivered
    to Bank on March 21, 2003, the “Projections”) for such Target Period; 

       
    (iii)    Borrower’s EBITDA for the Target Period shall
    be equal to or greater than 85% of Borrower’s projected EBITDA (based
    on the Projections and with “EBITDA” defined as net profit before tax plus
    interest expense (net of capitalized interest expense), depreciation expense
    and amortization expense) for such Target Period; 

       
    (iv)    the outstanding principal balance of the Loan at the
    end of the Target Period shall be equal to or less than 50% of the appraised
    value of the Real Property Collateral as determined by an appraisal ordered
    by and in form and content acceptable to Bank (the “Appraisal”); 

       
    (v)     the stabilized debt service coverage ratio of
    the Real Property Collateral (determined solely with respect to the Loan),
    as determined by the Appraisal, shall be equal to or greater than 1.25 to
    1.0 (assuming, solely for purposes of this calculation, that the Loan fully
    amortizes in 20 equal annual installments); 

       
    (vi)    Bank’s deed of trust (in form and content acceptable
    to Bank) shall have been recorded and Bank’s lien on the Real Property
    Collateral shall be insured pursuant to a title insurance policy in form and
    content acceptable to Bank and issued by an insurer acceptable to Bank (acting
    reasonably); and 

 -3-

  

       
    (vii)     Bank shall have received a Phase I environmental
    report covering the Real Property Collateral in form and content acceptable
    to Bank; and 

       
    (viii)    no Event of Default (or event or condition, which,
    with the passage of time or giving of notice, would constitute an Event of
    Default) shall then exist. 

 In the event that any Reinstatement
  Event (as defined below) occurs, Bank’s security interest in the Securities
  Collateral (to the extent that the same secured the Loan) shall automatically
  and without notice or further action be reinstated such that the Loan and Loan
  Commitment shall thereafter be secured by the Securities Collateral. 

 “Reinstatement Event”
  means any of the following: 

     
  (1)    Borrower shall cease to occupy all or substantially all
  of the Real Property Collateral. 

     
  (2)    A violation of either or both of the Tier 2 Financial
  Covenants (as defined in Section 4.9 hereof) shall have occurred. 

      Upon the reinstatement of
  Bank’s security interest in the Securities Collateral as described above
  and Borrower’s written confirmation to Bank of such reinstatement, Bank
  shall release its lien on the Real Property Collateral, and the violation(s)
  of the Tier 2 Financial Covenant(s) shall be deemed to have been waived (except
  if and to the extent that Liquidity was less than the $100,000,000.00 requirement
  set forth in Section 4.9(a) hereof). 

      All of the foregoing shall
  be evidenced by and subject to the terms of such security agreements, financing
  statements, deeds of trust and other documents as Bank shall reasonably require,
  all in form and substance satisfactory to Bank. Borrower shall reimburse Bank
  within five (5) business days after receipt of demand for all reasonable costs
  and expenses incurred by Bank in connection with any of the foregoing security,
  including without limitation, filing and recording fees and costs of appraisals,
  audits and title insurance.

  REPRESENTATIONS
  AND WARRANTIES 

      Borrower makes the following
  representations and warranties to Bank, which representations and warranties
  shall survive the execution of this Agreement and shall continue in full force
  and effect until the full and final payment, and satisfaction and discharge,
  of all obligations of Borrower to Bank subject to this Agreement. 

     
  SECTION 2.1.     LEGAL STATUS. Borrower is a corporation,
  duly organized and existing and in good standing under the laws of the State
  of Delaware, and is qualified or licensed to do business (and is in good standing
  as a foreign corporation, if applicable) in all jurisdictions in which such
  qualification or licensing is required or in which the failure to so qualify
  or to be so licensed would not reasonably be expected to have a Material Adverse
  Effect. For purposes of this Agreement, “Material Adverse Effect” shall mean
  any material adverse change in, or any material adverse effect on: (a) the operations,
  business, properties, liabilities or financial condition of Borrower; (b) the
  ability of Borrower to perform its payment obligations under the Loan Documents;
  and/or (c) the legality, validity, binding effect or enforceability of any Loan
  Document. For purposes hereof, “Obligations” means all obligations, indebtedness,
  and liabilities of Borrower of every kind and character owed to Bank, arising
  

 -4-

  
 directly or indirectly out
  of or in connection with the Loan Documents (other than the Standby Letter of
  Credit), including, without limitation, such obligations, indebtedness, and
  liabilities arising under successive transactions renewing, increasing, extending
  or continuing any of the foregoing, changing the interest rate or other terms
  thereof, or creating new or additional obligations, indebtedness, and liabilities
  after prior obligations, indebtedness, or liabilities have been in whole or
  in part satisfied, and further including, without limitation, all such obligations,
  indebtedness, and liabilities however arising, whether for principal, interest
  (including, without limitation, interest that, but for the filing of a petition
  under the federal Bankruptcy Reform Act, Title 11 of the United States Code,
  as amended or recodified from time to time (“Bankruptcy Code”) with respect
  to Borrower, would have accrued on any such obligations, indebtedness, or liabilities),
  letter of credit reimbursement obligations (other than in respect of the Standby
  Letter of Credit), fees, costs, expenses, premiums, charges, attorneys’ fees,
  or indemnity obligations, whether previously, now, or hereafter made, incurred
  or created, whether voluntarily or involuntarily, whether secured or unsecured
  (and if secured, regardless of the nature or extent of the security), whether
  or not now due, whether absolute or contingent, whether liquidated or unliquidated,
  whether determined or undetermined, whether Borrower may be liable individually
  or jointly with others, and whether made, incurred, or created before or after
  any entry of an order for relief with respect to Borrower in a case under the
  Bankruptcy Code. 

      SECTION 2.2.    
  AUTHORIZATION AND VALIDITY. This Agreement and each promissory note, contract,
  instrument and other document required hereby or at any time hereafter executed
  or authenticated by Borrower and delivered to Bank in connection herewith (collectively,
  the “Loan Documents”) have been duly authorized, and upon their execution and
  delivery in accordance with the provisions hereof will constitute legal, valid
  and binding agreements and obligations of Borrower or the party which executes
  the same, enforceable in accordance with their respective terms, except as the
  enforceability thereof may be limited by bankruptcy, insolvency or other similar
  laws of general application relating to or affecting the enforcement of creditors’
  rights or by general principles of equity.. 

      SECTION 2.3.     NO
  VIOLATION. The execution, delivery and performance by Borrower of each of the
  Loan Documents to which it is a party do not violate any provision of any law
  or regulation, or contravene any provision of the organizational documents of
  Borrower, or result in any breach of or default under any contract, obligation,
  indenture or other instrument to which Borrower is a party or by which Borrower
  may be bound. 

      SECTION 2.4.    
  LITIGATION. There are no pending, or to the best of Borrower’s knowledge threatened,
  actions, claims, investigations, suits or proceedings by or before any governmental
  authority, arbitrator, court or administrative agency which, if adversely determined,
  would reasonably be expected to have a Material Adverse Effect other than those
  disclosed by Borrower to Bank in writing prior to the date hereof. 

      SECTION 2.5.    
  CORRECTNESS OF FINANCIAL STATEMENT. The financial statement of Borrower dated
  October 31, 2002, a true copy of which has been delivered by Borrower to Bank
  prior to the date hereof, (a) is complete and correct and presents fairly the
  financial condition of Borrower on and as of such date, (b) discloses all liabilities
  of Borrower that are required to be reflected or reserved against on and as
  of such date under generally accepted accounting principles, whether liquidated
  or unliquidated, fixed or contingent, and (c) has been prepared in accordance
  with generally accepted accounting principles consistently applied. Since the
  date of such financial statement (i) no Material Adverse Effect has occurred
  and (ii) except for Permitted Liens, Borrower has not mortgaged, pledged, granted
  a security interest in or otherwise encumbered any of its assets or properties.
  

 -5- 

  
      SECTION 2.6.    
  INCOME TAX RETURNS. Borrower has no knowledge of any pending assessments or
  adjustments of its income tax payable with respect to any year other than any
  of the foregoing that would not reasonably be expected to have a Material Adverse
  Effect. 

      SECTION 2.7.    
  NO SUBORDINATION. There is no agreement, indenture, contract or instrument to
  which Borrower is a party or by which Borrower may be bound that requires the
  subordination in right of payment of any of Borrower’s obligations subject to
  this Agreement to any other obligation of Borrower. 

      SECTION 2.8.    
  PERMITS, FRANCHISES. Borrower possesses, and will hereafter possess, all permits,
  consents, approvals, franchises and licenses required and rights to all trademarks,
  trade names, patents, and fictitious names, if any, necessary to enable it to
  conduct the business in which it is now engaged in compliance with applicable
  law except any, the failure of which to possess would not reasonably be expected
  to have a Material Adverse Effect.

      SECTION 2.9.    
  ERISA. Borrower is in compliance in all material respects with all applicable
  provisions of the Employee Retirement Income Security Act of 1974, as amended
  or recodified from time to time (“ERISA”); Borrower has not violated any provision
  of any defined employee pension benefit plan (as defined in ERISA) maintained
  or contributed to by Borrower (each, a “Plan”) except for any violation which
  would not reasonably be expected to have a Material Adverse Effect; no Reportable
  Event as defined in ERISA has occurred and is continuing unwaived with respect
  to any Plan initiated by Borrower; Borrower has met its minimum funding requirements
  under ERISA with respect to each Plan; and each Plan will be able to fulfill
  its benefit obligations as they come due in accordance with the Plan documents
  and under generally accepted accounting principles. 

      SECTION 2.10.     OTHER
  OBLIGATIONS. Borrower is not in default on any obligation for borrowed money
  or any material purchase money obligation and is not in default under any other
  lease, commitment, contract, instrument or obligation other than any default
  that would not reasonably be expected to have a Material Adverse Effect. 

      SECTION 2.11.    
  ENVIRONMENTAL MATTERS. Except as disclosed by Borrower to Bank in writing prior
  to the date hereof, Borrower is in compliance in all respects with all applicable
  federal or state environmental, hazardous waste, health and safety statutes,
  and any rules or regulations adopted pursuant thereto, which govern or affect
  any of Borrower’s operations and/or properties, including without limitation,
  the Comprehensive Environmental Response, Compensation and Liability Act of
  1980, the Superfund Amendments and Reauthorization Act of 1986, the Federal
  Resource Conservation and Recovery Act of 1976, and the Federal Toxic Substances
  Control Act, as any of the same may be amended, modified or supplemented from
  time to time, except for any non-compliance that would not reasonably be expected
  to have a Material Adverse Effect. None of the operations of Borrower is the
  subject of any federal or state investigation evaluating whether any remedial
  action involving a material expenditure is needed to respond to a release of
  any toxic or hazardous waste or substance into the environment, except for any
  such investigation or expenditure that would not reasonably be expected to have
  a Material Adverse Effect. Borrower has no contingent liability in connection
  with any release of any toxic or hazardous waste or substance into the environment,
  except for liabilities that would not reasonably be expected to have a Material
  Adverse Effect.

 Credit Agreement-Final -15-

  
     
  (b)     Governing
  Rules. Any arbitration proceeding will (i) proceed in
  a location in California selected by the American Arbitration Association (“AAA”);
  (ii) be governed by the Federal Arbitration Act (Title 9 of the United States
  Code), notwithstanding any conflicting choice of law provision in any of the
  documents between the parties; and (iii) be conducted by the AAA, or such other
  administrator as the parties shall mutually agree upon, in accordance with the
  AAA’s commercial dispute resolution procedures, unless the claim or counterclaim
  is at least $1,000,000.00 exclusive of claimed interest, arbitration fees and
  costs in which case the arbitration shall be conducted in accordance with the
  AAA’s optional procedures for large, complex commercial disputes (the commercial
  dispute resolution procedures or the optional procedures for large, complex
  commercial disputes to be referred to, as applicable, as the “Rules”). If there
  is any inconsistency between the terms hereof and the Rules, the terms and procedures
  set forth herein shall control. Any party who fails or refuses to submit to
  arbitration following a demand by any other party shall bear all costs and expenses
  incurred by such other party in compelling arbitration of any dispute. Nothing
  contained herein shall be deemed to be a waiver by any party that is a bank
  of the protections afforded to it under 12 U.S.C. §9191 or any similar
  applicable state law. 

     
  (c)     No
  Waiver of Provisional Remedies, Self-Help and Foreclosure.
  The arbitration requirement does not limit the right of any party to (i) foreclose
  against real or personal property collateral; (ii) exercise self-help remedies
  relating to collateral or proceeds of collateral such as setoff or repossession;
  or (iii) obtain provisional or ancillary remedies such as replevin, injunctive
  relief, attachment or the appointment of a receiver, before during or after
  the pendency of any arbitration proceeding. This exclusion does not constitute
  a waiver of the right or obligation of any party to submit any dispute to arbitration
  or reference hereunder, including those arising from the exercise of the actions
  detailed in sections (i), (ii) and (iii) of this paragraph. 

     (d)     Arbitrator
  Qualifications and Powers . Any
  arbitration proceeding in which the amount
  in controversy is $5,000,000.00 or less will be decided by a single arbitrator
  selected according to the Rules, and who shall not render an award of greater
  than $5,000,000.00. Any dispute in which the amount in controversy exceeds $5,000,000.00
  shall be decided by majority vote of a panel of three arbitrators; provided
  that all three arbitrators must actively participate in all hearings and deliberations.
  The arbitrator will be a neutral attorney licensed in the State of California
  or a neutral retired judge of the state or federal judiciary of California,
  in either case with a minimum of ten years experience in the substantive law
  applicable to the subject matter of the dispute to be arbitrated. The arbitrator
  will determine whether or not an issue is arbitratable and will give effect
  to the statutes of limitation in determining any claim. In any arbitration proceeding
  the arbitrator will decide (by documents only or with a hearing at the arbitrator’s
  discretion) any pre-hearing motions which are similar to motions to dismiss
  for failure to state a claim or motions for summary adjudication. The arbitrator
  shall resolve all disputes in accordance with the substantive law of California
  and may grant any remedy or relief that a court of such state could order or
  grant within the scope hereof and such ancillary relief as is necessary to make
  effective any award. The arbitrator shall also have the power to award recovery
  of all costs and fees, to impose sanctions and to take such other action as
  the arbitrator deems necessary to the same extent a judge could pursuant to
  the Federal Rules of Civil Procedure, the California Rules of Civil Procedure
  or other applicable law. Judgment upon the award rendered by the arbitrator
  may be entered in any court having jurisdiction. The institution and maintenance
  of an action for judicial relief or pursuit of a provisional or ancillary remedy
  shall not constitute a waiver of the right of any party, including the plaintiff,
  to submit the controversy or claim to arbitration if any other party contests
  such action for judicial relief. 

 -16-

  
     
  (e)     Discovery.
  In any arbitration proceeding discovery will be permitted in accordance with
  the Rules. All discovery shall be expressly limited to matters directly relevant
  to the dispute being arbitrated and must be completed no later than 20 days
  before the hearing date and within 180 days of the filing of the dispute with
  the AAA. Any requests for an extension of the discovery periods, or any discovery
  disputes, will be subject to final determination by the arbitrator upon a showing
  that the request for discovery is essential for the party’s presentation and
  that no alternative means for obtaining information is available. 

      (f)    
  Class Proceedings
  and Consolidations. The resolution of any dispute arising
  pursuant to the terms of this Agreement shall be determined by a separate arbitration
  proceeding and such dispute shall not be consolidated with other disputes or
  included in any class proceeding. 

     (g)    
  Payment Of Arbitration
  Costs And Fees. The arbitrator shall award all
  costs and expenses
  of the arbitration proceeding.

     (h)    
  Real Property Collateral;
  Judicial Reference. Notwithstanding
  anything herein to the contrary,
  no dispute shall be submitted to arbitration if the dispute concerns indebtedness
  secured directly or indirectly, in whole or in part, by any real property unless
  (i) the holder of the mortgage, lien or security interest specifically elects
  in writing to proceed with the arbitration, or (ii) all parties to the arbitration
  waive any rights or benefits that might accrue to them by virtue of the single
  action rule statute of California, thereby agreeing that all indebtedness and
  obligations of the parties, and all mortgages, liens and security interests
  securing such indebtedness and obligations, shall remain fully valid and enforceable.
  If any such dispute is not submitted to arbitration, the dispute shall be referred
  to a referee in accordance with California Code of Civil Procedure Section 638
  et seq., and this general reference agreement is intended to be specifically
  enforceable in accordance with said Section 638. A referee with the qualifications
  required herein for arbitrators shall be selected pursuant to the AAA’s
  selection procedures. Judgment upon the decision rendered by a referee shall
  be entered in the court in which such proceeding was commenced in accordance
  with California Code of Civil Procedure Sections 644 and 645. 

      (i)    
  Miscellaneous.
  To the maximum extent practicable, the AAA, the arbitrators and the parties
  shall take all action required to conclude any arbitration proceeding within
  180 days of the filing of the dispute with the AAA. No arbitrator or other party
  to an arbitration proceeding may disclose the existence, content or results
  thereof, except for disclosures of information by a party required in the ordinary
  course of its business or by applicable law or regulation. If more than one
  agreement for arbitration by or between the parties potentially applies to a
  dispute, the arbitration provision most directly related to the Loan Documents
  or the subject matter of the dispute shall control. This arbitration provision
  shall survive termination, amendment or expiration of any of the Loan Documents
  or any relationship between the parties.

 FORM OF LOAN
  COMMITMENT NOTE

	$37,400,000.00	 Oakland,
      California

      April 15, 2003 

      FOR VALUE RECEIVED, the
  undersigned WIND RIVER SYSTEMS, INC., a Delaware corporation (“Borrower”), promises
  to pay to the order of WELLS FARGO BANK, NATIONAL ASSOCIATION (“Bank”) at its
  office at One Kaiser Plaza, Suite 850, Oakland, California, or at such other
  place as the holder hereof may designate, in lawful money of the United States
  of America and in immediately available funds, the principal sum of Thirty-Seven
  Million Four Hundred Thousand Dollars ($37,400,000.00), or so much thereof as
  may be advanced and be outstanding, with interest thereon, to be computed on
  each advance from the date of its disbursement as set forth herein. 

 DEFINITIONS: 

      As used herein, the following
  terms shall have the meanings set forth after each, and any other term defined
  in this Note shall have the meaning set forth at the place defined; provided
  that any capitalized term used but not otherwise defined herein shall have the
  meaning set forth in that certain Credit Agreement, dated as of April 15, 2003
  (as amended, supplemented and/or otherwise modified from time to time, the “Credit
  Agreement”), between Bank and Borrower): 

     “Business Day”
  means any day except a Saturday, Sunday or any other day on which commercial
  banks in California are authorized or required by law to close. 

     
  “Fixed Rate
  Term” means a period commencing on a Business Day and
  continuing for 1, 2, 3, 6, 9 or 12 months, as designated by Borrower, during
  which all or a portion of the outstanding principal balance of this Note bears
  interest determined in relation to LIBOR; provided that no Fixed Rate
  Term may be selected for a principal amount less than $100,000.00
  or an integral multiple thereof;
  provided
  further that
  no Fixed Rate Term shall extend beyond the scheduled
  maturity date hereof. If any Fixed Rate Term would end on a day which is not
  a Business Day, then such Fixed Rate Term shall be extended to the next succeeding
  Business Day. 

     
  “LIBOR”
  means the rate per annum and determined pursuant to the following formula:

	 	 Base
      LIBOR  
	LIBOR = 	

	 	 100%
      - LIBOR Reserve Percentage 

        (i)    
    “Base LIBOR” means the rate per annum for United States dollar deposits
    quoted by Bank as the Inter-Bank Market Offered Rate, with the understanding
    that such rate is quoted by Bank for the purpose of calculating effective
    rates of interest for loans making reference thereto, on the first day of
    a Fixed Rate Term for delivery of funds on said date for a period of time
    approximately equal to the number of days in such Fixed Rate Term and in an
    amount approximately equal to the principal amount to which such Fixed Rate
    Term applies. Borrower understands and agrees that Bank may base its quotation
    of the Inter-Bank Market Offered Rate upon such offers or other market indicators
    of the Inter-Bank Market as Bank in its discretion deems appropriate including,

 A-1

  

   but not limited to, the
    rate offered for U.S. dollar deposits on the London Inter-Bank Market. 

        (ii)    
    “LIBOR Reserve Percentage” means the reserve percentage prescribed
    by the Board of Governors of the Federal Reserve System (or any successor)
    for “Eurocurrency Liabilities” (as defined in Regulation D of the Federal
    Reserve Board, as amended), adjusted by Bank for expected changes in such
    reserve percentage during the applicable Fixed Rate Term. 

     “Note”
  means this Loan Commitment Note as amended, supplemented and/or otherwise modified
  from time to time in accordance with the provisions hereof and of the Credit
  Agreement.

     “Prime Rate”
  means at any time the rate of interest most recently announced within Bank at
  its principal office as its Prime Rate, with the understanding that the Prime
  Rate is one of Bank’s base rates and serves as the basis upon which effective
  rates of interest are calculated for those loans making reference thereto, and
  is evidenced by the recording thereof after its announcement in such internal
  publication or publications as Bank may designate. 

 INTEREST: 

     
  (a)     Interest.
  The outstanding principal balance of this Note shall bear interest (computed
  on the basis of a 360-day year, actual days elapsed) either (i) at a fluctuating
  rate per annum equal to the Prime Rate in effect from time to time, or (ii)
  at a fixed rate per annum determined by Bank to be four-tenths of one percent
  (0.40%) above LIBOR in effect on the first day of the applicable Fixed Rate
  Term. When any interest, fee or charge payable hereunder is determined in relation
  to the Prime Rate, each change in the rate of interest hereunder shall become
  effective on the date each Prime Rate change is announced within Bank. With
  respect to each LIBOR selection hereunder, Bank is hereby authorized to note
  the date, principal amount, interest rate and Fixed Rate Term applicable thereto
  and any payments made thereon on Bank’s books and records (either manually or
  by electronic entry) and/or on any schedule attached to this Note, which notations
  shall be prima facie evidence of the accuracy of the information noted; provided
  that any failure by Bank to make any such notation shall not affect Borrower’s
  liability in respect of the amounts outstanding hereunder. 

     (b)    
  Selection of Interest
  Rate Options. At any time any portion of this Note bears
  interest determined in relation
  to LIBOR, it may be continued by Borrower at the end of the Fixed Rate Term
  applicable thereto so that all or a portion thereof bears interest determined
  in relation to the Prime Rate or to LIBOR for a new Fixed Rate Term designated
  by Borrower. At any time any portion of this Note bears interest determined
  in relation to the Prime Rate, Borrower may convert all or a portion thereof
  so that it bears interest determined in relation to LIBOR for a Fixed Rate Term
  designated by Borrower. At such time as Borrower requests an advance hereunder
  or wishes to select a LIBOR option for all or a portion of the outstanding principal
  balance hereof, and at the end of each Fixed Rate Term, Borrower shall give
  Bank notice specifying: (i) the interest rate option selected by Borrower; (ii)
  the principal amount subject thereto; and (iii) for each LIBOR selection, the
  length of the applicable Fixed Rate Term. Any such notice may be given by telephone
  (or such other electronic method as Bank may permit) so long as, with respect
  to each LIBOR selection, (A) if requested by Bank, Borrower provides to Bank
  written confirmation thereof not later than three (3) Business Days after such
  notice is given, and (B) such notice is given to Bank prior to 10:00 a.m. on
  the first day of the Fixed Rate Term, or at a later time during any Business
  Day if Bank, at it’s sole option but 

 A-2

  
 without obligation to do
  so, accepts Borrower’s notice and quotes a fixed rate to Borrower. If Borrower
  does not immediately accept a fixed rate when quoted by Bank, the quoted rate
  shall expire and any subsequent LIBOR request from Borrower shall be subject
  to a redetermination by Bank of the applicable fixed rate. If no specific designation
  of interest is made at the time any advance is requested hereunder or at the
  end of any Fixed Rate Term, Borrower shall be deemed to have made a LIBOR interest
  selection for such advance or the principal amount to which such Fixed Rate
  Term applied for a Fixed Rate Term of one month. 

      (c)    
  Taxes and Regulatory
  Costs. Borrower shall pay to Bank immediately upon demand
  (provided that such demand is made within 180 days of Bank becoming aware of
  any additional amounts referred to in the following clauses (i) and (ii) of
  this Section (c) and in any event not more than 180 days after all amounts otherwise
  payable hereunder have been paid in full), in addition to any other amounts
  due or to become due hereunder, any and all (i) withholdings, interest equalization
  taxes, stamp taxes or other taxes (except income and franchise taxes) imposed
  by any domestic or foreign governmental authority and related in any manner
  to LIBOR, and (ii) future, supplemental, emergency or other changes in the LIBOR
  Reserve Percentage, assessment rates imposed by the Federal Deposit Insurance
  Corporation, or similar requirements or costs imposed by any domestic or foreign
  governmental authority or resulting from compliance by Bank with any request
  or directive (whether or not having the force of law) from any central bank
  or other governmental authority after the date hereof and related in any manner
  to LIBOR to the extent they are not included in the calculation of LIBOR. In
  determining which of the foregoing are attributable to any LIBOR option available
  to Borrower hereunder, any reasonable allocation made by Bank among its operations
  shall be conclusive and binding upon Borrower. 

      If Borrower is required
  to pay any amount to Bank pursuant to this Section (c), then Bank shall use
  reasonable efforts (consistent with legal and regulatory restrictions) to change
  the jurisdiction of its lending office respecting LIBOR advances so as to eliminate
  any such additional payment by Borrower which may thereafter accrue, if such
  change in the sole and absolute judgment of Bank (acting in good faith) is not
  otherwise disadvantageous to Bank. 

      If Borrower pays any additional
  amount under this Section (c) to Bank and Bank determines it is sole discretion
  acting in good faith that it has actually received or realized in connection
  therewith any refund or any reduction of, or credit against, its tax liabilities
  in or with respect to the taxable year in which the additional amount is paid
  (a “Tax Benefit”), Bank shall pay to Borrower such amount that Bank
  shall, in its sole discretion acting in good faith, determine is equal to the
  net benefit, after tax, which was obtained by Bank in such year as a consequence
  of such Tax Benefit; provided
  that (A) Bank may determine, acting in good faith, in its sole discretion consistent
  with the policies of Bank, whether to seek a Tax Benefit; and (B) nothing in
  this Section (c) shall require Bank to disclose any confidential information
  to Borrower (including, without limitation, its tax returns). 

      (d)    
  Payment of
  Interest. Interest accrued on this Note shall be payable
  monthly, in arrears, on the fifteenth day of each month, commencing May 15,
  2003, and on the maturity date of this Note; provided that if any such
  interest due date is not a Business Day, then such payment shall be due on the
  next succeeding Business Day. 

      (e)    
  Default Interest.
  From and after the occurrence of an Event of Default and during the continuation
  thereof so long as the same shall remain unwaived, the outstanding principal
  balance of this Note shall bear interest until paid in full at an increased
  rate per annum (computed on the basis of a 360-day year, actual days elapsed)
  equal to three percent (3.00%) above the rate of interest from time to time
  otherwise applicable to this Note. 

 A-3 

  
 BORROWINGS; REPAYMENTS; PREPAYMENTS;
  APPLICATION OF PAYMENTS: 

      (a)    
  Borrowing and
  Repayment. Borrower may from time to time during the
  term of this Note borrow and partially or wholly repay its outstanding borrowings,
  subject to all of the limitations, terms and conditions of this Note and of
  any document executed in connection with or governing this Note; provided
  that amounts repaid or prepaid may not be reborrowed; provided further
  that the outstanding amount of all advances made to Borrower under this Note
  shall not at any time exceed the principal amount stated above. Each advance
  requested by Borrower hereunder shall be in a minimum principal amount equal
  to $100,000.00 or an integral multiple thereof. The unpaid principal balance
  of this Note at any time shall be the total amounts advanced hereunder by the
  holder hereof less the amount of principal payments made hereon by or for Borrower,
  which balance may be endorsed hereon from time to time by the holder. The outstanding
  principal balance of this Note (together with all amounts outstanding hereunder
  or in respect hereof) shall be due and payable in full on April 15, 2005.

      (b)    
  Advances.
  Advances hereunder, to the total amount of the principal sum stated above, may
  be made by the holder at the oral or written request of (i) Dianne DaRosa-White
  or Tyler Painter, any one acting alone, who are authorized to request advances
  and direct the disposition of any advances until written notice of the revocation
  of such authority is received by the holder at the office designated above,
  or (ii) any Person, with respect to advances deposited to the credit of any
  deposit account of Borrower, which advances, when so deposited, shall be conclusively
  presumed to have been made to or for the benefit of Borrower regardless of the
  fact that persons other than those authorized to request advances may have authority
  to draw against such account. The holder shall have no obligation to determine
  whether any person requesting an advance is or has been authorized by Borrower.
  

     (c)    
  Prepayments.

             
  (i)     Prime
  Rate. Borrower may on one (1) Business Day prior written
  notice to Bank, prepay principal on any portion of this Note that bears interest
  determined in relation to the Prime Rate at any time, in any amount and without
  penalty, together with accrued interest on the amount being prepaid. 

            
  (ii)     LIBOR.
  Borrower may, on three (3) Business Days prior written notice to Bank, prepay
  principal on any portion of this Note which bears interest determined in relation
  to LIBOR at any time and in the minimum amount of $100,000.00 or an integral
  multiple thereof, together with accrued interest on the amount being prepaid;
  provided that, if the outstanding principal balance of such portion of
  this Note is less than such amount, the minimum prepayment amount shall be the
  entire outstanding principal balance thereof; provided further
  that, in consideration of Bank providing Borrower with the ability to repay
  or prepay any portion of an advance that bears interest determined in relation
  to LIBOR on any day other than the last day of the Fixed Rate Term therefor
  (whether an optional prepayment, a mandatory prepayment, a payment upon acceleration
  or otherwise), Borrower shall pay to Bank promptly upon demand a fee which is
  the sum of the discounted monthly differences for each month from the month
  of prepayment through the month in which such Fixed Rate Term matures, calculated
  as follows for each such month: 

       
    (i)     Determine the amount of interest which would have
    accrued each month on the amount prepaid at the interest rate applicable to
    such amount had it remained outstanding until the last day of the Fixed Rate
    Term applicable thereto. 

 A-4

  

        (ii)     Subtract
    from the amount determined in (i) above the amount of interest which would
    have accrued for the same month on the amount prepaid for the remaining term
    of such Fixed Rate Term at LIBOR in effect on the date of prepayment for new
    loans made for such term and in a principal amount equal to the amount prepaid.
    

        (iii)    
    If the result obtained in (ii) for any month is greater than zero, discount
    that difference by LIBOR used in (ii) above. 

 Borrower acknowledges that
  prepayment of such amount may result in Bank incurring additional costs, expenses
  and/or liabilities, and that it is difficult to ascertain the full extent of
  such costs, expenses and/or liabilities. Borrower, therefore, agrees to pay
  the above-described prepayment fee and agrees that such amount represents a
  reasonable estimate of the prepayment costs, expenses and/or liabilities of
  Bank. If Borrower fails to pay such amount when due, such amount shall thereafter
  bear interest until paid at a rate per annum three percent (3.00%) above the
  Prime Rate in effect from time to time (computed on the basis of a 360-day year,
  actual days elapsed). 

      (d)    
  Application
  of Payments. Each payment (including, without limitation,
  prepayments) made on this Note shall be credited first, to any fees, costs or
  expenses due and payable and outstanding under the Loan Documents, second, to
  interest then due and third, to the outstanding principal balance hereof. All
  payments credited to principal shall be applied first, to the outstanding principal
  balance of this Note which bears interest determined in relation to the Prime
  Rate, if any, and second, to the outstanding principal balance of this Note
  which bears interest determined in relation to LIBOR, with such payments applied
  to the oldest Fixed Rate Term first. 

 PERMANENT REDUCTIONS OR TERMINATION
  OF THE UNUSED LOAN COMMITMENT: 

      Borrower may, at any time,
  by notice to Bank (which notice, once given, shall be irrevocable), permanently
  reduce or terminate the unused portion of the Loan Commitment either in whole
  or in part; provided that each partial reduction shall be in
  an aggregate amount of not less than $100,000.00 or an integral multiple thereof.
  

 EVENTS OF DEFAULT: 

      This Note is made pursuant
  to and is subject to the terms and conditions of the Credit Agreement. Any Event
  of Default (as that term is defined in the Credit Agreement) shall constitute
  an “Event of Default” hereunder. 

 GENERAL PROVISIONS: 

       (a)    
  Successors, Assignment. This Note shall be binding upon and inure to
  the benefit of the heirs, executors, administrators, legal representatives,
  successors and assigns of Borrower and the holder hereof; provided that
  Borrower may not assign or transfer its interest hereunder without the express
  prior written consent of the holder hereof.

      (b)    
  Entire Agreement;
  Amendment. This Note and the other Loan Documents constitute
  the entire agreement between Borrower and Bank with respect to each credit subject
  hereto and supersede all prior negotiations, communications, discussions and
  correspondence

  hereof. This Note may be amended or modified only in writing signed by Borrower
  and the holder hereof.

      California

      April 15, 2003 

      FOR VALUE RECEIVED, the
  undersigned WIND RIVER SYSTEMS, INC., a Delaware corporation (“Borrower”), promises
  to pay to the order of WELLS FARGO BANK, NATIONAL ASSOCIATION (“Bank”) at its

  or 12 months, as designated by Borrower, during which all or a portion of the
  outstanding principal balance of this Note bears interest determined in relation
  to LIBOR; provided that no Fixed Rate Term may be selected for a principal
  amount less than $100,000.00 or an integral multiple thereof; provided
  further that no Fixed Rate Term shall extend beyond the scheduled maturity

      “LIBOR”
  means the rate per annum and determined pursuant to the following formula: 

	 	 Base
      LIBOR  
	LIBOR =

        (i)    
    “Base LIBOR” means the rate per annum for United States dollar deposits
    quoted by Bank as the Inter-Bank Market Offered Rate, with the understanding
    that such rate is quoted by Bank for the purpose of calculating effective
    rates of interest for loans making reference thereto, on the first day of
    a Fixed Rate Term for delivery of funds on said date for a period of time
    approximately equal to the number of days in such Fixed Rate Term and in an
    amount approximately equal to the principal amount to which such Fixed Rate
    Term applies. Borrower understands and agrees that Bank may base its quotation
    of the Inter-Bank Market Offered Rate upon such offers or other market indicators
    of the Inter-Bank Market as Bank in its discretion deems appropriate including,

 B-1-

    rate offered for U.S. dollar deposits on the London Inter-Bank Market.

  time to time in accordance with the provisions hereof and of the Credit Agreement.

     “Prime Rate”
  means at any time the rate of interest most recently announced within Bank at

  is evidenced by the recording thereof after its announcement in such internal
  publication or publications as Bank may designate. 

 INTEREST: 

     
  (a)     Interest.
  The outstanding principal balance of this Note shall bear interest (computed
  on the basis of a 360-day year, actual days elapsed) either (i) at a fluctuating
  rate per annum equal to the Prime Rate in effect from time to time, or (ii)
  (A) so long as the Securities Collateral secures this Note, four-tenths percent
  (0.4%) above LIBOR in effect on the first day of each Fixed Rate Term, or (B)
  so long as the Securities Collateral does not secure this Note, one and one
  quarter percent (1.25%) above LIBOR in effect on the first day of each Fixed
  Rate Term. When any interest, fee or charge payable hereunder is determined
  in relation to the Prime Rate, each change in the rate of interest hereunder
  shall become effective on the date each Prime Rate change is announced within
  Bank. With respect to each LIBOR selection hereunder, Bank is hereby authorized
  to note the date, principal amount, interest rate and Fixed Rate Term applicable
  thereto and any payments made thereon on Bank’s books and records (either
  manually or by electronic entry) and/or on any schedule attached to this Note,
  which notations shall be prima facie evidence of the accuracy of the information
  noted; provided that any failure by Bank to make any such notation shall
  not affect Borrower’s liability in respect of the amounts outstanding hereunder.
  

     (b)
       Selection
  of Interest Rate Options. At any time any portion of
  this Note bears interest
  determined in relation to LIBOR, it may be continued by Borrower at the end
  of the Fixed Rate Term applicable thereto so that all or a portion thereof bears
  interest determined in relation to the Prime Rate or to LIBOR for a new Fixed
  Rate Term designated by Borrower. At any time any portion of this Note bears
  interest determined in relation to the Prime Rate, Borrower may convert all
  or a portion thereof so that it bears interest determined in relation to LIBOR
  for a Fixed Rate Term designated by Borrower. At such time as Borrower requests
  an advance hereunder or wishes to select a LIBOR option for all or a portion
  of the outstanding principal balance hereof, and at the end of each Fixed Rate
  Term, Borrower shall give Bank notice specifying: (i) the interest rate option
  selected by Borrower; (ii) the principal amount subject thereto; and (iii) for
  each LIBOR selection, the length of the applicable Fixed Rate Term. Any such
  notice may be given by telephone (or such other electronic method as Bank may
  permit) so long as, with respect to each LIBOR selection, (A) if requested by
  Bank, Borrower provides to Bank written confirmation thereof not later than
  three (3) Business Days after such notice is given, and (B) such notice is given
  to Bank prior to 10:00 a.m. on the first day of the 

 B-2-

  
 Fixed Rate Term, or at a
  later time during any Business Day if Bank, at it’s sole option but without
  obligation to do so, accepts Borrower’s notice and quotes a fixed rate to Borrower.
  If Borrower does not immediately accept a fixed rate when quoted by Bank, the
  quoted rate shall expire and any subsequent LIBOR request from Borrower shall
  be subject to a redetermination by Bank of the applicable fixed rate. If no
  specific designation of interest is made at the time any advance is requested
  hereunder or at the end of any Fixed Rate Term, Borrower shall be deemed to
  have made a LIBOR interest selection for such advance or the principal amount
  to which such Fixed Rate Term applied for a Fixed Rate Term of one month. 

      (c)    
  Taxes and Regulatory
  Costs. Borrower shall pay to Bank immediately upon demand
  (provided that such demand is made within 180 days of Bank becoming aware of
  any additional amounts referred to in the following clauses (i) and (ii) of
  this Section (c) and in any event not more than 180 days after all amounts otherwise
  payable hereunder have been paid in full), in addition to any other amounts
  due or to become due hereunder, any and all (i) withholdings, interest equalization
  taxes, stamp taxes or other taxes (except income and franchise taxes) imposed
  by any domestic or foreign governmental authority and related in any manner
  to LIBOR, and (ii) future, supplemental, emergency or other changes in the LIBOR
  Reserve Percentage, assessment rates imposed by the Federal Deposit Insurance
  Corporation, or similar requirements or costs imposed by any domestic or foreign
  governmental authority or resulting from compliance by Bank with any request
  or directive (whether or not having the force of law) from any central bank
  or other governmental authority after the date hereof and related in any manner
  to LIBOR to the extent they are not included in the calculation of LIBOR. In
  determining which of the foregoing are attributable to any LIBOR option available
  to Borrower hereunder, any reasonable allocation made by Bank among its operations
  shall be conclusive and binding upon Borrower. 

      If Borrower is required
  to pay any amount to Bank pursuant to this Section (c), then Bank shall use
  reasonable efforts (consistent with legal and regulatory restrictions) to change
  the jurisdiction of its lending office respecting LIBOR advances so as to eliminate
  any such additional payment by Borrower which may thereafter accrue, if such
  change in the sole and absolute judgment of Bank (acting in good faith) is not
  otherwise disadvantageous to Bank. 

      If Borrower pays any additional
  amount under this Section (c) to Bank and Bank determines it is sole discretion
  acting in good faith that it has actually received or realized in connection
  therewith any refund or any reduction of, or credit against, its tax liabilities
  in or with respect to the taxable year in which the additional amount is paid
  (a “Tax Benefit”), Bank shall pay to Borrower such amount that Bank
  shall, in its sole discretion acting in good faith, determine is equal to the
  net benefit, after tax, which was obtained by Bank in such year as a consequence
  of such Tax Benefit; provided
  that (A) Bank may determine, acting in good faith, in its sole discretion consistent
  with the policies of Bank, whether to seek a Tax Benefit; and (B) nothing in
  this Section (c) shall require Bank to disclose any confidential information
  to Borrower (including, without limitation, its tax returns). 

     
  (d)     Payment
  of Interest. Interest accrued on this Note shall be
  payable monthly, in arrears, on the fifteenth day of each month, commencing
  May 15, 2003, and on the maturity date of this Note; provided that if
  any such interest due date is not a Business Day, then such payment shall be
  due on the next succeeding Business Day. 

      (e)    
  Default Interest.
  From and after the occurrence of an Event of Default and during the continuation
  thereof so long as the same shall remain unwaived, the outstanding principal
  balance of this Note shall bear interest until paid in full at an increased
  rate per annum 

 B-3-

  
 (computed on the basis of
  a 360-day year, actual days elapsed) equal to three percent (3.00%) above the
  rate of interest from time to time otherwise applicable to this Note. 

 BORROWINGS; REPAYMENTS; PREPAYMENTS;
  APPLICATION OF PAYMENTS: 

      (a)    
  Borrowing and
  Repayment. Borrower may not reborrow any amounts paid
  or prepaid hereunder. Each advance requested by Borrower hereunder shall be
  in a minimum principal amount equal to $100,000.00 or any integral multiple
  thereof. No advances may be obtained hereunder following the earlier to occur
  of (i) the date of the initial extension of credit under the Credit Agreement
  and (ii) May 15, 2003. The unpaid principal balance of this Note at any time
  shall be the total amounts advanced hereunder by the holder hereof less the
  amount of principal payments made hereon by or for Borrower, which balance may
  be endorsed hereon from time to time by the holder. The outstanding principal
  balance of this Note (together with all amounts outstanding hereunder or in
  respect hereof) shall be due and payable in full on April 15, 2005.

      (b)    
  Advances.
  Advances hereunder, to the total amount of the principal sum stated above, may
  be made by the holder at the oral or written request of (i) Dianne DaRosa-White
  or Tyler Painter, any one acting alone, who are authorized to request advances
  and direct the disposition of any advances until written notice of the revocation
  of such authority is received by the holder at the office designated above,
  or (ii) any Person, with respect to advances deposited to the credit of any
  deposit account of Borrower, which advances, when so deposited, shall be conclusively
  presumed to have been made to or for the benefit of Borrower regardless of the
  fact that persons other than those authorized to request advances may have authority
  to draw against such account. The holder shall have no obligation to determine
  whether any person requesting an advance is or has been authorized by Borrower.
  

      (c)    
  Prepayments.
  

             
  (i)     Prime
  Rate. Borrower may, on one (1) Business Day prior written
  notice to Bank, prepay principal on any portion of this Note that bears interest
  determined in relation to the Prime Rate at any time, in any amount and without
  penalty, together with accrued interest on the amount being prepaid. 

             
  (ii)     LIBOR.
  Borrower may, on three (3) Business Days prior written notice to Bank, prepay
  principal on any portion of this Note which bears interest determined in relation
  to LIBOR at any time and in the minimum amount of $100,000.00 or an integral
  multiple thereof, together with accrued interest on the amount being prepaid;
  provided that, if the outstanding principal balance of such portion of
  this Note is less than such amount, the minimum prepayment amount shall be the
  entire outstanding principal balance thereof; provided further
  that, in consideration of Bank providing Borrower with the ability to repay
  or prepay any portion of an advance that bears interest determined in relation
  to LIBOR on any day other than the last day of the Fixed Rate Term therefor
  (whether an optional prepayment, a mandatory prepayment, a payment upon acceleration
  or otherwise), Borrower shall pay to Bank promptly upon demand a fee which is
  the sum of the discounted monthly differences for each month from the month
  of prepayment through the month in which such Fixed Rate Term matures, calculated
  as follows for each such month: 

       
    (i)     Determine the amount of interest which would have
    accrued each month on the amount prepaid at the interest rate applicable to
    such amount had it remained outstanding until the last day of the Fixed Rate
    Term applicable thereto. 

 B-4-

  

        (ii)     Subtract
    from the amount determined in (i) above the amount of interest which would
    have accrued for the same month on the amount prepaid for the remaining term
    of such Fixed Rate Term at LIBOR in effect on the date of prepayment for new
    loans made for such term and in a principal amount equal to the amount prepaid.
    

        (iii)     If
    the result obtained in (ii) for any month is greater than zero, discount that
    difference by LIBOR used in (ii) above. 

 Borrower acknowledges that
  prepayment of such amount may result in Bank incurring additional costs, expenses
  and/or liabilities, and that it is difficult to ascertain the full extent of
  such costs, expenses and/or liabilities. Borrower, therefore, agrees to pay
  the above-described prepayment fee and agrees that such amount represents a
  reasonable estimate of the prepayment costs, expenses and/or liabilities of
  Bank. If Borrower fails to pay such amount when due, such amount shall thereafter
  bear interest until paid at a rate per annum three percent (3.00%) above the
  Prime Rate in effect from time to time (computed on the basis of a 360-day year,
  actual days elapsed). 

     
  (d)   Application
  of Payments. Each payment (including, without limitation,
  prepayments) made on this Note shall be credited first, to any fees, costs or
  expenses outstanding under the Loan Documents, second, to interest then due
  and third, to the outstanding principal balance hereof. All payments credited
  to principal shall be applied first, to the outstanding principal balance of
  this Note which bears interest determined in relation to the Prime Rate, if
  any, and second, to the outstanding principal balance of this Note which bears
  interest determined in relation to LIBOR, with such payments applied to the
  oldest Fixed Rate Term first. 

 EVENTS OF DEFAULT: 

      This Note is made pursuant
  to and is subject to the terms and conditions of the Credit Agreement. Any Event
  of Default (as that term is defined in the Credit Agreement) shall constitute
  an “Event of Default” hereunder. 

 GENERAL PROVISIONS: 

      (a)    
  Successors, Assignment. This Note shall be binding upon and inure to
  the benefit of the heirs, executors, administrators, legal representatives,
  successors and assigns of Borrower and the holder hereof; provided that
  Borrower may not assign or transfer its interest hereunder without the express
  prior written consent of the holder hereof.

      (b)    
  Entire Agreement;
  Amendment. This Note and the other Loan Documents constitute
  the entire agreement between Borrower and Bank with respect to each credit subject
  hereto and supersede all prior negotiations, communications, discussions and
  correspondence concerning the subject matter hereof. This Note may be amended
  or modified only in writing signed by Borrower and the holder hereof.

 SECURITY AGREEMENT:
  SECURITIES ACCOUNT 

     
  1.     GRANT OF SECURITY INTEREST. For valuable consideration,
  the undersigned WIND RIVER SYSTEMS, INC., a Delaware corporation (“Debtor”),
  hereby grants and transfers to WELLS FARGO BANK, NATIONAL ASSOCIATION (“Bank”)
  a security interest in (a) Debtor’s Account No. 12737300 (whether held in Debtor’s
  name or as a Bank collateral account for the benefit of Debtor), and all replacements
  or substitutions therefor, including any account resulting from a renumbering
  or other administrative re-identification thereof (collectively, the “Securities
  Account”) maintained with Wells Fargo Institutional Securities, LLC (“Intermediary”),
  (b) all financial assets credited to the Securities Account, (c) all security
  entitlements with respect to the financial assets credited to the Securities
  Account, and (d) any and all other investment property or assets maintained
  or recorded in the Securities Account (with all the foregoing defined as “Collateral”),
  together with whatever is receivable or received when any of the Collateral
  or proceeds thereof are sold, collected, exchanged or otherwise disposed of,
  whether such disposition is voluntary or involuntary, including without limitation,
  (i) all rights to payment, including returned premiums, with respect to any
  insurance relating to any of the foregoing, (ii) all rights to payment with
  respect to any claim or cause of action affecting or relating to any of the
  foregoing, and (iii) all stock rights, rights to subscribe, stock splits, liquidating
  dividends, cash dividends, dividends paid in stock, new securities or other
  property of any kind which Debtor is or may hereafter be entitled to receive
  on account of any securities pledged hereunder, including without limitation,
  stock received by Debtor due to stock splits or dividends paid in stock or sums
  paid upon or in respect of any securities pledged hereunder upon the liquidation
  or dissolution of the issuer thereof (hereinafter called “Proceeds”). Except
  as otherwise expressly permitted herein, in the event Debtor receives any such
  Proceeds, Debtor will hold the same in trust on behalf of and for the benefit
  of Bank and will immediately deliver all such Proceeds to Bank in the exact
  form received, with the endorsement of Debtor if necessary and/or appropriate
  undated stock powers duly executed in blank, to be held by Bank as part of the
  Collateral, subject to all terms hereof. As used herein, the terms “control,”
  “security entitlement,” “financial asset” and “investment property” shall have
  the respective meanings set forth in the California Uniform Commercial Code.
  In addition, each other capitalized term used but not otherwise defined herein
  has the meaning ascribed thereto in that certain Credit Agreement, dated as
  of April 15, 2003 (as amended, supplemented and/or otherwise modified from time
  to time, the “Credit Agreement”), entered into between Bank and Debtor. 

      2.     OBLIGATIONS
  SECURED. The obligations secured hereby are the payment and performance of all
  Obligations.

      3.     TERMINATION.
  This Agreement will terminate upon the performance of all obligations of Debtor
  to Bank secured hereby, and the termination of all commitments of Bank to extend
  credit to Debtor that are secured hereby, existing at the time Bank receives
  written notice from Debtor of the termination of this Agreement. 

      4.     OBLIGATIONS
  OF BANK. Bank shall have no duty to take any steps necessary to preserve the
  rights of Debtor against prior parties, or to initiate any action to protect
  against the possibility of a decline in the market value of the Collateral or
  Proceeds. Bank shall not be obligated to take any action with respect to the
  Collateral or Proceeds requested by Debtor unless such request is made in writing
  and Bank determines, in its sole discretion, that the requested action would
  not unreasonably jeopardize the value of the Collateral and Proceeds as security
  for the Obligations.

 -1-

  
     
  5.     REPRESENTATIONS AND WARRANTIES. Debtor represents
  and warrants to Bank that: (a) Debtor’s legal name is exactly as set forth on

  or agreements delivered to Bank are complete and accurate in every respect;
  (b) Debtor is the sole owner of the Collateral and Proceeds; (c) Debtor has
  the exclusive right to grant a security interest in the Collateral and Proceeds;
  (d) all Collateral and Proceeds are genuine, free from liens, adverse claims,

  or character, except for Permitted Liens; (e) except in respect of Permitted
  Liens, no financing statement covering any of the Collateral or Proceeds, and
  naming any secured party other than Bank, exists or is on file in any public
  office or remains in effect; and (f) no person or entity, other than Debtor,
  Bank and Intermediary, has any control over the Collateral or Proceeds. 

     6.     COVENANTS
  OF DEBTOR.

     (a)     Debtor
  agrees in general: (i) to pay Indebtedness secured hereby when due; (ii)
  to indemnify Bank against
  all losses, claims, demands, liabilities and expenses of every kind caused by

  giving Bank notice within thirty (30) days thereof; and (vii) to cooperate with
  Bank in perfecting all security interests granted herein and in obtaining such
  agreements from third parties as Bank deems reasonably necessary in connection
  with the preservation, perfection or enforcement of any of its rights hereunder.
  

      (b)     Debtor
  agrees with regard to the Collateral and Proceeds, unless Bank agrees otherwise
  in writing: (i) that Bank is authorized to file financing statements in the
  name of Debtor to perfect Bank’s security interest in Collateral and Proceeds;
  (ii) not to permit any security interest in or lien on the Collateral or Proceeds,
  except for Permitted Liens; provided that in no event shall Debtor grant control

  than Intermediary on behalf of Bank; (iii) except for Permitted Liens, not to
  hypothecate or permit the transfer by operation of law of any of the Collateral
  or Proceeds or any interest therein; provided
  that in no event shall Debtor grant control over the Collateral and/or the Proceeds
  to any other person or entity other than Intermediary (on behalf of Bank); and
  (iv) if the Collateral or Proceeds consists of securities and so long as no
  Event of Default has occurred and is continuing unwaived, to vote said securities
  and to give consents, waivers and ratifications with respect thereto, provided
  that no vote shall be cast or consent, waiver or ratification given or action
  taken which would impair Bank’s interests in the Collateral and Proceeds or
  be inconsistent with or violate any provisions of this Agreement. Debtor further
  agrees that any party now or at any time hereafter authorized by Debtor to advise
  or otherwise act with respect to the Securities Account shall be subject to
  all terms and conditions contained herein and in any control, custodial or other
  similar agreement at any time in effect among Bank, Debtor and Intermediary
  relating to the Collateral. 

     
  7.     POWERS OF BANK. Debtor appoints Bank its true attorney
  in fact to perform any of the following powers, which are coupled with an interest,
  are irrevocable until termination of this Agreement and may be exercised from
  time to time by Bank’s officers and employees, or

 -2- 

  
 any of them, whether or not
  Debtor is in default (except as otherwise provided): (a) to perform any obligation
  of Debtor hereunder in Debtor’s name or otherwise; (b) if an Event of Default
  has occurred and is continuing unwaived, to notify any person obligated on any
  security, instrument or other document subject to this Agreement of Bank’s rights
  hereunder; (c) if an Event of Default has occurred and is continuing unwaived,
  to collect by legal proceedings or otherwise all dividends, interest, principal
  or other sums now or hereafter payable upon or on account of the Collateral
  or Proceeds; (d) if an Event of Default has occurred and is continuing unwaived,
  to enter into any extension, modification, reorganization, deposit, merger or
  consolidation agreement, or any other agreement relating to or affecting the
  Collateral or Proceeds, and in connection therewith to deposit or surrender
  control of the Collateral and Proceeds, to accept other property in exchange
  for the Collateral and Proceeds, and to do and perform such acts and things
  as Bank may deem proper, with any money or property received in exchange for
  the Collateral or Proceeds, at Bank’s option, to be applied to the Indebtedness
  or held by Bank under this Agreement; (e) if an Event of Default has occurred
  and is continuing unwaived, to make any compromise or settlement Bank deems
  desirable or proper in respect of the Collateral and Proceeds; (f) if an Event
  of Default has occurred and is continuing unwaived, to insure, process and preserve
  the Collateral and Proceeds; (g) if an Event of Default has occurred and is
  continuing unwaived, to exercise all rights, powers and remedies which Debtor
  would have, but for this Agreement, with respect to all Collateral and Proceeds
  subject hereto; and (h) to do all acts and things and execute all documents
  in the name of Debtor or otherwise deemed by Bank (acting in good faith) as
  necessary, proper and convenient in connection with the preservation, perfection
  or enforcement of its rights hereunder. If an Event of Default has occurred
  and is continuing unwaived, to effect the purposes of this Agreement or otherwise
  upon instructions of Debtor, Bank may cause any Collateral and/or Proceeds to
  be transferred to Bank’s name or the name of Bank’s nominee. If an Event of
  Default has occurred and is continuing unwaived, any or all Collateral and/or
  Proceeds consisting of securities may be registered, without notice, in the
  name of Bank or its nominee, and thereafter Bank or its nominee may exercise,
  without notice, all voting and corporate rights at any meeting of the shareholders
  of the issuer thereof, any and all rights of conversion, exchange or subscription,
  or any other rights, privileges or options pertaining to such Collateral and/or
  Proceeds, all as if it were the absolute owner thereof. The foregoing shall
  include, without limitation, the right of Bank or its nominee to exchange, at
  its discretion, any and all Collateral and/or Proceeds upon the merger, consolidation,
  reorganization, recapitalization or other readjustment of the issuer thereof,
  or upon the exercise by the issuer thereof or Bank of any right, privilege or
  option pertaining to any shares of the Collateral and/or Proceeds, and in connection
  therewith, the right to deposit and deliver any and all of the Collateral and/or
  Proceeds with any committee, depository, transfer agent, registrar or other
  designated agency upon such terms and conditions as Bank may determine. All
  of the foregoing rights, privileges or options may be exercised without liability
  on the part of Bank or its nominee except to account for property actually received
  by Bank. Bank shall have no duty to exercise any of the foregoing, or any other
  rights, privileges or options with respect to the Collateral or Proceeds and
  shall not be responsible for any failure to do so or delay in so doing. 

      8.     PAYMENT
  OF PREMIUMS, TAXES, CHARGES, LIENS AND ASSESSMENTS. Debtor agrees to pay, prior
  to delinquency, all insurance premiums, taxes, charges, liens and assessments
  against the Collateral and Proceeds, and upon the failure of Debtor to do so,
  Bank at its option may pay any of them and shall be the sole judge of the legality
  or validity thereof and the amount necessary to discharge the same. Any such
  payments made by Bank shall be obligations of Debtor to Bank, due and payable
  immediately upon demand, together with interest at a rate determined in accordance
  with the provisions of Section 15 hereof, and shall 

 -3-

  
 be secured by the Collateral
  and Proceeds, subject to all terms and conditions of this Agreement. 

      9.     EVENTS
  OF DEFAULT. The occurrence of any “Event of Default” as that term is defined
  in the Credit Agreement shall constitute an “Event of Default” hereunder. 

      10.    
  REMEDIES. Upon the occurrence and during the continuation of any unwaived Event
  of Default, Bank shall have the right to declare immediately due and payable
  all or any Indebtedness secured hereby and to terminate any commitments to make
  loans or otherwise extend credit to Debtor. Bank shall have all other rights,
  powers, privileges and remedies granted to a secured party upon default under
  the California Uniform Commercial Code or otherwise provided by law, including
  without limitation, the right (a) to contact all persons obligated to Debtor
  on any Collateral or Proceeds and to instruct such persons to deliver all Collateral
  and/or Proceeds directly to Bank, and (b) to sell, lease, license or otherwise
  dispose of any or all Collateral. All rights, powers, privileges and remedies
  of Bank shall be cumulative. No delay, failure or discontinuance of Bank in
  exercising any right, power, privilege or remedy hereunder shall affect or operate
  as a waiver of such right, power, privilege or remedy; nor shall any single
  or partial exercise of any such right, power, privilege or remedy preclude,
  waive or otherwise affect any other or further exercise thereof or the exercise
  of any other right, power, privilege or remedy. Any waiver, permit, consent
  or approval of any kind by Bank of any default hereunder, or any such waiver
  of any provisions or conditions hereof, must be in writing and shall be effective
  only to the extent set forth in writing. It is agreed that public or private
  sales or other dispositions, for cash or on credit, to a wholesaler or retailer
  or investor, or user of property of the types subject to this Agreement, or
  public auctions, are all commercially reasonable since differences in the prices
  generally realized in the different kinds of dispositions are ordinarily offset
  by the differences in the costs and credit risks of such dispositions. If an
  Event of Default has occurred and is continuing unwaived: (a) Debtor will not
  dispose of any Collateral or Proceeds except on terms approved by Bank; (b)
  Bank may appropriate the Collateral and apply all Proceeds toward repayment
  of the Indebtedness in such order of application as Bank may from time to time
  elect; (c) Bank may take any action with respect to the Collateral contemplated
  by any control, custodial or other similar agreement then in effect among Bank,
  Debtor and Intermediary; and (d) at Bank’s request, Debtor will assemble and
  deliver all books and records pertaining to the Collateral or Proceeds to Bank
  at a reasonably convenient place designated by Bank. For any Collateral or Proceeds
  consisting of securities, Bank shall have no obligation to delay a disposition
  of any portion thereof for the period of time necessary to permit the issuer
  thereof to register such securities for public sale under any applicable state
  or Federal law, even if the issuer thereof would agree to do so. Debtor further
  agrees that Bank shall have no obligation to process or prepare any Collateral
  for sale or other disposition. 

      11.    
  DISPOSITION OF COLLATERAL AND PROCEEDS; TRANSFER OF INDEBTEDNESS. In disposing
  of Collateral hereunder, Bank may disclaim all warranties of title, possession,
  quiet enjoyment and the like. Any proceeds of any disposition of any Collateral
  or Proceeds, or any part thereof, may be applied by Bank to the payment of expenses
  incurred by Bank in connection with the foregoing, including reasonable attorneys’
  fees, and the balance of such proceeds may be applied by Bank toward the payment
  of the Indebtedness in such order of application as Bank may from time to time
  elect. Upon the transfer of all or any part of the Indebtedness, Bank may transfer
  all or any part of the Collateral or Proceeds and shall be fully discharged
  thereafter from all liability and responsibility with respect to any of the
  foregoing so transferred, and the transferee shall be vested with all rights
  and powers of Bank hereunder with respect to any of the foregoing so transferred;
  but with respect to any Collateral 

 -4- 

  
 or Proceeds not so transferred,
  Bank shall retain all rights, powers, privileges and remedies herein given.
  

      12.     STATUTE
  OF LIMITATIONS. Until all Indebtedness shall have been paid in full and all
  commitments by Bank to extend credit to Debtor have been terminated, the power
  of sale or other disposition and all other rights, powers, privileges and remedies
  granted to Bank hereunder shall continue to exist and may be exercised by Bank
  at any time and from time to time irrespective of the fact that the Indebtedness
  or any part thereof may have become barred by any statute of limitations, or
  that the personal liability of Debtor may have ceased, unless such liability
  shall have ceased due to the payment in full of all Indebtedness secured hereunder.
  

      13.      MISCELLANEOUS.
  Debtor hereby waives any right to require Bank to (i) proceed against Debtor
  or any other person, (ii) proceed against or exhaust any security from Debtor
  or any other person, (iii) perform any obligation of Debtor with respect to
  any Collateral or Proceeds, and (d) make any presentment or demand, or give
  any notice of nonpayment or nonperformance, protest, notice of protest or notice
  of dishonor hereunder or in connection with any Collateral or Proceeds. Debtor
  further waives any right to direct the application of payments or security for
  any Indebtedness of Debtor or indebtedness of customers of Debtor. 

      14.     NOTICES.
  All notices, requests and demands required under this Agreement shall be made,
  and shall be deemed given or received, given in accordance with the provisions
  of the Credit Agreement. 

      15.     COSTS,
  EXPENSES AND ATTORNEYS’ FEES. Debtor shall pay to Bank immediately upon demand
  the full amount of all payments, advances, charges, costs and expenses, including
  reasonable attorneys’ fees (to include outside counsel fees and all allocated
  costs of Bank’s in-house counsel), expended or incurred by Bank in exercising
  any right, power, privilege or remedy conferred by this Agreement or in the
  enforcement thereof, whether incurred at the trial or appellate level, in an
  arbitration proceeding or otherwise, and including any of the foregoing incurred
  in connection with any bankruptcy proceeding (including without limitation,
  any adversary proceeding, contested matter or motion brought by Bank or any
  other person) relating to Debtor or in any way affecting any of the Collateral
  or Bank’s ability to exercise any of its rights or remedies with respect thereto.
  All of the foregoing shall be paid by Debtor with interest from the date of
  demand until paid in full at a rate per annum equal to the Prime Rate (as defined
  in the Loan Commitment Note) in effect from time to time plus three percent
  (3.0%). 

      16.    
  SUCCESSORS; ASSIGNS; AMENDMENT. This Agreement shall be binding upon and inure
  to the benefit of the heirs, executors, administrators, legal representatives,
  successors and assigns of the parties, and may be amended or modified only in
  writing signed by Bank and Debtor. 

      17.     SEVERABILITY
  OF PROVISIONS. If any provision of this Agreement shall be held to be prohibited
  by or invalid under applicable law, such provision shall be ineffective only
  to the extent of such prohibition or invalidity, without invalidating the remainder
  of such provision or any remaining provisions of this Agreement. 

      18.     GOVERNING
  LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
  INTERNAL LAWS OF THE STATE OF CALIFORNIA.
