     3.6  Licensed Program. HP shall not be an owner of any copies of the
          licensed Program, but, rather, is licensed pursuant to this agreement
          to use such copies. HP acknowledges and agrees that, as between HP and
          Licensor, all right, title, and interest in the Program and any part
          thereof, including, without limitation, all rights to patent,
          copyright, trademark and trade secret rights and all other
          intellectual property rights therein and thereto, and all copies
          thereof, in whatever form, including any written documentation and all
          other material describing such Program, shall at all times remain
          solely with Licensor.

     3.7  Licensee Modification. Notwithstanding the forgoing, Licensee shall
          retain all right, title and interest in and to modifications to the
          Program made by Licensee pursuant to the license in Section 3 above,

     4.1  Maintenance and Support.

          (a)  Licensor agrees to provide HP with ongoing maintenance and
               support for the Program and other software supplied under this
               Agreement as set forth in Exhibit C hereto. Licensor agrees to
               maintain such number of qualified personnel as is necessary to
               provide such timely and knowledgeable maintenance and support
               service. Annual minimum support fee requirements are defined in
               Exhibit B.

          (b)  Notwithstanding any termination of this Agreement, Licensor
               agrees to maintain and support the Program distributed by HP for
               at least [*] ([*]) years after such Program is included in a HP
               Product for distribution hereunder, provided that HP maintains an
               annual support dollar minimum of $[*] or enters into a [*]

     4.2  Technical Assistance and Training.  Licensor agrees to provide to HP
          such technical assistance and training to HP personnel as may be
          reasonably requested in order for HP to use, reproduce, bundle and
          distribute the Program as contemplated herein, as further set forth in
          Exhibit D.


     4.3  Functionality Enhancements. It is expected that the Licensor shall
          through the duration of this agreement continually enhance the
          Program's functionality (enhancements, revisions and versions) to
          remain among the leaders in their given field of technology as part of
          their normal course of business. Licensor will conduct quarterly
          meetings with HP to review their technology roadmap and delivery dates
          for such roadmap. At these meetings, HP will be able to provide input
          on the Licensor's technology roadmap. Licensor shall consider making
          commercially reasonable efforts in meeting the technology needs of HP
          for which HP has substantial dependency. HP and Licensor shall
          mutually agree on acceptance testing for any and each new program
          functionality. HP may, however, from time to time request significant
          functionality enhancements to the Program which are outside of the
          Licensor's technology roadmap or the roadmap's time frames. Licensor
          agrees to develop these enhancements if both parties agree to the
          enhancement proposal, which may provide for additional NRE payments by
          HP to Licensor. [*] Prior to commencing work, Licensor will provide HP
          with a written estimate of the total fee for the proposed enhancement
          and the final fee shall not exceed the estimate by more than fifteen
          percent (15%) unless mutually agreed to by HP and Licensor.


             5.1  Royalty.  In consideration for the rights and licenses granted
          to HP under this Agreement, HP agrees to pay Licensor a Per Copy Fee
          royalty for each copy of the Run Time Software that HP distributes as
          bundled with the HP Product (net after returns), in the amount set
          forth in Exhibit B. Enhancements to the Run Time Software's
          functionality (enhancements, revisions and versions) are [*] as set
          forth in Exhibit B. Such royalty will [*] the right to [*] appropriate
          Documentation. [*]. The "Run Time Update Right" fee detailed in
          Exhibit B gives HP the right to update existing Run Time Software
          customers with the latest Revision or new Version of the Run Time
          Software. [*]. Other fees for LynxOS Development System Licenses and
          LynxOS Source Code Licenses including annual maintenance and support
          are also detailed in Exhibit B.

     5.2  Payment.  A Per Copy Fees will accrue on the date that a Royalty
          Generating Unit is shipped or in the case of a Revision or new Version
          of the Run Time Software shipped to existing customers, when that
          distribution occurs. All accrued Per Copy Fees will be paid by HP to
          Licensor within thirty five (35) days after the end of each HP fiscal
          quarter, which ends on the last day of each January, April, July and
          October. Payments will be accompanied by a report stating the number
          of copies of the Run Time Software, Revision or new Version
          distributed in the relevant quarter, and the calculation for the
          royalty payment. All other Fees will be paid to Licensor within forty
          (40) days after receipt of invoice. All such invoices shall reference
          a valid purchase order number issued by HP.

     5.3  Audit.  Upon fifteen (15) days prior written notice to HP, Licensor
          may, at its own expense, appoint a nationally recognized independent
          auditor, to whom HP has no reasonable objection, to audit and examine
          such records at HP's offices during normal business hours, solely for
          the purpose of confirming the accuracy of royalty payments hereunder.
          Such auditor shall be subject to an appropriate non-disclosure
          agreement executed prior to any such audit. Such audit may be made no
          more often than once every twelve calendar month period. Should an
          audit discover any errors or omissions by HP amounting to more than 5%
          of the amount due during any given period audited, HP shall reimburse
          Licensor for the cost of the audit.



     5.4  [*]. Licensor warrants that the amounts payable hereunder by HP are
          [*] than [*] of licenses for those versions of the Run Time Software
          for shipment in [*].
     5.5  Taxes.  Licensor shall be solely responsible for taxes on amounts paid
          to Licensor by HP under this Agreement, including all state and local
          use, sales, property (ad valorem) and similar taxes, provided that HP
          provides Licensor with an appropriate reseller certificate.


     6.1  General Warranty.  Licensor warrants that it owns or has licensed all
          rights to each Program and accompanying Documentation, including all
          portions thereof (except as described in section 3.5), and that such
          interests are free of any and all restrictions, settlements, judgments
          or adverse claims. Licensor warrants it has full power and authority
          to grant HP the rights granted herein including the right to use,
          reproduce and distribute each Program and appropriate Documentation
          worldwide and to authorize third parties to do the same.

     6.2  Program Warranty.  Licensor warrants that each Program will operate in
          accordance with and substantially conform to the specifications set
          forth in the Product Description and Specifications as set out in
          Exhibit A of the Lynx/HP Product Development Agreement or as
          subsequently modified by mutual agreement of the parties. In the event
          of a non-compliance, HP's remedy is to have the issue resolved under
          the "Maintenance and Support" of Exhibit C.

     6.3  Date Processing Compliant. Licensor warrants that the Lynx OS Run Time
          Software is date processing compliant for issues arising within the
          term of this agreement (i.e. Year 2000). Date processing compliant
          programs will perform without error, loss of data or loss of
          functionality arising from any failure to process, calculate, compare
          or sequence date data accurately. In addition, date processing
          compliant products will not cause any associated products or systems
          in which they may be used to fail in any of described above. A
          specific year 2000 Compliance Warranty will remain in effect through
          December 31, 2000, notwithstanding any other warranty period specified
          in this Agreement. In the event of a non-compliance, HP's remedy is to
          have the issue resolved under the "Maintenance and Support" of Exhibit

     6.4   [*]    Should any claim or breach arise under 6.1, 6.5 or 6.6, HP
          shall have the [*] to [*] of any [*] under this Agreement. HP agrees
          to place the same in [*] or [*]
     6.5  No Infringement.  Licensor warrants that the Program, Documentation,
          trademarks, copyrights and trade names related to the Program do not
          violate or infringe any patent, copyright, trade secret or other
          proprietary right of any third party and that Licensor is not aware of
          any facts upon which such a claim for infringement could be based.

     6.6  Infringement Indemnity. Licensor will indemnify, hold harmless and
          defend any claim, suit, or proceeding brought against HP or its
          customers insofar as it is based on a claim that the Program or
          Documentation, or any part thereof, furnished by Licensor under this
          Agreement constitutes an infringement of any third party's patent,
          copyright, trademark, trade name, or unauthorized trade secret use;
          provided that Licensor is notified promptly in writing of such claim,
          and given authority, information and assistance (at Licensor's
          expense) to handle the defense and/or settlement of any such claim,
          suit or proceeding. Licensor agrees to pay all damages and costs
          awarded therein against HP and its customers.

          In case any Program or Documentation or any part thereof in such suit
          is held to constitute an infringement and its use is enjoined,
          Licensor shall, at its own expense and at its option, either procure
          for HP and its customers the right to continue use or, if applicable,
          replace the same with a non-infringing program and documentation of
          equivalent function and performance, or modify them so they become
          non-infringing without detracting from function or performance.

          Notwithstanding the foregoing, Licensor shall have no responsibility
          for claims arising from (i) modifications of the Program made by HP if
          such claim would not have arisen but for such



          modifications, or (ii) combination or use of the Program with HP
          Products if such claim would not have arisen but for such combination
          or use.



     7.1  Term. Unless otherwise terminated earlier under this Section 7, this
          Agreement shall commence as of the date first set forth above, and
          shall continue for a period of five (5) years after such date. This
          Agreement will renew automatically for additional one (1) year periods
          unless written notice is given by one party to the other as to its
          intention not to renew this Agreement at least thirty (30) days prior
          to the end of the initial or any subsequent term.

     7.2  Termination for Breach.  Either party may terminate this Agreement by
          written notice to the other party if the other party breaches any
          material provision of this Agreement and such breach is not cured
          within sixty (60) days after written notice thereof is received by the
          breaching party. This Agreement is predicated on "HP-Lynx Product
          Development Agreement" being successfully completed. Failure to
          complete the "HP-Lynx Product Development Agreement" shall be
          considered breach and grounds to terminate this SOFTWARE LICENSE
          AGREEMENT. Failure to comply with support obligations under this
          Agreement will be considered breach and grounds to terminate this
          Software License Agreement.

     7.3  Effect of Termination.  Notwithstanding any termination of this
          Agreement, all licenses granted to end users prior to the date of
          termination for use of the Run Time Software shall survive. In the
          event that this Agreement is terminated by HP due to breach by
          Licensor, the licenses granted to HP under Section 3 shall survive so
          long as HP continues to pay Licensor the applicable Per Copy Fees
          under Section 5.

     7.4  Survival.  Notwithstanding any termination of this Agreement, the
          following provisions of this Agreement shall survive for the relevant
          period of time set forth therein, if any: Sections 3.5, 3.6 (Rights
          Granted and Restrictions), 4.1 (Support), 5.1, 5.2, 5.3 (Payment), 6

     9.1  The Program. All Programs in object code form and related
          Documentation provided to HP hereunder are deemed non-confidential,
          and HP is not under any obligation to Licensor to restrict access to
          or use of such Programs in object code form or related Documentation,
          provided HP otherwise complies with the terms of this Agreement.

     9.2  Confidential Information. During the term of this Agreement, either
          party may receive or have access to technical information, as well as
          information about product plans and strategies, promotions, customers
          and related non-technical business information which the disclosing
          party considers to be confidential ("confidential information"). In
          the event such information is disclosed, the parties shall first agree
          to disclose and receive such information in confidence. If then
          disclosed, the information shall (i) be marked as confidential at the
          time of disclosure, or (ii) if disclosed orally but stated to be
          confidential, be designated as confidential in a writing by the
          disclosing party summarizing the confidential information disclosed
          and sent to the receiving party within a reasonable period of time
          after such oral disclosure. Notwithstanding any provision to the
          contrary, all source code provided by either party to the other, and
          all business information with respect to any unpublished or future
          Licensor or HP products, are deemed confidential information for the
          purposes of this Section 9.

     9.3  Nondisclosure. Confidential information may be used by the receiving
          party only with respect to performance of its obligations under this
          Agreement, and only by those employees of the receiving party who have
          a need to know such information for purposes related to this
          Agreement. The receiving party shall protect the Confidential
          Information of the disclosing party by using the same degree of care
          (but not less than a reasonable degree of care) to prevent the
          unauthorized use, dissemination or publication of such Confidential
          Information, as the receiving party uses to protect its own
          confidential information of like nature. The receiving party's
          obligation under this Section 9 shall be for a period of three (3)
          years after the date of disclosure except for either parties' source
          code which shall be held confidential in perpetuity. The foregoing
          obligation shall not apply to any information which is: (i) already
          known by the receiving party prior to disclosure; (ii) publicly
          available through no fault of the receiving party; (iii) rightfully
          received from a third party without a duty of confidentiality; (iv)
          disclosed by the disclosing party to a third party without a duty of
          confidentiality on such third party; (v) independently developed by
          the receiving party prior to or independent of the disclosure; (vi)
          disclosed under operation of law; or (vii) disclosed by the receiving
          party with the disclosing party's prior written approval.

     9.4  Notification. Each party agrees to notify the other promptly on the
          event of any breach of security under conditions in which it would
          appear that any confidential information was prejudiced or exposed to
          loss. Each party shall, upon request of the other, take all other
          reasonable steps necessary to recover any compromised confidential
          information disclosed to or placed in the possession of each party by
          virtue of this Agreement. Each party shall individually bear the cost
          of taking any such steps.

     9.5  Remedies. Each party acknowledges that any breach of any of its
          obligations under this section 9 is likely to cause or threaten
          irreparable harm to the other, and accordingly, agree that in such
          event, the aggrieved party shall be entitled to equitable relief to
          protect its interest therein, which will be limited to preliminary and
          permanent injunctive relief for both HP and Licensor but will not
          limit the aggrieved party from seeking expanded remedies from other
          unrelated third parties.


     10.1  Publicity.  Each party agrees not to publicize or disclose the
          existence or terms of this Agreement to any third party (except as
          allowed in this agreement in section 3) without the prior written


            consent of the other except as required by law. In particular, no
            press releases shall be made without the mutual written consent of
            each party.

     10.2   Independent Contractors.  The relationship of the parties under this
            Agreement is that of independent contractors, and neither party is
            an employee, agent, partner or joint venturer of the other.

     10.3   Relationship Managers.  Each party designates the person(s) set 
            forth in Exhibit E as the primary contact(s) of each party with 
            respect to this Agreement, which person(s) may be redesignated by a
            party by notice to the other.

     10.4   Dispute Resolution.  In the event of disagreement with respect to 
            any aspect of this Agreement, the parties agree to discuss in good-
            faith to reach an amicable resolution, and to escalate such
            resolution process to the appropriate members of their respective
            management organization who have the power and authority to achieve
            a successful resolution.

     10.5   Notice.  Unless otherwise stated, all notices required under this
            Agreement shall be in writing and shall be considered given upon
            personal delivery of the written notice or within forty eight (48)
            hours after deposit in the U.S. Mail, certified or registered, and
            addressed to the appropriate relationship manager as set forth in
            Exhibit E.

     10.6   No Assignment.  Neither party may assign or transfer any of the
            rights or responsibilities set forth herein, or change its control
            of ownership, without the express written consent of the other party
            (which consent shall not be unreasonably withheld or delayed) and
            any purported attempt to do so shall be deemed void.

     10.7   Governing Law.  This Agreement is made under and shall be construed
            in accordance with the law of the State of California, without
            reference to conflict of laws principles. Any claim or suit with
            respect to this Agreement shall be brought in the jurisdiction in
            which the non-complaining party resides.

     10.8   Severability.  The terms of this Agreement shall be applicable
            severally to each Program, if more than one, and any dispute
            affecting either party's rights or obligations as to one or more
            Program(s) shall not affect the rights granted hereunder as to any
            other Program. If any provision of this Agreement is held to be
            invalid or unenforceable by a court of competent jurisdiction, then
            the remaining provisions will nevertheless remain in full force and
            effect, and the parties will negotiate in good-faith a substitute,
            valid and enforceable provision which most nearly effects the
            parties' intent in entering into this Agreement.

     10.9   Headings.  The captions and headings used in this Agreement are for
            convenience in reference only, and are not to be construed in any
            way as terms or be used to interpret the provisions of this

     10.10  No Distribution Obligation.  Except as expressly provided herein, HP
            may in its sole discretion decide to distribute or not distribute
            the Program as it deems appropriate. Nothing in this Agreement shall
            be construed or interpreted as placing a "best efforts" standard
            upon HP with respect to the use and distribution of the Program, or
            placing any minimum obligation to pay Per Copy Fees.

     10.11  Non-Restrictive Relationship.  Nothing in this Agreement shall be
            construed to preclude HP from independently developing, acquiring
            from other third parties, distributing or marketing software
            programs or other products which may perform the same or similar
            functions as the Programs provided under this Agreement. Except that
            HP itself or other third parties they contract with to provide the
            same or similar functions may not reverse engineer, decompile,
            disassemble or use the Source Code provided under this Agreement to
            develop such products or programs.

     10.12  Modifications.  This Agreement may be modified only by a writing
            signed by an authorized representative of each party.


     10.13  Waiver.  Neither party's failure to exercise any of its rights
            hereunder shall constitute or be deemed a waiver or forfeiture of
            any such rights.

     10.14  Force Majeure.  Nonperformance of either party will be excused to
            the extent that performance is rendered impossible by strike, fire,
            flood, governmental acts or orders or restrictions or other similar
            reason where failure to perform is beyond the control and not caused
            by the negligence of the non-performing party, provided that the 
            non-performing party gives prompt notice of such conditions to the
            other party and makes all reasonable efforts to perform.

     10.15  Export Control.  Each party agrees to comply with all applicable
            United States laws and regulations which may govern the export of
            Program abroad, including the Export Administration Act of 1979, as
            amended, any successor legislation, and the Export Administration
            Regulations issued by the Department of Commerce.

     10.16  Entire Agreement.  This document represents the entire agreement
            between the parties as to the matters set forth herein and
            supersedes all prior discussions, representations or understandings
            between them.

     10.17  Exhibits.  Each of the following Exhibits referred to in this
            Agreement is incorporated in full in this Agreement wherever
            reference to it is made:

HP LSG Boise anticipates a requirement for [*] Lynx Open Development Seats (ODEC) in support of both the applications porting efforts and custom board support porting efforts. Hewlett Packard - Boise will purchase a minimum of [*] ODEC's prior to [*] using the [*] to [*] price schedule as depicted above. After [*] HP LSG Boise will purchase at a minimum, another [*] ODEC's within the next [*] month period ([*] to [*]) using the [*] to [*] price schedule as depicted above, and although anticipates maintaining [*] ODEC licenses at a minimum for the length of the contract term, pricing will be based on the actual maximum numbers of seats per year. Lynx will allow Hewlett Packard - Boise to pro-rate all Lynx product maintenance so these product maintenance periods may coincide with Hewlett Packard's fiscal year calendar. HP can convert the Intel X86 licenses to [*] at their [*]. [*] licenses are formatter target independent. Lynx Operating System Source Code --------------------------------- Lynx Real-Time Systems will make available completely buildable source code versions of its product offering.
