reimbursement or damages on account of the loss of prospective profits or
anticipated sales or on account of expenditures, inventory, investments, leases
or commitments in connection with the business or goodwill of Lynx or
Distributor. Termination shall not, however, relieve either party of obligations
incurred prior to the termination.

     9..7   Survival of Certain Terms. The provisions of Sections 4.6, 6, 9, 10,
            -------------------------

10.  LIMITED LIABILITY TO DISTRIBUTOR AND OTHERS
     -------------------------------------------

     10..1  LYNX'S LIABILITY UNDER ANY CAUSE OF ACTION ARISING UNDER THIS
AGREEMENT OR UNDER ANY INDEMNITY CONTAINED IN THIS AGREEMENT SHALL NOT EXCEED
THE AMOUNTS RECEIVED BY LYNX FROM DISTRIBUTOR UNDER THIS AGREEMENT.

     10..2  IN NO EVENT SHALL LYNX HAVE ANY LIABILITY TO DISTRIBUTOR OR TO END
USERS OR ANY OTHER THIRD PARTY, FOR ANY LOST PROFITS OR COSTS OF PROCUREMENT OF
SUBSTITUTE GOODS OR SERVICES, OR FOR ANY OTHER INDIRECT, SPECIAL OR
CONSEQUENTIAL DAMAGES RESULTING FROM THE USE OF THE LICENSED PRODUCTS, OR THE
FAILURE OF THE LICENSED PRODUCTS TO PERFORM, OR FOR ANY OTHER REASON; PROVIDED,
HOWEVER, THAT THIS LIMITATION SHALL NOT APPLY TO ANY BREACH OF THE
CONFIDENTIALITY OBLIGATIONS SET FORTH IN SECTION 11 BELOW OR TO DISTRIBUTOR'S
EXCEEDING ITS AUTHORITY GRANTED. IT IS ACKNOWLEDGED BY THE PARTIES THAT NOTHING
IN THIS SECTION 10 SHALL LIMIT A PARTY'S OBLIGATION TO PAY AMOUNTS ALREADY DUE
AND OWING TO THE OTHER PARTY. THESE LIMITATIONS SHALL APPLY NOTWITHSTANDING THE
FAILURE OF THE ESSENTIAL PURPOSE OF ANY LIMITED REMEDY.

11.  PROPERTY RIGHTS AND CONFIDENTIALITY
     -----------------------------------

     11..1  Property Rights.  Except as granted hereunder or under End User
            ---------------
License, Distributor agrees that Lynx owns all right, title, and interest in the
Software and in each Software Copies now or hereafter subject to this Agreement
and in all of Lynx's patents, trademarks, trade names, inventions, copyrights,
know-how, and trade secrets relating to the design, manufacture,

                                      11
<PAGE>

operation or service of the Software Copies. The use by Distributor of any of
these property rights is authorized only for the purposes herein set forth, and
upon termination of this Agreement for any reason such authorization shall
cease, except to the extent necessary for Distributor to provide maintenance to
its existing Software customers.

          11..2  Confidentiality. Either party acknowledges that by reason of
                 ---------------
its relationship to the other party hereunder it will have access to certain
information and materials concerning the other party's business, plans,
customers, technology, and products that are confidential and of substantial
value to the other party, which value would be impaired if such information were
disclosed to third parties. Either party agrees that it will not use in any way
for its own account or the account of any third party, nor disclose to any third
party, any such confidential information revealed to it by the other party.
Either party shall take every reasonable precaution to protect the
confidentiality of such information. Upon request by a party, the other party
shall advise whether or not it considers any particular information or materials
to be confidential. Distributor shall not publish any technical description of
the Software beyond the description published by Lynx. In the event of
termination of this Agreement, there shall be no use or disclosure by either
party of any confidential information of the other party, and Distributor shall
not manufacture or have manufactured any products utilizing any of Lynx's
confidential information.

     12.  TRADEMARKS AND TRADE NAMES
          --------------------------

          12..1  Use.  During the term of this Agreement, Distributor shall have
                 ---
the right to indicate to the public that it is an authorized distributor of
Lynx's Software and to advertise (within the Territory) such Software under the
trademarks, marks, and trade names that Lynx may adopt from time to time
("Trademarks"). Distributor shall not alter or remove any Trademarks applied at
the factory to the Software Copies, Packages, or other materials contained
therein. Nothing herein shall grant to Distributor any right, title or interest
in the Trademarks. At no time during or after the term of this Agreement shall
Distributor challenge or assist others to challenge the Trademarks or the
registration thereof or attempt to register any trademarks, marks or trade names
confusingly similar to the Trademarks.

          12..2  Approval of Representations. All representations of the
                 ---------------------------
Trademarks that Distributor intends to use shall first be submitted to Lynx for
approval (which shall not be unreasonably withheld) of design, color, and other
details or shall be exact copies of those used by Lynx. If any of the Trademarks
are to be used in conjunction with another trademark on or in relation to the
Software, then Lynx's mark shall be presented equally legibly,

                                      12
<PAGE>

equally prominently, and of greater size than the other but nevertheless
separated from the other so that each appears to be a mark in its own right,
distinct from the other mark.

13.  PATENT, COPYRIGHT, AND TRADEMARK INDEMNITY
     ------------------------------------------

     13..1  Indemnification. Distributor agrees that Lynx has the right to
            ---------------
defend, or at its option to settle, and Lynx agrees, at its own expense, to
defend or at its option to settle, any claim, suit or proceeding brought against
Distributor or its customer on the issue of infringement of any United States
patent, copyright or trademark by the Software Copies distributed hereunder or
the use thereof, subject to the limitations hereinafter set forth. Lynx shall
have sole control of any such action or settlement negotiations, and Lynx agrees
to pay, subject to the limitations hereinafter set forth, any final judgment
entered against Distributor or its customer on such issue in any such suit or
proceeding defended by Lynx. Distributor agrees that Lynx at its sole option
shall be relieved of the foregoing obligations unless Distributor or its
customer notifies Lynx promptly in writing of such claim, suit or proceeding and
gives Lynx authority to proceed as contemplated herein, and, at Lynx's expense,
gives Lynx proper and full information and assistance to settle and/or defend
any such claim, suit or proceeding. If the Software Copies, or any part thereof,
are, or in the opinion of Lynx may become, the subject of any claim, suit or
proceeding for infringement of any United States patent, copyright or trademark,
or if it is adjudicatively determined that the Software Copies, or any part
thereof, infringe any United States patent, copyright or trademark, or if the
distribution or use of the Software Copies, or any part thereof, is, as a
result, enjoined, then Lynx may, at its option and expense: (i) procure for
Distributor and its customers the right under such patent, copyright or
trademark to distribute or use, as appropriate, the Software Copies or such part
thereof; or (ii) replace the Software Copies, or part thereof, with other
suitable Software Copies or parts; or (iii) suitably modify the Software Copies,
or part thereof; or (iv) if the use of the Software Copies, or part thereof, is
prevented by injunction remove the Software Copies, or part thereof, and refund
the aggregate payments paid therefor by Distributor, less a reasonable sum for
use and damage. Lynx shall not be liable for any costs or expenses incurred
without its prior written authorization.

     13..2  Limitation. Notwithstanding the provisions of Subsection 13.1 above,
            ----------
Lynx assumes no liability for (i) any infringement claims with respect to any
product in or with which any of the Software Copies may be used but not covering
the Software Copies standing alone; (ii) any trademark infringements involving
any marking or branding not applied by Lynx or involving any marking or branding
applied at the request of Distributor; or (iii) the modification of the Software
Copies, or any part thereof,

                                       13
<PAGE>

unless such modification was made by Lynx.

     13..3  Entire Liability. THE FOREGOING PROVISIONS OF THIS SECTION 13 STATE
            ----------------
THE ENTIRE LIABILITY AND OBLIGATION OF LYNX AND THE EXCLUSIVE REMEDY OF
DISTRIBUTOR AND ITS CUSTOMERS, WITH RESPECT TO ANY ALLEGED INFRINGEMENT OF
PATENTS, COPYRIGHTS, TRADEMARKS OR OTHER INTELLECTUAL PROPERTY RIGHTS BY THE
SOFTWARE, SOFTWARE COPIES OR ANY PART THEREOF.

     13..4  Notification of Unauthorized Use. Distributor shall promptly notify
            --------------------------------
Lynx in writing upon its discovery of any unauthorized use or infringement of
the Software or Lynx's patent, copyright, trademark or other intellectual
property rights with respect thereto. Lynx shall have the sole and exclusive
right to bring an infringement action or proceeding against a third party, and,
in the event that Lynx brings such an action or proceeding, Distributor shall
cooperate and provide full information and assistance to Lynx and its counsel in
connection with any such action or proceeding.

14.  COMPLIANCE WITH LAWS
     --------------------

     14..1  Foreign Corrupt Practices Act. In conformity with the United States
            -----------------------------

regarding foreign business practices, Distributor and its employees and agents
shall not directly or indirectly make an offer, payment, promise to pay, or

anything of value for the purpose of influencing an act or decision of an

pursuant to Section 9.3 hereof.

                         LYNX Status and Plan (NISSIN)

Overview

        The contract negotiation took longer than planned with the original
     schedule. March '91 was the target month for the contract closing between
     Lynx and NISSIN. This made some impact on our activities such as
     Japanization efforts and staffing activities. However our evaluation of
     the current business position of Lynx in Japan is very positive. We are
     exceeding the forecast level of Jan. '91 significantly.

                      1991 Status (April 1991-March 1992)

Strategy

     1. Closing agreement with Lynx RTS Inc. was top priority strategy.
     2. Positive start up of Lynx business in Japan with strong support of Lynx
        RTS Inc. was a key strategy.
     3. Effective publicity of Lynx products was a key strategy. We performed
        the followings:
        Business Show (May)        [*] attendees
        CIM Show (June)            [*] attendees
        Seminar by Dr. Joseph (Feb.)
        Lynx Seminar (May)
        Seminar by Dr. Joseph (May)
        Lynx Seminar (June)
        UNIX Symposium
           Lecture by Mr. Mitchel Bunnel (July)
        Seminar by Dr. Joseph (Nov.)
     4. The next strategy was to understand the initial market requirements very
        quickly and to lead to the firm business of planned level in the first
        year.
     We have concentrated on;
          The Steel Industry
          The Heavy Industry
          The Measurement and Control Industry
          The Space Industry
          The Electric and Electronic Industry
     5. The strategy on the platform selection was one of key.
        Emphasis was put on;
     (1)68030 as it has big share in Measurement and Control area.
     (2)i386, i486 and PC, W/S using these, as they are widely used.
     (3)Risc machines as they will be promoted in future.
        This will be taken over to 1992.

   Amendment #1 to the International Distributor Agreement # JD9111-01 dated
   ------------
       November 20, 1991 Between Lynx Real Time Systems, Inc. and Nissin
       Software Corporation

Both parties agree that Nissin (Licensee) will use their Source Code Software
licensed under the Source Code Software License Agreement dated June 25, 1993
for customer support. In order to provide quality customer support it is further
agreed that:

     a.   Both parties will mutually study and understand the support
          requirements of customer. Where required, the Licensee can contract to
          support the customer and Lynx (U.S. and Japan) will support the
          Licensee under the then applicable support contract, fees and
          structure.

     b.   Licensee will send to Lynx facilities a minimum of two (2) engineers
          to be trained, by Lynx, on the Licensed Source Code. Additional
          training classes can be scheduled at the then prevailing rates.

     c.   Both parties agree to jointly study customer requests to port LynxOS
          to non-supported platforms. If Lynx does not desire to do the port and
          the Licensee does find it of value to do the port by themselves then
          Licensee will contract with Lynx for the right to complete such
          porting effort. Both parties will further study the possibility to
          remarket the ported Licensed Software to other customers. License fees
          and royalties will be negotiated between Lynx and Licensee.

     d.   Licensee may act as a representative of Lynx in the Licensing of
          Source Code to those customers that desire Source Code under the
          existing terms and conditions of the International Distributor
          Agreement dated November 20, 1991.

     e.   Both parties agree to share information and knowledge acquired in
          paragraphs a, b, c, and d above as long as such information does not
          violate any existing Agreements between Lynx and Licensee, nor
          violates or jeopardizes Lynx's proprietary intellectual property
          rights.

4.   PROGRAM MAINTENANCE AND SUPPORT

     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 [*]
               agreement.

     4.2  Technical Assistance and Training.  Licensor agrees to provide to HP
          ---------------------------------
          such technical assistance and training to HP personnel as may be

     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.   PAYMENT

          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

          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.

          -----
          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.   WARRANTY AND INDEMNIFICATION

     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
                                                                        --------

          ------
          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

7.   TERM AND TERMINATION

     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

          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
          (Warranty and Indemnification), 8 (Limited Liability), 9 (Confidential
          Information) and 10 (Other Provisions).

8.   LIMITED LIABILITY

          IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER FOR LOST
          PROFITS, CONSEQUENTIAL, INCIDENTAL OR SPECIAL DAMAGES ARISING FROM ANY
          CLAIM OR ACTION HEREUNDER, BASED ON CONTRACT, TORT OR OTHER LEGAL
          THEORY, AND WHETHER OR NOT EITHER PARTY HAS BEEN ADVISED OF THE
          POSSIBILITY OF SUCH DAMAGE. IN NO EVENT SHALL EITHER PARTY BE LIABLE
          TO THE OTHER PARTY FOR DAMAGES FOR ANY CAUSE WHATSOEVER IN AN AMOUNT
          IN EXCESS OF THE AMOUNTS PAYABLE TO LICENSOR UNDER THIS AGREEMENT AND
          THE HP/LYNX PRODUCT DEVELOPMENT AGREEMENT. THIS SECTION 8 REPRESENTS
          REASONABLE ALLOCATION OF RISK.

9.   CONFIDENTIAL INFORMATION

     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.  OTHER PROVISIONS

     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

                                       6
<PAGE>

            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
            Agreement.

     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
            --------

  the [*] or any [*] family member that Lynx supports#.

- Provide a LynxOS 3.0.0*functionally equivalent product that supports
  the Intel X86*.

- Support HP-UX version 10.20* as a host for LynxOS 3.0.0* cross development
  targeting the [*] or any [*] family member that Lynx supports#.

- Port the LynxOS SunoS 4.1.x*/5.x* Cross Development Kit (CDK) to HP-UX
  10.20*. The capabilities, features, utilities, and operation on the
  HP/UX should be similar to the SunOS CDK.

- Provide a LynxOS native CDK (Total View and Time Scan) for Intel X86* target
  development.

* 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 and that the improved functionality is
  covered under this Software License Agreement.

# This includes any [*] compliant CPU or CPU core that conforms to the [*]
instruction set architecture. CPU specific differences (i.e. caches, TLB, MMU,
etc.) within a [*] processor family may impact the CPU support portion of the
LynxOS source and/or BSP. If HP selects a [*] CPU not currently supported by
Lynx, HP has the option to perform the porting efforts itself or mutually agree
with Licensor on a business arrangement for the development work to support the
CPU.

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 [*] Support [*] Assistance
----------------------------------------

At HP's option Lynx Real-Time Systems will provide a HP dedicated Lynx [*] at
the Hewlett-Packard Boise site whose responsibilities at a minimum will consist
of:

     .  Support during Custom Board porting efforts
     .  Support during applications porting efforts
     .  Support on Lynx internals questions
     .  Liaison between customer and factory

Qualifications of the dedicated on-site Lynx support engineer will be mutually
agreed to. In order for Lynx to provide this on-site assistance, Hewlett Packard
would need to commit to a minimum of $[*] of support revenue annually to Lynx
for a [*] period. The annual support revenue is calculated by totaling all sums
paid by HP to Lynx for annual support of tools and source code during a HP
fiscal year. Hewlett Packard will provide the necessary on-site facilities
support for this individual including appropriate computing and
telecommunication support.

Maintenance/Support Minimum
---------------------------

In order to keep in force the support and maintenance provided under Exhibit C,
                                                                     ---------
HP must maintain an annual support dollar minimum of $[*]. As an option to this
minimum, HP may enter into a long-term support agreement with Lynx. HP may also
choose not to have Lynx support the programs.

       Hewlett Packard shall provide (i) if possible a sample program separate
       from Hewlett Packard's Product(s), which, when executed in conjunction
       with the Program, clearly illustrates the problem with such Program, and
       (ii) a details description of the problem. Hewlett Packard shall
       prioritize any such problem submitted to Licensor for resolution in
       accordance with the hierarchy described above. Hewlett Packard shall
       supply any additional information reasonably requested by Licensor and
       Hewlett Packard shall make appropriate resources available to assist in
       the problem identification and resolution.

       Acknowledgement Time and Closure Time are measured from the date that
       Licensor receives notice of the error during normal business hours
       (exclusive of Licensor regular holidays) and Hewlett-Packard supplies
       pertinent configuration data and additional information reasonably
       necessary to duplicate the problem, until the correction is received by
       Hewlett-Packard. HP shall receive conformation of receipt of errors
       submitted by HP within 1 working day. Licensor shall communicate to HP
       the status of all unresolved errors on a weekly basis or other frequency
       as mutually agreed to.

       In the event that Licensor does not provide a solution/workaround to a
       "High" or "Critical" error problem within the Closure Time period,
       Licensor shall develop and present a plan to HP within five (5) calendar
       days to provide a solution as soon as reasonably practicable. If this
       plan is unacceptable to HP, HP may choose to escalate discussion of the
       problem with Hewlett-Packard's manager and Licensor CEO.  After such
       discussion, Hewlett-Packard shall provide Licensor with a written summary
       of Hewlett-Packard's position and the results of the discussion,
       detailing the procedure, if any, for preparing and delivering the
       correction.  Hewlett-Packard and Licensor can mutually agree to extend
       the Closure Time on a case-by-case basis.

       Licensor shall advise Hewlett-Packard of its response to, correction of,
       all errors identified in the Software and Documentation, and HP shall
       have the option to incorporate any corrections/workarounds as they become
       available as specified in section 2.6 of this Exhibit C.
