         by the Company at any time at the option of the Company for any
         reason or no reason at all; provided, however, that termination of
         this Agreement shall not impair Employee's right, if any, to

     c.  The Employee will, at the time of separation, receive information
         regarding health insurance continuation and retirement benefits under
         federal law. To the extent that Employee has such rights, nothing in
         this Agreement will impair those rights.

     d.  Except as specifically provided in paragraphs 7(e) and (f), no
         separation pay shall be payable in the event of the termination of
         this Agreement prior to the completion of the term of this Agreement
         and Employee shall only be entitled to his base salary earned prior
         to the date of termination computed pro rata up to and including the
         date of termination and to his accrued vacation as of the effective
         date of termination.

     e.  In the event the Employee is terminated during the term of this
         Agreement without "Good Cause" by the Company the Company will pay
         the Employee a lump sum amount equivalent to twelve (12) months of
         base pay (subject to applicable employment and tax withholdings) and
         the Company will accelerate 50% of unvested stock options under the
         Nokia/Blackbird Acquisition Retention Plan. If Employee elects health
         insurance continuation (COBRA), the Company agrees that it will pay
         the premiums for such coverage for twelve (12) months from the date
         of his separation from the Company. For purposes of this Agreement,
         "Good Cause" for termination shall include: breach of paragraphs 8,
         9, 10 and 11 of this Agreement; willful and serious misconduct in the
         performance of his job responsibilities; conviction of any felony;
         material dishonesty; committing a fraud against the company; engaging
         in conduct demonstrably injurious to and has a material detrimental
         affect on the Company or its business or reputation; breach of
         fiduciary duty; or inability to perform the essential functions of
         his position or any other material breach of any provision of the
         Employment Agreement, which inability to perform or material breach
         is not cured within ten (10) days following written notice from the
         Company.

     f.  Subject to paragraph 7(g) and 7(h), in the event Employee terminates
         this Agreement with Employee's Good Reason, the Company will pay the
         Employee a lump sum amount equivalent to twelve (12) months of base
         pay (subject to applicable employment and tax withholdings) and the
         Company will accelerate 50% of unvested stock options under the
         Nokia/Blackbird Acquisition Retention Plan. Additionally, if Employee
         elects COBRA, the Company agrees that it will pay the premiums for
         such coverage for twelve (12) months from the date of his separation
         from the Company. For purposes of this Agreement, Employee's Good
         Reason is defined as (a) a substantial reduction in Employee's
         function or responsibilities without the Employee's written consent
         or (b) a relocation of Employee's principal place of employment by
         more than 30 miles without the Employee's written consent or (c) a
         reduction of Employee's salary during the term of this Agreement. The
         parties agree that a mere change in job titles shall not constitute a
         substantial reduction in function or responsibilities.

     g.  No separation pay shall be payable under paragraph 7(f) of this
         Agreement if the reduction in Employee's function and
         responsibilities is due to substantial growth of the Company,
         expansion of the Company into additional lines of business or markets
         (including expansion into businesses of any Nokia affiliate), or
         Company consolidations (or reorganizations) of operations, not
         specifically targeted at the Employee, with the operations of any
         present or future parent, affiliate, or subsidiary. Employee shall
         not have the right to terminate this Agreement for Employee's Good
         Reason and the Company shall not be obligated to pay any separation
         pay to Employee under paragraph 7(f) unless:

                                       3
<PAGE>

         (i)   the Employee has provided the Company notice in writing of the
               acts giving rise to the claim of right to termination for
               Employee's Good Reason within thirty (30) days after the
               occurrence of any such acts;

         (ii)  and Employee provides the Company thirty (30) calendar days in
               which to cure the conduct giving rise to the claim of right to
               termination for Employee's Good Reason.

     h.  In the event the Company expressly waives in whole or in part in
         writing the non-compete/non-solicitation provisions in paragraphs
         10(c)(i), (c)(ii), and (c)(iii) the Company's separation payment under
         paragraphs 7(e) and (f) shall be limited to six (6) months of base pay
         and, if the Employee elects COBRA, will pay the premiums for such
         coverage for six (6) months from the date of his separation from the
         Company.

     i.  Paragraphs 8, 9, 10, 11, 12, 13, 18, and 19 of this Agreement will
         survive and continue to be effective notwithstanding the termination of
         this Agreement.

     j.  A termination of this Agreement does not in any way impair the
         Employee's obligations under paragraph 10 of this Agreement unless the
         covenants therein have been waived by the company expressly in writing
         in accordance with the terms of this Agreement.

         employment with the Company, Employee will promptly deliver to the
         Company all documents and materials of any nature pertaining to his
         work with the Company and he will not take with him any documents or
         materials or copies containing any Proprietary Information. At the
         Company's request, Employee will sign necessary confidentiality
         Agreements required in accordance with non-disclosure Agreements
         between the Company and any third-party for the purpose of protecting
         third-party confidential information.

secret information of the Company was used and which was developed entirely on

         Employee shall assign or offer to assign any of his or her rights in
         an invention to his or her employer shall not apply to an invention
         that the Employee developed entirely on his or her own time without

     g.  Notwithstanding paragraph 2, Employee's employment may be terminated
         by the Company at any time at the option of the Company for any
         reason or no reason at all; provided, however, that termination of
         this Agreement shall not impair Employee's right, if any, to
         compensation provided under paragraph 7(e). This Agreement shall
         automatically terminate on the death of Employee.

     h.  Employee may terminate this Agreement at any time upon giving 30 days
         notice in writing to the Company.

     i.  The Employee will, at the time of separation, receive information
         regarding health insurance continuation and retirement benefits under
         federal law. To the extent that Employee has such rights, nothing in
         this Agreement will impair those rights.

     j.  Except as specifically provided in paragraphs 7(e) and (f), no
         separation pay shall be payable in the event of the termination of
         this Agreement prior to the completion of the term of this Agreement
         and Employee shall only be entitled to his base salary earned prior
         to the date of termination computed pro rata up to and including the
         date of termination and to his accrued vacation as of the effective
         date of termination.

     k.  In the event the Employee is terminated during the term of this
         Agreement without "Good Cause" by the Company the Company will pay
         the Employee a lump sum amount equivalent to twelve (12) months of
         base pay (subject to applicable employment and tax withholdings)

                                       14
<PAGE>

         and the Company will accelerate 50% of unvested stock options under
         the Nokia/Blackbird Acquisition Retention Plan. If Employee elects
         health insurance continuation (COBRA), the Company agrees that it
         will pay the premiums for such coverage for twelve (12) months from
         the date of his separation from the Company. For purposes of this
         Agreement, "Good Cause" for termination shall include: breach of
         paragraphs 8, 9, 10 and 11 of this Agreement; willful and serious
         misconduct in the performance of his job responsibilities; conviction
         of any felony; material dishonesty; committing a fraud against the
         company; engaging in conduct demonstrably injurious to and has a
         material detrimental affect on the Company or its business or
         reputation; breach of fiduciary duty; or inability to perform the
         essential functions of his position or any other material breach of
         any provision of the Employment Agreement, which inability to perform
         or material breach is not cured within ten (10) days following
         written notice from the Company.

     l.  Subject to paragraph 7(g) and 7(h), in the event Employee terminates
         this Agreement with Employee's Good Reason, the Company will pay the
         Employee a lump sum amount equivalent to twelve (12) months of base
         pay (subject to applicable employment and tax withholdings) and the
         Company will accelerate 50% of unvested stock options under the
         Nokia/Blackbird Acquisition Retention Plan. Additionally, if Employee
         elects COBRA, the Company agrees that it will pay the premiums for
         such coverage for twelve (12) months from the date of his separation
         from the Company. For purposes of this Agreement, Employee's Good
         Reason is defined as (a) a substantial reduction in Employee's
         function or responsibilities without the Employee's written consent;
         provided however, the parties agree that a mere change in job titles
         shall not constitute a substantial reduction in function or
         responsibilities, or (b) a relocation of Employee's principal place
         of employment by more than 30 miles without the Employee's written
         consent or (c) a reduction of Employee's salary during the term of
         this Agreement.

     g.  No separation pay shall be payable under paragraph 7(f) of this
         Agreement if the reduction in Employee's function and
         responsibilities is due to substantial growth of the Company,
         expansion of the Company into additional lines of business or markets
         (including expansion into businesses of any Nokia affiliate), or
         Company consolidations (or reorganizations) of operations, not
         specifically targeted at the Employee, with the operations of any
         present or future parent, affiliate, or subsidiary. Employee shall
         not have the right to terminate this Agreement for Employee's Good
         Reason and the Company shall not be obligated to pay any separation
         pay to Employee under paragraph 7(f) unless:

         (i)   the Employee has provided the Company notice in writing of the
               acts giving rise to the claim of right to termination for
               Employee's Good Reason within thirty (30) days after the
               occurrence of any such acts;

         (ii)  and Employee provides the Company thirty (30) calendar days in
               which to cure the conduct giving rise to the claim of right to
               termination for Employee's Good Reason.

     h.  In the event the Company expressly waives in whole or in part in
         writing the non-compete/non-solicitation provisions in paragraphs
         10(c)(i), (c)(ii), and (c)(iii) the Company's separation payment under
         paragraphs 7(e) and (f) shall be limited to six (6) months of base pay
         and, if the Employee elects COBRA, will pay the premiums for such
         coverage for six (6) months from the date of his separation from the
         Company.

                                       15
<PAGE>

     i.  Paragraphs 8, 9, 10, 11, 12, 13, 18, and 19 of this Agreement will
         survive and continue to be effective notwithstanding the termination of
         this Agreement.

     j.  A termination of this Agreement does not in any way impair the
         Employee's obligations under paragraph 10 of this Agreement unless the
         covenants therein have been waived by the company expressly in writing
         in accordance with the terms of this Agreement.

8.   Proprietary Information & Confidentiality
     -----------------------------------------

     a.  Employee understands that his employment with the Company creates a
         relationship of confidence and trust with respect to any information
         of a confidential or secret nature that he has acquired or will
         acquire as a result of his employment with the Company that relates
         to the business of the Company or to the business of any parent,
         subsidiary, affiliate, customer or supplier of the Company or any
         other party with whom the Company agrees to hold information of such
         party in confidence ("Proprietary Information"). Such Proprietary
         Information includes but is not limited to inventions, trade secrets,

     b.  At all times, both during his employment and after its termination,
         Employee will keep and hold all Proprietary Information in strict
         confidence and trust, and he will not use or disclose any Proprietary
         Information without the prior written consent of the Company, except
         as may be necessary to perform his duties as an Employee of the
         Company for the benefit of the Company. Upon termination of his
         employment with the Company, Employee will promptly deliver to the

     ------------------------

     a.  Employee agrees that all inventions, discoveries, developments,
         improvements, trademarks, copyrights, trade secrets, innovations,
         mask works, ideas, contributions, and any other intellectual property
         of any kind (herein called collectively "Inventions"), whether or not
         patented or patentable, or otherwise protectable in law, which are
         conceived, made, developed or acquired by Employee, either

         Company his entire right, title, and interest in and to the
         Inventions. Employee further agrees to promptly and fully disclose

         lawful applications, assignments, and other documents which the
         Company requests for protecting the Inventions in the United States,
         Canada or any other country. The Company shall have the full and sole
         power to prosecute such applications and to take all other action

         employment by the Company and which relate to the business of the
         Company. The Company shall have the full right to seek and procure
         copyright on the Creations, and Employee shall co-operate fully, at
         the expense of the Company, in securing copyrights and in any legal
         actions and proceedings concerning the Creations.

         be obligated to assign under Section 2870 of the California Labor

         determined to be subject to Section 2870, the Company shall promptly
         return to Employee all copies of any medium containing information by
         Employee pursuant to this provision. Employee shall, as a condition
         of this Agreement, sign Exhibits A and B to this Agreement
         concurrently with the execution of this Agreement.

12.  Remedies

     d.  Upon a breach by Employee as determined by a court of competent
         jurisdiction of any of the covenants contained in this agreement, the
         Company shall suffer losses for which an award of damages does not
         provide an adequate remedy and shall be entitled to have a court of
         competent jurisdiction enter an injunction against Employee
         prohibiting any further breach of the covenants contained herein. The
         parties agree that the services to be performed are of a unique,

                      WRITTEN NOTIFICATION TO EMPLOYEE

     In accordance with Section 2872 of the California Labor Code, you are
hereby notified that this Agreement does not require you to assign to the
Company any invention for which no equipment, supplies, facility, or trade
secret information of the Company was used and which was developed entirely on
your own time, and (a) which does not relate (1) to the business of the Company
or (2) to the Company's actual or demonstrably anticipated research or
development, or (b) which does not result from any work performed by you for the
Company.

     You are hereby provided a copy of Section 2870 of the California Labor
Code:

                  SECTION 2870 OF THE CALIFORNIA LABOR CODE

          "(a) Any provision in an employment agreement which provides that an
          Employee shall assign or offer to assign any of his or her rights in
          an invention to his or her employer shall not apply to an invention
          that the Employee developed entirely on his or her own time without
          using the employer's equipment, supplies, facilities, or trade secret
          information except for those inventions that either:

               (3)    Relate at the time of conception or reduction to
                      practice of the invention to the employer's business, or
                      actual or demonstrably anticipated research or
                      development of the employer.

               (4)    Result from any work performed by the Employee for the
                      employer.

          (b) To the extent a provision in an employment agreement purports to
          require an Employee to assign an invention otherwise excluded from
          being required to be assigned under subdivision (a), the provision is
          against the public policy of this state and is unenforceable."

     I hereby acknowledge receipt of this written notification.

         Reason is defined as (a) a substantial reduction in Employee's
         function or responsibilities without the Employee's written consent;

         of employment by more than 30 miles without the Employee's written
         consent or (c) a reduction of Employee's salary during the term of

     g.  No separation pay shall be payable under paragraph 7(f) of this
         Agreement if the reduction in Employee's function and
         responsibilities is due to substantial growth of the Company,
         expansion of the Company into additional lines of business or markets
         (including expansion into businesses of any Nokia affiliate), or
         Company consolidations (or reorganizations) of operations, not
         specifically targeted at the Employee, with the operations of any
         present or future parent, affiliate, or subsidiary. Employee shall
         not have the right to terminate this Agreement for Employee's Good
         Reason and the Company shall not be obligated to pay any separation
         pay to Employee under paragraph 7(f) unless:

         (i)   the Employee has provided the Company notice in writing of the
               acts giving rise to the claim of right to termination for
               Employee's Good Reason within thirty (30) days after the
               occurrence of any such acts;

         (ii)  and Employee provides the Company thirty (30) calendar days in
               which to cure the conduct giving rise to the claim of right to

         writing the non-compete/non-solicitation provisions in paragraphs

         paragraphs 7(e) and (f) shall be limited to six (6) months of base pay
         and, if the Employee elects COBRA, will pay the premiums for such
         coverage for six (6) months from the date of his separation from the
         Company.

     i.  Paragraphs 8, 9, 10, 11, 12, 13, 18, and 19 of this Agreement will
         survive and continue to be effective notwithstanding the termination of
         this Agreement.

                                       27

     j.  A termination of this Agreement does not in any way impair the
         Employee's obligations under paragraph 10 of this Agreement unless the
         covenants therein have been waived by the company expressly in writing
         in accordance with the terms of this Agreement.

hereby notified that this Agreement does not require you to assign to the
Company any invention for which no equipment, supplies, facility, or trade
secret information of the Company was used and which was developed entirely on

or (2) to the Company's actual or demonstrably anticipated research or

          Employee shall assign or offer to assign any of his or her rights in
          an invention to his or her employer shall not apply to an invention
          that the Employee developed entirely on his or her own time without
          using the employer's equipment, supplies, facilities, or trade secret
          information except for those inventions that either:

    s.  Notwithstanding paragraph 2, Employee's employment may be terminated by
        the Company at any time at the option of the Company for any reason or
        no reason at all; provided, however, that termination of this Agreement
        shall not impair Employee's right, if any, to compensation provided
        under paragraph 7(e). This Agreement shall automatically terminate on
        the death of Employee.

    t.  Employee may terminate this Agreement at any time upon giving 30 days
        notice in writing to the Company.

    u.  The Employee will, at the time of separation, receive information
        regarding health insurance continuation and retirement benefits under
        federal law. To the extent that Employee has such rights, nothing in
        this Agreement will impair those rights.

    v.  Except as specifically provided in paragraphs 7(e) and (f), no
        separation pay shall be payable in the event of the termination of this
        Agreement prior to the completion of the term of this Agreement and
        Employee shall only be entitled to his base salary earned prior to the
        date of termination computed pro rata up to and including the date of
        termination and to his accrued vacation as of the effective date of
        termination.

    w.  In the event the Employee is terminated during the term of this
        Agreement without "Good Cause" by the Company the Company will pay the
        Employee a lump sum amount equivalent to twelve (12) months of base pay
        (subject to applicable employment and tax withholdings) and the Company
        will accelerate 50% of unvested stock options under the Nokia/Blackbird
        Acquisition Retention Plan. If Employee elects health insurance
        continuation (COBRA), the

                                       38
<PAGE>

        Company agrees that it will pay the premiums for such coverage for
        twelve (12) months from the date of his separation from the Company. For
        purposes of this Agreement, "Good Cause" for termination shall include:
        breach of paragraphs 8, 9, 10 and 11 of this Agreement; willful and
        serious misconduct in the performance of his job responsibilities;
        conviction of any felony; material dishonesty; committing a fraud
        against the company; engaging in conduct demonstrably injurious to and
        has a material detrimental affect on the Company or its business or
        reputation; breach of fiduciary duty; or inability to perform the
        essential functions of his position or any other material breach of any
        provision of the Employment Agreement, which inability to perform or
        material breach is not cured within ten (10) days following written
        notice from the Company.

    x.  Subject to paragraph 7(g) and 7(h), in the event Employee terminates
        this Agreement with Employee's Good Reason, the Company will pay the
        Employee a lump sum amount equivalent to twelve (12) months of base pay
        (subject to applicable employment and tax withholdings) and the Company
        will accelerate 50% of unvested stock options under the Nokia/Blackbird
        Acquisition Retention Plan. Additionally, if Employee elects COBRA, the
        Company agrees that it will pay the premiums for such coverage for
        twelve (12) months from the date of his separation from the Company. For
        purposes of this Agreement, Employee's Good Reason is defined as (a) a
        substantial reduction in Employee's function or responsibilities without
        the Employee's written consent; provided however, the parties agree that
        a mere change in job titles shall not constitute a substantial reduction
        in function or responsibilities, or (b) a relocation of Employee's
        principal place of employment by more than 30 miles without the
        Employee's written consent or (c) a reduction of Employee's salary
        during the term of this Agreement.

    g.  No separation pay shall be payable under paragraph 7(f) of this
        Agreement if the reduction in Employee's function and responsibilities
        is due to substantial growth of the Company, expansion of the Company
        into additional lines of business or markets (including expansion into
        businesses of any Nokia affiliate), or Company consolidations (or
        reorganizations) of operations, not specifically targeted at the
        Employee, with the operations of any present or future parent,
        affiliate, or subsidiary. Employee shall not have the right to terminate
        this Agreement for Employee's Good Reason and the Company shall not be
        obligated to pay any separation pay to Employee under paragraph 7(f)
        unless:

        (i)  the Employee has provided the Company notice in writing of the
             acts giving rise to the claim of right to termination for
             Employee's Good Reason within thirty (30) days after the occurrence
             of any such acts;

        (ii) and Employee provides the Company thirty (30) calendar days in
             which to cure the conduct giving rise to the claim of right to
             termination for Employee's Good Reason.

    h.  In the event the Company expressly waives in whole or in part in
        writing the non-compete/non-solicitation provisions in paragraphs
        10(c)(i), (c)(ii), and (c)(iii) the Company's separation payment under
        paragraphs 7(e) and (f) shall be limited to six (6) months of base pay
        and, if the Employee elects COBRA, will pay the premiums for such
        coverage for six (6) months from the date of his separation from the
        Company.

                                       39
<PAGE>

    i.  Paragraphs 8, 9, 10, 11, 12, 13, 18, and 19 of this Agreement will
        survive and continue to be effective notwithstanding the termination of
        this Agreement.

    j.  A termination of this Agreement does not in any way impair the
        Employee's obligations under paragraph 10 of this Agreement unless the
        covenants therein have been waived by the company expressly in writing
        in accordance with the terms of this Agreement.


8.   Proprietary Information & Confidentiality
     -----------------------------------------

     a.  Employee understands that his employment with the Company creates a
         relationship of confidence and trust with respect to any information of
         a confidential or secret nature that he has acquired or will acquire as
         a result of his employment with the Company that relates to the
         business of the Company or to the business of any parent, subsidiary,
         affiliate, customer or supplier of the Company or any other party with
         whom the Company agrees to hold information of such party in confidence
         ("Proprietary Information"). Such Proprietary Information includes but
         is not limited to inventions, trade secrets, product specifications,
         inventions, designs, sketches, graphs, drawings, systems, computer
         software and programs, current and planned research and development,
         customer requirements, marketing plans, product plans, business
         strategies, financial information, forecasts, and customer lists.

     b.  At all times, both during his employment and after its termination,
         Employee will keep and hold all Proprietary Information in strict
         confidence and trust, and he will not use or disclose any Proprietary
         Information without the prior written consent of the Company, except as
         may be necessary to perform his duties as an Employee of the Company
         for the benefit of the Company. Upon termination of his employment with
         the Company, Employee will promptly deliver to the Company all
         documents and materials of any nature pertaining to his work with the
         Company and he will not take with him any documents or materials or
         copies containing any Proprietary Information. At the Company's
         request, Employee will sign necessary confidentiality Agreements
         required in accordance with non-disclosure Agreements between the
         Company and any third-party for the purpose of protecting third-party
         confidential information.

     c.  It shall not be a violation of this Agreement for Employee, after the
         termination of employment with the Company, to use or disclose
         information which is generally known to the public at the time of
         disclosure or later becomes so generally known through no fault of the
         Employee. The burden of showing that information is generally known to
         the public shall rest with the Employee. Nothing in this provision,
         however, shall be construed to affect the rights and obligations
         contained in paragraph 10 of this Agreement.

9.   No Breach of Prior Agreement
     ----------------------------

     Employee represents that his performance of all the terms of this Agreement
and his duties as an Employee of the Company will not breach any invention
assignment, proprietary information or similar Agreement with any former
employer or other party.  Employee also represents that he will not use in the
performance of his duties for the Company any documents or materials of a former
employer that are not generally available to the public or have not been legally
transferred to the Company.

                way impair or limit the restrictions set forth in paragraph
                10(c)(iv) of this Agreement.

         (ix)   Paragraphs 10(c)(i), 10(c)(ii), and 10(c)(iii) do not restrict
                Employee from accepting employment with a Competitor if the

                Company informing it of the Competitor with whom he has accepted
                employment and such notice shall specify the duties to be

         engaged in such business, or if the Employee, directly or indirectly,
         performs such services for such person or if the Employee or any member
         of the Employee's Immediate Family beneficially owns any equity
         interest in or securities of, or any interest or securities convertible
         into any equity interest in or securities of, any such person;
         provided, however, that the ownership of publicly traded securities
         having no more than three percent of the outstanding voting power of
         any Competitor of the Company or any of their respective affiliates or
         an investment of no more than 3% of any venture fund, shall be deemed
         not to be a violation of this Agreement so long as the Employee or such
         member of Employee's Immediate Family has no other connection or
         relationship with such Competitor or such venture fund.  For purposes
         of this paragraph, Immediate Family is defined as the spouse and minor
         children of the Employee.

     k.  Waiver of  Non-Compete Obligations
         ----------------------------------

         The Company has the right to waive, in whole on in part, the
         restrictions set forth in paragraph 10. In order for a waiver of such

         ------------

         the terms of this Agreement and his responsibilities under it.

     a.  Employee agrees that all inventions, discoveries, developments,
         improvements, trademarks, copyrights, trade secrets, innovations, mask
         works, ideas, contributions, and any other intellectual property of any
         kind (herein called collectively "Inventions"), whether or not patented
         or patentable, or otherwise protectable in law,

                                       42
<PAGE>

         which are conceived, made, developed or acquired by Employee, either
         individually or jointly, during his employment with the Company
         (including employment with Company before and after the execution of
         this Agreement) and which relate in any manner to Employee's work, the
         research or business of the Company, or fields to which the business of
         the Company may reasonably extend, shall belong to the Company.
         Employee agrees to irrevocably assign and transfer to the Company his
         entire right, title, and interest in and to the Inventions. Employee
         further agrees to promptly and fully disclose the Inventions to the
         Company, in writing if requested by the Company, and to execute and
         deliver or otherwise assist any and all lawful applications,
         assignments, and other documents which the Company requests for
         protecting the Inventions in the United States, Canada or any other
         country. The Company shall have the full and sole power to prosecute
         such applications and to take all other action concerning the
         Inventions, and Employee agrees to co-operate fully, at the expense of
         the Company, in the preparation and prosecution of all such
         applications and in any legal actions and proceedings concerning the
         Inventions.

     b.  Employee agrees to and does assign, convey, and transfer to the
         Company any and all manuscripts, programs, writings, pictorial
         materials, and other creations (called collectively "Creations"),
         created by Employee, either individually or jointly, during his
         employment by the Company and which relate to the business of the
         Company. The Company shall have the full right to seek and procure
         copyright on the Creations, and Employee shall co-operate fully, at the
         expense of the Company, in securing copyrights and in any legal actions
         and proceedings concerning the Creations.

     c.  Paragraph 11 shall not apply to inventions which an Employee cannot be
         obligated to assign under Section 2870 of the California Labor Code
         (hereinafter called "Section 2870"). Whether or not Employee believes
         any invention is protected by Section 2870, Employee shall disclose
         such invention to the Company in order to permit the Company to
         determine such issues that may arise. The Company shall not disclose
         information about such invention to any third party, and shall use such
         information only for purposes of evaluating its rights under this
         Employment Agreement. In the event such invention is determined to be
         subject to Section 2870, the Company shall promptly return to Employee
         all copies of any medium containing information by Employee pursuant to
         this provision. Employee shall, as a condition of this Agreement, sign
         Exhibits A and B to this Agreement concurrently with the execution of
         this Agreement.

12.  Remedies
     --------

     j.  Upon a breach by Employee as determined by a court of competent
         jurisdiction of any of the covenants contained in this agreement, the
         Company shall suffer losses for which an award of damages does not
         provide an adequate remedy and shall be entitled to have a court of
         competent jurisdiction enter an injunction against Employee prohibiting
         any further breach of the covenants contained herein. The parties agree
         that the services to be performed are of a unique, special, and
         extraordinary character. Therefore, in the event of any controversy

         remedy, however, shall be nonexclusive and shall be in addition to any
         other remedies which the Company may have.

by the Company is fair and reasonable and further acknowledges the importance to
the Company of the Company's proprietary information and particular methods of
doing business, the post-employment restrictions on Employee's activities are
likewise fair and reasonable.  Employee acknowledges that he has had the
opportunity to review this agreement with his own counsel and agrees to its
terms and conditions freely and voluntarily. Employee further acknowledges that
nothing in this agreement alters the "at will" nature of the employment
relationship, except that the at will employment relationship does not impair
Employee's right to compensation, if any, under paragraph 7 of this Agreement.

The parties have executed this Agreement on the date as indicated.

     In accordance with Section 2872 of the California Labor Code, you are
hereby notified that this Agreement does not require you to assign to the
Company any invention for which no equipment, supplies, facility, or trade
secret information of the Company was used and which was developed entirely on
your own time, and (a) which does not relate (1) to the business of the Company
or (2) to the Company's actual or demonstrably anticipated research or
development, or (b) which does not result from any work performed by you for the
Company.

     You are hereby provided a copy of Section 2870 of the California Labor
Code:

               SECTION 2870 OF THE CALIFORNIA LABOR CODE
          "(a) Any provision in an employment agreement which provides that an
          Employee shall assign or offer to assign any of his or her rights in
          an invention to his or her employer shall not apply to an invention
          that the Employee developed entirely on his or her own time without
          using the employer's equipment, supplies, facilities, or trade secret
          information except for those inventions that either:

               (7)  Relate at the time of conception or reduction to practice
                    of the invention to the employer's business, or actual or

          require an Employee to assign an invention otherwise excluded from
          being required to be assigned under subdivision (a), the provision is
          against the public policy of this state and is unenforceable."

         (subject to applicable employment and tax withholdings) and the Company

         Company agrees that it will pay the premiums for such coverage for

         relocation of Employee's principal place of employment by more than 30
         miles without the Employee's written consent or (c) a reduction of

     g.  No separation pay shall be payable under paragraph 7(f) of this
         Agreement if the reduction in Employee's function and responsibilities
         is due to substantial growth of the Company, expansion of the Company
         into additional lines of business or markets (including expansion into
         businesses of any Nokia affiliate), or Company consolidations (or
         reorganizations) of operations, not specifically targeted at the
         Employee, with the operations of any present or future parent,
         affiliate, or subsidiary. Employee shall not have the right to
         terminate this Agreement for Employee's Good Reason and the Company
         shall not be obligated to pay any separation pay to Employee under
         paragraph 7(f) unless:

         (i)  the Employee has provided the Company notice in writing of the
              acts giving rise to the claim of right to termination for
              Employee's Good Reason within thirty (30) days after the
              occurrence of any such acts;

                                       51

         (ii) and Employee provides the Company thirty (30) calendar days in
              which to cure the conduct giving rise to the claim of right to
              termination for Employee's Good Reason.

     h.  In the event the Company expressly waives in whole or in part in
         writing the non-compete/non-solicitation provisions in paragraphs
         10(c)(i), (c)(ii), and (c)(iii) the Company's separation payment under
         paragraphs 7(e) and (f) shall be limited to six (6) months of base pay
         and, if the Employee elects COBRA, will pay the premiums for such
         coverage for six (6) months from the date of his separation from the
         Company.

     i.  Paragraphs 8, 9, 10, 11, 12, 13, 18, and 19 of this Agreement will
         survive and continue to be effective notwithstanding the termination of
         this Agreement.

     j.  A termination of this Agreement does not in any way impair the
         Employee's obligations under paragraph 10 of this Agreement unless the
         covenants therein have been waived by the company expressly in writing
         in accordance with the terms of this Agreement.

         Information without the prior written consent of the Company, except as
         may be necessary to perform his duties as an Employee of the Company
         for the benefit of the Company. Upon termination of his employment with
         the Company, Employee will promptly deliver to the Company all
         documents and materials of any nature pertaining to his work with the
         Company and he will not take with him any documents or materials or

         Employee. The burden of showing that information is generally known to
         the public shall rest with the Employee. Nothing in this provision,

         obligated to assign under Section 2870 of the California Labor Code

         provide an adequate remedy and shall be entitled to have a court of

17.  Invalidity of Any Provision
     ---------------------------

     The validity, legality or enforceability of the remainder of this Agreement
will not be affected even if one or more of the provisions of this Agreement
will be held to be invalid, illegal or unenforceable in any respect.  Further,

prescribed activities covered by paragraph 10 of this Agreement should be deemed
unenforceable, then this Agreement shall be construed to cover the maximum
period of time, geographic area and scope of prescribed activities (not to
exceed the maximum time, geographic area or scope set forth herein) as may be
valid under applicable law and each of the parties hereto shall request any
court considering the enforceability of this Agreement to construe and/or reform
it so as to render it enforceable to the maximum extent as provided above.

18.  Applicable Law
     --------------

     This Agreement shall be interpreted and enforced in accordance with the
laws of the State of California.  The parties agree that the paragraph 10 of
this Agreement relating to Employee's non-compete/non-solicitation covenants
have arisen out of sale of the business (including goodwill) and corporate
shares.  Additionally, Employee specifically acknowledges that he is a key
employee and substantial shareholder of the Company and that the Agreement and
Plan of Merger will result in the purchase of all of the Company's shares
possessed by him subject to such terms and conditions set forth in the Agreement
and Plan of Merger.

19.  Reasonableness of Restrictions and At-Will Employment
     -----------------------------------------------------

     Employee has read this agreement and agrees that the consideration provided
by the Company is fair and reasonable and further acknowledges the importance to
the Company of the Company's proprietary information and particular methods of
doing business, the post-employment restrictions on Employee's activities are
likewise fair and reasonable.  Employee acknowledges that he has had the
opportunity to review this agreement with his own counsel and agrees to its
terms and conditions freely and voluntarily. Employee further acknowledges that
nothing in this agreement alters the "at will" nature of the employment
relationship, except that the at will employment relationship does not impair
Employee's right to compensation, if any, under paragraph 7 of this Agreement.

The parties have executed this Agreement on the date as indicated.

                       WRITTEN NOTIFICATION TO EMPLOYEE

     In accordance with Section 2872 of the California Labor Code, you are
hereby notified that this Agreement does not require you to assign to the
Company any invention for which no equipment, supplies, facility, or trade
secret information of the Company was used and which was developed entirely on
your own time, and (a) which does not relate (1) to the business of the Company
or (2) to the Company's actual or demonstrably anticipated research or
development, or (b) which does not result from any work performed by you for the
Company.

     You are hereby provided a copy of Section 2870 of the California Labor
Code:

               SECTION 2870 OF THE CALIFORNIA LABOR CODE
          "(a) Any provision in an employment agreement which provides that an
          Employee shall assign or offer to assign any of his or her rights in
          an invention to his or her employer shall not apply to an invention
          that the Employee developed entirely on his or her own time without
          using the employer's equipment, supplies, facilities, or trade secret
          information except for those inventions that either:

               (9)  Relate at the time of conception or reduction to practice
                    of the invention to the employer's business, or actual or
                    demonstrably anticipated research or development of the
                    employer.

               (10) Result from any work performed by the Employee for the
                    employer.

          (b) To the extent a provision in an employment agreement purports to
          require an Employee to assign an invention otherwise excluded from
          being required to be assigned under subdivision (a), the provision is
          against the public policy of this state and is unenforceable."

     I hereby acknowledge receipt of this written notification.
