                                   ARTICLE III
                          ELIGIBILITY FOR PARTICIPATION

Participants are those salaried employees of the Company selected based on
recommendations by the Supervisors, with the endorsement of the applicable
Managers. The Committee may authorize the Company's Vice President of Human
Resources to determine who shall participate in the Plan, except for members of
the Section 16 Group. Participation of members of the Section 16 Group shall
require Committee approval. The selection of an employee as a Participant for a
Plan Year may be shown by the Committee's establishment of a bonus pool for such
Plan Year that includes a target award for such employee. No member of the
Committee shall be eligible to participate in the Plan.


                                   ARTICLE IV
                                   BONUS POOL

1.   As  early as  feasible  at the  beginning  of each  Plan  Year,  the  Chief
     Executive  Officer  shall  recommend  to the  Committee  for its review and
     approval an amount to be established as a bonus pool for the Plan Year. The
     proposed pool amount shall be calculated as the sum of (a) the target bonus
     awards  (calculated  in  accordance  with  Exhibit A hereto) for  employees
     recommended  to be  Participants  for the Plan Year and (b) an  estimate of
     target  awards for  positions  that may be filled during the Plan Year (new
     hires who may become Participants on a pro rata basis).

2.   To assist the Committee in making a determination with respect to the Chief
     Executive Officer's  recommendation,  the proposed bonus pool shall also be
     expressed  as a  percentage  of EBIT,  as set forth in the  Business  Plan.
     However,  for  this  purpose  such  EBIT  shall  be  computed  prior to the
     deduction of incentive  compensation payments to be paid under the Plan and
     may exclude anticipated extraordinary items.

3.   Incentive  compensation payments will be made in accordance with Article V.
     In accordance with Exhibit A hereto, the aggregate  incentive  compensation
     payments made under the Plan for the Plan Year may exceed the bonus pool in
     certain  circumstances,  but  in no  event  will  the  aggregate  incentive
     compensation  payments  under the Plan for a Plan Year  exceed  205% of the
     bonus pool established for that Plan Year.

4.   The bonus pool does not represent a segregated fund of assets. Participants
     have no claim on any particular  group of Company assets,  either before or
     after incentive  compensation payments are determined or authorized for the
     Plan Year. Any incentive  compensation  awarded under the Plan will be paid
     from the general assets of the Company.





                                    ARTICLE V
                         INCENTIVE COMPENSATION PAYMENTS

1.   CALCULATION  AND  AUTHORIZATION  OF  PAYMENTS  --  Incentive   compensation
     payments to Participants shall be calculated,  under the supervision of the
     Chief Financial Officer,  in accordance with the formula and procedures set
     forth in Exhibit A hereto and the aggregate of all Participant's  incentive
     awards  determined under Exhibit A will be recommended to the Committee for
     its consideration.  Information  regarding the proposed incentive award for
     each  Particpant  who is a member of the Section 16 Group will be presented
     separately. The individual calculations for other Participants will also be
     available for the  Committee's  review.  No award is payable under the Plan
     for any Plan Year unless and until the Committee  authorizes the awards for
     Participants  generally and for Participants who are members of the Section
     16 Group in particular.

2.   INDIVIDUAL  PERFORMANCE  FACTORS - A Participant's  Individual  Performance
     Factor that is factored into the  incentive  payment  calculation  shall be
     based on  achievement  of  performance  goals,  as provided in Exhibit A. A
     Participant's  Individual  Performance  Factor shall be  determined  by the
     Participant's  Supervisor.  The Individual  Performance Factor of the Chief
     Executive  Officer  shall be  determined by the Committee and the Committee
     shall review the Individual  Performance  Factors of other Participants who
     are members of the Section 16 Group.  The Committee  may, at the request of
     any member of the Committee,  review the Individual  Performance Factors of
     any other  Participant  or groups of  Participants.  The Committee may make
     adjustments in any such performance factors as it considers appropriate.

3.   ORGANIZATIONAL  PERFORMANCE  FACTORS - After the end of the Plan Year,  the
     performance  of the Company and each  Business  Unit shall be rated against
     the Business Plan to determine the Organizational  Performance Factors that
     are factored into the  incentive  payment  calculation,  all as provided in
     Exhibit A hereto.

4.   METHOD OF PAYMENT -

     A.   The incentive  compensation  payment  authorized for each  Participant
          with  respect to each Plan Year shall be paid to such  Participant  in
          cash within two and one-half  months after the close of the Plan Year,
          provided  however,  that payments will not be made until the Company's
          registered  independent  public  accountant has completed its audit of
          the Company's financial statements for the Plan Year.  Notwithstanding
          any  awards  authorized  by the  Committee  for  the  Plan  Year,  the
          Committee may, in its sole  discretion,  cancel or adjust downward the
          unpaid awards for any or all Participants  based on the results of the
          audit.

     B.   All Incentive compensation payments shall be made in cash and paid net
          of any taxes or other amounts required to be withheld.

5.   RIGHTS OF PARTICIPANTS

     A.   Selection of an individual as a Participant for one Plan Year does not
          mean that the individual will be selected to participate in future
          Plan Years.

     B.   The establishment of a bonus pool is subject to the discretion of the
          Committee. No Participant shall have any right to require the
          Committee to establish a bonus pool for any Plan Year. No Participant
          shall have any vested interest or property right or any share in any
          amounts that may be established as a bonus pool.

     C.   All payments are subject to the discretion of the Committee. No
          Participant shall have any right to require the Committee to authorize
          any incentive compensation payments under the Plan. Even though
          Participant performance may be rated periodically during the Plan Year
          and progress against Organizational Performance Factors may be
          tracked, all incentive compensation payments are subject to
          calculation as set forth in Exhibit A and the discretion of the
          Committee. The mere existence of periodic performance assessments or
          organizational performance tracking does not give





          the Participant any basis for claiming any incentive compensation
          under this Plan on a pro rata basis during the Plan Year or otherwise.

     D.   Payments properly made under the Plan and distributed to Participants
          shall not be recoverable from the Participant by the Company.

     E.   Nothing in this Plan gives a Participant the right to remain in the
          employ of the Company. Except to the extent explicitly provided
          otherwise in a then effective written employment contract executed by
          Participant and the Company, Participant is an at will employee whose
          employment may be terminated without liability at any time for any
          reason.


                                   ARTICLE VI
                                 ADMINISTRATION

The Plan  shall be  administered  under  the  direction  of the  Committee.  The
Committee  shall have the right to construe the Plan, to interpret any provision
of the  Plan,  to make  rules  and  regulations  relating  to the  Plan,  and to
determine any factual  question  arising in connection with the Plan's operation
after such  investigation or hearing as the Committee may deem appropriate.  Any
decision  made by the  Committee  under the  provisions of this Article shall be
conclusive and binding on all parties  concerned.  The Committee may delegate to
the officers or  employees  of the Company the  authority to execute and deliver
those  instruments  and  documents,  to do all acts and things,  and to take all
other  steps  deemed  necessary,  advisable  or  convenient  for  the  effective
administration  of this Plan in accordance  with its terms and purpose.  For the
avoidance of doubt, the Committee may not delegate the duty to approve the bonus
pool under Article IV or to authorize awards under Article V.


                                   ARTICLE VII
                        AMENDMENT OR TERMINATION OF PLAN

The Board shall have the unilateral right to terminate or amend this Plan at any
time with respect to all or some  Participants  with respect to any unpaid bonus
amounts, and to discontinue the establishment of bonus pools.


                                  ARTICLE VIII
                                 EFFECTIVE DATE

This Amended and Restated Plan shall be effective  beginning  with the Company's
2007 fiscal year.





                                    EXHIBIT A
              CALCULATION OF CASH BONUS INCENTIVE PROGRAM PAYMENTS


A.   AWARD FORMULA

     1.   It is expected that the business and individual objectives established
          for this Plan will be accomplished in accordance with the Company's
          Code of Conduct. A Participant's commitment and adherence to the
          Company's ethical standards will be considered in determining awards
          under this Plan.

     2.   Incentive compensation payments will be calculated by multiplying the
          Participant's Annual Salary by the applicable "Target Level" for the
          Participant (as defined in B) to establish the Participant's "Target
          Award"

     3.   Subject to any discretionary adjustments made pursuant to the Plan and
          to any limitations contained in the Plan, awards for Participants who
          are members of a Business Unit will be determined by mutliplying the
          Participant's Target Award by the sum of -

               a.   30% of the Individual Performance Factor (as defined in C);

               b.   50% of the relevant  Business  Unit  Performance  Factor (as
                    defined in D); and

               c.   20% of the Corporate Performance Factor (as defined in D).

     4.   Subject to any discretionary adjustments made pursuant to the Plan and
          to any limitations contained in Plan, awards for Participants other
          than the Chief Executive Officer who are members of a corporate
          functional group rather than a Business Unit will determined by
          multiplying the Participant's Target Award by the sum of

               a.   30% of the Individual  Performance Factor (as defined in C);
                    and

               b.   70% of the Corporate Performance Factor (as defined in D).

     5.   Subject to any discretionary adjustments made pursuant to the Plan and
          to any limitations contained in Plan, awards for the Chief Executive
          Officer will determined by multiplying the Participant's Target Award
          by the sum of

               a.   30% of the Individual Performance Factor (as defined in C);
                    and

               b.   70% of the CEO Corporate Performance Factor (as defined in
                    D).

     6.   Awards generally shall be made only to

               a.   Participants who are in the employ of the Company on the
                    date of payment, and

               b.   the estates of, or beneficiaries designated by, Participants
                    who shall have died while employed during the Plan Year.

         However,  pro-rated awards for  Participants  who terminate  employment
         during a Plan Year may at the  discretion  of the  Manager and with the
         endorsement  of the Chief  Executive  Officer,  be  recommended  to the
         Committee for consideration based on the conditions of the case.

     7.   At the discretion of the Manager and the Vice President of Human
          Resources and with the endorsement of the Chief Executive Officer,
          pro-rated awards may be recommended for individuals who become
          Participants subsequent to the beginning of a Plan Year.

     8.   Recommended awards for Participants whose target levels change during
          the Plan Year will be based on the target level in effect when the
          calculation is made.

     9.   The aggregate of all Participant's incentive awards determined under
          this Exhibit A will be recommended to the Committee for its
          consideration. Incentive awards determined for





          Participants who are members of the Section 16 Group will be
          separately set forth for the Committee's consideration.

     10.  Before the calculated awards are presented to the Committee, the award
          for any Participant or group of Participants may be adjusted, upward
          or downward, at the discretion of the Chief Executive Officer. The
          recommended award for any Participant, or group of Participants, may
          be adjusted, upward or downward, at the discretion of the Committee.
          Examples of factors that could lead to an adjustment are the
          subjective criteria such as the Participant's initiative, leadership,
          teamwork, judgment, and creativity.

     11.  Notwithstanding any other provision of this Plan, in no event will an
          incentive compensation payment under this Plan to any Participant for
          a Plan Year exceed 205% of the Participant's Target Award for that
          Plan Year.

     12.  Notwithstanding any awards authorized by the Committee for a Plan
          Year, the Committee may, in its sole discretion, cancel or adjust
          downward the unpaid awards for any or all Participants based on the
          results of the audit of the Company's financial statements for the
          Plan Year by the Company's independent registered public accountant.

B.   TARGET LEVELS

Target levels are based on the level of  importance  and  responsibility  of the
position in the  organization.  Where a range has been  established,  the actual
target level is determined by the Manager and Vice President of Human Resources,
subject to approval by the Chief Executive Officer. The Committee determines the
actual  target  level  for the  Chief  Executive  Officer  and each of the other
members of the Section 16 Group.


                              Position                      Target Level
                   President and Chief Executive              70-150%
                   Officer
                   Chief Financial Officer                    70-125%
                   Chief Operating Officer                    70-125%
                   Business Unit and Functional               50-125%
                   Unit Heads
                   Other Eligible Positions                   10-100%


C.   INDIVIDUAL PERFORMANCE FACTORS

     1.   At or near the beginning of each fiscal quarter, performance goals for
          each Participant shall be set by the Participant and the Participant's
          Supervisor. These quarterly individual performance goals are weighted
          by the Participant and Supervisor to reflect the importance of each
          objective and are generally referred to as "Most Important Tasks
          (MITs)". MITs for the Chief Executive Officer shall be set by the
          Chief Executive Officer and the Committee. From time to time the
          Chairman of the Board may assist the Committee with respect to the
          MITs of the Chief Executive Officer.

     2.   Establishment of MITs

               a.   Each quarter the Chief Executive Officer will disseminate
                    general financial goals and strategic objectives to the
                    Managers. The Mangers will, in turn, disseminate their
                    tactical plans and objectives to the Supervisors to assist
                    in the development of Participants' MITs.

               b.   MITs are generally to be established in a manner so as to be
                    specific, measurable, and time specific. MITs should be
                    attainable and realistic but also provide some challenge to
                    achieve results above the norm.





               c.   Each Participant's quarterly MITs will include individual
                    performance goals related to technical, operational,
                    financial, and/or managerial matters such as

                     o    research and development
                     o    product development cycle time
                     o    patent activity
                     o    design wins, in terms of customer programs or
                              reference designs
                     o    operations performance
                     o    systems improvements
                     o    supplier contracts or issues
                     o    production contracts or issues
                     o    customer contracts or issues
                     o    foundry management
                     o    supply chain management
                     o    inventory control
                     o    manufacturing efficiencies, including improvement of
                              variances
                     o    quality and reliability
                     o    order fulfillment and delivery performance
                     o    sales support
                     o    marketing to key customers
                     o    obtaining new customers
                     o    customer support, including application matters
                     o    bookings
                     o    billings
                     o    achievement of cost savings
                     o    budget achievement
                     o    free cash flow
                     o    working capital
                     o    return on equity
                     o    return on sales
                     o    return on assets
                     o    margin improvements
                     o    investor relations
                     o    corporate governance
                     o    filling key positions
                     o    legal matters
                     o    strategic initiatives

                    The cumulative weighting of such individual performance
                    goals shall total to 100% for each Participant. The actual
                    weighting of a Participant's individual performance goals
                    shall be determined by the Participant's Supervisor. The
                    actual weighting of the Chief Executive Officer's individual
                    performance goals shall be determined by the Committee.

               d.   Changes or substitutions in objectives and/or weighting must
                    have the endorsement of both the Participant's Supervisor
                    and Manager. Such changes with respect to the Chief
                    Executive Officer shall require the approval of the
                    Committee.

     3.   Scoring of MITS

         After the end of each fiscal quarter,  each  Participant's  performance
         against the MITs  established  for the quarter shall be assessed by the
         Participant's   Supervisor.   Quarterly  MITs  scoring  for  the  Chief
         Executive  Officer shall be performed the Committee.  From time to time
         other  Board  members may assist the  Committee  in review of the Chief
         Executive Officer's performance.

               a.   Objectives may be evaluated on a partial credit basis.





               b.   A Participant may receive a quarterly MITs score in excess
                    of 100% based upon exceptional performance, but only with
                    the review and approval of (a) the Participant's Manager and
                    endorsement of either (i) the Chief Executive Officer or
                    Chief Operating Officer (with respect to Participants in
                    Business Units) or (ii) the Chief Executive Officer (with
                    respect to Participants in corporate functional groups and
                    members of the Section 16 Group) or (b) the Committee, with
                    respect to the Chief Executive Officer.

     4.   After the end of the Plan Year, each Participant's quarterly MITs
          scores shall be averaged to arrive at the Participant's Individual
          Performance Factor.

     5.   The Individual Performance Factor for any Participant, or group of
          Participants may be adjusted, upward or downward, at the discretion of
          the Chief Executive Officer or the Committee.



D.   ORGANIZATIONAL PERFORMANCE FACTORS

     1.   Establishment of Formulas

               a.   At the time the bonus pool is established by the Committee,
                    the Committee will also determine the percentage of the
                    Business Plan that must be achieved (in terms of EBIT) in
                    order to use 100% as the Corporate Performance Factor in the
                    award calculation. In doing so, the Committee will establish
                    a formula for generating the Corporate Performance Factor
                    for lesser and superior performance against the Business
                    Plan. In most circumstances, 100% achievement of the
                    Business Plan will equate to a 100% Corporate Performance
                    Factor, but the Committee may establish a different
                    correlation. The Committee may adjust the formula to
                    establish a higher performance threshold that must be
                    attained before any value is assigned to the Corporate
                    Performance Factor. In no event will the formula result in a
                    Corporate Performance Factor of more than 250%.

                    For example, a formula established by the Committee may
                    correlate attainment of 100% of the Business Plan with a
                    100% Corporate Performance Factor, attainment of 120% of the
                    Business Plan with a 150% Corporate Performance Factor, and
                    attainment of 60% or less of the Business Plan with a
                    Corporate Performance Factor of zero. Even though the
                    formula results in a Corporate Performance Factor of zero at
                    a 60% performance level, the Committee may adjust the
                    formula to require better performance, say 70% attainment of
                    the Business Plan, before any value is assigned to the
                    Corporate Performance Factor.

               b.   Taking into account the Chief Executive Officer's leadership
                    role in attaining the Business Plan, the Committee will
                    likewise establish a formula for the CEO Corporate
                    Perfomance Factor. This formula may be the same as the
                    Corporate Performance Factor formula or may vary from it.
                    For example, the Committee may establish a formula that
                    results in a higher CEO Corporate Performance Factor than
                    Corporate Performance Factor for the same level of
                    acheivement over and above the Business Plan and/or which
                    results in a lower CEO Corporate Performance Factor than
                    Corporate Performance Factor for the same level of
                    achievement if the Business Plan is not met. In no event
                    will the formula result in a CEO Corporate Performance
                    Factor of more than 250%.

               c.   The Committee will likewise establish formulas with respect
                    to the Business Plan of each Business Unit. In no event will
                    any formula result in a Business Unit Performance Factor for
                    any Business Unit of more than 250%.

               d.   The formulas with respect to Corporate Performance Factor
                    and CEO Corporate Performance Factor may be adjusted by the
                    Committee at any time during the Plan Year to reflect
                    changes in the Company's structure, such as the acquisiton
                    or disposition of a line of business. Similarly, the
                    formulas with respect to Business Unit Performance may be
                    adjusted by the Committee at any time during the Plan Year
                    to reflect changes in Business Unit structure such as the
                    combining of Business Units.





     2.   Calculation of Organizational Factors

               a.   After the end of each Plan Year, the actual EBIT performance
                    of the Company will be compared to the Business Plan. The
                    percentage of the Business Plan achieved will be used in the
                    formulas previously established by the Committee to
                    determine the Corporate Performance Factor carried into the
                    award computation and the CEO Corporate Performance Factor
                    carried into the CEOs award computation. The Corporate
                    Performance Factor may be adjusted upward or downward at the
                    discretion of the Chief Executive Officer, for example to
                    address an extraordinary item, but in no event will such
                    adjustment result in a Corporate Performance Factor of more
                    than 250%.

               b.   Likewise, after the end of each Plan Year, the actual EBIT
                    performance of each Business Unit will be compared to the
                    Business Plan for the Business Unit. The percentage of the
                    Business Unit Business Plan achieved used in the formula
                    previously established by the Committee to determine the
                    Business Unit Performance Factor carried into the award
                    computation. The Business Unit Performance Factor for any
                    Business Unit may be adjusted upward or downward at the
                    discretion of the Chief Executive Officer, but in no event
                    will such adjustment result in a Business Unit Performance
                    Factor of more than 250%.

               c.   The CEO Corporate Performance Factor, the Corporate
                    Performance Factor and the Business Unit Performance Factors
                    may be adjusted, upward or downward, at the discretion of
                    the Committee, but in no event will such adjustment result
                    in a CEO Corporate Performance Factor, Corporate Performance
                    Factor or Business Unit Performance Factor of more than
                    250%.
