Exhibit 10.4

SMX Staff Executive Officer Bonus Terms for FY06 Under the

Section 162(m) Executive Officer
Performance-Based Bonus Plan



Plan Objective



Suns SMX Staff Executive Officer Bonus Terms for FY06 under its Section 162(m) Executive Officer Performance-Based Bonus Plan
(the Plan) are designed to compensate Executive Officers who are SMX Staff members, other than the Chief Executive Officer (SMX Staff) for contributions to Sun during the fiscal year. The Plan provides for quarterly cash
compensation based on performance against the Plan measures.



Plan
Year/Performance Periods



The Plan year is Suns fiscal year
2006. The Performance Periods (as such term is defined in the Plan) are each of Suns four fiscal quarters during that fiscal year.



Eligibility



These terms apply to persons serving as members of Suns SMX Staff as of July 1, 2005. In order to receive a bonus payment with respect to any fiscal quarter, the participant must be serving as a member of
Suns SMX Staff as of the last day of that fiscal quarter, except as provided below.



A participant who retires, becomes disabled, or dies during any fiscal quarter may receive a prorated bonus for the period of time during the fiscal quarter that the participant provided services to Sun. A participant
who leaves Sun prior to the end of a fiscal quarter for any other reason, including but not limited to a reduction in force, voluntary resignation, or termination by Sun, will be ineligible for a bonus payment with respect to that fiscal quarter and
any subsequent fiscal quarter during fiscal year 2006.



Bonus Target



The bonus target under the Plan for members of SMX Staff is 90% of
the participants Eligible Wages for fiscal year 2006, as determined below (the Bonus Target). The Bonus Target is divided between the four fiscal quarters of fiscal year 2006 as follows (each, a Quarterly Bonus Target):



|               |  |            |   |  |                        |  
|-------------- |  | ---------- | - |  | ---------------------- | -
|Fiscal Quarter |  | Percentage |   |  | Quarterly Bonus Target |  
|FY06 Q1        |  | 10         | % |  | 9                      | %
|FY06 Q2        |  | 25         | % |  | 22.5                   | %
|FY06 Q3        |  | 25         | % |  | 22.5                   | %
|FY06 Q4        |  | 40         | % |  | 36                     | %



For example, for FY06 Q1, the
Quarterly Bonus Target would be 90% multiplied by 10%, or 9% of Eligible Wages for that quarter.



Payouts under the Plan are capped at the lesser of 300% of the Bonus Target or $7.5 million for fiscal year 2006.



Eligible Wages



Eligible Wages with respect to any fiscal quarter in fiscal year 2006 (Eligible Wages) shall be determined based upon the
participants annual base salary on the last day of such fiscal quarter (September 25, 2005 for FY06 Q1, December 25, 2005 for FY 06 Q2, March 26, 2006 for FY06 Q3, and June 30, 2006 for FY06 Q4).

For example, for FY06 Q2, assuming the participants annual base salary on December 25, 2005 was $400,000,
the participants Eligible Wages would be $400,000.



Eligible Wages exclude relocation allowances, expense reimbursements, tuition reimbursement, car/transportation allowances, expatriate allowances, long-term disability payments, or other commissions and bonuses paid during each quarter
