BASIS OF CALCULATION OF ENTITLEMENTS 1.1 The entitlement of each Eligible Employee under the Scheme shall be calculated as such percentage of pay applicable to all eligible employees if any, as the Directors shall allocate for each Profit Sharing Period PROVIDED that in the case of any Eligible Employee, the total of the entitlements in any year of assessment shall not exceed the amount for the time being specified as being the limit on individual appropriations for the purposes of paragraph 1(4) of the Third Schedule to the Act. 1.2In addition, the employees may choose to allocate all or part of their bonus entitlement as calculated under 1.3 into the Profit Sharing Scheme. The total of the entitlements in any year of assessment shall not exceed the amount for the time being specified as being the limit on individual appropriations for the purposes of paragraph 1(4) of the Third Schedule to the Act. 1.3The employee bonus plans are outlined below. 1.3(A) outlines the method in which the bonus is calculated for direct manufacturing employees and 1.3(B) outlines the method in which the bonus is calculated for indirect employees. 1.3(A) MANUFACTURING BONUS PLAN Objective: To recognise the contribution of manufacturing personnel in the achievement of quality, availability and cost goals. Eligibility: All permanent full time employees who are employed on a permanent basis on the first working day of the quarter for which the bonus is being issued. The employee must also be continuously employed by the company and be active on the date when the bonuses are distributed. All bonuses are issued at the sole discretion of the executive management of the company. The decision of this group is final. Methodology: At each quarter end APCC reviews the previous quarter's performance and financial results. Under normal business circumstances, each direct employee, subject to eligibility contributions above, may share financially in this business performance. To calculate the manufacturing bonus, four categories of individual and cell performance are added to obtain the percentage for the overall bonus. These categories may change from quarter to quarter. At the start of every quarter, the Manufacturing Operations Manager for each division will set and agree goals and targets for the forthcoming quarter for hourly paid employees. For example in Quarter 4 of 1997 the following categories were used, 1. Housekeeping (20%) 2. Cycle Counting (30%) 3. Quality (20%) 4. Time-keeping & Attendance (30%) Housekeeping (20%) Housekeeping Audits are to be conducted on each cell throughout Q4 and 20% of the bonus is allotted for housekeeping based on the average weekly score of each cell. Cycle Counting (30%) Cycle counting is based on how close to the expected target each cell achieved throughout Q4. Cycle counting is to be done on a weekly basis and an average figure obtained for all of Q4. 30% of Q4 bonus is allocated to Cycle Counting. Quality (20%) 20% of Q4 bonus is to be allocated to Quality. The percentage is calculated on a cell basis taking into account both ICT & Final testing. Each cell is set a goal and based on how close they come to this goal determines the percentage figure awarded to that cell. Time-keeping & Attendance (30%) Attendance is measured individually and is made up of two parts a) Absence Every individual can attain thirty percentage points by their good attendance. Poor attendance will impact this, each certified absence ten (10) percentage points will be deducted from the total thirty. Uncertified absences will result in forfeiture of bonus. b) Lates / Early leaves In addition to points being deducted for absences, points will also be deducted for lateness and early leaves. For every time an employee is either late or leaves early, a total of 5 percentage points will be deducted from the total attendance percentage for each occurrence. Forfeiture of Bonus The purpose of our bonus plan is to allow employees the opportunity to share in APCC's success as one of the fastest growing companies in the world. However, there are times when the actions of an employee might cause him/her to forfeit his/her bonus. - If an employees total percentage points lost fo absences, tardiness, or early leaves exceeds 30 points, creating a negative number for possible attendance points, that employees will not receive a bonus for that quarter. - If an employee received a written warning for any reason during a quarter, that employee will forfeit bonus for the quarter in which the warning was issued. - If an employee has an uncertified absence. Effective: This policy is effective October 6, 1997.

ELIGIBILITY: All permanent full time employees who are employed on a permanent basis on the first working day of the quarter for which the bonus is being issued. The employee must also be continuously employed by the company and be active on the date when the bonuses are distributed. All bonuses are issued at the sole discretion of the executive management of the company. The decision of this group is final. METHODOLOGY: At each Quarter end APCC reviews the previous quarter's performance and financial results. Under normal business circumstances, each indirect employee subject to the eligibility conditions as above, may share financially in this business performance. The basis of calculation is the multiple / addition of a) x b) x c) or a) x b) where determined by Corporate Management a) Incentive Bonus Percentage (IBP) - Corporate assessment of Quarterly performance b) Local Divisional Percentage (LDP) - Local management assessment of contribution c) Individual Performance Factor (IPF) - Manager's assessment of employee's personal contribution and objective achievement. All Bonus Payments and Methodologies are at the sole discretion of the Executive Management of the Company. The resultant percentage will be applied to the employee's gross earnings of the previous quarter less payment of any other period's bonus and processed through payroll as normal. GUIDELINES: The following serves as guidelines for implementation. The aggregate payment for individual departments / divisions will not exceed the multiple of IBP and the LDP. EFFECTIVE DATE: This policy is effective October 6 1997 and can only be revised by Human Resources.
