The determination of the arbitrator shall be final, conclusive and binding on the parties.

7. WITHHOLDINGS. The Company shall deduct all federal, state, local and other taxes or withholdings required by law to be withheld with respect to any all amounts paid under this Plan.

8. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.

9. NON-TRANSFERABILITY OF RIGHTS.

9.1 NO TRANSFERS.

An Executive Officer may change such designation of his or her beneficiary at any time by written notice, subject to the above spousal consent conditions.

9.3 EFFECT OF NO DESIGNATION. If an Executive Officer dies and there is no living beneficiary validly designated under this Plan, any payments under this Plan due to the Executive Officer will be made to the executor or administrator of the estate of the Executive Officer.

9.4. RIGHTS OF PARTICIPANTS AND BENEFICIARIES. The Company shall pay all amounts payable hereunder only to the Executive Officer or any beneficiaries properly designated pursuant to this Plan. The Company shall not be liable for the debts, contracts or engagements of any Executive Officer or his or her beneficiaries, and rights to payments under this Plan may not be taken in execution by attachment or garnishment, or by any other legal or equitable proceeding, while in the hands of the Company.

9.5 REPLACEMENT EXECUTIVE OFFICERS. If an Executive Officer ceases to work for the Company or Kaiser on a full time or part time basis, the Committee may in its discretion elect to allow a replacement Executive Officer (provided the replacement is not already an Executive Officer) to participate in the Incentive Performance Bonus Pool in any amount up to but not exceeding the amount that would have been received by the former Executive Officer.

10. NO RIGHT TO CONTINUED EMPLOYMENT. This Plan shall not confer upon a Executive Officer any right with respect to continuing the Executive Officer’s employment or consulting relationship with the Company and/or Kaiser, nor shall it interfere in any way with the Executive Officer right or the Company’s right to terminate such employment or consulting relationship at any time, with or without cause. This Plan shall not affect the rights of the Executive Officers or any other employees to participate under other plans of the Company.

11. FUNDING; RIGHTS TO PAYMENT. This Plan is an unfunded arrangement. To the extent any Executive Officer acquires a right to receive payments under the Plan, such rights shall be no greater than the right of any unsecured creditor of the Company. Nothing contained in this Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or fiduciary relationship among the Company, Kaiser and any Executive Officer, which shall continue to be as it was without reference to this Plan.

12. ADMINISTRATION.

12.1 ADMINISTRATOR. The Plan shall be administered by the Committee selected by the Board. The Committee shall initially consist of the members of Kaiser’s Human Relations Committee. The Committee may increase the size of the Committee and appoint additional members, remove members (with or without cause) and substitute new members, fill vacancies (however caused), and remove all members of the Committee and thereafter directly administer the Plan, all to the extent permitted by applicable laws, and to the extent relevant, the rules for qualification as “performance-based compensation” under Section 162(m).

The right to earn awards under this Plan will expire on the earlier of the distribution of substantially all the cash proceeds to Kaiser members resulting from a sale of Kaiser’s assets or December 31, 2016.

Exhibit “A”

BUSINESS STAFFING, INC. NEW REVENUE PARTICIPATION INCENTIVE PLAN

EXAMPLES OF NEW REVENUE, NEW REVENUE EXPENSES, CALCULATION AND PAYMENT OF

THE INCENTIVE PERFORMANCE BONSUS POOL

EXAMPLE 1

Assume during calendar year 2008, Kaiser received $225,000 from the lease of its Kaiser Eagle Mountain facilities for military training under a five (5) year contract, $36,000 from the lease of houses at Eagle Mountain, and $80,000 from the sale of two lots at Lake Tamarisk. One of Kaiser’s employees was paid $2,000 in over time directly related to the military training conducted Eagle Mountain, an air conditioning unit was replaced at one of the houses rented for a full year at a price of $5,000 and it has an estimated useful life of 10 years, and a 6% commission was paid in connection with the sale of the Lake Tamarisk Lots. In this example, items that would constitute New Revenue would be: (i) the $225,000 received from the lease of the Eagle Mountain facilities for military training; and (ii) the $36,000 received from the rental of houses at Eagle Mountain. New Revenue would not include the sale of the Lake Tamarisk lots as those are existing assets of Kaiser. New Revenue Expenses would be: (i) the $2,000 in overtime paid to Kaiser’s employee but no portion of his regular salary would be a New Revenue Expense; and (ii) the full cost of the air conditioning unit of $5,000 because it was a capital asset with a purchase price of less than $10,000. New Net Revenue would be $254,000 calculated as follows: New Revenue of $261,000 ($225,000 + $36,000) less New Net Revenue Expenses of $7,000. The Incentive Performance Bonus Pool would equal $45,720 calculated as follows: (18% of $254,000). In addition, assume that the fair market value of Kaiser’s Class A Units was determined to be $.50. Each of the three Executive Officers would receive an incentive performance bonus of $15,240 payable as follows: 50% in Class A Units at $.50 per unit which would result in 15,240 units being issued to each officer (no fractional units would be issued) and $7,120 in cash or a SERP contribution.

EXAMPLE 2

Assume the same facts as in Example 1 above, but also assume that Kaiser spent an additional $25,000 to construct a high speed internet line for the direct benefit of the military training exercises which is amortized over five years and it sold rock products for a royalty of $3.00 per ton and it sold 50,000 tons for a highway construction project for a total of $150,000. Outside legal services for $12,000 were spent to collect the revenues generated from the lease of the Eagle Mountain facility for military training. In addition, to those items identified above as New Revenue, the sale of the rock for $150,000 would be New Revenue and the amount paid in legal expenses and the amortized costs of the high speed internet line would be New Expenses. In this example, the New Net Revenue of $387,000 would be calculated as follows: New Revenue of $411,000 consisting of: (i) Military training revenues of $225,000 + housing rentals of $36,000 + rock sales of $150,000. From New Revenue would be subtracted New Revenue Expenses of $24,000 consisting of: (i) $2,000 in overtime; (ii) $5000 which is the full cost of the new air conditioning unit since its purchase price was less than $10,000; (iii) $5,000 which is the amortized cost of the new internet line; and (iv) $12,000 which is the legal fees to collect the military training rent. The Incentive Performance Bonus Pool would equal $69,660 calculated as follows: (18% of $387,000). Each of the Executive Officers would receive an

9

incentive bonus of $23,220 payable 50% in Class A Units and 50% in either cash or a contribution to the SERP. The number of Class A Units to be issued to each Executive Office in the example would be 23,220 units (no fractional units would be issued) and $11,610.00 in either cash or a SERP contribution.
