2008 LEADERSHIP CASH BONUS PLAN

The MAKO Surgical Corp. 2008 Leadership Cash Bonus Plan is designed to attract, retain and motivate management-level employees by providing meaningful annual cash incentives. Capitalized terms set forth herein are defined in the “Definitions” section below.

The Committee shall administer and interpret this Plan. The Committee shall also have the sole authority to establish such rules and regulations, not inconsistent with the provisions of this Plan, as it deems necessary or desirable for the proper administration of the Plan and shall make such determinations and interpretations under and in connection with this Plan as it deems necessary or desirable, including without limitation the determination of the Distribution Date and the Scorecard Percentage, Target Bonus Percentages and Baseline Percentages to be used to calculate Bonuses for the Plan Year.

This Plan, and all such rules, regulations, determinations and interpretations of the Committee, shall be binding on the Company and all Participants and upon their legal representatives, heirs, beneficiaries, successors and assigns and upon all other persons claiming under or through any of them.

Each active, full-time management-level employee of the Company, in good standing, as determined by the Committee, on the Measurement Date (except as specifically provided below under the caption, “Termination of Employment; Death; Disability”) whose Employment Start Date preceded October 1 of the Plan Year may participate in this Plan. The Committee, in its discretion, will determine, on a case-by-case basis, the eligibility of management-level employees to participate in this Plan who are hired during the fourth quarter of the Plan Year.

After the Measurement Date, the Committee will review the Scorecard to determine, for purposes of awarding Bonuses under this Plan, whether the Company attained the minimum Scorecard Percentage.

If the Company has attained the minimum Scorecard Percentage for the Plan Year, a Bonus shall be awarded to each Participant. The amount of the Bonus shall be calculated by multiplying that Participant’s Base Salary by the applicable Target Bonus Percentage (as described below).

If the Company has attained a Scorecard Percentage that falls in between the minimum and maximum Scorecard Percentages, so that the Target Bonus Percentage must be prorated, the amount of the Bonus to be awarded to each Participant shall be calculated by multiplying that Participant’s Base Salary by the applicable Actual Bonus Percentage.

Target Bonus Percentages are the minimum and maximum percentages of Base Salary established by the Committee that will apply for the Plan Year at each Management Level.

Unless otherwise determined by the Committee, if a Participant moves to a higher Target Bonus Percentage level during the Plan Year, that Participant’s Target Bonus Percentage will be reset at the higher level for the entire Plan Year. If a Participant moves to a lower Target Bonus Percentage level during the Plan Year, that Participant’s Target Bonus Percentage will be reset at the lower level for the entire Plan Year.

No Bonus will be paid to any individual who is not a Participant on both the Measurement Date and the Distribution Date, except if due to death or disability, unless otherwise specifically agreed by the Board or the Committee.

Any Participant who dies or becomes Permanently Disabled during the Plan Year will be paid a Bonus (if and to the extent awarded under this Plan) based upon the actual Base Salary paid to the Participant from the beginning of the Plan Year through the date of retirement, death or Permanent Disability. Any such Bonus will be paid on the Distribution Date.

Bonus awards for the Plan Year will be paid in ca
