2008 LEADERSHIP CASH BONUS PLAN

Purpose of the 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.
Administration:	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.
Participants:	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.
Determination of Bonus Awards:	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:	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.

Termination of Employment; Death; Disability:	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.
Payment of Bonus Awards:	Bonus awards for the Plan Year will be paid in cash to a Participant (or to his or her beneficiary, in the event of death) on the Distribution Date, which will occur on or before March 15, 2009.
	Except in the event of death, no benefit payable under this Plan shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge, and any such attempted action shall be void and no such benefit shall be in any manner liable for or subject to debts, contracts, liabilities, engagements or torts of any Participant or former Participant.
Absence of Liability:	A member of the Board or the Committee or any officer of the Company shall not be liable for any act or inaction hereunder, whether of commission or omission.
Funding of Plan:	The Company shall not be required to fund or otherwise segregate any cash or any other assets that may at any time be paid to Participants under this Plan. This Plan shall constitute an “unfunded” plan of the Company. The Company shall not, by any provision of this Plan, be deemed to be a trustee of any property, and any rights of a Participant or former Participant shall be limited to those of a general unsecured creditor.
Withholding:	The Company shall have the right to make such provisions as it deems necessary or appropriate to satisfy any withholding obligations it may have under federal, state or local income or other tax laws. The Company shall have no liability for any tax imposed on a Participant as a result of amounts paid or payable to the Participant under this Plan.
Amendment, Suspension or Termination of Plan:	In the sole discretion of the Committee or the Board, this Plan, or any of its provisions, may from time to time be amended, suspended or terminated in whole or in part, and if suspended or terminated, may be reinstated.
No Right to Bonus or Continued Employment:	Neither the establishment of the Plan nor the provision for or payment of any amounts hereunder, nor any action of the Company, the Board or the Committee in respect of this Plan, shall be held or construed to confer upon any person any legal right to receive, or any interest in, a Bonus under this Plan, or any legal right to be continued in the employ of the Company or of any Company subsidiary or affiliate. The Company expressly reserves any and all rights to discharge a Participant in its sole discretion, without liability to any person, entity or governing body under this Plan or otherwise.
Successors and Assigns:	This Plan shall be binding upon the Company’s successors and assigns.
