Effective as of July 21, 2008, MAKO Surgical Corp. (the "Company") and Steven J. Nunes, the Company's Senior Vice President of Sales and Marketing, entered into an amendment (the "Amendment") to Mr. Nunes' employment agreement dated as of May 15, 2006, as amended, to provide for the establishment of a cash bonus plan for 2008 for the benefit of Mr. Nunes (hereinafter, the "2008 Nunes Bonus Plan").

Mr. Nunes will be eligible for an award under the 2008 Nunes Bonus Plan if the Company attains a minimum of eighty percent (80%) of the sales-related performance goals set forth on the Company's 2008 Metrics Scorecard (the "Scorecard"). Such performance goals are further described in the Company's Current Report on Form 8-K filed with the Securities and Exchange Commission on April 29, 2008 (the "April 29 Form 8-K").

In the event that the minimum percentage of such performance goals is achieved, the minimum and maximum amounts payable to Mr. Nunes pursuant to the 2008 Nunes Bonus Plan are $80,000 and $100,000, respectively. Calculation of the actual amount of the award to be distributed to Mr. Nunes under the 2008 Nunes Bonus Plan will be based on a point system derived from weighting the sales-related performance goals set forth on the Scorecard. Under the terms of the 2008 Nunes Bonus Plan, if certain goals are met, Mr. Nunes will also be eligible to receive a grant of Forty Thousand (40,000) incentive stock options to purchase shares of the Company's common stock pursuant to its 2008 Omnibus Incentive Plan.

Any bonus award distributed to Mr. Nunes under the 2008 Nunes Bonus Plan will be in addition to any cash bonus that Mr. Nunes is eligible to earn under the Company's 2008 Leadership Cash Bonus Plan, a description of which was attached as Exhibit 10.2 to the April 29 Form 8-K. A copy of the 2008 Leadership Cash Bonus Plan, which was previously approved and adopted by the Compensation Committee of the Company's Board of Directors and reduced to writing as of July 21, 2008, is attached hereto as Exhibit 10.1 and incorporated herein by this reference.

The foregoing description of the terms and conditions of the 2008 Nunes Bonus Plan is qualified in its entirety by reference to the Amendment, a copy of which is attached hereto as Exhibit 10.2 to this Form 8-K and incorporated herein by this reference.
