Item 8.01. Other Events

On May 27, 2009, Maurice R. Ferré, M.D., Chairman, Chief Executive Officer, and President of MAKO Surgical Corp. (the "Company"), entered into a pre-arranged stock trading plan to sell a portion of his shares of the Company's common stock in accordance with the guidelines specified by Rule 10b5-1 under the Securities Exchange Act of 1934 and the Company's insider trading policies. Rule 10b5-1 permits an officer or director to enter into a pre-arranged plan for buying or selling Company stock at a time when the officer or director is not in possession of material, nonpublic information about the Company. After adoption of a Rule 10b5-1 plan, the officer or director retains no further discretion in carrying out the trades under the plan, although the officer or director may later amend or terminate the plan. The existence of such a plan allows for personal holdings to be diversified in an orderly fashion from time to time, often as part of a personal financial, tax, or estate planning strategy.

The Rule 10b5-1 plan adopted by Dr. Ferré provides for the sale of up to 100,000 shares of the Company's common stock at specified market prices commencing thirty days after adoption of the plan and continuing until all 100,000 shares are sold or December 31, 2010, whichever occurs first. Any transaction under this plan will be reported to the Securities and Exchange Commission in accordance with applicable securities laws, rules, and regulations.

The Company does not intend to report on Form 8-K any Rule 10b5-1 plans that may be adopted by any other officers or directors. In addition, the Company undertakes no obligation to report any modifications or terminations of any publicly announced trading plan, except to the extent as may be required by law.
