          THIS FIRST AMENDMENT TO EMPLOYMENT AGREEMENT (this “Amendment”) is
made effective as of April 13, 2010 (the “Effective Date”), by and between Ivan
Delevic (“Employee”) and MAKO Surgical Corp. (“Company”).

          WHEREAS, Employee and Company have entered into that certain
Employment Agreement, effective as of April 27, 2010 (the “Agreement”); and

          WHEREAS, Employee and Company desire to amend the Agreement to correct
a scrivener’s error and provide additional clarification with respect to
Employee’s relocation package;

          THEREFORE, in consideration of the mutual covenants, agreements,
representations and warranties contained in the Agreement and this Amendment,
the parties hereby agree as follows:

1.        In order to correct a scrivener’s error, clause (i) of the last
sentence of Section 2(e) of the Agreement is hereby amended to provide that the
maximum aggregate Gross Payments (including the gross amounts of the Net
Payments) to be made by the Company to Employee under all of the Relocation
Allowance, the Travel Allowance, the Housing Allowance, and the Closing
Allowance shall be One Hundred Twenty Eight Thousand Five Hundred Dollars
($128,500).

2.        Section 2(e) of the Agreement is hereby amended to insert the
following at end of such section:

          Notwithstanding the foregoing, the parties agree that at the sole
discretion of the Company’s Chief Financial Officer, any amount available under
each of the four allowances (i.e. Relocation Allowance, the Travel Allowance,
the Housing Allowance, and the Closing Allowance) may be applied toward any one
or more of the remaining three allowances subject in all cases to the maximum
aggregate Gross Payment of One Hundred Twenty Eight Thousand Five Hundred
Dollars ($128,500).

3.        Unless otherwise defined herein, capitalized terms shall have the same
meaning as described in the Agreement.

4.        Except as expressly provided herein, all terms and conditions set
forth in the Agreement to which this Amendment applies, shall remain in full
force and effect. In the event of a conflict between this Amendment and the
Agreement, this Amendment shall be controlling.

5.        This Amendment may be executed in counterparts, each of which are
deemed to be original, but both of which together constitute one and the same
instrument. Copies of signatures sent by facsimile transmission are deemed to be
