                          LETTER AGREEMENT AMENDMENT
               BETWEEN EUGENE W. TEAL AND COMPUTER MOTION, INC.

WHEREAS on January 7, 2002, Mr. Eugene W. Teal acknowledged and accepted an
offer from Computer Motion, Inc. ("CMI," and collectively with Mr. Teal, "the
parties") for the position of Executive Vice President on terms provided in a
January 7, 2002 written communication ("the Offer");

WHEREAS the Offer included (i) various provisions concerning the payment of
annual salary to, and eligibility for an annual bonus for, Mr. Teal, and (ii)
various provisions concerning a two (2) year "no cut" contract and payments over
a three (3) year period should CMI "be bought out or acquired by [sic] or
experience a change in control";

NOW, THEREFORE, to resolve perceived uncertainties in the Offer, to resolve a
potential good faith disagreement over how the Offer is to be properly
interpreted, and to agree to a good faith amendment and settlement of the
uncertainty and clarify the original intent of both CMI and Mr. Teal, the
Parties desire, and hereby do agree, to restate and amend the financial terms of
the Offer as follows:

(1) Upon a buy-out or acquisition of CMI or an experienced change in control
(which the Parties agree will occur, for example, upon consummation of the
presently proposed merger between CMI and Intuitive Surgical, Inc.
("Intuitive")), CMI agrees to pay to Mr. Teal his salary of $160,000 per year
for three (3) years, with a 5% increase per year, which will result in payment
of $160,000 for the first year, $168,000 for the second year, and $176,400 for
the third year. For purposes of this provision only, and regardless of when a
buy-out or acquisition or change in control ultimately occurs, if ever, this
three-year period of salary payments shall run commencing from the first date of
Mr. Teal's employment with CMI, namely October 4, 2001. Other than as set forth
in (2), no bonus will be paid as part of this three-year commitment.

(2) In addition to (1), CMI will abide by its commitment to pay to Mr. Teal a
bonus of $80,000, or 50% of his salary for the first year of his employment with
CMI, half of which amount has already been paid to Mr. Teal, which payment Mr.
Teal hereby acknowledges, and half of which is still to be paid as of the date
of this Amendment.

(3) The Parties further clarify that the "two (2) year `no cut' contract"
provision of the Offer guaranteed only the payment of Mr. Teal's salary for the
two-year period from October 4, 2001.

(4) The Parties agree that this Amendment supercedes and modifies paragraphs 1,
2 and 4 of the preceding Offer, and further agrees that satisfaction of the
financial terms of this Amendment by CMI shall constitute full satisfaction of
all remaining and outstanding obligations, claims and causes of action between
CMI and Mr. Teal, upon which payments Mr. Teal's employment with CMI and any
surviving entity shall terminate.

Read, Understood, Accepted and Agreed to this 25th day of March, 2003.
