       AMENDMENT TO AMENDED AND RESTATED PREFERRED SHARES RIGHTS AGREEMENT

1.       GENERAL BACKGROUND. In accordance with Section 27 of the Preferred
         Shares Rights Agreement between Fleet Bank f/k/a BankBoston, N.A. (the
         "Rights Agreement") and LSI Logic Corporation ("abbreviated name")

         Logic Corporation desire to amend the Agreement to appoint EquiServe
         Trust Company, N.A.

2.       EFFECTIVENESS. This Amendment shall be effective as of August 16, 2001
         (the "Amendment") and all defined terms and definitions in the
         Agreement shall be the same in The Amendment except as specifically
         revised by the Amendment.

3.       REVISION. The section in the Agreement entitled "Change of Rights
         Agent" is hereby deleted in its entirety and replaced with the
         following:

         Change of Rights Agent. The Rights Agent or any successor Rights Agent
         may resign and be discharged from its duties under this Agreement upon
         30 days' notice in writing mailed to the Company and to each transfer
         agent of the Common Shares or Preferred shares by registered or
         certified mail and to the holders of the Right Certificates by
         first-class mail. The Company may remove the Rights Agent or any
         successor Rights Agent upon 30 days' notice in writing mailed to the
         Rights Agent or successor Rights Agent, as the case may be, and to each
         transfer agent of the Common Shares or Preferred Shares by registered
         or certified mail, and to the holders of the Right Certificates by
         first-class mail. If the Rights Agent shall resign or be removed or
         shall otherwise become incapable of acting, the Company shall appoint a
         successor to the Rights Agent. If the Company shall fail to make such
         appointment within a period of 30 days after giving notice of such
         removal or after it has been notified in writing of such resignation or
         incapacity by the resigning or incapacitated rights Agent or by the
         holder of a Right Certificate (who shall, with such notice, submit such
         holder's Right Certificate for inspection by the Company), then the
         registered holder of any Right Certificate may apply to any court of
         competent jurisdiction for the appointment of a new Rights Agent. Any
         successor Rights Agent whether appointed by the Company or by such a
         court, shall be a corporation or trust company organized and doing
         business under the laws of the United States, in good standing, which
         is authorized under such laws to exercise corporate trust or stock
         transfer powers and is subject to supervision or examination by federal
         or state authority and which has individually or combined with an
         affiliate at the time of its appointment as Rights Agent a combined
         capital and surplus of at least $100 million dollars. After
         appointment, the successor Rights Agent shall be vested with the same
         powers, rights, duties and responsibilities as if it had been
         originally named as Rights Agent without further act or deed; but the
         predecessor Rights Agent shall deliver and transfer to the successor
         Rights Agent any property at the time held by it hereunder, and execute
         and deliver any further assurance, conveyance, act or deed necessary
         for the purpose. Not later than the effective date of any such
         appointment the Company shall file notice

<PAGE>

         thereof in writing with the predecessor Rights Agent and each transfer
         agent of the Common Shares or Preferred Shares, and mail a notice
         thereof in writing to the registered holders of the Right Certificates.
         Failure to give any notice provided for in this Section 21, however, or
         any defect therein, shall not affect the legality or validity of the
         resignation or removal of the Rights Agent or the appointment of the
         successor Rights Agent, as the case may be.

4.       Except as amended hereby, the Agreement and all schedules or exhibits
         thereto shall remain in full force and effect.

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be executed
in their names and on their behalf by and through their duly authorized
officers, as of this 16th day of August, 2001.

                          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.
