the balance of unpaid and accrued interest and other amounts payable hereunder,
shall be due and payable on demand.

The following is a statement of the rights of the Holder and the conditions to
which this Note is subject, and to which the Holder hereof, by the acceptance of
this Note, agrees

1. Default. The Company will be deemed to be in default hereunder and the unpaid
   principal balance of this Note, together with all accrued interest thereon,
   will become immediately due and payable on any default under this Note or the
   Agreement, including without limitation, any breach of the covenants and
   undertakings of the Company thereunder.

2. Successors and Assigns. The rights and obligations of Company and the Holder
   of this Note shall be binding upon and benefit the successors, assigns,
   heirs, administrators and transferees of the parties.

3. Waiver and Amendment. Any provision of this Note may be amended, waived or
   modified upon the written consent of Company and the Holder.

4. Notices. Any notice, approval, request, authorization, direction or other
   communication under this Note shall be given in writing and shall be deemed
   to have been delivered and given for all purposes (i) on the delivery date if
   delivered personally to the party to whom the same is directed or transmitted
   by facsimile with confirmation of receipt, (ii) one (1) business day after

   this Note shall be governed by and construed in accordance with the laws of

8. Miscellaneous.

   (a) The Company hereby waives presentment, demand, protest, notice of
       dishonor, diligence and all other notices, any release or discharge
       arising from any extension of time, discharge of a prior party, release
       of any or all of any security given from time to time for this Note, or
       other cause of release or discharge other than actual payment in full
       hereof.

   (b) The Holder shall not be deemed, by any act or omission, to have waived
       any of its rights or remedies hereunder unless such waiver is in writing
       and signed by the Holder and then only to the extent specifically set
       forth in such writing. A waiver with reference to one event shall not be
       construed as continuing or as a bar to or waiver of any right or remedy
       as to a subsequent event. No delay or omission of the Holder to exercise
       any right, whether before or after a default hereunder, shall impair any
       such right or shall be construed to be a waiver of any right or default,
       and the acceptance at any time by the Holder of any past-due amount shall
       not be deemed to be a waiver of the right to require prompt payment when
       due of any other amounts then or thereafter due and payable.

   (c) Time is of the essence hereof. Upon any default hereunder, the Holder may
       exercise all rights and remedies provided for herein and by law or
       equity, including, but not limited to, the right to immediate payment in

       them, or in law or in equity, shall be cumulative and concurrent, and may
       be pursued singularly, successively or together at the Holder sole
       discretion, and may be exercised as often as occasion therefor shall
       occur.

   (e) The Company and the Holder intend to contract in compliance with all
       state and federal usury laws governing this Note. The Company and the
       Holder agree that none of the terms of the Agreement or this Note shall
       be construed as a contract for, or requirement to pay interest at a rate
       in excess of, the maximum interest rate allowed by any applicable state
       or federal usury laws. If the Holder receives sums which constitute
       interest that would otherwise increase the effective interest rate on the
       Note to a rate in excess of that permitted by any applicable law, then
       all such sums constituting interest in excess of the maximum lawful rate
       shall, at Holder's option, either be credited to the payment of principal
       or returned to the Company.

       IN WITNESS WHEREOF, Company has caused this Note to be issued as of the
date first written above.

                                            COMPUTER MOTION, INC.,

THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR
HYPOTHECATED UNLESS PURSUANT TO SEC RULE 144 OR THERE IS AN EFFECTIVE
REGISTRATION STATEMENT UNDER THE SECURITIES ACT COVERING SUCH SECURITIES OR THE
COMPANY RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES
REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS
DELIVERY REQUIREMENTS OF THE SECURITIES ACT.

                   REDEEMABLE WARRANT TO PURCHASE COMMON STOCK
                            OF COMPUTER MOTION, INC.

         This certifies that (First Name) (Last Name) (the "Holder") and the
Holder's registered successors and assigns are entitled, subject to the terms
and conditions set forth below, to subscribe for and purchase from Computer
Motion, Inc., a Delaware corporation, (the "Company") [____ (Shares) ____ ]
shares of the Common Stock of the Company (the "Warrant Shares").

         The initial "Exercise Price" per Warrant Share shall be Nine Dollars
and Seventeen Cents ($9.17) per share. The Exercise Price and the number and
character of the Warrant Shares are subject to adjustment as provided herein.
The term "Warrant Shares" as used herein includes the shares of the Company's
Common Stock (and such other securities of property into which such shares of
Common Stock may hereafter be changed) which are at the time receivable by the
Holder upon exercise of this Warrant. This Warrant is redeemable by the Company
as set forth in Section 3 hereof. The term "Warrant" as used herein shall
include this Warrant and any Warrant delivered in substitution or exchange
herefor, as provided herein.

         1. Exercise and Expiration.

            1.1 Exercisability of Warrant. This Warrant may be exercised in full
or in part at any time, or from time to time, after the date hereof.

            1.2 Expiration of Warrant; Method of Exercise. This Warrant must be
exercised, if at all, prior to September 22, 2005, at which time this Warrant
shall expire. This Warrant shall be exercised by surrender hereof together with
delivery of a signed Exercise Agreement in the form attached hereto as Annex I
specifying the number of shares to be purchased, together with payment of the
purchase price for the shares to be purchased. As soon as practicable after each
such exercise of this Warrant, the Company shall issue and deliver to the Holder
a certificate or certificates for the Warrant Shares issuable upon such
exercise, registered in the name of the Holder or its designee. If this Warrant
should be exercised in part only, the Company shall, upon surrender of this
Warrant for cancellation, execute and deliver a new Warrant evidencing the right
of the Holder to purchase the balance of the Warrant Shares (or portions
thereof) subject to

<PAGE>   2
purchase hereunder.

         2. Adjustment of Exercise Price and Number of Shares.

         The Exercise Price and the number of shares purchasable upon the
exercise of this Warrant shall be subject to adjustment from time to time upon
the occurrence of certain events described in this Section 2.

            2.1 Stock Dividends, Splits. If the Company shall (i) pay a dividend
or make a distribution in shares of capital stock (whether shares of Common
Stock or capital stock of any other class), (ii) effect a stock split or
subdivide its outstanding Common Stock, (iii) effect a reverse stock split or
combine its outstanding Common Stock into a smaller number of shares, or (iv)
effect any other reclassification or recapitalization, the Exercise Price in
effect immediately prior thereto shall be adjusted so that upon the subsequent
exercise of this Warrant the Holder hereof shall be entitled to receive the
number of shares of capital stock of the Company which the Holder hereof would
have owned or have been entitled to receive after the happening of any of the
events described above had such Warrant been exercised immediately prior to the
happening of such event. An adjustment made pursuant to this Section 2.1 shall
become effective immediately after the record date for any event requiring such
adjustment or shall become effective immediately after the effective date of
such event if no record date is set.

            2.2 Distribution of Assets. In case the Company shall distribute to
all holders of its Common Stock evidences of its indebtedness or assets
(excluding cash dividends or distributions paid from retained earnings of the
Company in respect of its Common Stock), then in each such case the Exercise
Price shall be adjusted so that the Exercise Price shall equal the price
determined by multiplying the Exercise Price in effect immediately prior to the
record date for such distribution by a fraction of which the numerator shall be
the then current market price per share (as defined in Section 2.3 below) of the
Common Stock on the record date for such event less the then fair market value
(as determined by the Board of Directors of the Company, whose determination, if
reasonable, shall be conclusive) of the portion of the assets or evidences of
indebtedness so distributed applicable to one share of the Common Stock
outstanding as of such record date, and the denominator shall be the then
current market price per share (as defined in Section 2.3 below) of the Common
Stock. Such adjustment shall become effective immediately after the record date
for the determination of shareholders entitled to receive such distribution.

            2.3 Definitions. For the purposes of any computation under Section
2.2 above:

                (a) The current market price per share on any record date or
other date for determination of value shall be deemed to be the average of the
closing price per share on the ten (10) trading days before such record or
determination date. For the purpose of all relevant provisions of this Warrant,
the closing price for each day shall be the last reported sale price as reported
by NASDAQ, or if no such sales are then being reported, the average of the
highest reported bid and lowest reported asked prices as furnished by the
National Association of Securities Dealers, Inc., through NASDAQ or another
organization if NASDAQ is no longer reporting such information. If no price is
determinable as described above for the purposes required herein, the fair value
of such shares, as reasonably determined by the Board of Directors of the
Company, shall be used.

                                       2

<PAGE>   3

                (b) Shares outstanding shall mean the aggregate of all shares of
Common Stock of the Company outstanding and all shares of Common Stock issuable
upon the exercise of all outstanding rights, warrants or options to subscribe
for or purchase Common Stock (or securities convertible into Common Stock) and
the conversion of all outstanding indebtedness or equity securities convertible
into or exchangeable for shares of Common Stock.

            2.4 De Minimis Change. No adjustment in the Exercise Price shall be
required unless such adjustment would require an increase or decrease of at
least one cent ($0.01) in such price; provided, however, that any adjustments
which by reason of this Section 2.5 are not required to be made shall be carried
forward and taken into account in any subsequent adjustment. All calculations
under this Section 2 shall be made to the nearest cent or to the nearest
one-hundredth of a share, as the case may be. Anything in this Section 2 to the
contrary notwithstanding, the Company shall be entitled to make such reductions
in the Exercise Price, in addition to those required by this Section 2, as it in
its discretion shall determine to be advisable.

            2.5 Adjustment of Warrant Shares. Upon each adjustment of the
Exercise Price pursuant to this Section 2, the holder of this Warrant shall
thereafter be entitled to purchase, at the Exercise Price resulting from such
adjustment, the number of Warrant Shares obtained by multiplying the Exercise
Price in effect immediately prior to such adjustment by the number of Warrant
Shares purchasable pursuant hereto immediately prior to such adjustment; and
dividing the product thereof by the Exercise Price resulting from such
adjustment.

            2.6 Notice. Whenever the Exercise Price is adjusted, as herein
provided, the Company shall promptly prepare a notice of such adjustment of the
Exercise Price setting forth the adjusted Exercise Price, the number of shares
issuable upon exercise of the Warrant and the date on which such adjustment
becomes effective and shall mail such notice of such adjustment of the Exercise
Price to the holder of this Warrant at the address of such Holder as in the
records of the Company.

            2.7 Deferrals. In any case in which this Section 2 provides that an
adjustment shall become effective immediately after a record date for an event,
the Company may elect to defer until the occurrence of such event (i) issuing to
the Holder of this Warrant exercised after such record date and before the
occurrence of such event the additional shares of Common Stock issuable upon
such exercise before giving effect to such adjustment and (ii) paying to the
Holder any amount in cash in lieu of any fractional share.

<PAGE>   4

            2.8 Effect of Reclassification, Consolidation, Merger or Sale. If
any of the following events occur, namely (i) any reclassification or change of
outstanding shares of Common Stock issuable upon exercise of this Warrant (other
than a change in par value, or from par value to no par value, or from no par
value to par value, or as a result of a subdivision or combination), (ii) any
consolidation or merger to which the Company is a party other than a
consolidation or merger in which the Company is the continuing corporation and
which does not result in any reclassification or change (other than a change in
par value, or from par value to no par value, or from no par value to par value,
or as a result of a subdivision or combination) in, outstanding shares of Common
Stock, or (iii) any sale or conveyance of the properties and assets of the
Company as, or substantially as, an entirety; then the Company or such successor
or purchaser, as the case may be, shall execute a new Warrant providing that the
new Warrant shall be convertible only into the kind and amount of shares of
stock and other securities, cash or property receivable upon such
reclassification, change, consolidation, merger, sale or conveyance by a holder
of the number of shares of Common Stock issuable upon conversion of such Warrant
immediately prior to such reclassification, change, consolidation, merger, sale
or conveyance. The above provisions of this Section shall similarly apply to
successive reclassifications, consolidations, mergers and sales.

            2.9 No Impairment. The Company will not, by amendment of its
Articles of Incorporation or through any consolidation, merger, reorganization,
transfer of assets, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms herein, but will at all times in good faith assist in the carrying out
of all such terms and in the taking of all such actions as may be necessary or
appropriate in order to protect the rights of the Holder of this Warrant against
dilution or other impairment.

         3. Call of Warrants. The Company may, at its option, at any time a
public trading market for the Company's Common Stock exists, upon not less than
15 days' nor more than 60 days' notice, call for redemption of all or any
portion of the then outstanding Warrant at a call price of $.05 per underlying
Warrant Share (such price is hereinafter referred to as the "Call Price"), at
any time, provided the average of the closing of the Company's Common Stock, as
determined pursuant to Section 2.3(a) above, has been at least 200% of the then
effective Exercise Price of the Warrant, for 20 consecutive business days ending
within 15 days of the date of the notice of such call shall have been given to
the Warrant holder by the Company. In the event the Company exercises its right
to redeem the Warrant, such Warrant will be exercisable until the close of
business on the date fixed for redemption in such notice. If any Warrant called
for redemption is not exercised by such time, such Warrant shall cease to be
exercisable and the holder thereof shall be entitled only to the redemption
price.

         4. Registration Rights.

            4.1 Registration of Shares. Within 18 months from the date of this
Warrant, the Company shall prepare and file with the Securities and Exchange
Commission (the "SEC") a registration statement (such registration statement
including the prospectus, amendments and supplements to such registration
statement or prospectus, including pre- and post-effective amendments, all
exhibits thereto, and all material incorporated by reference or deemed to be
incorporated by reference in such registration statement, a "Registration
Statement") covering all of the Warrant Shares for an offering to be made on a
continuous basis pursuant to Rule 415

                                       4

<PAGE>   5

promulgated under the Securities Act of 1933, as amended (the "Securities Act").
The Registration Statement shall be on Form S-3 (except if the Company is not
then eligible to register for resale the Warrant Shares on Form S-3, such
registration shall be on another appropriate form). The Company shall use its
reasonable best efforts to cause the Registration Statement to be declared
effective under the Securities Act until the date which is two years after the
date the such Registration Statement is declared effective by the SEC or such
earlier date when all Warrant Shares covered by such Registration Statement (the
"Registrable Securities") have been sold or may be sold without volume
restrictions pursuant to Rule 144(k) promulgated under the Securities Act as
determined by counsel to the Company pursuant to a written opinion letter to
such effect (the "Effective Period").

            4.2 Information by Holder. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 4 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding the Holder, the
Registrable Securities held by the Holder, and the intended method of
disposition of such securities as shall be required to effect the registration
of such Holder's Registrable Securities.

            4.3 Expense. The Company shall bear all costs and expenses in
connection with and registrations, filings or qualifications pursuant to a
registration effectuated under this Section 4, including, but not limited to,
printing, legal and accounting expenses, SEC filing fees and "blue sky" fees and
expenses (including reasonable fees and disbursements of counsel for the Company
in its capacity as counsel to the selling Holders hereunder; provided, however,
if Company counsel does not make itself available for this purpose, the Company
will pay the reasonable fees and disbursements of one special counsel for the
selling Holders selected by them); provided, however, that the Company shall
have no obligation to pay or otherwise bear (i) any portion of the underwriter's
commissions or discounts or stock transfer taxes attributable to the Registrable
Securities being offered and sold by the Holders of Registrable Securities, or
(ii) any of such expenses if the payment of such expenses by the Company is
prohibited by the laws of a state in which such offering is qualified and only
to the extent so prohibited.

         5. Transfer of Warrant. This Warrant shall be registered on the books
of the Company and shall be transferable in whole or in part on such books by
the registered Holder hereof in person or by duly authorized attorney. Unless
and until this Warrant and the Warrant Shares are registered under the
Securities Act of 1933 (the "Securities Act"), this Warrant and any certificate
for Warrant Shares issued or issuable upon exercise of this Warrant shall
contain a legend on the face thereof, in form and substance satisfactory to
counsel for the Company, stating that this Warrant and the Warrant Shares may
not be sold, transferred or otherwise disposed of unless, in the opinion of
counsel satisfactory to the Company, the Warrant or the Warrant Shares may be
transferred without such registration. This Warrant and the Warrant Shares may
also be subject to restrictions on transferability under applicable state
securities or blue sky laws. Until this Warrant and the Warrant Shares are
registered under the Securities Act, the Company may require, as a condition of
transfer of this Warrant or the Warrant Shares that the transferee (who may be
the Holder in the case of an exercise or exchange) represent that the securities
being transferred are being acquired for investment purposes and for the
transferee's own account and not with a view to or for sale in connection with
any distribution of the security. The Company may also require that transferee
provide written information adequate to establish that the transferee is an
"accredited investor" within the meaning of Regulation D issued under the
Securities Act, and otherwise meets all qualifications necessary to comply with
exemptions to any applicable state securities and Blue Sky laws, all as
determined by counsel to the Company.

                                       5

         6. Reservation of Common Stock. The Company hereby covenants and agrees
that it shall at all times reserve and keep authorized and available for
issuance, free of any preemptive rights or rights of first refusal, a sufficient
number of Warrant Shares for the purpose of issuance upon exercise of this
Warrant to permit the exercise of this Warrant in whole.

         IN WITNESS WHEREOF, the Company has caused this Warrant to be duly
executed and delivered by its duly authorized officers as of the 22nd day of
September, 2000.
