                                   ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

The Company represents and warrants to the Investor that, except as set forth on
the Schedule of Exceptions attached hereto:

Section 4.1.   Organization of the Company. The Company is a corporation duly
incorporated and existing in good standing under the laws of the State of
Delaware and has all requisite corporate authority to own its properties and to
carry on its business as now being conducted as described in the Company's SEC
Documents. The Company does not have any subsidiaries and does not own more that
fifty percent (50%) of or control any other business entity, except as set forth
in the SEC Documents. The Company is duly qualified as a foreign corporation to
do business and is in good standing in every jurisdiction in which the nature of
the business conducted or property owned by it makes such qualification
necessary, other than those in which the failure so to qualify could not
reasonably be expected to have a Material Adverse Effect.

Section 4.2.   Authority. (i) The Company has the requisite corporate power and
authority to enter into and perform its obligations under this Agreement, the
Registration Rights Agreement and the Warrant and to issue the Preferred Stock,
the Conversion Shares, the Warrant and the Warrant Shares, (ii) the execution,
issuance and delivery of this Agreement, the Registration Rights Agreement and
the Warrant by the Company and the consummation by it of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
and no further consent or authorization of the Company or its Board of Directors
or stockholders is required, and (iii) this Agreement, the Registration Rights
Agreement and the Warrant have been duly executed and delivered by the Company
and constitute valid and binding obligations of the Company enforceable against
the Company in accordance with their terms, except as such enforceability may be
limited by applicable bankruptcy, insolvency, or similar laws relating to, or
affecting generally the enforcement of, creditors' rights and remedies or by
other equitable principles of general application. The Company has duly and
validly authorized and reserved for issuance shares of Common Stock sufficient
in number for the conversion of 2,000 shares of Preferred Stock and for the
exercise of the Warrants. The Company understands and acknowledges the
potentially dilutive effect to the Common Stock of the issuance of the
Conversion Shares and the Warrant Shares. The

                                       7
<PAGE>   8

Company further acknowledges that its obligation to issue Conversion Shares upon
conversion of the Preferred Stock and Warrant Shares upon exercise of the
Warrants in accordance with this Agreement and the Certificate of Designations
is absolute and unconditional regardless of the dilutive effect that such
issuance may have on the ownership interests of other stockholders of the
Company and notwithstanding the commencement of any case under 11 U.S.C. Section
101 et seq. (the "Bankruptcy Code"). In the event the Company is a debtor under
the Bankruptcy Code, the Company hereby waives to the fullest extent permitted
any rights to relief it may have under 11 U.S.C. Section 362 in respect of the
conversion of the Preferred Stock and the exercise of the Warrants. The Company
agrees, without cost or expense to the Investor, to take or consent to any and
all action necessary to effectuate relief under 11 U.S.C. Section 362.

Section 4.3.   Capitalization. The authorized capital stock of the Company
consists of 50,000,000 shares of Common Stock, par value $0.01, of which
14,291,915 were issued and outstanding as of December 31, 1999, and 1,000,000
shares of Preferred Stock, par value $0.01, of which 1,725 shares of Series D
Convertible Preferred Stock and 1,200 shares of Series E Convertible Preferred
Stock were issued and outstanding as of December 31, 1999, and 2,000 shares of
Preferred Stock have been properly designated as Series F Convertible Preferred
Stock. Except as set forth in the SEC Documents, there are no outstanding
Capital Shares Equivalents. All of the outstanding shares of Common Stock of the
Company have been duly and validly authorized and issued and are fully paid and
non-assessable.

Section 4.4.   Common Stock. The Company has registered its Common Stock
pursuant to Section 12(b) or (g) of the Exchange Act and is in full compliance
with all reporting requirements of the Exchange Act, and the Company has
maintained all requirements for the continued listing or quotation of its Common
Stock, and such Common Stock is currently listed or quoted on the Principal
Market. As of the date hereof, the Principal Market is The Nasdaq SmallCap
Market and the Company has not received any notice regarding, and to its
knowledge there is no threat, of the termination or discontinuance of the
eligibility of the Common Stock for such listing.

Section 4.5.   SEC Documents. The Company has delivered or made available to the
Investor true and complete copies of the SEC Documents. The Company has not
provided to the Investor any information that, according to applicable law, rule
or regulation, should have been disclosed publicly prior to the date hereof by
the Company, but which has not been so disclosed. As of their respective dates,
the SEC Documents complied in all material respects with the requirements of the
Exchange Act, and rules and regulations of the SEC promulgated thereunder and
the SEC Documents did not contain any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. The financial statements of the Company included
in the SEC Documents complied in all material respects with applicable
accounting requirements and the published rules and regulations of the SEC or
other applicable rules and regulations with respect thereto. Such financial
statements have been prepared in accordance with generally accepted accounting
principles applied on a consistent basis during the periods involved (except (i)
as may be otherwise indicated in such financial statements or the notes thereto
or (ii) as set forth in Section

                                       8

4.5 to the Schedule of Exceptions) and fairly present in all material respects
the financial position of the Company as of the dates thereof and the results of
operations and cash flows for the periods then ended. Neither the Company nor
any of its subsidiaries has any indebtedness, obligations or liabilities of any
kind (whether accrued, absolute, contingent or otherwise, and whether due or to
become due) that would have been required to be reflected in, reserved against
or otherwise described in the financial statements or in the notes thereto in
accordance with GAAP, which was not fully reflected in, reserved against or
otherwise described in the financial statements or the notes thereto or was not
incurred in the ordinary course of business consistent with the Company's past
practices since the late date of the financial statements.

Section 4.6.   Exemption from Registration; Valid Issuances. The sale of the
Preferred Stock, the Conversion Shares, the Warrant and the Warrant Shares will
be properly issued pursuant to Rule 4(2), Regulation D and/or any applicable
state securities law. When issued, the Preferred Stock, the Conversion Shares
and the Warrant Shares will be duly and validly issued, fully paid, and
non-assessable. Neither the sales of the Preferred Stock, the Conversion Shares,
the Warrant or the Warrant Shares pursuant to, nor the Company's performance of
its obligations under, this Agreement, the Registration Rights Agreement or the
Warrant will (i) result in the creation or imposition by the Company of any
liens, charges, claims or other encumbrances upon the Preferred Stock, the
Conversion Shares, the Warrant Shares or any of the assets of the Company, or
(ii) entitle the holders of Outstanding Capital Shares to preemptive or other
rights to subscribe to or acquire the Capital Shares or other securities of the
Company. The Preferred Stock, the Conversion Shares, and the Warrant Shares
shall not subject the Investor to personal liability by reason of the possession
thereof.

Section 4.7.   No General Solicitation or Advertising in Regard to this
Transaction. Neither the Company nor any of its affiliates nor any distributor
or any person acting on its or their behalf (i) has conducted or will conduct
any general solicitation (as that term is used in Rule 502(c) of Regulation D)
or general advertising with respect to any of the Preferred Stock, the
Conversion Shares, the Warrant or the Warrant Shares, or (ii) made any offers or
sales of any security or solicited any offers to buy any security under any
circumstances that would require registration of the Preferred Stock, the
Conversion Shares, the Warrant or the Warrant Shares under the Securities Act.

Section 4.8.   Corporate Documents. The Company has furnished or made available
to the Investor true and correct copies of the Company's Restated Certificate of
Incorporation, as amended and in effect on the date hereof, and the Company's
By-Laws, as amended and in effect on the date hereof.

Section 4.9.   No Conflicts. The execution, delivery and performance of this
Agreement by the Company and the consummation by the Company of the transactions
contemplated hereby, including without limitation the issuance of the Preferred
Stock, the Conversion Shares, the Warrant and the Warrant Shares, do not and
will not (i) result in a violation of the Company's Restated Certificate of
Incorporation or By-Laws, each as amended and in effect as of the date hereof,
or (ii) conflict with, or constitute a material default (or an event that with
notice or lapse of time or both would become a default) under, or give to others
any rights of termination, amendment, acceleration or

                                       9
<PAGE>   10

cancellation of, any material agreement, indenture, instrument or any "lock-up"
or similar provision of any underwriting or similar agreement to which the
Company is a party, or (iii) result in a violation of any federal, state or
local law, rule, regulation, order, judgment or decree (including federal and
state securities laws and regulations) applicable to the Company or by which any
property or asset of the Company is bound or affected (except for such
conflicts, defaults, terminations, amendments, accelerations, cancellations and
violations as could not reasonably be expected to have, individually or in the
aggregate, a Material Adverse Effect) nor is the Company otherwise in violation
of, conflict with or in default under any of the foregoing. The business of the
Company is not being conducted in violation of any law, ordinance or regulation
of any governmental entity, except for possible violations that either singly or
in the aggregate could not reasonably be expected to have a Material Adverse
Effect. The Company is not required under federal, state or local law, rule or
regulation to obtain any consent, authorization or order of, or make any filing
or registration with, any court or governmental agency in order for it to
execute, deliver or perform any of its obligations under this Agreement or issue
and sell the Preferred Stock or the Warrant in accordance with the terms hereof
(other than any SEC, NASD, The Nasdaq Stock Market Inc., or state securities
filings that may be required to be made by the Company subsequent to any
Closing, any registration statement that may be filed pursuant hereto, and any
shareholder approval required by the rules applicable to companies whose common
stock trades on The Nasdaq SmallCap Market); provided that, for purposes of the
representation made in this sentence, the Company is assuming and relying upon
the accuracy of the relevant representations and agreements of the Investor

an Event of Default (as so defined), has occurred and is continuing which could
have a Material Adverse Effect.

Section 4.11.  No Undisclosed Liabilities. The Company has no liabilities or
obligations which are material, individually or in the aggregate, and are not
disclosed in the SEC Documents or otherwise publicly announced, other than those
incurred in the ordinary course of the Company's business since January 1, 1999,
and which, individually or in the aggregate, could not reasonably be expected to
have a Material Adverse Effect.

Section 4.12.  No Undisclosed Events or Circumstances. Since January 1, 1999 no
event or circumstance has occurred or exists with respect to the Company or its

next preceding the date hereof, and the Company shall not permit any of its
directors, officers or Affiliates directly or indirectly to take, any action
(including, without limitation, any offering or sale to any person or entity of

unavailable the exemption from Securities Act registration being relied upon by
the Company for the offer and sale to Investor of the Preferred Stock (and the
Conversion Shares) or the Warrants (and the Warrant Shares) as contemplated by
this Agreement. No form of general solicitation or advertising has been used or

far as is known by the Company, requested of any court, arbitrator or
governmental agency which might result in a Material Adverse Effect.

Common Stock traded on any other Principal Market, it will include in such
application the Conversion Shares and the Warrant Shares, and will take such
other action as is necessary or desirable in the opinion of the investor to

each of the Company and Investor in this Agreement, the annexes, schedules and

               1.     any misrepresentation, omission of fact or breach of any

<PAGE>   21

               2.     any failure by the Company to perform in any material
         respect any of its covenants, agreements, undertakings or obligations
         set forth in this Agreement, the annexes, schedules or exhibits hereto
         or any instrument, agreement or certificate entered into or delivered
         by the Company pursuant to this Agreement; or

               3.     any litigation directly against the Investor by
         non-affiliates of the Company relating to this Agreement
         and the transactions contemplated hereby.

               Investor hereby agrees to indemnify and hold harmless the
Company, its Affiliates and their respective officers, directors, partners and

Losses, and agrees to reimburse the Company Indemnitees for all out-of-pocket
expenses (including the fees and expenses of legal counsel and the cost of any
investigation and preparation), in each case promptly as incurred by the Company
Indemnitees and to the extent arising out of or in connection with:

               1.     any misrepresentation, omission of fact, or breach of any
of Investor's representations or warranties contained in this Agreement, the
annexes, schedules or exhibits hereto or any instrument, agreement or
certificate entered into or delivered by Investor pursuant to this Agreement; or

               2.     any failure by Investor to perform in any material respect
any of its covenants, agreements, undertakings or obligations set forth in this
Agreement or any instrument, certificate or agreement entered into or delivered
by Investor pursuant to this Agreement.

Section 7.3.   Notice. Promptly after receipt by either party hereto seeking
indemnification pursuant to Section 7.2 (an "Indemnified Party") of written
notice of any investigation, claim, proceeding or other action in respect of
which indemnification is being sought (each, a "Claim"), the Indemnified Party
promptly shall notify the party against whom indemnification pursuant to Section
7.2 is being sought (the "Indemnifying Party") of the commencement thereof; but
the omission to so notify the Indemnifying Party shall not relieve it from any
liability that it otherwise may have to the Indemnified Party, except to the
extent that the Indemnifying Party is materially prejudiced and forfeits
substantive rights and defenses by reason of such failure. In connection with
any Claim as to which both the Indemnifying Party and the Indemnified Party are
parties, the Indemnifying Party shall be entitled to assume the defense thereof.
Notwithstanding the assumption of the defense of any Claim by the Indemnifying
Party, the Indemnified Party shall have the right to employ separate legal
counsel and to participate in the defense of such Claim, and the Indemnifying
Party shall bear the reasonable fees, out-of-pocket costs and expenses of such
separate legal counsel to the Indemnified Party if (and only if): (x) the
Indemnifying Party shall have agreed to pay such fees, out-of-pocket costs and
expenses, (y) the Indemnified Party and the Indemnifying Party reasonably shall
have concluded that representation of the Indemnified Party and the Indemnifying
Party by the same legal counsel would not be appropriate due to actual or, as
reasonably determined by legal counsel to the Indemnified Party, potentially
differing interests between such parties in the conduct of the defense of such
Claim, or if there may be legal defenses

                                       21
<PAGE>   22

available to the Indemnified Party that are in addition to or disparate from
those available to the Indemnifying Party, or (z) the Indemnifying Party shall
have failed to employ legal counsel reasonably satisfactory to the Indemnified
Party within a reasonable period of time after notice of the commencement of
such Claim. If the Indemnified Party employs separate legal counsel in
circumstances other than as described in clauses (x), (y) or (z) above, the
fees, costs and expenses of such legal counsel shall be borne exclusively by the
Indemnified Party. Except as provided above, the Indemnifying Party shall not,
in connection with any Claim in the same jurisdiction, be liable for the fees
and expenses of more than one firm of legal counsel for the Indemnified Party
(together with appropriate local counsel). The Indemnifying Party shall not,
without the prior written consent of the Indemnified Party (which consent shall
not unreasonably be withheld), settle or compromise any Claim or consent to the
entry of any judgment that does not include an unconditional release of the
Indemnified Party from all liabilities with respect to such Claim or judgment.

Section 7.4.   Direct Claims. In the event one party hereunder should have a
claim for indemnification that does not involve a claim or demand being asserted
by a third party, the Indemnified Party promptly shall deliver notice of such
claim to the Indemnifying Party. If the Indemnified Party disputes the claim,
such dispute shall be resolved by mutual agreement of the Indemnified Party and
the Indemnifying Party.

disposition of the Registrable Securities on behalf of the Investor pursuant to
the Registration Statement, any such registration statement or amendment or
supplement thereto or any blue sky, NASD or other filing, all SEC Documents and
other filings with the SEC, and all other publicly available corporate documents
and properties of the Company as may be reasonably necessary for the purpose of
such review, an d cause the Company's officers, directors and employees to
supply all such publicly available information reasonably requested by the
Investor or any such representative, advisor or underwriter in connection with
such Registration Statement (including, without limitation, in response to all
questions and other inquiries reasonably made or submitted by any of them),
prior to and from time to time after the filing and effectiveness of the
Registration Statement for the sole purpose of enabling the Investor and such
representatives, advisors and underwriters and their respective accountants and
attorneys to conduct initial and ongoing due diligence with respect to the
Company and the accuracy of the Registration Statement.

Section 8.2.   Non-Disclosure of Non-Public Information

         (a)   The Company shall not disclose non-public information to the
Investor, advisors to or representatives of the Investor unless prior to
disclosure of such information the Company identifies such information as being
non-public information and provides the Investor, such advisors and
representatives with the opportunity to accept or refuse to accept such
non-public information for review. Other than disclosure of any comment letters
received from the SEC staff with respect to the Registration Statement, the
Company may, as a condition to disclosing any non-public information hereunder,
require the Investor's advisors and representatives to enter into a
confidentiality agreement in form reasonably satisfactory to the Company and the
Investor.

         (b)   Nothing herein shall require the Company to disclose non-public
information to the Investor or its advisors or representatives, and the Company
represents that it does not disseminate non-public information to any investors
who purchase stock in the Company in a public offering, to money managers or to
securities analysts, provided, however, that notwithstanding anything herein to
the contrary, the Company will, as hereinabove provided, immediately notify the
advisors and representatives of the Investor and, if any, underwriters, of any
event or the existence of any circumstance (without any obligation to disclose
the specific event or circumstance) of which it becomes aware, constituting
non-public information (whether or not requested of the Company specifically or
generally during the course of due diligence by such persons or entities),
which, if not disclosed in the prospectus included in the Registration Statement
would cause such prospectus to include a material misstatement or to omit a
material fact required to be stated therein in order to make the statements,
therein in light of the circumstances in which they were made, not misleading.
Nothing contained in this Section 8.2 shall be construed to mean that such
persons or entities other than the Investor (without the written consent of the
Investor prior to disclosure of such information) may not obtain non-public
information in the course of conducting due diligence in accordance with the
terms of this Agreement and nothing herein shall prevent any such persons or
entities from notifying the Company of their opinion that based on such due
diligence by such persons or entities, that the Registration Statement contains
an untrue statement of a material fact or omits a material fact required to be
stated in the Registration Statement or necessary to make the statements
contained therein, in light of the circumstances in which they were made, not
misleading.

                        INTEGRATED SURGICAL SYSTEMS, INC.

                     PURSUANT TO SECTION 151 OF THE DELAWARE

                             GENERAL CORPORATION LAW

               Integrated Surgical Systems, Inc., a corporation organized and
existing under and by virtue of the General Corporation Law of the State of
Delaware (hereinafter the "Corporation"), in accordance with the provisions of
Section 151(g) thereof, DOES HEREBY CERTIFY that at a meeting of the Board of
Directors of the Corporation duly held on January 24, 2000:

         FIRST: The following resolution was duly adopted by the Board of
Directors of the Corporation:

         "RESOLVED: That pursuant to the authority vested in the Board of
Directors of the Corporation by Article 4 of the Corporation's restated
certificate of incorporation, as amended (the "Certificate of Incorporation"), a
series of Preferred Stock of the Corporation be, and it hereby is, created out
of the authorized but unissued shares of the capital stock of the Corporation,
such series to be designated Series F Convertible Preferred Stock (the "Series F
Convertible Preferred Stock"), to consist of 2,000 shares, par value $0.01 per
share, of which the preferences and relative and other rights, and the
qualifications, limitations or restrictions thereof, shall be as set forth in
the Certificate of Designations annexed hereto:

         1.    NUMBER OF SHARES OF SERIES F CONVERTIBLE PREFERRED STOCK. Of the
989,730 shares of authorized but unissued Preferred Stock, $0.01 par value
("Preferred Stock") of the Corporation, two thousand (2,000) shares shall be
designated and known as Series F Convertible Preferred Stock, par value $0.01
per share ("Series F Convertible Preferred Stock").

         2.    VOTING.

               (a)    Unless required by law, no holder of any shares of Series
F Convertible Preferred Stock shall be entitled to vote at any meeting of
stockholders of the Corporation (or any written actions of stockholders in lieu
of meetings) with respect to any matters presented to the stockholders of the
Corporation for their action or consideration. Notwithstanding the foregoing,
the Corporation shall provide each holder of record of Series F Convertible
Preferred Stock with timely

                                       1
<PAGE>   31

notice of every meeting of stockholders of the Corporation and shall provide
each holder with copies of all proxy materials distributed in connection
therewith.

               (b)    So long as shares of Series F Convertible Preferred Stock
are outstanding, the Corporation shall not, without first obtaining the approval
(by vote or written consent, as provided by the Delaware General Corporation
Law) of the holders of at least 85% of the then outstanding shares of Series F
Convertible Preferred Stock:

                      (i)     alter or change the rights, preferences or
privileges of the Series F Convertible Preferred  Stock;

                      (ii)    create any new class or series of capital stock
ranking on a parity with ("Pari Passu Securities") or a preference over the
Series F Convertible Preferred Stock as to distribution of assets upon
liquidation, dissolution or winding up of the Corporation ("Senior Securities")
or alter or change the rights, preferences or privileges of any Senior
Securities so as to affect adversely the Series F Convertible Preferred Stock;

                      (iii)   increase the authorized number of shares of Series
F Convertible Preferred Stock; or

                      (iv)    do any act or thing not authorized or contemplated
by this Certificate of Designations which would result in taxation of the
holders of shares of the Series F Convertible Preferred Stock under Section 305
of the Internal Revenue Code of 1986, as amended (or any comparable provision of
the Internal Revenue Code as hereafter from time to time amended).

               In the event holders of at least 85% of the then outstanding
shares of Series F Convertible Preferred Stock agree to allow the Corporation to
alter or change the rights, preferences or privileges of the shares of Series F
Convertible Preferred Stock, pursuant to subsection (b) above, so as to affect
the Series F Convertible Preferred Stock, then the Corporation will deliver
notice of such approved change to the holders of the Series F Convertible
Preferred Stock that did not agree to such alteration or change (the "Dissenting
Holders") and Dissenting Holders shall have the right for a period of thirty
(30) days to convert any and all shares of then held Series F Convertible
Preferred Stock pursuant to the terms of this Certificate of Designations as in
effect prior to such alteration or change, or else to continue to hold their
shares of Series F Convertible Preferred Stock.

         3.    DIVIDENDS

               No holder of any shares of Series F Convertible Preferred Stock
shall be entitled to receive any dividends.

<PAGE>   32

         4.    LIQUIDATION.

               (a)    If the Corporation shall commence a voluntary case under
the Federal bankruptcy laws or any other applicable Federal or state bankruptcy,
insolvency or similar law, or consent to the entry of an order for relief in an
involuntary case under any law or to the appointment of a receiver, liquidator,
assignee, custodian, trustee, sequestrator (or other similar official) of the
Corporation or of any substantial part of its property, or make an assignment
for the benefit of its creditors, or admit in writing its inability to pay its
debts generally as they become due, or if a decree or order for relief in
respect of the Corporation shall be entered by a court having jurisdiction in
the premises in an involuntary case under the Federal bankruptcy laws or any
other applicable Federal or state bankruptcy, insolvency or similar law
resulting in the appointment of a receiver, liquidator, assignee, custodian,
trustee, sequestrator (or other similar official) of the Corporation or of any
substantial part of its property, or ordering the winding up or liquidation of
its affairs, and any such decree or order shall be unstayed and in effect for a
period of thirty (30) consecutive days and, on account of any such event, the
Corporation shall liquidate, dissolve or wind up, or if the Corporation shall
otherwise liquidate, dissolve or wind up (each such event being considered a
"Liquidating Event"), no distribution shall be made to the holders of any shares
of capital stock of the Corporation upon liquidation, dissolution or winding up
unless prior thereto, the holders of shares of Series F Convertible Preferred
Stock shall have received the Liquidation Preference (as defined in Paragraph
4(c)) with respect to each share. If upon the occurrence of a Liquidation Event,
the assets and funds available for distribution among the holders of the Series
F Convertible Preferred Stock and holders of Pari Passu Securities shall be
insufficient to permit the payment to such holders of the preferential amounts
payable thereon, then the entire assets and funds of the Corporation legally
available for distribution to the Series F Convertible Preferred Stock and the
Pari Passu Securities shall be distributed ratably among such shares in
proportion to the ratio that that Liquidation Preference payable on each such
share bears to the aggregate Liquidation Preference payable on all such shares.

               (b)    At the option of each holder of the Series F Convertible
Preferred Stock, the sale, conveyance of disposition of all or substantially all
of the assets of the Corporation, the effectuation by the Corporation of a
transaction or series or related transactions in which more than 50% of the
voting power of the Corporation is disposed of, or the consolidation, merger or
other business combination of the Corporation with or into any other Person or
Persons when the Corporation is not the survivor shall be deemed to be a
liquidation, dissolution or winding up of the Corporation pursuant to which the
Corporation shall be required to distribute, upon consummation of and as a
condition to such transaction an amount equal to the Liquidation Preference with
respect to each outstanding share of Series F Convertible Preferred Stock held
by such Holder in accordance with and subject to the terms of this Article 4.

               (c)    The Liquidation Preference shall be the Stated Value of
$1,000 per share of Series F Convertible Preferred Stock.

               (d)    The Series F Convertible Preferred Stock shall rank on a
parity with the Corporation's Series D Convertible Preferred Stock and Series E
Convertible Preferred Stock as

                                                                               4

to the distribution of the assets of the Corporation upon liquidation,
dissolution or winding up of the Corporation.

         5.    OPTIONAL CONVERSION.  The holders of shares of Series F
Convertible Preferred Stock shall have the following conversion rights:

               (a)    RIGHT TO CONVERT; CONVERSION PRICE. Subject to the terms,
conditions, and restrictions of this Paragraph 5, the holder of any shares of
Series F Convertible Preferred Stock shall have the right to convert each such
share of Series F Convertible Preferred Stock (except that upon any liquidation
of the Corporation, the right of conversion shall terminate at the close of
business on the business day fixed for payment of the amount distributable on
the Series F Convertible Preferred Stock) into a number of shares of Common
Stock equal to the Stated Value of such share or shares of Series F Convertible
Preferred Stock divided by (i) the lowest price at which a trade of the Common
Stock is executed, as reported by Bloomberg L.P., on the principal market for
the Corporation's Common Stock (the "Principal Market") during the period of
five Trading Days ending with the last Trading Day prior to the date of
conversion (the "Market Price"), after (ii) discounting the Market Price by 15%
to determine the conversion price (the "Conversion Price"). To illustrate, if
the Market Price as of the Conversion Date is $1.35 and 100 shares of Series F
Convertible Preferred Stock are being converted, the Stated Value for which
would be $100,000, then the Conversion Price shall be $1.15 per share of Common
Stock ($1.35 x .85), whereupon the Stated Value of $100,000 of Series F
Convertible Preferred Stock would entitle the holder thereof to convert the 100
shares of Series F Convertible Preferred Stock into 86,957 shares of Common
Stock ($100,000 divided by 1.15 equals 86,957). However, in no event shall the
Conversion Price be greater than $1.22 per share of Common Stock (the "Maximum
Conversion Price").The right of each holder to convert shares of Series F
Convertible Preferred Stock into shares of Common Stock is subject to the
limitations set forth in Paragraph 5(b) below, and for the purpose of complying
with the limitation set forth in Paragraph 5(b)(ii), shall be prorated among the
original purchasers of the shares of Series F Convertible Preferred Stock (the
"Initial Purchasers") and their subsequent transferees, if any, based upon the
number of shares of Series F Convertible Preferred Stock purchased by the
Initial Purchasers. In addition, instead of issuing shares of Common Stock upon
conversion, upon prior written notice to the holder, the Corporation may elect
to pay the holder an amount in cash equal to (i) the closing sale price on the
Principal Market on the day prior to the date of conversion (the "Conversion
Date") multiplied by (ii) the number of shares of Common Stock which would
otherwise be issuable to the holder upon such conversion, or any combination of
cash and shares of Common Stock. If notice of the Corporation's election to pay
the holder in cash is not received by the holder prior to the receipt by the
Corporation of a Conversion Notice, the Corporation shall pay the holder in
shares of Common Stock.

               (b)    NUMERICAL LIMITATIONS. (i) No shares of Series F
Convertible Preferred Stock may be converted into Common Stock, to the extent
that, after giving effect to the conversion and issuance of the Common Stock to
be issued pursuant to the applicable Conversion Notice (as defined in Paragraph
5(c) below), the total number of shares of Common Stock deemed beneficially
owned by the holder requesting conversion (other than by virtue of the ownership
of unconverted shares of Series F Convertible Preferred Stock or the ownership
of other securities that have limitations on a holder's rights to exchange,
convert or exercise similar to those limitations set forth herein), together
with all shares of Common Stock deemed beneficially owned by such holder's
Affiliates (as defined in Rule 405 of the Securities Act of 1933, as amended)
that would be aggregated for purposes of determining whether a group under
Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules
promulgated thereunder, would exceed 5% of the total issued and outstanding
shares of Common Stock. If any court of competent jurisdiction shall determine
that the foregoing limitation is ineffective to prevent a holder from being
deemed the beneficial owner of more than 5% of the then outstanding shares of
Common Stock, then the Corporation shall redeem so many of such holder's shares
of Series F Convertible Preferred Stock pursuant to Paragraph 7(a) hereof as are
necessary to cause such holder to be deemed the beneficial owner of not more
than 5% of the then outstanding shares of Common Stock.

                      (ii)    Unless the Corporation shall have obtained the
approval of its voting stockholders to such issuance, if required in accordance
with the rules of the Principal Market, the Corporation shall not issue shares
of Common Stock upon conversion of any shares of Series F Convertible Preferred
Stock if such issuance of Common Stock, when added to the number of shares of
Common Stock previously issued by the Corporation upon conversion of shares of
the Series F Convertible Preferred Stock, together with shares of Common Stock
issued and issuable upon exercise of warrants issued in connection with the sale
of shares of Series F Convertible Preferred Stock, would result in the issuance
of more than 19.9% of the number of shares of Common Stock which were issued and
outstanding on the date upon which the Series F Convertible Preferred Stock was
originally issued (the "Original Issuance Date"). To the extent the number of
shares of Common Stock issuable upon conversion would but for the limitation set
forth in this Paragraph 5(b)(ii) exceed such limit, the Corporation shall redeem
promptly (but not later than the fifth Trading Day after receipt of the
applicable Conversion Notice) the shares of Series F Convertible Preferred Stock
that may not be converted into shares of Common Stock as a result of such
limitation for an amount in cash equal to the greater of (i) $1,500 per share of
Series F Convertible Preferred Stock and (ii) an amount equal to the product of
the closing sale price of a share of Common Stock on the Trading Date
immediately preceding the date of the Conversion Notice and the number of shares
of Common Stock into which such shares of Series F Convertible Preferred Stock
could have been converted but for such limitation on the date of the Conversion
Notice, and the holders of the Series F Convertible Preferred Stock shall be
creditors of the Corporation with respect to that amount.

               (c)    NOTICE OF CONVERSION. The right of conversion shall be
exercised by the holder thereof by giving written notice (the "Conversion
Notice") to the Corporation, by facsimile or by registered mail or overnight
delivery service, with a copy by facsimile to the Corporation's then transfer
agent for its Common Stock, as designated by the Corporation from time to time,
that the holder elects to convert a specified number of shares of Series F
Convertible Preferred Stock representing a specified Stated Value thereof into
Common Stock and, if such conversion will result in the conversion of all of
such holder's shares of Series F Convertible Preferred Stock, by surrender of a
certificate or certificates for the shares so to be converted to the Corporation
at its principal office (or such other office or agency of the Corporation as
the Corporation may designate by notice in writing to the holders of the Series
F Convertible Preferred Stock) at any time during its usual business hours on
the date set forth in the Conversion Notice, together with a statement of the
name or names (with address) in which the certificate or certificates for shares
of Common Stock shall be issued. The Conversion Notice shall include therein the
Stated Value of shares of Series F Convertible Preferred Stock to be converted,
and a calculation (i) of the Market Price, (ii) the Conversion Price, and (iii)
the number of shares of Common Stock to be issued in connection with such
conversion.

               (d)    ISSUANCE OF CERTIFICATES; TIME CONVERSION EFFECTED. (i)
Promptly, but in no event more than three business days, after the receipt of
the Conversion Notice referred to in Subparagraph 5(c) (and surrender of the
certificate or certificates for the share or shares of Series F Convertible
Preferred Stock to be converted within three business days after the receipt of
the Conversion Notice, if requested), the Corporation shall issue and deliver,
or cause to be issued and delivered, to the holder, registered in such name or
names as such holder may direct, a certificate or certificates for the number of
whole shares of Common Stock into which such shares of Series F Convertible
Preferred Stock are converted. To the extent permitted by law, such conversion
shall be deemed to have been effected on the date on which such Conversion
Notice shall have been received by the Corporation and at the time specified
stated in such Conversion Notice, which must be during the calendar day of such
notice, and at such time the rights of the holder of such share or shares of
Series F Convertible Preferred Stock shall cease, and the person or persons in
whose name or names any certificate or certificates for shares of Common Stock
shall be issuable upon such conversion shall be deemed to have become the holder
or holders of record of the shares represented thereby. Issuance of shares of
Common Stock issuable upon conversion which are requested to be registered in a
name other than that of the registered holder shall be subject to compliance
with all applicable federal and state securities laws.

               (ii) The Corporation understands that a delay in the issuance
of the shares of Common Stock beyond three business days could result in
economic loss to the holder. As compensation to the holder for such loss, the
Corporation agrees to pay late payments to the holder for late issuance of
shares of Common Stock upon conversion in accordance with the following schedule
(where "No. Business Days Late" is defined as the number of business days beyond
three (3) business days from the date of receipt of the Conversion Notice):

</TABLE>

The Corporation shall pay any payments incurred under this Paragraph in
immediately available funds upon demand. Nothing herein shall limit holder's
right to pursue injunctive relief and/or actual damages for the Corporation's
failure to issue and deliver Common Stock to the holder. Furthermore, in
addition to any other remedies which may be available to the holder, in the
event that the Corporation fails for any reason to effect delivery of such
shares of Common Stock within five business days the date of receipt of the
Conversion Notice, the holder will be entitled to revoke the relevant Conversion
Notice by delivering a notice to such effect to the Corporation whereupon the
Corporation and the holder shall each be restored to their respective positions
immediately prior to delivery of such Conversion Notice.

                      (iii)   If, at any time (a) the Corporation challenges,
disputes or denies the right of the holder to effect the conversion of the
Series F Convertible Preferred Stock into Common Shares or otherwise dishonors
or rejects any Conversion Notice delivered in accordance with this Paragraph 5
or (b) any third party who is not and has never been an Affiliate of the holder
commences any lawsuit or proceeding or otherwise asserts any claim before any
court or public or governmental authority which seeks to challenge, deny,
enjoin, limit, modify, delay or dispute the right of the holder hereof to effect
the conversion of the Series F Convertible Preferred Stock into Common Stock,
then the holder shall have the right, by written notice to the Corporation, to
require the Corporation to promptly (but not later than the fifth Trading Day
after receipt of such notice) redeem the Series F Convertible Preferred Stock
for cash at a redemption price equal to one hundred thirty-five percent (135%)
of the Stated Value thereof (the "Mandatory Purchase Amount"). Under any of the
circumstances set forth above, the Corporation shall be responsible for the
payment of all costs and expenses of the holder, including reasonable legal fees
and expenses, as and when incurred in disputing any such action or pursuing its
rights hereunder (in addition to any other rights of the holder).

<PAGE>   37

                                                                               8

                      (iv)    The holder shall be entitled to exercise its
conversion privilege notwithstanding the commencement of any case under 11
U.S.C. Section 101 et seq. (the "Bankruptcy Code"). In the event the Corporation
is a debtor under the Bankruptcy Code, the Corporation hereby waives to the
fullest extent permitted any rights to relief it may have under 11 U.S.C.
Section 362 in respect of the holder's conversion privilege. The Corporation
hereby waives to the fullest extent permitted any rights to relief it may have
under 11 U.S.C. Section 362 in respect of the conversion of the Series F
Convertible Preferred Stock. The Corporation agrees, without cost or expense to
the holder, to take or consent to any and all action necessary to effectuate
relief under 11 U.S.C. Section 362.

               (e)    FRACTIONAL SHARES. No fractional shares shall be issued
upon conversion of Series F Convertible Preferred Stock into Common Stock. All
fractional shares shall be rounded up to the nearest whole share.

               (f)    REORGANIZATION OR RECLASSIFICATION. If any capital
reorganization or reclassification of the capital stock of the Corporation shall
be effected in such a way that holders of Common Stock shall be entitled to
receive stock, securities or assets with respect to or in exchange for Common
Stock, or, in the case of any consolidation, merger or mandatory share exchange
of the Corporation into any other company, then, as a condition of such
reorganization, reclassification or exchange, lawful and adequate provisions
shall be made whereby each holder of a share or shares of Series F Convertible
Preferred Stock shall thereupon have the right to receive, upon the basis and
upon the terms and conditions specified herein and in lieu of the shares of
Common Stock immediately theretofore receivable upon the conversion of such
share or shares of Series F Convertible Preferred Stock, such shares of stock,
securities or assets as may be issued or payable with respect to or in exchange
for a number of outstanding shares of such Common Stock equal to the number of
shares of such Common Stock immediately theretofore receivable upon such
conversion had such reorganization, reclassification or exchange not taken
place, and in any such case appropriate provisions shall be made with respect to
the rights and interests of such holder to the end that the provisions hereof
(including without limitation provisions for adjustments of the conversion
rights) shall thereafter be applicable, as nearly as may be, in relation to any
shares of stock, securities or assets thereafter deliverable upon the exercise
of such conversion rights.

               (g)    ADJUSTMENTS FOR SPLITS, COMBINATIONS, ETC. The Conversion
Price and the number of shares of Common Stock into which the Series F
Convertible Preferred Stock shall be convertible shall be adjusted for stock
splits, combinations, or other similar events. Additionally, an adjustment will
be made in the case of an exchange of Common Stock, consolidation or merger of
the Corporation with or into another corporation or sale of all or substantially
all of the assets of the Corporation in order to enable the holder of Series F
Convertible Preferred Stock to acquire the kind and the number of shares of
stock or other securities or property receivable in such event by a holder of
the number of shares of Common Stock that might otherwise have been issued upon
the conversion of the Series F Convertible Preferred Stock. No adjustment to the
Conversion Price will be made for dividends (other than stock dividends), if
any, paid on the Common Stock or for securities issued pursuant to exercise for
fair value of options, warrants, or restricted stock.

               (h)    ADJUSTMENTS TO CONVERSION RATIO. For so long as any shares
of Series F Convertible Preferred Stock are outstanding, but no later than one
year from the effective date of a registration statement registering for resale
by the holders the shares of Common Stock issuable

<PAGE>   38

                                                                               9

upon conversion of the Series F Convertible Preferred Stock, if the Corporation
(i) issues and sells pursuant to an exemption from registration under the
Securities Act (A) Common Stock at a purchase price on the date of issuance
thereof that is lower than the Conversion Price at such date (other than shares
of Common Stock issued upon conversion of the Corporation's convertible
preferred stock outstanding on the Original Issuance Date, or in connection with
the exercise of any warrants or options outstanding on the Original Issuance
Date or pursuant to the Corporation's 1998 Employee Stock Purchase Plan), (B)
warrants or options with an exercise price on the date of issuance of the
warrants or options that is lower than the Conversion Price on such date (other
than options and stock awards granted pursuant to the Corporation's 1995 and
1998 Stock Option Plans), or (C) convertible, exchangeable or exercisable
securities with a right to convert, exchange or exercise at a price or rate
lower than the Conversion Price on the date of issuance or conversion, as
applicable, of such convertible, exchangeable or exercisable securities (other
than the options and stock awards granted pursuant to the Corporation's 1995 and
1998 Stock Option Plans); and (ii) grants the right to the purchaser(s) thereof
to demand that the Corporation register under the Securities Act such Common
Stock issued or the Common Stock for which such warrants or options may be
exercised or such convertible, exchangeable or exercisable securities may be
converted, exercised or exchanged, then the Conversion Price shall be reduced to
a rate equal to the lowest of any lower rates since the most recently received
Conversion Notice, and such Adjusted Conversion Price shall apply to any future
Conversion Notices received by the Corporation, unless the unadjusted Conversion
Price would be lower than the Adjusted Conversion Price. The Adjusted Conversion
Price as it may exist from time to time shall not apply retroactively to any
shares of Series F Convertible Preferred Stock converted prior to the
implementation of such Adjusted Conversion Price. Notwithstanding the foregoing,
the Corporation may issue up to an aggregate total of Three Hundred Thousand
(300,000) shares of Common Stock (subject to adjustment only for stock splits,
stock dividends and reverse stock splits) at any price determined by the Board
of Directors, after the Original Issuance Date, without causing an Adjusted
Conversion Price.

         6.    MANDATORY CONVERSION.

               (a)    MANDATORY CONVERSION DATE. If on or after the third
anniversary of the Original Issuance Date (such date as selected by the
Corporation being the "Mandatory Conversion Date"), there remain issued and
outstanding any shares of Series F Convertible Preferred Stock, then the
Corporation shall be entitled to require all (but not less than all) holders of
shares of Series F Convertible Preferred Stock then outstanding to convert their
shares of Series F Convertible Preferred Stock into shares of Common Stock or,
at the option of the Corporation, to buy out all such holders in cash, at the
price set forth in Paragraph 5(a). The Corporation shall provide written notice
(the "Mandatory Conversion Notice") to the holders of shares of Series F
Convertible Preferred Stock of such mandatory conversion or such mandatory
buy-out. The Mandatory Conversion Notice shall include (i) the Stated Value of
the shares of Series F Convertible Preferred Stock to be converted or bought
out, (ii) the Conversion Price at the Mandatory Conversion Date, and (iii) the
number of shares of the Corporation's Common Stock to be issued (or the amount
of cash to be paid in the event of a buy-out) upon such mandatory conversion or
such mandatory buy-out at the then applicable Conversion Price. Notwithstanding
the foregoing, in no event shall the Corporation convert that portion of the
Series F Convertible Preferred Stock to the extent that the issuance of Common
Stock upon the conversion of such Series F Convertible Preferred Stock, when
combined with shares of Common Stock received upon other conversions of Series F
Convertible

<PAGE>   39
                                                                              10

Preferred Stock and exercise of the warrants issued in connection with the
purchase of Series F Convertible Preferred Stock by such holder and any other
holders of Series F Convertible Preferred Stock, would exceed 19.99% of the
number of shares of Common Stock outstanding on the Original Issuance Date, or
as to any individual holder, make such holder the beneficial owner of more than
5% of the Corporation's then outstanding Common Stock.

               (b)    SURRENDER OF CERTIFICATES. On or before the Mandatory
Conversion Date, each holder of shares of Series F Convertible Preferred Stock
shall surrender his or its certificate or certificates for all such shares to
the Corporation at the place designated in such Mandatory Conversion Notice (or
an affidavit of lost certificate in form and content reasonably satisfactory to
the Corporation), and shall thereafter receive certificates for the number of
shares of Common Stock to which such holder is entitled or, in the event of a
buy-out by the Corporation, the amount of cash to which such holder is entitled
within three business days. On the Mandatory Conversion Date, all rights with
respect to the Series F Convertible Preferred Stock so converted will terminate.
All certificates evidencing shares of Series F Convertible Preferred Stock that
are required to be surrendered for conversion in accordance with the provisions
hereof, from and after the Mandatory Conversion Date, shall be deemed to have
been retired and cancelled, notwithstanding the failure of the holder or holders
thereof to surrender such certificates on or prior to such date. The Corporation
may thereafter take such appropriate action as may be necessary to reduce the
authorized Series F Convertible Preferred Stock accordingly.

         7.    REDEMPTION OF SERIES F CONVERTIBLE PREFERRED  STOCK.

               (a)    RIGHT TO REDEEM SERIES F CONVERTIBLE PREFERRED STOCK. At
any time, and from time to time, on and after the expiration of the earlier of
(i) six months from the Original Issuance Date, or (ii) the closing of a
registered firm-commitment underwritten secondary offering of equity securities
by the Corporation for cash, the Corporation may, in its sole discretion, but
shall not be obligated to, redeem, in whole or in part, the then issued and
outstanding shares of Series F Convertible Preferred Stock, at a price (the
"Redemption Price") equal to the greater of (x) $1,500 per share of such Series
F Convertible Preferred Stock and (y) an amount equal to the product of the
closing sale price of a share of Common Stock on the Principal Market on the
Trading Day prior to the date of the Redemption Notice (as hereinafter defined)
and the number of shares of Common Stock into which such shares of Series F
Convertible Preferred Stock could be converted on the date of the Redemption
Notice.

               (b)    NOTICE OF REDEMPTION. The Corporation shall provide each
holder of record of the Series F Convertible Preferred Stock being redeemed with
written notice of redemption (the "Redemption Notice") not less than 30 days
prior to any date stipulated by the Corporation for the redemption of the Series
F Convertible Preferred Stock (the "Redemption Date"). The Redemption Notice
shall contain (i) the Redemption Date, (ii) the number of shares of Series F
Convertible Preferred Stock to be redeemed from the holder to whom the
Redemption Notice is delivered, (iii) instructions for surrender to the
Corporation of the certificate or certificates representing the shares of Series
F Convertible Preferred Stock to be redeemed, and (iv) a procedure for the
holder to specify the number of shares of Series F Convertible Preferred Stock
to be converted into Common Stock pursuant to Paragraph 5.

<PAGE>   40
                                                                              11

               (c)    RIGHT TO CONVERT SERIES F CONVERTIBLE PREFERRED STOCK UPON
RECEIPT OF REDEMPTION NOTICE. Upon receipt of the Redemption Notice, the
recipient thereof shall have the option, at its sole election, to specify what
portion of the Series F Convertible Preferred Stock called for redemption in the
Redemption Notice shall be redeemed as provided in this Paragraph 7 or converted
into Common Stock in the manner provided in Paragraph 5. If the holder of the
Series F Convertible Preferred Stock called for redemption elects to convert any
of such shares, then such conversion shall take place on the Conversion Date
specified by the holder, but in no event after the Redemption Date, in
accordance with the terms of Paragraph 5.

               (d)    SURRENDER OF CERTIFICATES; PAYMENT OF REDEMPTION PRICE. On
or before the Redemption Date, each holder of the shares of Series F Convertible
Preferred Stock to be redeemed shall surrender the required certificate or
certificates representing such shares to the Corporation, in the manner and at
the place designated in the Redemption Notice, and upon payment to the holder of
the Redemption Price, each such surrendered certificate shall be cancelled and
retired. If payment of such redemption price is not made in full by the
Redemption Date, the holder shall again have the right to convert the Series F
Convertible Preferred Stock as provided in Paragraph 5 hereof and the
Corporation's right of redemption under this Paragraph 7 shall cease to exist
from and after the Redemption Date. If a certificate is surrendered and all the
shares evidenced thereby are not being redeemed, the Corporation shall issue new
certificates to be registered in the names of the person(s) whose name(s)
appear(s) as the owners on the respective surrendered certificates and deliver
such certificate to such person(s).

         8.    NOTICES. In case at any time:

               (a)    the Corporation shall declare any dividend upon its Common
Stock payable in cash or stock or make any other pro rata distribution to the
holders of its Common Stock; or

               (b)    the Corporation shall offer for subscription pro rata to
the holders of its Common Stock any additional shares of stock of any class or
other rights; or

               (c)    there shall be any capital reorganization or
reclassification of the capital stock of the Corporation, or a consolidation or
merger of the Corporation with or into, or a sale of all or substantially all
its assets to, another entity or entities; or

               (d)    there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Corporation;

               then, in any one or more of said cases, the Corporation shall
give, by first class mail, postage prepaid, or by telex or facsimile or by
recognized overnight delivery service to non-U.S. residents, addressed to each
holder of any shares of Series F Convertible Preferred Stock at the address of
such holder as shown on the books of the Corporation, (i) at least 10 days'
prior written notice of the date on which the books of the Corporation shall
close or a record shall be taken for such dividend, distribution or subscription
rights or for determining rights to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding

                                                                              12

up and (ii) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding up, at least 10
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause (i) shall also specify, in the
case of any such dividend, distribution or subscription rights, the date on
which the holders of Common Stock shall be entitled thereto and (ii) shall also
specify the date on which the holders of Common Stock shall be entitled to
exchange their Common Stock for securities or other property deliverable upon
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding up, as the case may be.

         9.    STOCK TO BE RESERVED. The Corporation, upon the effective date of
this Certificate of Designations, has a sufficient number of shares of Common
Stock available to reserve for issuance upon the conversion of all outstanding
shares of Series F Convertible Preferred Stock. The Corporation will at all
times reserve and keep available out of its authorized Common Stock, solely for
the purpose of issuance upon the conversion of Series F Convertible Preferred
Stock as herein provided, such number of shares of Common Stock as shall then be
issuable upon the conversion of all outstanding shares of Series F Convertible
Preferred . The Corporation covenants that all shares of Common Stock which
shall be so issued shall be duly and validly issued, fully paid and
non-assessable. The Corporation will take all such action as may be so taken
without violation of any applicable law or regulation, or of any requirement of
any national securities exchange upon which the Common Stock may be listed to
have a sufficient number of authorized but unissued shares of Common Stock to
issue upon conversion of the Series F Convertible Preferred Stock. The
Corporation will not take any action which results in any adjustment of the
conversion rights if the total number of shares of Common Stock issued and
issuable after such action upon conversion of the Series F Convertible Preferred
Stock would exceed the total number of shares of Common Stock then authorized by
the Corporation's Restated Certificate of Incorporation, as amended.

         10.   NO REISSUANCE OF SERIES F CONVERTIBLE PREFERRED STOCK. Shares of
Series F Convertible Preferred Stock which are converted into shares of Common
Stock as provided herein shall not be reissued.

         11.   ISSUE TAX. The issuance of certificates for shares of Common
Stock upon conversion of Series F Convertible Preferred Stock shall be made
without charge to the holder for any United States issuance tax in respect
thereof, provided that the Corporation shall not be required to pay any tax
which may be payable in respect of any transfer involved in the issuance and
delivery of any certificate in a name other than that of the holder of the
Series F Convertible Preferred Stock which is being converted.

         12.   CLOSING OF BOOKS. The Corporation will at no time close its
transfer books against the transfer of any Series F Convertible Preferred Stock
or of any shares of Common Stock issued or issuable upon the conversion of any
shares of Series F Convertible Preferred Stock in any

<PAGE>   42
                                                                              13

manner which interferes with the timely conversion of such Series F Convertible
Preferred Stock, except as may otherwise be required to comply with applicable
securities laws.

         13.   DEFINITIONS. As used in this Certificate of Designations, the
term "Common Stock" shall mean and include the Corporation's authorized Common
Stock, $0.01 par value, as constituted on the date of filing of this Certificate
of Designations authorizing the issuance of the Series F Convertible Preferred
Stock, and shall also include any capital stock of any class of the Corporation
thereafter authorized which shall neither be limited to a fixed sum or
percentage of par value in respect of the rights of the holders thereof to
participate in dividends nor entitled to a preference in the distribution of
assets upon the voluntary or involuntary liquidation, dissolution or winding up
of the Corporation; provided that the shares of Common Stock receivable upon
conversion of shares of Series F Convertible Preferred Stock shall include only
shares designated as Common Stock of the Corporation on the date of filing of
this instrument, or in case of any reorganization, reclassification, or stock
split of the outstanding shares thereof, the stock, securities or assets
provided for in Subparagraph 5(f) and (g). Any capitalized terms used in this
Certificate of Designations but not defined herein shall have the meanings set
forth in that certain Preferred Stock Purchase Agreement among the Corporation
and the other persons signatory thereto relating to the issuance and sale of the
Series F Convertible Preferred Stock to the holders of the Series F Convertible
Preferred Stock on the Original Issuance Date, a copy of which will be provided
to any stockholder of the Corporation upon request to the Secretary of the
Corporation, without charge.

         14.   LOSS, THEFT, DESTRUCTION OF PREFERRED STOCK. Upon receipt of
evidence satisfactory to the Corporation of the loss, theft, destruction or
mutilation of certificates representing shares of Series F Convertible Preferred
Stock and, in the case of any such loss, theft or destruction, upon receipt of
indemnity reasonably satisfactory to the Corporation (which shall not include
the posting of any bond), or, in the case of any such mutilation, upon surrender
and cancellation of the Series F Convertible Preferred Stock certificate, the
Corporation shall make, issue and deliver, in lieu of such lost, stolen,
destroyed or mutilated certificates for Series F Convertible Preferred Stock,
new certificates for Series F Convertible Preferred Stock of like tenor.

         15.   WHO DEEMED ABSOLUTE OWNER. The Corporation may deem the person in
whose name the Series F Convertible Preferred Stock shall be registered upon the
registry books of the Corporation to be, and may treat it as, the absolute owner
of the Series F Convertible Preferred Stock for the purpose of conversion of the
Series F Convertible Preferred Stock and for all other purposes, and the
Corporation shall not be affected by any notice to the contrary. All such
payments and such conversion shall be valid and effectual to satisfy and
discharge the liability upon the Series F Convertible Preferred Stock to the
extent of the sum or sums so paid or the conversion so made.

         16.   REGISTER. The Corporation shall keep at its principal office a
register in which the Corporation shall provide for the registration of the
Series F Convertible Preferred Stock. Upon any transfer of the Series F
Convertible Preferred Stock in accordance with the provisions hereof, the
Corporation shall register such transfer on the Series F Convertible Preferred
Stock register.

         17.   WITHHOLDING. To the extent required by applicable law, the
Corporation may withhold amounts for or on account of any taxes imposed or
levied by or on behalf of any taxing authority in the United States having
jurisdiction over the Corporation from any payments made pursuant to the Series
F Convertible Preferred Stock.

                        INTEGRATED SURGICAL SYSTEMS, INC.

THIS CERTIFIES that, for value received, _________________________ (the

is being issued in connection with the Agreement and is subject to its terms and
conditions. In the event of any conflict between the terms of this Warrant and

<PAGE>   45

         1.    Title of Warrant. Prior to the expiration hereof and subject to
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by the
holder hereof in person or by duly authorized attorney, upon surrender of this
Warrant together with the Assignment Form annexed hereto properly endorsed.

         2.    Authorization of Shares. The Company covenants that all shares of
Common Stock which may be issued upon the exercise of rights represented by this
Warrant will, upon exercise of the rights represented by this Warrant, be duly
authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges in respect of the issue thereof (other than taxes in
respect of any transfer occurring contemporaneously with such issue).

         3.    Exercise of Warrant. (a) Except as provided in Section 4 herein,
exercise of the purchase rights represented by this Warrant may be made at any
time or times, before the close of business on the Termination Date, or such
earlier date on which this Warrant may terminate as provided in this Warrant, by
the surrender of this Warrant and the Notice of Exercise Form annexed hereto
duly executed, at the office of the Company (or such other office or agency of
the Company as it may designate by notice in writing to the registered holder
hereof at the address of such holder appearing on the books of the Company) and
upon payment of the Exercise Price of the shares thereby purchased by cash,
check or bank draft payable to the Company or by wire transfer or cashier's
check drawn on a United States bank; whereupon the holder of this Warrant shall
be entitled to receive a certificate for the number of shares of Common Stock so
purchased. Certificates for shares purchased hereunder shall be delivered to the
holder hereof within three (3) business days after the date on which this
Warrant shall have been exercised as aforesaid. Payment of the Exercise Price of
the shares may be by certified check or cashier's check or by wire transfer to
an account designated by the Company in an amount equal to the Exercise Price
multiplied by the number of Warrant Shares. This Warrant shall be deemed to have
been exercised and such certificate or certificates shall be deemed to have been
issued, and Holder or any other person so designated to be named therein shall
be deemed to have become a holder of record of such shares for all purposes, as
of the date the Warrant has been exercised by payment to the Company of the
Warrant purchase price and all taxes required to be paid by Holder, if any,
pursuant to Section 5 prior to the issuance of such shares have been paid. If
this Warrant shall have been exercised in part, the Company shall, at the time
of delivery of the certificate or certificates representing Warrant Shares,
deliver to Holder a new Warrant evidencing the rights of Holder to purchase the
unpurchased shares of Common Stock called for by this Warrant, which new Warrant
shall in all other respects be identical with this Warrant.

               (b)    Notwithstanding anything to the contrary contained herein,
if the issuance of the number of shares of Common Stock upon the exercise of
this Warrant, when added to the number of shares of Common Stock previously
issued by the Company upon conversion of shares of the Company's Series F
Convertible Preferred Stock and upon exercise of this Warrant and the other
warrants issued in connection with the sale of shares of Series F Convertible
Preferred Stock, would result in the issuance of more than 19.9% of the number
of shares of Common Stock which were issued and outstanding on the date upon
which the Series F Convertible Preferred Stock was

                                       2
<PAGE>   46

originally issued (the "Nasdaq Limit"), then the Holder may exercise this
Warrant only as to a number of shares of Common Stock that is not in excess of
the Nasdaq Limit, unless prior to such exercise, the Company shall have obtained
the approval of its voting stockholders to such issuance, if required in
accordance with the rules of the Nasdaq Stock Market, Inc. or any securities
exchange upon which the Common Stock is listed. To the extent the number of
shares of Common Stock issuable upon exercise of this Warrant would but for the
limitation set forth in this paragraph exceed the Nasdaq Limit, the Company
shall pay the Holder an amount in cash equal to the product of the closing sale
price of a share of Common Stock on the Trading Date immediately preceding of
the date of the Notice of Exercise and the number of shares of Common Stock in
excess of the Nasdaq Limit set forth in the Notice of Exercise that would have
been issued to the Holder upon such exercise but for such limitation.

               (c)    The Holder shall be entitled to exercise the Warrant
notwithstanding the commencement of any case under 11 U.S.C. Section 101 et seq.
(the "Bankruptcy Code"). In the event the Company is a debtor under the
Bankruptcy Code, the Company hereby waives to the fullest extent permitted any
rights to relief it may have under 11 U.S.C. Section 362 in respect of the
Holder's exercise right. The Company hereby waives to the fullest extent
permitted any rights to relief it may have under 11 U.S.C. Section 362 in
respect of the exercise of the Warrant. The Company agrees, without cost or
expense to the Holder, to take or consent to any and all action necessary to
effectuate relief under 11 U.S.C. Section 362.

               (d)    If a registration statement for the resale of the Warrant
Shares that may be acquired upon exercise of this Warrant is not in effect at
any time from and after one year from the issuance date of this Warrant, then
the Holder shall have the right to a "cashless exercise" in which the Holder4
shall be entitled to receive a certificate for the number of shares equal to the
quotient obtained by dividing [(A-B) (X)] by (A), where:

         (A) = the closing bid price per share of Common Stock on the Trading
Day preceding the date of such election;

         (B) = the Exercise Price of this Warrant; and

         (X) = the number of shares that may be acquired upon exercise of this
Warrant in accordance with the terms of this Warrant.

         4.    No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to the same fraction of the
Market Price per share of Common Stock as of the Closing Date.

         5.    Charges, Taxes and Expenses. Issuance of certificates for shares
of Common Stock upon the exercise of this Warrant shall be made without charge
to the holder hereof for any issue or

                                       3
<PAGE>   47

transfer tax or other incidental expense in respect of the issuance of such
certificate, all of which taxes and expenses shall be paid by the Company, and
such certificates shall be issued in the name of the holder of this Warrant or
in such name or names as may be directed by the holder of this Warrant;
provided, however, that in the event certificates for shares of Common Stock are
to be issued in a name other than the name of the holder of this Warrant, this
Warrant when surrendered for exercise shall be accompanied by the Assignment
Form attached hereto duly executed by the holder hereof; and provided further,
that upon any transfer involved in the issuance or delivery of any certificates
for shares of Common Stock, the Company may require, as a condition thereto, the
payment of a sum sufficient to reimburse it for any transfer tax incidental
thereto.

         6.    Closing of Books. The Company will not close its shareholder
books or records in any manner which prevents the timely exercise of this
Warrant.

         7.    Transfer, Division and Combination. (a) Subject to compliance
with any applicable securities laws, transfer of this Warrant and all rights
hereunder, in whole or in part, shall be registered on the books of the Company
to be maintained for such purpose, upon surrender of this Warrant at the
principal office of the Company, together with a written assignment of this
Warrant substantially in the form attached hereto duly executed by Holder or its
agent or attorney and funds sufficient to pay any transfer taxes payable upon
the making of such transfer. Upon such surrender and, if required, such payment,
the Company shall execute and deliver a new Warrant or Warrants in the name of
the assignee or assignees and in the denomination specified in such instrument
of assignment, and shall issue to the assignor a new Warrant evidencing the
portion of this Warrant not so assigned, and this Warrant shall promptly be
cancelled. A Warrant, if properly assigned, may be exercised by a new Holder for
the purchase of shares of Common Stock without having a new Warrant issued.

               (b)    This Warrant may be divided or combined with other
Warrants upon presentation hereof at the aforesaid office of the Company,
together with a written notice specifying the names and denominations in which
new Warrants are to be issued, signed by Holder or its agent or attorney.
Subject to compliance with Section 7(a), as to any transfer which may be
involved in such division or combination, the Company shall execute and deliver
a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided
or combined in accordance with such notice.

               (c)    The Company shall prepare, issue and deliver at its own
expense (other than transfer taxes) the new Warrant or Warrants under this
Section 7.

               (d)    The Company agrees to maintain, at its aforesaid office,
books for the registration and the registration of transfer of the Warrants.

         8.    No Rights as Shareholder until Exercise. This Warrant does not
entitle the holder hereof to any voting rights or other rights as a shareholder
of the Company prior to the exercise thereof. Upon the surrender of this Warrant
and the payment of the aggregate Exercise Price, the

                                       4
<PAGE>   48

Warrant Shares so purchased shall be and be deemed to be issued to such holder
as the record owner of such shares as of the close of business on the later of
the date of such surrender or payment.

         9.    Loss, Theft, Destruction or Mutilation of Warrant. The Company
represents and warrants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant
certificate or any stock certificate relating to the Warrant Shares, and in case
of loss, theft or destruction, of indemnity or security reasonably satisfactory
to it, and upon surrender and cancellation of such Warrant or stock certificate,
if mutilated, the Company will make and deliver a new Warrant or stock
certificate of like tenor and dated as of such cancellation, in lieu of such
Warrant or stock certificate.

         10.   Saturdays, Sundays, Holidays, etc. If the last or appointed day
for the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday, then such action may be
taken or such right may be exercised on the next succeeding day not a Saturday,
Sunday or legal holiday.

         11.   (a)    Adjustments of Exercise Price and Number of Warrant
Shares. The number and kind of securities purchasable upon the exercise of this
Warrant and the Exercise Price shall be subject to adjustment from time to time
upon the happening of any of the following. In case the Company shall (i)
declare or pay a dividend in shares of Common Stock or make a distribution in
shares of Common Stock to holders of its outstanding Common Stock, (ii)
subdivide its outstanding shares of Common Stock, (iii) combine its outstanding
shares of Common Stock into a smaller number of shares of Common Stock or (iv)
issue any shares of its capital stock in a reclassification of the Common Stock,
then the number of Warrant Shares purchasable upon exercise of this Warrant
immediately prior thereto shall be adjusted so that the holder of this Warrant
shall be entitled to receive the kind and number of Warrant Shares or other
securities of the Company which he would have owned or have been entitled to
receive had such Warrant been exercised in advance thereof. Upon each such
adjustment of the kind and number of Warrant Shares or other securities of the
Company which are purchasable hereunder, the holder of this Warrant shall
thereafter be entitled to purchase the number of Warrant Shares or other
securities resulting from such adjustment at an Exercise Price per such Warrant
Share or other security 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 by the number
of Warrant Shares or other securities of the Company resulting from such
adjustment. An adjustment made pursuant to this paragraph shall become effective
immediately after the effective date of such event retroactive to the record
date, if any, for such event.

               (b)    Reorganization, Reclassification, Merger, Consolidation or
Disposition of Assets. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to the Common Stock of the Company),
or sell, transfer or otherwise dispose of all or substantially all its property,
assets or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation

                                       5
<PAGE>   49

or disposition of assets, shares of common stock of the successor or acquiring
corporation, or any cash, shares of stock or other securities or property of any
nature whatsoever (including warrants or other subscription or purchase rights)
in addition to or in lieu of common stock of the successor or acquiring
corporation ("Other Property"), are to be received by or distributed to the
holders of Common Stock of the Company, then Holder shall have the right
thereafter to receive, upon exercise of the Warrant, the number of shares of
common stock of the successor or acquiring corporation or of the Company, if it
is the surviving corporation, and Other Property receivable upon or as a result
of such reorganization, reclassification, merger, consolidation or disposition
of assets by a holder of the number of shares of Common Stock for which this
Warrant is exercisable immediately prior to such event. In case of any such
reorganization, reclassification, merger, consolidation or disposition of
assets, the successor or acquiring corporation (if other than the Company) shall
expressly assume the due and punctual observance and performance of each and
every covenant and condition of this Warrant to be performed and observed by the
Company and all the obligations and liabilities hereunder, subject to such
modifications as may be deemed appropriate (as determined by resolution of the
Board of Directors of the Company) in order to provide for adjustments of shares
of Common Stock for which this Warrant is exercisable which shall be as nearly
equivalent as practicable to the adjustments provided for in this Section 11.
For purposes of this Section 11, "common stock of the successor or acquiring
corporation" shall include stock of such corporation of any class which is not
preferred as to dividends or assets over any other class of stock of such
corporation and which is not subject to redemption and shall also include any
evidences of indebtedness, shares of stock or other securities which are
convertible into or exchangeable for any such stock, either immediately or upon
the arrival of a specified date or the happening of a specified event and any
warrants or other rights to subscribe for or purchase any such stock. The
foregoing provisions of this Section 11 shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or disposition of
assets.

               (c)    Certain Limitations. Notwithstanding anything herein to
the contrary, the Company agrees not to enter into any transaction which, by
reason of any adjustment hereunder, would cause the Exercise Price to be less
than the par value per share of Common Stock.

         12.   Voluntary Adjustment by the Company. The Company may at any time
during the term of this Warrant, reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

         13.   Notice of Adjustment. Whenever the number of Warrant Shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall promptly mail by registered or certified mail, return receipt requested,
to the holder of this Warrant notice of such adjustment or adjustments setting
forth the number of Warrant Shares (and other securities or property)
purchasable upon the exercise of this Warrant and the Exercise Price of such
Warrant Shares (and other securities or property) after such adjustment, setting
forth a brief statement of the facts requiring such adjustment and setting forth
the computation by which such adjustment was made. Such notice, in absence of
manifest error, shall be conclusive evidence of the correctness of such
adjustment.

                                       6

<PAGE>   50

         14.   Notice of Corporate Action.  If at any time

               (a)    the Company shall take a record of the holders of its
Common Stock for the purpose of entitling them to receive a dividend or other
distribution, or any right to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or
property, or to receive any other right, or

               (b)    there shall be any capital reorganization of the Company,
any reclassification or recapitalization of the capital stock of the Company or
any consolidation or merger of the Company with, or any sale, transfer or other
disposition of all or substantially all the property, assets or business of the
Company to, another corporation or,

               (c)    there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 30 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 30
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause also shall specify (i) the date
on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their shares of Common Stock for securities or other
property deliverable upon such disposition, dissolution, liquidation or winding
up. Each such written notice shall be sufficiently given if addressed to Holder
at the last address of Holder appearing on the books of the Company and
delivered in accordance with Section 17(d).

         15.   Authorized Shares. The Company covenants that during the period
the Warrant is outstanding, it will reserve from its authorized and unissued
Common Stock a sufficient number of shares to provide for the issuance of the
Warrant Shares upon the exercise of any purchase rights under this Warrant. The
Company further covenants that its issuance of this Warrant shall constitute
full authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of NASDAQ or any domestic
securities exchange upon which the Common Stock may be listed.

                                       7
<PAGE>   51

               The Company shall not by any action, including, without
limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, 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 of this Warrant, 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 to protect the
rights of Holder against impairment. Without limiting the generality of the
foregoing, the Company will (a) not increase the par value of any shares of
Common Stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise immediately prior to such increase in par
value, (b) take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant, and (c) use its best efforts to
obtain all such authorizations, exemptions or consents from any public
regulatory body having jurisdiction thereof as may be necessary to enable the
Company to perform its obligations under this Warrant.

               Upon the request of Holder, the Company will at any time during
the period this Warrant is outstanding acknowledge in writing, in form
reasonably satisfactory to Holder, the continuing validity of this Warrant and
the obligations of the Company hereunder.

               Before taking any action which would cause an adjustment reducing
the current Exercise Price below the then par value, if any, of the shares of
Common Stock issuable upon exercise of the Warrants, the Company shall take any
corporate action which may be necessary in order that the Company may validly
and legally issue fully paid and non-assessable shares of such Common Stock at
such adjusted Exercise Price.

               Before taking any action which would result in an adjustment in
the number of shares of Common Stock for which this Warrant is exercisable or in
the Exercise Price, the Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

         16.   Required Registration. Pursuant to the terms and conditions set
forth in the Registration Rights Agreement entered into between the Company and
the Holders as of the date of issuance of this Warrant, the Company shall
prepare and file with the Commission not later than the 45th day after the
Closing Date, a Registration Statement relating to the offer and sale of the
Common Stock issuable upon exercise of the Warrants and shall use its best
efforts to cause the Commission to declare such Registration Statement effective
under the Securities Act as promptly as practicable but no later than 90 days
after the closing date.

         17.   Miscellaneous.

               (a)    Issue Date; Jurisdiction. The provisions of this Warrant
shall be construed and shall be given effect in all respects as if it had been
issued and delivered by the Company on the date hereof. This Warrant shall be
binding upon any successors or assigns of the Company. This

                                       8
<PAGE>   52

Warrant shall constitute a contract under the laws of New York without regard to
its conflict of law, principles or rules, and be subject to arbitration pursuant
to the terms set forth in the Agreement.

               (b)    Restrictions. The holder hereof acknowledges that the
Warrant Shares acquired upon the exercise of this Warrant, if not registered,
will have restrictions upon resale imposed by state and federal securities laws.

               (c)    Nonwaiver and Expenses. No course of dealing or any delay
or failure to exercise any right hereunder on the part of Holder shall operate
as a waiver of such right or otherwise prejudice Holder's rights, powers or
remedies, notwithstanding all rights hereunder terminate on the Termination
Date. If the Company fails to make, when due, any payments provided for
hereunder, or fails to comply with any other provision of this Warrant, the
Company shall pay to Holder such amounts as shall be sufficient to cover any
costs and expenses including, but not limited to, reasonable attorneys' fees,
including those of appellate proceedings, incurred by Holder in collecting any
amounts due pursuant hereto or in otherwise enforcing any of its rights, powers
or remedies hereunder.

               (d)    Notices. Any notice, request or other document required or
permitted to be given or delivered to the holder hereof by the Company shall be
delivered in accordance with the notice provisions of the Agreement.

               (e)    Limitation of Liability. No provision hereof, in the
absence of affirmative action by Holder to purchase shares of Common Stock, and
no enumeration herein of the rights or privileges of Holder hereof, shall give
rise to any liability of Holder for the purchase price of any Common Stock or as
a stockholder of the Company, whether such liability is asserted by the Company
or by creditors of the Company.

               (f)    Remedies. Holder, in addition to being entitled to
exercise all rights granted by law, including recovery of damages, will be
entitled to specific performance of its rights under this Warrant. The Company
agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of the provisions of this Warrant and
hereby agrees to waive the defense in any action for specific performance that a
remedy at law would be adequate.

               (g)    Successors and Assigns. Subject to applicable securities
laws, this Warrant and the rights evidenced hereby shall inure to the benefit of
and be binding upon the successors of the Company and the successors and assigns
of Holder. The provisions of this Warrant are intended to be for the benefit of
all Holders from time to time of this Warrant and shall be enforceable by any
such Holder or holder of Warrant Stock.

               (h)    Cooperation. The Company shall cooperate with Holder in
supplying such information as may be reasonably necessary for Holder to complete
and file any information reporting forms presently or hereafter required by the
Commission as a condition to the availability of an exemption from the
Securities Act for the sale of any Warrant or Restricted Common Stock.

                                       9
<PAGE>   53

               (i)    Indemnification. The Company agrees to indemnify and hold
harmless Holder from and against any liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, claims, costs, attorneys' fees, expenses
and disbursements of any kind which may be imposed upon, incurred by or asserted
against Holder in any manner relating to or arising out of any failure by the
Company to perform or observe in any material respect any of its covenants,
agreements, undertakings or obligations set forth in this Warrant; provided,
however, that the Company will not be liable hereunder to the extent that any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
claims, costs, attorneys' fees, expenses or disbursements are found in a final
non-appealable judgment by a court to have resulted from Holder's negligence,
bad faith or willful misconduct in its capacity as a stockholder or
warrantholder of the Company.

               (j)    Amendment. This Warrant and all other Warrants may be
modified or amended or the provisions hereof waived with the written consent of
the Company and the Holder.

               (k)    Severability. Wherever possible, each provision of this
Warrant shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provisions or the remaining provisions of this Warrant.

               (l)    Headings. The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

         IN WITNESS WHEREOF, the Company has caused this Warrant to be executed
by its officer thereunto duly authorized.

                          REGISTRATION RIGHTS AGREEMENT

THIS REGISTRATION RIGHTS AGREEMENT, dated as of the 8th day of February, 2000,
between INTEGRATED SURGICAL SYSTEMS, INC., a corporation incorporated under the
laws of the State of Delaware, and having its principal place of business at
1850 Research Park Drive, Davis, California 95616-4884 (the "Company") and the
person signatory hereto (the "Holder").

         WHEREAS, simultaneously with the execution and delivery of this
Agreement, the Holder is purchasing from the Company, pursuant to a Preferred
Stock Purchase Agreement dated the date hereof (the "Purchase Agreement"),
__________ shares of Series F Convertible Preferred Stock, $0.01 par value and a
Warrant to purchase ___________ shares of the Company's Common Stock (terms not
defined herein shall have the meanings ascribed to them in the Purchase
Agreement); and

         WHEREAS, the Company desires to grant to the Holder the registration
rights set forth herein with respect to the shares of Common Stock issuable upon
conversion of the Series E Convertible Preferred Stock and shares of Common
Stock underlying the Warrant (hereinafter referred to as the "Stock" or
"Securities" of the Company).

         NOW, THEREFORE, the parties hereto mutually agree as follows:

         Section 1. Registrable Securities. As used herein the term "Registrable
Security" means the Securities; provided, however, that with respect to any
particular Registrable Security, such security shall cease to be a Registrable
Security when, as of the date of determination, (i) it has been effectively
registered under the Securities Act of 1933, as amended (the "1933 Act") and
disposed of pursuant thereto, (ii) registration under the 1933 Act is no longer
required for the immediate public distribution of such security without
limitation as to volume as a result of the provisions of Rule 144 promulgated
under the 1933 Act, or (iii) it has ceased to be outstanding. The term
"Registrable Securities" means any and/or all of the securities falling within
the foregoing definition of a "Registrable Security." In the event of any
merger, reorganization, consolidation, recapitalization or other change in
corporate structure affecting the Common Stock, such adjustment shall be deemed
to be made in the definition of "Registrable Security" as is appropriate in
order to prevent any dilution or enlargement of the rights granted pursuant to
this Agreement.

         Section 2. Restrictions on Transfer. The Holder acknowledges and
understands that prior to the registration of the Securities as provided herein,
the Securities are "restricted securities" as defined in Rule 144 promulgated
under the Act. The Holder understands that no disposition or transfer of the
Securities may be made by Holder in the absence of (i) an opinion of counsel to
the Holder that such transfer may be made without registration under the 1933
Act or (ii) such registration.

                                       1
<PAGE>   57

         With a view to making available to the Holder the benefits of Rule 144
under the Securities Act or any other similar rule or regulation of the
Commission that may at any time permit the Holder to sell securities of the
Company to the public without registration ("Rule 144"), the Company agrees to:

               (a)    comply with the provisions of paragraph (c)(1) of Rule
144; and

               (b)    file with the Commission in a timely manner all reports
and other documents required to be filed by the Company pursuant to Section 13
or 15(d) under the Exchange Act; and, if at any time it is not required to file
such reports but in the past had been required to or did file such reports, it
will, upon the request of any Holder, make available other information as
required by, and so long as necessary to permit sales of, its Registrable
Securities pursuant to Rule 144.

         Section 3. Registration Rights.

               (a)    The Company agrees that it will prepare and file with the
Securities and Exchange Commission ("Commission"), within 45 days after the date
hereof, a registration statement on Form S-3 (or other appropriate form of
registration statement) under the 1933 Act (the "Registration Statement"), at
the sole expense of the Company (except as provided in Section 3(c) hereof), in
respect of all holders of Registrable Securities, so as to permit a public
offering and resale of the Registrable Securities under the Act.

                      The Company shall use its best efforts to cause the
Registration Statement to become effective, not later than 90 days after the
date hereof, or if the Commission notifies the Company that it will not review
the Registration Statement, not later than ten business days thereafter. The
number of shares designated in the Registration Statement to be registered shall
include all the Warrant Shares and the number of shares of Common Stock which
would be issued assuming a Market Price of $1.00 per share of Common Stock, and
shall include appropriate language regarding reliance upon Rule 416 to the
extent permitted by the Commission. The Company will notify Holder of the
effectiveness of the Registration Statement within one business day of such
event. The number of Registrable Securities that the Holder may sell under the
Registration Statement may not exceed that number of shares of Common Stock
which the Selling Securityholder section of the Registration Statement states
are to be offered by the Holder.

               (b)    The Company will maintain the Registration Statement or
post-effective amendment filed under this Section 3 hereof current under the
1933 Act until the earlier of (i) the date that all of the Registrable
Securities have been sold pursuant to the Registration Statement, (ii) the date
the holders thereof receive an opinion of counsel to the Company, which counsel
shall be reasonably acceptable to the Holder, that all Registrable Securities
may be sold under the provisions of Rule 144 without limitation as to volume,
(iii) all Registrable Securities have been otherwise transferred to Holders who
may trade such shares without restriction under the Securities Act, and the
Company has delivered a new certificate or other evidence of ownership for such
securities not bearing a restrictive legend, or (iv) all Registrable Securities
may be sold without any time, volume or manner limitations pursuant to Rule
144(k) or any similar provision then in effect under the

                                       2
<PAGE>   58

Securities Act in the opinion of counsel to the Company, which counsel shall be
reasonably acceptable to the Holder.

               (c)    All fees, disbursements and out-of-pocket expenses and
costs incurred by the Company in connection with the preparation and filing of
the Registration Statement under subparagraph 3(a) and in complying with
applicable securities and Blue Sky laws (including, without limitation, all
attorneys' fees) shall be borne by the Company. The Holder shall bear the cost
of underwriting discounts and commissions, if any, applicable to the Registrable
Securities being registered and the fees and expenses of its counsel. The Holder
and its counsel shall have a reasonable period, not to exceed three (3) business
days, to review the proposed Registration Statement or any amendment thereto,
prior to filing with the Commission, and the Company shall provide each Holder
with copies of any comment letters received from the Commission with respect
thereto. The Company shall make reasonably available for inspection by Holder,
any underwriter participating in any disposition pursuant to the Registration
Statement, and any attorney, accountant or other agent retained by such Holder
or any such underwriter all relevant financial and other records, pertinent
corporate documents and properties of the Company and its subsidiaries, and
cause the Company's officers, directors and employees to supply all information
reasonably requested by such Holder or any such underwriter, attorney,
accountant or agent in connection with the Registration Statement, in each case,
as is customary for similar due diligence examinations; provided, however, that
all records, information and documents that are designated in writing by the
Company, in good faith, as confidential, proprietary or containing any material
non-public information shall be kept confidential by such Holder and any such
underwriter, attorney, accountant or agent (pursuant to an appropriate
confidentiality agreement in the case of any such Holder or agent), unless such
disclosure is made pursuant to judicial process in a court proceeding (after
first giving the Company an opportunity promptly to seek a protective order or
otherwise limit the scope of the information sought to be disclosed) or is
required by law, or such records, information or documents become available to
the public generally or through a third party not in violation of an
accompanying obligation of confidentiality; and provided further that, if the
foregoing inspection and information gathering would otherwise disrupt the
Company's conduct of its business, such inspection and information gathering
shall, to the maximum extent possible, be coordinated on behalf of the Holder
and the other parties entitled thereto by one firm of counsel designed by and on
behalf of the majority in interest of Holder and other parties. The Company
shall qualify any of the securities for sale in such states as such Holder
reasonably designates and shall furnish indemnification in the manner provided
in Section 6 hereof. However, the Company shall not be required to qualify in
any state which will require an escrow or other restriction relating to the
Company and/or the sellers. The Company at its expense will supply the Holder
with copies of the Registration Statement and the prospectus or offering
circular included therein and other related documents in such quantities as may
be reasonably requested by the Holder.

               (d)    The Company shall not be required by this Section 3 to
include a Holder's Registrable Securities in any Registration Statement which is
to be filed if, in the opinion of counsel for both the Holder and the Company
(or, should they not agree, in the opinion of another counsel experienced in
securities law matters acceptable to counsel for the Holder and the Company) the
proposed offering or other transfer as to which such registration is requested
is exempt from

                                       3
<PAGE>   59

applicable federal and state securities laws and would result in all purchasers
or transferees obtaining securities which are not "restricted securities", as
defined in Rule 144 under the 1933 Act.

               (e)    In the event that (i) the Registration Statement to be
filed by the Company pursuant to Section 3(a) above is not filed with the
Commission within 45 days after the date hereof, or the Registration Statement
is not declared effective by the Commission not later than 90 days after the
date hereof, or if the Commission notifies the Company that it will not review
the Registration Statement and the Registration Statement is not declared
effective not later than ten (10) business days thereafter, (ii) the
Registration Statement is not maintained as effective by the Company for the
period set forth in Section 3(b) above or (iii) an amendment to the Registration
Statement was not filed by the Company with the Commission and declared
effective by the Commission on a timely basis to include any additional number
of Registrable Securities as described in Section 3(i), if necessary, then the
Company will pay Holder (pro rated on a daily basis), as liquidated damages for
such failure and not as a penalty, two (2%) percent of the purchase price of the
then outstanding shares of Preferred Stock for the first thirty (30) days, and
in the event of late filing, three percent (3%) percent of the purchase price of
the outstanding shares of Preferred Stock for every thirty (30) day period
thereafter until the Registration Statement has been filed and in the event of
late effectiveness, one percent (1%) of the purchase price of the outstanding
shares of Preferred Stock for every thirty (30) day period thereafter until the
Registration Statement has been declared effective. Such payment of the
liquidated damages shall be made to the Holder in cash, immediately upon demand,
provided, however, that the payment of such liquidated damages shall not relieve
the Company from its obligations to register the Registrable Securities pursuant
to this Section.

                      Notwithstanding the above, if the Registration Statement
covering the Additional Registrable Securities (as defined in Section 3(i)
hereof) required to be filed by the Company pursuant to Section 3(i) hereof is
not filed with the Commission within 45 days after the Market Price declines to
$1.00 or less for five consecutive Trading Days, the Company shall be in default
of this Registration Rights Agreement and the liquidated damages provisions of
the foregoing paragraph shall apply.

                      If the Company does not remit the damages to the Holder as
set forth above, the Company will pay the Holder reasonable costs of collection,
including attorneys fees, in addition to the liquidated damages. The
registration of the Securities pursuant to this provision shall not affect or
limit Holder's other rights or remedies as set forth in this Agreement.

               (f)    No provision contained herein shall preclude the Company
from selling securities pursuant to any Registration Statement in which it is
required to include Registrable Securities pursuant to this Section 3.

               (g)    If at any time or from time to time after the effective
date of the Registration Statement, the Company notifies the Holder in writing
of the existence of a Potential Material Event (as defined in Section 3(h)
below), the Holder shall not offer or sell any Registrable Securities or engage
in any other transaction involving or relating to Registrable Securities, from
the time of the giving of notice with respect to a Potential Material Event
until such Holder receives written notice

                                       4
<PAGE>   60

from the Company that such Potential Material Event either has been disclosed to
the public or no longer constitutes a Potential Material Event; provided,
however, that the Company may not so suspend the right to such holders of
Securities for more than twenty (20) days in the aggregate during any twelve
month period, during the periods the Registration Statement is required to be in
effect. If a Potential Material Event shall occur prior to the date the
Registration Statement is filed, then the Company's obligation to file the
Registration Statement shall be delayed without penalty for not more than twenty
(20) days. The Company must give Holder notice in writing at least two (2)
business days prior to the first day of the blackout period.

               (h)    "Potential Material Event" means any of the following: (a)
the possession by the Company of material information not ripe for disclosure in
a registration statement, which shall be evidenced by determinations in good
faith by the Chief Executive Officer or the Board of Directors of the Company
that disclosure of such information in the Registration Statement would be
detrimental to the business and affairs of the Company; or (b) any material
engagement or activity by the Company which would, in the good faith
determination of the Chief Executive Officer or the Board of Directors of the
Company, be adversely affected by disclosure in a registration statement at such
time, which determination shall be accompanied by a good faith determination by
the Chief Executive Officer or the Board of Directors of the Company that the
Registration Statement would be materially misleading absent the inclusion of
such information.

               (i)    In the event the Market Price declines to $1.00 or less
for five consecutive Trading Days (the "Decline Date"), the Company shall, to
the extent required by the Securities Act (because the additional shares were
not covered by the Registration Statement filed pursuant to Section 3(a)), file
an additional Registration Statement with the Commission for such additional
number of Registrable Securities issuable upon conversion of the Preferred Stock
(the "Additional Registrable Securities"), in addition to those previously
registered, as would be necessary to satisfy conversions of the then outstanding
shares of Preferred Stock based upon the then prevailing market price of the
Common Stock. The Company shall prepare and file with the Commission not later
than the 30th day after the Decline Date, a registration statement relating to
the offer and sale of such Additional Registrable Securities (the "Additional
Registration Statement") and shall use its best efforts to cause the Commission
to declare such Additional Registration Statement effective under the Securities
Act as promptly as practicable but not later than 60 days thereafter. If the
Additional Registration Statement is not (i) filed with the Commission by the
30th day after the Decline Date or (ii) declared effective by the Commission
within 90 days after the Decline Date (either of which, without duplication, an
"Additional Registration Date"), then the Company shall make payments to the
Holder as set forth in Section 3(e) hereof, for late filing or effectiveness, as
the case may be, relating to the Additional Securities.

         Section 4. Cooperation with Company. Holder will cooperate with the
Company in all respects in connection with this Agreement, including timely
supplying all information reasonably requested by the Company and executing and
returning all documents reasonably requested in connection with the registration
and sale of the Registrable Securities and entering into and performing its
obligations under any underwriting agreement, if the offering is an underwritten

                                       5
<PAGE>   61

offering, in usual and customary form, with the managing underwriter or
underwriters of such underwritten offering.

         Section 5. Registration Procedures. If and whenever the Company is
required by any of the provisions of this Agreement to effect the registration
of any of the Registrable Securities under the Act, the Company shall (except as
otherwise provided in this Agreement), as expeditiously as possible:

               (a)(i) prepare and file with the Commission such amendments
and supplements to the Registration Statement and the prospectus used in
connection therewith as may be necessary to keep such registration statement
effective and to comply with the provisions of the Act with respect to the sale
or other disposition of all securities covered by such registration statement
whenever the Holder of such securities shall desire to sell or otherwise dispose
of the same (including prospectus supplements with respect to the sales of
securities from time to time in connection with a registration statement
pursuant to Rule 415 promulgated under the Act) and (ii) take all lawful action
such that each of (A) the Registration Statement and any amendment thereto does
not, when it becomes effective, contain an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, not misleading and (B) the Prospectus forming part
of the Registration Statement, and any amendment or supplement thereto, does not
at any time during the Registration Period include an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

               (b)(i) prior to the filing with the Commission of any
Registration Statement (including any amendments thereto) and the distribution
or delivery of any prospectus (including any supplements thereto), provide draft
copies thereof to the Holders and reflect in such documents all such comments as
the Holders (and their counsel) reasonably may propose respecting the Selling
Shareholders and Plan of Distribution sections (or equivalents) and (ii) furnish
to each Holder such numbers of copies of a prospectus including a preliminary
prospectus or any amendment or supplement to any prospectus, in conformity with
the requirements of the Act, and such other documents, as such Holder may
reasonably request in order to facilitate the public sale or other disposition
of the securities owned by such Holder;

               (c)    register and qualify the securities covered by the
Registration Statement under such other securities or blue sky laws of such
jurisdictions as the Holder shall reasonably request (subject to the limitations
set forth in Section 3(d) above), and do any and all other acts and things which
may be necessary or advisable to enable each Holder to consummate the public
sale or other disposition in such jurisdiction of the securities owned by such
Holder, except that the Company shall not for any such purpose be required to
qualify to do business as a foreign corporation in any jurisdiction wherein it
is not so qualified or to file therein any general consent to service of
process;

               (d)    list such securities on The Nasdaq SmallCap Market or
other national securities exchange on which any securities of the Company are
then listed, if the listing of such securities is then permitted under the rules
of such exchange or Nasdaq;

               (e)    enter into and perform its obligations under an
underwriting agreement, if the offering is an underwritten offering, in usual
and customary form, with the managing underwriter or underwriters of such
underwritten offering, including, but not limited to, the following:

                      (i) making such representations and warranties to the
Holder participating in such underwritten offering and to the managers, in form,
substance and scope as are customarily made by the Company to underwriters in
secondary underwritten offerings;

                      (ii) obtaining opinions of counsel to the Company (which
counsel and opinions (in form, scope and substance) shall be reasonably
satisfactory to the managers) addressed to the underwriters, covering such
matters as are customarily covered in opinions requested in secondary
underwritten offerings (it being agreed that the matters to be covered by such
opinions shall include, without limitation, as of the date of the opinion and as
of the Effective Time of the Registration Statement or most recent
post-effective amendment thereto, as the case may be, the absence from the
Registration Statement and the Prospectus, including any documents incorporated
by reference therein, of an untrue statement of a material fact or the omission
of a material fact required to be stated therein or necessary to make the
statements therein (in the case of the Prospectus, in light of the circumstances
under which they were made) not misleading, subject to customary limitations);

                      (iii) obtaining "cold comfort" letters and updates thereof
from the independent public accountants of the Company (and, if necessary, from
the independent public accountants of any subsidiary of the Company or of any
business acquired by the Company, in each case for which financial statements
and financial data are, or are required to be, included in the Registration
Statement), addressed to each underwriter participating in such underwritten
offering (if such underwriter has provided such letter, representations or
documentation, if any, required for such cold comfort letter to be so
addressed), in customary form and covering matters of the type customarily
covered in "cold comfort" letters in connection with secondary underwritten
offerings; and

                      (iv) delivering such documents and certificates as may be
reasonably required by the managers, if any;

               (f)    notify each Holder of Registrable Securities covered by
the Registration Statement, at any time when a prospectus relating thereto
covered by the Registration Statement is required to be delivered under the Act,
of the happening of any event of which it has knowledge as a result of which the
prospectus included in the Registration Statement, as then in effect, includes
an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances then existing, and the Company
shall prepare and file a curative amendment under Section 5(a) as quickly as
commercially possible;

               (g)    as promptly as practicable after becoming aware of such
event, notify each Holder who holds Registrable Securities being sold (or, in
the event of an underwritten offering, the managing underwriters) of the
issuance by the Commission of any stop order or other suspension

                                       7
<PAGE>   63

of the effectiveness of the Registration Statement at the earliest possible time
and take all lawful action to effect the withdrawal, recession or removal of
such stop order or other suspension;

               (h)    cooperate with the Holders who hold Registrable Securities
being offered to facilitate the timely preparation and delivery of certificates
for the Registrable Securities to be offered pursuant to the Registration
Statement and enable such certificates for the Registrable Securities to be in
such denominations or amounts, as the case may be, as the Holders reasonably may
request and registered in such names as the Holder may request; and, within
three business days after a Registration Statement which includes Registrable
Securities is declared effective by the Commission, deliver and cause legal
counsel selected by the Company to deliver to the transfer agent for the
Registrable Securities (with copies to the Holders whose Registrable Securities
are included in such Registration Statement) an appropriate instruction and, to
the extent necessary, an opinion of such counsel;

               (i)    take all such other lawful actions reasonably necessary to
expedite and facilitate the disposition by the Holders of their Registrable
Securities in accordance with the intended methods therefor provided in the
prospectus which are customary under the circumstances;

               (j)    make generally available to its security holders as soon
as practicable, but in any event not later than 18 months after (i) the
effective date (as defined in Rule 158(c) under the Securities Act) of the
Registration Statement, and (ii) the effective date of each post-effective
amendment to the Registration Statement, as the case may be, an earnings
statement of the Company and its subsidiaries complying with Section 11(a) of
the Securities Act and the rules and regulations of the commission thereunder
(including, at the option of the Company, Rule 158);

               (k)    in the event of an underwritten offering, promptly include
or incorporate in a Prospectus supplement or post-effective amendment to the
Registration Statement such information as the managers reasonably agree should
be included therein and to which the Company does not reasonably object and make
all required filings of such Prospectus supplement or post-effective amendment
as soon as practicable after it is notified of the matters to be included or
incorporated in such Prospectus supplement or post-effective amendment; and

               (l)    maintain a transfer agent and registrar for its Common
Stock.

         Section 6.  Indemnification.

               (a)    The Company agrees to indemnify and hold harmless the
Holder and each person, if any, who controls the Holder within the meaning of
the 1933 Act ("Distributing Holder") against any losses, claims, damages or
liabilities, joint or several (which shall, for all purposes of this Agreement,
include, but not be limited to, all reasonable costs of defense and
investigation and all reasonable attorneys' fees), to which the Distributing
Holder may become subject, under the 1933 Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in the Registration Statement, or any related
preliminary prospectus, final prospectus,

                                       8
<PAGE>   64

offering circular, notification or amendment or supplement thereto, or arise out
of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading; provided, however, that the Company will not be liable
in any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in the Registration Statement, preliminary
prospectus, final prospectus, offering circular, notification or amendment or
supplement thereto in reliance upon, and in conformity with, written information
furnished to the Company by the Distributing Holder, specifically for use in the
preparation thereof. This Section 6(a) shall not inure to the benefit of any
Distributing Holder with respect to any person asserting such loss, claim,
damage or liability who purchased the Registrable Securities which are the
subject thereof if the Distributing Holder failed to send or give (in violation
of the 1933 Act or the rules and regulations promulgated thereunder) a copy of
the prospectus contained in such Registration Statement to such person at or
prior to the written confirmation to such person of the sale of such Registrable
Securities, where the Distributing Holder was obligated to do so under the 1933
Act or the rules and regulations promulgated thereunder.

               (b)    Each Distributing Holder agrees that it will indemnify and
hold harmless the Company, and each officer, director of the Company or person,
if any, who controls the Company within the meaning of the 1933 Act, against any
losses, claims, damages or liabilities (which shall, for all purposes of this
Agreement, include, but not be limited to, all reasonable costs of defense and
investigation and all reasonable attorneys' fees) to which the Company or any
such officer, director or controlling person may become subject under the 1933
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof; arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in the Registration
Statement, or any related preliminary prospectus, final prospectus, offering
circular, notification or amendment or supplement thereto, or arise out of or
are based upon the omission or the alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, but in each case only to the extent that such untrue statement
or alleged untrue statement or omission or alleged omission was made in the
Registration Statement, preliminary prospectus, final prospectus, offering
circular, notification or amendment or supplement thereto in reliance upon, and
in conformity with, written information furnished to the Company by such
Distributing Holder, specifically for use in the preparation thereof.

               (c)    Promptly after receipt by an indemnified party under this
Section 6 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 6, notify the indemnifying party of the commencement thereof;
but the omission so to notify the indemnifying party will not relieve the
indemnifying party from any liability which it may have to any indemnified party
except to the extent of actual prejudice demonstrated by the indemnifying party.
In case any such action is brought against any indemnified party, and it
notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate in, and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified, assume the defense
thereof, subject to the provisions herein stated and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such

                                       9
<PAGE>   65

indemnified party under this Section 6 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation, unless the indemnifying
party shall not pursue the action to its final conclusion. The indemnified party
shall have the right to employ separate counsel in any such action and to
participate in the defense thereof, but the fees and expenses of such counsel
shall not be at the expense of the indemnifying party if the indemnifying party
has assumed the defense of the action with counsel reasonably satisfactory to
the indemnified party; provided that if the indemnified party is the
Distributing Holder, the fees and expenses of such counsel shall be at the
expense of the indemnifying party if (i) the employment of such counsel has been
specifically authorized in writing by the indemnifying party, or (ii) the named
parties to any such action (including any impleaded parties) include both the
Distributing Holder and the indemnifying party and the Distributing Holder shall
have been advised by such counsel that there may be one or more legal defenses
available to the indemnifying party different from or in conflict with any legal
defenses which may be available to the Distributing Holder (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the Distributing Holder, it being understood, however, that the
indemnifying party shall, in connection with any one such action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable only for the reasonable
fees and expenses of one separate firm of attorneys for the Distributing Holder,
which firm shall be designated in writing by the Distributing Holder). No
settlement of any action against an indemnified party shall be made without the
prior written consent of the indemnified party, which consent shall not be
unreasonably withheld.

         Section 7. Contribution. In order to provide for just and equitable
contribution under the 1933 Act in any case in which (i) the indemnified party
makes a claim for indemnification pursuant to Section 6 hereof but is judicially
determined (by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last
right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that the express provisions of Section 6 hereof provide
for indemnification in such case, or (ii) contribution under the 1933 Act may be
required on the part of any indemnified party, then the Company and the
applicable Distributing Holder shall contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (which shall, for all
purposes of this Agreement, include, but not be limited to, all reasonable costs
of defense and investigation and all reasonable attorneys' fees), in either such
case (after contribution from others) on the basis of relative fault as well as
any other relevant equitable considerations. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company on the one hand
or the applicable Distributing Holder on the other hand, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company and the Distributing Holder
agree that it would not be just and equitable if contribution pursuant to this
Section 7 were determined by pro rata allocation or by any other method of
allocation which does not take account of the equitable considerations referred
to in this Section 7. The amount paid or payable by an indemnified party as a
result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to above in this Section 7 shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in

                                       10
<PAGE>   66

connection with investigating or defending any such action or claim. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the 1933 Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

               Notwithstanding any other provision of this Section 7, in no
event shall any (i) Holder be required to undertake liability to any person
under this Section 7 for any amounts in excess of the dollar amount of the
proceeds to be received by such Holder from the sale of such Holder's
Registrable Securities (after deducting any fees, discounts and commissions
applicable thereto) pursuant to any Registration Statement under which such
Registrable Securities are to be registered under the Securities Act and (ii)
underwriter be required to undertake liability to any person hereunder for any
amounts in excess of the aggregate discount, commission or other compensation
payable to such underwriter with respect to the Registrable Securities
underwritten by it and distributed pursuant to the Registration Statement.

         Section 8.   Notices. All notices, demands, requests, consents,
approvals, and other communications required or permitted hereunder shall be in

(ii) deposited in the mail, registered or certified, return receipt requested,

         Section 9. Assignment. This Agreement is binding upon and inures to the
benefit of the parties hereto and their respective heirs, successors and
permitted assigns. The rights granted the Holder under this Agreement may be
assigned to any purchaser of substantially all of the Registrable Securities (or
the rights thereto) from Holder. In the event of a transfer of the rights
granted under this Agreement, the Holder agrees that the Company may require
that the transferee comply with reasonable conditions as determined in the
discretion of the Company.

         Section 10. Additional Covenants of the Company. The Company agrees

two or more counterparts, each of which shall be constitute an original, but all
of which, when together shall constitute but one and the same instrument, and
shall become effective when one or more counterparts have been signed by each
party hereto and delivered to the other party. In lieu of the original, a
facsimile transmission or copy of the original shall be as effective and
enforceable as the original.

         Section 12.  Termination of Registration Rights. The rights granted
pursuant to this Agreement shall terminate as to each Holder (and permitted
transferees or assignees ) upon the occurrence of any of the following:

               (a)    all Holder's securities subject to this Agreement have
been registered and sold; or

               (b)    such Holder's securities subject to this Agreement may be

         Section 13. Remedies. The remedies provided in this Agreement are
cumulative and not exclusive of any remedies provided by law. If any term,
provision, covenant or restriction of this Agreement is held by a court of
competent jurisdiction to be invalid, illegal, void or unenforceable, the

or invalidated, and the parties hereto shall use their best efforts to find and
employ an alternative means to achieve the same or substantially the same result

interest of the Registrable Securities, the Company shall not grant to any
person the right to request it to register any of its securities under the
Securities Act unless the rights so granted are subject in all respect to the
prior rights of the holders of Registrable Securities set forth herein, and are
not otherwise in conflict or inconsistent with the provisions of this Agreement.
The restrictions on the Company's rights to grant registration rights under this
paragraph shall terminate on the date of the Registration Statement to be filed
pursuant to Section 3(a) is declared effective by the Commission.

         Section 15. Headings.  The headings in this Agreement are for reference

authorized by this Section 17, whether or not such Registrable Securities shall
have been marked to indicate such consent.

         We have acted as counsel to the Company in connection with the
negotiation of the Purchase Agreement, the Warrant and the Registration Rights
Agreement between the Investors and the Company, dated as of February 8, 2000
(the "Registration Rights Agreement", and together with the Purchase Agreement,
the "Agreements"). As such counsel, we have made such legal and factual
examinations and inquiries as we have deemed advisable or necessary for the
purpose of rendering this opinion. In addition, we have examined, among other
things, originals or copies of such corporate records of the Company,
certificates of public officials and such other documents and questions of law
that we consider necessary or advisable for the purpose of rendering this
opinion. In such examination we have assumed the genuineness of all signatures
on original documents, the authenticity and completeness of all documents
submitted to us as originals, the conformity to original documents of all copies
submitted to us as copies thereof, the legal capacity of natural persons, and
the due execution and delivery of all documents (except as to due execution and
delivery by the Company) where due execution and delivery are a prerequisite to
the effectiveness thereof. As to the matters of fact, we have relied upon
certificates or other written statements of public authorities and certificates
or other written statements of officers and directors of the Company. The
phrases "to our knowledge" or "known to us" when used herein mean that with
respect to the factual matter covered thereby, we have undertaken no independent
investigation or verification of such matters, but have relied solely

<PAGE>   71

upon the representations and warranties of the Company contained in the
Agreements and have obtained certificates from the officers and directors of the
Company as to such factual matters, and nothing has come to the attention of
those attorneys in our office who directly participated in this engagement that
(x) would give them actual knowledge or actual notice that such representation
or warranty is not accurate or complete, or (y) any information set forth in any
of the foregoing documents, certificates and information on which they have
relied is not accurate or complete. In addition, we have assumed that any
certificate of a public authority on which we have relied that was given or
dated earlier than the date of this opinion continues to remain accurate,
insofar as relevant to such opinion, from such earlier date through and
including the date of this opinion.

         For purposes of this opinion, we have assumed that each Investor has
all requisite power and authority, and has taken any and all necessary corporate
action, to execute and deliver the Agreements, and we are assuming that the
representations and warranties made by the Investors in the Agreements and
pursuant thereto are true and correct.

         Based upon and subject to the foregoing, we are of the opinion that:

         1.    The Company is a corporation duly organized, validly existing and
in good standing under the laws of the State of Delaware and has all requisite
corporate power and authority to carry on its business and to own, lease and
operate its properties and assets as described in the Company's SEC Documents.
To our knowledge, the Company does not have any subsidiaries and does not own
more than fifty percent (50%) of the outstanding capital stock of or control any
other business entity other than as disclosed in the SEC Documents. The Company
is duly qualified as a foreign corporation to do business and is in good
standing in every jurisdiction in which the Company owns or leases property,
other than those in which the failure so to qualify would not have a Material
Adverse Effect.

         2.    The Company has the requisite corporate power and authority to
enter into and perform its obligations under the Agreements and the Warrant and
to issue the Preferred Stock, the Conversion Shares, the Warrant and the Warrant
Shares. The execution and delivery of the Agreements by the Company and the
consummation by it of the transactions contemplated thereby have been duly
authorized by all necessary corporate action and no further consent or
authorization of the Company or its Board of Directors or stockholders is
required, except as may be required under the rules of the Nasdaq Stock Market,
Inc., as contemplated by the terms of the Preferred Stock (the "Nasdaq
Restriction"). Each of the Agreements has been duly executed and delivered and
the Preferred Stock and the Warrant have each been duly executed, issued and
delivered by the Company and each of the Agreements and the Warrant constitutes
valid and binding obligations of the Company enforceable against the Company in
accordance with their respective terms, except as such enforceability may be
limited by applicable bankruptcy, insolvency, or similar laws relating to, or
affecting generally the enforcement of, creditors' rights and remedies or by
other equitable principles of general application.

                                       2
<PAGE>   72

         3.    The execution, delivery and performance of the Agreements by the
Company and the consummation by the Company of the transactions contemplated
thereby, including, without limitation, the issuance of the Preferred Stock, the
Conversion Shares, the Warrant and the Warrant Shares, do not and will not (i)
result in a violation of the Company's Certificate of Incorporation or By-Laws;
(ii) to our knowledge, conflict with, or constitute a material default (or an
event that with notice or lapse of time or both would become a default) under,
or give to others any rights of termination, amendment, acceleration or
cancellation of, any material agreement, indenture, instrument or any "lock-up"
or similar provision of any underwriting or similar agreement to which the
Company is a party; or (iii) result in a violation of any federal or state law,
rule or regulation applicable to the Company or by which any property or asset
of the Company is bound or affected, except for such violations as would not,
individually or in the aggregate, have a Material Adverse Effect. To our
knowledge, the Company is not in violation of any terms of its Certificate of
Incorporation or Bylaws.

         4.    The issuance of the Preferred Stock, the Conversion Shares and
the Warrant in accordance with the Purchase Agreement, and the issuance of the
Warrant Shares in accordance with the Warrant, will be exempt from registration
under the Securities Act of 1933, as amended. When so issued, the Preferred
Stock, the Conversion Shares and the Warrant Shares will be duly and validly
issued, fully paid and nonassessable, and free of any liens, encumbrances and
preemptive or similar rights contained in the Company's Certificate of
Incorporation or Bylaws or, to our knowledge, in any agreement to which the
Company is party.

         5.    To our knowledge, there are no claims, actions, suits,
proceedings or investigations that are pending against the Company or its
properties, or against any officer or director of the Company in his or her
capacity as such, nor has the Company received any written threat of any such
claims, actions, suits, proceedings, or investigations which could reasonably be
expected to have a Material Adverse Effect. To our knowledge, the Company is not
a party to or subject to the provisions of any order, writ, injunction, judgment
or decree of any court or government agency or instrumentality.

         6.    To our knowledge, there are no outstanding options, warrants,
calls or commitments of any character whatsoever relating to, or securities,
rights or obligations convertible into or exchangeable for, or giving any right
to subscribe for or acquire any shares of Common Stock or contracts,
commitments, understandings, or arrangements by which the Company is or may
become bound to issue additional shares of Common Stock, or securities or rights
convertible or exchangeable into shares of Common Stock, except as described in
the SEC Documents.

         7.    Subject to compliance with the Nasdaq Restriction if and when the
same shall apply, the issuance of the Preferred Stock, the Conversion Shares and
the Warrant Shares will not violate the applicable listing agreement between the
Company and any securities exchange or market on which the Company's securities
are listed.

                                       3

         8.    The authorized capital stock of the Company consists of
50,000,000 shares of Common Stock, $0.01 par value per share, and 1,000,000
shares of Preferred Stock, $0.01 par value per share, of which 3,520 shares have
been properly designated as Series A Convertible Preferred Stock, 1,000 shares
have been properly designated as Series B Convertible Preferred Stock, 750
shares have been properly designated as Series C Convertible Preferred Stock,
2,000 shares have been properly designated as Series D Convertible Preferred
Stock, 3,000 shares have been properly designated as Series E Convertible
Preferred Stock, and 2,000 have been properly designated as Series F Convertible
Preferred Stock.

               This opinion is limited to the Federal laws of the United States,
the laws of the State of New York and the Delaware General Corporation Law. No
opinion is expressed with respect to the laws, rules or regulations of any other
jurisdiction, whether U.S. or foreign.

               This opinion is furnished to the Investors solely for its benefit
in connection with the transactions described above and may not be relied upon
by any other person or for any other purpose without our prior written consent.

                                      Very truly yours,

                                      SNOW BECKER KRAUSS P.C.

American Stock Transfer and Trust Company

Attn: Barry Rosenthal

Dear Sirs:

Reference is made to the Preferred Stock Purchase Agreement and all Exhibits
thereto (the "Agreement") dated as of February , 2000, between the Investors
named therein and Integrated Surgical Systems, Inc. (the "Company"). Pursuant to
the Agreement, and subject to the terms and conditions set forth in the
Agreement, the Investors have agreed to purchase from the Company, and the
Company has agreed to sell to the Investors, shares of Series F Convertible
Preferred Stock of the Company, par value $0.01 per share (the "Preferred
Stock"), and the Company has issued to the Investors (i) 2,000 shares of Series
F Convertible Preferred Stock of the Company, par value $0.01 per share, and
(ii) a warrant to purchase 125,000 shares of Common Stock (the "Warrant"). As a
condition to the effectiveness of the Agreement, the Company has agreed to issue
to you, as the transfer agent for the Common Stock (the "Transfer Agent"), these
instructions relating to the Common Stock to be issued to the Investor (or a
permitted assignee) pursuant to the Agreement upon conversion of the Preferred
Stock or upon exercise of the Warrant. All terms used herein and not otherwise
defined shall have the meaning set forth in the Agreement.

1.       ISSUANCE  OF COMMON STOCK WITHOUT THE LEGEND

         Pursuant to the Agreement, the Company is required to prepare and file
with the Commission, and maintain the effectiveness of, a registration statement
or registration statements registering the resale of the Common Stock to be
acquired by the Investor (i) upon exercise of the Warrant and (ii) upon
conversion of the Series F Convertible Preferred Stock. The Company will advise
the Transfer Agent in writing of the effectiveness of any such registration
statement promptly upon its being declared effective. The Transfer Agent shall
be entitled to rely on such advice and shall assume that the effectiveness of
such registration statement remains in effect unless the Transfer Agent is
otherwise advised in writing by the Company and shall not be required to
independently confirm the continued effectiveness of such registration
statement. In the circumstances set forth in the following two paragraphs, the
Transfer Agent shall deliver to the Investor certificates representing Common
Stock not bearing the Legend without requiring further advice or instruction or
additional documentation from the Company or its counsel or the Investor or its
counsel or any other party (other than as described in such paragraphs).

         (a)   In the event the Company files a Form S-3 or Form S-1, S-2 or
SB-2 registration statement and such registration statement is declared
effective by the Securities and Exchange

<PAGE>   75

Commission in connection with any such event, the Investor (or its permitted
assignee) shall confirm in writing to the Transfer Agent that (i) the Investor
has sold, pledged or otherwise transferred or agreed to sell, pledge or
otherwise transfer such Common Stock in a bona fide transaction to a third party
that is not an affiliate of the Company; and (ii) the Investor confirms to the
transfer agent that the Investor has complied with the prospectus delivery
requirement.

         (b)   In the event a registration statement is not filed by the
Company, or for any reason the registration statement which is filed by the
Company is not declared effective by the Securities and Exchange Commission the
Investor, or its permitted assignee, or either of their brokers confirms to the
Transfer Agent that (i) the Investor has beneficially owned the shares of Common
Stock for at least one year, (ii) counting the shares surrendered as being sold
upon the date the unlegended Certificates would be delivered to the Investor (or
the Trading Day immediately following if such date is not a Trading Day), the
Investor will not have sold more than the greater of (a) one percent (1%) of the
total number of outstanding shares of Common Stock or (b) the average weekly
trading volume of the Common Stock for the preceding four weeks during the three
months ending upon such delivery date (or the Trading Day immediately following
if such date is not a Trading Day), and (iii) the Investor has complied with the
manner of sale and notice requirements of Rule 144 under the Securities Act.

Any advice, notice, or instructions to the Transfer Agent required or permitted
to be given hereunder may be transmitted via facsimile to the Transfer Agent's
facsimile number of (718) 259-1144.

2.       MECHANICS OF DELIVERY OF CERTIFICATES REPRESENTING COMMON STOCK

In connection with any conversion of Preferred Stock or exercise of a Warrant
pursuant to which the Investor acquires Common Stock under the Agreement, the
Transfer Agent shall deliver to the Investor, certificates representing Common
Stock (with or without the Legend, as appropriate) immediately upon request of
the Company, and, if the Transfer Agent is able to deliver such Common Stock to
the Investor's account pursuant to the DWAC system of the Depository Trust
Company, the Transfer Agent shall make delivery pursuant to such system and
provide the Investor with confirmation thereof in lieu of such Common Stock
certificates.

3.       FEES OF TRANSFER AGENT; INDEMNIFICATION

The Company agrees to pay the Transfer Agent for all fees incurred in connection
with these Irrevocable Instructions. The Company agrees to indemnify the
Transfer Agent and its officers, employees and agents, against any losses,
claims, damages or liabilities, joint or several, to which it or they become
subject based upon the performance by the Transfer Agent of its duties in
accordance with the Irrevocable Instructions.
