                              GISH BIOMEDICAL, INC.

                             STOCK OPTION AGREEMENT
                             ----------------------

   TYPE OF OPTION (CHECK ONE):  [ ]   INCENTIVE         [ ] NONQUALIFIED


        This Stock Option Agreement (the "Agreement") is entered into as of
___________ , 19__, by and between Gish Biomedical, Inc., a California 
corporation (the "Company"), and ______________________________________________
(the "Optionee") pursuant to the Company's 1997 Stock Incentive Plan 
(the "Plan").

        1. GRANT OF OPTION. The Company hereby grants to Optionee an option (the
"Option") to purchase all or any portion of a total of ______________________
(      ) shares (the "Shares") of the Common Stock of the Company at a purchase
price of _________________________________________ ($___________) per share 
(the "Exercise Price"), subject to the terms and conditions set
forth herein and the provisions of the Plan. If the box marked "Incentive" above
is checked, then this Option is intended to qualify as an "incentive stock
option" as defined in Section 422 of the Internal Revenue Code of l986, as
amended (the "Code"). If this Option fails in whole or in part to qualify as an
incentive stock option, or if the box marked "Nonqualified" is checked, then
this Option shall to that extent constitute a nonqualified stock option.

        2. VESTING OF OPTION. The right to exercise this Option shall vest in
installments, and this Option shall be exercisable from time to time in whole or
in part as to any vested installment, as follows:

                                                        This Option shall be
               On or After:                             Exercisable as to:
               ------------                             --------------------

        (i)   ___________________, 19___:                _______________ shares

        (ii)  ___________________, 19___: an additional  _______________ shares

        (iii) ___________________, 19___: an additional  _______________ shares

        (iv)  ___________________, 19___: an additional  _______________ shares

No additional shares shall vest after the date of termination of Optionee's
"Continuous Service" (as defined in Section 3 below), but this Option shall
continue to be exercisable in accordance with Section 3 hereof with respect to
that number of shares that have vested as of the date of termination of
Optionee's Continuous Service.

        3. TERM OF OPTION. Optionee's right to exercise this Option shall
terminate upon the first to occur of the following:

            (a) the expiration of ____ (___) years from the date of this
Agreement;

            (b) the expiration of three (3) months from the date of termination
of Optionee's 



   2

Continuous Service if such termination occurs for any reason other than
permanent disability, death or voluntary resignation; provided, however, that if
Optionee dies during such three-month period the provisions of Section 3(e)
below shall apply;

            (c) the expiration of one (1) month from the date of termination of
Optionee's Continuous Service if such termination occurs due to voluntary
resignation; provided, however, that if Optionee dies during such one-month
period the provisions of Section 3(e) below shall apply;

            (d) the expiration of one (1) year from the date of termination of
Optionee's Continuous Service if such termination is due to permanent disability
of the Optionee (as defined in Section 22(e)(3) of the Code);

            (e) the expiration of one (1) year from the date of termination of
Optionee's Continuous Service if such termination is due to Optionee's death or
if death occurs during either the three-month or one-month period following
termination of Optionee's Continuous Service pursuant to Section 3(b) or 3(c)
above, as the case may be; or

            (f) upon the consummation of a "Change in Control" (as defined in
Section 2.4 of the Plan), unless otherwise provided pursuant to Section 9 below.

        As used herein, the term "Continuous Service" means (i) employment by
either the Company or any parent or subsidiary corporation of the Company, or by
a corporation or a parent or subsidiary of a corporation issuing or assuming a
stock option in a transaction to which Section 424(a) of the Code applies, which
is uninterrupted except for vacations, illness (except for permanent disability,
as defined in Section 22(e)(3) of the Code), or leaves of absence which are
approved in writing by the Company or any of such other employer corporations,
if applicable, (ii) service as a member of the Board of Directors of the Company
until Optionee resigns, is removed from office, or Optionee's term of office
expires and he or she is not reelected, or (iii) so long as Optionee is engaged
as a consultant or service provider to the Company or other corporation referred
to in clause (i) above.

        4. EXERCISE OF OPTION. On or after the vesting of any portion of this
Option in accordance with Sections 2 or 9 hereof, and until termination of the
right to exercise this Option in accordance with Section 3 above, the portion of
this Option which has vested may be exercised in whole or in part by the
Optionee (or, after his or her death, by the person designated in Section 5
below) upon delivery of the following to the Company at its principal executive
offices:

            (a) a written notice of exercise which identifies this Agreement and
states the number of Shares then being purchased (but no fractional Shares may
be purchased);

            (b) a check or cash in the amount of the Exercise Price (or payment
of the Exercise Price in such other form of lawful consideration as the
Administrator may approve from time to time under the provisions of Section 5.3
of the Plan);

            (c) a check or cash in the amount reasonably requested by the
Company to satisfy the Company's withholding obligations under federal, state or
other applicable tax laws with respect to the taxable income, if any, recognized
by the Optionee in connection with the exercise of this Option (unless the
Company and Optionee shall have made other arrangements for deductions or
withholding from Optionee's wages, bonus or other compensation payable to
Optionee, or by the withholding of Shares issuable upon exercise of this Option
or the delivery of Shares owned by the Optionee in 



                                       2


   3

accordance with Section 10.1 of the Plan, provided such arrangements satisfy the
requirements of applicable tax laws); and

            (d) a letter, if requested by the Company, in such form and
substance as the Company may require, setting forth the investment intent of the
Optionee, or person designated in Section 5 below, as the case may be.

        5. DEATH OF OPTIONEE; NO ASSIGNMENT. The rights of the Optionee under
this Agreement may not be assigned or transferred except by will or by the laws
of descent and distribution, and may be exercised during the lifetime of the
Optionee only by such Optionee. Any attempt to sell, pledge, assign,
hypothecate, transfer or dispose of this Option in contravention of this
Agreement or the Plan shall be void and shall have no effect. If the Optionee's
Continuous Service terminates as a result of his or her death, and provided
Optionee's rights hereunder shall have vested pursuant to Section 2 hereof,
Optionee's legal representative, his or her legatee, or the person who acquired
the right to exercise this Option by reason of the death of the Optionee
(individually, a "Successor") shall succeed to the Optionee's rights and
obligations under this Agreement. After the death of the Optionee, only a
Successor may exercise this Option.

        6. REPRESENTATIONS AND WARRANTIES OF OPTIONEE.

            (a) Optionee represents and warrants that this Option is being
acquired by Optionee for Optionee's personal account, for investment purposes
only, and not with a view to the distribution, resale or other disposition
thereof.

            (b) Optionee acknowledges that the Company may issue Shares upon the
exercise of the Option without registering such Shares under the Securities Act
of l933, as amended (the "Securities Act"), on the basis of certain exemptions
from such registration requirement. Accordingly, Optionee agrees that his or her
exercise of the Option may be expressly conditioned upon his or her delivery to
the Company of an investment certificate including such representations and
undertakings as the Company may reasonably require in order to assure the
availability of such exemptions, including a representation that Optionee is
acquiring the Shares for investment and not with a present intention of selling
or otherwise disposing thereof and an agreement by Optionee that the
certificates evidencing the Shares may bear a legend indicating such
non-registration under the Securities Act and the resulting restrictions on
transfer. Optionee acknowledges that, because Shares received upon exercise of
an Option may be unregistered, Optionee may be required to hold the Shares
indefinitely unless they are subsequently registered for resale under the
Securities Act or an exemption from such registration is available.

            (c) Optionee acknowledges receipt of a copy of the Plan and
understands that all rights and obligations connected with this Option are set
forth in this Agreement and in the Plan.

        7. RESTRICTIVE LEGENDS. Optionee hereby acknowledges that federal
securities laws and the securities laws of the state in which Optionee resides
may require the placement of certain restrictive legends upon the Shares issued
upon exercise of this Option, and Optionee hereby consents to the placing of any
such legends upon certificates evidencing the Shares as the Company, or its
counsel, may deem necessary or advisable.

        8. ADJUSTMENTS UPON CHANGES IN CAPITAL STRUCTURE. In the event that the
outstanding shares of Common Stock of the Company are hereafter increased or
decreased or changed into or 



                                      3


   4

exchanged for a different number or kind of shares or other securities of the
Company by reason of a recapitalization, stock split, combination of shares,
reclassification, stock dividend or other change in the capital structure of the
Company, then appropriate adjustment shall be made by the Administrator to the
number of Shares subject to the unexercised portion of this Option and to the
Exercise Price per share, in order to preserve, as nearly as practical, but not
to increase, the benefits of the Optionee under this Option, in accordance with
the provisions of Section 4.2 of the Plan.

        9. CHANGE IN CONTROL. In the event of a Change in Control (as defined in
Section 2.4 of the Plan) of the Company, (i) the vesting of this Option pursuant
to Section 2 above shall automatically accelerate immediately prior to the
consummation of such Change in Control, and (ii) the Administrator in its
discretion may take one or more of the following actions: (A) provide for the
purchase or exchange of this Option for an amount of cash or other property
having a value equal to the difference, or spread, between (x) the value of the
cash or other property that the Optionee would have received pursuant to such
Change in Control transaction in exchange for the shares issuable upon exercise
of this Option had this Option been exercised immediately prior to such Change
in Control transaction and (y) the Exercise Price, (B) adjust the terms of this
Option in a manner determined by the Administrator to reflect the Change in
Control, (C) cause this Option to be assumed, or new rights substituted
therefor, by another entity, through the continuance of the Plan and the
assumption of this Option, or the substitution for this Option of a new option
of comparable value covering shares of a successor corporation, with appropriate
adjustments as to the number and kind of shares and Exercise Price, in which
event the Plan and this Option, or the new option substituted therefor, shall
continue in the manner and under the terms so provided, or (D) make such other
provision as the Administrator may consider equitable. If the Administrator does
not take any of the forgoing actions, this Option shall terminate upon the
consummation of the Change in Control and the Administrator shall cause written
notice of the proposed transaction to be given to the Optionee not less than
fifteen (15) days prior to the anticipated effective date of the proposed
transaction.

        10. NO EMPLOYMENT CONTRACT CREATED. Neither the granting of this Option
nor the exercise hereof shall be construed as granting to the Optionee any right
with respect to continuance of employment by the Company or any of its
subsidiaries. The right of the Company or any of its subsidiaries to terminate
at will the Optionee's employment at any time (whether by dismissal, discharge
or otherwise), with or without cause, is specifically reserved.

        11. RIGHTS AS SHAREHOLDER. The Optionee (or transferee of this option by
will or by the laws of descent and distribution) shall have no rights as a
shareholder with respect to any Shares covered by this Option until the date of
the issuance of a stock certificate or certificates to him or her for such
Shares, notwithstanding the exercise of this Option.

        12. "MARKET STAND-OFF" AGREEMENT. Optionee agrees that, if requested by
the Company or the managing underwriter of any proposed public offering of the
Company's securities, Optionee will not sell or otherwise transfer or dispose of
any Shares held by Optionee without the prior written consent of the Company or
such underwriter, as the case may be, during such period of time, not to exceed
180 days following the effective date of the registration statement filed by the
Company with respect to such offering, as the Company or the underwriter may
specify.

        13. INTERPRETATION. This Option is granted pursuant to the terms of the
Plan, and shall in all respects be interpreted in accordance therewith. The
Administrator shall interpret and construe this Option and the Plan, and any
action, decision, interpretation or determination made in good faith by the
Administrator shall be final and binding on the Company and the Optionee. As
used in this Agreement, 


                                       4


   5

the term "Administrator" shall refer to the committee of the Board of Directors
of the Company appointed to administer the Plan, and if no such committee has
been appointed, the term Administrator shall mean the Board of Directors.

        14. NOTICES. Any notice, demand or request required or permitted to be
given under this Agreement shall be in writing and shall be deemed given when
delivered personally or three (3) days after being deposited in the United
States mail, as certified or registered mail, with postage prepaid, and
addressed, if to the Company, at its principal place of business, Attention: the
Chief Financial Officer, and if to the Optionee, at his or her most recent
address as shown in the employment or stock records of the Company.

        15. ANNUAL AND OTHER PERIODIC REPORTS. During the term of this
Agreement, the Company will furnish to the Optionee copies of all annual and
other periodic financial and informational reports that the Company distributes
generally to its shareholders.

        16. GOVERNING LAW. The validity, construction, interpretation, and
effect of this Option shall be governed by and determined in accordance with the
laws of the State of California.

        17. SEVERABILITY. Should any provision or portion of this Agreement be
held to be unenforceable or invalid for any reason, the remaining provisions and
portions of this Agreement shall be unaffected by such holding.

        18. COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original and all of which
together shall be deemed one instrument.

        19. SECURITIES LAW COMPLIANCE. The sale of the Shares that are the
subject of this Agreement has not been qualified with the administrator of the
securities laws of any state and the issuance of such Shares or the payment or
receipt of any part of the consideration therefor prior to such qualification
may be unlawful, unless the sale of such Shares is exempt from such
qualification. The rights of all parties to this Agreement are expressly
conditioned upon such qualification being obtained, unless the sale is so
exempt.

        IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first above written.
