                               INCENTIVE STOCK OPTION


_______________________, Optionee:

     JAVELIN SYSTEMS, INC. (the "Company"), pursuant to its 1997 Equity
Incentive Plan (the "Plan"), has granted to you, the optionee named above, an
option to purchase shares of the common stock of the Company ("Common Stock"). 
This option is intended to qualify as an "incentive stock option" within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code").

     The grant hereunder is in connection with and in furtherance of the
Company's compensatory benefit plan for participation of the Company's employees
(including officers), directors or consultants.  Defined terms not explicitly
defined in this agreement but defined in the Plan shall have the same
definitions as in the Plan.

     The details of your option are as follows:

     1.   TOTAL NUMBER OF SHARES SUBJECT TO THIS OPTION.  The total number of
shares of Common Stock subject to this option is ____________________
(__________).

     2.   VESTING.  Subject to the limitations contained herein, __________
[INDICATE A FRACTION OR PERCENTAGE (E.G., 25% OR 12/48THS)] of the shares will
vest (become exercisable) on ____________, 19__ and __________ of the shares
will then vest each ____________ [INDICATE APPLICABLE TIME PERIOD (E.G., MONTH
OR YEAR)] thereafter until either (i) you cease to provide services to the
Company for any reason, or (ii) this option becomes fully vested.

     3.   EXERCISE PRICE AND METHOD OF PAYMENT.

          (a)  EXERCISE PRICE.  The exercise price of this option is
___________________________ ($___________) per share, being not less than the
fair market value of the Common Stock on the date of grant of this option.

          (b)  METHOD OF PAYMENT.  Payment of the exercise price per share is
due in full upon exercise of all or any part of each installment which has
accrued to you.  You may elect, to the extent permitted by applicable statutes
and regulations, to make payment of the exercise price under one of the
following alternatives:

                                     1.
<PAGE>

               (i)  Payment of the exercise price per share in cash (including
check) at the time of exercise;

               (ii) Payment pursuant to a program developed under Regulation T
as promulgated by the Federal Reserve Board which, prior to the issuance of
Common Stock, results in either the receipt of cash (or check) by the Company or
the receipt of irrevocable instructions to pay the aggregate exercise price to
the Company from the sales proceeds;

               (iii)     Provided that at the time of exercise the Company's
Common Stock is publicly traded and quoted regularly in the Wall Street Journal,
payment by delivery of already-owned shares of Common Stock, held for the period
required to avoid a charge to the Company's reported earnings, and owned free
and clear of any liens, claims, encumbrances or security interests, which Common
Stock shall be valued at its fair market value on the date of exercise; or

               (iv) Payment by a combination of the methods of payment permitted
by subparagraph 3(b)(i) through 3(b)(iii) above.

     4.   WHOLE SHARES.  This option may not be exercised for any number of
shares which would require the issuance of anything other than whole shares.  

     5.   SECURITIES LAW COMPLIANCE.  Notwithstanding anything to the contrary
contained herein, this option may not be exercised unless the shares issuable
upon exercise of this option are then registered under the Act or, if such
shares are not then so registered, the Company has determined that such exercise
and issuance would be exempt from the registration requirements of the Act.

     6.   TERM.  The term of this option commences on __________, 19__, the date
of grant, and expires on ________________________ (the "Expiration Date," which
date shall be no more than ten (10) years from the date this option is granted),
unless this option expires sooner as set forth below or in the Plan.  In no
event may this option be exercised on or after the Expiration Date.  This option
shall terminate prior to the Expiration Date as follows:  THREE (3) MONTHS after
the termination of your Continuous Status as an Employee, Director or Consultant
with the Company or an Affiliate of the Company unless one of the following
circumstances exists:  

          (a)  Your termination of Continuous Status as an Employee, Director or
Consultant is due to your disability.  This option will then expire on the
earlier of the Expiration Date set forth above or twelve (12) months following
such termination of Continuous Status as an Employee, Director or Consultant. 
You should be aware that if your disability is not considered a permanent and
total disability within the meaning of Section 422(c)(6) of the Code, and you
exercise this option more than three (3) months 

                                     2.
<PAGE>

following the date of your termination of employment, your exercise will be 
treated for tax purposes as the exercise of a "nonstatutory stock option" 
instead of an "incentive stock option."

          (b)  Your termination of Continuous Status as an Employee, Director or
Consultant is due to your death or your death occurs within THREE (3) MONTHS
following your termination of Continuous Status as an Employee, Director or
Consultant for any other reason.  This option will then expire on the earlier of
the Expiration Date set forth above or eighteen (18) months after your death.

          (c)  If during any part of such THREE (3) MONTH period you may not
exercise your option solely because of the condition set forth in paragraph 5
above, then your option will not expire until the earlier of the Expiration Date
set forth above or until this option shall have been exercisable for an
aggregate period of THREE (3) MONTHS after your termination of Continuous Status
as an Employee, Director or Consultant. 

          (d)  If your exercise of the option within THREE (3) MONTHS after
termination of your Continuous Status as an Employee, Director or Consultant
with the Company or with an Affiliate of the Company would result in liability
under section 16(b) of the Securities Exchange Act of 1934, then your option
will expire on the earlier of (i) the expiration date set forth above, (ii) the
tenth (10th) day after the last date upon which exercise would result in such
liability or (iii) six (6) months and ten (10) days after the termination of
your Continuous Status as an Employee, Director or Consultant with the Company
or an Affiliate of the Company.  

     However, this option may be exercised following termination of Continuous
Status as an Employee, Director or Consultant only as to that number of shares
as to which it was exercisable on the date of termination of Continuous Status
as an Employee, Director or Consultant under the provisions of paragraph 2 of
this option.

     In order to obtain the federal income tax advantages associated with an
"incentive stock option," the Code requires that at all times beginning on the
date of grant of the option and ending on the day three (3) months before the
date of the option's exercise, you must be an employee of the Company or an
Affiliate of the Company, except in the event of your death or permanent and
total disability.  The Company has provided for continued vesting or extended
exercisability of your option under certain circumstances for your benefit, but
cannot guarantee that your option will necessarily be treated as an "incentive
stock option" if you provide services to the Company or an Affiliate of the
Company as a consultant or exercise your option more than three (3) months after
the date your employment with the Company and all Affiliates of the Company
terminates.

     7.   EXERCISE.

          (a)       This option may be exercised, to the extent specified above,
by delivering a notice of exercise (in a form designated by the Company)
together with the exercise price to the Secretary of the Company, or to such
other person as the Company may designate, during regular business hours,
together with such additional documents as the Company may then require.

          (b)  By exercising this option you agree that:

               (i)  as a precondition to the completion of any exercise of this
option, the Company may require you to enter an arrangement providing for the
payment by you to the Company of any tax withholding obligation of the Company
arising by reason of (1) the exercise of this option; (2) the lapse of any
substantial risk of forfeiture to which the shares are subject at the time of
exercise; or (3) the disposition of shares acquired upon such exercise; and 

               (ii) you will notify the Company in writing within fifteen (15)
days after the date of any disposition of any of the shares of the Common Stock
issued upon exercise of this option that occurs within two (2) years after the
date of this option grant or within one (1) year after such shares of Common
Stock are transferred upon exercise of this option.

     8.   TRANSFERABILITY.  This option shall not be transferable except by will
or by the laws of descent and distribution, and shall be exercisable during the
lifetime of the person to whom the Option is granted only by such person and
such person's guardian or legal representative; provided, however, that the
Board may, in its discretion, waive such restriction in any case when such
restriction is no longer required by applicable law.

     9.   OPTION NOT A SERVICE CONTRACT.  This option is not an employment
contract and nothing in this option shall be deemed to create in any way
whatsoever any obligation on your part to continue in the employ of the Company,
or of the Company to continue your employment with the Company.  In addition,
nothing in this option shall obligate the Company or any Affiliate of the
Company, or their respective shareholders, Board of Directors, officers or
employees to continue any relationship which you might have as a Director or
Consultant for the Company or Affiliate of the Company.  

     10.  NOTICES.  Any notices provided for in this option or the Plan shall be
given in writing and shall be deemed effectively given upon receipt or, in the
case of notices delivered by the Company to you, five (5) days after deposit in
the United States mail, postage prepaid, addressed to you at the address
specified below or at such other address as you hereafter designate by written
notice to the Company.

                                     4.
