STOCK OPTION AGREEMENT

      THIS STOCK OPTION AGREEMENT (the "Agreement") is made effective January
15, 2004 between IQ BIOMETRIX, INC., a Delaware corporation (the "Company"), and
Michael Walsh ("Optionee").

                                    RECITALS:

      A. The Company has retained Optionee as its Chief Financial Officer.

      B. In order to provide incentives, the Company has determined to grant to
Optionee the right to acquire certain shares of the Company's common stock with
par value of $0.01 per share (hereinafter called "Common Stock"), all as
provided more fully hereinafter, all subject to the terms, provisions and
conditions of this Agreement.

                                   WITNESSETH:

      1. GRANT OF STOCK OPTION; PURCHASE PRICE; VESTING; EXPIRATION DATE.
Subject to any vesting schedule attached hereto, the Company hereby grants to
Optionee the right to purchase 250,000 shares of Common Stock at a per-share
purchase price of $1.50, pursuant to the terms, provisions and conditions of
this Agreement (the shares of Common Stock pursuant to which Optionee shall
acquire the right to purchase are referred to hereinafter as the "Option
Shares"). If no vesting schedule is attached hereto or if an attached vesting
schedule does not provide for specifics regarding the vesting of the option
granted hereby, the option granted hereby shall become vested and exercisable
with respect to all of Option Shares immediately upon the execution and delivery
of this Agreement by the Company. The option granted hereunder shall expire with
respect to any particular Option Shares Five (5) years after such option becomes
vested with respect to such shares. In the event of Optionee's death prior to
the otherwise applicable expiration date, the option created by this Agreement
(to the extent then vested) shall be exercisable for one year after Optionee's
death by the legal representative of the estate of Optionee or the person(s) who
acquires the rights of Optionee hereunder by bequest or inheritance as a result
of the death of Optionee.

      2. EXERCISE. Subject to the limitations contained herein, Optionee may
exercise the option created pursuant to this Agreement with respect to vested
Option Shares at any time after it becomes effective and such Option Shares
vest. If Optionee or Optionee's successor fails to exercise the option created
under this Agreement with respect to any vested Option Shares on or before the
expiration date provided for herein with respect to such Option Shares, the
option with respect to such vested Option Shares shall expire on such expiration
date and be of no further force and effect. The option to purchase granted
hereunder shall be exercised by giving written notice to the Company in
compliance with this Agreement. Such notice shall state the number of vested
Option Shares with respect to which the option is being exercised and shall
specify a date which shall not be less than fifteen (15) nor more than thirty
(30) days after the date of such notice, as the date on which such Option Shares
will be taken up and payment made therefore in cash, certified or bank cashier's
check, or the equivalent, at the principal office of the Company. If any law or
regulation requires the Company to take any action with respect to the vested
Option Shares specified in such notice, then the date of the delivery of such
Option Shares against payment therefor shall be extended for the period
necessary to take such action. In the event of any failure to take up and pay
for the number of vested Option Shares specified in such notice on the date set
forth therein, as the same may be extended as provided above, such exercise of
this option may be terminated by the Company with respect to such number of
vested Option Shares not taken and paid for. Each exercise of an option pursuant
to this Agreement shall be deemed to be an exercise with respect to the Option
Shares having the earliest expiration date.

      3. ADJUSTMENTS.

      (a) If the outstanding shares of the Common Stock shall be subdivided into
a greater number of shares or a dividend in Common Stock shall be paid in
respect of Common Stock, the per share purchase price of the Option Shares in
effect immediately prior to such subdivision or at the record date of such
dividend shall simultaneously with the effectiveness of such subdivision or
immediately after the record date of such dividend be proportionately reduced.
If the outstanding shares of Common Stock shall be combined into a smaller
number of shares, the per share purchase price of the Option Shares in effect
immediately prior to such combination shall, simultaneously with the
effectiveness of such combination, be proportionately increased. When any
adjustment is required to be made in the per share purchase price of the Option
Shares, the number of Option Shares purchasable upon the exercise of the Option
shall be changed to the number determined by dividing (i) an amount equal to the
number of shares issuable upon the exercise of the Option immediately prior to
such adjustment, multiplied by the per share purchase price of the Option Shares
in effect immediately prior to such adjustment, by (ii) the per share purchase
price of the Option Shares in effect immediately after such adjustment.

      (b) If there shall occur any capital reorganization or reclassification of
the Common Stock (other than a change in par value or a subdivision or
combination as provided for in subsection (a) immediately above), or any
consolidation or merger of the Company with or into another corporation, or a
transfer of all or substantially all of the assets of the Company, or the
payment of a liquidating distribution then, as part of any such reorganization,
reclassification, consolidation, merger, sale or liquidating distribution,
lawful provision shall be made so that Optionee shall have the right thereafter
to receive upon the exercise hereof (to the extent, if any, still exercisable)
the kind and amount of shares of stock or other securities or property which
Optionee would have been entitled to receive if, immediately prior to any such
reorganization, reclassification, consolidation, merger, sale or liquidating
distribution, as the case may be, Optionee had held the number of shares of
Common Stock which were then purchasable upon the exercise of the Option. In any
such case, appropriate adjustment (as reasonably determined by the Board of
Directors of the Company) shall be made in the application of the provisions set
forth herein with respect to the rights and interests thereafter of Optionee
such that the provisions set forth in this Section 3 (including provisions with
respect to adjustment of the per share purchase price of the Option Shares)
shall thereafter be applicable, as nearly as is reasonably practicable, in
relation to any shares of stock or other securities or property thereafter
deliverable upon the exercise of the Option.

      (c) for purposes of this Section, a change in control shall be deemed to
have occurred upon (i) the event of a merger, consolidation, share exchange or
reorganization, unless the stockholders of the Company, immediately before such
merger, consolidation, share exchange or reorganization, own, directly or
indirectly immediately following such merger, consolidation, share exchange or
reorganization, more than fifty percent (50%) of the combined voting power of
the outstanding voting securities of the corporation that is the successor in
such merger, consolidation, share exchange or reorganization in substantially
the same proportion as their ownership of the voting securities immediately
before such merger, consolidation, share exchange or reorganization or (ii) an
agreement for the sale or other disposition of all or substantially all of the
assets of IQB. In the event of a change of control, the Company shall give
notice to the Registered Holder to such effect at least 30 days prior to the
proposed date of the change in control. Notwithstanding anything else contained
herein, in the event of a change in control, 100% of the then unvested shares
shall immediately become vested shares upon the giving of the Company's notice
pursuant to the preceding sentence.

      4. SHARES RESERVED. The Company will, at all times during the term of this
Agreement, reserve and keep available such number of its common shares as will
be sufficient to satisfy the requirements of this Agreement and will pay all
fees and expenses necessarily incurred by the Company in connection with the
issuance of such shares.

      5. RESTRICTION ON ISSUANCE OF SHARES; LEGENDS. The Company will not be
obligated to sell any Option Shares hereunder unless the Option Shares are at
the time exempt from registration under the Securities Act of 1933, as amended,
and applicable state securities laws. Optionee shall make such investment
representations to the Company and shall consent to the imposition of such
legends on the stock certificates as are necessary, in the opinion of the
Company's counsel, to secure to the Company an appropriate exemption from
applicable securities laws.

      6. SUCCESSORS. This Agreement will be binding upon any successor of the
Company.

      7. NO RIGHTS AS SHAREHOLDER. Optionee shall have no rights as a
shareholder by reason of this Agreement and shall have only those rights
expressly conferred by this Agreement.

      8. NONTRANSFERABILITY. This option will not be transferable other than by
will or the laws of descent or distribution or pursuant to a qualified domestic
relations order as defined in the Internal Revenue Code of 1986, as amended, or
Title I of the Employee Retirement Income Security Act of 1974, as amended, or
the rules thereunder, and during the lifetime of Optionee the option may be
exercised only by Optionee. More particularly (but without limiting the
generality of the foregoing), the option may not be assigned, transferred,
pledged or hypothecated in any way, may not be assignable by operation of law,
and may not be subject to execution, attachment or similar process. Any
attempted assignment, transfer, pledge, hypothecation or other disposition of
the option contrary to the provisions hereof, and the levy of any execution,
attachment or similar process upon the option, will be null and void and without
effect.

      9. WITHHOLDING TAXES. Upon exercise of any portion of this option and
notice from the Company to Optionee, Optionee shall pay to the Company the
amount of withholding income tax required to be withheld by the Company from
compensation to Optionee and in turn paid by the Company to the U.S. Internal
Revenue Service.

      10. NOTICES. All notices, requests, demands and other communications
