                              CUSIP ______________

                  THIS CERTIFIES THAT



or registered assigns, is the registered holder of the number of Warrants (the
"Warrants") set forth above. Each Warrant entitles the holder thereof to
purchase from TASER International, Inc., a corporation incorporated under the
laws of the state of Delaware (the "Company"), subject to the terms and
conditions set forth hereinafter and in the Warrant Agreement hereinafter more
fully described (the "Warrant Agreement"), at any time on or before the close of
business on __________, 2006 or, if such Warrant is redeemed as provided in the
Warrant Agreement, at any time prior to the effective time of such redemption
(the "Expiration Date"), one fully paid and non-assessable share of Common Stock
of the Company (the "Common Stock") upon presentation and surrender of this
Warrant Certificate, with the instructions for the registration and delivery of
Common Stock filled in, at the stock transfer office in Glendale, California, of
U.S. Stock Transfer Corporation, Warrant Agent of the Company (the "Warrant
Agent") or of its successor warrant agent or, if there be no successor warrant
agent, at the corporate offices of the Company, and upon payment of the Exercise
Price (as defined in the Warrant Agreement) and any applicable taxes paid either
in cash, or by certified or official bank check, payable in lawful money of the
United States of America to the order of the Company. Each Warrant initially
entitles the holder to purchase one share of Common Stock initially for $ [150%
of the initial public offering price of the Units]. The number and kind of
securities or other property for which the Warrants are exercisable are subject
to further adjustment in certain events, such as mergers, splits, stock
dividends, recapitalizations and the like, to prevent dilution. After three
months following the closing of the Company's initial public offering, the
Company may redeem any or all outstanding and unexercised Warrants at any time
if the average Daily Price equals or exceeds $_____ [200% of the initial public
offering price of the Units] for ten consecutive trading days immediately
preceding the date of notice of such redemption, upon 30 days notice, at a price
equal to $0.25 per Warrant. For the purpose of the foregoing sentence, the term
"Daily Price" shall mean, for any relevant day, the closing bid price on that
day as reported by the principal exchange or quotation system on which prices
for the Common Stock are reported. All Warrants not theretofore exercised or
redeemed will expire on _________, 2006.

                  This Warrant Certificate is subject to all of the terms,
provisions and conditions of the Warrant Agreement, dated as of ____________,
2001 (the "Warrant Agreement"), between
<PAGE>   2
the Company and the Warrant Agent, to all of which terms, provisions and
conditions the registered holder of this Warrant Certificate consents by
acceptance hereof. The Warrant Agreement is incorporated herein by reference and
made a part hereof and reference is made to the Warrant Agreement for a full
description of the rights, limitations of rights, obligations, duties and
immunities of the Warrant Agent, the Company and the holders of the Warrant
Certificates. Copies of the Warrant Agreement are available for inspection at
the stock transfer office of the Warrant Agent or may be obtained upon written
request addressed to the Company at 7860 East McClain Drive, Suite 2,
Scottsdale, Arizona 85260, Attention: Chief Financial Officer.

                  The Company shall not be required upon the exercise of the
Warrants evidenced by this Warrant Certificate to issue fractions of Warrants,
Common Stock or other securities, but shall make adjustment therefor in cash on
the basis of the current market value of any fractional interest as provided in
the Warrant Agreement.

                  In certain cases, the sale of securities by the Company upon
exercise of Warrants would violate the securities laws of the United States,
certain states thereof or other jurisdictions. The Company has agreed to use all
commercially reasonable efforts to cause a registration statement to continue to
be effective during the term of the Warrants with respect to such sales under
the Securities Act of 1933, as amended, and to take such action under the laws
of various states as may be required to cause the sale of securities upon
exercise to be lawful. However, the Company will not be required to honor the
exercise of Warrants if, in the opinion of the Board of Directors, upon advice
of counsel, the sale of securities upon such exercise would be unlawful. In
certain cases, the Company may, but is not required to, purchase Warrants
submitted for exercise for a cash price equal to the difference between the
market price of the securities obtainable upon such exercise and the exercise
price of such Warrants.

                  This Warrant Certificate, with or without other Warrant
Certificates, upon surrender to the Warrant Agent, any successor warrant agent
or, in the absence of any successor warrant agent, at the corporate offices of
the Company, may be exchanged for another Warrant Certificate or Certificates
evidencing in the aggregate the same number of Warrants as the Warrant
Certificate or Certificates so surrendered. If the Warrants evidenced by this
Warrant Certificate shall be exercised in part, the holder hereof shall be
entitled to receive upon surrender hereof another Warrant Certificate or
Certificates evidencing the number of Warrants not so exercised.

                  No holder of this Warrant Certificate, as such, shall be
entitled to vote, receive dividends or be deemed the holder of Common Stock or
any other securities of the Company which may at any time be issuable on the
exercise hereof for any purpose whatever, nor shall anything contained in the
Warrant Agreement or herein be construed to confer upon the holder of this
Warrant Certificate, as such, any of the rights of a stockholder of the Company
or any right to vote for the election of directors or upon any matter submitted
to stockholders at any meeting thereof or give or withhold consent to any
corporate action (whether upon any matter submitted to stockholders at any
meeting thereof, or give or withhold consent to any merger, recapitalization,
issuance of stock, reclassification of stock, change of par value or change of
stock to no par value, consolidation, conveyance or otherwise) or to receive
notice of meetings or

<PAGE>   3
other actions affecting stockholders (except as provided in the Warrant
Agreement) or to receive dividends or subscription rights or otherwise until the
Warrants evidenced by this Warrant Certificate shall have been exercised and the
Common Stock purchasable upon the exercise thereof shall have become deliverable
as provided in the Warrant Agreement.

                  If this Warrant Certificate shall be surrendered for exercise
within any period during which the transfer books for the Company's Common Stock
or other class of stock purchasable upon the exercise of the Warrants evidenced
by this Warrant Certificate are closed for any purpose, the Company shall not be
required to make delivery of certificates for shares purchasable upon such
transfer until the date of the reopening of said transfer books.

                  Every holder of this Warrant Certificate by accepting the same
consents and agrees with the Company, the Warrant Agent, and with every other
holder of a Warrant Certificate that:

                  (a) This Warrant Certificate is transferable on the registry
books of the Warrant Agent only upon the terms and conditions set forth in the
Warrant Agreement; and

                  (b) The Company and the Warrant Agent may deem and treat the
person in whose name this Warrant Certificate is registered as the absolute
owner hereof (notwithstanding any notation of ownership or other writing thereon
made by anyone other than the Company or the Warrant Agent) for all purposes
whatever and neither the Company nor the Warrant Agent shall be affected by any
notice to the contrary.

                  The Company shall not be required to issue or deliver any
certificate for shares of Common Stock or other securities upon the exercise of
Warrants evidenced by this Warrant Certificate until any tax which may be
payable in respect thereof by the holder of this Warrant Certificate pursuant to
the Warrant Agreement shall have been paid, such tax being payable by the holder
of this Warrant Certificate at the time of surrender.

                  This Warrant Certificate shall not be valid or obligatory for
any purpose until it shall have been countersigned by the Warrant Agent.

                  WITNESS the facsimile signatures of the proper officers of the
Company and its corporate seal.
