OF 1933 ("ACT"), AND THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR

                             STOCK PURCHASE WARRANT
               RIGHT TO PURCHASE _________ SHARES OF COMMON STOCK

THIS CERTIFIES THAT _______________ and all registered and permitted assigns
(collectively, "Holder") is entitled to purchase, on or before March 1, 2000
____________ (_________) shares of the common stock ("Common Stock") of
AMERICAN TECHNOLOGY CORPORATION (the "Corporation" or "Company") upon exercise
of this Warrant along with presentation of the full purchase price. The
purchase price of the common stock upon exercise of this Warrant ("Warrant
Shares") is equal to the Five Dollars ($5.00) per share (the "Exercise Price").
This Warrant is granted to Holder for valuable consideration received.

1.       Exercise of Warrant. This Warrant may be exercised in whole or in part
on any business day on or before the expiration date listed above by
presentation and surrender hereof to the Company at its principal office of an
exercise request and the Exercise Price in lawful money of the United States of
America in the form of a wire transfer or check, subject to collection, for the
number of Warrant Shares specified in the exercise request. If this Warrant
should be exercised in part only, the Company shall, upon surrender of this
Warrant, execute and deliver a new Warrant evidencing the rights of the Holder
thereof to purchase the balance of the Warrant Shares purchasable hereunder.
Upon receipt by the Company of this Warrant and an exercise request and
representations, together with proper payment of the Exercise Price, at such
office, the Holder shall be deemed to be the holder of record of the Warrant
Shares, notwithstanding that the stock transfer books of the Company shall then
be closed or that certificates representing such Warrant Shares shall not then
be actually delivered to the Holder. The Company shall pay any and all transfer
agent fees, documentary stamp or similar issue or transfer taxes payable in
respect of the issue or delivery of the Warrant Shares.

2.       Adjustment of Exercise Price and Number of Shares Deliverable Upon
Exercise of Warrant. The Exercise Price and the number of Shares purchasable
upon the exercise of this Warrant are subject to adjustment from time to time
upon the occurrence of the events enumerated in this paragraph.

(a)      In case the Corporation shall at any time after the date of this
         Warrant:

         (i) Pay a dividend of its shares of its Common Stock or make a
         distribution in shares of its Common Stock with respect to its
         outstanding Common Stock;

         (ii) Subdivide its outstanding shares of Common Stock;

         (iii) Combine its outstanding shares of Common Stock; or

         (iv) Issue any other shares of capital stock by reclassification of
         its shares of Common Stock;

the Exercise Price in effect at the time of the record date of such dividend,
subdivision, combination, or reclassification shall be proportionately adjusted
so that Holder shall be entitled to receive the aggregate number and kind of
shares which, if this Warrant had been exercised prior to such event, Holder
would have owned upon such exercise and been entitled to receive by virtue of
such dividend, subdivision, combination, or reclassification. Such adjustment
shall be made successively whenever any event listed above shall occur.

(b)      In case of any reorganization of the Corporation, or in case of any
reclassification or change of outstanding Common Stock issuable upon exercise
of this Warrant (other than a change in par value, or from par value to no par
value, or from no par value to par value, or as a result of a subdivision or
split-up or combination of the Common Stock), or in case of any consolidation
or merger of the Company with or into another entity (other than a
consolidation or merger with a subsidiary or a continuing corporation), or in
case of any sale or conveyance to another entity of all or substantially all of
the property of the Corporation, then, as a condition of such reorganization,
reclassification, change, consolidation, merger, sale, or conveyance, the
Corporation or such successor or purchasing entity, as the case may be, shall
forthwith provide to Holder a supplemental warrant (the "Supplemental Warrant")
which will make lawful and




                                       9
   3
adequate provision whereby Holder shall have the right thereafter to receive,
upon exercise of such Supplemental Warrant, the kind and amount of shares and
other securities and property which would have been received upon such
reorganization, reclassification, change, consolidation, merger, sale, or
conveyance by a holder of a number of shares of Common Stock equal to the
number of Shares issuable upon exercise of this Warrant immediately prior to
such reorganization, reclassification, change, consolidation, merger, sale, or
conveyance. Such Supplemental Warrant shall include provisions for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this paragraph. The above provisions of this paragraph shall
similarly apply to successive reorganizations, reclassifications, and changes
of Common Stock and to successive consolidations, mergers, sales, or
conveyances.

3. Representations

Holder has been advised and understands that the Warrants and the Shares
purchasable thereby are characterized as "restricted securities" under the
federal securities laws because they are being acquired from Company in a
transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under
the Act only in certain limited circumstances.Holder further understands that
the certificates evidencing the Shares will bear the following legend: "These
securities have not been registered under the Securities Act of 1933. They may
not be sold, offered for sale, pledged or hypothecated in the absence of a
registration statement in effect with respect to the securities under such Act
or an opinion of counsel satisfactory to the Company that such registration is
not required or unless sold pursuant to Rule 144 of such Act."

The Holder understands that the Company may place, and may instruct any
transfer agent or depository for the Shares to place, a stop transfer notation
in the securities records in respect of the Shares.

4.       Registration Rights

As promptly as practicable following the completion or termination of the
offering of promissory notes of which this Warrant is a part, the Company has
agreed within 60 days of such completion ("Filing Date") to prepare and cause a
registration statement on Form S-3, Form SB-2 or other appropriate form to be
filed with the Securities and Exchange Commission for the purpose of
registering under the Act the shares for issuance to noteholders upon
conversion of the promissory notes.

If the shares underlying this Warrant can be registered within the same
registration statement selected by the Company, then the Company shall include
such Warrant Shares. Otherwise such Warrant Shares shall have a one-time
piggyback registration right in a future registrations other than a
registration relating solely to employee benefit plans.

If the Warrant holder fails to exercise this warrant and obtain the Warrant
Shares after the effective date of such one time registration statement and
during the period the registration statement remains current, the Company shall
have no obligation to amend any such registration statement or file any further
registration statements concerning such Warrant Shares.

5.       Assignment or Loss of Warrant.

(a) The Holder of this Warrant, without obtaining the prior written consent of
the Company, shall not transfer or assign its interest in this Warrant, or any
of the Warrant Shares prior to exercise, in whole or in part to any transferee.

(b) Upon receipt of evidence satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant, and (in the case of loss, theft or
destruction) of indemnification satisfactory to the Company, and upon surrender
and cancellation of this Warrant, if mutilated, the Company shall execute and
deliver a new Warrant of like tenor and date.

6.       Reservation of Shares. The Company hereby agrees that at all times
there shall be reserved for issuance and delivery upon exercise or exchange of
this Warrant all shares of its Common Stock or other shares of capital stock of
the Company from time to time issuable upon exercise or exchange of this
Warrant. All such shares shall be duly authorized and, when issued upon the
exercise or exchange of the Warrant in accordance with the terms hereof, shall
be validly issued, fully paid and nonassessable, free and clear of all liens,
security interests, charges and other encumbrances or restrictions on sale
(other than as provided in the Company's articles of incorporation and any
restrictions on sale set forth herein or pursuant to applicable federal and
state securities laws) and free and clear of all preemptive rights.

7.       Arbitration. In the event that a dispute arises between the
Corporation and the holder of this Warrant as to any matter relating to this
Warrant, the matter shall be settled by arbitration in San Diego, California in
accordance with the Rules

proceedings shall be brought in no other forum or venue.

its duly authorized officers effective on this 25th day of March 1997.
