                               EP MEDSYSTEMS, INC.

           WARRANT FOR THE PURCHASE OF 100,000 SHARES OF COMMON STOCK

Warrant No. EP2001A-1                      This Warrant Expires on July 20, 2006

      This is to certify that, FOR VALUE RECEIVED, REINHARD SCHMIDT (the
"Holder"), is entitled to purchase, subject to the provisions of this Warrant,
from EP MEDSYSTEMS, INC., a New Jersey corporation (the "Company"), 100,000
fully paid, validly issued and nonassessable shares of common stock, no par
value, $.001 stated value per share, of the Company (the "Common Stock") at an
exercise price of $2.75 per share upon the terms and conditions set forth
herein, at any time or from time to time before 5:00 P.M. on July 20, 2006,
Eastern Standard Time (the "Exercise Period").

      The number of shares of Common Stock to be received upon the exercise of
this Warrant and the price to be paid for each share of Common Stock may be
adjusted from time to time as hereinafter set forth. The shares of Common Stock
deliverable upon such exercise, and as adjusted from time to time, are
hereinafter sometimes referred to as "Warrant Shares" and the exercise price of
a share of Common Stock in effect at any time and as adjusted from time to time
is hereinafter sometimes referred to as the "Exercise Price".

      1. EXERCISE OF WARRANT. This Warrant may be exercised in whole or in part,
during the Exercise Period by the presentation and surrender of this Warrant to
the Company at 100 Stierli Court, Suite 107, Mount Arlington, New Jersey 07856,
Attention: Chief Executive Officer, or at such other place as is designated in
writing by the Company, with the purchase form annexed hereto duly executed and
accompanied by payment of the Exercise Price for the number of Warrant Shares
specified in such form. The Exercise Price may be paid by bank check or wire
transfer. As soon as practicable after each such exercise of this Warrant, but
not later than seven (7) days from the date of such exercise, the Company shall
issue and deliver to


                                      E-20
<PAGE>

the Holder a certificate for the Warrant Shares issuable upon such exercise,
registered in the name of the Holder. If this Warrant should be exercised in
part only, the Company shall, upon surrender of this Warrant for cancellation,
execute and deliver a new Warrant evidencing the rights of the Holder thereof to
purchase the balance of the Warrant Shares purchasable thereunder. Upon receipt
by the Company of this Warrant at its office, in proper form for exercise, the
Holder shall be deemed to be the holder of record of the shares of Common Stock
issuable upon such exercise, notwithstanding that the stock transfer books of
the Company shall then be closed or that certificates representing such shares
of Common Stock shall not then be physically delivered to the Holder.

      2. RESERVATION OF SHARES. The Company shall at all times reserve for
issuance and/or delivery upon exercise of this Warrant such number of shares of
its Common Stock as shall be required for issuance and delivery upon exercise of
this Warrant.

      3. FRACTIONAL SHARES. No fractional shares of Common Stock shall be issued
upon the exercise of this Warrant. With respect to any fraction of a share
called for upon any exercise hereof, the Company shall pay to the Holder an
amount in cash equal to such fraction multiplied by the Current Weighted Market
Price of one share of Common Stock.

      4. ANTIDILUTION PROVISIONS. In the event the Common Stock is changed by
reason of a stock split, reverse stock split, stock dividend or recapitalization
or is converted into or exchanged for other securities as a result of a merger,
consolidation or reorganization in which the Company is the surviving
corporation, appropriate adjustments shall be made in the terms of this Warrant,
or additional warrants shall be granted to the Holder as shall be equitable and
appropriate, or an adjustment in the number and class of shares allocated to,
and the Exercise Price of, this Warrant shall likewise be made.

      5. CERTAIN EXTRAORDINARY TRANSACTIONS. In the event the Common Stock is
exchanged for securities, cash or other property of any other corporation or
entity as the result of a reorganization, merger or consolidation in which the
Company is not the surviving corporation, the dissolution or liquidation of the
Company, or the sale of all or substantially all the assets of the Company, the
Board of Directors of the Company or the board of directors of any successor
corporation or entity may, in its discretion, as to the unexercised portion of
this Warrant, (a) provide for payment of an amount equal to the excess of the
fair market value of the Warrant Shares, as determined by the Board of Directors
of the Company or such board, over the Exercise Price of such Warrant Shares as
of the date of the transaction, in exchange for the surrender of the right to
exercise this Warrant, or (b) provide for the assumption of this Warrant, or the
substitution therefor of new warrants, by the successor corporation or entity.

      6. LOSS OF WARRANT. Upon receipt by the Company of evidence satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant, and (in the
case of loss, theft or destruction) of reasonably satisfactory indemnification,
and upon surrender and cancellation of this Warrant, if mutilated, the Company
will execute and deliver a new warrant of like tenor and date.

      7. NO RIGHTS AS SHAREHOLDER. The Holder shall not, as holder of this
Warrant, be entitled to vote, if applicable, or to receive dividends or to be
deemed the holder of


                                      E-21
<PAGE>

Common Stock that may at any time be issuable upon exercise of this Warrant for
any purpose whatsoever, nor shall anything contained herein be construed to
confer upon the Holder, as such, any of the rights of a shareholder of the
Company or, if applicable, any right to vote for the election of directors or
upon any matter submitted to shareholders at any meeting thereof, or to give or
withhold consent to any corporate action (whether upon any recapitalization,
issue or reclassification of stock, change of par value or change of stock to no
par value, consolidation, merger or conveyance or otherwise), or to receive
notice of meetings, or to receive dividends or subscription rights, until such
holder shall have exercised the Warrant and been issued the Warrant Shares in
accordance with the provisions hereof.

      8. NON-TRANSFERABILITY. Neither this Warrant nor any Warrant Shares shall
be registered under the Securities Act of 1933, as amended, and applicable state
securities laws. Therefore, the Company shall require, as a condition of
allowing the transfer or exchange of this Warrant or such Warrant Shares, that
the Holder of this Warrant or such Warrant Shares, as the case may be, furnish
to the Company an opinion of counsel reasonably acceptable to the Company to the
effect that such transfer or exchange will be exempt from the registration and
prospectus delivery requirements under the Securities Act of 1933, as amended,
and applicable state securities laws. The certificates evidencing the Warrant
Shares shall bear a legend to the effect that the Warrant Shares evidenced by
such certificate have not been registered under the Securities Act of 1933, as
amended, and applicable state securities laws and are, therefore, subject to
restrictions on transfer.

      9. INVESTMENT REPRESENTATIONS AND WARRANTIES. The Holder hereby represents
and warrants to the Company that (a) he has knowledge and experience in
financial and business matters sufficient to enable him to evaluate the merits
and risks of an investment in the Company; (b) he has assets sufficient to
enable him to bear the economic risk of its investment in this Warrant and the
Warrant Shares and is an "accredited investor" as defined in Rule 501 under the
Securities Act of 1933, as amended; (c) he is acquiring this Warrant and, upon
exercise, will acquire the Warrant Shares, for his own account, and not with a
view to, or for sale in connection with, any distribution thereof; (d) he or his
representatives have received from the Company such information with respect to
the Company as he has deemed necessary and relevant in connection with this
Warrant and the Warrant Shares and he has had the opportunity, directly or
through such representatives, to ask questions of and receive answers from
persons acting on behalf of the Company necessary to verify the information so
obtained; and (e) he has not employed any broker or finder or incurred any
liability for any brokerage or finder's fees or commissions or similar payments
in connection with this Warrant and the Warrant Shares.

      10. GOVERNING LAW. This Agreement and all amendments, modifications,
alterations, or supplements hereto shall be construed under and governed by the
laws of the State of New Jersey and the United States of America, without regard
to the principles of conflicts of law thereof.

      11. MISCELLANEOUS. Except as provided in Sections 4 and 5 hereof, this
Warrant and any term hereof may be changed, waived, discharged or terminated
only by an instrument in writing signed by the party against which enforcement
of such change, waiver, discharge or termination is sought. The headings in this
Warrant are for purposes of reference only and shall


                                      E-22
<PAGE>

not limit or otherwise affect any of the terms hereof. The invalidity or
unenforceability of any provision hereof shall in no way affect the validity or
enforceability of any other provision.

      12. EXPIRATION. The right to exercise this Warrant shall expire at 5:00
P.M. Eastern Standard Time on July 20, 2006.

      This Warrant is executed as of the date and year first written above.
