            8.1 Compliance with Securities Act. The Common Shares shall not be
transferable, except upon the conditions specified in this Section 8, which
conditions are intended to insure compliance with the provisions of the
Securities Act and applicable state securities laws in respect of any such
transfer.

            8.2 Restrictive Legend. Each certificate representing the Common
Shares and any shares of Common Stock or other securities issued upon any stock
split, stock dividend, recapitalization, merger, consolidation, similar event,
shall (unless otherwise permitted by the provisions of Section 8.4 below) be
stamped or otherwise imprinted with the following legend:

      "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE
      SECURITIES LAW AND THE TRANSFERABILITY HEREOF


                                       12
<PAGE>

      IS SUBJECT TO THE PROVISIONS OF A COMMON STOCK AND WARRANT PURCHASE
      AGREEMENT BY AND AMONG EP MEDSYSTEMS, INC. AND THE PURCHASERS LISTED ON

            8.3 Restrictions on Transferability. Until the Common Shares are
registered under the Securities Act, the Company shall not be required to
register the transfer of the Common Shares on the books of the Company unless
the Company shall have been provided with an opinion of counsel reasonably
satisfactory to it prior to such transfer to the effect that registration under
the Securities Act or any applicable state securities law is not required in
connection with the transaction resulting in such transfer. Each certificate for
Common Shares issued upon any transfer as above provided shall bear the
restrictive legend set forth in Section 8.2 above, except that such restrictive
legend shall not be required if the opinion of counsel reasonably satisfactory
to the Company referred to above is to the further effect that such legend is
not required in order to establish compliance with the provisions of the
Securities Act and any applicable state securities law.

            8.4 Termination of Restrictions on Transferability. The conditions
precedent imposed by this Section 8 upon the transferability of the Common
Shares shall cease and terminate as to any of the Common Shares when (i) such
securities shall have been registered under the Securities Act and sold or
otherwise disposed of in accordance with the intended method of disposition by
the seller or sellers thereof set forth in the registration statement covering
such securities, or (ii) at such time as an opinion of counsel satisfactory to
the Company shall have been rendered as required pursuant to the second sentence
of Section 8.3 to the effect that the restrictive legend on such securities is
no longer required, or (iii) when such securities are transferable in accordance
with the provisions of Rule 144 (k) promulgated under the Securities Act and
Section 8.3 above. Whenever the conditions imposed by this Section 8 shall
terminate as hereinabove provided with respect to any of the Common Shares, the
holder of any such securities bearing the legend set forth in this Section 8 as
to which such conditions shall have terminated shall be entitled to receive from
the Company, without expense (except for the payment of any applicable transfer
tax) new stock certificates not bearing such legend.

      SECTION 9. SURVIVAL OF REPRESENTATIONS AND WARRANTIES
