writing its continuing obligation to afford to such holder any rights to which
such holder shall continue to be entitled after such exercise in accordance with
the provisions of this Warrant. If the holder shall fail to make any such
request, such failure shall not affect the continuing obligation of the Company
to afford to such holder any such rights.

          1.6. Trustee for Warrant Holders. In the event that a bank or trust
company shall have been appointed as trustee for the holders of the Warrants
pursuant to Subsection 3.2, such bank or trust company shall have all the powers
and duties of a warrant agent appointed pursuant to Section 11 and shall accept,
in its own name for the account of the Company or such successor person as may
be entitled thereto, all amounts otherwise payable to the Company or such
successor, as the case may be, on exercise of this Warrant pursuant to this
Section 1.

     2.1. Delivery of Stock Certificates, etc. on Exercise. The Company agrees
that the shares of Common Stock purchased upon exercise of this Warrant shall be
deemed to be issued to the holder hereof as the record owner of such shares as
of the close of business on the date on which this Warrant shall have been
surrendered and payment made for such shares as aforesaid. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within 15 days thereafter, the Company at its expense (including the
payment by it of any applicable issue taxes) will cause to be issued in the name
of and delivered to the holder hereof, or as such holder (upon payment by such
holder of any applicable transfer taxes) may direct in compliance with
applicable Securities Laws, a certificate or certificates for the number of duly
and validly issued, fully paid and nonassessable shares of Common Stock (or
Other Securities) to which such holder shall be entitled on such exercise, plus,
in lieu of any fractional share to which such holder would otherwise be
entitled, cash equal to such fraction multiplied by the then Fair Market Value

property (including cash, where applicable) to which such holder is entitled
upon such exercise pursuant to Section 1 or otherwise.

     2.2. Cashless Exercise.

bank check or checks payable to the order of the Company equal to the applicable
aggregate Purchase Price, (ii) by delivery of Warrants, Common Stock and/or
Common Stock receivable upon exercise of the Warrants in accordance with Section
(b) below, or (iii) by a combination of any of the foregoing methods) for the
number of Common Shares specified in such form (as such exercise number shall be
adjusted to reflect any adjustment in the total number of shares of Common Stock
issuable to the holder per the terms of this Warrant) and the holder shall
thereupon be entitled to receive the number of duly authorized, validly issued,
fully-paid and non-assessable shares of Common Stock (or Other Securities)
determined as provided herein.

                                       16
<PAGE>


          (b) Notwithstanding any provisions herein to the contrary, if the Fair
Market Value of one share of Common Stock is greater than the Purchase Price (at
the date of calculation as set forth below), in lieu of exercising this Warrant
for cash the holder may elect to receive shares equal to the value (as
determined below) of this Warrant (or the portion thereof being cancelled) by
surrender of this Warrant at the principal office of the Company together with
the properly endorsed Subscription Form in which event the Company shall issue
to the holder a number of shares of Common Stock computed using the following
formula:

                           X=Y (A-B)
                            A
                        -----

          Where X=  the number of shares of Common Stock to be issued to the
                    holder

                Y=  the number of shares of Common Stock purchasable under the
                    Warrant or, if only a portion of the Warrant is being
                    exercised, the portion of the Warrant being exercised (at
                    the date of such calculation)

                A=  the Fair Market Value of one share of the Company's Common
                    Stock (at the date of such calculation)

                B=  Purchase Price (as adjusted to the date of such calculation)

          (c) Payment of the Purchase Price may be made by the method described
in Section 2.2(a)(ii) of this Warrant only commencing one year after the Issue
Date of this Warrant and then provided either (i) a Non-Registration Event (as
described in Section 9 of this Warrant) has occurred and/or (ii) the Common
Stock issuable upon exercise of this Warrant as of the date of exercise of this
Warrant is not then registered for public resale in a registration statement
declared effective by the Securities and Exchange Commission.

          (d) The maximum number of Common Shares issuable upon cashless
exercise shall not exceed the number of Common Shares issuable upon exercise
requiring the payment of cash by the holder to the Company.

     3.   Adjustment for Reorganization, Consolidation, Merger, etc.

          3.1. Reorganization, Consolidation, Merger, etc. In case at any time
or from time to time, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person, or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition to the consummation of such a transaction, proper and
adequate provision shall be made by the Company whereby the holder of this
Warrant, on the exercise hereof as provided in Section 1 at any time after the
consummation of such reorganization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including cash) to which such holder would have been entitled upon such
consummation or in connection with such dissolution, as the case may be, if such
holder had so exercised this Warrant, immediately prior thereto, all subject to
further adjustment thereafter as provided in Section 4.

                                       17
<PAGE>


          3.2. Dissolution. In the event of any dissolution of the Company
following the transfer of all or substantially all of its properties or assets,
the Company, prior to such dissolution, shall at its expense deliver or cause to
be delivered the stock and other securities and property (including cash, where
applicable) receivable by the holders of the Warrants after the effective date
of such dissolution pursuant to this Section 3 to a bank or trust company having
its principal office in New York, NY, as trustee for the holder or holders of
the Warrants.

          3.3. Continuation of Terms. Upon any reorganization, consolidation,
merger or transfer (and any dissolution following any transfer) referred to in
this Section 3.3, this Warrant shall continue in full force and effect and the
terms hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer, the person acquiring all or substantially all of the
properties or assets of the Company, whether or not such person shall have
expressly assumed the terms of this Warrant as provided in Section 4. In the
event this Warrant does not continue in full force and effect after the
consummation of the transaction described in this Section 3.3, then only in such
event will the Company's securities and property (including cash, where
applicable) receivable by the holders of the Warrants be delivered to the
Trustee as contemplated by Section 3.2.

     4. Extraordinary Events Regarding Common Stock. In the event that the
Company shall (a) issue additional shares of the Common Stock as a dividend or
other distribution on outstanding Common Stock, (b) subdivide its outstanding
shares of Common Stock, or (c) combine its outstanding shares of the Common
Stock into a smaller number of shares of the Common Stock, then, in each such
event, the Purchase Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Purchase Price by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Purchase Price then in effect. The
Purchase Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this Section 4.
The number of shares of Common Stock that the holder of this Warrant shall
thereafter, on the exercise hereof as provided in Section 1, be entitled to
receive shall be adjusted to a number determined by multiplying the number of
shares of Common Stock that would otherwise (but for the provisions of this
Section 4) be issuable on such exercise by a fraction of which (a) the numerator
is the Purchase Price that would otherwise (but for the provisions of this
Section 4) be in effect, and (b) the denominator is the Purchase Price in effect
on the date of such exercise.

     5. Certificate as to Adjustments. In each case of any adjustment or
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of the Warrants, the Company at its expense will promptly cause its
Chief Financial Officer or other appropriate designee to compute such adjustment
or readjustment in accordance with the terms of the Warrant and prepare a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based, including a
statement of (a) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
to have been issued or sold, (b) the number of shares of Common Stock (or Other
Securities) outstanding or deemed to be outstanding, and (c) the Purchase Price
and the number of shares of Common Stock to be received upon exercise of this
Warrant, in effect immediately prior to such adjustment or readjustment and as
adjusted or readjusted as provided in this Warrant. The Company will forthwith
mail a copy of each such certificate to the holder of the Warrant and any
Warrant agent of the Company (appointed pursuant to Section 11 hereof).

                                       18

     6. Reservation of Stock, etc. Issuable on Exercise of Warrant; Financial
Statements. The Company will at all times reserve and keep available, solely for
issuance and delivery on the exercise of the Warrants, all shares of Common
Stock (or Other Securities) from time to time issuable on the exercise of the
Warrant. This Warrant entitles the holder hereof to receive copies of all
financial and other information distributed or required to be distributed to the
holders of the Company's Common Stock.

     7. Assignment; Exchange of Warrant. Subject to compliance with applicable
Securities laws, this Warrant, and the rights evidenced hereby, may be
transferred in amounts of 50,000 Common Shares or more (subject to anti-dilution
and adjustment) by any registered holder hereof (a "Transferor") with respect to
any or all of the Shares. On the surrender for exchange of this Warrant, with
the Transferor's endorsement in the form of Exhibit B attached hereto (the
Transferor Endorsement Form") and together with evidence reasonably satisfactory
to the Company demonstrating compliance with applicable Securities Laws, the
Company at its expense but with payment by the Transferor of any applicable
transfer taxes) will issue and deliver to or on the order of the Transferor
thereof a new Warrant or Warrants of like tenor, in the name of the Transferor
and/or the transferee(s) specified in such Transferor Endorsement Form (each a
"Transferee"), calling in the aggregate on the face or faces thereof for the
number of shares of Common Stock called for on the face or faces of the Warrant
so surrendered by the Transferor.

     8. Replacement of Warrant. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of any such loss, theft or destruction of this Warrant, on
delivery of an indemnity agreement or security reasonably satisfactory in form
and amount to the Company or, in the case of any such mutilation, on surrender
and cancellation of this Warrant, the Company at its expense will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

     9. Registration Rights. The Holder of this Warrant has been granted certain
registration rights by the Company. These registration rights are set forth in a
Subscription Agreement entered into by the Company and Subscribers of the
Company's Common Stock at or prior to the issue date of this Warrant. The terms
of the Subscription Agreement are incorporated herein by this reference. Upon
the occurrence of a Non-Registration Event as described in the Subscription
Agreement, in the event the Company is unable to issue Common Stock upon
exercise of this Warrant that has been registered in the Registration Statement
described in Section 9.4 of the Subscription Agreement, within the time periods
described in the Subscription Agreement, which Registration Statement must be
effective throughout the exercise period of this Warrant, then upon written
demand made by the Holder, then the Company will pay to the Holder of this
Warrant, in lieu of delivering Common Stock, a sum equal to the closing ask
price of the Company's Common Stock on NASD OTC Bulletin Board or such other
principal trading market for the Company's Common Stock on the trading date
immediately preceding the date notice is given by the Holder, less the exercise
price of this Warrant, for each share of Common Stock designated in such notice
from the Holder.

                                       19
<PAGE>


     10. Maximum Exercise. The Holder shall not be entitled to exercise, on an
exercise date, this Warrant in connection with that number of shares of Common
Stock which would be in excess of the sum of (i) the number of shares of Common
Stock beneficially owned by the Holder and its affiliates on an exercise date,
and (ii) the number of shares of Common Stock issuable upon the exercise of this
Warrant with respect to which the determination of this proviso is being made on
an exercise date, which would result in beneficial ownership by the Holder and
its affiliates of more than 9.99% of the outstanding shares of Common Stock of
the Company on such exercise date. For the purposes of the proviso to the
immediately preceding sentence, beneficial ownership shall be determined in
accordance with Section 13(d) of the Securities Exchange Act of 1934, as
amended, and Regulation 13d-3 thereunder. Subject to the foregoing, the Holder
shall not be limited to aggregate exercises which would result in the issuance
of more than 9.99%. The restriction described in this paragraph may be revoked
upon 75 days prior notice from the Holder to the Company. The Holder may
allocate which of the equity of the Company deemed beneficially owned by the
Subscriber shall be included in the 9.99% amount described above and which shall
be allocated to the excess above 9.99%.

     11. Warrant Agent. The Company may, by written notice to the each holder of
the Warrant, appoint an agent for the purpose of issuing Common Stock (or Other
Securities) on the exercise of this Warrant pursuant to Section 1, exchanging
this Warrant pursuant to Section 7, and replacing this Warrant pursuant to
Section 8, or any of the foregoing, and thereafter any such issuance, exchange
or replacement, as the case may be, shall be made at such office by such agent.

     12. Transfer on the Company's Books. Until this Warrant is transferred on
the books of the Company, the Company may treat the registered holder hereof as
the absolute owner hereof for all purposes, notwithstanding any notice to the
contrary.

     13. Notices, etc. All notices and other communications from the Company to
the holder of this Warrant shall be mailed by first class registered or
certified mail, postage prepaid, at such address as may have been furnished to
the Company in writing by such holder or, until any such holder furnishes to the
Company an address, then to, and at the address of, the last holder of this
Warrant who has so furnished an address to the Company.

     14. Miscellaneous. 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. This Warrant shall be construed and enforced in accordance with and
governed by the laws of New York. Any dispute relating to this Warrant shall be
adjudicated in New York State. The headings in this Warrant are for purposes of
reference only, and shall 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.

IN WITNESS WHEREOF, the Company has executed this Warrant under seal as of the
date first written above.
