         1. EXERCISE OF WARRANT.

                  1.1. NUMBER OF SHARES ISSUABLE UPON EXERCISE. From and after
the Issue Date through and including the Expiration Date, the holder hereof
shall be entitled to receive, upon exercise of this Warrant in whole in

then the mean of the closing bid and asked prices reported for the last business
day immediately preceding the Determination Date.

                           (c) Except as provided in clause (d) below, if the

                           (d) If the Determination Date is the date of a

Warrants are outstanding at the Determination Date.

                  1.5. COMPANY ACKNOWLEDGMENT. The Company will, at the time of
the exercise of the Warrant, upon the request of the holder hereof acknowledge
in 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 (as hereinafter described) 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 seven (7) 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
of one full share, together with any other stock or other securities and
property (including cash, where applicable) to which such holder is entitled
upon such exercise pursuant to Section 1 or otherwise.

         2.2. CASHLESS EXERCISE.

                  (a) If a Registration Statement is effective and the Holder
may sell its Shares of Company Common Stock upon exercise hereof thereunder,
this Warrant may be exercisable in whole or in part for cash only as set forth
in Section 1 above. If no such Registration Statement is available, payment upon
exercise may be made at the option of the Holder either in (i) cash or by
certified or official bank check payable to the order of the Company equal to
the applicable aggregate Purchase Price, (ii) by delivery of Common Stock
issuable 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.

<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, upon consent of the Company, 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) The Holder may not employ the cashless exercise feature
described above at any time that the Warrant Stock to be issued upon exercise is
included for unrestricted resale in an effective registration statement.

         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.

                  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.

<PAGE>

                  3.3. CONTINUATION OF TERMS. Upon any reorganization,
consolidation, merger or transfer (and any dissolution following any transfer)
referred to in this Section 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, 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.

                  3.4 SHARE ISSUANCE. If the Company, during the Exclusion
Period (as defined in the Subscription Agreement), shall issue any shares of
Common Stock except for the employee stock options, or in connection with the
exercise of Warrants, options or upon the conversion of convertible instruments
outstanding on the issue date of this Note and as described in the Borrower's
Reports (as defined in the Subscription Agreement) prior to the complete
exercise of this Warrant for a consideration less than the Purchase Price that
would be in effect at the time of such issue, then, and thereafter successively
upon each such issue, the Purchase Price shall be reduced as follows: (i) the
number of shares of Common Stock outstanding immediately prior to such issue
shall be multiplied by the Purchase Price in effect at the time of such issue
and the product shall be added to the aggregate consideration, if any, received
by the Company upon such issue of additional shares of Common Stock; and (ii)
the sum so obtained shall be divided by the number of shares of Common Stock
outstanding immediately after such issue. The resulting quotient shall be the
adjusted Purchase Price. For purposes of this adjustment, the issuance of any
security of the Company carrying the right to convert such security into shares
of Common Stock or of any warrant, right or option to purchase Common Stock
shall result in an adjustment to the Purchase Price upon the issuance of shares
of Common Stock upon exercise of such conversion or purchase rights.

         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
increased 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

                                       5

<PAGE>

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).

         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 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 Subscriber of
the Company's Convertible Notes 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 defined 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 a Registration
Statement described in Section 10 of the Subscription Agreement, within the time
periods described in the Subscription Agreement, which Registration Statement
must be effective for the periods set forth in the Subscription Agreement, then
upon written demand made by the Holder, the Company will pay to the Holder of
this Warrant, in lieu of delivering Common Stock, a sum equal to the closing
price of the Company's Common Stock on the principal market or exchange upon
which the Common Stock is listed for trading on the trading date immediately
preceding the date notice is given by the Holder, less the Purchase Price, for
each share of Common Stock designated in such notice from the Holder.

         10. MAXIMUM EXERCISE. The Holder shall not be entitled to exercise this
Warrant on an exercise date, 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 limitation 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 date. For the purposes of 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 seventy-five (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. All notices, demands, requests, consents, approvals, and
