which such Warrant may still be exercised.

                  1.4. Fair Market Value. Fair Market Value of a share of

clause (d) that all of the shares of Common Stock then issuable upon exercise of
all of the 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 hall have been appointed as trustee for the holders of the Warrants

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 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) Payment may be made 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, or (ii) by delivery of Warrants, Common Stock and/or
Common Stock receivable upon exercise of the Warrants in accordance with Section
(b) below, 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.

          (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:

                                       3

                           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)

         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.

                  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.

                                       4

<PAGE>

         3.4. Share Issuance. Except for the Excepted Issuances as described in
              --------------
Section 10 of the Purchase Agreement, if the Company at any time shall issue any
shares of Common Stock 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
        -----------------------------
eadjustment 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).

         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


                                       5

<PAGE>

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 Securities Purchase Agreement entered into by the Company and
Purchaser of the Company's 4% Convertible Notes (the "Notes") at or prior to the
issue date of this Warrant. Upon the occurrence of a Non-Registration Event as
described in the Securities Purchase 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 9.1(d) of the
Securities Purchase Agreement, within the time periods described in the
Securities Purchase Agreement, which Registration Statement must be effective
throughout the exercise period of this Warrant, 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 (as defined in the Securities Purchase
Agreement) 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 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 proviso is being made on
an exercise date, which would result in beneficial ownership by the Holder and
its affiliates of more than 4.99% of the outstanding shares of Common Stock of
the Company on such 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 4.99%. The
restriction described in this paragraph may be revoked upon 75 days prior notice
from the Holder to the Company or upon an Event of Default under the Notes. The
Holder may allocate which of the equity of the Company deemed beneficially owned
by the Subscriber shall be included in the 4.99% amount described above and
which shall be allocated to the excess above 4.99%.

         11. Warrant Agent. The Company may, by written notice to the each
             -------------
holder of the Warrant,

                                       6

<PAGE>

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. Voluntary Adjustment by the Company. The company may at any time during
         -----------------------------------
the term of this Warrant reduce the then current Purchase Price to any amount
and for any period of time deemed appropriate by the Board of Directors of the
Company.

     15. 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 governed by and construed in accordance with the
laws of State of New York without regard to principles of conflicts of laws. Any
action brought concerning the transactions contemplated by this Warrant shall be
brought only in the state courts of New York or in the federal courts located in
the state of New York. The individuals executing this Warrant on behalf of the
Company agree to submit to the jurisdiction of such courts and waive trial by
jury. The prevailing party shall be entitled to recover from the other party its
reasonable attorney's fees and costs. In the event that any provision of this
Warrant is invalid or unenforceable under any applicable statute or rule of law,
then such provision shall be deemed inoperative to the extent that it may
conflict therewith and shall be deemed modified to conform with such statute or
rule of law. Any such provision which may prove invalid or unenforceable under
any law shall not affect the validity or enforceability of any other provision
of this Warrant. 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. The Company acknowledges
that legal counsel participated in the preparation of this Warrant and,
therefore, stipulates that the rule of construction that ambiguities are to be
resolved against the drafting party shall not be applied in the interpretation
of this Warrant to favor any party against the other party.
