     As used herein the following terms, unless the context otherwise requires,

$.001 par value per share, as authorized on the date of the Subscription
Agreement referred to in Section 9 hereof, (b) any other capital stock of any
class or classes (however designated) of the Company, authorized on or after
such date, the holders of which shall have the right, without limitation as to
amount, either to all or to a share of the balance of current dividends and
liquidating dividends after the payment of dividends and distributions on any
shares entitled to preference, and the holders of which shall ordinarily, in the
absence of contingencies, be entitled to vote for the election of a majority of
directors of the Company (even if the right so to vote has been suspended by the
happening of such a contingency) and (c) any other securities into which or for
which any of the securities described in (a) or (b) may be converted or
exchanged pursuant to a plan of recapitalization, reorganization, merger, sale
of assets or otherwise.

     (c)    The term "Other Securities" refers to any stock (other than Common

                                       1
<PAGE>

securities of the Company or any other person (corporate or otherwise) which the
holder of the Warrant at any time shall be entitled to receive, or shall have
received, on the exercise of the Warrant, in lieu of or in addition to Common
Stock, or which at any time shall be issuable or shall have been issued in
exchange for or in replacement of Common Stock or Other Securities pursuant to
Section 4 or otherwise.

     1.   Exercise of Warrant.
          -------------------

          1.1.   Number of Shares Issuable upon Exercise.  From and after the
                 ---------------------------------------
date hereof through and including the Expiration Date, the holder hereof shall
be entitled to receive, upon exercise of this Warrant in whole in accordance
with the terms of subsection 1.2 or upon exercise of this Warrant in part in
accordance with subsection 1.3, shares of Common Stock of the Company, subject
to adjustment pursuant to Section 4.

          1.2.   Full Exercise.  This Warrant may be exercised in full by the
                 -------------
holder hereof by delivery of an original or fax copy of the form of subscription
attached as Exhibit A hereto (the "Subscription Form") duly executed by such
holder and surrender of the original Warrant within seven days of exercise, to
the Company at its principal office or at the office of its Warrant agent (as
provided hereinafter), accompanied by payment, in cash, wire transfer, or by
certified or official bank check payable to the order of the Company, in the
amount obtained by multiplying the number of shares of Common Stock for which
this Warrant is then exercisable by the Purchase Price (as hereinafter defined)
then in effect.

          1.3.   Partial Exercise.  This Warrant may be exercised in part (but
                 ----------------
not for a fractional share) by surrender of this Warrant in the manner and at
the place provided in subsection 1.2 except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying (a)
the number of shares of Common Stock designated by the holder in the
Subscription Form by (b) the Purchase Price then in effect. On any such partial
exercise, the Company, at its expense, will forthwith issue and deliver to or
upon the order of the holder hereof a new Warrant of like tenor, in the name of
the holder hereof or as such holder (upon payment by such holder of any
applicable transfer taxes) may request, the number of shares of Common Stock for
which such Warrant may still be exercised.

          1.4.   Fair Market Value.  Fair Market Value of a share of Common
                 -----------------
Stock as of a particular date (the "Determination Date") shall mean the Fair
Market Value of a share of the Company's Common Stock. Fair Market Value of a
share of Common Stock as of a Determination Date shall mean:

                 (a)    If the Company's Common Stock is traded on an exchange
or is quoted on the National Association of Securities Dealers, Inc. Automated
Quotation ("NASDAQ") National Market System or the NASDAQ SmallCap Market, then
the closing or last sale price, respectively, reported for the last business day
immediately preceding the Determination Date.

                 (b)    If the Company's Common Stock is not traded on an
exchange or on the NASDAQ National Market System or the NASDAQ SmallCap Market
but is traded in the over-the-counter market, 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 Company's
Common Stock is not publicly traded, then as the Holder and the Company agree or
in the absence of agreement by arbitration in accordance with the rules then
standing of the American Arbitration Association, before a single arbitrator to
be chosen from a panel of persons qualified by education and training to pass on
the

                                       2
<PAGE>

matter to be decided.

                 (d)    If the Determination Date is the date of a liquidation,
dissolution or winding up, or any event deemed to be a liquidation, dissolution
or winding up pursuant to the Company's charter, then all amounts to be payable
per share to holders of the Common Stock pursuant to the charter in the event of
such liquidation, dissolution or winding up, plus all other amounts to be
payable per share in respect of the Common Stock in liquidation under the
charter, assuming for the purposes of this 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 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 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 (a) 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 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.

                                       3
<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)

     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

                                       4
<PAGE>

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.  Except for the Excepted Issuances as described
                 --------------
in Section 11 of the Subscription 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
          -----------------------------
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

                                       5
<PAGE>

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.   Subscription Agreement.  This Warrant is issued pursuant to a
          ----------------------
Subscription Agreement entered into by the Company and Subscribers of the
Company's 8% Convertible Notes at or prior to the issue date of this Warrant.
The terms of the Subscription Agreement are incorporated herein by this
reference.

     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.  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%.

                                       6

     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.
