holder, to the Company at its principal office or at the office of its Warrant
agent (as provided in Section 12), accompanied by payment, in cash or by

                ----------------
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

          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

               (a) If the Company's Common Stock is traded on an exchange or is

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

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

the 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

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 appointed pursuant to Section 12 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,

                                       3
<PAGE>

as the case may be, on exercise of this Warrant pursuant to this Section 1.

          1.7. Exercise by Telecopier.  The exercise date of this Warrant will
               ----------------------
be deemed to be the date the form of subscription attached as Exhibit A is
delivered by telecopier to the Company at its principal office or at the office
of its Warrant Agent (as provided in Section 12) provided that the original form
of subscription and payment are delivered within five business days of
telecopier delivery of the form of subscription.

     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 three business 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 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.

          (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:

                                       4
<PAGE>

               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 3.3, 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

                                       5
<PAGE>

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 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 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 10 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

                                       6
<PAGE>

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/ Shareholder Approval.  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 Series A 5% Preferred Stock at or prior to the
issue date of this Warrant.  The terms of the Subscription Agreement are
incorporated herein by this reference.  The holder of this Warrant may not
exercise his rights hereunder to purchase some or all of the Common Stock
issuable upon exercise of this Warrant until the Company obtains the Approval,
as defined in the Subscription Agreement.  Upon (i) after the occurrence and
during the pendency of a Non-Registration Event as described in the Subscription
Agreement, from and after the Effective Date (as defined in the Subscription
Agreement); or (ii) after the occurrence and during the pendency of an Approval
Default, then, within five days after written demand to the Company from the
Holder, 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 the NASDAQ National Market 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 of this Warrant,
for each share of Common Stock designated in such notice from the Holder.

     10. Call Option.  The Company shall have the option to "call" the Warrants
         -----------
(the "Warrant Call"), in accordance with and governed by the following:

                                       7
<PAGE>

          (a) The Company shall exercise the Warrant Call by giving to each
Warrant Holder a written notice of call (the "Call Notice") during the period in
which the Warrant Call may be exercised.

          (b) The Company's right to exercise the Warrant Call shall commence
with the Actual Effective Date, as defined in Section 11.2(a) of the
Subscription Agreement and thereafter, shall be coterminous with the exercise
period of the Warrants for a maximum of 50% of the Common Stock issuable upon
the exercise of this Warrant (the "Warrant Shares"), provided, that the
registration statement is effective at the date the Call Notice is given and
through the period ending 14 business days thereafter.  In no event may the
Company exercise the Warrant Call at any time unless the Warrant Shares to be
delivered upon exercise of the Warrant, will be upon delivery, immediately
resalable, without restrictive legend and upon such resale freely transferable
on the transfer books of the Company.

          (c) Unless otherwise agreed to by the Warrant Holder, the Call Notices
must be given to all Warrant Holders who receive Warrants similar to this
Warrant on or about the same issue date as this Warrant in proportion to the
amounts of Common Stock which can be purchased by the respective Warrant Holders
in accordance with the respective Warrant held by each.

          (d) The Company may give a Call Notice in connection with up to 25% of
the Common Stock issuable upon exercise of this Warrant provided the closing bid
price of the Common Stock as reported by the NASDAQ National Market for each of
the thirty days prior to the giving of the Call Notice ("Lookback Period") is
200% of the Purchase Price and the average daily trading volume of the Common
Stock during the Lookback Period is not less than 150,000 Common Shares.  A Call
Notice may be given for an additional 25% of the Common Stock issuable upon
exercise of this Warrant provided the average daily trading volume during the
Lookback Period is at least 250,000 Common Shares.

          (e) The respective Warrant Holders shall exercise their Warrant rights
and purchase the appropriate Warrant Shares and pay for same within 14 business
days of the date of the Call Notice.  If the Warrant Holder fails to timely pay
the funds required by the Warrant Call, the Company may elect to cancel a
corresponding amount of this Warrant.

          (f) The Company may not exercise the right to Call this Warrant or any
part of it after the occurrence of a Non-Registration Event or Approval Default,
as defined in the Subscription Agreement, unless same were subject to cure and
cured during the stated cure period.

     11.  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

                                       8
<PAGE>

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 Holder shall be included in the
9.9% amount described above and which shall be allocated to the excess above
9.99%.

     12.  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.

     13.  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.

     14.  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.

     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 construed and enforced in accordance with and
