      corporation hereunder.

            (b)   The term "COMMON STOCK" includes (a) the Company's common

      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   METHOD OF EXERCISE.

            (a)   This Warrant may be exercised in whole or in part (but not as
      to a fractional share of Common Stock), at any time and from time to time
      during the Exercise Period by the Holder hereof by delivery of a notice of
      exercise (a "NOTICE OF EXERCISE") substantially in the form attached
      hereto as EXHIBIT A via facsimile to the Company. Promptly thereafter the
      Holder shall surrender this Warrant (if the entire amount of the Warrant
      is subject to the Notice of Exercise) to the Company at its principal
      office via overnight delivery service, accompanied by payment of the
      Purchase Price multiplied by the number of shares of Common Stock for
      which this Warrant is being exercised (the "EXERCISE PRICE"). Payment of
      the Exercise Price shall be made, at the option of the Holder, (i) by
      check or bank draft payable to the order of the Company, or (ii) by wire
      transfer to the account of the Company. Upon exercise, the Holder shall be
      entitled to receive within three Trading Days after the Exercise Date (as
      defined herein), one or more certificates, issued in the Holder's name or
      in such name or names as the Holder may direct, subject to the limitations
      on transfer contained herein, for the number of shares of Common Stock so
      purchased. The shares of Common Stock so purchased shall be deemed to be
      issued as of the close of business on the date on which the Company shall
      have received from the Holder payment in full of the Exercise Price (the
      "EXERCISE DATE").

                                       3
<PAGE>

            (b)   Upon exercise of a portion of this Warrant in accordance with
      the terms hereof, records showing the amount so exercised and the date of
      exercise shall be maintained on a ledger substantially in the form of
      ANNEX B attached hereto (an originally signed and executed copy of which
      shall be delivered to the Company with each Notice of Exercise). The
      Company shall maintain the originally signed and executed ledger and the
      Holder shall maintain a copy thereof. Upon execution of the exercise of
      the Warrants contemplated by the Notice of Exercise, the Company shall
      deliver to the Holder a copy of ANNEX B signed and executed by the
      Company, and the Holder shall deliver to the Company a copy of Annex B
      signed by the Holder. It is specifically contemplated that the Company
      shall act as the calculation agent for all exercises of this Warrant. The
      Holder and any assignee, by acceptance of this Warrant, acknowledges and
      agrees that, by reason of the provisions of this paragraph, following an
      exercise of a portion of this Warrant, the number of shares of Common
      Stock represented by this Warrant will be the amount indicated on ANNEX B
      attached hereto (which may be less than the amount stated on the face
      hereof).

            (c)   In the event there is a dispute as to the number of shares of
      Common Stock the Holder is entitled to receive upon exercise of this
      Warrant, the Company shall issue to the Holder the number of shares not in
      dispute and the Company and the Holder will use their best efforts to
      resolve such dispute within one Business Day following the receipt of a
      Notice of Exercise. If such dispute cannot be resolved within such one-day
      period, the Company and the Holder shall submit the dispute to an
      independent accountant mutually agreed upon by the Company and the Holder
      to make a final and binding determination of the number of shares owed to
      the Holder. The Company shall issue shares of Common Stock owed to Holder
      as a result of the resolution of the dispute within two Business Days
      following the receipt of the accountant's independent determination.

            (d)   Provided that the Company has obtained and maintained an
      Effective Registration Statement, the Warrants issued to the Holder may be
      called, at the option of the Company, in the following amounts: (i)
      250,000 shares if the Common Stock trades at a VWAP equal to 200% of the
      Purchase Price of the warrants for any five (5) consecutive trading days;
      (ii) 250,000 shares if the Common Stock trades at a VWAP equal to 250% of
      the Purchase Price of the warrants for any five (5) consecutive trading
      days; (iii) 250,000 shares if the Common Stock trades at a VWAP equal to
      300% of the Purchase Price of the warrants for any five (5) consecutive
      trading days; and (iv) 250,000 shares if the Common Stock trades at a VWAP
      equal to 350% of the Purchase Price of the warrants for any five (5)
      consecutive trading days; provided however, that the maximum amount of
      shares which may be called by the Company shall not exceed 250,000 shares
      during any 90 day period following the Closing Date.

            1.2   REGULATION D RESTRICTIONS. The Holder hereof represents and
warrants to the Company that it has acquired this Warrant and anticipates
acquiring the shares of Common Stock issuable upon exercise of the Warrant
solely for its own account for investment purposes and not with a view to or for
resale of such securities unless such resale has been registered with the
Commission or an applicable exemption is available therefor and provided that
the Holder shall have furnished to the Company an opinion of counsel in form and
substance reasonably satisfactory to the Company, to the effect that such
transfer is exempt from the registration requirements of the Securities Act and
any applicable state securities laws.

                                       4
<PAGE>

            1.3   COMPANY ACKNOWLEDGMENT. The Company will, at the time of the
exercise of this Warrant, upon request of the Holder hereof, acknowledge in
writing its continuing obligation to afford to such Holder the registration
rights to which such Holder shall continue to be entitled after such exercise in
accordance with the provisions of a Registration Rights Agreement dated the date
hereof (the "Registration Rights Agreement").

            1.4   LIMITATION ON EXERCISE. Notwithstanding the rights of the
Holder to exercise all or a portion of this Warrant as described herein, such
exercise rights shall be limited, solely to the extent set forth in the Purchase
Agreement as if such provisions were specifically set forth herein. In addition,
the number of shares of Common Stock issuable upon exercise of this Warrant is
subject to reduction as specified in Section 10.3 of the Purchase Agreement.

      2.    DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE. As soon as
practicable after the exercise of this Warrant, and in any event within three
(3) Business Days thereafter, the Company at its expense (including the payment
by it of any applicable issue, stamp or transfer taxes) will cause to be issued
in the name of and delivered to the Holder thereof, or, to the extent
permissible hereunder, to such other person as such Holder may direct, a
certificate or certificates for the number of 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 applicable Purchase Price, 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.

      3.    ADJUSTMENT FOR EXTRAORDINARY EVENTS. The Purchase Price to be paid
by the Holder upon exercise of this Warrant, and the consideration to be
received upon exercise of this Warrant, shall be adjusted in case at any time or
from time to time pursuant to Article 11 of the Purchase Agreement as if such
provisions were specifically set forth herein.

      4.    NO IMPAIRMENT. The Company will not, by amendment of its Certificate
of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of this Warrant, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the Holder of this
Warrant against impairment. Without limiting the generality of the foregoing,
the Company (a) will not increase the par value of any shares of stock
receivable on the exercise of this Warrant above the amount payable therefor on
such exercise, (b) will take all such action as may be necessary or appropriate
in order that the Company may validly and legally issue fully paid and
unassessable shares of stock on the exercise of this Warrant, and (c) will not
transfer all or substantially all of its properties and assets to any other
person (corporate or otherwise), or consolidate with or merge into any other
person or permit any such person to consolidate with or merge into the Company
(if the Company is not the surviving person), unless such other person shall
expressly assume in writing and will be bound by all the terms of this Warrant.

                                       5

      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 this Warrant, the Company will promptly cause its principal
financial officer to compute such adjustment or readjustment in accordance with
the terms of this 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 issue or sale and as adjusted and readjusted
as provided in this Warrant. The Company will forthwith mail a copy of each such
certificate to the Holder of this Warrant, and will, on the written request at
any time of the Holder of this Warrant, furnish to such Holder a like
certificate setting forth the Purchase Price at the time in effect and showing
how it was calculated.

      6.    NOTICES OF RECORD DATE, ETC.

            In the event of

            (a)   any taking by the Company of a record of the Holders of any
      class of securities for the purpose of determining the Holders thereof who
      are entitled to receive any dividend or other distribution, or any right
      to subscribe for, purchase or otherwise acquire any shares of stock of any
      class or any other securities or property, or to receive any other right,

      or

            (c)   any voluntary or involuntary dissolution, liquidation or

stating the amount and character of such dividend, distribution or right, and
(ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding-up is to take place, and the time, if any, as of which the Holders of
record of Common Stock (or Other Securities) shall be entitled to exchange their
shares of Common Stock (or Other Securities) for securities or other property

attached as Annex B.

      9.    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

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.

      10.   REMEDIES. The Company stipulates that the remedies at law of the
Holder of this Warrant in the event of any default or threatened default by the
Company in the performance of or compliance with any of the terms of this
Warrant are not and will not be adequate, and that such terms may be
