         Section 2. Exercise of Warrant.

may be exercised by the holder hereof then registered on the books of the
Company, in whole or in part, at any time on any business day on or after the
opening of business on the date hereof and prior to 11:59 P.M. Eastern Time on
the Expiration Date by (i) delivery of a written notice, in the form of the
subscription notice attached as Exhibit A hereto (the "Exercise Notice"), of
such holder's election to exercise this Warrant, which notice shall specify the

                                       2


number of Warrant Shares to be purchased, (ii) (A) payment to the Company of an
amount equal to the Warrant Exercise Price multiplied by the number of Warrant
Shares as to which this Warrant is being exercised (plus any applicable issue or
transfer taxes) (the "Aggregate Exercise Price") in cash or by check or wire
transfer; or (B) by notifying the Company that it should subtract from the
number of Warrant Shares issuable to the holder upon such exercise an amount of
Warrant Shares having a last reported sale price (as reported by Bloomberg) on
the date immediately preceding the date of the subscription notice equal to the
Aggregate Exercise Price of the Warrant Shares for which this Warrant is being
exercised (a "Cashless Exercise"); and (iii) the surrender to a common carrier
for delivery to the Company as soon as practicable following such date, this
Warrant (or an indemnification undertaking with respect to this Warrant in the
case of its loss, theft or destruction); provided, that if such Warrant Shares
are to be issued in any name other than that of the registered holder of this
Warrant, such issuance shall be deemed a transfer and the provisions of Section
7 shall be applicable. In the event of any exercise of the rights represented by
this Warrant in compliance with this Section 2(a), a certificate or certificates
for the Warrant Shares so purchased, in such denominations as may be requested
by the holder hereof and registered in the name of, or as directed by, the
holder, shall be issued as soon as practicable, and in no event later than five
(5) business days after the Company's receipt of the Exercise Notice, the
Aggregate Exercise Price and this Warrant (or an indemnification undertaking
with respect to this Warrant in the case of its loss, theft or destruction), and
deliver the same at the Company's expense to, or as directed by, such holder.
Upon delivery of the Exercise Notice and Aggregate Exercise Price referred to in
clause (ii)(A) above or notification to the Company of a Cashless Exercise
referred to in clause (ii) (B) above, the holder of this Warrant shall be deemed
for all corporate purposes to have become the holder of record of the Warrant
Shares with respect to which this Warrant has been exercised, irrespective of
the date of delivery of this Warrant as required by clause (iii) above or the
certificates evidencing such Warrant Shares. In the case of a dispute as to the
determination of the Warrant Exercise Price, the Company shall promptly issue to
the holder the number of shares of Common Stock that is not disputed and shall
submit the disputed determinations or arithmetic calculations to the holder via
facsimile within five (5) business days of receipt of the holder's subscription
notice. If the holder and the Company are unable to agree upon the determination
of the Warrant Exercise Price or arithmetic calculation of the Warrant Shares
within five (5) business days of such disputed determination or arithmetic
calculation being submitted to the holder, then the Company shall immediately
submit via facsimile (i) the disputed determination of the Warrant Exercise
Price to an independent, reputable investment banking firm or (ii) the disputed
arithmetic calculation of the Warrant Shares to its independent, outside
accountant. The Company shall cause the investment banking firm or the
accountant, as the case may be, to perform the determinations or calculations
and notify the Company and the holder of the results no later than forty-eight
(48) hours from the time it receives the disputed determinations or
calculations. Such investment banking firm's or accountant's determination or
calculation, as the case may be, shall be deemed conclusive absent manifest
error and the Company shall be liable for the costs and expenses related to such
determination or calculation.

                  (b) Unless the rights represented by this Warrant shall have
expired or shall have been fully exercised, the Company shall, as soon as
practicable and in no event later than five (5) business days after any exercise
and at its own expense, issue a new Warrant identical in all respects to this
Warrant exercised except it shall represent rights to purchase the number of
Warrant Shares purchasable immediately prior to such exercise under this Warrant
exercised, less the number of Warrant Shares with respect to which such Warrant
is exercised.

                                       3



                  (c) If the Company shall fail to issue a certificate for the
number of shares of Common Stock to which the holder is entitled upon the
holder's exercise of this Warrant or a new Warrant for the number of shares of
Common Stock to which such holder is entitled pursuant to Section 2(b) hereof on
a timely basis as described in this Section 2 for any reason other than a force
majeure or other cause beyond its reasonable control, the Company shall, in
addition to any other remedies under this Warrant or the Securities Purchase
Agreement or otherwise available to such holder, including any indemnification
under the Securities Purchase Agreement, pay as additional damages in cash to
such holder on each business day the issuance of such Common Stock certificate
or new Warrant, as the case may be, is not timely effected an amount equal to
 .25% of the product of (A) the sum of the number of shares of Common Stock not
issued to the holder on a timely basis and to which the holder is entitled
and/or, the number of shares represented by the portion of this Warrant which is
not being converted, as the case may be, and (B) the average of the closing bid
price of the Common Stock for the three consecutive trading days immediately
preceding the last possible date which the Company could have issued such Common
Stock or Warrant, as the case may be, to the holder without violating this
Section, provided, however, that the maximum number of days in respect of which
the Company shall be liable for such damages shall not exceed the greater of (X)
ten (10) days or (Y) the number of days following the date that the holder gives
notice to the Company (in accordance with the terms of the Securities Purchase
Agreement) of such holder's intention to assert a claim for damages under this
Section 2(c) and the date such violation is cured by the Company.

         Section 3. Covenants as to Common Stock. The Company hereby covenants
and agrees as follows:

                   (a) This Warrant is, and any Warrant issued in substitution
for or replacement of this Warrant will upon issuance be, duly authorized and
validly issued.

                  (b) All Warrant Shares which may be issued upon the exercise
of the rights represented by this Warrant will, upon issuance, be validly
issued, fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issue thereof.

                  (c) During the period within which the rights represented by
this Warrant may be exercised, the Company will at all times have authorized and
reserved at least 100% of the number of shares of Common Stock needed to provide
for the exercise of the rights then represented by this Warrant and the par
value of said shares will at all times be less than or equal to the applicable
Warrant Exercise Price.

                                       4



                  (d) The Company shall promptly secure the listing of the
shares of Common Stock issuable upon exercise of this Warrant upon each national
securities exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed (subject to official notice of issuance upon
exercise of this Warrant) and shall maintain, so long as any other shares of
Common Stock shall be so listed, such listing of all shares of Common Stock from
time to time issuable upon the exercise of this Warrant; and the Company shall
so list on each national securities exchange or automated quotation system, as
the case may be, and shall maintain such listing of, any other shares of capital
stock of the Company issuable upon the exercise of this Warrant if and so long
as any shares of the same class shall be listed on such national securities
exchange or automated quotation system.

                  (e) 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 to be
observed or performed by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other impairment, consistent with the tenor and purpose of
this Warrant will take all such actions as may be necessary or appropriate in
order that the Company may validly and legally issue fully paid and
nonassessable shares of Common Stock upon the exercise of this Warrant.

                  (f) This Warrant will be binding upon any entity succeeding to
the Company by merger, consolidation or acquisition of all or substantially all
of the Company's assets.

         Section 4. Taxes. The Company shall pay any and all taxes which may be
payable with respect to the issuance and delivery of Warrant Shares upon
exercise of this Warrant.

         Section 5. Warrant Holder Not Deemed a Stockholder. Except as otherwise
specifically provided herein, no holder, as such, of this Warrant shall be
entitled to vote or receive dividends or be deemed the holder of shares of the
Company for any purpose, nor shall anything contained in this Warrant be
construed to confer upon the holder hereof, as such, any of the rights of a
stockholder of the Company or any right to vote, give or withhold consent to any
corporate action (whether any reorganization, issue of stock, reclassification
of stock, consolidation, merger, conveyance or otherwise), receive notice of
meetings, receive dividends or subscription rights, or otherwise, prior to the
issuance to the holder of this Warrant of the Warrant Shares which he or she is
then entitled to receive upon the due exercise of this Warrant. In addition,
nothing contained in this Warrant shall be construed as imposing any liabilities
on such holder to purchase any securities (upon exercise of this Warrant or
otherwise) or as a stockholder of the Company, whether such liabilities are
asserted by the Company or by creditors of the Company. Notwithstanding this
Section 5, the Company will provide the holder of this Warrant with copies of
the same notices and other information given to the stockholders of the Company
generally, contemporaneously with the giving thereof to the stockholders.

         Section 6. Representations of Holder.The holder of this Warrant, by the
acceptance hereof, represents that it is acquiring this Warrant and the Warrant
Shares for its own account for investment only and not with a view towards, or
for resale in connection with, the public sale or distribution of this Warrant
or the Warrant Shares, except pursuant to sales registered or exempted under the
Securities Act; provided, however, that by making the representations herein,
the holder does not agree to hold this Warrant or any of the Warrant Shares for

                                       5



any minimum or other specific term and reserves the right to dispose of this
Warrant and the Warrant Shares at any time in accordance with or pursuant to a
registration statement or an exemption under the Securities Act. The holder of
this Warrant further represents, by acceptance hereof, that, as of this date,
such holder is an "accredited investor" as such term is defined in Rule
501(a)(1) of Regulation D promulgated by the Securities and Exchange Commission
under the Securities Act (an "Accredited Investor").

         Section 7. Ownership and Transfer.

                  (a) The Company shall maintain at its principal executive
offices (or such other office or agency of the Company as it may designate by
notice to the holder hereof), a register for this Warrant, in which the Company
shall record the name and address of the person in whose name this Warrant has
been issued, as well as the name and address of each transferee. The Company may
treat the person in whose name any Warrant is registered on the register as the
owner and holder thereof for all purposes, notwithstanding any notice to the
contrary, but in all events recognizing any transfers made in accordance with
the terms of this Warrant.

                   (b) This Warrant and the rights granted to the holder hereof
are transferable, in whole or in part, upon surrender of this Warrant, together
with a properly executed warrant power in the form of Exhibit B attached hereto;
provided, however, that any transfer or assignment shall be subject to the
conditions set forth in Section 7(c) below.

                  (c) The holder of this Warrant understands that this Warrant
has not been and is not expected to be, registered under the Securities Act or
any state securities laws, and may not be offered for sale, sold, assigned or
transferred unless (i) subsequently registered thereunder, or (ii) the
transferee is an affiliated entity that is an Accredited Investor, or (iii) such
holder shall have delivered to the Company an opinion of counsel, in generally
acceptable form, to the effect that the securities to be sold, assigned or
transferred may be sold, assigned or transferred pursuant to Regulation S under
the Securities Act or to an exemption from such registration; provided that (A)
any sale of such securities made in reliance on Rule 144 promulgated under the
Securities Act may be made only in accordance with the terms of said Rule and
further, if said Rule is not applicable, any resale of such securities under
circumstances in which the seller (or the person through whom the sale is made)
may be deemed to be an underwriter (as that term is defined in the Securities
Act) may require compliance with some other exemption under the Securities Act
or the rules and regulations of the Securities and Exchange Commission
thereunder; and (B) neither the Company nor any other person is under any
obligation to register the Warrants under the Securities Act or any state
securities laws or to comply with the terms and conditions of any exemption
thereunder.

                  (d) The Company is obligated to register the Warrant Shares
for resale under the Securities Act pursuant to a Registration Rights Agreement
and between the Company and the holder (the "Registration Rights Agreement") and
the initial holder of this Warrant (and certain assignees thereof) is entitled
to the registration rights in respect of the Warrant Shares as set forth in the
Registration Rights Agreement.

                                       6



         Section 8. Adjustment of Warrant Exercise Price and Number of Shares.
The Warrant Exercise Price and the number of shares of Common Stock issuable
upon exercise of this Warrant shall be adjusted from time to time as follows:

                  (a) [intentionally omitted]

                  (b) [intentionally omitted]

                  (c) [intentionally omitted]

                  (d) Adjustment of Warrant Exercise Price upon Subdivision or
Combination of Common Stock. If the Company at any time after the date of
issuance of this Warrant subdivides (by any stock split, stock dividend,
recapitalization or otherwise) one or more classes of its outstanding shares of
Common Stock into a greater number of shares, the Warrant Exercise Price in
effect immediately prior to such subdivision will be proportionately reduced and
the number of shares of Common Stock obtainable upon exercise of this Warrant
will be proportionately increased. If the Company at any time after the date of
issuance of this Warrant combines (by combination, reverse stock split or
otherwise) one or more classes of its outstanding shares of Common Stock into a
smaller number of shares, the Warrant Exercise Price in effect immediately prior
to such combination will be proportionately increased and the number of shares
of Common Stock obtainable upon exercise of this Warrant will be proportionately
decreased.

                  (e) Distribution of Assets. If the Company shall declare or
make any dividend or other distribution of its assets (or rights to acquire its
assets) to holders of Common Stock, by way of return of capital or otherwise
(including, without limitation, any distribution of cash, stock or other
securities, property or options by way of a dividend, spin off,
reclassification, corporate rearrangement or other transaction) (a
"Distribution"), at any time after the issuance of this Warrant, then, in each
such case:

                           (i) the Warrant Exercise Price in effect immediately
prior to the close of business on the record date fixed for the determination of
holders of Common Stock entitled to receive the Distribution shall be reduced,
effective as of the close of business on such record date, to a price determined
by multiplying such Warrant Exercise Price by a fraction of which (A) the
numerator shall be the Closing bid price on the trading day immediately
preceding such record date minus the value of the Distribution (as determined in
good faith by the Company's Board of Directors) applicable to one share of
Common Stock, and (B) the denominator shall be the Closing bid price on the
trading day immediately preceding such record date; and

                                       7



                           (ii) either (A) the number of Warrant Shares
obtainable upon exercise of this Warrant shall be increased to a number of
shares equal to the number of shares of Common Stock obtainable immediately
prior to the close of business on the record date fixed for the determination of
holders of Common Stock entitled to receive the Distribution multiplied by the
reciprocal of the fraction set forth in the immediately preceding clause (i), or
(B) in the event that the Distribution is of common stock of a company whose
common stock is traded on a national securities exchange or a national automated
quotation system, then the holder of this Warrant shall receive an additional
warrant to purchase Common Stock, the terms of which shall be identical to those
of this Warrant, except that such warrant shall be exercisable into the amount
of the assets that would have been payable to the holder of this Warrant
pursuant to the Distribution had the holder exercised this Warrant immediately
prior to such record date and with an exercise price equal to the amount by
which the exercise price of this Warrant was decreased with respect to the
Distribution pursuant to the terms of the immediately preceding clause (i).

                  (f) Certain Events. If any event occurs of the type
contemplated by the provisions of this Section 8 but not expressly provided for
by such provisions (including, without limitation, the granting of stock
appreciation rights, phantom stock rights or other rights with equity features),
then the Company's Board of Directors will make an appropriate adjustment in the
Warrant Exercise Price and the number of shares of Common Stock obtainable upon
exercise of this Warrant so as to protect the rights of the holders of the
Warrants; provided that no such adjustment will increase the Warrant Exercise
Price or decrease the number of shares of Common Stock obtainable as otherwise
determined pursuant to this Section 8.

                  (g)      Notices.

                           (i) Immediately upon any adjustment of the Warrant
Exercise Price, the Company will give written notice thereof to the holder of
this Warrant, setting forth in reasonable detail, and certifying, the
calculation of such adjustment.

                           (ii) The Company will give written notice to the
holder of this Warrant at least twenty (20) days prior to the date on which the
Company closes its books or takes a record (A) with respect to any dividend or
distribution upon the Common Stock, (B) with respect to any pro rata
subscription offer to holders of Common Stock or (C) for determining rights to
vote with respect to any Organic Change (as defined below), dissolution or
liquidation, provided that such information shall be made known to the public
prior to or in conjunction with such notice being provided to such holder.

                           (iii) The Company will also give written notice to
the holder of this Warrant at least twenty (20) days prior to the date on which
any Organic Change, dissolution or liquidation will take place, provided that
such information shall be made known to the public prior to or in conjunction
with such notice being provided to such holder.

         Section 9. Purchase Rights; Reorganization, Reclassification,
Consolidation, Merger or Sale. (a) In addition to any adjustments pursuant to
Section 8 above, if at any time the Company grants, issues or sells any Options,
Convertible Securities or rights to purchase stock, warrants, securities or
other property pro rata to the record holders of any class of Common Stock (the
"Purchase Rights"), then the holder of this Warrant will be entitled to acquire,
upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights
which such holder could have acquired if such holder had held the number of
shares of Common Stock acquirable upon complete exercise of this Warrant
immediately before the date on which a record is taken for the grant, issuance
or sale of such Purchase Rights, or, if no such record is taken, the date as of
which the record holders of Common Stock are to be determined for the grant,
issue or sale of such Purchase Rights.

                                       8



                  (b) Any recapitalization, reorganization, reclassification,
consolidation, merger, sale of all or substantially all of the Company's assets
to another Person or other transaction which is effected in such a way that
holders of Common Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities or assets with respect to or in
exchange for Common Stock is referred to herein as "Organic Change." Prior to
the consummation of any (i) sale of all or substantially all of the Company's
assets to an acquiring Person or (ii) other Organic Change following which the
Company is not a surviving entity, the Company will secure from the Person
purchasing such assets or the successor resulting from such Organic Change (in
each case, the "Acquiring Entity") written agreement (in form and substance
satisfactory to the holders of Warrants representing a majority of the shares of
Common Stock obtainable upon exercise of the Warrants then outstanding) to
deliver to each holder of Warrants in exchange for such Warrants, a security of
the Acquiring Entity evidenced by a written instrument substantially similar in
form and substance to this Warrant and satisfactory to the holders of the
Warrants (including, an adjusted warrant exercise price equal to the value for
the Common Stock reflected by the terms of such consolidation, merger or sale,
and exercisable for a corresponding number of shares of Common Stock acquirable
and receivable upon exercise of the Warrants, if the value so reflected is less
than the Warrant Exercise Price in effect immediately prior to such
consolidation, merger or sale). Prior to the consummation of any other Organic
Change, the Company shall make appropriate provision (in form and substance
satisfactory to the holders of Warrants representing a majority of the shares of
Common Stock obtainable upon exercise of the Warrants then outstanding) to
insure that each of the holders of the Warrants will thereafter have the right
to acquire and receive in lieu of or in addition to (as the case may be) the
shares of Common Stock immediately theretofore acquirable and receivable upon
the exercise of such holder's Warrants, such shares of stock, securities or
assets that would have been issued or payable in such Organic Change with
respect to or in exchange for the number of shares of Common Stock which would
have been acquirable and receivable upon the exercise of such holder's Warrant
as of the date of such Organic Change (without taking into account any
limitations or restrictions on the exercisability of this Warrant).

         Section 10. Lost, Stolen, Mutilated or Destroyed Warrant. If this
Warrant is lost, stolen, mutilated or destroyed, the Company shall, on receipt
of an indemnification undertaking, issue a new Warrant of like denomination and
tenor as this Warrant so lost, stolen, mutilated or destroyed.

         Section 11. Notice. Any notices, consents, waivers or other
communications required or permitted to be given under the terms of this Warrant
must be in writing and will be deemed to have been delivered: (i) upon receipt,
when delivered personally; (ii) upon receipt, when sent by facsimile (provided
confirmation of transmission is mechanically or electronically generated and
kept on file by the sending party); or (iii) one business day after deposit with
a nationally recognized overnight delivery service, in each case properly
addressed to the party to receive the same. The addresses and facsimile numbers
for such communications shall be as set forth below:
