                                CONVERTIBLE NOTE

Issuance Date: ____________ __, 200_               Principal: U.S. $____________

         FOR VALUE RECEIVED, VIEWPOINT CORPORATION, a Delaware corporation (the
"COMPANY"), hereby promises to pay to the order of __________________ or
registered assigns ("HOLDER") the amount set out above as the Principal (as
reduced pursuant to the terms hereof pursuant to redemption, conversion or
otherwise, the "PRINCIPAL") when due, whether upon the Maturity Date (as defined
below), acceleration, redemption or otherwise (in each case in accordance with
the terms hereof) and to pay interest ("INTEREST") on any outstanding Principal
at the rate of 4.95% per annum, subject to periodic adjustment pursuant to
Section 2 (the "INTEREST RATE"), from the date set out above as the Issuance
Date (the "ISSUANCE DATE") until the same becomes due and payable, whether upon
an Interest Date (as defined below), the Maturity Date (as defined below),
acceleration, conversion, redemption or otherwise (in each case in accordance
with the terms hereof). This Convertible Note (including all Convertible Notes
issued in exchange, transfer or replacement hereof, this "NOTE") is one of an
issue of Convertible Notes (collectively, the "NOTES" and such other Convertible
Notes, the "OTHER NOTES") issued on the Issuance Date pursuant to the Securities
Purchase Agreement (as defined below). Certain capitalized terms are defined in
Section 29.
<PAGE>
                  (1) MATURITY. On the Maturity Date, the Holder shall surrender
this Note to the Company and the Company shall pay to the Holder an amount in
cash representing all outstanding Principal, accrued and unpaid Interest and
accrued and unpaid Late Charges, if any. The "MATURITY DATE" shall be December
31, 2007 as extended at the option of the Holder (i) in the event that, and for
so long as, an Event of Default (as defined in Section 4(a)) shall have occurred
and be continuing or any event shall have occurred and be continuing which with
the passage of time and the failure to cure would result in an Event of Default
and (ii) through the date that is ten days after the consummation of a Change of
Control (as defined in Section 5(a)) in the event that a Change of Control is
publicly announced or a Change of Control Notice (as defined in Section 5(a)) is
delivered prior to the Maturity Date.

                  (2) INTEREST; INTEREST RATE. Interest on this Note shall
commence accruing on the Issuance Date and shall be computed on the basis of a
365-day year and actual days elapsed and shall be payable in arrears on the
first day of each Calendar Quarter during the period beginning on the Issuance
Date and ending on, and including, the Maturity Date (each, an "INTEREST DATE").
Interest shall be payable on each Interest Date in cash or, at the option of the
Company, in shares of Common Stock ("INTEREST SHARES") provided that the
Interest which accrued during any period shall be payable in Interest Shares
only if the Company delivers written notice of such election ("INTEREST ELECTION
NOTICE") to each holder of the Notes and the Separate Tranche Notes at least
seven (7) Trading Days prior to the Interest Date (an "INTEREST ELECTION DATE").
Interest to be paid on an Interest Date in Interest Shares shall be paid in a
number of fully paid and nonassessable shares (rounded to the nearest whole
share in accordance with Section 3(a)) of Common Stock equal to the quotient of
(a) the Interest payable and (b) the Interest Conversion Price on the applicable
Interest Date. If any Interest Shares are to be paid on an Interest Date, then
the Company shall (X) issue and deliver on the applicable Interest Date, to such
address as specified by the Holder in writing to the Company at least two
Business Days prior to the applicable Interest Date, a certificate, registered
in the name of the Holder or its designee, for the number of Interest Shares to
which the Holder shall be entitled, or (Y) provided that the Company's transfer
agent (the "TRANSFER AGENT") is participating in the Depository Trust Company
("DTC") Fast Automated Securities Transfer Program, upon the request of the
Holder, credit such aggregate number of Interest Shares to which the Holder
shall be entitled to the Holder's or its designee's balance account with DTC
through its Deposit Withdrawal Agent Commission system. Notwithstanding the
foregoing, the Company shall not be entitled to pay Interest in Interest Shares
and shall be required to pay such Interest in cash on the applicable Interest
Date if (x) any event constituting an Event of Default or an event that with the
passage of time and assuming it were not cured would constitute an Event of
Default has occurred and is continuing on the applicable Interest Election Date
or the Interest Date, unless consented to in writing by the Holder, (y) the
Registration Statement (as defined in the Registration Rights Agreement)
covering the Interest Shares is not effective and available for the resale of
all of the Registrable Securities (as defined in the Registration Rights
Agreement) relating to this Note on the Interest Election Date or on the
Interest Date or (z) the Company has not obtained the Stockholder Approval (as
defined in the Securities Purchase Agreement) prior to the Interest

                                       2
<PAGE>
Election Date. Prior to the payment of Interest on an Interest Date, Interest on
this Note shall accrue at the Interest Rate and be payable upon conversion by
way of inclusion of the Interest in the Conversion Amount in accordance with
Section 3(b)(i). From and after the occurrence of an Event of Default, the
Interest Rate shall be increased to 12%. In the event that such Event of Default
is subsequently cured, the adjustment referred to in the preceding sentence
shall cease to be effective as of the date of such cure; provided that the
Interest as calculated at such increased rate during the continuance of such
Event of Default shall continue to apply to the extent relating to the days
after the occurrence of such Event of Default through and including the date of
cure of such Event of Default. The Company shall pay any and all documentary
stamp, transfer or similar taxes that may be payable with respect to the
issuance and delivery of Interest Shares.

                  (3) CONVERSION OF NOTES. This Note shall be convertible into
shares of the Company's common stock, par value $0.001 per share (the "COMMON
STOCK"), on the terms and conditions set forth in this Section 3.

                        (a) Conversion Right. Subject to the provisions of
Section 3(d), at any time or times on or after the Issuance Date, the Holder
shall be entitled to convert any portion of the outstanding and unpaid
Conversion Amount (as defined below) into fully paid and nonassessable shares of
Common Stock in accordance with Section 3(c), at the Conversion Rate (as defined
below). The Company shall not issue any fraction of a share of Common Stock upon
any conversion. If the issuance would result in the issuance of a fraction of a
share of Common Stock, the Company shall round such fraction of a share of
Common Stock up to the nearest whole share. The Company shall pay any and all
documentary stamp, transfer or similar taxes that may be payable with respect to
the issuance and delivery of Common Stock upon conversion of any Conversion
Amount.

                        (b) Conversion Rate. The number of shares of Common
Stock issuable upon conversion of any Conversion Amount pursuant to Section 3(a)
shall be determined by dividing (x) such Conversion Amount by (y) the Conversion
Price (as defined below) (the "CONVERSION RATE").

        (i) "CONVERSION AMOUNT" means the sum of (A) the portion of the
        Principal to be converted, redeemed or otherwise with respect to which
        this determination is being made, (B) accrued and unpaid Interest with
        respect to such Principal and (C) accrued and unpaid Late Charges with
        respect to such Principal and Interest.

        (ii) "CONVERSION PRICE" means, as of any Conversion Date (as defined
        below) or other date of determination, and subject to adjustment as
        provided herein, [$_____](1).

--------
(1) Insert $2.71 (as appropriately adjusted for any stock splits, stock
dividends, stock combinations and other similar transactions of the Common Stock
which occur after the Initial Issuance Date and other adjustments pursuant to
Section 7(a)(vi)).

                        (c) Mechanics of Conversion.

        (i) Optional Conversion. To convert any Conversion Amount into shares of
        Common Stock on any date (a "CONVERSION DATE"), the Holder shall (A)
        transmit by facsimile (or otherwise deliver), for receipt on or prior to
        11:59 p.m., New York Time, on such date, a copy of an executed notice of
        conversion in the form attached hereto as Exhibit I (the "CONVERSION
        NOTICE") to the Company and (B) if required by Section 3(c)(iii),
        surrender this Note to a common carrier for delivery to the Company as
        soon as practicable on or following such date (or an indemnification
        undertaking with respect to this Note in the case of its loss, theft or
        destruction). On or before the first Business Day following the date of
        receipt of a Conversion Notice, the Company shall transmit by facsimile
        a confirmation of receipt of such Conversion Notice to the Holder and
        the Transfer Agent. On or before the second Business Day following the
        date of receipt of a Conversion Notice (the "SHARE DELIVERY DATE"), the
        Company shall (X) issue and deliver to the address as specified in the
        Conversion Notice, a certificate, registered in the name of the Holder
        or its designee, for the number of shares of Common Stock to which the
        Holder shall be entitled, or (Y) provided that the Transfer Agent is
        participating in DTC Fast Automated Securities Transfer Program, upon
        the request of the Holder, credit such aggregate number of shares of
        Common Stock to which the Holder shall be entitled to the Holder's or
        its designee's balance account with DTC through its Deposit Withdrawal
        Agent Commission system. If this Note is physically surrendered for
        conversion as required by Section 3(c)(iii) and the outstanding
        Principal of this Note is greater than the Principal portion of the
        Conversion Amount being converted, then the Company shall as soon as
        practicable and in no event later than three Business Days after receipt
        of this Note and at its own expense, issue and deliver to the holder a
        new Note (in accordance with Section 19(d)) representing the outstanding
        Principal not converted. The Person or Persons entitled to receive the
        shares of Common Stock issuable upon a conversion of this Note shall be
        treated for all purposes as the record holder or holders of such shares
        of Common Stock on the Conversion Date.

        (ii) Company's Failure to Timely Convert. If the Company shall fail to
        issue a certificate to the Holder or credit the Holder's balance account
        with DTC for the number of shares of Common Stock to which the Holder is
        entitled upon conversion of any Conversion Amount on or prior to the
        date which is five Business Days after the Conversion Date (a
        "CONVERSION FAILURE"), then (A) the Company shall pay damages to the
        Holder for each date of such Conversion Failure in an amount equal to
        1.0% of the product of (I) the sum of the number of shares of Common
        Stock not issued to the Holder on or prior to the Share Delivery Date
        and to which the Holder is entitled, and (II) the Closing Sale Price of
        the Common Stock on the Share Delivery Date and (B) the Holder, upon
        written notice to the Company, may void its Conversion Notice with
        respect to, and retain or have returned, as the case may be, any portion
        of this Note that has not been converted pursuant to such Conversion
        Notice; provided that the voiding of a Conversion Notice shall not
        affect the Company's obligations to make any payments which have

                                       4
<PAGE>
        accrued prior to the date of such notice pursuant to this Section
        3(c)(ii) or otherwise.

        (iii) Book-Entry. Notwithstanding anything to the contrary set forth
        herein, upon conversion of any portion of this Note in accordance with
        the terms hereof, the Holder shall not be required to physically
        surrender this Note to the Company unless (A) the full Conversion Amount
        represented by this Note is being converted or (B) the Holder has
        provided the Company with prior written notice (which notice may be
        included in a Conversion Notice) requesting physical surrender and
        reissue of this Note. The Holder and the Company shall maintain records
        showing the Principal, Interest, and Late Charges converted and the
        dates of such conversions or shall use such other method, reasonably
        satisfactory to the Holder and the Company, so as not to require
        physical surrender of this Note upon conversion.

        (iv) Pro Rata Conversion; Disputes. In the event that the Company
        receives a Conversion Notice from more than one holder of Notes or
        Separate Tranche Notes for the same Conversion Date and the Company can
        convert some, but not all, of such portions of the Notes submitted for
        conversion, the Company, subject to Section 3(d), shall convert from
        each holder of Notes or Separate Tranche Notes electing to have Notes or
        Separate Tranche Notes converted on such date a pro rata amount of such
        holder's portion of its Notes or Separate Tranche Notes submitted for
        conversion based on the principal amount of Notes and Separate Tranche
        Notes submitted for conversion on such date by such holder relative to
        the aggregate principal amount of all Notes and Separate Tranche Notes
        submitted for conversion on such date. In the event of a dispute as to
        the number of shares of Common Stock issuable to the Holder in
        connection with a conversion of this Note, the Company shall issue to
        the Holder the number of shares of Common Stock not in dispute and
        resolve such dispute in accordance with Section 24.

                        (d) Limitations on Conversions.

        (i) Beneficial Ownership. The Company shall not effect any conversion of
        this Note, and the Holder of this Note shall not have the right to
        convert any portion of this Note pursuant to Section 3(a), to the extent
        that after giving effect to such conversion, the Holder (together with
        the Holder's affiliates) would beneficially own in excess of 4.99% of
        the number of shares of Common Stock outstanding immediately after
        giving effect to such conversion. For purposes of the foregoing
        sentence, the number of shares of Common Stock beneficially owned by the
        Holder and its affiliates shall include the number of shares of Common
        Stock issuable upon conversion of this Note with respect to which the
        determination of such sentence is being made, but shall exclude the
        number of shares of Common Stock which would be issuable upon (A)
        conversion of the remaining, nonconverted portion of this Note
        beneficially owned by the Holder or any of its affiliates and (B)
        exercise or conversion of the unexercised or nonconverted portion of any
        other securities of the Company (including, without limitation, any
        Other Notes, Separate Tranche Notes or warrants) subject to a limitation
        on conversion or exercise analogous to

                                       5
<PAGE>
        the limitation contained herein beneficially owned by the Holder or any
        of its affiliates. Except as set forth in the preceding sentence, for
        purposes of this Section 3(d)(i), beneficial ownership shall be
        calculated in accordance with Section 13(d) of the Securities Exchange
        Act of 1934, as amended. For purposes of this Section 3(d)(i), in
        determining the number of outstanding shares of Common Stock, the Holder
        may rely on the number of outstanding shares of Common Stock as
        reflected in (x) the Company's most recent Form 10-Q or Form 10-K, as
        the case may be, (y) a more recent public announcement by the Company or
        (z) any other notice by the Company or the Transfer Agent setting forth
        the number of shares of Common Stock outstanding. For any reason at any
        time, upon the written or oral request of the Holder, the Company shall
        within two Business Days confirm in writing to the Holder the number of
        shares of Common Stock then outstanding. In any case, the number of
        outstanding shares of Common Stock shall be determined after giving
        effect to the conversion or exercise of securities of the Company,
        including this Note, by the Holder or its affiliates since the date as
        of which such number of outstanding shares of Common Stock was reported.

        (ii) Principal Market Regulation. The Company shall not be obligated to
        issue any shares of Common Stock upon conversion of this Note if the
        issuance of such shares of Common Stock would exceed that number of
        shares of Common Stock which the Company may issue upon conversion of
        the Notes and the Separate Tranche Notes without breaching the Company's
        obligations under the rules or regulations of the Principal Market (the
        "EXCHANGE CAP"), except that such limitation shall not apply in the
        event that the Company obtains the approval of its stockholders as
        required by the applicable rules of the Principal Market for issuances
        of Common Stock in excess of such amount. Until such approval is
        obtained, no purchaser of the Notes or Separate Tranche Notes pursuant
        to the Securities Purchase Agreement (the "PURCHASERS") shall be issued,
        upon conversion of Notes or Separate Tranche Notes, shares of Common
        Stock in an amount greater than the product of the Exchange Cap
        multiplied by a fraction, the numerator of which is the principal amount
        of Notes issued to such Purchaser pursuant to the Securities Purchase
        Agreement on the Initial Issuance Date and the denominator of which is
        the aggregate principal amount of all Notes issued to the Purchasers
        pursuant to the Securities Purchase Agreement on the Initial Issuance
        Date (with respect to each Purchaser, the "EXCHANGE CAP ALLOCATION"). In
        the event that any Purchaser shall sell or otherwise transfer any of
        such Purchaser's Notes or Separate Tranche Notes, the transferee shall
        be allocated a pro rata portion of such Purchaser's Exchange Cap
        Allocation, and the restrictions of the prior sentence shall apply to
        such transferee with respect to the portion of the Exchange Cap
        Allocation allocated to such transferee. In the event that any holder of
        Notes or Separate Tranche Notes shall convert all of such holder's Notes
        or Separate Tranche Notes into a number of shares of Common Stock which,
        in the aggregate, is less than such holder's Exchange Cap Allocation,
        then the difference between such holder's Exchange Cap Allocation and
        the number of shares of Common Stock actually issued to such holder
        shall be allocated to the respective Exchange Cap Allocations of the
        remaining holders of Notes and Separate Tranche Notes

                                       6
<PAGE>
        on a pro rata basis in proportion to the aggregate principal amount of
        the Notes and Separate Tranche Notes then held by each such holder.

                  (4) RIGHTS UPON EVENT OF DEFAULT.

                        (a) Event of Default. Each of the following events shall
constitute an "EVENT OF DEFAULT":

        (i) the failure of the applicable Registration Statement required to be
        filed pursuant to the Registration Rights Agreement to be declared
        effective by the SEC on or prior to the date that is 60 days after the
        applicable Effectiveness Deadline (as defined in the Registration Rights
        Agreement), or, while the applicable Registration Statement is required
        to be maintained effective pursuant to the terms of the Registration
        Rights Agreement, the effectiveness of the applicable Registration
        Statement lapses for any reason (including, without limitation, the
        issuance of a stop order) or is unavailable to any holder of the Notes
        for sale of all of such holder's Registrable Securities (as defined in
        the Registration Rights Agreement) in accordance with the terms of the
        Registration Rights Agreement, and such lapse or unavailability
        continues for a period of 10 consecutive days or for more than an
        aggregate of 30 days in any 365-day period (other than days during an

        five consecutive days or for more than an aggregate of 10 days in any
        365-day period;

        (iii) the Company's (A) failure to cure a Conversion Failure by delivery

        any holder of the Notes, including by way of public announcement or
        through any of its agents, at any time, of its intention not to comply

        that is tendered in accordance with the provisions of the Notes;

        (iv) upon the Company's receipt of a Conversion Notice, the Company is
        not obligated to issue shares of Common Stock upon such conversion due
        to the provisions of Section 3(d)(ii);

        (v) at any time following the tenth consecutive Business Day that the
        Holder's Authorized Share Allocation is less than the number of shares
        of Common Stock that the Holder would be entitled to receive upon a

        any limitations on conversion set forth in Section 3(d) or otherwise);

        or the Control Agreement (as defined in the Pledge Agreement), except,
        in the case of a failure to pay Interest and Late Charges and such other
        amounts when and as due, in which case only if such failure continues
        for a period of at least five Business Days;

        (vii) any default under, redemption of or acceleration prior to maturity
        of any Indebtedness (as defined in Section 3(r) of the Securities

        defined in Section 3(a) of the Securities Purchase Agreement) other than

        respect to Purchase Money Indebtedness;

        (viii) the Company or any of its Subsidiaries, pursuant to or within the

        the relief of debtors (collectively, "BANKRUPTCY LAW"), (A) commences a
        voluntary case, (B) consents to the entry of an order for relief against
        it in an involuntary case, (C) consents to the appointment of a
        receiver, trustee, assignee, liquidator or similar official (a

        Act) seeking to adjudicate it a bankrupt or insolvent, or seeking
        dissolution, liquidation, winding up, reorganization, arrangement,
        adjustment, protection, relief of debtors, or seeking the entry of an
        order for relief or the appointment of a Custodian for the Company or
        any such Subsidiary or for any substantial part of its assets or
        properties, and either such proceeding shall remain undismissed or

        proceeding (including, without limitation, the entry of an order for

        thereof, bonded, discharged or stayed pending appeal, or are not
        discharged within 60 days after the expiration of such stay; provided,
        however, that any judgment which is covered by insurance or an indemnity
        from a credit worthy party shall not be included in calculating the
        $1,000,000 amount set forth above so long as the Company provides the
        Holder a written statement from such insurer or indemnity provider
        (which written statement shall be reasonably satisfactory to the Holder)
        to the effect that such judgment is covered by insurance or an indemnity
        and the Company will receive the proceeds of such insurance or indemnity
        within 30 days of the

                                       8
<PAGE>
        issuance of such judgment;

        (xi) the Company breaches any representation, warranty, covenant or
        other term or condition of the Securities Purchase Agreement, the
        Registration Rights Agreement, this Note, the Other Notes, the Separate
        Tranche Notes, the Pledge Agreement, the Control Agreement or any other
        agreement, document, certificate or other instrument delivered in
        connection with the transactions contemplated thereby and hereby to
        which the Holder is a party, except to the extent that such breach would
        not have a Material Adverse Effect (as defined in Section 3(a) of the
        Securities Purchase Agreement) and except, in the case of a breach of a
        covenant which is curable, only if such breach continues for a period of
        at least five consecutive Business Days;

        (xii) any breach or failure in any respect to comply with Section 15 of
        this Note;

        (xiii) any Event of Default (as defined in the Other Notes or the
        Separate Tranche Notes) occurs with respect to any Other Notes or
        Separate Tranche Notes; or

        (xiv) the Company shall, directly or indirectly, repay, prepay, redeem,
        defease or otherwise make any payment on any Indebtedness (other than
        Purchase Money Indebtedness) existing on the Initial Issuance Date
        (including, without limitation, any Indebtedness due to Computer
        Associates International, Inc. or any of its affiliates) in cash or cash
        equivalents.

                        (b) Redemption Right. Promptly after the occurrence of
an Event of Default with respect to this Note or any Other Note, the Company
shall deliver written notice thereof via facsimile and overnight courier (an
"EVENT OF DEFAULT NOTICE") to the Holder. At any time after the earlier of the
Holder's receipt of an Event of Default Notice and the Holder becoming aware of
an Event of Default, the Holder may require the Company to redeem all or any
portion of this Note by delivering written notice thereof (the "EVENT OF DEFAULT
REDEMPTION NOTICE") to the Company, which Event of Default Redemption Notice
shall indicate the portion of this Note the Holder is electing to redeem. Each
portion of this Note subject to redemption by the Company pursuant to this
Section 4(b) shall be redeemed by the Company at a price equal to the greater of
(i) the product of (x) the Conversion Amount to be redeemed and (y) the
Redemption Premium and (ii) the product of (A) the Conversion Rate with respect
to such Conversion Amount in effect at such time as the Holder delivers an Event
of Default Redemption Notice and (B) the Closing Sale Price of the Common Stock
on the date immediately preceding such Event of Default (the "EVENT OF DEFAULT
REDEMPTION PRICE"). Redemptions required by this Section 4(b) shall be made in
accordance with the provisions of Section 12.

                  (5) RIGHTS UPON CHANGE OF CONTROL.

                        (a) Change of Control. Each of the following events
shall constitute a "CHANGE OF CONTROL":

        (i) the consolidation, merger or other business combination (including,
        without limitation, a reorganization or recapitalization) of the Company
        with or into another Person (other than (A) a consolidation, merger or
        other business combination (including, without limitation,
        reorganization or recapitalization) in which holders of the Company's
        voting power immediately prior to the transaction continue after the
        transaction to hold, directly or indirectly, the voting power of the
        surviving entity or entities necessary to elect a majority of the
        members of the board of directors (or their equivalent if other than a
        corporation) of such entity or entities, or (B) pursuant to a migratory
        merger effected solely for the purpose of changing the jurisdiction of
        incorporation of the Company);

        (ii) the sale or transfer of all or substantially all of the Company's
        assets; or

        (iii) a purchase, tender or exchange offer made to and accepted by the
        holders of more than the 50% of the outstanding shares of Common Stock.

No sooner than the public announcement of such Change of Control nor later than
10 days prior to the consummation of a Change of Control, the Company shall
deliver written notice thereof via facsimile and overnight courier to the Holder
(a "CHANGE OF CONTROL NOTICE").

                        (b) Assumption. Prior to the consummation of any Change
of Control, the Company will secure from any Person purchasing the Company's
assets or Common Stock or any successor resulting from such Change of Control
(in each case, an "ACQUIRING ENTITY") a written agreement (in form and substance
reasonably satisfactory to the holders of Notes representing at least two-thirds
of the aggregate principal amount of the Notes then outstanding) to deliver to
each holder of Notes in exchange for such Notes, a security of the Acquiring
Entity evidenced by a written instrument substantially similar in form and
substance to the Notes, including, without limitation, having a principal amount
and interest rate equal to the principal amounts and the interest rates of the
Notes held by such holder, and reasonably satisfactory to the holders of Notes
representing at least two-thirds of the principal amount of the Notes then
outstanding. In the event that an Acquiring Entity is directly or indirectly
controlled by a company or entity whose common stock or similar equity interest
is listed, designated or quoted on a securities exchange or trading market, the
holders of Notes representing at least two-thirds of the aggregate principal
amount of the Notes then outstanding may elect to treat such Person as the
Acquiring Entity for purposes of this Section 5(b).

                        (c) Holder Redemption Right. At any time during the
period beginning after the Holder's receipt of a Change of Control Notice and
ending on the date of the consummation of such Change of Control (or, in the
event a Change of Control Notice is not

                                       10
<PAGE>
delivered at least 10 days prior to a Change of Control, at any time on or after
the date which is 10 days prior to a Change of Control and ending 10 days after
the consummation of such Change of Control), the Holder may require the Company
to redeem all or any portion of this Note by delivering written notice thereof
("CHANGE OF CONTROL REDEMPTION NOTICE") to the Company, which Change of Control
Redemption Notice shall indicate the Conversion Amount the Holder is electing to
redeem. The portion of this Note subject to redemption pursuant to this Section
5(c) shall be redeemed by the Company at a price equal to the greater of (i) the
product of (x) the Conversion Amount being redeemed and (y) the quotient
determined by dividing (A) the Closing Sale Price of the Common Stock
immediately following the public announcement of such proposed Change of Control
by (B) the Conversion Price and (ii) 115% of the Conversion Amount being
redeemed (the "CHANGE OF CONTROL REDEMPTION PRICE"). Redemptions required by
this Section 5(c) shall be made in accordance with the provisions of Section 12
and shall have priority to payments to other stockholders in connection with a
Change of Control.

                        (d) Acquiring Entity Redemption Right. At any time from
and after the delivery of a Change of Control Notice but not later than the day
immediately preceding the consummation of such Change of Control, the Acquiring
Entity may deliver a written notice via facsimile and overnight courier to the
Holder indicating that if the Company shall not receive from the Holder a Change
of Control Redemption Notice in accordance with Section 5(c), then the Acquiring
Entity is electing to redeem all, but not less than all, of this Note, all Other
Notes and all Separate Tranche Notes (an "ACQUIRING ENTITY CHANGE OF CONTROL
REDEMPTION NOTICE"). The Acquiring Entity Change of Control Redemption Notice
shall be irrevocable. If the Company shall not receive from the Holder a Change
of Control Redemption Notice in accordance with Section 5(c) and the Conditions
to Acquiring Entity Redemption (as set forth below) are satisfied or waved in
writing by the Holder, then this Note shall be redeemed by the Acquiring Entity
at a price equal to the greater of (i) the Change of Control Redemption Price
and (ii) the Note Valuation Amount (the "ACQUIRING ENTITY CHANGE OF CONTROL
REDEMPTION PRICE"). Notwithstanding the foregoing, the Holder may continue to
convert this Note into Common Stock pursuant to Section 3(a) on or prior to the
date immediately preceding the Acquiring Entity Change of Control Redemption
Date. Redemptions required by this Section 5(d) shall be made in accordance with
the provisions of Section 12 and shall have priority to payments to other
stockholders in connection with a Change of Control. "CONDITIONS TO ACQUIRING
ENTITY REDEMPTION" means the following conditions: (i) on each day during the
period beginning on the date of delivery of the Acquiring Entity Change of
Control Redemption Notice to each holder of the Notes and Separate Tranche Notes
and ending on and including the date immediately preceding the Acquiring Entity
Change of Control Redemption Date, no Grace Period (as defined in the
Registration Rights Agreement) shall be in effect and either (x) the
Registration Statement or Registration Statements required pursuant to the
Registration Rights Agreement shall be effective and available for the sale for
all of the Registrable Securities in accordance with the terms of the
Registration Rights Agreement or (y) all shares of Common Stock issuable upon
conversion of the Notes and the Separate Tranche Notes and shares of Common
Stock issuable upon exercise of the Warrants and the Separate Tranche Warrants
shall be eligible for sale without restriction pursuant to Rule 144(k) and the
state securities laws, (ii)

                                       11
<PAGE>
the Company shall have no knowledge of any fact that would cause (x) the
Registration Statements required pursuant to the Registration Rights Agreement
not to be effective and available for the sale of at least all of the
Registrable Securities in accordance with the terms of the Registration Rights
Agreement or (y) any shares of Common Stock issuable upon conversion or
redemption of the Notes and the Separate Tranche Notes and shares of Common
Stock issuable upon exercise of the Warrants and the Separate Tranche Warrants
not to be eligible for sale without restriction pursuant to Rule 144(k) and any
applicable state securities laws; (iii) on each day during the period beginning
on the date of delivery of the Acquiring Entity Change of Control Redemption
Notice and ending on and including the date immediately preceding the Acquiring
Entity Change of Control Redemption Date, the Common Stock is designated for
quotation on the Principal Market, the NYSE or the AMEX and shall not have been
suspended from trading on such exchange or market nor shall delisting or
suspension by such exchange or market been threatened or pending either (A) in
writing by such exchange or market or (B) by falling below the minimum listing
maintenance requirements of such exchange or market; (iv) during the period
beginning on the Initial Issuance Date and ending on and including the date
immediately preceding the Acquiring Entity Change of Control Redemption Date,
the Company shall have delivered shares of Common Stock upon any conversion of
Conversion Amounts on a timely basis as set forth in Section 3(c)(i) of this
Note (and analogous provisions under the Other Notes) and the Separate Tranche
Notes and delivered shares of Common Stock upon exercise of any Warrants and the
Separate Tranche Warrants on a timely basis as set forth in Section 1(a) of the
Warrants and the Separate Tranche Warrants; (v) the Company has obtained the
Stockholder Approval prior to the date of delivery of the Acquiring Entity
Change of Control Redemption Notice; and (vi) the Company otherwise shall have
been in material compliance with and shall not have breached, in any material
respect, any provision, covenant, representation or warranty of the Securities
Purchase Agreement, the Registration Rights Agreement, any of the Warrants or
the Separate Tranche Warrants, the Pledge Agreement, the Control Agreement or
any of the Notes or Separate Tranche Notes.

                  (6) RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER
CORPORATE EVENTS.

                        (a) Purchase Rights. 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 will be entitled
to acquire, upon the terms applicable to such Purchase Rights, the aggregate
Purchase Rights which the Holder could have acquired if the Holder had held the
number of shares of Common Stock acquirable upon complete conversion of this
Note (without taking into account any limitations or restrictions on the
convertibility of this Note) 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.

                                       12
<PAGE>
                        (b) Other Corporate Events. Prior to the consummation of
any recapitalization, reorganization, consolidation, merger, spin-off or other
business combination (other than a Change of Control) pursuant to which holders
of Common Stock are entitled to receive securities or other assets with respect
to or in exchange for Common Stock (a "CORPORATE EVENT"), the Company shall make
appropriate provision to insure that the Holder will thereafter have the right
to receive upon a conversion of this Note, (i) in addition to the shares of
Common Stock receivable upon such conversion, such securities or other assets to
which the Holder would have been entitled with respect to such shares of Common
Stock had such shares of Common Stock been held by the Holder upon the
consummation of such Corporate Event or (ii) in lieu of the shares of Common
Stock otherwise receivable upon such conversion, such securities or other assets
received by the holders of Common Stock in connection with the consummation of
such Corporate Event in such amounts as the Holder would have been entitled to
receive had this Note initially been issued with conversion rights for the form
of such consideration (as opposed to shares of Common Stock) at a conversion
rate for such consideration commensurate with the Conversion Rate. Provision
made pursuant to the preceding sentence shall be in a form and substance
reasonably satisfactory to the holders of Notes representing at least two-thirds
of the aggregate principal amount of the Notes then outstanding.

                  (7) RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

                        (a) Adjustment of Conversion Price upon Issuance of
Common Stock. If and whenever on or after the Initial Issuance Date, the Company
issues or sells, or in accordance with this Section 7(a) is deemed to have
issued or sold, any shares of Common Stock (including the issuance or sale of
shares of Common Stock owned or held by or for the account of the Company, but
excluding shares of Common Stock deemed to have been issued or sold by the
Company (I) in connection with any employee benefit plan which has been approved
by the Board of Directors of the Company, pursuant to which the Company's
securities may be issued to any employee, officer or director for services
provided to the Company (an "APPROVED STOCK PLAN"), (II) upon conversion of the
Notes or the Separate Tranche Notes or upon exercise of the Warrants or the
Separate Tranche Warrants, (III) in connection with the payment of any Interest
Shares on the Notes or (IV) in connection with any Excluded Security) for a
consideration per share less than a price (the "APPLICABLE PRICE") equal to the
Conversion Price in effect immediately prior to such issue or sale (the
foregoing, a "DILUTIVE ISSUANCE"), then immediately after such issue or sale,
the Conversion Price then in effect shall be reduced to an amount equal to the
Applicable Price. For purposes of determining the adjusted Conversion Price
under this Section 7(a), the following shall be applicable:

        (i) Issuance of Options. If the Company in any manner grants or sells
        any Options and the lowest price per share for which one share of Common
        Stock is issuable upon the exercise of any such Option or upon
        conversion or exchange or exercise of any Convertible Securities
        issuable upon exercise of such Option is less than the Applicable Price,
        then such share of Common Stock shall be deemed to be outstanding and to
        have

                                       13
<PAGE>
        been issued and sold by the Company at the time of the granting or sale
        of such Option for such price per share. For purposes of this Section
        7(a)(i), the "lowest price per share for which one share of Common Stock
        is issuable upon the exercise of any such Option or upon conversion or
        exchange or exercise of any Convertible Securities issuable upon
        exercise of such Option" shall be equal to the sum of the lowest amounts
        of consideration (if any) received or receivable by the Company with
        respect to any one share of Common Stock upon granting or sale of the
        Option, upon exercise of the Option and upon conversion or exchange or
        exercise of any Convertible Security issuable upon exercise of such
        Option. No further adjustment of the Conversion Price shall be made upon
        the actual issuance of such Common Stock or of such Convertible
        Securities upon the exercise of such Options or upon the actual issuance
        of such Common Stock upon conversion or exchange or exercise of such
        Convertible Securities.

        (ii) Issuance of Convertible Securities. If the Company in any manner
        issues or sells any Convertible Securities and the lowest price per
        share for which one share of Common Stock is issuable upon such
        conversion or exchange or exercise thereof is less than the Applicable
        Price, then such share of Common Stock shall be deemed to be outstanding
        and to have been issued and sold by the Company at the time of the
        issuance of sale of such Convertible Securities for such price per
        share. For the purposes of this Section 7(a)(ii), the "price per share
        for which one share of Common Stock is issuable upon such conversion or
        exchange or exercise" shall be equal to the sum of the lowest amounts of
        consideration (if any) received or receivable by the Company with
        respect to any one share of Common Stock upon the issuance or sale of
        the Convertible Security and upon the conversion or exchange or exercise
        of such Convertible Security. No further adjustment of the Conversion
        Price shall be made upon the actual issuance of such Common Stock upon
        conversion or exchange or exercise of such Convertible Securities, and
        if any such issue or sale of such Convertible Securities is made upon
        exercise of any Options for which adjustment of the Conversion Price had
        been or are to be made pursuant to other provisions of this Section
        7(a), no further adjustment of the Conversion Price shall be made by
        reason of such issue or sale.

        (iii) Change in Option Price or Rate of Conversion. If the purchase
        price provided for in any Options, the additional consideration, if any,
        payable upon the issue, conversion, exchange or exercise of any
        Convertible Securities, or the rate at which any Convertible Securities
        are convertible into or exchangeable or exercisable for Common Stock
        changes at any time, the Conversion Price in effect at the time of such
        change shall be adjusted to the Conversion Price which would have been
        in effect at such time had such Options or Convertible Securities
        provided for such changed purchase price, additional consideration or
        changed conversion rate, as the case may be, at the time initially
        granted, issued or sold. For purposes of this Section 7(a)(iii), if the
        terms of any Option or Convertible Security that was outstanding as of
        the Initial Issuance Date are changed in the manner described in the
        immediately preceding sentence, then such Option or Convertible Security
        and the Common Stock deemed issuable upon exercise, conversion or
        exchange

                                       14
<PAGE>
        thereof shall be deemed to have been issued as of the date of such
        change. No adjustment shall be made if such adjustment would result in
        an increase of the Conversion Price then in effect.

        (iv) Calculation of Consideration Received. In case any Option is issued
        in connection with the issue or sale of other securities of the Company,
        together comprising one integrated transaction in which no specific
        consideration is allocated to such Options by the parties thereto, the
        Options will be deemed to have been issued for a consideration of $.01.
        If any Common Stock, Options or Convertible Securities are issued or
        sold or deemed to have been issued or sold for cash, the consideration
        received therefor will be deemed to be the gross amount received by the
        Company therefor. If any Common Stock, Options or Convertible Securities
        are issued or sold for a consideration other than cash, the amount of
        the consideration other than cash received by the Company will be the
        fair value of such consideration, except where such consideration
        consists of securities, in which case the amount of consideration
        received by the Company will be the Closing Sale Price of such
        securities on the date of receipt. If any Common Stock, Options or
        Convertible Securities are issued to the owners of the non-surviving
        entity in connection with any merger in which the Company is the
        surviving entity, the amount of consideration therefor will be deemed to
        be the fair value of such portion of the net assets and business of the
        non-surviving entity as is attributable to such Common Stock, Options or
        Convertible Securities, as the case may be. The fair value of any
        consideration other than cash or securities will be determined in good
        faith by the Board of Directors of the Company. The holders of Notes and
        Separate Tranche Notes representing at least two-thirds of the principal
        amounts of the Notes and Separate Tranche Notes then outstanding shall
        be entitled to dispute the determination of the Board of Directors of
        the Company. If such holders and the Company are unable to reach
        agreement within ten days after the occurrence of an event requiring
        valuation (the "VALUATION EVENT"), the fair value of such consideration
        will be determined within five Business Days after the tenth day
        following the Valuation Event by an independent, reputable appraiser
        jointly selected by the Company and the holders of Notes representing at
        least two-thirds of the principal amounts of the Notes and Separate
        Tranche Notes then outstanding. The determination of such appraiser
        shall be deemed binding upon all parties absent manifest error and the
        fees and expenses of such appraiser shall be borne equally by the
        Company and the holders.

        (v) Record Date. If the Company takes a record of the holders of Common
        Stock for the purpose of entitling them (A) to receive a dividend or
        other distribution payable in Common Stock, Options or in Convertible
        Securities or (B) to subscribe for or purchase Common Stock, Options or
        Convertible Securities, then such record date will be deemed to be the
        date of the issue or sale of the shares of Common Stock deemed to have
        been issued or sold upon the declaration of such dividend or the making
        of such other distribution or the date of the granting of such right of
        subscription or purchase, as the case may be.

                                       15
<PAGE>
        (vi) This Note Deemed Outstanding. If during the period beginning on and
        including the Initial Issuance Date and ending on the date immediately
        preceding the Issuance Date, the Company entered into, or in accordance
        with Section 7(a) would have been deemed to have entered into (had this
        Note been outstanding at such time), any Dilutive Issuance, then solely
        for purposes of determining any adjustment under this Section 7(a) as a
        result of such Dilutive Issuance or deemed Dilutive Issuance, this Note
        shall be deemed to have been outstanding at the time of each such
        Dilutive Issuance or deemed Dilutive Issuance.]

                        (b) Adjustment of Conversion Price upon Subdivision or
Combination of Common Stock. If the Company at any time 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
Conversion Price in effect immediately prior to such subdivision will be
proportionately reduced. If the Company at any time 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 Conversion Price in effect
immediately prior to such combination will be proportionately increased.

                        (c) Other Events. (i) If any event occurs of the type
contemplated by the provisions of this Section 7 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
Conversion Price so as to protect the rights of the Holder under this Note;
provided that no such adjustment will increase the Conversion Price as otherwise
determined pursuant to this Section 7. (ii) In the event that the Holder has
participated in any dividend or distribution in accordance with the terms of
Section 16, no other adjustment shall be made to the Conversion Price pursuant
to this Section 7.

                  (8) HOLDER RIGHT OF OPTIONAL REDEMPTION.

                        (a) Holder Initial Redemption Option. If at any time
during the Holder Initial Redemption Period, the Weighted Average Price of the
Common Stock is less than the Conversion Price for any 25 consecutive Trading
Days (a "HOLDER INITIAL REDEMPTION MEASURING PERIOD"), the Holder shall have the
right, in its sole discretion, to require that the Company redeem all or any
portion of this Note (a "HOLDER INITIAL REDEMPTION") by delivering written
notice thereof (a "HOLDER INITIAL REDEMPTION NOTICE") to the Company at any time
during the Holder Initial Redemption Period, which Holder Initial Redemption
Notice shall indicate the Conversion Amount the Holder is electing to redeem.
The portion of this Note subject to redemption pursuant to this Section 8(a)
shall be redeemed by the Company at a price equal to the Conversion Amount being
redeemed (the "HOLDER INITIAL REDEMPTION PRICE"). Redemptions required by this
Section 8(a) shall be made in accordance with the provisions of Section 12.

                                       16
<PAGE>
                        (b) Holder Secondary Redemption Option. If at any time
during the Holder Secondary Redemption Period, the Weighted Average Price of the
Common Stock is less than the Conversion Price for any 25 consecutive Trading
Days, the Holder shall have the right, in its sole discretion, to require that
the Company redeem all or any portion of this Note (a "HOLDER SECONDARY
REDEMPTION") by delivering written notice thereof (a "HOLDER SECONDARY
REDEMPTION NOTICE") to the Company at any time during the Holder Secondary
Redemption Period, which Holder Secondary Redemption Notice shall indicate the
Conversion Amount the Holder is electing to redeem. The portion of this Note
subject to redemption pursuant to this Section 8(b) shall be redeemed by the
Company at a price equal to the product derived by multiplying (x) .83 by (y)
the sum of (i) the Principal being redeemed, (ii) accrued and unpaid Interest
with respect to such Principal and (iii) accrued and unpaid Late Charges with
respect to such Principal and Interest on the Conversion Amount being redeemed
(the "HOLDER SECONDARY REDEMPTION PRICE"). Redemptions required by this Section
8(b) shall be made in accordance with the provisions of Section 12.

                        (c) Definitions.

                                (i) "HOLDER INITIAL REDEMPTION PERIOD" means the
period commencing on and including the twenty-fifth (25th) Trading Day prior to
June 30, 2004 and ending on and including the twenty-fourth (24th) Trading Day
after January 1, 2006.

                                (ii) "HOLDER SECONDARY REDEMPTION PERIOD" means
the period commencing on and including January 1, 2006 and ending on and
including the Maturity Date.

                        (d) Partial Redemption In Shares. The Company shall have
the option to indicate in a notice delivered to all holders of Notes, no later
than the close of business on the fifth (5th) consecutive Trading Day that
comprises the first five(5) Trading Days of a Holder Initial Redemption
Measuring Period during which the Weighted Average Price of the Common Stock is
less than the Conversion Price, the percentage, if any (not to exceed 20%) (the
"COMPANY REDEMPTION SHARE PERCENTAGE"), of the applicable Holder Initial
Redemption Price that the Company shall satisfy through the delivery of shares
of Common Stock upon receipt of Holder Initial Redemption Notices (a "COMPANY
REDEMPTION SHARE ELECTION"). Each Company Redemption Share Election shall be
irrevocable. The number of shares of Common Stock to be delivered in connection
with a Company Redemption Share Election shall equal a number of fully paid and
nonassessable shares (rounded to the nearest whole share in accordance with
Section 3(a)) of Common Stock equal to the quotient of (x) the applicable
portion of the Holder Initial Redemption Price, if any, and (b) the Redemption
Conversion Price. If any portion of the Holder Initial Redemption Price is to be
paid in shares of Common Stock, then the Company shall, on the Initial
Redemption Date, (X) issue and deliver to the address as specified in the Holder
Initial Redemption Notice a certificate, registered in the name of the Holder or
its designee, for the number of shares of Common Stock to which the Company is

                                       17
<PAGE>
required to issue and deliver pursuant to a Company Redemption Share Election,
or (Y) provided that the Transfer Agent is participating in DTC Fast Automated
Securities Transfer Program, upon the request of the Holder, credit such
aggregate number of shares of Common Stock to which the Company is required to
issue and deliver pursuant to a Company Redemption Share Election to the
Holder's or its designee's balance account with DTC through its Deposit
Withdrawal Agent Commission system. Notwithstanding the foregoing, the Company
shall not be entitled to pay any of the Holder Initial Redemption Price in
shares of Common Stock and shall be required to pay such Holder Initial
Redemption Price entirely in cash if the Conditions to Holder Initial Redemption
in Shares are not satisfied. "CONDITIONS TO HOLDER INITIAL REDEMPTION IN SHARES"
means the following conditions: (i) during the period beginning on the Initial
Issuance Date and ending on and including the date immediately preceding the
Initial Redemption Date, the Company shall have delivered shares of Common Stock
upon any conversion of Conversion Amounts on a timely basis as set forth in
Section 3(c)(i) of this Note (and analogous provisions under the Other Notes)
and the Separate Tranche Notes and delivered shares of Common Stock upon
exercise of any Warrants and the Separate Tranche Warrants on a timely basis as
set forth in Section 1(a) of the Warrants and the Separate Tranche Warrants;

Holder Initial Redemption Period and ending on and including the Initial
Redemption Date, the Common Stock shall be listed on the Principal Market, the

not have been threatened either (A) in writing by such market or exchange or (B)
by falling below the minimum listing maintenance requirements of such market or
exchange; (iii) during the period beginning on the Initial Issuance Date and
ending on and including the Initial Redemption Date, there shall not have
occurred either (x) the public announcement of a pending, proposed or intended
Change of Control which has not been abandoned, terminated or consummated or (y)
an Event of Default; (iv) during the period beginning on the first Trading Day
of the Holder Initial Redemption Period and ending on and including the Initial
Redemption Date, there shall not have occurred an event that with the passage of
time or giving of notice would constitute an Event of Default; (v) any of the
shares of Common Stock to be issued in payment of the Holder Initial Redemption
Price shall be either (x) registered pursuant to an effective Registration
Statement available for the sale for all of such shares of Common Stock in
accordance with the terms set forth in the Registration Rights Agreement or (y)
eligible for sale without restriction pursuant to Rule 144(k) and any applicable
state securities laws; (vi) the Company shall have no knowledge of any fact that
would cause (x) the Registration Statements required pursuant to the
Registration Rights Agreement not to be effective and available for the sale of
at least all of the Registrable Securities (including the shares of Common Stock
to be delivered pursuant to a Company Redemption Share Election) in accordance
with the terms of the Registration Rights Agreement or (y) any shares of Common
Stock issuable upon conversion or redemption of the Notes and the Separate
Tranche Notes and shares of Common Stock issuable upon exercise of the Warrants
and the Separate Tranche Warrants not to be eligible for sale without
restriction pursuant to Rule 144(k) and any applicable state securities laws;
(vii) the Company otherwise shall have been in material compliance with and

<PAGE>
Agreement, any of the Warrants or Separate Tranche Warrants, the Pledge
Agreement, the Control Agreement or any of the Notes or Separate Tranche Notes;

Company Redemption Share Election.

                  (9) COMPANY'S RIGHT OF MANDATORY CONVERSION; COMPANY OPTIONAL
REDEMPTION.

                        (a) Company's Right of Mandatory Conversion.

                                (i) Mandatory Conversion. If at any time from
and after April 15, 2004, the arithmetic average of the Weighted Average Price
of the Common Stock exceeds 150% of the Conversion Price as of the Issuance Date
(subject to appropriate adjustments for stock splits, stock dividends, stock
combinations and other similar transactions after the Issuance Date and for
purposes of this Section 9, not taking into account any adjustment pursuant to
Section 7(a)(vi) above) for any 25 consecutive Trading Days following April 15,
2004 (the "MANDATORY CONVERSION MEASURING PERIOD") and the Conditions to
Mandatory Conversion (as set forth in Section 9(a)(iii)) are satisfied or waived
in writing by the Holder, the Company shall have the right to require the Holder
to convert all or any such portion of the Conversion Amount of this Note
designated in the Mandatory Conversion Notice into fully paid, validly issued
and nonassessable shares of Common Stock in accordance with Section 3(c) hereof
at the Conversion Rate as of the Mandatory Conversion Date (as defined below) (a
"MANDATORY CONVERSION"). The Company may exercise its right to require
conversion under this Section 9(a) by delivering within not more than three
Trading Days following the end of such Mandatory Conversion Measuring Period a
written notice thereof by facsimile and overnight courier to all, but not less
than all, of the holders of Notes and Separate Tranche Notes and the Transfer
Agent (the "MANDATORY CONVERSION NOTICE" and the date all of the holders
received such notice is referred to as the "MANDATORY CONVERSION NOTICE DATE").
The Mandatory Conversion Notice shall be irrevocable.

                                (ii) Pro Rata Conversion Requirement. If the
Company elects to cause a conversion of all or any portion of the Conversion
Amount of this Note pursuant to Section 9(a)(i), then it must simultaneously
take the similar action with respect to the Other Notes. If the Company elects
to cause the conversion of this Note pursuant to Section 9(a)(i) (or similar
provisions under the Other Notes) with respect to less than all of the
Conversion Amounts of the Notes then outstanding, then the Company shall require
conversion of a Conversion Amount from each of the holders of the Notes equal to
the product of (I) the aggregate Conversion Amount of Notes which the Company
has elected to cause to be converted pursuant to Section 9(a)(i), multiplied by
(II) the fraction, the numerator of which is the sum of the aggregate principal
amount of the Notes initially purchased by such holder on the Issuance Date and
the denominator of which is the sum of the aggregate principal amount of the
Notes purchased by all holders on the Issuance Date (such fraction with respect
to each holder is referred to as its "ALLOCATION PERCENTAGE", and such amount
with respect to each holder is referred to as its "PRO RATA CONVERSION AMOUNT").
In the event that the initial holder of any

                                       19
<PAGE>
Notes shall sell or otherwise transfer any of such holder's Notes, the
transferee shall be allocated a pro rata portion of such holder's Allocation
Percentage. The Mandatory Conversion Notice shall state (A) the Trading Day
selected for the Mandatory Conversion in accordance with Section 9(a)(i), which
Trading Day shall be at least 20 Business Days but not more than 60 Business
Days following the Mandatory Conversion Notice Date (the "MANDATORY CONVERSION
DATE"), (B) the aggregate Conversion Amount of the Notes which the Company has
elected to be subject to mandatory conversion from all of the holders of the
Notes pursuant to this Section 9(a) (and analogous provisions under the Other
Notes), (C) each holder's Pro Rata Conversion Amount of the Conversion Amount of
the Notes the Company has elected to cause to be converted pursuant to this
Section 9(a) (and analogous provisions under the Other Notes) and (D) the number
of shares of Common Stock to be issued to such Holder as of the Mandatory
Conversion Date. All Conversion Amounts converted by the Holder after the
Mandatory Conversion Notice Date shall reduce the Conversion Amount of this Note
required to be converted on the Mandatory Conversion Date. If the Company has
elected a Mandatory Conversion, the mechanics of conversion set forth in Section
3(c) shall apply, to the extent applicable, as if the Company and the Transfer
Agent had received from the Holder on the Mandatory Conversion Date a Conversion
Notice with respect to the Conversion Amount being converted pursuant to the
Mandatory Conversion.

                                (iii) Conditions to Mandatory Conversion. For
purposes of this Section 9(a), "CONDITIONS TO MANDATORY CONVERSION" means the
following conditions: (A) during the period beginning on the Initial Issuance
Date and ending on and including the Mandatory Conversion Date, the Company
shall have delivered shares of Common Stock upon any conversion of Conversion
Amounts on a timely basis as set forth in Section 3(c)(i) of this Note (and
analogous provisions under the Other Notes) and the Separate Tranche Notes and
delivered shares of Common Stock upon exercise of any Warrants and the Separate
Tranche Warrants on a timely basis as set forth in Section 1(a) of the Warrants
and the Separate Tranche Warrants; (B) on each day during the period beginning
on the first Trading Day of the Mandatory Conversion Measuring Period, and
ending on and including the Mandatory Conversion Date, the Common Stock shall be
listed on the Principal Market, the NYSE or the AMEX and delisting or suspension
by such market or exchange shall not have been threatened either (I) in writing
by such market or exchange or (II) by falling below the minimum listing
maintenance requirements of such market or exchange; (C) during the period
beginning on the Initial Issuance Date and ending on and including the Mandatory
Conversion Date, there shall not have occurred either (I) the public
announcement of a pending, proposed or intended Change of Control which has not
been abandoned, terminated or consummated or (II) an Event of Default; (D)
during the period beginning on the date which is the first Trading Day of the
Mandatory Conversion Measuring Period and ending on and including the Mandatory
Conversion Date, there shall not have occurred an event that with the passage of
time or giving of notice would constitute an Event of Default; (E) on each day
of the period beginning on the date of delivery of the Mandatory Conversion
Notice and ending on the Mandatory Conversion Date either (I) the Registration
Statement or Registration Statements required pursuant to the Registration
Rights Agreement shall be effective and available for the sale for all of the

                                       20
<PAGE>
Registrable Securities in accordance with the terms of the Registration Rights
Agreement or (II) all shares of Common Stock issuable upon conversion of the
Notes and the Separate Tranche Notes and shares of Common Stock issuable upon
exercise of the Warrants and the Separate Tranche Warrants shall be eligible for
sale without restriction pursuant to Rule 144(k) and any applicable state
securities laws, (F) the Company shall have no knowledge of any fact that would
cause (I) the Registration Statements required pursuant to the Registration
Rights Agreement not to be effective and available for the sale of at least all
of the Registrable Securities in accordance with the terms of the Registration
Rights Agreement or (II) any shares of Common Stock issuable upon conversion or
redemption of the Notes and the Separate Tranche Notes and shares of Common
Stock issuable upon exercise of the Warrants and the Separate Tranche Warrants
not to be eligible for sale without restriction pursuant to Rule 144(k) and any
applicable state securities laws, and (G) the Company otherwise shall have been
in material compliance with and shall not have breached, in any material
respect, any provision, covenant, representation or warranty of the Securities
Purchase Agreement, the Registration Rights Agreement, any of the Warrants or
the Separate Tranche Warrants, the Pledge Agreement, the Control Agreement or
any of the Notes or Separate Tranche Notes.

                        (b) Company Optional Redemption Right.

                                (i) Company Optional Redemption. If at any time
from and after the 30 month anniversary of the day the Registration Statement
relating to the Conversion Shares, Interest Shares and any other shares of
Common Stock issuable in connection with this Note and the Other Notes is
declared effective by the SEC, the Conditions to Company Redemption (as set
forth below) are satisfied or waived in writing by the Holder, the Company shall
have the right to redeem this Note (a "COMPANY OPTIONAL REDEMPTION"). The
Company may exercised its right of redemption under this Section 9(b)(i) by
delivering a written notice thereof by facsimile and overnight courier to all of
the holders of Notes and the Transfer Agent (the "COMPANY OPTIONAL REDEMPTION
NOTICE", and, collectively with a Event of Default Redemption Notice, a Change
of Control Redemption Notice, an Acquiring Entity Change of Control Redemption
Notice, a Holder Initial Redemption Notice and a Holder Secondary Redemption
Notice, "REDEMPTION NOTICES" and, individually, each, a "REDEMPTION NOTICE")).
The Company shall not issue a Company Optional Redemption Notice with respect to
this Note and the Other Notes to the extent that any Separate Tranche Notes with
a conversion price that is greater than the Conversion Price pursuant to this
Note and the Other Notes shall remain outstanding. The Company Optional
Redemption Notice shall be irrevocable. This Note shall be redeemed by the
Company pursuant to this Section 9(b)(i) at a price equal to the greater of (i)
the Conversion Amount and (ii) the Note Valuation Amount (the "COMPANY OPTIONAL
REDEMPTION PRICE" and, together with the Event of Default Redemption Price, the
Change of Control Redemption Price, the Acquiring Entity Change of Control
Redemption Price, the Holder Initial Redemption Price, the Holder Secondary
Redemption Price, the "REDEMPTION PRICE"). Notwithstanding the foregoing, the
Holder may continue to convert this Note into Common Stock pursuant to Section
3(a) on or prior to the date immediately preceding the Company Optional
Redemption Date. Redemptions required by this Section 9(b) shall be made

                                       21
<PAGE>
in accordance with the provisions of Section 12.

                                (ii) Pro Rata Redemption Requirement. If the
Company elects to cause a redemption of all or any portion of the Conversion
Amount of this Note pursuant to Section 9(b)(i), then it must simultaneously
take the similar action with respect to the Other Notes. If the Company elects
to cause the redemption of this Note pursuant to Section 9(b)(i) (or similar
provisions under the Other Notes) with respect to less than all of the
Conversion Amounts of the Notes then outstanding, then the Company shall redeem
a Conversion Amount from each of the holders of the Notes equal to the product
of (I) the aggregate Conversion Amount of Notes which the Company has elected to
redeem pursuant to Section 9(b)(i) (or similar provisions under the Other
Notes), multiplied by (II) a fraction, the numerator of which is the sum of the
aggregate principal amount of the Notes initially purchased by such holder on
the applicable Issuance Date and the denominator of which is the sum of the
aggregate principal amount of the Notes purchased by all holders on the
applicable Issuance Date (such fraction with respect to each holder is referred
to as its "REDEMPTION ALLOCATION PERCENTAGE", and such amount with respect to
each holder is referred to as its "PRO RATA REDEMPTION AMOUNT"). In the event
that the initial holder of any Notes shall sell or otherwise transfer any of
such holder's Notes, the transferee shall be allocated a pro rata portion of
such holder's Redemption Allocation Percentage. The Company Optional Redemption
Notice shall state (A) the Trading Day selected for the Company Optional
Redemption in accordance with Section 9(b)(i), which Trading Day shall be at
least 20 Business Days but not more than 60 Business Days following the Company
Optional Redemption Notice Date (the "COMPANY OPTIONAL REDEMPTION DATE"), (B)
the aggregate Conversion Amount of the Notes which the Company has elected to
redeem from all of the holders of the Notes pursuant to this Section 9(b) (and
analogous provisions under the Other Notes), (C) each holder's Pro Rata
Redemption Amount of the Conversion Amount of the Notes the Company has elected
to redeem pursuant to this Section 9(b) (and analogous provisions under the
Other Notes) and (D) the Company Optional Redemption Price to be paid to such
Holder as of the Company Optional Redemption Date. All Conversion Amounts
converted by the Holder after delivery of the Company Optional Redemption Notice
Date shall reduce the Conversion Amount of this Note required to be redeemed on
the Company Optional Redemption Date. Redemptions required by this Section 9(b)
shall be made in accordance with the provisions of Section 12.

                                (iii) Conditions to Company Redemption. For
purposes of this Section 9(b), "CONDITIONS TO COMPANY REDEMPTION" means the
following conditions: (i) on each day during the period beginning on the date of
delivery of the Company Optional Redemption Notice to each holder of the Notes
and ending on and including the date immediately preceding the Company Optional
Redemption Date, no Grace Period (as defined in the Registration Rights
Agreement) shall be in effect and either (x) the Registration Statement or
Registration Statements required pursuant to the Registration Rights Agreement
shall be effective and available for the sale for all of the Registrable
Securities in accordance with the terms of the Registration Rights Agreement or
(y) all shares of Common Stock issuable upon conversion and redemption of the
Notes and the Separate Tranche Notes and shares of Common

                                       22
<PAGE>
Stock issuable upon exercise of the Warrants and the Separate Tranche Warrants
shall be eligible for sale without restriction pursuant to Rule 144(k) and any
applicable state securities laws, (ii) the Company shall have no knowledge of
any fact that would cause (x) the Registration Statements required pursuant to
the Registration Rights Agreement not to be effective and available for the sale
of at least all of the Registrable Securities in accordance with the terms of
the Registration Rights Agreement or (y) any shares of Common Stock issuable
upon conversion or redemption of the Notes and the Separate Tranche Notes and
shares of Common Stock issuable upon exercise of the Warrants and the Separate
Tranche Warrants not to be eligible for sale without restriction pursuant to
Rule 144(k) and any applicable state securities laws; (iii) on each day during
the period beginning on the date of delivery of the Company Optional Redemption
Notice to each holder of the Notes and ending on and including the date
immediately preceding the Company Optional Redemption Date, the Common Stock is
designated for quotation on the Principal Market, the NYSE or the AMEX and shall
not have been suspended from trading on such exchange or market nor shall
delisting or suspension by such exchange or market been threatened or pending
either (A) in writing by such exchange or market or (B) by falling below the
minimum listing maintenance requirements of such exchange or market; (iv) during
the period beginning on the Initial Issuance Date and ending on and including
the date immediately preceding the Company Optional Redemption Date, the Company
shall have delivered shares of Common Stock upon any conversion of Conversion
Amounts on a timely basis as set forth in Section 3(c)(i) of this Note (and
analogous provisions under the Other Notes) and the Separate Tranche Notes and
delivered shares of Common Stock upon exercise of any Warrants and the Separate
Tranche Warrants on a timely basis as set forth in Section 1(a) of the Warrants
and the Separate Tranche Warrants; (v) the Company has obtained the Stockholder
Approval prior to the date of delivery of the Company Optional Redemption
Notice; (vi) during the period beginning on the Initial Issuance Date and ending
on and including the Company Optional Redemption Date, there shall not have
occurred either (x) the public announcement of a pending, proposed or intended
Change of Control which has not been abandoned, terminated or consummated or (y)
an Event of Default; and (vii) the Company otherwise shall have been in material
compliance with and shall not have breached, in any material respect, any
provision, covenant, representation or warranty of the Securities Purchase
Agreement, the Registration Rights Agreement, any of the Warrants or the
Separate Tranche Warrants, the Pledge Agreement, the Control Agreement or any of
the Notes or Separate Tranche Notes.

                  (10) NONCIRCUMVENTION. The Company hereby covenants and agrees
that 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 Note,
and will at all times in good faith carry out all of the provisions of this
Note.

                  (11) RESERVATION OF AUTHORIZED SHARES.

                        (a) Reservation. The Company shall initially reserve out
of its

                                       23
<PAGE>
authorized and unissued Common Stock a number of shares of Common Stock for each
of the Notes equal to 130% of the Conversion Rate with respect to the Conversion
Amount of each such Note as of the Issuance Date. Thereafter, the Company shall,
so long as any of the Notes are outstanding, take all action necessary to
reserve and keep available out of its authorized and unissued Common Stock,
solely for the purpose of effecting the conversion of the Notes, 110% of the
number of shares of Common Stock as shall from time to time be necessary to
effect the conversion of all of the Notes then outstanding; provided that at no
time shall the number of shares of Common Stock so reserved be less than the
number of shares required to be reserved by the previous sentence (without
regard to any limitations on conversions) (the "REQUIRED RESERVE AMOUNT"). The
initial number of shares of Common Stock reserved for conversions of the Notes
and each increase in the number of shares so reserved shall be allocated pro
rata among the holders of the Notes based on the principal amount of the Notes
held by each holder at the time of Issuance Date or increase in the number of
reserved shares, as the case may be (the "AUTHORIZED SHARE ALLOCATION"). In the
event that a holder shall sell or otherwise transfer any of such holder's Notes,
each transferee shall be allocated a pro rata portion of such holder's
Authorized Share Allocation. Any shares of Common Stock reserved and allocated
to any Person which ceases to hold any Notes shall be allocated to the remaining
holders of Notes, pro rata based on the principal amount of the Notes then held
by such holders.

                        (b) Insufficient Authorized Shares. If at any time while
any of the Notes remain outstanding the Company does not have a sufficient
number of authorized and unreserved shares of Common Stock to satisfy its
obligation to reserve for issuance upon conversion of the Notes at least a
number of shares of Common Stock equal to the Required Reserve Amount (an
"AUTHORIZED SHARE FAILURE"), then the Company shall immediately take all action
necessary to increase the Company's authorized shares of Common Stock to an
amount sufficient to allow the Company to reserve the Required Reserve Amount
for the Notes then outstanding. Without limiting the generality of the foregoing
sentence, as soon as practicable after the date of the occurrence of an
Authorized Share Failure, but in no event later than 60 days after the
occurrence of such Authorized Share Failure, the Company shall hold a meeting of
its stockholders for the approval of an increase in the number of authorized
shares of Common Stock. In connection with such meeting, the Company shall
provide each stockholder with a proxy statement and shall use its best efforts
to solicit its stockholders' approval of such increase in authorized shares of
Common Stock and to cause its board of directors to recommend to the
stockholders that they approve such proposal.

                  (12) HOLDER'S REDEMPTIONS.

                        (a) Mechanics. In the event that the Holder has either
sent a Redemption Notice to the Company pursuant to Section 4(b), Section 5(c),
Section 8(a) or Section 8(b), or the Holder has received an Acquiring Entity
Change of Control Redemption Notice pursuant to Section 5(d) or a Company
Optional Redemption Notice pursuant to Section 9(b), then the Holder shall
promptly after receipt of the applicable Redemption Price (and shares of Common
Stock to which the Company is required to issue and deliver pursuant to the

                                       24
<PAGE>
Company Redemption Share Election) submit this Note to the Company. The Company
shall deliver the applicable Event of Default Redemption Price to the Holder
within five Business Days after the Company's receipt of the Holder's Event of
Default Redemption Notice. If the Holder has submitted a Change of Control
Redemption Notice in accordance with Section 5(c), the Company shall deliver the
applicable Change of Control Redemption Price to the Holder concurrently with
the consummation of such Change of Control if such notice is received prior to
the consummation of such Change of Control and within five Business Days after
the Company's receipt of such notice otherwise. If the Holder has received an
Acquiring Entity Change of Control Redemption Notice and the Conditions to
Acquiring Entity Redemption are satisfied pursuant to Section 5(d), then the
Company shall deliver the applicable Acquiring Entity Change of Control
Redemption Price to the Holder concurrently with the consummation of such Change
of Control if such notice is received at least five (5) days prior to the
consummation of such Change of Control and within five Business Days after the
Company's delivery of such notice otherwise (the "ACQUIRING ENTITY CHANGE OF
CONTROL REDEMPTION DATE"). The Company shall deliver the applicable Holder
Initial Redemption Price to the Holder within five Business Days after the
Company's receipt of the Holder Initial Redemption Notice (the "INITIAL
REDEMPTION DATE"). The Company shall deliver the applicable Holder Secondary
Redemption Price to the Holder on (i) April 15, 2006, if the Holder delivers the
Holder Secondary Redemption Notice to the Company on or before April 13, 2006
and (ii) within five Business Days after the Company's receipt of the Holder
Secondary Redemption Notice if delivered after April 13, 2006 (the "SECONDARY
REDEMPTION DATE"). The Company shall deliver the Company Optional Redemption
Amount to the Holder on the fifth Business Day after delivery of the Company
Optional Redemption Notice (the "COMPANY OPTIONAL REDEMPTION DATE"). In the
event of a redemption of less than all of the Conversion Amount of this Note,
the Company shall promptly cause to be issued and delivered to the Holder a new
Note (in accordance with Section 19(d)) representing the outstanding Principal
which has not been redeemed. In the event that the Company does not pay the
Redemption Price to the Holder (or deliver any Common Stock to be issued
pursuant to a Company Redemption Share Election) within the time period
required, at any time thereafter and until the Company pays such unpaid
Redemption Price (and issues any Common Stock required pursuant to a Company
Redemption Share Election) in full, the Holder shall have the option, in lieu of
redemption, to require the Company to promptly return to the Holder all or any
portion of this Note representing the Conversion Amount that was submitted for
redemption and for which the applicable Redemption Price (or any Common Stock
required to be issued pursuant to a Company Redemption Share Election) (together
with any Late Charges thereon) has not been paid. Upon the Company's receipt of
such notice, (x) the Redemption Notice shall be null and void with respect to
such Conversion Amount, (y) the Company shall immediately return this Note, or
issue a new Note (in accordance with Section 19(d)) to the Holder representing
such Conversion Amount and (z) the Conversion Price of this Note or such new
Notes shall be adjusted to the lesser of (A) the Conversion Price as in effect
on the date on which the Redemption Notice is voided and (B) the lowest Closing
Bid Price during the period beginning on and including the date on which the
Redemption Notice is delivered to or by the Company and ending on and including
the date on which the Redemption Notice is voided. The Holder's delivery of a
notice voiding a Redemption Notice and exercise of its rights following

                                       25
<PAGE>
such notice shall not affect the Company's obligations to make any payments of
Late Charges which have accrued prior to the date of such notice with respect to
the Conversion Amount subject to such notice.

                        (b) Redemption by Other Holders. Upon the Company's
receipt of notice from any of the holders of the Other Notes or the Separate
Tranche Notes for redemption or repayment as a result of an event or occurrence
substantially similar to the events or occurrences described in Section 4(b),
Section 5(c), Section 8(a) or Section 8(b), or the delivery to the holders of
the Other Notes or the Separate Tranche Notes of an Acquiring Entity Change of
Control Redemption Notice or Company Optional Redemption Notice or similar
notice based on events or occurrences substantially similar to the events or

                        WARRANT TO PURCHASE COMMON STOCK

Warrant No.: 1
Number of Shares:______________
Date of Issuance: December 31, 2002 ("ISSUANCE DATE")

Viewpoint Corporation, a Delaware corporation (the "COMPANY"), hereby certifies
that, for Ten United States Dollars ($10.00) and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
_____________, the registered holder hereof or its permitted assigns, is
entitled, subject to the terms set forth below, to purchase from the Company, at
the Exercise Price (as defined below) then in effect, upon surrender of this
Warrant to Purchase Common Stock (including all Warrants to Purchase Common
Stock issued in exchange, transfer or replacement hereof, the "WARRANT"), at any
time or times on or after the date hereof, but not after 11:59 P.M., New York
Time, on the Expiration Date (as defined below), ______________ (_______) fully
paid nonassessable shares of Common Stock (as defined below) (the "WARRANT
SHARES"). Except as otherwise defined herein, capitalized terms in this Warrant
shall have the meanings set forth in Section 15. This Warrant is one of the
Warrants to Purchase Common Stock (the "SPA WARRANTS") issued pursuant to
Section 1 of that certain Securities Purchase Agreement, dated as of December
31, 2002 (the "INITIAL ISSUANCE DATE"), among the Company and the purchasers
(the "PURCHASERS") referred to therein (the "SECURITIES PURCHASE AGREEMENT").

         1.       EXERCISE OF WARRANT.

                  (a) Mechanics of Exercise. Subject to the terms and conditions
hereof (including, without limitation, the limitations set forth in Section
1(f)), this Warrant may be exercised by the holder hereof on any day, in whole
or in part, by (i) delivery of a written notice,
<PAGE>
in the form attached hereto as Exhibit A (the "EXERCISE NOTICE"), of such
holder's election to exercise this Warrant, (ii) (A) payment to the Company of
an amount equal to the applicable Exercise Price multiplied by the number of
Warrant Shares as to which this Warrant is being exercised (the "AGGREGATE
EXERCISE PRICE") in cash or by wire transfer of immediately available funds or
(B) by notifying the Company that this Warrant is being exercised pursuant to a
Cashless Exercise (as defined in Section 1(d)) and (iii) the surrender to the
Company, on or as soon as practicable following the date the holder of this
Warrant delivers the Exercise Notice to the Company, of this Warrant (or an
indemnification undertaking with respect to this Warrant in the case of its
loss, theft or destruction). On or before the third Business Day following the
date on which the Company has received each of the Exercise Notice, the
Aggregate Exercise Price (or notice of a Cashless Exercise) and this Warrant (or
an indemnification undertaking with respect to this Warrant in the case of its
loss, theft or destruction) (the "EXERCISE DELIVERY DOCUMENTS"), the Company
shall (X) issue and deliver to the address specified in the Exercise Notice, a
certificate, registered in the name of the holder of this Warrant or its
designee, for the number of shares of Common Stock to which the holder of this
Warrant is entitled pursuant to such exercise, or (Y) provided that the
Company's transfer agent (the "TRANSFER AGENT") is participating in The
Depository Trust Company ("DTC") Fast Automated Securities Transfer Program,
upon the request of the holder, credit such aggregate number of shares of Common
Stock to which the holder of this Warrant is entitled pursuant to such exercise
to the holder's or its designee's balance account with DTC through its Deposit
Withdrawal Agent Commission system. Upon delivery of the Exercise Notice, this
Warrant and the Aggregate Exercise Price referred to in clause (ii)(A) above or
notification to the Company of a Cashless Exercise referred to in Section 1(d),
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 as of the date of the Exercise Notice, irrespective
of the date of delivery of this Warrant as required by clause (iii) above or the
certificates evidencing such Warrant Shares. If the number of Warrant Shares
represented by this Warrant submitted for exercise pursuant to this Section 1(a)
is greater than the number of Warrant Shares being acquired upon an exercise,
then the Company shall as soon as practicable and in no event later than three
Business Days after any exercise and at its own expense, issue a new Warrant (in
accordance with Section 7(d)) representing the right to purchase the number of
Warrant Shares purchasable immediately prior to such exercise under this
Warrant, less the number of Warrant Shares with respect to which this Warrant is
exercised. No fractional shares of Common Stock are to be issued upon the
exercise of this Warrant, but rather the number of shares of Common Stock to be
issued shall be rounded up to the nearest whole number. The Company shall pay
any and all documentary stamp, transfer or similar taxes that may be payable
with respect to the issuance and delivery of Warrant Shares upon exercise of
this Warrant.

                  (b) Exercise Price. For purposes of this Warrant, "EXERCISE
PRICE" means $2.26, subject to adjustment as provided herein.

                  (c) Company's Failure to Timely Deliver Securities.

         (i) Failure to Deliver Shares. Subject to Section 1(f), if the Company
         shall fail for any reason or for no reason to issue to the holder
         within three Business Days of receipt of the Exercise Delivery
         Documents, a certificate for the number of shares of Common Stock to
         which the holder is entitled or to credit the holder's balance account
         with DTC

                                       -2-
<PAGE>
         for such number of shares of Common Stock to which the holder is
         entitled upon the holder's exercise of this Warrant, the Company shall
         pay as additional damages in cash to such holder on each day after such
         third Business Day that the issuance of such Common Stock certificate
         is not timely effected an amount equal to 1.0% 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 (B)
         the Closing Sale Price of the Common Stock on the trading day
         immediately preceding the last possible date which the Company could
         have issued such Common Stock to the holder without violating Section
         1(a).

         (ii) Failure to Deliver New Warrant. If within ten Business Days after
         the Company's receipt of the Exercise Delivery Documents, the Company
         fails to deliver a new Warrant to the holder for the number of shares
         of Common Stock to which such holder is entitled, the Company shall pay
         as additional damages in cash to such holder on each day after such
         tenth Business Day that such delivery of such new Warrant is not timely
         effected an amount equal to 1.0% of the product of (A) the number of
         shares of Common Stock represented by the portion of this Warrant which
         is not being exercised and (B) the Closing Sale Price of the Common
         Stock on the trading day immediately preceding the last possible date
         which the Company could have issued such Warrant to the holder without
         violating Section 1(a).

                  (d) Cashless Exercise. Notwithstanding anything contained
herein to the contrary, if at any time during the period commencing ten (10)
Business Days prior to the holder's delivery of an Exercise Notice and ending on
the day of delivery of the Exercise Notice, a Registration Statement (as defined
in the Registration Rights Agreement) covering the Warrant Shares that are the
subject of the Exercise Notice (the "UNAVAILABLE WARRANT SHARES") is not
available for the resale of such Unavailable Warrant Shares, the holder of this
Warrant may, in its sole discretion, exercise this Warrant in whole or in part
and, in lieu of making the cash payment otherwise contemplated to be made to the
Company upon such exercise in payment of the Aggregate Exercise Price, elect
instead to receive upon such exercise the "Net Number" of shares of Common Stock
determined according to the following formula (a "CASHLESS EXERCISE"):

         Net Number = (A x B) - (A x C)
                      -----------------
                                B
                  For purposes of the foregoing formula:

                           A= the total number of shares with respect to which
                           this Warrant is then being exercised.

                           B= the Closing Sale Price of the Common Stock (as
                           reported by Bloomberg) on the date immediately
                           preceding the date of the Exercise Notice.

                           C= the Exercise Price then in effect for the
                           applicable Warrant Shares at the time of such
                           exercise.

                                      -3-
<PAGE>
                  (e) Disputes. In the case of a dispute as to the determination
of the Exercise Price or the arithmetic calculation of the Warrant Shares, the
Company shall promptly issue to the holder the number of Warrant Shares that are
not disputed and resolve such dispute in accordance with Section 12.

                  (f)      Limitations on Exercises.

         (i) Beneficial Ownership. The Company shall not effect the exercise of
         this Warrant, and no Person (as defined below) who is a holder of this
         Warrant shall have the right to exercise this Warrant, to the extent
         that after giving effect to such exercise, such Person (together with
         such Person's affiliates) would beneficially own in excess of 4.99% of
         the shares of the Common Stock outstanding immediately after giving
         effect to such exercise. For purposes of the foregoing sentence, the
         aggregate number of shares of Common Stock beneficially owned by such
         Person and its affiliates shall include the number of shares of Common
         Stock issuable upon exercise of this Warrant with respect to which the
         determination of such sentence is being made, but shall exclude shares
         of Common Stock which would be issuable upon (i) exercise of the
         remaining, unexercised portion of this Warrant beneficially owned by
         such Person and its affiliates and (ii) exercise or conversion of the
         unexercised or unconverted portion of any other securities of the
         Company beneficially owned by such Person and its affiliates
         (including, without limitation, any convertible notes or convertible
         preferred stock or warrants) subject to a limitation on conversion or
         exercise analogous to the limitation contained herein. Except as set
         forth in the preceding sentence, for purposes of this paragraph,
         beneficial ownership shall be calculated in accordance with Section
         13(d) of the Securities Exchange Act of 1934, as amended. For purposes
         of this Warrant, in determining the number of outstanding shares of
         Common Stock a holder may rely on the number of outstanding shares of
         Common Stock as reflected in (1) the Company's most recent Form 10-Q,
         Form 10-K or other public filing with the Securities and Exchange
         Commission, as the case may be, (2) a more recent public announcement
         by the Company or (3) any other notice by the Company or its Transfer
         Agent setting forth the number of shares of Common Stock outstanding.
         For any reason at any time, upon the written or oral request of the
         holder of this Warrant, the Company shall within two Business Days
         confirm in writing to the holder of this Warrant the number of shares
         of Common Stock then outstanding. In any case, the number of
         outstanding shares of Common Stock shall be determined after giving
         effect to the conversion or exercise of securities of the Company,
         including the SPA Securities and the SPA Warrants, by the holder of
         this Warrant and its affiliates since the date as of which such number
         of outstanding shares of Common Stock was reported.

         (ii) Principal Market Regulation. The Company shall not be obligated to
         issue any shares of Common Stock upon exercise of this Warrant if the
         issuance of such shares of Common Stock would exceed that number of
         shares of Common Stock which the Company may issue upon exercise of
         this Warrant (including, as applicable, any shares of Common Stock
         issued upon conversion of or as payment of any interest under the SPA
         Securities) without breaching the Company's obligations under the rules
         or regulations of the Principal Market (the "EXCHANGE CAP"), except
         that such limitation shall not apply in the event that the Company
         obtains the approval of its shareholders as required by the

                                      -4-
<PAGE>
         applicable rules of the Principal Market for issuances of Common Stock
         in excess of such amount. Until such approval is obtained, no Purchaser
         shall be issued, upon exercise of any SPA Warrants, shares of Common
         Stock in an amount greater than the product of the Exchange Cap
         multiplied by a fraction, the numerator of which is the total number of
         shares of Common Stock underlying the SPA Warrants issued to such
         Purchaser pursuant to the Securities Purchase Agreement on the Initial
         Issuance Date and the denominator of which is the aggregate number of
         shares of Common Stock underlying all the Warrants issued to the
         Purchasers pursuant to the Securities Purchase Agreement on the Initial
         Issuance Date (with respect to each Purchaser, the "EXCHANGE CAP
         ALLOCATION"). In the event that any Purchaser shall sell or otherwise
         transfer any of such Purchaser's SPA Warrants, the transferee shall be
         allocated a pro rata portion of such Purchaser's Exchange Cap
         Allocation, and the restrictions of the prior sentence shall apply to
         such transferee with respect to the portion of the Exchange Cap
         Allocation allocated to such transferee. In the event that any holder
         of SPA Warrants shall exercise all of such holder's SPA Warrants into a
         number of shares of Common Stock which, in the aggregate, is less than
         such holder's Exchange Cap Allocation, then the difference between such
         holder's Exchange Cap Allocation and the number of shares of Common
         Stock actually issued to such holder shall be allocated to the
         respective Exchange Cap Allocations of the remaining holders of SPA
         Warrants on a pro rata basis in proportion to the shares of Common
         Stock underlying the SPA Warrants then held by each such holder. In the
         event that the Company is prohibited from issuing any Warrant Shares
         for which an Exercise Notice has been received as a result of the rules
         and regulations of the Principal Market, the Company shall pay cash in
         exchange for cancellation of such Warrant Shares, at a price per
         Warrant Share equal to the difference between the Closing Sale Price
         and the Exercise Price as of the date of the attempted exercise.

         2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The
Exercise Price and the number of Warrant Shares shall be adjusted from time to
time as follows:

                  (a) Adjustment upon Issuance of Common Stock. If and whenever
on or after the date of issuance of this Warrant the Company issues or sells, or
in accordance with this Section 2 is deemed to have issued or sold, any shares
of Common Stock (including the issuance or sale of shares of Common Stock owned
or held by or for the account of the Company, but excluding shares of Common
Stock deemed to have been issued by the Company (I) in connection with any
employee benefit plan which has been approved by the Board of Directors of the
Company, pursuant to which the Company's securities may be issued to any
employee, officer or director for services provided to the Company (an "APPROVED
STOCK PLAN"), (II) upon conversion of any SPA Securities or upon exercise of any
SPA Warrants, (III) in connection with the payment of any interest in shares of
Common Stock on any SPA Securities or (IV) in connection with any Excluded
Security) for a consideration per share less than a price (the "APPLICABLE
PRICE") equal to the Exercise Price in effect immediately prior to such issue or
sale or deemed issuance or sale (the foregoing a "DILUTIVE ISSUANCE"), then
immediately after such issue or sale or deemed issuance or sale the Exercise
Price then in effect shall be reduced to an amount equal to the product of (x)
the Exercise Price in effect immediately prior to such issue or sale or deemed
issuance or sale and (y) the quotient determined by dividing (1) the sum of the
product of the Applicable Price and the number of shares of Common Stock Deemed

                                      -5-
<PAGE>
Outstanding immediately prior to such issue or sale or deemed issuance or sale
and the consideration, if any, received by the Company upon such issue or sale
or deemed issuance or sale, by (2) the product of the Applicable Price
multiplied by the number of shares of Common Stock Deemed Outstanding
immediately after such issue or sale or deemed issuance or sale. Upon each such
adjustment of the Exercise Price hereunder, the number of Warrant Shares shall
be adjusted to the number of shares of Common Stock determined by multiplying
the Exercise Price in effect immediately prior to such adjustment by the number
of Warrant Shares acquirable upon exercise of this Warrant immediately prior to
such adjustment and dividing the product thereof by the Exercise Price resulting
from such adjustment. For purposes of determining the adjusted Exercise Price
under this Section 2(a), the following shall be applicable:

         (i) Issuance of Options. If the Company in any manner grants any
         Options and the lowest price per share for which one share of Common
         Stock is issuable upon the exercise of any such Option or upon
         conversion, exercise or exchange of any Convertible Securities issuable
         upon exercise of any such Option is less than the Applicable Price,
         then such share of Common Stock shall be deemed to be outstanding and
         to have been issued and sold by the Company at the time of the granting
         or sale of such Option for such price per share. For purposes of this
         Section 2(a)(i), the "lowest price per share for which one share of
         Common Stock is issuable upon exercise of such Options or upon
         conversion, exercise or exchange of such Convertible Securities" shall
         be equal to the sum of the lowest amounts of consideration (if any)
         received or receivable by the Company with respect to any one share of
         Common Stock upon the granting or sale of the Option, upon exercise of
         the Option and upon conversion, exercise or exchange of any Convertible
         Security issuable upon exercise of such Option. No further adjustment
         of the Exercise Price or number of Warrant Shares shall be made upon
         the actual issuance of such Common Stock or of such Convertible
         Securities upon the exercise of such Options or upon the actual
         issuance of such Common Stock upon conversion, exercise or exchange of
         such Convertible Securities.

         (ii) Issuance of Convertible Securities. If the Company in any manner
         issues or sells any Convertible Securities and the lowest price per
         share for which one share of Common Stock is issuable upon the
         conversion, exercise or exchange thereof is less than the Applicable
         Price, then such share of Common Stock shall be deemed to be
         outstanding and to have been issued and sold by the Company at the time
         of the issuance or sale of such Convertible Securities for such price
         per share. For the purposes of this Section 2(a)(ii), the "lowest price
         per share for which one share of Common Stock is issuable upon the
         conversion, exercise or exchange" shall be equal to the sum of the
         lowest amounts of consideration (if any) received or receivable by the
         Company with respect to one share of Common Stock upon the issuance or
         sale of the Convertible Security and upon conversion, exercise or
         exchange of such Convertible Security. No further adjustment of the
         Exercise Price or number of Warrant Shares shall be made upon the
         actual issuance of such Common Stock upon conversion, exercise or
         exchange of such Convertible Securities, and if any such issue or sale
         of such Convertible Securities is made upon exercise of any Options for
         which adjustment of this Warrant has been or is to be made pursuant to
         other provisions of this Section 2(a), no further adjustment of the
         Exercise Price or number of Warrant Shares shall be made by reason of
         such issue or sale.

                                      -6-
<PAGE>
         (iii) Change in Option Price or Rate of Conversion. If the purchase
         price provided for in any Options, the additional consideration, if
         any, payable upon the issue, conversion, exercise or exchange of any
         Convertible Securities, or the rate at which any Convertible Securities
         are convertible into or exercisable or exchangeable for Common Stock
         increases or decreases at any time, the Exercise Price and the number
         of Warrant Shares in effect at the time of such increase or decrease
         shall be adjusted to the Exercise Price and the number of Warrant
         Shares which would have been in effect at such time had such Options or
         Convertible Securities provided for such increased or decreased
         purchase price, additional consideration or increased or decreased
         conversion rate, as the case may be, at the time initially granted,
         issued or sold. For purposes of this Section 2(a)(iii), if the terms of
         any Option or Convertible Security that was outstanding as of the date
         of issuance of this Warrant are increased or decreased in the manner
         described in the immediately preceding sentence, then such Option or
         Convertible Security and the Common Stock deemed issuable upon
         exercise, conversion or exchange thereof shall be deemed to have been
         issued as of the date of such increase or decrease. No adjustment
         pursuant to this Section 2(a) shall be made if such adjustment would
         result in an increase of the Exercise Price then in effect or a
         decrease in the number of Warrant Shares.

         (iv) Calculation of Consideration Received. If case any Option is
         issued in connection with the issue or sale of other securities of the
         Company, together comprising one integrated transaction in which no
         specific consideration is allocated to such Options by the parties
         thereto, the Options will be deemed to have been issued for a
         consideration of $0.01. If any Common Stock, Options or Convertible
         Securities are issued or sold or deemed to have been issued or sold for
         cash, the consideration received therefor will be deemed to be the net
         amount received by the Company therefor. If any Common Stock, Options
         or Convertible Securities are issued or sold for a consideration other
         than cash, the amount of such consideration received by the Company
         will be the fair value of such consideration, except where such
         consideration consists of securities, in which case the amount of
         consideration received by the Company will be the Closing Sale Price of
         such security on the date of receipt. If any Common Stock, Options or
         Convertible Securities are issued to the owners of the non-surviving
         entity in connection with any merger in which the Company is the
         surviving entity, the amount of consideration therefor will be deemed
         to be the fair value of such portion of the net assets and business of
         the non-surviving entity as is attributable to such Common Stock,
         Options or Convertible Securities, as the case may be. The fair value
         of any consideration other than cash or securities will be determined
         in good faith by the Board of Directors of the Company. The holders of
         SPA Warrants representing at least two-thirds of the shares of Common
         Stock obtainable upon exercise of the SPA Warrants then outstanding
         shall be entitled to dispute the determination of the Board of
         Directors of the Company. If such holders and the Company are unable to
         reach agreement within 10 days after the occurrence of an event
         requiring valuation (the "VALUATION EVENT"), the fair value of such
         consideration will be determined within fifteen Business Days after the
         tenth day following the Valuation Event by an independent, reputable
         appraiser jointly selected by the Company and the holders of SPA
         Warrants representing at least two-thirds of the shares of Common Stock
         obtainable upon exercise of the SPA Warrants then outstanding. The
         determination of such appraiser shall be final and binding upon all
         parties absent manifest

                                      -7-
<PAGE>
         error and the fees and expenses of such appraiser shall be borne by the
         Company.

         (v) Record Date. If the Company takes a record of the holders of Common
         Stock for the purpose of entitling them (A) to receive a dividend or
         other distribution payable in Common Stock, Options or in Convertible
         Securities or (B) to subscribe for or purchase Common Stock, Options or
         Convertible Securities, then such record date will be deemed to be the
         date of the issue or sale of the shares of Common Stock deemed to have
         been issued or sold upon the declaration of such dividend or the making
         of such other distribution or the date of the granting of such right of
         subscription or purchase, as the case may be.

                  (b) Adjustment 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 Exercise Price in effect immediately prior to such
subdivision will be proportionately reduced and the number of Warrant Shares
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 Exercise Price in effect immediately prior to such
combination will be proportionately increased and the number of Warrant Shares
will be proportionately decreased. Any adjustment under this Section 2(b) shall
become effective at the close of business on the date the subdivision or
combination becomes effective.

                  (c) Other Events. If any event occurs of the type contemplated
by the provisions of this Section 2 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 Exercise
Price and the number of Warrant Shares so as to protect the rights of the holder
of this Warrant; provided that no such adjustment pursuant to this Section 2(c)
will increase the Exercise Price or decrease the number of Warrant Shares as
otherwise determined pursuant to this Section 2.

         3. RIGHTS UPON 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 similar transaction) (a
"DISTRIBUTION"), at any time after the issuance of this Warrant, then, in each
such case:

                  (a) any 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 Exercise Price by a fraction of which (i) the numerator shall
be the Closing Sale Price of the Common Stock 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 (ii) the denominator shall be

                                      -8-
<PAGE>
the Closing Sale Price of the Common Stock on the trading day immediately
preceding such record date; and

                  (b) the number of Warrant Shares 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 paragraph (a); provided that in the event that the Distribution is of
common stock ("OTHER 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 may elect to receive a warrant to purchase Other
Common Stock in lieu of an increase in the number of Warrant Shares, the terms
of which shall be identical to those of this Warrant, except that such warrant
shall be exercisable into the number of shares of Other Common Stock 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 aggregate exercise price equal to the product of 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 paragraph (a) and the number
of Warrant Shares calculated in accordance with the first part of this paragraph
(b).

         4.       PURCHASE RIGHTS; ORGANIC CHANGE.

                  (a) Purchase Rights. In addition to any adjustments pursuant
to Section 2 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 (without regard to any limitations on the 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.

                  (b) Organic Change. Any recapitalization, reorganization,
reclassification, consolidation, merger, sale of all or substantially all of the
Company's assets to another Person or other transaction, in each case which is
effected in such a way that holders of Common Stock are entitled to receive
securities or assets with respect to or in exchange for Common Stock is referred
to herein as an "ORGANIC CHANGE." Subject to Section 4(k) of the Securities
Purchase Agreement, 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 Person issuing
the securities or providing the assets in such Organic Change (in each case, the
"ACQUIRING ENTITY") a written agreement (in form and substance reasonably
satisfactory to the holders of SPA Warrants representing at least two-thirds of
the shares of Common Stock obtainable upon exercise of the SPA Warrants then
outstanding) to deliver to the holder of this Warrant in exchange for this
Warrant, a security of the Acquiring Entity evidenced by a written instrument
substantially similar in form and substance to this Warrant and reasonably

                                       -9-
<PAGE>
satisfactory to the holder of this Warrant (including, an adjusted 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 this Warrant
(without regard to any limitations on the exercise of this Warrant), if the
value so reflected is less than the Exercise Price in effect immediately prior
to such consolidation, merger or sale). In the event that an Acquiring Entity is
directly or indirectly controlled by a company or entity whose common stock or
similar equity interest is listed, designated or quoted on a securities exchange
or trading market, the holder of this Warrant may elect to treat such Person as
the Acquiring Entity for purposes of this Section 4(b). Prior to the
consummation of any other Organic Change, the Company shall be required to make
appropriate provision to insure that the holder of this Warrant thereafter will
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 this Warrant (without regard to any limitations
on the exercise of this Warrant including those set forth in Sections 1(f)(i)
and 1(f)(ii) of this Warrant), 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 this Warrant as of the date of
such Organic Change (without regard to any limitations on the exercise of this
Warrant including those set forth in Sections 1(f)(i) and 1(f)(ii) of this
Warrant).

         5. NONCIRCUMVENTION. The Company hereby covenants and agrees that 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, and
will at all times in good faith carry out all the provisions of this Warrant.
Without limiting the generality of the foregoing, the Company (i) will not
increase the par value of any shares of Common Stock receivable upon the
exercise of this Warrant above the Exercise Price then in effect, (ii) 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, and (iii) will, so long as any of the
SPA Warrants are outstanding, take all action necessary to reserve and keep
available out of its authorized and unissued Common Stock, solely for the
purpose of effecting the exercise of the SPA Warrants, 100% of the number of
shares of Common Stock as shall from time to time be necessary to effect the
exercise of the SPA Warrants then outstanding (without regard to any limitations
on exercise).

         6. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise
specifically provided herein, no holder, solely in such Person's capacity as a
holder, 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, solely
in such Person's capacity as a holder of this Warrant, any of the rights of a
shareholder 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 such Person
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

                                      -10-
<PAGE>
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 6, 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.

         7.       REISSUANCE OF WARRANTS.

                  (a) Transfer of Warrant. If this Warrant is to be transferred,
the holder shall surrender this Warrant to the Company, whereupon the Company
will forthwith issue and deliver upon the order of the holder of this Warrant a
new Warrant (in accordance with Section 7(d)), registered as the holder of this
Warrant may request, representing the right to purchase the number of Warrant
Shares being transferred by the Holder and, if less then the total number of
Warrant Shares then underlying this Warrant is being transferred, a new Warrant
(in accordance with Section 7(d)) to the holder of this Warrant representing the
right to purchase the number of Warrant Shares not being transferred.

                  (b) Lost, Stolen or Mutilated Warrant. Upon receipt by the
Company of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant, and, in the case of loss, theft or
destruction, of any indemnification undertaking by the holder of this Warrant to
the Company in customary form and reasonably acceptable to the Company (based,
in part, on the net worth of, or security provided by, the Holder) and, in the
case of mutilation, upon surrender and cancellation of this Warrant, the Company
shall execute and deliver to the Holder a new Warrant (in accordance with
Section 7(d)) representing the right to purchase the Warrant Shares then
underlying this Warrant.

                  (c) Warrant Exchangeable for Multiple Warrants. This Warrant
is exchangeable, upon the surrender hereof by the Holder at the principal office
of the Company, for a new Warrant or Warrants (in accordance with Section 7(d))
representing in the aggregate the right to purchase the number of Warrant Shares
then underlying this Warrant, and each such new Warrant will represent the right
to purchase such portion of such Warrant Shares as is designated by the holder
of this Warrant at the time of such surrender; provided, however, that no
Warrants for fractional shares of Common Stock shall be given.

                  (d) Issuance of New Warrants. Whenever the Company is required
to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant
(i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated
on the face of such new Warrant, the right to purchase the Warrant Shares then
underlying this Warrant (or in the case of a new Warrant being issued pursuant
to Section 7(a) or Section 7(c), the Warrant Shares designated by the holder of
this Warrant which, when added to the number of shares of Common Stock
underlying the other new Warrants issued in connection with such issuance, does
not exceed the number of Warrant Shares then underlying this Warrant), (iii)
shall have an issuance date, as indicated on the face of such new Warrant which
is the same as the Issuance Date, and (iv) shall have the same rights and
conditions as this Warrant.

         8. NOTICES. Whenever notice is required to be given under this Warrant,
unless otherwise provided herein, such notice shall be given in accordance with
Section 9(f) of the

                                      -11-
<PAGE>
Securities Purchase Agreement. The Company shall provide the holder of this
Warrant with prompt written notice of all actions taken pursuant to this
Warrant, including in reasonable detail a description of such action and the
reason therefore. Without limiting the generality of the foregoing, the Company
will give written notice to the holder of this Warrant (i) immediately upon any
adjustment of the Exercise Price, setting forth in reasonable detail, and
certifying, the calculation of such adjustment and (ii) at least fifteen 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 grants, issues or sales of any Options, Convertible Securities or
rights to purchase stock, warrants, securities or other property to holders of
Common Stock or (C) for determining rights to vote with respect to any Change of

in each case that such information shall be made known to the public prior to or
in conjunction with such notice being provided to such holder. Notwithstanding
the foregoing, Section 4(j) of the Securities Purchase Agreement shall apply to
all notices given pursuant to this Warrant.

         9. AMENDMENT AND WAIVER. Except as otherwise provided herein, the
provisions of this Warrant may be amended and the Company may take any action
herein prohibited, or omit to perform any act herein required to be performed by
it, only if the Company has obtained the written consent of the holders of SPA
Warrants representing at least two-thirds of the shares of Common Stock
obtainable upon exercise of the SPA Warrants then outstanding; provided that no
such action may increase the exercise price of any SPA Warrant or decrease the
number of shares or class of stock obtainable upon exercise of any SPA Warrant
without the written consent of the holder of this Warrant. No such amendment
shall be effective to the extent that it applies to less than all of the holders
of the SPA Warrants then outstanding.

         10. GOVERNING LAW. This Warrant shall be construed and enforced in
accordance with, and all questions concerning the construction, validity,
interpretation and performance of this Warrant shall be governed by, the
internal laws of the State of New York, without giving effect to any choice of
law or conflict of law provision or rule (whether of the State of New York or
any other jurisdictions) that would cause the application of the laws of any
jurisdictions other than the State of New York.

         11. CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be jointly
drafted by the Company and all the Purchasers and shall not be construed against
any person as the drafter hereof. The headings of this Warrant are for
convenience of reference and shall not form part of, or affect the
interpretation of, this Warrant.

         12. DISPUTE RESOLUTION. In the case of a dispute as to the
determination of the Exercise Price or the arithmetic calculation of the Warrant
Shares, the Company shall submit the disputed determinations or arithmetic
calculations via facsimile within two Business Days of receipt of the Exercise
Notice giving rise to such dispute, as the case may be, to the holder of this
Warrant. If the holder of this Warrant and the Company are unable to agree upon
such determination or calculation of the Exercise Price or the Warrant Shares
within three Business Days of such disputed determination or arithmetic
calculation being submitted to the Holder, then the Company shall, within two
Business Days submit via facsimile (a) the disputed determination of the
Exercise Price to an independent, reputable investment bank selected by the
Company and reasonably approved by the holder of this Warrant or (b) the
disputed arithmetic

                                      -12-
<PAGE>
calculation of the Warrant Shares to the Company's independent, outside
accountant. The Company shall cause the investment bank 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 ten Business Days from the
time it receives the disputed determinations or calculations. Such investment
bank's or accountant's determination or calculation, as the case may be, shall
be binding upon all parties absent demonstrable error.

         13. REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The
remedies provided in this Warrant shall be cumulative and in addition to all
other remedies available under this Warrant, the Securities Purchase Agreement,
the Pledge Agreement (as defined in the Securities Purchase Agreement), the
Control Agreement (as defined in the Pledge Agreement), the SPA Securities and
the Registration Rights Agreement, at law or in equity (including a decree of
specific performance and/or other injunctive relief), and nothing herein shall
limit the right of the holder of this Warrant right to pursue actual damages for
any failure by the Company to comply with the terms of this Warrant. The Company
acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to the holder of this Warrant and that the remedy at law for
any such breach may be inadequate. The Company therefore agrees that, in the
event of any such breach or threatened breach, the holder of this Warrant shall
be entitled, in addition to all other available remedies, to an injunction
restraining any breach, without the necessity of showing economic loss and
without any bond or other security being required.

         14. TRANSFER. This Warrant may be offered for sale, sold, transferred

required by Section 2(f) of the Securities Purchase Agreement.
