Owner, or assigns, of this Warrant:

     1.  Issue. Upon tender (as defined in Section 5) to the Company, the
Company, within three (3) Business Days of the date thereof, shall issue to the
Registered Owner, or assigns, up to the number of shares specified in Section 2

to adjustment from time to time as set forth in Section 6. The Company shall at
all times reserve and hold available sufficient shares of Common Stock to

     4.  Exercise Period. This Warrant may be exercised from the Closing Date
(as defined in the Exchange Agreement) up to and including October 16, 2005 (the

     5.   Tender; Issuance of Certificates.

          a.   This Warrant may be exercised, in whole or in part, by (i) actual
     delivery of (a) the Exercise Price in cash, (b) a duly executed Warrant
     Exercise Form, a copy of which is attached to this Warrant as Exhibit A,
                                                                   ---------
     properly executed by the Registered Owner, or assigns, of this Warrant, and
     (c) by surrender of this Warrant, or (ii) if the resale of the Warrant
     Shares by the Registered Owner is not then registered pursuant to an

     Company of (i) the Warrant and (ii) a written notice of an election to
     effect a "Cashless Exercise" (as defined below) for the Warrant Shares
               -----------------
     specified in the Warrant Exercise Form. The Warrant Shares so purchased
     shall be deemed to be issued to the Registered Owner as of the close of
     business on the Business Day on which this Warrant shall have been
     surrendered, the completed Warrant Exercise Form shall have been delivered
     and payment shall have been made for such shares as set forth above. Unless
     otherwise directed in writing by the Company, the payment, Warrant and
     Warrant Exercise Form must be delivered to the principal office of the
     Company either in person or as set for in Section 14.

          b.   Commencing ninety (90) days from the Filing Date (as defined in
     the Registration Rights Agreement), if, and only if, at the time of
     exercise of this Warrant, the Warrant Shares are not saleable pursuant to
     an effective registration statement, then in addition to the exercise of
     all or a part of this Warrant by payment of the Exercise Price in cash as
     provided above, and in lieu of such payment, the Registered Owner shall
     have the right to effect a cashless exercise (a "Cashless Exercise"). In
                                                      -----------------
     the event of a Cashless Exercise, the Registered Owner may exercise this
     Warrant in whole or in part by surrendering this Warrant, together with a
     duly executed Warrant Exercise Form, in exchange for the number of shares
     of Common Stock equal to the product of (x) the number of shares as to
     which this Warrant is being exercised multiplied by (y) a fraction, the
     numerator of which is the Per Share Market Value of the Common Stock less
     the Exercise Price then in effect and the denominator of which is the Per
     Share Market Value (in each case adjusted for fractional shares as herein
     provided).

          c.   In lieu of physical delivery of the Warrant Shares, provided the
     Company's transfer agent is participating in the Depositary Trust Company
     ("DTC") Fast Automated Securities Transfer ("FAST") program, upon request
       ---                                        ----
     of the Registered Owner and in compliance with the provisions hereof, the
     Company shall use its best efforts to cause its transfer agent to
     electronically transmit the Warrant Shares to the Registered Owner by
     crediting the account of the Registered Owner's Prime Broker with DTC
     through its Deposit Withdrawal Agent Commission system. The time period for
     delivery described herein shall apply to the electronic transmittals
     described herein. The

                                       2
<PAGE>

     Company and its transfer agent shall be entitled to rely in good faith on
     the instructions which reasonably appear on their face to be issued on
     behalf of the Holder, and will have no liability with respect to any
     misdelivery of Warrant Shares if such instructions are followed.

          d.   Certificates for the Warrant Shares so purchased, representing
     the aggregate number of shares specified in the Warrant Exercise Form,
     shall be delivered to the Registered Owner within a reasonable time, not
     exceeding three (3) Business Days, after this Warrant shall have been so
     exercised. The certificates so delivered shall be in such denominations as
     may be reasonably requested by the Registered Owner and shall be registered
     in the name of the Registered Owner or such other name as shall be
     designated by such Registered Owner. If this Warrant shall have been
     exercised only in part, then, unless this Warrant has expired, the Company
     shall, at its expense, at the time of delivery of such certificates,
     deliver to the Registered Owner a new Warrant representing the number of
     shares with respect to which this Warrant shall not then have been
     exercised.

     6.   Adjustment of Exercise Price.

          a.   Common Stock Dividends; Common Stock Splits; Reverse Common
               -----------------------------------------------------------
     Stock Splits. If the Company, at any time while this Warrant is
     ------------
     outstanding, (a) shall pay a stock dividend on its Common Stock, (b)
     subdivide outstanding shares of Common Stock into a larger number of
     shares, (c) combine outstanding shares of Common Stock into a smaller
     number of shares or (d) issue by reclassification of shares of Common Stock
     any shares of capital stock of the Company, then the Exercise Price
     thereafter shall be determined by multiplying the Exercise Price by a
     fraction the numerator of which shall be the number of shares of Common
     Stock (excluding treasury shares, if any) outstanding before such event and
     the denominator of which shall be the number of shares of Common Stock
     outstanding after such event. Any adjustment made pursuant to this
     paragraph (6)(a) shall become effective on the effective date of any
     dividend, distribution, subdivision, combination or re-classification.

          b.   Rights; Warrants. If the Company, at any time while this Warrant
               ----------------
     is outstanding, shall issue rights or warrants to all of the holders of
     Common Stock entitling them to subscribe for or purchase shares of Common
     Stock at a price per share less than the Exercise Price and similar rights
     are not concurrently distributed to the Registered Holder, the Exercise
     Price shall thereafter be determined by multiplying the Exercise Price by a
     fraction, the denominator of which shall be the number of shares of Common
     Stock (excluding treasury shares, if any) outstanding on the date of
     issuance of such rights or warrants plus the number of additional shares of
     Common Stock offered for subscription or purchase, and the numerator of
     which shall be the number of shares of Common Stock (excluding treasury
     shares, if any) outstanding on the date of issuance of such rights or
     warrants plus the number of shares which the aggregate offering price of
     the total number of shares so offered would purchase at the Exercise Price.
     Such adjustment shall be made whenever such rights or warrants are issued,
     and shall become effective immediately after the record date for the
     determination of shareholders entitled to receive such rights or warrants.

                                       3
<PAGE>

          c.   Subscription Rights. If the Company, at any time while this
               -------------------
     Warrant is outstanding, shall distribute to all of the holders of Common
     Stock evidence of its indebtedness or assets or rights or warrants to
     subscribe for or purchase any security (excluding those referred to in
     paragraphs 6(a) and (b) above) and similar rights are not concurrently
     distributed to the Registered Owner, then in each such case the Exercise
     Price at which the Warrant shall thereafter be exercisable shall be
     determined by multiplying the Exercise Price in effect immediately prior to
     the record date fixed for determination of shareholders entitled to receive
     such distribution by a fraction, the denominator of which shall be the Per
     Share Market Value of Common Stock determined as of the record date
     mentioned above, and the numerator of which shall be such Per Share Market
     Value of the Common Stock on such record date less the then fair market
     value at such record date of the portion of such assets or evidence of
     indebtedness so distributed applicable to one outstanding share of Common
     Stock as determined by the Board of Directors in good faith; provided,
                                                                  --------
     however, that in the event of a distribution exceeding ten percent (10%)
     -------
     of the net assets of the Company, such fair market value shall be
     determined by one Appraiser selected in good faith by the Registered Owner
     of the Warrant; and provided, further, that the Company, after receipt of
                         --------  -------
     the determination by such Appraiser shall have the right to select in good
     faith an additional Appraiser meeting similar qualifications in which case
     the fair market value shall be equal to the average of the determinations
     by each such Appraiser. Such adjustment shall be made whenever any such
     distribution is made and shall become effective immediately after the
     record date mentioned above.

          d.   Rounding.  All calculations under this Section 6 shall be made to
               --------
     the nearest cent or the nearest l/l00th of a share, as the case may be.

          e.   Notice of Adjustment.  Whenever the Exercise Price is adjusted
               --------------------
     pursuant to paragraphs 6(a), (b) or (c), the Company shall promptly deliver
     to the Registered Owner a notice setting forth the Exercise Price after
     such adjustment and setting forth a brief statement of the facts requiring
     such adjustment.

          f.   Events Triggering Redemption.  The following are "Redemption
               ----------------------------                      ----------
     Events"  under this Section  6.(f):  (A) any  reclassification  of the
     ------
     Common Stock which would have a material adverse affect on the rights of
     holders of the securities into which the Warrant is exercisable, (B) any
     suspension from listing or delisting of the Common Stock such that the
     Common Stock is not listed on Nasdaq or any Subsequent Market for a period
     of ten consecutive Trading Days, or (C) a breach by the Company of its
     obligations under this Warrant, but only if such breach continues for a
     period of at least 10 Trading Days after the Company is notified by any
     Holder of such breach.

     On and after notice of the occurrence of a Redemption Event, the Holder
shall have the option to require the Company to redeem (the "Redemption Right")
                                                             ----------------
in cash and subject to the terms of payment provisions set forth in Section 5,
from funds legally available therefor at the time of such redemption, the
Holder's shares of Common Stock immediately theretofore acquirable and
receivable upon the exercise of such Holder's Warrant at a price per share equal
to the product of (i) the difference between (A) Average Price immediately
preceding the effective date, the date of the closing, date of occurrence or the
date of the announcement, as the

                                       4
<PAGE>

case may be, of the Redemption Event triggering such Redemption Right and (B)
the Exercise Price, and (ii) the number of shares of Common Stock that would
have been issued upon the exercise of the Warrant immediately prior to such
Redemption Event.

          g.   Notice of Certain Events.  If:
               ------------------------

               (i)    the Company shall declare a dividend (or any other
          distribution) on its Common Stock; or

               (ii)   the Company shall declare a special nonrecurring cash
          dividend on or a redemption of its Common Stock; or

               (iii)  the Company shall authorize the granting to the holders of
          the Common Stock rights or warrants to subscribe for or purchase any
          shares of capital stock of any class or of any rights; or

               (iv)   the approval of any shareholders of the Company shall be
          required in connection with any reclassification of the Common Stock
          of the Company, any consolidation or merger to which the Company is a
          party, any sale or transfer of all or substantially all of the assets
          of the Company, or any compulsory share exchange whereby the Common
          Stock is converted into other securities, cash or property; or

               (v)    the Company shall authorize the voluntary or involuntary
          dissolution, liquidation or winding up of the affairs of the Company;

     then the Company shall cause to be filed at each office or agency
     maintained for the purpose of exercise of this Warrant, and shall cause to
     be delivered to the Registered Owner, at least 10 Business Days prior to
     the applicable record or effective date hereinafter specified, a notice
     stating (x) the date on which a record is to be taken for the purpose of
     such dividend, distribution, redemption, rights or warrants, or if a record
     is not to be taken, the date as of which the holders of Common Stock of
     record to be entitled to such dividend, distributions, redemption, rights
     or warrants are to be determined or (y) the date on which such
     reclassification, consolidation, merger, sale, transfer or share exchange
     is expected to become effective or close, and the date as of which it is
     expected that holders of Common Stock of record shall be entitled to
     exchange their shares of Common Stock for securities, cash or other
     property deliverable upon such reclassification, consolidation, merger,
     sale, transfer or share exchange; provided, however, that the failure to
                                       --------  -------
     mail such notice or any defect therein or in the mailing thereof shall not
     affect the validity of the corporate action required to be specified in
     such notice.

          h.   Adjustment to Exercise Price.  Subject to the Issuance Cap
               ----------------------------
     exception in Section 6(j) below, if the Company, at any time while this
     Warrant is outstanding, takes any of the actions described in this Section

               (i)  Adjustment of Exercise Price upon Issuance of Common Stock.
                    ----------------------------------------------------------
          Subject to the Issuance Cap exception in Section 6(j) below, if at any
          time while this Warrant is outstanding the Company issues or sells, or
          is deemed to have issued or sold, any shares of Common Stock (other
          than (1) the Underlying Shares or shares of Common Stock deemed to
          have been issued by the Company in connection with an Approved Stock
          Plan, (2) the shares of Common Stock issuable upon the exercise of any
          options or warrants outstanding and listed in Schedule 2.1(c) of the
          Purchase Agreement, (3) the securities to be issued in the
          transactions set forth on such Schedule 2.1(c), (4) the shares of
          Common Stock issuable upon an Underwritten Offer (as defined in the
          Registration Rights Agreement) occurring before December 31, 2001, or

          consideration for an acquisition by the Company of a division, assets
          or business (or stock constituting any portion thereof) from another
          person) for a consideration per share less than the Exercise Price in
          effect immediately prior to such issuance or sale, then immediately
          after such issue or sale, the Exercise Price then in effect shall be
          reduced to an amount equal to the lesser of: (1) the Adjusted Price in
          such issuance or sale or (2) the Average Price on the date of such
          issuance or sale. For the purpose of determining the adjusted Exercise
          Price under this Section 6(h)(i), the following shall be applicable:

               (A)  Issuance of Options.  Subject to the Issuance Cap exception
                    -------------------
          in Section 6(j) below, if at any time while this Warrant is
          outstanding the Company in any manner grants any rights or options to
          subscribe for or to purchase Common Stock or any stock or other
          securities convertible into or exchangeable for Common Stock (other

          Common Stock issued or deemed to have been issued as consideration for
          an acquisition by the Company of a division, assets or business (or
          stock constituting any portion thereof) from another person) (such
          rights or options being herein called "Options" and such convertible
                                                 -------
          or exchangeable  stock or securities being herein called  "Convertible
                                                                     -----------
          Securities") and the price per share for which Common Stock is
          ----------
          issuable upon the exercise of such Options or upon conversion or
          exchange of such Convertible Securities is less than the Exercise
          Price in effect immediately prior to such grant, then the Exercise
          Price shall be adjusted to equal to the lesser of: (1) the Adjusted
          Price upon the exercise of such Options or upon the conversion or
          exchange of such Convertible Securities or (2) the Average Price on
          the date of such grant. No adjustment of the Exercise 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

                                       6
<PAGE>

          actual issuance of such Common Stock upon conversion or exchange of
          such Convertible Securities.

               (B)  Issuance of Convertible Securities.  Subject to the Issuance
                    ----------------------------------
          Cap exception in Section 6(j) below, if at any time while this Warrant
          is outstanding the Company in any manner issues or sells any
          Convertible Securities and the price per share for which Common Stock
          is issuable upon such conversion or exchange (other than the
          Underlying Shares or shares of Common Stock deemed to have been issued
          by the Company in connection with an Approved Stock Plan, shares of
          Common Stock issuable upon the exercise of any options or warrants
          outstanding and listed in Schedule 2.1(c) of the Purchase Agreement,
          shares of Common Stock issued or deemed to have been issued as
          consideration for an acquisition by the Company of a division, assets
          or business (or stock constituting any portion thereof) from another
          person) is less than the Exercise Price in effect immediately prior to
          issuance or sale, then the Exercise Price shall be adjusted to equal
          to the lesser of: (1) the Adjusted Price issuable upon the conversion
          or exchange of such Convertible Securities or (2) the Average Price on
          the date of such issuance or sale.

               (C)  Change in Option Price or Rate of Conversion.  If there is a
                    --------------------------------------------
          change at any time in (i) the purchase price provided for in any
          Options, (ii) the additional consideration, if any, payable upon the
          issuance, conversion or exchange of any Convertible Securities or
          (iii) the rate at which any Convertible Securities are convertible
          into or exchangeable for Common Stock, then the Exercise Price in
          effect at the time of such change shall be readjusted to the lesser of
          (1) the Exercise Price which would have been in effect at such time
          had such Options or Convertible Securities still outstanding 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 or (2) the Average Price on the date of such change;
          provided that no adjustment shall be made if such adjustment would
          result in an increase of the Exercise Price then in effect.

               (D)  Effect on Exercise Price of Certain Events.  For purposes of
                    ------------------------------------------
          determining the adjusted Exercise Price under this Section 6, the
          following shall be applicable:

                    (I)  Calculation of Consideration Received.  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. In case 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

               the Company will be the Average Price of such security on Trading

               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
               jointly by the Company and the registered owners of a majority of
               the Underlying Shares of Warrants then outstanding. If such
               parties are unable to reach agreement within ten (10) days after
               the occurrence of an event requiring valuation (the "Valuation
                                                                    ---------
               Event"), the fair value of such consideration will be determined
               -----
               within forty-eight (48) hours of the tenth (10th) day following
               the Valuation Event by an Appraiser selected in good faith by the
               Company and agreed upon in good faith by the holders of a
               majority of the Warrants then outstanding. The determination of
               such Appraiser shall be binding upon all parties absent manifest
               error.

                    (II)   Integrated Transactions.  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 an aggregate consideration of $.001.

                    (III)  Treasury Shares.  The  number of shares of Common
                           ---------------
               Stock outstanding at any given time does not include shares owned
               or held by or for the account of the Company, and the disposition
               of any shares so owned or held will be considered an issue or
               sale of Common Stock.

                    (IV)   Record Date.  If the Company takes a record of the
                           -----------
               holders of Common Stock for the purpose of entitling them (1) to
               receive a dividend or other distribution payable in Common Stock,
               Options or in Convertible Securities or (2) 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.

                    (V)    Certain Events.  Subject to the Issuance Cap
                           --------------

               contemplated by the provisions of this Section 6(h)(i) (subject
               to the exceptions stated therein) 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 so as to protect the rights of the Registered Owner, or
               assigns, of this Warrant;

                                       8
<PAGE>

               provided, however, that no such adjustment will increase the
               Exercise Price as otherwise determined pursuant to this Section
               6(h).

                    (VI)   "Common Stock Deemed Outstanding" means, at any
                            -------------------------------
               given time, the number of shares of Common Stock issued and
               outstanding at such time, plus the number of shares of Common
               Stock deemed to be outstanding pursuant to Sections 7.1(g)(ii)(A)
               and 7(g)(ii)(B) hereof regardless of whether the Options or
               Convertible Securities are actually exercisable at such time, but
               excluding any shares of Common Stock issuable upon exercise of
               the Warrants

     Notwithstanding the foregoing, in no event shall any provision in this
Section 6 cause the Exercise Price to be greater than the Exercise Price on the
date of issuance of this Warrant.

          i.   Adjustment of Number of Shares.  Upon each adjustment of the
               ------------------------------
     Exercise Price as a result of the calculations made in this Section 6, this
     Warrant shall thereafter evidence the right to receive, at the adjusted
     Exercise Price, that number of shares of Common Stock (calculated to the
     nearest one-hundredth) obtained by dividing (i) the product of the
     aggregate number of shares covered by this Warrant immediately prior to
     such adjustment and the Exercise Price in effect immediately prior to such
     adjustment of the Exercise Price by (ii) the Exercise Price in effect
     immediately after such adjustment of the Exercise Price.

          j.   Issuance Cap.  Notwithstanding anything in the foregoing, the
               ------------
     provisions of Section 6(h) shall not be deemed in effect until such time as
     the Company exceeds the Issuance Cap as defined in Section 7.1(l) of the
     Series B1 Certificate of Designation.

          conditions set forth herein.

               (ii)  After the Original Issue Date, if the Warrants outstanding
          represent less than 5% of the Warrant Shares to be issued upon
          exercise of the Warrants issued on the Original Issue Date remain
          unexercised, excluding from such calculation any Warrants held by an
          Affiliate of the Company as of such date (other than any Holder or
          transferees or successors or assigns thereof if such Holder is deemed
          to be an Affiliate solely by reason of its holding of Preferred Stock
          and Warrants).

                                       9

          b.   Redemption Notice.  Subject to the conditions set forth in
               -----------------
     Section 7(a), so long as (i) any Registration Statement required to be
     filed and be effective pursuant to the Registration Rights Agreement is
     then in effect and has been in effect and sales of all of the Registrable
     Securities can be made thereunder for at least twenty (20) days prior to
     the Redemption Notice Date (as defined below) and (ii) the Company has a
     sufficient number of authorized shares of Common Stock reserved for
     issuance upon full exercise of the outstanding Warrants, upon ten (10)
     Business Days' prior written notice to the Registered Owner (a "Redemption
                                                                     ----------
     Notice"),  the Warrant may be redeemed by the Company, in whole or in part,
     ------
     at a redemption price equal to $.001 per Warrant (the "Redemption Price").
                                                            ----------------

          c.   Mechanics of Redemption.  The Company shall exercise its right to
               -----------------------
     redeem by delivering its Redemption Notice by facsimile and overnight
     courier to each Registered Owner (such date that the Redemption Notice is
     given on the "Redemption Notice Date"). Such Redemption Notice shall
                   ------------------------
     indicate (A) the Redemption Price, (B) each Registered Owner's pro rata
     allocation of such maximum amount, and (C) a confirmation of the date that
     the Company shall effect the redemption (the "Redemption Date"). The
                                                   ---------------
     Redemption Date shall be not less than ten (10) Business Days and not more
     than sixty (60) calendar days after the Redemption Notice Date.
     Notwithstanding anything in this Section 7(c), the Company shall convert
     any Warrant pursuant to Section 5 if the Warrant Exercise Form for a
     Warrant submitted for exercise is (i) received by the Company, together
     with the Exercise Price in cash and the Warrant, before the Redemption
     Date, (ii) for an Exercise Price greater than or equal to the Redemption
     Price (appropriately adjusted in accordance with the terms hereof) and
     (iii) in excess of such Registered Owner's pro rata allocation of the
     maximum Redemption Price indicated in its Redemption Notice.

          d.   Payment of Redemption Price.  The Company shall pay the
               ---------------------------
     applicable Redemption Price to the Registered Owner of the Warrants being
     redeemed in cash on the Redemption Date (or, if later, the Business Day
     following the Business Day upon which the Company receives the Warrant). If
     the Company shall fail to pay the applicable Redemption Price to such
     Registered Owner on the Redemption Date, in addition to any remedy such
     Registered Owner may have under this Warrant, the Purchase Agreement and
     the Exchange Agreement, such unpaid amount shall bear interest at the rate
     of 2.0% per month until paid in full.

     8.   Nasdaq Limitation.  If on any date (the "Determination Date") (a) the
                                                   ------------------
Common Stock is listed for trading on Nasdaq, (b) the Exercise Price then in
effect is such that the aggregate number of shares of Common Stock that would
then be issuable upon exercise in full of the then outstanding Warrants as if
all such Warrants were exercised on such Determination Date (without regard to
any limitations on exercises) and as payment of interest thereon, as would equal
or exceed 20% of the number of shares of the Common Stock outstanding
immediately prior to the "Closing Date" (the "Issuable Maximum"), and (c) the
                          ------------        ----------------
Company shall not have previously obtained the vote of the shareholders of the
Company (the "Shareholder Approval"), if any, as may be required by the
              --------------------
applicable rules and regulations of Nasdaq (or any successor  entity) to approve
the issuance of shares of Common Stock in excess of the Issuable

                                       10
<PAGE>

Maximum in a private placement whereby shares of Common Stock are deemed to have
been issued at a price that is less than the greater of book value or fair
market value of the Common Stock, then with respect to the aggregate number of
Warrants then held by the Holders for which an exercise in accordance with the
Exercise Price would result in an issuance of shares of Common Stock in excess
of such Holder's pro rata allocation (as described below) of the Issuable
Maximum (the "Excess Amount"), the Company may elect to pay cash to the Holders
              -------------
in an amount equal to the product of the Average Price on the Determination Date
multiplied by the number of shares of Common Stock that would be issued upon the
exercise of the Warrants resulting in the Excess Amount (the "Prepayment
                                                              ----------
Amount").  Any such  election  by the  Company  must be made in  writing  to the
------
Holders within five (5) Trading Days after the first such Determination Date and
the payment of such Prepayment Amount applicable to such prepayment must be made
in full to the Holders with ten (10) Business Days after the date such notice is
delivered. If the Company does not deliver timely a notice of its election to
prepay under this Section or shall, if it shall have delivered such a notice,
fail to pay the Prepayment Amount hereunder within ten (10) Business Days
thereafter, then each Holder shall have the option by written notice to the
Company, to, if applicable, declare any such notice given by the Company, if
given, to be null and void and require the Company to either: (i) use its best
efforts to obtain the Shareholder Approval applicable to such issuance as soon
as is possible, but in any event not later than the 60th day after such request
unless the Company has previously used its best efforts to, but has failed to,
obtain such approval (provided, that if the Company shall fail to obtain the
Shareholder Approval during such 60-day period, the Holder may demand the cash
payment set forth in Section 8(ii) herein) or (ii) pay cash to such Holder,
within five (5) Business Days of such Holder's notice, in an amount equal to the
Prepayment Amount for such Holder's portion of the Excess Amount. The payment of
the Prepayment Amount to each Holder pursuant to this Section shall be
determined on a pro rata basis upon the number of shares of Common Stock
issuable upon the exercise of the Warrants held by such Holder on the
Determination Date which is in excess of the pro rata allocation of the Issuable
Maximum. If the Company fails to pay the Prepayment Amount in full pursuant to
this Section within five (5) Business Days after the date payable, the Company
will pay interest thereon at a rate of 20% per annum to the converting Holder,
accruing interest daily from the date of conversion until such amount, plus all
such interest thereon, if any, is paid in full. Until the Company has received
the Shareholder Approval no Holder shall be issued, upon exercise of a Warrant ,
shares of Common Stock in an amount greater than such Holder's allocated portion
of the Issuable Maximum pursuant to Section 8.

     9.   Restriction on Exercise by Either the Registered Owner or the Company.
Notwithstanding anything herein to the contrary, in no event shall any
Registered Owner have the right or be required to exercise this Warrant if as a
result of such conversion the aggregate number of shares of Common Stock
beneficially owned by such Registered Owner and its Affiliates would exceed
4.99% of the outstanding shares of the Common Stock following such exercise. The
Company shall be entitled to rely on a Notice of Exercise in the form of Exhibit
A hereto in issuing shares of Common Stock to a Registered Owner. For purposes
of this Section 9, beneficial ownership shall be calculated in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended. The provisions
of this Section 9 may be waived by a Registered Owner as to itself (and solely
as to itself) upon not less than 65 days prior written notice to the Company.

exercise shall be adjusted as required by the provisions of Section 6, the
Company shall forthwith file in the custody of its Secretary or an Assistant
Secretary at its principal office and with its stock transfer agent, if any, an
officer's certificate showing the adjusted number of shares determined as herein
provided, setting forth in reasonable detail the facts requiring such adjustment
and the manner of computing such adjustment. Each such officer's certificate
shall be signed by the chairman, president or chief financial officer of the
Company and by the secretary or any assistant secretary of the Company. Each
such officer's certificate shall be made available at all reasonable times for
inspection by any Registered Owner of the Warrants and the Company shall,
forthwith after each such adjustment, deliver a copy of such certificate to the
each of the Registered Owners.

controlling or controlled by or under direct or indirect common control with the
Company or any other obligor on the Warrants shall be disregarded and deemed not
to be outstanding for the purpose of any such determination; provided that any
Warrants owned by the Holders shall be deemed outstanding for purposes of making
such a determination. Warrants so owned which have been pledged in good faith
may be regarded as outstanding if the pledgee establishes to the satisfaction of
the Company the pledgee's right so to act with respect to such Warrants and that
the pledgee is not the Company or any other obligor upon the Warrants or any
person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company or any other obligor on the Warrants.

charter or through any reorganization, transfer of assets, consolidation,

avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant

entitled to receive upon such exercise, in addition to the shares of Common
Stock issuable upon such exercise, a number of Rights to be determined as
follows: (i) if such exercise occurs on or prior to the date for the
distribution to the holders of Rights of separate certificates evidencing such
Rights (the "Distribution Date"), the same number of Rights to which a holder of

<PAGE>

exercise at the time of such exercise would be entitled in accordance with the
terms and provisions of and applicable to the Rights; and (ii) if such exercise
occurs after the Distribution Date, the same number of Rights to which a holder
of the number of shares into which the Warrant to exercised was exercisable
immediately prior to the Distribution Date would have been entitled on the
Distribution Date in accordance with the terms and provisions of and applicable
to the Rights, and in each case subject to the terms and conditions of the
Rights.

     22.  Successors and Assigns. This Warrant shall be binding upon and inure
