                              LEVEL 8 SYSTEMS, INC.

Registered Owner, or assigns, of this Warrant:

         1.       ISSUE. Upon tender (as defined in Section 5) to the Company,

Registered Owner, or assigns, is otherwise entitled to purchase.

         2.       NUMBER OF SHARES. The total number of shares of Common Stock

         3.       EXERCISE PRICE. The initial per share exercise price of this
Warrant, representing the price per share at which the shares of stock issuable
upon exercise of this Warrant may be purchased, is Twenty Five and One Sixteenth
Dollars ($25.0625) (the "Exercise Price").

         4.       EXERCISE PERIOD. This Warrant may be exercised from the
Closing Date (as defined in the Purchase Agreement) up to and including July
___, 2005 (the "Exercise Period"). If not exercised in compliance with Section 5
during this period, this Warrant and all rights granted under this Warrant shall
expire and lapse.

         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 effective registration
         statement under the Securities Act, delivery to the 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


                                       2
<PAGE>   3

         through its Deposit Withdrawal Agent Commission system. The time period
         for delivery described herein shall apply to the electronic
         transmittals described herein. The 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


                                       3
<PAGE>   4
         effective immediately after the record date for the determination of
         shareholders entitled to receive such rights or warrants.

                  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


                                       4
<PAGE>   5

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 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. If the Company, at any
         time while this Warrant is outstanding, takes any of the actions
         described in this Section 6, then, in order


                                       5
<PAGE>   6

to prevent dilution of the rights granted under this Warrant, the Exercise Price
will be subject to adjustment from time to time as provided in this Section 6.

                  (i)      Adjustment of Exercise Price upon Issuance of Common
         Stock. 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 other shares of
         Common Stock issued to any Holder 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 on the date hereof 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) share
         of Common Stock issuable upon conversion of the Series A Preferred
         Stock, (5) the shares of Common Stock issuable upon an Underwritten
         Offer (as defined in the Registration Rights Agreement) occurring
         before December 31, 2001, or (6) the 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) 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. 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 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 on the date hereof 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) share
         of Common Stock issuable upon conversion of the Series A Preferred
         Stock, (5) the shares of Common Stock issuable upon an Underwritten
         Offer (as defined in the Registration Rights Agreement) occurring
         before December 31, 2001, or (6) the 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) (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


                                       6
<PAGE>   7

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

                  (B)      Issuance of Convertible Securities. If at any time
         while this Warrant is outstanding the Company in any manner issues or
         sells any Convertible Securities (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 on the date
         hereof and listed in Schedule 2.1(c) of the Purchase Agreement, or the
         securities to be issued in the transactions set forth on such Schedule
         2.1(c) or any securities to be issued in an Underwritten Offering (as
         defined in the Registration Rights Agreement) before December 31, 2001
         or 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) and the price per share for which Common Stock is issuable upon
         such conversion or exchange 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


                                        7
<PAGE>   8

                  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 Average
                  Price of such security on Trading Day immediately preceding
                  the date of receipt thereof. In case 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 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. If any event occurs of the
                  type contemplated by the provisions of this Section 6(h)(i)
                  (subject to the


                                       8
<PAGE>   9

                  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; 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.

         7.       OPTIONAL REDEMPTION.

                  a.       Optional Redemption. This Warrant is redeemable in
         whole or in part at the option of the Company at any time, subject to
         the conditions herein, (the "Optional Redemption"):

                           (i)      Commencing on the First Business Day
                  immediately after the first anniversary of the Closing Date,
                  provided that the closing price of the Company's Common Stock
                  is greater than Fifty and One Eighth Dollars ($50.125) for
                  twenty (20) consecutive Trading Days and subject to the other
                  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 Affiliate of the Company
                  as of such date (other that 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
<PAGE>   10

                  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 and the Purchase 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>   11

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.       [INTENTIONALLY OMITTED.]

         10.      OFFICER'S CERTIFICATE. Whenever the number of shares
purchasable upon 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


                                       11

         14.      COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS. The Company
covenants that if any shares of Common Stock required to be reserved for
purposes of exercise of Warrants hereunder require registration with or approval
of any governmental authority under any Federal or state law, or any national
securities exchange, before such shares may be issued upon exercise, the Company
will use its best efforts to cause such shares to be duly registered or
approved, as the case may be.

         15.      FRACTIONAL SHARES. Upon any exercise hereunder, the Company
shall not be required to issue stock certificates representing fractions of
shares of the Common Stock, but may if otherwise permitted make a cash payment
in respect of any final fraction of a share based on the Per Share Market Value
at such time. If the Company elects not, or is unable, to make such a cash
payment, the Registered Owner shall be entitled to receive, in lieu of the final
fraction of a share, one whole share of Common Stock.

         16.      PAYMENT OF TAX UPON ISSUE OF TRANSFER. The issuance of
certificates for shares of the Common Stock upon exercise of the Warrants shall
be made without charge to the Registered Owners thereof for any documentary
stamp or similar taxes that may be payable in respect of the issue or delivery
of such certificate, provided that the Company shall not be required to pay any
tax that may be payable in respect of any transfer involved in the issuance and
delivery of any such certificate upon exercise in a name other than that of the
Registered Owner of such Warrant so converted and the Company shall not be
required to issue or deliver such certificates unless or until the person or
persons requesting the issuance thereof shall have paid to the Company the
amount of such tax or shall have established to the satisfaction of the Company
that such tax has been paid.

         17.      WARRANTS OWNED BY COMPANY DEEMED NOT OUTSTANDING. In
determining whether the holders of the outstanding Warrants have concurred in
any direction, consent or waiver under this Warrant, Warrants which are owned by
the Company or any other obligor on the Warrants or by 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 shall be
disregarded and deemed not to be outstanding for the purpose of any such
determination; provided that any Warrants owned by the Purchasers (as defined in
the Purchase Agreement) 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.

         18.      EFFECT OF HEADINGS; REFERENCES. The section headings herein
are for convenience only and shall not affect the construction hereof.
References herein to Sections are to Sections of this Warrant, unless otherwise
expressly provided.

         19.      NO RIGHTS AS STOCKHOLDER. This Warrant shall not entitle the
Registered Owner to any rights as a stockholder of the Company, including
without limitation, the right to vote, to receive dividends and other
distributions, or to receive notice of, or to attend, meetings of


                                       15
<PAGE>   16

stockholders or any other proceedings of the Company, unless and to the extent
exercised for shares of Common Stock in accordance with the terms hereof.

         20.      CERTAIN ACTIONS PROHIBITED. The Company will not, by amendment
of its charter or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other impairment, consistent with the tenor and purpose of
this Warrant. 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, and (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.

         21.      SHAREHOLDER RIGHTS PLAN. Notwithstanding the foregoing, in the
event that the Company shall distribute "poison pill" rights pursuant to a
"poison pill" shareholder rights plan (the "Rights"), the Company shall, in lieu
of making any adjustment pursuant to Section 6, make proper provision so that
each Registered Owner who exercises a Warrant after the record date for such
distribution and prior to the expiration or redemption of the Rights shall be
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
a number of shares of Common Stock equal to the number of shares of Common Stock
issuable upon such 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 to the benefit of the Registered Owners and its assigns, and shall be
binding upon any entity succeeding to the Company by merger or acquisition of
all or substantially all the assets of the Company. The Company may not assign
this Warrant or any rights or obligations hereunder without the prior written
consent of the Registered Owner. The Registered Owner may assign this Warrant,
in compliance with applicable law, without the prior written consent of the
Company.

         23.      GOVERNING LAW. This Warrant shall be governed by and construed
and enforced in accordance with the internal laws of the State of Delaware
without regard to the principles of conflicts of law thereof. Each party hereby
irrevocably submits to the nonexclusive jurisdiction of the state and federal
courts sitting in the City of New York, Borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of


                                       16
<PAGE>   17

any such court, that such suit, action or proceeding is improper. Each party
hereby irrevocably waives personal service of process and consents to process
being served in any such suit, action or proceeding by mailing a copy thereof to
such party at the address for such notices to it under this Warrant and agrees
that such service shall constitute good and sufficient service of process and
notice thereof. Nothing contained herein shall be deemed to limit in any way any
right to serve process in any manner permitted by law. EACH PARTY HEREBY
IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY
TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR
ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

         IN WITNESS WHEREOF, the Company has caused this Warrant to be executed
by its duly authorized officer as of the date first set forth above.
