      per share, (and any purchase rights issued with respect to the Common
      Stock in the future) as authorized on the date hereof, and any other

      SmallCap) on which the Common Stock may at the time be listed, or, if
      there have been no sales on any such exchange on such day, the average of
      the highest bid and lowest asked prices on all such exchanges at the end

      Value of Common Stock is being determined (or if such day is not a Trading
      Day, the Trading Day next preceding such day) and the four consecutive

      market, the Current Fair Market Value of Common Stock shall be the highest
      price per share which the Company could then obtain from a willing buyer

      daily Market Prices per share of Common Stock for the five consecutive
      Trading Days immediately prior to the date in question; provided, however,

                                      -3-
<PAGE>
      to Sections 4, 5, 6, 7 or 8 occurs during such ten consecutive Trading
      Days, the Market Price for each Trading Day prior to the "ex" date for
      such other event shall be adjusted by multiplying such Market Price by the
      same fraction by which the Purchase Price is so required to be adjusted as
      a result of such other event, (2) if the "ex" date for any event (other
      than the issuance or distribution requiring such computation) that
      requires an adjustment to the Purchase Price pursuant to Sections 4, 5, 6,
      7 or 8 occurs on or after the "ex" date for the issuance or distribution
      requiring such computation and prior to the day in question, the Market
      Price for each Trading Day on and after the "ex" date for such other event
      shall be adjusted by multiplying such Market Price by the reciprocal of
      the fraction by which the Purchase Price is so required to be adjusted as
      a result of such other event, and (3) if the "ex" date for the issuance or
      distribution requiring such computation is prior to the day in question,
      after taking into account any adjustment required pursuant to clause (1)
      or (2) of this proviso, the Market Price for each Trading Day on or after
      such "ex" date shall be adjusted by adding thereto the amount of any cash
      and the fair market value (as determined in good faith by the Board of
      Directors) of the evidences of indebtedness, shares of capital stock or
      assets being distributed applicable to one share of Common Stock as of the
      close of business on the day before such "ex" date. For purposes of this
      paragraph, the term "ex" date, (1) when used with respect to any issuance
      or distribution, means the first date on which the Common Stock trades,
      regular way, on the relevant exchange or in the relevant market from which
      the Market Price was obtained without the right to receive such issuance
      or distribution, and (2) when used with respect to any subdivision or
      combination of shares of Common Stock, means the first date on which the
      Common Stock trades, regular way, on such exchange or in such market after
      the time at which such subdivision or combination becomes effective.
      Notwithstanding the foregoing, whenever successive adjustments to the
      Purchase Price are called for pursuant to Sections 4, 5, 6, 7 or 8, such
      adjustments shall be made to the Current Market Price as may be necessary
      or appropriate to effectuate the intent of Sections 4, 5, 6, 7 and 8 and
      to avoid unjust or inequitable results as determined in good faith by the
      Board of Directors.

            "Escrow Funding Date" shall have the meaning provided in the
      Purchase Agreement.

            "Excluded Shares" shall have the meaning provided in Section 2(c).

      national securities exchange or quotation system, the average of the
      closing bid and asked prices of such security on the over-the-counter
      market on the day in question, as reported by the National Quotation
      Bureau Incorporated, or a similar generally accepted reporting service, or

surrendering this Warrant to the Company, (y) giving a subscription form in the
form of EXHIBIT 1 to this Warrant (duly executed by the Holder) to the Company,
and (z) making payment, in cash or by certified or official bank check payable
to the order of the Company, or by wire transfer of funds to the account of the
Company, in any such case, in the amount obtained by multiplying (a) the number
of shares of Common Stock designated by the Holder in the subscription form by
(b) the Purchase Price then in effect. On any partial exercise the Company will
forthwith issue and deliver to or upon the order of the Holder a new Warrant or
Warrants of like tenor, in the name of the Holder or as the Holder (upon payment

in Section 2(a), the Holder may elect to exercise this Warrant, in whole at any
time or in part from time to time, by receiving shares of Common Stock equal to

hereof, upon surrender of the subscription form annexed hereto (duly executed by
the Holder) to the Company (followed by surrender of this Warrant to the Company
within three Trading Days after surrender of such subscription form), in which
event the Company shall issue to the Holder a number of shares of Common Stock
computed using the following formula:

                                    X = Y x (A - B)
                                        -----------
                                          A


                                      -8-

            X =   the number of shares of Common Stock to be issued to the
                  Holder

            Y =   the number of shares of Common Stock as to which this Warrant
                  is to be exercised

            A =   the Current Fair Market Value of one share of Common Stock
                  calculated as of the last Trading Day immediately preceding
                  the exercise of this Warrant

            B =   the Purchase Price

            (c) 9.9% LIMITATION.

            (1) Notwithstanding anything to the contrary contained herein, the
number of shares of Common Stock that may be acquired by the Holder upon
exercise pursuant to the terms hereof at any time shall not exceed a number
that, when added to the total number of shares of Common Stock deemed
beneficially owned by the Holder (other than by virtue of the ownership of
securities or rights to acquire securities that have limitations on the Holder's
right to convert, exercise or purchase similar to the limitation set forth
herein (the "Excluded Shares"), together with all shares of Common Stock deemed
beneficially owned at such time (other than by virtue of the ownership of the
Excluded Shares) by Persons whose beneficial ownership of Common Stock would be
aggregated with the beneficial ownership by the Holder for purposes of
determining whether a group exists or for purposes of determining the Holder's
beneficial ownership (the "Aggregation Parties"), in either such case for
purposes of Section 13(d) of the 1934 Act and Regulation 13D-G thereunder
(including, without limitation, as the same is made applicable to Section 16 of
the 1934 Act and the rules promulgated thereunder), would result in beneficial
ownership by the Holder or such group of more than 9.9% of the shares of Common
Stock for purposes of Section 13(d) or Section 16 of the 1934 Act and the rules
promulgated thereunder (as the same may be modified by the Holder as provided
herein, the "Restricted Ownership Percentage"). The Holder shall have the right
at any time and from time to time to reduce its Restricted Ownership Percentage
immediately upon notice to the Company in the event and only to the extent that
Section 16 of the 1934 Act or the rules promulgated thereunder (or any successor
statute or rules) is changed to reduce the beneficial ownership percentage
threshold thereunder to a percentage less than 9.9%. If at any time the limits
in this Section 2(c) make this Warrant unexercisable in whole or in part, the
Company shall not by reason thereof be relieved of its


                                      -9-
<PAGE>
obligation to issue shares of Common Stock at any time or from time to time
thereafter but prior to the Expiration Date upon exercise of this Warrant as and
when shares of Common Stock may be issued in compliance with such restrictions.

            (2) For purposes of this Section 2(c), in determining the number of
outstanding shares of Common Stock at any time the Holder may rely on the number
of outstanding shares of Common Stock as reflected in (1) the Company's then
most recent Form 10-Q, Form 10-K or other public filing with the SEC, as the
case may be, (2) a public announcement by the Company that is later than any
such filing referred to in the preceding clause (1) or (3) any other notice by
the Company or its transfer agent setting forth the number shares of Common
Stock outstanding and knowledge the Holder may have about the number of shares
of Common Stock issued upon conversion or exercise of Common Stock Equivalents
by any Person, including the Holder, which are not reflected in the preceding
clauses (1) through (3). Upon the written request of the Holder, the Company
shall within three 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 Common Stock Equivalents, including the Notes and the Warrants,
by the Holder or its Affiliates, in each such case subsequent to, the date as of
which such number of outstanding shares of Common Stock was reported.

            3. DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE. (a) As soon as
practicable after the exercise of this Warrant and in any event within five
Trading Days thereafter, upon the terms and subject to the conditions of this
Warrant, the Company at its expense (including the payment by it of any
applicable issue or stamp taxes) will cause to be issued in the name of and

applicable transfer taxes) may direct, a certificate or certificates for the
number of fully paid and nonassessable shares of Common Stock (or Other
Securities) to which the Holder shall be entitled on such exercise, in such
denominations as may be requested by the Holder, which certificate or
certificates shall be free of restrictive and trading legends (except to the
extent permitted under Section 6.12 of the Purchase Agreement), plus, in lieu of
any fractional share to which the Holder would otherwise be entitled, cash equal
to such fraction multiplied by the then Current Fair Market Value of one full
share of Common Stock, together with any other stock or Other Securities or any
property (including cash, where applicable) to which the Holder is entitled upon
such exercise pursuant to Section 2 or otherwise. In lieu of delivering physical
certificates for the shares of Common Stock or (Other Securities) issuable upon
any exercise of this Warrant, provided the Company's transfer agent


                                      -10-

is participating in the Depository Trust Company ("DTC") Fast Automated
Securities Transfer ("FAST") program, upon request of the Holder, the Company
shall use commercially reasonable efforts to cause its transfer agent
electronically to transmit such shares of Common Stock (or Other Securities)
issuable upon conversion to the Holder (or its designee), by crediting the
account of the Holder's (or such designee's) broker with DTC through its Deposit
Withdrawal Agent Commission system (provided that the same time periods herein
as for stock certificates shall apply). The Company shall pay any taxes and
other governmental charges that may be imposed under the laws of the United
States of America or any political subdivision or taxing authority thereof or
therein in respect of the issue or delivery of shares of Common Stock (or Other
Securities) or payment of cash upon exercise of this Warrant (other than income
taxes imposed on the Holder). The Company shall not be required, however, to pay
any tax or other charge imposed in connection with any transfer involved in the
issue of any certificate for shares of Common Stock (or Other Securities)
issuable upon exercise of this Warrant or payment of cash to any Person other
than the Holder, and in case of such transfer or payment the Company shall not
be required to deliver any certificate for shares of Common Stock (or Other
Securities) upon such exercise or pay any cash until such tax or charge has been
paid or it has been established to the Company's reasonable satisfaction that no
such tax or charge is due. If the Company fails to deliver or cause to be
delivered to the Holder such shares of Common Stock (or Other Securities)
pursuant to this Section 3(a) (free of any restrictions on transfer or legends
except to the extent permitted under Section 6.12 of the Purchase Agreement) in
accordance herewith, within five Trading Days after a particular exercise of
this Warrant, then, in addition to any other liability the Company may have, the
Company shall pay to the Holder, in cash, an amount, computed at the rate of 2%
per month of the Current Fair Market Value of the shares of Common Stock (or
Other Securities) not timely delivered by the Company, for the period such
failure continues (the "Exercise Delay Payments"), with each change in the
Current Fair Market Value during such period being given effect. Upon exercise
of this Warrant as provided herein, the Company's obligation to issue and
deliver the certificates for Common Stock shall be absolute and unconditional,
irrespective of the absence of any action by the Holder to enforce the same, any
waiver or consent with respect to any provision hereof, the recovery of any
judgment against any Person or any action to enforce the same, any failure or
delay in the enforcement of any other obligation of the Company to the Holder,
or any setoff, counterclaim, recoupment, limitation or termination, or any
breach or alleged breach by the Holder or any other Person of any obligation to
the Company or any violation or alleged violation of law by the Holder or any
other Person, and irrespective of any other


                                      -11-
<PAGE>
circumstance which might otherwise limit such obligation of the Company to the
Holder in connection with such exercise.

            (b) If in any case the Company shall fail to issue and deliver or
cause to be delivered the shares of Common Stock to the Holder within five
Trading Days of a particular exercise of this Warrant, in addition to any other
liabilities the Company may have hereunder and under applicable law, (A) the
Company shall pay or reimburse the Holder on demand for all out-of-pocket
expenses, including, without limitation, reasonable fees and expenses of legal
counsel, incurred by the Holder as a result of such failure; (B) if as a result
of such failure the Holder shall suffer any direct damages or liabilities from
such failure (including, without limitation, margin interest and the cost of
purchasing securities to cover a sale (whether by the Holder or the Holder's
securities broker) or borrowing of shares of Common Stock by the Holder for
purposes of settling any trade involving a sale of shares of Common Stock made
by the Holder during the period beginning on the Issuance Date and ending on the
date the Company delivers or causes to be delivered to the Holder such shares of
Common Stock), then, in addition to any amounts payable pursuant to Section
3(a), the Company shall upon demand of the Holder pay to the Holder an amount
equal to the actual, direct, demonstrable out-of-pocket damages and liabilities
suffered by the Holder by reason thereof which the Holder documents to the
reasonable satisfaction of the Company, and (C) the Holder may by written notice
(which may be given by mail, courier, personal service or telephone line
facsimile transmission) or oral notice (promptly confirmed in writing), given at
any time prior to delivery to the Holder of the shares of Common Stock issuable
in connection with such exercise of the Holder's right, rescind such exercise
and the subscription form relating thereto, in which case the Holder shall
thereafter be entitled to exercise that portion of this Warrant as to which such
exercise is so rescinded and to exercise its other rights and remedies with
respect to such failure by the Company. Notwithstanding the foregoing the
Company shall not be liable to the Holder under clauses (A) or (B) of the
immediately preceding sentence to the extent the failure of the Company to
deliver or to cause to be delivered such shares of Common Stock results from
fire, flood, storm, earthquake, shipwreck, strike, war, acts of terrorism, crash
involving facilities of a common carrier, acts of God, or any similar event
outside the control of the Company (it being understood that the action or
failure to act of the Company's Transfer Agent shall not be deemed an event
outside the control of the Company except to the extent resulting from fire,
flood, storm, earthquake, shipwreck, strike, war, acts of terrorism, crash
involving facilities of a common carrier, acts of God, or any similar event
outside the control of such Transfer Agent or the bankruptcy, liquidation or
reorganization of such Transfer


                                      -12-
<PAGE>
Agent under any bankruptcy, insolvency or other similar law). The Holder shall
notify the Company in writing (or by telephone conversation, confirmed in
writing) as promptly as practicable following the third Trading Day after the
Holder exercises this Warrant if the Holder becomes aware that such shares of
Common Stock so issuable have not been received as provided herein, but any
failure so to give such notice shall not affect the Holder's rights under this
Warrant or otherwise.

            4. ADJUSTMENT FOR DIVIDENDS IN OTHER STOCK, PROPERTY, ETC.;
RECLASSIFICATION, ETC. In case at any time or from time to time on or after the
Escrow Funding Date, all holders of Common Stock (or Other Securities) shall
have received, or (on or after the record date fixed for the determination of
stockholders eligible to receive) shall have become entitled to receive, without
payment therefor,

            (a) other or additional stock, rights, warrants or other securities
      or property (other than cash) by way of dividend, or

            (b) any cash (excluding cash dividends payable solely out of
      earnings or earned surplus of the Company), or

            (c) other or additional stock, rights, warrants or other securities
      or property (including cash) by way of spin-off, split-up,
      reclassification, recapitalization, combination of shares or similar
      corporate rearrangement,

other than (i) additional shares of Common Stock (or Other Securities) issued as
a stock dividend or in a stock-split (adjustments in respect of which are
provided for in Section 6) and (ii) rights or warrants to subscribe for Common
Stock at less than the Current Fair Market Value (adjustments in respect of
which are provided in Section 7), then and in each such case the Holder, on the
exercise hereof as provided in Section 2, shall be entitled to receive the
amount of stock, rights, warrants and Other Securities and property (including
cash in the cases referred to in subdivisions (b) and (c) of this Section 4)
which the Holder would hold on the date of such exercise if on the date of such
action specified in the preceding clauses (a) through (c) (or the record date
therefor) the Holder had been the holder of record of the number of shares of
Common Stock called for on the face of this Warrant and had thereafter, during
the period from the date thereof to and including the date of such exercise,
retained such shares and all such other or additional stock, rights, warrants
and Other Securities and property (including cash in the case referred to in
subdivisions (b) and (c) of this Section 4) receivable by the Holder as
aforesaid during such


                                      -13-
<PAGE>
period, giving effect to all adjustments called for during such period by
Section 5.

            5. EXERCISE UPON A REORGANIZATION EVENT. In case of any
Reorganization Event the Company shall, as a condition precedent to the
consummation of the transactions constituting, or announced as, such
Reorganization Event, cause effective provisions to be made so that the Holder
shall have the right thereafter, by exercising this Warrant (in lieu of the
shares of Common Stock of the Company and Other Securities or property
purchasable and receivable upon exercise of the rights represented hereby
immediately prior to such Reorganization Event) to purchase the kind and amount
of shares of stock and Other Securities and property (including cash) receivable
upon such Reorganization Event by a holder of the number of shares of Common
Stock that might have been received upon exercise of this Warrant immediately
prior to such Reorganization Event. Any such provision shall include provisions
for adjustments in respect of such shares of stock and Other Securities and
property that shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Warrant. The provisions of this Section 5 shall
apply to successive Reorganization Events.

            6. ADJUSTMENT FOR CERTAIN EXTRAORDINARY EVENTS. If on or after the
Escrow Funding Date the Company shall (i) issue additional shares of the Common
Stock as a dividend or other distribution on outstanding Common Stock, (ii)
subdivide or reclassify its outstanding shares of Common Stock, or (iii) combine
its outstanding shares of Common Stock into a smaller number of shares of Common
Stock, then, in each such event, the Purchase Price shall, simultaneously with
the happening of such event, be adjusted by multiplying the Purchase Price in
effect immediately prior to such event by a fraction, the numerator of which
shall be the number of shares of Common Stock outstanding immediately prior to
such event and the denominator of which shall be the number of shares of Common
Stock outstanding immediately after such event, and the product so obtained
shall thereafter be the Purchase Price then in effect. The Purchase Price, as so
adjusted, shall be readjusted in the same manner upon the happening of any
successive event or events described herein in this Section 6. The Holder shall
thereafter, on the exercise hereof as provided in Section 2, be entitled to
receive that number of shares of Common Stock determined by multiplying the
number of shares of Common Stock which would be issuable on such exercise
immediately prior to such issuance, subdivision or combination, as the case may
be, by a fraction of which (i) the numerator is the Purchase Price in effect
immediately prior to such issuance and (ii) the denominator is the Purchase
Price in effect on the date of such exercise.


                                      -14-
<PAGE>
            7. ISSUANCE OF RIGHTS OR WARRANTS TO COMMON STOCKHOLDERS AT LESS
THAN CURRENT FAIR MARKET VALUE. If the Company shall on or after the Escrow
Funding Date issue rights or warrants to all holders of its outstanding shares
of Common Stock entitling them to subscribe for or purchase shares of Common
Stock at a price per share less than the Current Fair Market Value on the record
date fixed for the determination of stockholders entitled to receive such rights
or warrants, then

            (a) the Purchase Price shall be adjusted so that the same shall
      equal the price determined by multiplying the Purchase Price in effect at
      the opening of business on the day after such record date by a fraction of
      which the numerator shall be the number of shares of Common Stock
      outstanding at the close of business on such record date plus the number
      of shares which the aggregate offering price of the total number of shares
      so offered would purchase at such Current Fair Market Value, and the
      denominator shall be the number of shares of Common Stock outstanding on
      the close of business on such record date plus the total number of
      additional shares of Common Stock so offered for subscription or purchase;
      and

            (b) the number of shares of Common Stock which the Holder may
      thereafter purchase upon exercise of this Warrant at the opening of
      business on the day after such record date shall be increased to a number
      equal to the quotient obtained by dividing (x) the Aggregate Purchase
      Price in effect immediately prior to such adjustment in the Purchase Price
      pursuant to clause (a) of this Section 7 by (y) the Purchase Price in
      effect immediately after such adjustment in the Purchase Price pursuant to
      clause (a) of this Section 7.

Such adjustment shall become effective immediately after the opening of business
on the day following the record date fixed for determination of stockholders
entitled to receive such rights or warrants. To the extent that shares of Common
Stock are not delivered pursuant to such rights or warrants, upon the expiration
or termination of such rights or warrants, the Purchase Price shall be
readjusted to the Purchase Price which would then be in effect had the
adjustments made upon the issuance of such rights or warrants been made on the
basis of delivery of only the number of shares


                                      -15-
<PAGE>
of Common Stock actually delivered and the number of shares of Common Stock for
which this Warrant may thereafter be exercised shall be readjusted (subject to
proportionate adjustment for any intervening exercises of this Warrant) to the
number which would then be in effect had the adjustments made upon the issuance
of such rights or warrants been made on the basis of delivery of only the number
of shares of Common Stock actually delivered. In the event that such rights or
warrants are not so issued, the Purchase Price shall again be adjusted to be the
Purchase Price which would then be in effect if such record date had not been
fixed and the number of shares of Common Stock for which this Warrant may
thereafter be exercised shall again be adjusted (subject to proportionate
adjustment for any intervening exercises of this Warrant) to be the number which
would then be in effect if such record date had not been fixed. In determining
whether any rights or warrants entitle the Holder to subscribe for or purchase
shares of Common Stock at less than such Current Fair Market Value, and in
determining the aggregate offering price of such shares of Common Stock, there
shall be taken into account any consideration received for such rights or
warrants, the value of such consideration, if other than cash, to be determined
by the Board of Directors.

            8. ADJUSTMENTS FOR CERTAIN ISSUANCES OF NEWLY ISSUED SHARES.

            (a) In case at any time on or after the Escrow Funding Date the
      Company shall issue shares of its Common Stock or Common Stock Equivalents
      (collectively, the "Newly Issued Shares"), other than an issuance pro rata
      to all holders of its outstanding Common Stock, at a price below the
      greater of (x) the Current Fair Market Value of the Common Stock at the
      time of such issuance and (y) the Purchase Price in effect immediately
      prior to such issuance, then following such issuance of Newly Issued
      Shares the Purchase Price shall be reduced as provided in Section 8(b) and
      the number of shares of Common Stock which may be issued upon exercise of
      this Warrant shall be increased as Section 8(c).

            (b) The reduction in the Purchase Price following any such
      adjustment shall be determined by multiplying the Purchase Price
      immediately prior to such adjustment by a fraction, of which the numerator
      shall be the sum of (i) the number of shares of Common Stock outstanding
      immediately prior to the issuance of the Newly Issued Shares (calculated
      on a fully-diluted basis assuming the exercise or conversion of all
      options, warrants, purchase rights or convertible securities which are
      exercisable or convertible at the time of the issuance of the Newly Issued
      Shares) plus (ii) the number of shares of Common Stock which the aggregate
      consideration, if any, received by the Company for the number of Newly
      Issued Shares would purchase at a price equal to the greater of (x) the
      Current Fair Market Value of the Common Stock at the time of such issuance
      and (y) the Purchase Price in effect immediately prior to such issuance,
      and the denominator shall be the sum of (X) the number of


                                      -16-
<PAGE>
      shares of Common Stock outstanding immediately prior to the issuance of
      the Newly Issued Shares (calculated on a fully-diluted basis assuming the
      exercise or conversion of all options, warrants, purchase rights or
      convertible securities which are exercisable or convertible at the time of
      the issuance of the Newly Issued Shares) plus (Y) the number of Newly
      Issued Shares. The adjustment provided for in this Section 8(b) may be
      expressed as the following mathematical formula:

                                    ( O +(C / MP))   x PP
                                    ---------------
               NPP                    ( O + N )
      where,

      C     =     aggregate consideration received by the Company for the Newly
                  Issued Shares

      N     =     number of Newly Issued Shares

      O     =     number of shares of Common Stock outstanding (on a fully
                  diluted basis, as described above) immediately prior to the
                  issuance of the Newly Issued Shares

      MP    =     greater of (x) Current Fair Market Value of the Common Stock
                  at the time of issuance of the Newly Issued Shares and (y)
                  Purchase Price at the time of issuance of the Newly Issued
                  Shares

      PP    =     Purchase Price immediately prior to the issuance of the Newly
                  Issued Shares

      NPP   =     Purchase Price immediately after the issuance of the Newly
                  Issued Shares

            (c) If the Purchase Price is reduced in connection with the issuance
      of Newly Issued Shares as provided in Section 8(b), then the number of
      shares of Common Stock for which this Warrant may thereafter be exercised
      shall be increased at the time of such reduction in the Purchase Price to
      a number equal to the quotient obtained by dividing (x) the Aggregate
      Purchase Price in effect immediately prior to such issuance of Newly
      Issued Shares by (y) the Purchase Price in effect immediately after such
      issuance of Newly Issued Shares after such reduction in the Purchase Price
      pursuant to Section 8(b).

            (d) Notwithstanding the foregoing, no adjustment shall be made under
      this Section 8 by reason of:


                                      -17-
<PAGE>
                  (1) the issuance by the Company of shares of Common Stock pro
            rata to all holders of the Common Stock so long as (i) any
            adjustment required by Section 6 is made and (ii) the Company shall
            have given notice thereof to the Holder pursuant to Section 15;

                  (2) the issuance by the Company of Newly Issued Shares in an
            offering for cash for the account of the Company that is
            underwritten on a firm commitment basis and is registered with the
            SEC under the 1933 Act;

                  (3) the issuance by the Company of the Notes or the Other
            Warrants or shares of Common Stock upon conversion of the Notes or
            upon exercise of this Warrant or the Other Warrants in accordance
            with the terms hereof and thereof;

                  (4) the issuance by the Company of shares of Common Stock in
            lieu of payment of cash interest on the Notes in accordance with the
            terms thereof;

                  (5) the issuance by the Company of Newly Issued Shares upon
            grant or exercise of options for employees, directors and
            consultants under the Company's 1995 Stock Option Plan and 1997
            Stock Option Plan;

                  (6) the issuance by the Company of Newly Issued Shares to the
            lessor or vendor in any equipment lease or similar equipment
            financing transaction in which the Company or any Subsidiary obtains
            the use of equipment for its business; and

                  (7) the issuance by the Company of Newly Issued Shares upon
            conversion or exercise of Common Stock Equivalents outstanding on
            the date of the Purchase Agreement and disclosed in the Purchase
            Agreement or the SEC Filings.

            9. ADJUSTMENT IN RESPECT OF REVERSE STOCK SPLIT. If the stockholder
approval of the Reverse Stock Split contemplated by Section 6.1(b) of the
Purchase Agreement is obtained and after giving effect to the adjustment
provided for in Section 6 in respect of the Reverse Stock Split, the Purchase
Price is greater than 120% of the Current Market Price for the 6th Trading Day
after the earlier of (x) the effective date of the Reverse Stock Split and (y)
the first Trading Day on which "ex" trading of the Common Stock begins in
respect of the Reverse Stock Split, the Purchase Price shall be reduced to the
greater of (A) 120% of such Current Market Price and (B) the product of $.15
times the


                                      -18-
<PAGE>
number of shares of Common Stock outstanding immediately prior to the Reverse
Stock Split as shall have, by reason of the Reverse Stock Split, become one
share of Common Stock immediately after the Reverse Stock Split times 1.2. If
the Purchase Price is reduced in connection with the Reverse Stock Split
pursuant to this Section 9, then the number of shares of Common Stock for which
this Warrant may thereafter be exercised shall be increased at the time of such
reduction in the Purchase Price to a number equal to the quotient obtained by
dividing (x) the Aggregate Purchase Price in effect immediately prior to such
reduction in the Purchase Price by (y) the Purchase Price in effect immediately
after such reduction in the Purchase Price pursuant to this Section 9.

            10. EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE.

            (a) If any of the following events occur, namely:

            (i) any reclassification or change of the outstanding shares of
      Common Stock (other than a change in par value, or from par value to no
      par value, or from no par value to par value, or as a result of a
      subdivision or combination),

            (ii) any consolidation, merger statutory exchange or combination of
      the Company with another corporation as a result of which holders of
      Common Stock shall be entitled to receive stock, securities or other
      property or assets (including cash) with respect to or in exchange for
      such Common Stock, or

            (iii) any sale or conveyance of the properties and assets of the
      Company as, or substantially as, an entirety to any other Person as a
      result of which holders of Common Stock shall be entitled to receive
      stock, securities or other property or assets (including cash) with
      respect to or in exchange for such Common Stock,

then the Company or the successor or purchasing Person, as the case may be,
shall execute with the Holder a written agreement providing that:

            (x) this Warrant shall thereafter entitle the Holder to purchase the
      kind and amount of shares of stock and Other Securities or property or
      assets (including cash) receivable upon such reclassification, change,
      consolidation, merger, statutory exchange, combination, sale or conveyance
      by the holder of a number of shares of Common Stock issuable upon exercise
      of this Warrant (assuming, for such purposes, a sufficient number of
      authorized shares of Common Stock available to exercise this Warrant)
      immediately prior to such reclassification, change, consolidation, merger,


                                      -19-
<PAGE>
      statutory exchange, combination, sale or conveyance assuming such holder
      of Common Stock did not exercise such holder's rights of election, if any,
      as to the kind or amount of securities, cash or other property receivable
      upon such consolidation, merger, statutory exchange, combination, sale or
      conveyance (provided that, if the kind or amount of securities, cash or
      other property receivable upon such consolidation, merger, statutory
      exchange, sale or conveyance is not the same for each share of Common
      Stock in respect of which such rights of election shall not have been
      exercised ("non-electing share"), then for the purposes of this Section 10
      the kind and amount of securities, cash or other property receivable upon
      such consolidation, merger, statutory exchange, sale or conveyance for
      each non-electing share shall be deemed to be the kind and amount so
      receivable per share by a plurality of the non-electing shares),

            (y) in the case of any such successor or purchasing Person, upon
      such consolidation, merger, statutory exchange, combination, sale or
      conveyance such successor or purchasing Person shall be jointly and
      severally liable with the Company for the performance of all of the
      Company's obligations under this Warrant, the Purchase Agreement and the
      Registration Rights Agreement and

            (z) if registration or qualification is required under the 1933 Act
      or applicable state law for the public resale by the Holder of such shares
      of stock and Other Securities so issuable upon exercise of this Warrant,
      such registration or qualification shall be completed prior to such
      reclassification, change, consolidation, merger, statutory exchange,
      combination or sale.

Such written agreement shall provide for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this
Warrant. If, in the case of any such reclassification, change, consolidation,
merger, statutory exchange, combination, sale or conveyance, the stock or other
securities or other property or assets receivable thereupon by a holder of
shares of Common Stock includes shares of stock, other securities, other
property or assets of a Person other than the Company or any such successor or
purchasing Person, as the case may be, in such reclassification, change,
consolidation, merger, statutory exchange, combination, sale or conveyance, then
such written agreement shall also be executed by such other Person and shall
contain such additional provisions to protect the interests of the Holder as the
Board of Directors shall reasonably consider necessary by reason of the
foregoing.


                                      -20-
<PAGE>
            (b) The above provisions of this Section 10 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

            (c) If this Section 10 applies to any event or occurrence, Section 5
shall not apply.

            11. TAX ADJUSTMENTS. The Company may make such reductions in the
Purchase Price, in addition to those required by Sections 4, 5, 6, 7, 8 and 9as
the Board of Directors considers to be advisable to avoid or diminish any income
tax to holders of Common Stock or rights to purchase Common Stock resulting from
any dividend or distribution of stock (or rights to acquire stock) or from any
event treated as such for income tax purposes.

            12. MINIMUM ADJUSTMENT. (a) No adjustment in the Purchase Price (and
no related adjustment in the number of shares of Common Stock which may
thereafter be purchased upon exercise of this Warrant) shall be required unless
such adjustment would require an increase or decrease of at least 1% in the
Purchase Price; provided, however, that any adjustments which by reason of this
Section 12 are not required to be made shall be carried forward and taken into
account in any subsequent adjustment. All such calculations under this Warrant
shall be made by the Company and shall be made to the nearest cent or to the
nearest one hundredth of a share, as the case may be.

            (b) No adjustment need be made for a change in the par value of the
Common Stock or from par value to no par value or from no par value to par
value.

            13. NOTICE OF ADJUSTMENTS. Whenever the Purchase Price is adjusted
as herein provided, the Company shall promptly, but in no event later than five
Trading Days thereafter, give a notice to the Holder setting forth the Purchase
