              EXPIRES (MONTH DATE, YEAR)(5yrs-1day from Issue Date)

         FOR VALUE RECEIVED, subject to the provisions hereinafter set forth,
the undersigned, Intraco Systems, Inc., a Nevada corporation (together with its
successors and assigns, the "Issuer"), hereby certifies that (WARRANT HOLDER) or
its registered assigns is entitled to subscribe for and purchase, during the
period specified in this Warrant, up to XX,XXX shares (subject to adjustment as
hereinafter provided) of the duly authorized, validly issued, fully paid and
non-assessable Common Stock of the Issuer, at an exercise price per share equal
to the Warrant Price then in effect, subject, however, to the provisions and
upon the terms and conditions hereinafter set forth. Capitalized terms used in
this Warrant and not otherwise defined herein shall have the respective meanings
specified in Section 8 hereof.

         1.  TERM. The right to subscribe for and purchase shares of Warrant
Stock represented hereby shall commence on the date of issuance of this Warrant
and shall expire at 00:00 AM/PM, "EASTERN" TIME, on (MONTH DATE, YEAR)(5yrs-1day
from Issue Date) (such period being the "Term").

         2.  METHOD OF EXERCISE PAYMENT: ISSUANCE OF NEW WARRANT: TRANSFER AND
EXCHANGE.

         (a) TIME OF EXERCISE. The purchase rights represented by this Warrant
may be exercised in whole or in part at any time and from time to time during
the Term.
<PAGE>

         (b) METHOD OF EXERCISE. The Holder hereof may exercise this Warrant, in
whole or in part, by the surrender of this Warrant (with the exercise form
attached hereto duly executed) at the principal office of the Issuer, and by the
payment to the Issuer of an amount of consideration therefor equal to the
Warrant Price in effect on the date of such exercise multiplied by the number of
shares of Warrant Stock with respect to which this Warrant is then being
exercised, payable at such Holder's election (i) by certified or official bank
check or (ii) by surrender to the Issuer for cancellation of a portion of this
Warrant representing that number of unissued shares of Warrant Stock which is
equal to the quotient obtained by dividing (A) the product obtained by
multiplying the Warrant Price by the number of shares of Warrant Stock being
purchased upon such exercise by (B) the difference obtained by subtracting the
Warrant Price from the Per Share Market Value as of the date of such exercise,
or (iii) by a combination of the foregoing methods of payment selected by the
Holder of this Warrant. In any case where the consideration payable upon such
exercise is being paid in whole or in part pursuant to the provisions of clause
(ii) of this subsection (b), such exercise shall be accompanied by written
notice from the Holder of this Warrant specifying the manner of payment thereof
and containing a calculation showing the number of shares of Warrant Stock with
respect to which rights are being surrendered thereunder and the net number of
shares to be issued after giving effect to such surrender.

         (c) ISSUANCE OF STOCK CERTIFICATES. In the event of any exercise of the
rights represented by this Warrant in accordance with and subject to the terms
and conditions hereof, (i) certificates for the shares of Warrant Stock so
purchased shall be dated the date of such exercise and delivered to the Holder
hereof within a reasonable time, not exceeding three (3) Trading Days after such
exercise, and the Holder hereof shall be deemed for all purposes to be the
Holder of the shares of Warrant Stock so purchased as of the date of such
exercise, and (ii) unless this Warrant has expired, a new Warrant representing
the number of shares of Warrant Stock, if any, with respect to which this
Warrant shall not then have been exercised (less any amount thereof which shall
have been canceled in payment or partial payment of the Warrant Price as
hereinabove provided) shall also be issued to the Holder hereof at the Issuer's
expense within such time.

         (d) TRANSFERABILITY OF WARRANT. Subject to Section 2(e), this Warrant
may be transferred by a Holder without the consent of the Company. If
transferred pursuant to this paragraph and subject to the provisions of
subsection (e) of this Section 2, this Warrant may be transferred on the books
of the Issuer by the Holder hereof in person or by duly authorized attorney,
upon surrender of this Warrant at the principal office of the Issuer, properly
endorsed (by the Holder executing an assignment in the form attached hereto) and
upon payment of any necessary transfer tax or other governmental charge imposed
upon such transfer. This Warrant is exchangeable at the principal office of the
Issuer for Warrants for the purchase of the same aggregate number of shares of
Warrant Stock, each new Warrant to represent the right to purchase such number
of shares of Warrant Stock as the Holder hereof shall designate at the time of
such exchange. All Warrants issued on transfers or exchanges shall be dated the
Original Issue Date and shall be identical with this Warrant except as to the
number of shares of Warrant Stock issuable pursuant hereto.

         (e) COMPLIANCE WITH SECURITIES LAWS.

             (i)    The Holder of this Warrant, by acceptance hereof,
         acknowledges that this Warrant or the shares of Warrant Stock to be
         issued upon exercise hereof are being acquired solely for the Holder's
         own account and not as a nominee for any other party, and for
         investment, and that the Holder will not offer, sell or otherwise
         dispose of this Warrant or any shares of Warrant Stock to be issued
         upon exercise hereof except pursuant to an effective registration
         statement, or an exemption from registration, under the Securities Act
         and any applicable state securities laws.

             (ii)   Except as provided in paragraph (iii) below, this Warrant
         and all certificates representing shares of Warrant Stock issued upon
         exercise hereof shall be stamped or imprinted with a legend in
         substantially the following form:

                    THIS WARRANT AND THE SHARES OF COMMON STOCK
             ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN
             REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
             AMENDED (THE "SECURITIES ACT"), OR ANY STATE
             SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR
             OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE
             SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES
             LAWS OR INTRACO SYSTEMS, INC. SHALL HAVE RECEIVED AN
             OPINION, IN FORM, SCOPE AND SUBSTANCE REASONABLY
             ACCEPTABLE TO THE COMPANY, OF COUNSEL, WHO IS
             REASONABLY ACCEPTABLE TO THE COMPANY, THAT
             REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES
             ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE
             SECURITIES LAWS IS NOT REQUIRED.

             (iii)  The restrictions imposed by this subsection (e) upon the
         transfer of this Warrant or the shares of Warrant Stock to be purchased
         upon exercise hereof shall terminate (A) when such securities shall
         have been resold pursuant to an effective registration statement under
         the Securities Act, (B) upon the Issuer's receipt of an opinion of
         counsel, in form and substance reasonably satisfactory to the Issuer,
         addressed to the Issuer to the effect that such restrictions are no
         longer required to ensure compliance with the Securities Act and state
         securities laws or (C) upon the Issuer's receipt of other evidence
         reasonably satisfactory to the Issuer that such registration and
         qualification under the Securities Act and state securities laws are
         not required. Whenever such restrictions shall cease and terminate as
         to any such securities, the Holder thereof shall be entitled to receive
         from the Issuer (or its transfer agent and registrar), without expense
         (other than applicable transfer taxes, if any), new Warrants (or, in
         the case of shares of Warrant Stock, new stock certificates) of like
         tenor not bearing the applicable legend required by paragraph (ii)
         above relating to the Securities Act and state securities laws.

         (f) CONTINUING RIGHTS OF HOLDER. The Issuer will, at the time of or at
any time after each exercise of this Warrant, upon the request of the Holder
hereof, acknowledge in writing the extent, if any, of its continuing obligation

                                       3
<PAGE>

to afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
PROVIDED that if any such Holder shall fail to make any such request, the
failure shall not affect the continuing obligation of the Issuer to afford such
rights to such Holder.

         3.  STOCK FULLY PAID: RESERVATION AND LISTING OF SHARES: COVENANTS.

         (a) STOCK FULLY PAID. The Issuer represents, warrants, covenants and
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise hereunder will, upon issuance, be duly authorized,
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges created by or through Issuer. The Issuer further covenants and agrees
that during the period within which this Warrant may be exercised, the Issuer
will at all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

         (b) RESERVATION. If any shares of Common Stock required to be reserved
for issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

         (c) COVENANTS. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will (i) not permit the par value, if any, of its
Common Stock to exceed the then effective Warrant Price, (ii) not amend or
modify any provision of the Certificate of Incorporation or by-laws of the
Issuer in any manner that would adversely affect in any way the powers,
preferences or relative participating, optional or other special rights of the
Common Stock or which would adversely affect the rights of the Holders of the
Warrants, (iii) take all such action as may be reasonably necessary in order
that the Issuer may validly and legally issue fully paid and nonassessable
shares of Common Stock, free and clear of any liens, claims, encumbrances and
restrictions (other than as provided herein) upon the exercise of this Warrant,
and (iv) use its best efforts to obtain all such authorizations, exemptions or
consents from any public regulatory body having jurisdiction thereof as may be
reasonably necessary to enable the Issuer to perform its obligations under this
Warrant.

                                       4
<PAGE>

         (d) LOSS, THEFT, DESTRUCTION OF WARRANTS. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

         (e) RIGHTS AND OBLIGATIONS UNDER THE REGISTRATION RIGHTS AGREEMENT. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holders listed on the signature pages thereof (as amended from
time to time, the "Registration Rights Agreement"). The Issuer shall keep or
cause to be kept a copy of the Registration Rights Agreement, and any amendments
thereto, at its chief executive office and shall furnish, without charge, copies
thereof to the Holder upon request.

         4.  ADJUSTMENT OF WARRANT PRICE AND WARRANT SHARE NUMBER. The number
and kind of Securities purchasable upon the exercise of this Warrant and the
Warrant Price shall be subject to adjustment from time to time upon the
happening of certain events as follows:

         (a) RECAPITALIZATION, REORGANIZATION, RECLASSIFICATION, CONSOLIDATION,
MERGER OR SALE.

             (i)    In case the Issuer after the Original Issue Date shall do
         any of the following (each, a "Triggering Event"): (a) consolidate with
         or merge into any other Person and the Issuer shall not be the
         continuing or surviving corporation of such consolidation or merger, or
         (b) permit any other Person to consolidate with or merge into the
         Issuer and the Issuer shall be the continuing or surviving Person but,
         in connection with such consolidation or merger, any Capital Stock of
         the Issuer shall be changed into or exchanged for Securities of any
         other Person or cash or any other property, or (c) transfer all or
         substantially all of its properties or assets to any other Person, or
         (d) effect a capital reorganization or reclassification of its Capital
         Stock, then, and in the case of each such Triggering Event, proper
         provision shall be made so that, upon the basis and the terms and in
         the manner provided in this Warrant, the Holder of this Warrant shall
         be entitled (x) upon the exercise hereof at any time after the
         consummation of such Triggering Event, to the extent this Warrant is
         not exercised prior to such Triggering Event, to receive at the Warrant
         Price in effect at the time immediately prior to the consummation of
         such Triggering Event in lieu of the Common Stock issuable upon such
         exercise of this Warrant prior to such Triggering Event, the
         Securities, cash and property to which such Holder would have been
         entitled upon the consummation of such Triggering Event if such Holder
         had exercised the rights represented by this Warrant immediately prior
         thereto, subject to adjustments (subsequent to such corporate action)
         as nearly equivalent as possible to the adjustments provided for in
         Section 4 hereof or (y) to sell this Warrant (or, at such Holder's
         election, a portion hereof) concurrently with the Triggering Event to
         the Person continuing after or surviving such Triggering Event, or to
         the Issuer (if Issuer is the continuing or surviving Person) at a sales
         price equal to the amount of cash, property and/or Securities to which

                                       5
<PAGE>

         a holder of the number of shares of Common Stock which would otherwise
         have been delivered upon the exercise of this Warrant would have been
         entitled upon the effective date or closing of any such Triggering
         Event (the "Event Consideration"), less the amount or portion of such
         Event Consideration having a fair value equal to the aggregate Warrant
         Price applicable to this Warrant or the portion hereof so sold.

             (ii)   Notwithstanding anything contained in this Warrant to the
         contrary, the Issuer will not effect any Triggering Event unless, prior
         to the consummation thereof, each Person (other than the Issuer) which
         may be required to deliver any Securities, cash or property upon the
         exercise of this Warrant as provided herein shall assume, by written
         instrument delivered to, and reasonably satisfactory to, the Holder of
         this Warrant, (A) the obligations of the Issuer under this Warrant (and
         if the Issuer shall survive the consummation of such Triggering Event,
         such assumption shall be in addition to, and shall not release the
         Issuer from, any continuing obligations of the Issuer under this
         Warrant) and (B) the obligation to deliver to such Holder such shares
         of Securities, cash or property as, in accordance with the foregoing
         provisions of this subsection (a), such Holder shall be entitled to
         receive, and such Person shall have similarly delivered to such Holder
         an opinion of counsel for such Person, which counsel shall be
         reasonably satisfactory to such Holder, stating that this Warrant shall
         thereafter continue in full force and effect and the terms hereof
         (including, without limitation, all of the provisions of this
         subsection (a)) shall be applicable to the Securities, cash or property
         which such Person may be required to deliver upon any exercise of this
         Warrant or the exercise of any rights pursuant hereto.

             (iii)  If with respect to any Triggering Event, the Holder of this
         Warrant has exercised its right as provided in clause (y) of
         subparagraph (i) of this subsection (a) to sell this Warrant or a
         portion thereof, the Issuer agrees that as a condition to the
         consummation of any such Triggering Event the Issuer shall secure such
         right of Holder to sell this Warrant to the Person continuing after or
         surviving such Triggering Event and the Issuer shall not effect any
         such Triggering Event unless upon or prior to the consummation thereof
         the amounts of cash, property and/or Securities required under such
         clause (y) are delivered to the Holder of this Warrant. The obligation
         of the Issuer to secure such right of the Holder to sell this Warrant
         shall be subject to such Holder's cooperation with the Issuer,
         including, without limitation, the giving of customary representations
         and warranties to the purchaser in connection with any such sale. Prior
         notice of any Triggering Event shall be given to the Holder of this
         Warrant in accordance with Section 12 hereof.

         (b) SUBDIVISION OR COMBINATION OF SHARES. If the Issuer, at any time
while this Warrant is outstanding, shall subdivide or combine any shares of
Common Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of Holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a
result of such subdivision, or (ii) in the case of a combination of shares, the
Warrant Price shall be proportionately increased (as at the effective date of
such combination or, if the Issuer shall take a record of Holders of its Common
Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

                                       6
<PAGE>

         (c) CERTAIN DIVIDENDS AND DISTRIBUTIONS. If the Issuer, at any time
while this Warrant is outstanding, shall:

             (i)    STOCK DIVIDENDS. Pay a dividend in, or make any other
         distribution to its stockholders (without consideration therefor) of,
         shares of Common Stock, the Warrant Price shall be adjusted, as at the
         date the Issuer shall take a record of the Holders of the Issuer's
         Capital Stock for the purpose of receiving such dividend or other
         distribution (or if no such record is taken, as at the date of such
         payment or other distribution), to that price determined by multiplying
         the Warrant Price in effect immediately prior to such record date (or
         if no such record is taken, then immediately prior to such payment or
         other distribution), by a fraction (1) the numerator of which shall be
         the total number of shares of Common Stock outstanding immediately
         prior to such dividend or distribution, and (2) the denominator of
         which shall be the total number of shares of Common Stock outstanding
         immediately after such dividend or distribution (plus in the event that
         the Issuer paid cash for fractional shares, the number of additional
         shares which would have been outstanding had the Issuer issued
         fractional shares in connection with said dividends); or

             (ii)   OTHER DIVIDENDS. Pay a dividend on, or make any distribution
         of its assets upon or with respect to (including, but not limited to, a
         distribution of its property as a dividend in liquidation or partial
         liquidation or by way of return of capital), the Common Stock (other
         than as described in clause (i) of this subsection (c)), or in the
         event that the Company shall offer options or rights to subscribe for
         shares of Common Stock, or issue any Common Stock Equivalents, to all
         of its holders of Common Stock, then on the record date for such
         payment, distribution or offer or, in the absence of a record date, on
         the date of such payment, distribution or offer, the Holder shall
         receive what the Holder would have received had it exercised this
         Warrant in full immediately prior to the record date of such payment,
         distribution or offer or, in the absence of a record date, immediately
         prior to the date of such payment, distribution or offer.

         (d) ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK. If the Issuer, at
any time while this Warrant is outstanding, shall issue any Additional Shares of
Common Stock (otherwise than as provided in the foregoing subsections (a)
through (c) of this Section 4), at a price per share less than the Warrant Price
then in effect or less than the Per Share Price or without consideration, then
the Warrant Price upon each such issuance shall be adjusted to that price
(rounded to the nearest cent) determined by multiplying the Warrant Price then
in effect by a fraction:

             (i)    the numerator of which shall be equal to the sum of (A) the
         number of shares of Common Stock outstanding immediately prior to the
         issuance of such Additional Shares of Common Stock PLUS (B) the number
         of shares of Common Stock (rounded to the nearest whole share) which
         the aggregate consideration for the total number of such Additional
         Shares of Common Stock so issued would purchase at a price per share
         equal to the greater of the Per Share Price and the Warrant Price then
         in effect, and

                                       7
<PAGE>

             (ii)   the denominator of which shall be equal to the number of
         shares of Common Stock outstanding immediately after the issuance of
         such Additional Shares of Common Stock.

The provisions of this subsection (d) shall not apply under any of the
circumstances for which an adjustment is provided in subsections (a), (b) or (c)
of this Section 4. No adjustment of the Warrant Price shall be made under this
subsection (d) upon the issuance of any Additional Shares of Common Stock which
are issued pursuant to any Common Stock Equivalent if upon the issuance of such
Common Stock Equivalent (x) any adjustment shall have been made pursuant to
subsection (e) of this Section 4 or (Y) no adjustment was required pursuant to
subsection (e) of this Section 4. No adjustment of the Warrant Price shall be
made under this subsection (d) in an amount less than $.01 per share, but any
such lesser adjustment shall be carried forward and shall be made at the time
and together with the next subsequent adjustment, if any, which together with
any adjustments so carried forward shall amount to $.01 per share or more,
provided that upon any adjustment of the Warrant Price as a result of any
dividend or distribution payable in Common Stock or Convertible Securities or
the reclassification, subdivision or combination of Common Stock into a greater
or smaller number of shares, the foregoing figure of $.01 per share (or such
figure as last adjusted) shall be adjusted (to the nearest one-half cent) in
proportion to the adjustment in the Warrant Price.

         (e) ISSUANCE OF COMMON STOCK EQUIVALENTS. If the Issuer, at any time
while this Warrant is outstanding, shall issue any Common Stock Equivalent and
the price per share for which Additional Shares of Common Stock may be issuable
thereafter pursuant to such Common Stock Equivalent shall be less than the
Warrant Price then in effect or less than the Per Share Price, or if, after any
such issuance of Common Stock Equivalents, the price per share for which
Additional Shares of Common Stock may be issuable thereafter is amended or
adjusted, and such price as so amended shall be less than the Warrant Price or
less than the Per Share Price, then the Warrant Price upon each such issuance or
amendment shall be adjusted as provided in the first sentence of subsection (d)
of this Section 4 on the basis that (1) the maximum number of Additional Shares
of Common Stock issuable pursuant to all such Common Stock Equivalents shall be
deemed to have been issued (whether or not such Common Stock Equivalents are
actually then exercisable, convertible or exchangeable in whole or in part) as
of the earlier of (A) the date on which the Issuer shall enter into a firm
contract for the issuance of such Common Stock Equivalent, or (B) the date of
actual issuance of such Common Stock Equivalent, and (2) the aggregate
consideration for such maximum number of Additional Shares of Common Stock shall
be deemed to be the minimum consideration received or receivable by the Issuer

             (i)    COMPUTATION OF CONSIDERATION. The consideration received by
         the Issuer shall be deemed to be the following: to the extent that any
         Additional Shares of Common Stock or any Common Stock Equivalents shall
         be issued for a cash consideration, the consideration received by the
         Issuer therefor, or if such Additional Shares of Common Stock or Common
         Stock Equivalents are offered by the Issuer for subscription, the
         subscription price, or, if such Additional Shares of Common Stock or
         Common Stock Equivalents are sold to underwriters or dealers for public
         offering, the public offering price, in any such case excluding any
         amounts paid or receivable for accrued interest or accrued dividends
         and without deduction of any compensation, discounts, commissions, or
         expenses paid or incurred by the Issuer for or in connection with the
         underwriting thereof or otherwise in connection with the issue thereof;
         to the extent that such issuance shall be for a consideration other
         than cash, then, except as herein otherwise expressly provided, the
         fair market value of such consideration at the, time of such issuance
         as determined in good faith by the Board. The consideration for any
         Additional Shares of Common Stock issuable pursuant to any Common Stock
         Equivalents shall be the consideration received by the Issuer for
         issuing such Common Stock Equivalents, plus the additional
         consideration payable to the Issuer upon the exercise, conversion or
         exchange of such Common Stock Equivalents. In case of the issuance at
         any time of any Additional Shares of Common Stock or Common Stock
         Equivalents in payment or satisfaction of any dividend upon any class
         of Capital Stock of the Issuer other than Common Stock, the Issuer
         shall be deemed to have received for such Additional Shares of Common
         Stock or Common Stock Equivalents a consideration equal to the amount
         of such dividend so paid or satisfied. In any case in which the
         consideration to be received or paid shall be other than cash, the
         Board shall notify the Holder of this Warrant of its determination of
         the fair market value of such consideration prior to payment or
         accepting receipt thereof. If, within thirty (30) days after receipt of
         said notice, the Majority Holders shall notify the Board in writing of
         their objection to such determination, a determination of the fair
         market value of such consideration shall be made by an Independent
         Appraiser selected by the Majority Holders with the approval of the
         Board (which approval shall not be unreasonably withheld), whose fees
         and expenses shall be paid by the Issuer.

             (ii)   READJUSTMENT OF WARRANT PRICE. Upon the expiration or
         termination of the right to convert, exchange or exercise any Common
         Stock Equivalent the issuance of which effected an adjustment in the
         Warrant Price, if such Common Stock Equivalent shall not have been
         converted, exercised or exchanged in its entirety, the number of shares
         of Common Stock deemed to be issued and outstanding by reason of the
         fact that they were issuable upon conversion, exchange or exercise of
         any such Common Stock Equivalent shall no longer be computed as set
         forth above, and the Warrant Price shall forthwith be readjusted and
         thereafter be the price which it would have been (but reflecting any
         other adjustments in the Warrant Price made pursuant to the provisions
         of this Section 4 after the issuance of such Common Stock Equivalent)
         had the adjustment of the Warrant Price been made in accordance with
         the issuance or sale of the number of Additional Shares of Common Stock
         actually issued upon conversion, exchange or issuance of such Common
         Stock Equivalent and thereupon only the number of Additional Shares of
         Common Stock actually so issued shall be deemed to have been issued and
         only the consideration actually received by the Issuer (computed as in
         clause (i) of this subsection (f)) shall be deemed to have been
         received by the Issuer.

                                       9
<PAGE>

             (iii)  OUTSTANDING COMMON STOCK. The number of shares of Common
         Stock at any time outstanding shall (A) not include any shares thereof
         then directly or indirectly owned or held by or for the account of the
         Issuer or any of its Subsidiaries, and (B) be deemed to include all
         shares of Common Stock then issuable upon conversion, exercise or
         exchange of any then outstanding Common Stock Equivalents or any other
         evidences of Indebtedness, shares of Capital Stock or other Securities
         which are or may be at any time convertible into or exchangeable for
         shares of Common Stock or Other Common Stock.

         (g) OTHER ACTION AFFECTING COMMON STOCK. In case after the Original
Issue Date the Issuer shall take any action affecting its Common Stock, other
than an action described in any of the foregoing subsections (a) through (f) of
this Section 4, inclusive, and the failure to make any adjustment would not
fairly protect the purchase rights represented by this Warrant in accordance
with the essential intent and principle of this Section 4, then the Warrant
Price shall be adjusted in such manner and at such time as the Board may in good
faith determine to be equitable in the circumstances.

         (h) ADJUSTMENT OF WARRANT SHARE NUMBER. Upon each adjustment in the
Warrant Price pursuant to any of the foregoing provisions of this Section 4, the
Warrant Share Number shall be adjusted, to the nearest one hundredth of a whole
share, to the product obtained by multiplying the Warrant Share Number
immediately prior to such adjustment in the Warrant Price by a fraction, the
numerator of which shall be the Warrant Price immediately before giving effect
to such adjustment and the denominator of which shall be the Warrant Price
immediately after giving effect to such adjustment. If the Issuer shall be in
default under any provision contained in Section 3 of this Warrant so that
shares issued at the Warrant Price adjusted in accordance with this Section 4
would not be validly issued, the adjustment of the Warrant Share Number provided
for in the foregoing sentence shall nonetheless be made and the Holder of this
Warrant shall be entitled to purchase such greater number of shares at the
lowest price at which such shares may then be validly issued under applicable
law. Such exercise shall not constitute a waiver of any claim arising against
the Issuer by reason of its default under Section 3 of this Warrant.

         (i) FORM OF WARRANT AFTER ADJUSTMENTS. The form of this Warrant need
not be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

         5.  NOTICE OF ADJUSTMENTS. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
PROVIDED that the Issuer shall have ten (10) days after receipt of notice from

Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty (30) days after submission
to it of such dispute. Such opinion shall be final and binding on the parties
hereto. The fees and expenses of such accounting firm shall be paid by the
Issuer.

         6.  FRACTIONAL SHARES. No fractional shares of Warrant Stock will be
issued in connection with and exercise hereof, but in lieu of such fractional
shares, the Issuer shall make a cash payment therefor equal in amount to the
product of the applicable fraction multiplied by the Per Share Market Value then
in effect.

         7.  CALL. Notwithstanding anything herein to the contrary, the Issuer,
at its option, may provide the Holder of this Warrant written notice pursuant to
Section 12 (the "Call Notice") that this Warrant shall terminate on the
twentieth (20th) day following the date of delivery of the Call Notice (such

(20) days prior to the action in question and not less than ten (10) days prior
to the record date or the date on which the Issuer's transfer books are closed
in respect thereto. The Issuer shall give to the Holder notice of all meetings

manner as notice of any meetings of stockholders is required to be given to
stockholders who do not waive such notice (or, if such requires no notice, then
two (2) Trading Days written notice thereof describing the matters upon which
action is to be taken). The Holder shall have the right to send two
representatives selected by it to each meeting, who shall be permitted to
attend, but not vote at, such meeting and any adjournments thereof. This Warrant
entitles the Holder to receive copies of all financial and other information
distributed or required to be distributed to the holders of the Common Stock.
