    FOR VALUE RECEIVED, subject to the provisions hereinafter set forth, the
undersigned, STARBASE CORPORATION, a Delaware corporation (together with its
successors and assigns, the "Issuer"), hereby certifies that

                           ---------------------------

or its registered assigns is entitled to subscribe for and purchase, during the
period specified in this non-transferable Warrant, up to __________ 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 7 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 5:00 p.m., New York City time, on November 20, 2006 (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.

        (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


<PAGE>


with respect to which this Warrant is then being exercised, payable at such
Holder's election by (i) certified or official bank check, or (ii) until the
Effectiveness Date of the Registration Statement, by "cashless exercise" 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 Closing Bid Price 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 cancelled 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) Ownership Cap. Notwithstanding anything to the contrary set forth in
Section 2 of this Warrant, at no time may a Holder of this Warrant exercise this
Warrant if the number of shares of Common Stock to be issued pursuant to such
exercise would exceed, when aggregated with all other shares of Common Stock
owned by such Holder at such time, the number of shares of Common Stock which
would result in such Holder owning more than 9.99% of all of the Common Stock
outstanding at such time; provided, however, that upon a Holder of this Warrant
providing the Issuer with 75 days notice (pursuant to Section 11 hereof) (the
"Waiver Notice") that such Holder would like to waive this Section 2(d) with
regard to any or all shares of Common Stock issuable upon exercise of this
Warrant, this Section 2(d) will be of no force or effect with regard to all or a
portion of the Warrant referenced in the Waiver Notice.

        (e) Transferability of Warrant. This Warrant may not be transferred by
the Holder without the prior written consent of the Issuer, such consent not to
be unreasonably withheld. If transferred pursuant to this Section 2(e) 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 a Warrant or 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 to this Warrant except as to the number of shares of Warrant Stock
issuable pursuant hereto.

        (f) Compliance with Securities Laws.

                (i) The Holder of this Warrant, by acceptance hereof,
        acknowledges that this Warrant and the shares of Warrant Stock to be
        issued upon exercise hereof are being acquired


                                      -2-
<PAGE>


        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
        of 1933, as amended (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:

                        THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN
                REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION IN
                RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE
                SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
                ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
                EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR
                PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT
                SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

                (iii) The restrictions imposed by this subsection (e) upon the
        transfer of this Warrant and the shares of Warrant Stock to be purchased
        upon exercise hereof shall terminate (A) when such securities shall have
        been effectively registered 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 or (C) upon the Issuer's receipt of
        other evidence reasonably satisfactory to the Issuer that such
        registration is 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 legends
        required by paragraph (ii) above relating to the Securities Act and
        state securities laws.

        (g) 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
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


                                      -3-
<PAGE>


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.

        (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
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


                                      -4-
<PAGE>


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, or is redeemed in connection with 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 and increases (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) 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 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.

               (i) 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.

               (ii) 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 11 hereof.


                                      -5-
<PAGE>


        (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.

        (c) 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) and
(b) of this Section 4), at a price per share less than the Warrant Price then in
effect 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 Warrant Price then in effect, and

                (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 (c) shall not apply under any of the
circumstances for which an adjustment is provided in subsections (a, or (b) of
this Section 4. No adjustment of the Warrant Price shall be made under this
subsection (c) 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 (d) of this Section 4 or (y) no adjustment was required pursuant to
subsection (d) of this Section 4. No adjustment of the Warrant Price shall be
made under this subsection (c) 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.

        (d) 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 shall 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 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 in effect at the time of such amendment,
then the Warrant Price upon each such issuance or amendment shall be adjusted as
provided in the first sentence of subsection (c) of this Section 4 on the basis
that (1) the maximum number of


                                      -6-
<PAGE>


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 for the issuance of such Additional Shares of Common Stock pursuant
to such Common Stock Equivalent. No adjustment of the Warrant Price shall be
made under this subsection (d) upon the issuance of any Convertible Security
which is issued pursuant to the exercise of any warrants or other subscription
or purchase rights therefor, if any adjustment shall previously have been made
in the Warrant Price then in effect upon the issuance of such warrants or other
rights pursuant to this subsection (d). If no adjustment is required under this
subsection (d) upon issuance of any Common Stock Equivalent or once an
adjustment is made under this subsection (d) based upon the Warrant Price in
effect on the date of such adjustment, no further adjustment shall be made under
this subsection (d) based solely upon a change in the Warrant Price after such
date.

        (e) Other Provisions Applicable to Adjustments Under this Section 4. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

                (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 without a subscription 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 days (30) 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


                                      -7-
<PAGE>


        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 (e)) shall be deemed to have been received
        by the Issuer.

                (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.

        (f) 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 (e) 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.

        (g) 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.

        (h) 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


                                      -8-
<PAGE>


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 days (10) after receipt of notice from
such Holder of its selection of such firm to object thereto, in which case such
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 days (30) 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 Closing Bid Price on the
date of the exercise form.

by such notice. Copies of notices to the Holder shall be sent to the address set
forth for the Holder on Exhibit A to the Purchase Agreement.

        12. Warrant Agent. The Issuer may, by written notice to each Holder of
this Warrant, appoint an agent having an office in New York, New York for the
purpose of issuing shares of Warrant Stock on the exercise of this Warrant
pursuant to subsection (b) of Section 2 hereof, exchanging this Warrant pursuant

        13. Remedies. The Issuer stipulates that the remedies at law of the
Holder of this Warrant in the event of any default or threatened default by the

deemed modified to the extent necessary to make it enforceable by such court or
agency. If any such provision is not enforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
