Date of Issuance: March 25, 2004


      FOR VALUE RECEIVED, subject to the provisions hereinafter set forth, the
undersigned, Cytomedix, Inc., 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 Term (as hereinafter defined), 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 9 hereof.

      1. Term. The term of this Warrant shall commence on March 25, 2004 and
shall expire at 5:00 p.m., eastern time, on March 25, 2009 (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 during the Term commencing on March 25, 2004
and expiring on March 25, 2009.



                                       2


      (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 by wire transfer to an account designated by the Issuer, (ii) by
"cashless exercise" in accordance with the provisions of subsection (c) of this
Section 2, but only when a registration statement under the Securities Act
providing for the resale of the Warrant Stock is not then in effect, or (iii) by
a combination of the foregoing methods of payment selected by the Holder of this
Warrant.

      (c) Cashless Exercise. Notwithstanding any provisions herein to the
contrary and commencing one (1) year following the Original Issue Date, if (i)
the Per Share Market Value of one share of Common Stock is greater than the
Warrant Price (at the date of calculation as set forth below) and (ii) a
registration statement under the Securities Act providing for the resale of the
Warrant Stock is not then in effect, in lieu of exercising this Warrant by
payment of cash, the Holder may exercise this Warrant by a cashless exercise and
shall receive the number of shares of Common Stock equal to an amount (as
determined below) by surrender of this Warrant at the principal office of the
Issuer together with the properly endorsed Notice of Exercise in which event the
Issuer shall issue to the Holder a number of shares of Common Stock computed
using the following formula:



               
            X = Y - (A)(Y)
                           B

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

            Y        = the number of shares of Common Stock purchasable
                     upon exercise of all of the Warrant or, if only a
                     portion of the Warrant is being exercised, the
                     portion of the Warrant being exercised.

            A =      the Warrant Price.

            B = the Per Share Market Value of one share of Common Stock.


      (d) 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 or, at the request of the Holder (provided that a registration
statement under the Securities Act providing for the resale of the Warrant Stock
is then in effect and the Company's transfer agent is participating in the DTC
Fast Automated Securities Transfer Program), issued and delivered to the
Depository Trust Company account on the Holder's behalf via the Deposit
Withdrawal Agent Commission System ("DWAC") 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


                                       2


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 a reasonable time, not exceeding seven (7)
Trading Days after such exercise.

      (e) Transferability of Warrant. Subject to Section 2(g), this Warrant may
be transferred by a Holder without the consent of the Issuer. If transferred
pursuant to this paragraph and subject to the provisions of subsection (g) 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 thereto.

      (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 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.

      (g) 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 CYTOMEDIX,


                                       3


      INC. SHALL HAVE RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO
      CYTOMEDIX, INC. THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES
      ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT
      REQUIRED.

            (iii) The Issuer agrees to reissue this Warrant or certificates
      representing any of the Warrant Stock, without the legend set forth above
      if at such time, prior to making any transfer of any such securities, the
      Holder shall give written notice to the Issuer describing the manner and
      terms of such transfer and removal as the Issuer may reasonably request.
      Such proposed transfer and removal will not be effected until: (a) either
      (i) the Issuer has received an opinion of counsel reasonably satisfactory
      to the Issuer, to the effect that the registration of such securities
      under the Securities Act is not required in connection with such proposed
      transfer, (ii) a registration statement under the Securities Act covering
      such proposed disposition has been filed by the Issuer with the Securities
      and Exchange Commission and has become effective under the Securities Act
      and the holder has complied with any prospectus delivery requirements,
      (iii) the Issuer has received other evidence reasonably satisfactory to
      the Issuer that such registration and qualification under the Securities
      Act and state securities laws are not required, or (iv) the Holder
      provides the Issuer with reasonable assurances that such security can be
      sold pursuant to Rule 144 under the Securities Act; and (b) either (i) the
      Issuer has received an opinion of counsel reasonably satisfactory to the
      Issuer, to the effect that registration or qualification under the
      securities or "blue sky" laws of any state is not required in connection
      with such proposed disposition, or (ii) compliance with applicable state
      securities or "blue sky" laws has been effected or a valid exemption
      exists with respect thereto. The Issuer will respond to any such notice
      from a holder within five (5) business days. In the case of any proposed
      transfer under this Section 2(g), the Issuer will use reasonable efforts
      to comply with any such applicable state securities or "blue sky" laws,
      but shall in no event be required, (x) to qualify to do business in any
      state where it is not then qualified, (y) to take any action that would
      subject it to tax or to the general service of process in any state where
      it is not then subject, or (z) to comply with state securities or "blue
      sky" laws of any state for which registration by coordination is
      unavailable to the Issuer. The restrictions on transfer contained in this
      Section 2(g) shall be in addition to, and not by way of limitation of, any
      other restrictions on transfer contained in any other section of this
      Warrant. Whenever a certificate representing the Warrant Stock is required
      to be issued to a the Holder without a legend, in lieu of delivering
      physical certificates representing the Warrant Stock, provided the
      Issuer's transfer agent is participating in the Depository Trust Company
      ("DTC") Fast Automated Securities Transfer program, the Issuer shall use
      its reasonable best efforts to cause its transfer agent to electronically
      transmit the Warrant Stock to the Holder by crediting the account of the
      Holder's Prime Broker with DTC through its Deposit Withdrawal Agent
      Commission ("DWAC") system (to the extent not inconsistent with any
      provisions of this Warrant or the Purchase Agreement).



                                       4


      (h) In no event may the Holder exercise this Warrant in whole or in part
unless the Holder is an "accredited investor" as defined in Regulation D under
the Securities Act.

      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, when issued in accordance with the
terms of this Warrant, be duly authorized, validly issued, fully paid and
non-assessable and free from all taxes, liens and charges created by or through
the 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 reasonable 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 (provided that such Warrant
Stock has been registered pursuant to a registration statement under the
Securities Act then in effect), 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 the rights of the Holders of
the Warrants in their capacity as Holders of the Warrants, (iii) take all such
action as may be reasonably necessary in order that the Issuer may validly and


                                       5


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 reasonable
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.

      4. Adjustment of Warrant Price and Warrant Share Number. The number of
shares of Common Stock for which this Warrant is exercisable, and the price at
which such shares may be purchased upon exercise of this Warrant, shall be
subject to adjustment from time to time as set forth in this Section 4. The
Issuer shall give the Holder notice of any event described below which requires
an adjustment pursuant to this Section 4 in accordance with Section 5.

      (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 or merge with
      or into another corporation where the holders of outstanding Voting Stock
      prior to such merger or consolidation do not own over 50% of the
      outstanding Voting Stock of the merged or consolidated entity immediately
      after such merger or consolidation, or (b) sell all or substantially all
      of its properties or assets to any other Person, or (c) change the Common
      Stock to the same or different number of shares of any class or classes of
      stock, whether by reclassification, exchange, substitution or otherwise
      (other than by way of a stock split or combination of shares or stock
      dividends or distributions provided for in Section 4(b) or Section 4(c)),
      or (d) effect a capital reorganization (other than by way of a stock split
      or combination of shares or stock dividends or distributions provided for
      in Section 4(b) or Section 4(c)), 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 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 elsewhere in this Section 4.

            (ii) Notwithstanding anything contained in this Warrant to the
      contrary, a Triggering Event shall not be deemed to have occurred if,
      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


                                       6


      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 a written acknowledgement
      executed by the President or Chief Financial Officer of the Company,
      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.

      (b) Stock Dividends, Subdivisions and Combinations. If at any time the
Issuer shall:

            (i) make or issue or set a record date for the holders of its Common
      Stock for the purpose of entitling them to receive a dividend payable in,
      or other distribution of, shares of Common Stock,

            (ii) subdivide its outstanding shares of Common Stock into a larger
      number of shares of Common Stock, or

            (iii) combine its outstanding shares of Common Stock into a smaller
      number of shares of Common Stock,

then (1) the number of shares of Common Stock for which this Warrant is
exercisable immediately after the occurrence of any such event shall be adjusted
to equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the occurrence of such event would own or be entitled to
receive after the happening of such event, and (2) the Warrant Price then in
effect shall be adjusted to equal (A) the Warrant Price then in effect
multiplied by the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to the adjustment divided by (B) the number of
shares of Common Stock for which this Warrant is exercisable immediately after
such adjustment.

Notwithstanding the foregoing, if such record date shall have been fixed and
such dividend is not fully paid or if such distribution is not fully made on the
date fixed therefor, the Warrant Price shall be adjusted pursuant to this
paragraph as of the time of actual payment of such dividends or distributions.

      (c) Certain Other Distributions. If at any time the Issuer shall make or
issue or set a record date for the determination of the holders of its Common
Stock for the purpose of entitling them to receive any dividend or other
distribution of:

            (i) cash (other than a cash dividend payable out of earnings or


                                       7


      earned surplus legally available for the payment of dividends under the
      laws of the jurisdiction of incorporation of the Issuer),

            (ii) any evidences of its indebtedness, any shares of stock of any
      class or any other securities or property of any nature whatsoever (other
      than cash, Common Stock Equivalents or Additional Shares of Common Stock),
      or

            (iii) any warrants or other rights to subscribe for or purchase any
      evidences of its indebtedness, any shares of stock of any class or any
      other securities or property of any nature whatsoever (other than cash,
      Common Stock Equivalents or Additional Shares of Common Stock),

then (1) the number of shares of Common Stock for which this Warrant is
exercisable shall be adjusted to equal the product of the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to such
adjustment multiplied by a fraction (A) the numerator of which shall be the Per
Share Market Value of Common Stock at the date of taking such record and (B) the
denominator of which shall be such Per Share Market Value minus the amount
allocable to one share of Common Stock of any such cash so distributable and of
the fair value (as determined in good faith by the Board of Directors of the
Issuer and supported by an opinion from an investment banking firm of recognized
national standing acceptable to (but not affiliated with) the Holder) of any and
all such evidences of indebtedness, shares of stock, other securities or
property or warrants or other subscription or purchase rights so distributable,
and (2) the Warrant Price then in effect shall be adjusted to equal (A) the
Warrant Price then in effect multiplied by the number of shares of Common Stock
for which this Warrant is exercisable immediately prior to the adjustment
divided by (B) the number of shares of Common Stock for which this Warrant is
exercisable immediately after such adjustment. A reclassification of the 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) into shares of Common Stock and shares of any
other class of stock shall be deemed a distribution by the Issuer to the holders
of its Common Stock of such shares of such other class of stock within the
meaning of this Section 4(c) and, if the outstanding shares of Common Stock
shall be changed into a larger or smaller number of shares of Common Stock as a
part of such reclassification, such change shall be deemed a subdivision or
combination, as the case may be, of the outstanding shares of Common Stock
within the meaning of Section 4(b).

Notwithstanding the foregoing, if such record date shall have been fixed and
such dividend is not fully paid or if such distribution is not fully made on the
date fixed therefor, the Warrant Price shall be adjusted pursuant to this
Section 4(c) as of the time of actual payment of such dividends or
distributions.

      (d) Issuance of Additional Shares of Common Stock.

            (i) In the event the Issuer shall at any time following the Original
Issue Date 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 without
consideration, then the Warrant Price upon each such issuance shall be adjusted
to that price determined by multiplying the Warrant Price then in effect by a
fraction:



                                       8


            (A) the numerator of which shall be equal to the sum of (x) the
      number of shares of Outstanding Common Stock immediately prior to the
      issuance of such Additional Shares of Common Stock plus (y) 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

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

            (ii) No adjustment of the number of shares of Common Stock for which
this Warrant shall be exercisable shall be made under paragraph (i) of Section
4(d) upon the issuance of any Additional Shares of Common Stock which are issued
pursuant to the exercise of any Common Stock Equivalents, if any such adjustment
shall previously have been made upon the issuance of such Common Stock
Equivalents (or upon the issuance of any warrant or other rights therefor)
pursuant to Section 4(e).

      (e) Issuance of Warrants or Other Rights. If at any time the Issuer shall
take a record of the holders of its Common Stock for the purpose of entitling
them to receive a distribution of, or shall in any manner (whether directly or
by assumption in a merger in which the Issuer is the surviving corporation)
issue or sell, any Common Stock Equivalents (or issue any warrant or other
rights therefor), whether or not the rights to exchange or convert thereunder
are immediately exercisable, and the price per share for which Common Stock is
issuable upon the exercise of such Common Stock Equivalents (or any warrant or
other rights therefor) shall be less than the Warrant Price in effect
immediately prior to the time of such issue or sale, then the number of shares
for which this Warrant is exercisable and the Warrant Price then in effect shall
be adjusted as provided in Section 4(d) on the basis that the maximum number of
Additional Shares of Common Stock issuable pursuant to all such Common Stock
Equivalents (or upon the issuance of any warrant or other rights therefor) shall
be deemed to have been issued and outstanding and the Issuer shall have received
all of the consideration payable therefor, if any, as of the date of the actual
issuance of such warrants or other rights. No adjustments of the Warrant Price
then in effect or the number of Warrant Shares for which this Warrant is
exercisable shall be made upon the actual issue of such Common Stock or of such
Common Stock Equivalents upon exercise of such warrants or other rights or upon
the actual issue of such Common Stock upon such conversion or exchange of such
Common Stock Equivalents.

      (f) Issuance of Common Stock Equivalents. If at any time the Issuer shall
issue or sell any Common Stock Equivalents, whether or not the rights to
exchange or convert thereunder are immediately exercisable, and the aggregate
price per share for which Common Stock is issuable upon such conversion or
exchange plus the consideration received by the Issuer for issuance of such
Common Stock Equivalent divided by the number of shares of Common Stock issuable
pursuant to such Common Stock Equivalent shall be less than the Warrant Price in
effect immediately prior to the time of such issue or sale, then the number of
shares of Common Stock for which this Warrant is exercisable and the Warrant
Price then in effect shall be adjusted as provided in Section 4(d) on the basis
that the maximum number of Additional Shares of Common Stock necessary to effect


                                       9


the conversion or exchange of all such Common Stock Equivalents shall be deemed
to have been issued and outstanding and the Issuer shall have received all of
the consideration payable therefor, if any, as of the date of actual issuance of
such Common Stock Equivalents. No further adjustment of the number of shares of
Common Stock for which this Warrant is exercisable and the Warrant Price then in
effect shall be made under this Section 4(e) upon the issuance of any Common
Stock Equivalents which are issued pursuant to the exercise of any warrants or
other subscription or purchase rights therefor, if any such adjustment shall
previously have been made upon the issuance of such warrants or other rights
pursuant to this Section 4(e). No further adjustments of the number of shares of
Common Stock for which this Warrant is exercisable and the Warrant Price then in
effect shall be made upon the actual issue of such Common Stock upon conversion
or exchange of such Common Stock Equivalents.

      (g) Superseding Adjustment. If, at any time after any adjustment of the
number of shares of Common Stock for which this Warrant is exercisable and the
Warrant Price then in effect shall have been made pursuant to Section 4(e) as
the result of any issuance of Common Stock Equivalents, and (i) such Common
Stock Equivalents, or the right of conversion or exchange in such Common Stock
Equivalents, shall expire, and all or a portion of such or the right of
conversion or exchange with respect to all or a portion of such Common Stock
Equivalents, as the case may be, shall not have been exercised, or (ii) the
consideration per share for which shares of Common Stock are issuable pursuant
to such Common Stock Equivalents shall be increased, then such previous
adjustment shall be rescinded and annulled and the Additional Shares of Common
Stock which were deemed to have been issued by virtue of the computation made in
connection with the adjustment so rescinded and annulled shall no longer be
deemed to have been issued by virtue of such computation. Upon the occurrence of
an event set forth in this Section 4(g) above, there shall be a recomputation
made of the effect of such Common Stock Equivalents on the basis of: (i)
treating the number of Additional Shares of Common Stock theretofore actually
issued or issuable pursuant to the previous exercise of Common Stock Equivalents
or any such right of conversion or exchange, as having been issued on the date
or dates of any such exercise and for the consideration actually received and
receivable therefor, and (ii) treating any such Common Stock Equivalents which
then remain outstanding as having been granted or issued immediately after the
time of such increase of the consideration per share for which Additional Shares
of Common Stock are issuable under such Common Stock Equivalents; whereupon a
new adjustment of the number of shares of Common Stock for which this Warrant is
exercisable and the Warrant Price then in effect shall be made, which new
adjustment shall supersede the previous adjustment so rescinded and annulled.

      (h) Purchase of Common Stock by the Issuer. If the Issuer at any time
while this Warrant is outstanding shall, directly or indirectly through a
Subsidiary or otherwise, purchase, redeem or otherwise acquire any shares of
Common Stock at a price per share greater than the Per Share Market Value, then
the Warrant Price upon each such purchase, redemption or acquisition shall be
adjusted to that price determined by multiplying such Warrant Price by a
fraction (i) the numerator of which shall be the number of shares of Outstanding
Common Stock immediately prior to such purchase, redemption or acquisition minus
the number of shares of Common Stock which the aggregate consideration for the
total number of such shares of Common Stock so purchased, redeemed or acquired
would purchase at the Per Share Market Value; and (ii) the denominator of which
shall be the number of shares of Outstanding Common Stock immediately after such
purchase, redemption or acquisition. For the purposes of this subsection (h),


                                       10


the date as of which the Per Share Market Price shall be computed shall be the
earlier of (x) the date on which the Issuer shall enter into a firm contract for
the purchase, redemption or acquisition of such Common Stock, or (y) the date of
actual purchase, redemption or acquisition of such Common Stock. For the
purposes of this subsection (h), a purchase, redemption or acquisition of a
Common Stock Equivalent shall be deemed to be a purchase of the underlying
Common Stock, and the computation herein required shall be made on the basis of
the full exercise, conversion or exchange of such Common Stock Equivalent on the
date as of which such computation is required hereby to be made, whether or not
such Common Stock Equivalent is actually exercisable, convertible or
exchangeable on such date.

      (i) Other Provisions applicable to Adjustments under this Section. The
following provisions shall be applicable to the making of adjustments of the
number of shares of Common Stock for which this Warrant is exercisable and the
Warrant Price then in effect provided for in this Section 4:

            (i) Computation of Consideration. To the extent that any Additional
Shares of Common Stock or any Common Stock Equivalents (or any warrants or other
rights therefor) shall be issued for cash consideration, the consideration
received by the Issuer therefor shall be the amount of the cash 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 initial public offering price (in any such case subtracting any
amounts paid or receivable for accrued interest or accrued dividends and without
taking into account any compensation, discounts or expenses paid or incurred by
the Issuer for and in the underwriting of, or otherwise in connection with, the
issuance thereof). In connection with any merger or consolidation in which the
Issuer is the surviving corporation (other than any consolidation or merger in
which the previously outstanding shares of Common Stock of the Issuer shall be
changed to or exchanged for the stock or other securities of another
corporation), the amount of consideration therefore shall be, deemed to be the
fair value, as determined reasonably and in good faith by the Board, of such
portion of the assets and business of the nonsurviving corporation as the Board
may determine to be attributable to such shares of Common Stock or Common Stock
Equivalents, as the case may be. The consideration for any Additional Shares of
Common Stock issuable pursuant to any warrants or other rights to subscribe for
or purchase the same shall be the consideration received by the Issuer for
issuing such warrants or other rights plus the additional consideration payable
to the Issuer upon exercise of such warrants or other rights. The consideration
for any Additional Shares of Common Stock issuable pursuant to the terms of any
Common Stock Equivalents shall be the consideration received by the Issuer for
issuing warrants or other rights to subscribe for or purchase such Common Stock
Equivalents, plus the consideration paid or payable to the Issuer in respect of
the subscription for or purchase of such Common Stock Equivalents, plus the
additional consideration, if any, payable to the Issuer upon the exercise of the
right of conversion or exchange in such Common Stock Equivalents. In the event
of any consolidation or merger of the Issuer in which the Issuer is not the
surviving corporation or in which the previously outstanding shares of Common
Stock of the Issuer shall be changed into or exchanged for the stock or other


                                       11


securities of another corporation, or in the event of any sale of all or
substantially all of the assets of the Issuer for stock or other securities of
any corporation, the Issuer shall be deemed to have issued a number of shares of
its Common Stock for stock or securities or other property of the other
corporation computed on the basis of the actual exchange ratio on which the
transaction was predicated, and for a consideration equal to the fair market
value on the date of such transaction of all such stock or securities or other
property of the other corporation. In the event any consideration received by
the Issuer for any securities consists of property other than cash, the fair
market value thereof at the time of issuance or as otherwise applicable shall be
as determined in good faith by the Board. In the event Common Stock is issued
with other shares or securities or other assets of the Issuer for consideration
which covers both, the consideration computed as provided in this Section
4(i)(i) shall be allocated among such securities and assets as determined in
good faith by the Board.

            (ii) When Adjustments to Be Made. The adjustments required by this
Section 4 shall be made whenever and as often as any specified event requiring
an adjustment shall occur, except that any adjustment of the number of shares of
Common Stock for which this Warrant is exercisable that would otherwise be
required may be postponed (except in the case of a subdivision or combination of
shares of the Common Stock, as provided for in Section 4(b)) up to, but not
beyond the date of exercise if such adjustment either by itself or with other
adjustments not previously made adds or subtracts less than one percent (1%) of
the shares of Common Stock for which this Warrant is exercisable immediately
prior to the making of such adjustment. Any adjustment representing a change of
less than such minimum amount (except as aforesaid) which is postponed shall be
carried forward and made as soon as such adjustment, together with other
adjustments required by this Section 4 and not previously made, would result in
a minimum adjustment or on the date of exercise. For the purpose of any
adjustment, any specified event shall be deemed to have occurred at the close of
business on the date of its occurrence.

            (iii) Fractional Interests. In computing adjustments under this
Section 4, fractional interests in Common Stock shall be taken into account to
the nearest one one-hundredth (1/100th) of a share.

            (iv) When Adjustment Not Required. If the Issuer shall take a record
of the holders of its Common Stock for the purpose of entitling them to receive
a dividend or distribution or subscription or purchase rights and shall,
thereafter and before the distribution to stockholders thereof, legally abandon
its plan to pay or deliver such dividend, distribution, subscription or purchase
rights, then thereafter no adjustment shall be required by reason of the taking
of such record and any such adjustment previously made in respect thereof shall
be rescinded and annulled.

      (j) 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.

      (k) Escrow of Warrant Stock. If after any property becomes distributable
pursuant to this Section 4 by reason of the taking of any record of the holders
of Common Stock, but prior to the occurrence of the event for which such record
is taken, and the Holder exercises this Warrant, any shares of Common Stock
issuable upon exercise by reason of such adjustment shall be deemed the last
shares of Common Stock for which this Warrant is exercised (notwithstanding any


                                       12


other provision to the contrary herein) and such shares or other property shall
be held in escrow for the Holder by the Issuer to be issued to the Holder upon
and to the extent that the event actually takes place, upon payment of the
current Warrant Price. Notwithstanding any other provision to the contrary
herein, if the event for which such record was taken fails to occur or is
rescinded, then such escrowed shares shall be cancelled by the Issuer and
escrowed property returned.

      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 the Issuer's
independent, outside accountant. The Issuer shall use its best efforts to cause
the accountant to perform the calculations and notify the Issuer and the Holder
of the results no later than five (5) business days from the time it receives
the disputed calculation. Such accountant's calculation shall be binding upon
all parties absent manifest error. The reasonable expenses of such accountant in
making such determination shall be paid by the Issuer, in the event the Holder's
calculation was correct, or by the Holder, in the event the Issuer's calculation
was correct, or equally by the Issuer and the Holder in the event that neither
the Issuer's or the Holder's calculation was correct.

      6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with any 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. Ownership Cap and Certain Exercise Restriction. The Holder may not
exercise the Warrant hereunder to the extent such exercise would result in the
Holder beneficially owning (as determined in accordance with Section 13(d) of
the Exchange Act and the rules thereunder) in excess of 9.999% of the then
issued and outstanding shares of Common Stock, including shares issuable upon
exercise of the Warrant held by the Holder after application of this Section.

      8. Call. Notwithstanding anything herein to the contrary, commencing
twelve (12) months following the effective date of a registration statement
under the Securities Act providing for the resale of the Warrant Stock and the
shares of Common Stock issuable upon conversion of the Issuer's Series C
Preferred Stock issued pursuant to the Purchase Agreement (the "Registration
Statement"), the Issuer, at its option, may call up to one hundred percent
(100%) of this Warrant if the Per Share Market Value of the Common Stock has
been greater than $3.00 (as may be adjusted for any stock splits or combinations
of the Common Stock) for a period of ten (10) consecutive Trading Days
immediately prior to the date of delivery of the Call Notice (a "Call Notice
Period") by providing the Holder of this Warrant written notice pursuant to
Section 13 (the "Call Notice"); provided, that (a) the Registration Statement is
then in effect and has been effective, without lapse or suspension of any kind,
for a period of 60 consecutive calendar days, (b) trading in the Common Stock
shall not have been suspended by the Securities and Exchange Commission or the


                                       13


OTC Bulletin Board and (c) the Issuer is in material compliance with the terms
and conditions of this Warrant and the other Transaction Documents (as defined
in the Purchase Agreement); provided, further, that the Registration Statement
is in effect from the date of delivery of the Call Notice until the date which
is the later of (i) the date the Holder exercises the Warrant pursuant to the
Call Notice and (ii) the 20th day after the Holder receives the Call Notice (the
"Early Termination Date"). The rights and privileges granted pursuant to this
Warrant with respect to the shares of Warrant Stock subject to the Call Notice
(the "Called Warrant Shares") shall expire on the Early Termination Date if this
Warrant is not exercised with respect to such Called Warrant Shares prior to
such Early Termination Date. In the event this Warrant is not exercised with
respect to the Called Warrant Shares, the Issuer shall remit to the Holder of
this Warrant (A) $.01 per Called Warrant Share and (B) a new Warrant
representing the number of shares of Warrant Stock, if any, which shall not have
been subject to the Call Notice upon the Holder tendering to the Issuer the
applicable Warrant certificate. Notwithstanding anything in the foregoing to the
contrary, if the Holder may not exercise this Warrant as a result of the
restriction contained in Section 7 hereof, the Call Notice shall be deemed null
and void and shall not be deemed effective until the date that the Holder may
exercise this Warrant in accordance with Section 7 hereof.
