Date of Issuance: March 31, 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 31, 2004 and
shall expire at 5:00 p.m., central time, on March 31, 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

         (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:


<PAGE>

                  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
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 five (5)
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. Notwithstanding anything herein to the
contrary, a Holder shall have no rights under this Warranty until the Delivery
Date. 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.


<PAGE>

         (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, 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).


<PAGE>

         (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 upon payment of all consideration due the Issuer for an Investment
in the Units, including the payment in full of all amounts due under any
Negotiable Term Promissory Note, 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. 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, and (iii) 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.


<PAGE>

         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 Delivery 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 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 after the Delivery Date 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


<PAGE>

                  (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 after the Delivery Date
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 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.


<PAGE>

         (d) Issuance of Additional Shares of Common Stock.

                  (i) In the event the Issuer shall at any time after the
         Delivery 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:

                           (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 after the
Delivery Date 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 after the
Delivery Date 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 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.


<PAGE>

         (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
after the Delivery Date 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), 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

<PAGE>

         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 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.


<PAGE>

         (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 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 Restrictions. 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
twenty-four (24) months following the effective date of a registration statement
under the Securities Act providing for the resale of the Warrant Stock (the
"Registration Statement"), the Issuer, at its option, may call up to fifty
percent (50%) 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 OTC Bulletin Board and (c) the Issuer is in material compliance with the
terms and conditions of this Warrant; 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.
