    FOR VALUE
RECEIVED, subject to the provisions hereinafter set forth, the undersigned,
Valcent Products Inc., a corporation organized under the laws of the Province of
Alberta, Canada (together with its successors and assigns, the “Issuer”), hereby
certifies that _______________, or its registered assigns is entitled to
subscribe for and purchase, during the period specified in this Warrant, up to
______________ shares (subject to adjustment as hereinafter provided) of the
duly authorized, validly issued, fully paid and non-assessable Common Stock of
the Issuer, at an exercise price per share equal to the Warrant Price then in
effect, subject, however, to the provisions and upon the terms and conditions
hereinafter set forth.  Capitalized terms used in this Warrant and not
otherwise defined herein shall have the respective meanings specified in Section
9 hereof.

    


    1.           Term.  The
right to subscribe for and purchase shares of Warrant Stock represented hereby
shall commence on July 16, 2008 and shall expire at 5:00 p.m., eastern time, on

    2.           Method of Exercise Payment;
Issuance of New Warrant; Transfer and Exchange.

    (a)          Time of
Exercise.  The purchase rights represented by this Warrant may
be exercised in whole or in part at any time and from time to time during the
Term commencing on July 16, 2008.

    


    (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, 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 180 days following the Original Issue Date, if 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), 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 (the “Delivery Date”) or,
if the Issuer’s securities are eligible for such manner of delivery, then at the
request of the Holder, issued and delivered to the Depository Trust Company
(“DTC”) 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 such
time.

    (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, this Warrant may be transferred on the
books of the Issuer by the Holder hereof in person or by the Holder’s 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 and
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 VALCENT PRODUCTS INC. SHALL HAVE RECEIVED AN OPINION OF
COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER
THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT
REQUIRED.


    
      
         


      

      
        3

        
          

        

      

      
         


      

    

     

    


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

    


    (h)          Buy In.

    


    In addition to any other rights
available to the Holder, if the Issuer fails to cause its transfer agent to
transmit to the Holder  a certificate or certificates representing the
Warrant Stock pursuant to an exercise on or before the Delivery Date, and if
after such date the Holder is required by its broker to purchase (in an open
market transaction or otherwise) shares of Common Stock to deliver in
satisfaction of a sale by the Holder of the Warrant Stock which the Holder
anticipated receiving upon such exercise (a “Buy-In”), then the
Issuer shall (1) pay in cash to the Holder the amount by which (x) the Holder’s
total purchase price (including brokerage commissions, if any) for the shares of
Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the
number of shares of Warrant Stock that the Issuer was required to deliver to the
Holder in connection with the exercise at issue times, (B) the price at which
the sell order giving rise to such purchase obligation was executed, and (2) at
the option of the Holder, either reinstate the portion of the Warrant and
equivalent number of shares of Warrant Stock for which such exercise was not
honored or deliver to the Holder the number of shares of Common Stock that would
have been issued had the Issuer timely complied with its exercise and delivery
obligations hereunder.  For example, if the Holder purchases Common
Stock having a total purchase price of $11,000 to cover a Buy-In with respect to
an attempted exercise of shares of Common Stock with an aggregate sale price
giving rise to such purchase obligation of $10,000, under clause (1) of the
immediately preceding sentence the Issuer shall be required to pay the Holder
$1,000.  The Holder shall provide the Issuer written notice indicating
the amounts payable to the Holder in respect of the Buy-In, together with
applicable confirmations and other evidence reasonably requested by the
Issuer.  Nothing herein shall limit a Holder’s right to pursue any
other remedies available to it hereunder, at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief with
respect to the Issuer’s failure to timely deliver certificates representing
shares of Common Stock upon exercise of this Warrant as required pursuant to the
terms hereof.

    (i)           Redemption.  On
the Redemption Date (as defined below), the Issuer may cause this Warrant to be
redeemed in whole, but not in part, at a price equal to $0.01 multiplied by the
number of shares of Warrant Stock underlying this Warrant by providing ten (10)
Trading Days’ prior written notice of such redemption; provided, that, it is
understood and agreed that during such ten Trading Day period, the Holder may
exercise its rights to exercise this Warrant in whole or in part; and provided,
further, that no redemption shall hereunder occur unless (i) the Equity
Conditions with respect to all shares of Warrant Stock are satisfied (or waived
in writing by the Holder) on the Redemption Date, and (ii) the Holder would
otherwise be permitted to exercise this Warrant in full under Section 8
hereof.  Upon the receipt of a notice that the Warrant is being
redeemed the Holder may exercise this Warrant pursuant to the cashless exercise
provisions provided in Section 2(c) of this Warrant.  As used herein,
a “Redemption Date” shall be a date selected by the Issuer following the
satisfaction of the Equity Conditions on which the Per Share Market Value has
exceeded $1.50 for of a period of twenty (20) consecutive Trading Days;
provided, that, the Equity Conditions have been satisfied with respect to all
shares of Warrant Stock underlying this Warrant, without lapse or restriction of
any kind, for such twenty (20) consecutive Trading Day period.

    


    3.           Stock Fully Paid;
Reservation and Listing of Shares; Covenants.

    


    (a)          Stock Fully
Paid.  The Issuer represents, warrants, covenants and agrees
that all shares of Warrant Stock which may be issued upon the exercise of this
Warrant or otherwise hereunder will, upon issuance, be duly authorized, validly
issued, fully paid and non-assessable and free from all taxes, liens and charges
created by or through Issuer.  The Issuer further covenants and agrees
that during the period within which this Warrant may be exercised, the Issuer
will at all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a number of shares of Common Stock equal to at least
120% of the aggregate number of shares of Common Stock exercisable hereunder to
provide for the exercise of this Warrant (without regard to limitations on
exercisability set forth in Section 8).

    


    (b)          Reservation.  If
any shares of Common Stock required to be reserved for issuance upon exercise of
this Warrant or as otherwise provided hereunder require registration or
qualification with any governmental authority under any federal or state law
before such shares may be so issued, the Issuer will in good faith use its best
efforts as expeditiously as possible at its expense to cause such shares to be
duly registered or qualified.  If the Issuer shall list any shares of
Common Stock on any securities exchange or market it will, at its expense, list
thereon, maintain and increase when necessary such listing, of, all shares of
Warrant Stock from time to time issued upon exercise of this Warrant or as
otherwise provided hereunder, and, to the extent permissible under the
applicable securities exchange’s 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, (iii) take all such
action as may be reasonably necessary in order that the Issuer may validly and
legally issue fully paid and nonassessable shares of Common Stock, free and
clear of any liens, claims, encumbrances and restrictions (other than as
provided herein) upon the exercise of this Warrant, and (iv) use its best
efforts to obtain all such authorizations, exemptions or consents from any
public regulatory body having jurisdiction thereof as may be reasonably
necessary to enable the Issuer to perform its obligations under this
Warrant.

    


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

    


    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.  Notwithstanding any
adjustment hereunder, at no time shall the Warrant Price be greater than $0.55
per share, except if it is adjusted pursuant to Section 4(b)(iii).

    


    (a)          Recapitalization,
Reorganization, Reclassification, Consolidation, Merger or
Sale.

    (i)              
In case the Issuer after the Original Issue Date shall do any of the following
(each, a “Triggering
Event”): (a) consolidate with or merge into any other Person and the
Issuer shall not be the continuing or surviving corporation of such
consolidation or merger, or (b) permit any other Person to consolidate with or
merge into the Issuer and the Issuer shall be the continuing or surviving Person
but, in connection with such consolidation or merger, any Capital Stock of the
Issuer shall be changed into or exchanged for Securities of any other Person or
cash or any other property, or (c) transfer all or substantially all of its
properties or assets to any other Person, or (d) effect a capital reorganization
or reclassification of its Capital Stock, then, and in the case of each such
Triggering Event, proper provision shall be made so that, upon the basis and the
terms and in the manner provided in this Warrant, the Holder of this Warrant
shall be entitled 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 (without giving effect to
the limitations on exercise set forth in Section 8 hereof) immediately prior
thereto (including the right to elect the type of consideration, if applicable),
subject to adjustments (subsequent to such corporate action) as nearly
equivalent as possible to the adjustments provided for elsewhere in this Section
4.  Unless the surviving entity in any such Triggering Event is a
public company under the Securities Exchange Act of 1934, the common equity
securities of which are traded or quoted on a national securities exchange or
the OTC Bulletin Board (a “Qualifying Entity”),
the Holder, at its option, shall be permitted to require that the Issuer pay to
the Holder an amount equal to the Black-Scholes value of this
Warrant.

    


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

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

    


    (i)              
set a record date or take a record of 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 (without giving effect to the limitations on exercise
set forth in Section 8 hereof), 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 (without giving effect to the limitations on
exercise set forth in Section 8 hereof) divided by (B) the number of shares of
Common Stock for which this Warrant is exercisable immediately after such
adjustment (without giving effect to the limitations on exercise set forth in
Section 8 hereof).

    


    (c)          Certain Other
Distributions.  If at any time the Issuer shall set a record
date or take a record 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, Additional Shares of Common Stock or Permitted Issuances),
or

     

     

    
 

    
      
        
        

      

      
        8

        
          

        

      

      
        
        

      

    

     

     

    (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,
Additional Shares of Common Stock or Permitted Issuances), 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 (without
giving effect to the limitations on exercise
set forth in Section 8 hereof) 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 reasonably acceptable to 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 (without giving effect to the
limitations on exercise set forth in Section 8 hereof) divided by (B) the number
of shares of Common Stock for which this Warrant is exercisable immediately
after such adjustment (without giving effect to the limitations on exercise set
forth in Section 8 hereof).  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).

    


    (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 the price equal
to the consideration per share paid for such Additional Shares of Common
Stock.

    


    (ii)             
No adjustment of the Warrant Price 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 or conversion 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 Sections 4(e) or 4(f), or in connection
with any Permitted Issuances.

    


    (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
warrants or options, whether or not immediately exercisable, and the Warrant
Consideration (hereafter defined) per share for which Common Stock is issuable
upon the exercise of such warrant or option shall be less than the Warrant Price
in effect immediately prior to the time of such issue or sale, then the Warrant
Price then in effect immediately prior to the time of such issue or sale, shall
be adjusted to the price equal to the Warrant Consideration per share for which
Common Stock is issuable upon the exercise of such warrant or
option.    No adjustments of the Warrant Price then in
effect 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 if adjustment has been previously made pursuant to this
section.  No adjustments of the Warrant Price shall be made under this
Section 4(e) in connection with any Permitted Issuances.


    
      
         


      

      
        9

        
          

        

      

      
         


      

    

     

    


    (f)           Issuance of Common Stock
Equivalents.  If at any time prior 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, whether or not the rights to exchange or
convert thereunder are immediately exercisable, and the Common Stock Equivalent
Consideration (hereafter defined) per share for which Common Stock is issuable
upon such conversion or exchange shall be less than the Warrant Price in effect
immediately prior to the time of such issue or sale, or if, after any such
issuance of Common Stock Equivalents, the price per share for which Additional
Shares of Common Stock may be issuable thereafter is amended or adjusted, and
such price as so amended shall be less than the applicable Conversion Price in
effect at the time of such amendment or adjustment, then the Warrant Price then
in effect immediately prior to the time of such issue or sale, shall upon each
such issuance or sale be adjusted to the price equal to the Common Stock
Equivalent Consideration per share paid for such Common Share
Equivalents.  No further adjustment of the Warrant Price then in
effect shall be made under this Section 4(f) 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 Section 4(e).  No further adjustments of 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 if adjustment shall have
previously been made pursuant to this section.  No adjustments of the
Warrant Price shall be made under this Section 4(f) in connection with any
Permitted Issuances.

    


    (g)          Superseding
Adjustment.  If, at any time after any adjustment of the
Warrant Price then in effect shall have been made pursuant to Section 4(e) or
Section 4(f) as the result of any issuance of warrants, other rights or Common
Stock Equivalents, and (i) such warrants or other rights, or the right of
conversion or exchange in such other Common Stock Equivalents, shall expire, and
all or a portion of such warrants or other rights, or the right of conversion or
exchange with respect to all or a portion of such other 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 solely by virtue of
provisions therein contained for an automatic increase in such consideration per
share upon the occurrence of a specified date or event, then for each
outstanding Warrant 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 or other property, if any, theretofore
actually issued or issuable pursuant to the previous exercise of any such
warrants or other rights 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 shares of Common Stock or other property are issuable under such
Common Stock Equivalents; whereupon a new adjustment of 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; Below Market Issuances.  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 Common
Stock outstanding 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 Common Stock outstanding 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.  If the Issuer
shall issue Common Stock or rights, options or warrants entitling the recipient
or holder thereof to subscribe for or purchase shares of Common Stock at a price
per share less than the Per Share Market Value on the date of issuance, but
higher than the Warrant Price then in effect, the Warrant Price shall be
multiplied by a fraction, of which the denominator shall be the number of shares
of the Common Stock outstanding on the date of issuance of such Common Stock or
rights or warrants plus the number of additional shares of Common Stock offered
for subscription or purchase, and of which the numerator shall be the number of
shares of the Common Stock outstanding on the date of issuance of such rights or
warrants plus the number of shares which the aggregate offering price of the
total number of shares so offered (assuming receipt by the Issuer in full of all
consideration payable upon exercise of such rights, options or warrants) would
purchase at such Per Share Market Value.  Such adjustment shall be
made whenever such securities are issued, and shall become effective immediately
after the record date (if applicable) for the determination of stockholders
entitled to receive such rights, options or warrants.

    (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).  To the extent that such issuance shall be for a
consideration other than cash, then, except as herein otherwise expressly
provided, the amount of such consideration shall be deemed to be the fair value
of such consideration at the time of such issuance as mutually de­termined
in good faith by the Board of Directors of the Issuer and the Majority
Holders.  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 divided by the number of shares of Common Stock
issuable upon the exercise of such warrant or right plus the additional
con­sideration payable to the Issuer upon exercise of such warrant or other
right for one share of Common Stock (together the “Warrant
Consideration”).  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 such Common Stock
Equivalent, divided by the number of shares of Common Stock issuable upon the
conversion or other exercise of such Common Stock Equivalent, plus the
additional consideration, if any, payable to the Issuer upon the exercise of the
right of conversion or exchange in such Common Stock Equivalent for one share of
Common Stock (together the “Common Stock Equivalent
Consideration”).  In case of the issuance at any time of any
Additional Shares of Common Stock or Common Stock Equivalents in payment or
satisfaction of any dividends upon any class of stock other than Common Stock,
the Issuer shall be deemed to have received for such Additional Shares of Common
Stock or Common Stock Equivalents a consideration equal to the amount of such
dividend so paid or satisfied.

    


    (ii)             
Adjustments of Number
of Shares.  In connection with an adjustment of the Warrant
Price pursuant to Sections (d), (e), (f), (g) and (h) of this
Section 4, the number of shares of Common Stock issuable hereunder shall be
increased such that the aggregate Warrant Price payable hereunder, after taking
into account the decrease in the Exercise Price, shall be equal to the aggregate
Warrant Price prior to such adjustment.

    (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 exercise of this Warrant.

    


    (k)       
  Escrow of
Property.  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, such property shall be held in escrow for
the Holder by the Issuer to be distributed to the Holder upon and to the extent
that the event actually takes place, upon payment of the then 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 property shall be returned to the Issuer.

    


    5.           Notice of
Adjustments.  Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an “adjustment”), the Issuer shall cause its Chief
Financial Officer to prepare and execute a certificate setting forth, in
reasonable detail, the event requiring the adjustment, the amount of the
adjustment, the method by which such adjustment was calculated (including a
description of the basis on which the Board made any determination hereunder),
and the Warrant Price and Warrant Share Number after giving effect to such
adjustment, and shall cause copies of such certificate to be delivered to the
Holder of this Warrant promptly after each adjustment.  Any dispute
between the Issuer and the Holder of this Warrant with respect to the matters
set forth in such certificate may at the option of the Holder of this Warrant be
submitted to one of the national accounting firms currently known as the “big
four” selected by the Holder, provided that the
Issuer shall have ten (10) days after receipt of notice from such Holder of its
selection of such firm to object thereto, in which case such Holder shall select
another such firm and the Issuer shall have no such right of
objection.  The firm selected by the Holder of this Warrant as
provided in the preceding sentence shall be instructed to deliver a written
opinion as to such matters to the Issuer and such Holder within thirty (30) days
after submission to it of such dispute.  Such opinion shall be final
and binding on the parties hereto.

    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 at its option either (a) 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 or (b) issue one whole share in lieu of such
fractional share.

    


    7.           [Intentionally
Reserved].

    


    8.         
 Certain Exercise
Restrictions.

     

    (a)          Notwithstanding
anything to the contrary set forth in this Warrant, at no time may a holder of
this Warrant exercise this Warrant if the number of shares of Common Stock to be
issued pursuant to such exercise would exceed, when aggregated with all other
shares of Common Stock owned by such holder at such time, the number of shares
of Common Stock which would result in such holder beneficially owning (as
determined in accordance with Section 13(d) of the Securities Exchange Act
of 1934, as amended, and the rules thereunder) in excess of 9.99% of all of the
Common Stock outstanding at such time; provided, however, that upon a holder of
this Warrant providing the Issuer with sixty-one (61) days notice (pursuant to
Section 13 hereof) (the “Waiver Notice”) that such holder would like to
waive this Section 8 with regard to any or all shares of Common Stock
issuable upon exercise of this Warrant, this Section 8 will be of no force
or effect with regard to all or a portion of the Warrant referenced in the
Waiver Notice; provided, further, that this Section 8(a) shall be of no further
force or effect during the sixty-one (61) days immediately preceding the
expiration of the term of this Warrant.
