      NACEL
Energy Corporation, a Wyoming corporation (the “Company”), hereby certifies
that, for good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, IROQUOIS MASTER FUND LTD., the registered holder hereof
or its permitted assigns (the “Holder”), is entitled, subject
to the terms set forth below, to purchase from the Company, at the Exercise
Price (as defined below) then in effect, upon exercise of this Warrant to
Purchase Common Stock (including any Warrants to Purchase Common Stock issued in
exchange, transfer or replacement hereof, the “Warrant”), at any time or
times on or after the Issuance Date, but not after 11:59 p.m., New York time, on
the Expiration Date (as defined below), 3,750,000 (subject to adjustment as
provided herein) fully paid and nonassessable shares of Common Stock (as defined
below) (the “Warrant Shares”). Except as
otherwise defined herein, capitalized terms in this Warrant shall have the
meanings set forth in Section 16. This Warrant is one of the Warrants to
Purchase Common Stock (the “SPA

Purchase Agreement, dated as of November 23, 2009, by and among the Company and
the investors (the “Buyers”) referred to therein
(the “Securities Purchase
Agreement”).

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      
        	
                1.

              	
                EXERCISE OF
      WARRANT.

              


      


      (a)           Mechanics of
Exercise. Subject
to the terms and conditions hereof (including, without limitation, the
limitations set forth in Section 1(f)), this Warrant may be exercised by the
Holder on any day on or after the Issuance Date, in whole or in part, by
delivery (whether via facsimile or otherwise) of a written notice, in the form
attached hereto as Exhibit
A (the “Exercise
Notice”), of the Holder’s election to exercise this Warrant. Within one
(1) Trading Day following an exercise of this Warrant as aforesaid, the Holder
shall deliver payment to the Company of an amount equal to the Exercise Price in
effect on the date of such exercise multiplied by the number of Warrant Shares
as to which this Warrant was so exercised (the “Aggregate Exercise Price”) in
cash or via wire transfer of immediately available funds if the Holder did not
notify the Company in such Exercise Notice that such exercise was made pursuant
to a Cashless Exercise (as defined in Section 1(d)). The Holder shall not be
required to deliver the original of this Warrant in order to effect an exercise
hereunder. Execution and delivery of an Exercise Notice with respect to less
than all of the Warrant Shares shall have the same effect as cancellation of the
original of this Warrant and issuance of a new Warrant evidencing the right to
purchase the remaining number of Warrant Shares. Execution and delivery of an
Exercise Notice for all of the then-remaining Warrant Shares shall have the same
effect as cancellation of the original of this Warrant after delivery of the
Warrant Shares in accordance with the terms hereof. On or before the second
(2nd)
Trading Day following the date on which the Company has received an Exercise
Notice, the Company shall transmit by facsimile an acknowledgment of
confirmation of receipt of such Exercise Notice to the Holder and the Company’s
transfer agent (the “Transfer
Agent”). On or before the third (3rd)
Trading Day following the date on which the Company has received such Exercise
Notice, the Company shall (X) provided that the Transfer Agent is participating
in The Depository Trust Company (“DTC”) Fast Automated
Securities Transfer Program, upon the request of the Holder, credit such
aggregate number of shares of Common Stock to which the Holder is entitled
pursuant to such exercise to the Holder’s or its designee’s balance account with
DTC through its Deposit/ Withdrawal at Custodian system, or (Y) if the Transfer
Agent is not participating in the DTC Fast Automated Securities Transfer
Program, issue and deliver to the Holder or, at the Holder’s instruction
pursuant to the Exercise Notice, the Holder’s agent or designee, in each case,
sent by reputable overnight courier to the address as specified in the
applicable Exercise Notice, a certificate, registered in the Company’s share
register in the name of the Holder or its designee (as indicated in the
applicable Exercise Notice), for the number of shares of Common Stock to which
the Holder is entitled pursuant to such exercise. Upon delivery of an Exercise
Notice, the Holder shall be deemed for all corporate purposes to have become the
holder of record of the Warrant Shares with respect to which this Warrant has
been exercised, irrespective of the date such Warrant Shares are credited to the
Holder’s DTC account or the date of delivery of the certificates evidencing such
Warrant Shares (as the case may be). If this Warrant is submitted in connection
with any exercise pursuant to this Section 1(a) and the number of Warrant Shares
represented by this Warrant submitted for exercise is greater than the number of
Warrant Shares being acquired upon an exercise, then, at the request of the
Holder. the Company shall as soon as practicable and in no event later than five
(5) Business Days after any exercise and at its own expense, issue and deliver
to the Holder (or its designee) a new Warrant (in accordance with Section 7(d))
representing the right to purchase the number of Warrant Shares purchasable
immediately prior to such exercise under this Warrant, less the number of
Warrant Shares with respect to which this Warrant is exercised. No fractional
shares of Common Stock are to be issued upon the exercise of this Warrant, but
rather the number of shares of Common Stock to be issued shall be rounded up to
the nearest whole number. The Company shall pay any and all taxes which may be
payable with respect to the issuance and delivery of Warrant Shares upon
exercise of this Warrant.

       

      (b)           Exercise
Price. For
purposes of this Warrant, “Exercise Price” means $0.30,
subject to adjustment as provided herein.


      
        
           


        

        
          2

          
            

          

        

        
           


        

      

       

      (c)           Company’s Failure to Timely
Deliver Securities. If the
Company shall fail, for any reason or for no reason, to issue to the Holder
within five (5) Trading Days after receipt of the applicable Exercise Notice, a
certificate for the number of shares of Common Stock to which the Holder is
entitled and register such shares of Common Stock on the Company’s share
register or to credit the Holder’s balance account with DTC for such number of
shares of Common Stock to which the Holder is entitled upon the Holder’s
exercise of this Warrant (as the case may be) (a “Delivery Failure”), then, in
addition to all other remedies available to the Holder, the Company shall pay in
cash to the Holder on each day after such fifth (5th)
Trading Day that the issuance of such shares of Common Stock is not timely
effected an amount equal to 2% of the product of (A) the aggregate number of
shares of Common Stock not issued to the Holder on a timely basis and to which
the Holder is entitled and (B) the Closing Sale Price of the Common Stock on the
Trading Day immediately preceding the last possible date on which the Company
could have issued such shares of Common Stock to the Holder without violating
Section 1(a). In addition to the foregoing, if within three (3) Trading Days
after the Company’s receipt of the applicable Exercise Notice, the Company shall
fail to issue and deliver a certificate to the Holder and register such shares
of Common Stock on the Company’s share register or credit the Holder’s balance
account with DTC for the number of shares of Common Stock to which the Holder is
entitled upon the Holder’s exercise hereunder (as the case may be), and if on or
after such third (3rd)
Trading Day the Holder purchases (in an open market transaction or otherwise)
shares of Common Stock to deliver in satisfaction of a sale by the Holder of
shares of Common Stock issuable upon such exercise that the Holder anticipated
receiving from the Company, then, in addition to all other remedies available to
the Holder, the Company shall, within three (3) Business Days after the Holder’s
request and in the Holder’s discretion, either (i) pay cash to the Holder in an
amount equal to the Holder’s total purchase price (including brokerage
commissions, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point
the Company’s obligation to deliver such certificate or credit the Holder’s
balance account with DTC for the number of shares of Common Stock to which the
Holder is entitled upon the Holder’s exercise hereunder (as the case may be)
(and to issue such shares of Common Stock) shall terminate, or (ii) promptly
honor its obligation to deliver to the Holder a certificate or certificates
representing such shares of Common Stock or credit the Holder’s balance account
with DTC for the number of shares of Common Stock to which the Holder is
entitled upon the Holder’s exercise hereunder (as the case may be) and pay cash
to the Holder in an amount equal to the excess (if any) of the Buy-In Price over
the product of (A) such number of shares of Common Stock times (B) the Closing
Sale Price of the Common Stock on the Trading Day immediately preceding the date
of the applicable Exercise Notice.

       

      (d)           Cashless
Exercise.
Notwithstanding anything contained herein to the contrary (other than Section
1(f) below), if at the time of exercise hereof a Registration Statement (as
defined in the Registration Rights Agreement (as defined in the Securities
Purchase Agreement)) is not effective (or the prospectus contained therein is
not available for use) for the resale by the Holder of all of the Warrant
Shares, then the Holder may, in its sole discretion, exercise this Warrant in
whole or in part and, in lieu of making the cash payment otherwise contemplated
to be made to the Company upon such exercise in payment of the Aggregate
Exercise Price, elect instead to receive upon such exercise the “Net Number” of
shares of Common Stock determined according to the following formula (a “Cashless
Exercise”):

       

      Net Number = (A x B) - (A x
C)


       B

       

      
        
          
          

        

        
          3

          
            

          

        

        
          
          

        

      

       

      For purposes of the foregoing
formula:

       

      A= the
total number of shares with respect to which this Warrant is then being
exercised.

       

      B= as
applicable: (i) the Closing Sale Price of the Common Stock on the Trading Day
immediately preceding the date of the applicable Exercise Notice if such
Exercise Notice is (1) both executed and delivered pursuant to Section 1(a)
hereof on a day that is not a Trading Day or (2) both executed and delivered
pursuant to Section 1(a) hereof on a Trading Day prior to the opening of
“regular trading hours” (as defined in Rule 600(b)(64) of Regulation NMS
promulgated under the federal securities laws) on such Trading Day, (ii) the Bid
Price of the Common Stock as of the time of the Holder’s execution of the
applicable Exercise Notice if such Exercise Notice is executed during “regular
trading hours” on a Trading Day and is delivered within two (2) hours thereafter
pursuant to Section 1(a) hereof and (iii) the Closing Sale Price of the Common
Stock on the date of the applicable Exercise Notice if the date of such Exercise
Notice is a Trading Day and such Exercise Notice is both executed and delivered
pursuant to Section 1(a) hereof after the close of “regular trading hours” on
such Trading Day.

       

      
        	
                 
      

              	
                C=
      the Exercise Price then in effect for the applicable Warrant Shares at the
      time of such exercise.

              


      

       

      (e)           Disputes.  In
the case of a dispute as to the determination of the Exercise Price or the
arithmetic calculation of the number of Warrant Shares to be issued pursuant to
the terms hereof (including, without limitation, under Section 1(h)), the
Company shall promptly issue to the Holder the number of Warrant Shares that are
not disputed and resolve such dispute in accordance with Section
13.

       

      (f)           Limitations on
Exercises.  Notwithstanding anything to the contrary contained
in this Warrant, this Warrant shall not be exercisable by the Holder hereof to
the extent (but only to the extent) that the Holder or any of its affiliates
would beneficially own in excess of  4.9% (the “Maximum Percentage”) of the
Common Stock. To the extent the above limitation applies, the determination
of whether this Warrant shall be exercisable (vis-à-vis other convertible,
exercisable or exchangeable securities owned by the Holder) and of which such
securities shall be exercisable (as among all such securities owned by the
Holder or any of its affiliates) shall, subject to such Maximum Percentage
limitation, be determined on the basis of the first submission to the Company
for conversion, exercise or exchange (as the case may be). No prior inability to
exercise this Warrant pursuant to this paragraph shall have any effect on the
applicability of the provisions of this paragraph with respect to any
subsequent determination of exercisability. For the purposes of this paragraph,
beneficial ownership and all determinations and calculations (including, without
limitation, with respect to calculations of percentage ownership) shall be
determined in accordance with Section 13(d) of the 1934 Act (as defined in the
Securities Purchase Agreement) and the rules and regulations promulgated
thereunder. The provisions of this paragraph shall be implemented in a manner
otherwise than in strict conformity with the terms of this paragraph to correct
this paragraph (or any portion hereof) which may be defective or inconsistent
with the intended Maximum Percentage beneficial ownership limitation herein
contained or to make changes or supplements necessary or desirable to properly
give effect to such Maximum Percentage limitation. The limitations contained in
this paragraph shall apply to a successor Holder of this Warrant. The holders of
Common Stock shall be third party beneficiaries of this paragraph and the
Company may not waive this paragraph without the consent of holders of a
majority of its Common Stock. For any reason at any time, upon the written or
oral request of the Holder, the Company shall within one (1) Business Day
confirm orally and in writing to the Holder the number of shares of Common Stock
then outstanding, including by virtue of any prior conversion or exercise of
convertible or exercisable securities into Common Stock, including, without
limitation, pursuant to this Warrant or securities issued pursuant to the
Securities Purchase Agreement.


      
        
           


        

        
          4

          
            

          

        

        
           


        

      

       

      (g)           Insufficient Authorized
Shares. The
Company shall at all times keep reserved for issuance under this Warrant a
number of shares of Common Stock as shall be necessary to satisfy the Company’s
obligation to issue shares of Common Stock hereunder (without regard to any
limitation otherwise contained herein with respect to the number of shares of
Common Stock that may be acquirable upon exercise of this Warrant). If,
notwithstanding the foregoing, and not in limitation thereof, at any time while
any of the SPA Warrants remain outstanding the Company does not have a
sufficient number of authorized and unreserved shares of Common Stock to satisfy
its obligation to reserve for issuance upon exercise of the SPA Warrants at
least a number of shares of Common Stock equal to the number of shares of Common
Stock as shall from time to time be necessary to effect the exercise of all of
the SPA Warrants then outstanding (the “Required Reserve Amount”) (an
“Authorized Share
Failure”), then the Company shall immediately take all action necessary
to increase the Company’s authorized shares of Common Stock to an amount
sufficient to allow the Company to reserve the Required Reserve Amount for all
the SPA Warrants then outstanding. Without limiting the generality of the
foregoing sentence, as soon as practicable after the date of the occurrence of
an Authorized Share Failure, but in no event later than sixty (60) days after
the occurrence of such Authorized Share Failure, the Company shall hold a
meeting of its stockholders for the approval of an increase in the number of
authorized shares of Common Stock. In connection with such meeting, the Company
shall provide each stockholder with a proxy statement and shall use its best
efforts to solicit its stockholders’ approval of such increase in authorized
shares of Common Stock and to cause its board of directors to recommend to the
stockholders that they approve such proposal.

       

      (h)           Issuance
Limit.
Notwithstanding anything to the contrary contained in this Warrant
(but subject to Section 1(f)), the maximum number of Warrant Shares for which
this Warrant may be exercised at any specific time by the Holder shall be equal
to the quotient of (i) the Current Available Amount as of such time over (ii)
the Exercise Price then in effect as of such time. The foregoing determination
shall be made upon each receipt of an Exercise Notice hereunder and no inability
to exercise as of any specific time as a result of this Section 1(h) shall
affect any future determination of exercisability as of any other time. In the
event that the Holder shall sell or otherwise transfer all or any portion of
this Warrant, the Company’s board of directors shall in good faith make
equitable adjustments with respect to the Current Available Amount (and the
components thereof) to properly give effect to such sale of transfer, provided
further that if the Holder does not accept such adjustments, then the Company’s
board of directors and the Holder shall agree, in good faith, upon an
independent investment bank of nationally recognized standing to make such
appropriate adjustments, whose determination shall be final and binding and
whose fees and expenses shall be borne by the Company.

       

      
        
          
          

        

        
          5

          
            

          

        

        
          
          

        

      

       

      2.           ADJUSTMENT
OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and number
of Warrant Shares issuable upon exercise of this Warrant are subject to
adjustment from time to time as set forth in this Section 2.

       

      (a)           Stock Dividends and
Splits.  Without
limiting any provision of Section 4, if the Company, at any time on or after the
date of the Securities Purchase Agreement, (i) pays a stock dividend on one or
more classes of its then outstanding shares of Common Stock or otherwise makes a
distribution on any class of capital stock that is payable in shares of Common
Stock, (ii) subdivides (by any stock split, stock dividend, recapitalization or
otherwise) one or more classes of its then outstanding shares of Common Stock
into a larger number of shares or (iii) combines (by combination, reverse stock
split or otherwise) one or more classes of its then outstanding shares of Common
Stock into a smaller number of shares, then in each such case the Exercise Price
shall be multiplied by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding immediately before such event and of which
the denominator shall be the number of shares of Common Stock outstanding
immediately after such event.  Any adjustment made pursuant to clause
(i) of this paragraph shall become effective immediately after the record date
for the determination of stockholders entitled to receive such dividend or
distribution, and any adjustment pursuant to clause (ii) or (iii) of this
paragraph shall become effective immediately after the effective date of such
subdivision or combination. If any event requiring an adjustment under this
paragraph occurs during the period that an Exercise Price is calculated
hereunder, then the calculation of such Exercise Price shall be adjusted
appropriately to reflect such event.

       

      (b)           Adjustment Upon Issuance of
Shares of Common Stock. If and
whenever on or after the date of the Securities Purchase Agreement, the Company
issues or sells, or in accordance with this Section 2 is deemed to have issued
or sold, any shares of Common Stock (including the issuance or sale of shares of
Common Stock owned or held by or for the account of the Company, but excluding
any Excluded Securities (as defined in the Securities Purchase Agreement) issued
or sold or deemed to have been issued or sold) for a consideration per share
(the “New Issuance
Price”) less than a price equal to the Exercise Price in effect
immediately prior to such issue or sale or deemed issuance or sale (such
Exercise Price then in effect is referred to as the “Applicable Price”) (the
foregoing a “Dilutive
Issuance”), then immediately after such Dilutive Issuance, the Exercise
Price then in effect shall be reduced to an amount equal to the New Issuance
Price. For purposes of determining the adjusted Exercise Price under this
Section 2(b), the following shall be applicable:


      
        
           


        

        
          6

          
            

          

        

        
           


        

      


      (i)           Issuance of
Options.  If the Company in any manner grants or sells any
Options and the lowest price per share for which one share of Common Stock is
issuable upon the exercise of any such Option or upon conversion, exercise or
exchange of any Convertible Securities issuable upon exercise of any such Option
is less than the Applicable Price, then such share of Common Stock shall be
deemed to be outstanding and to have been issued and sold by the Company at the
time of the granting or sale of such Option for such price per share. For
purposes of this Section 2(b)(i), the “lowest price per share for which one
share of Common Stock is issuable upon the exercise of any such Options or upon
conversion, exercise or exchange of any Convertible Securities issuable upon
exercise of any such Option” shall be equal to (1) the lower of (x) the sum of
the lowest amounts of consideration (if any) received or receivable by the
Company with respect to any one share of Common Stock upon the granting or sale
of such Option, upon exercise of such Option and upon conversion, exercise or
exchange of any Convertible Security issuable upon exercise of such Option and
(y) the lowest exercise price set forth in such Option for which one share of
Common Stock is issuable upon the exercise of any such Options or upon
conversion, exercise or exchange of any Convertible Securities issuable upon
exercise of any such Option minus (2) the sum of all amounts paid or payable to
the holder of such Option (or any other Person) upon the granting or sale of
such Option, upon exercise of such Option and upon conversion, exercise or
exchange of any Convertible Security issuable upon exercise of such Option plus
the value of any other consideration received or receivable by, or benefit
conferred on, the holder of such Option (or any other Person). Except as
contemplated below, no further adjustment of the Exercise Price shall be made
upon the actual issuance of such shares of Common Stock or of such Convertible
Securities upon the exercise of such Options or upon the actual issuance of such
shares of Common Stock upon conversion, exercise or exchange of such Convertible
Securities.

       

      (ii)           Issuance of Convertible
Securities.  If the Company in any manner issues or sells any
Convertible Securities and the lowest price per share for which one share of
Common Stock is issuable upon the conversion, exercise or exchange thereof is
less than the Applicable Price, then such share of Common Stock shall be deemed
to be outstanding and to have been issued and sold by the Company at the time of
the issuance or sale of such Convertible Securities for such price per
share.  For the purposes of this Section 2(b)(ii), the “lowest price
per share for which one share of Common Stock is issuable upon the conversion,
exercise or exchange thereof” shall be equal to (1) the lower of (x) the sum of
the lowest amounts of consideration (if any) received or receivable by the
Company with respect to one share of Common Stock upon the issuance or sale of
the Convertible Security and upon conversion, exercise or exchange of such
Convertible Security and (y) the lowest conversion price set forth in such
Convertible Security for which one share of Common Stock is issuable upon
conversion, exercise or exchange thereof minus (2) the sum of all amounts paid
or payable to the holder of such Convertible Security (or any other Person) upon
the issuance or sale of such Convertible Security plus the value of any other
consideration received or receivable by, or benefit conferred on, the holder of
such Convertible Security (or any other Person). Except as contemplated below,
no further adjustment of the Exercise Price shall be made upon the actual
issuance of such shares of Common Stock upon conversion, exercise or exchange of
such Convertible Securities, and if any such issue or sale of such Convertible
Securities is made upon exercise of any Options for which adjustment of this
Warrant has been or is to be made pursuant to other provisions of this Section
2(b), except as contemplated below, no further adjustment of the Exercise Price
shall be made by reason of such issue or sale.


      
        
           


        

        
          7

          
            

          

        

        
           


        

      


      (iii)           Change in Option Price or
Rate of Conversion. If the purchase or exercise price provided for in any
Options, the additional consideration, if any, payable upon the issue,
conversion, exercise or exchange of any Convertible Securities, or the rate at
which any Convertible Securities are convertible into or exercisable or
exchangeable for shares of Common Stock increases or decreases at any time, the
Exercise Price in effect at the time of such increase or decrease shall be
adjusted to the Exercise Price which would have been in effect at such time had
such Options or Convertible Securities provided for such increased or decreased
purchase price, additional consideration or increased or decreased conversion
rate, as the case may be, at the time initially granted, issued or sold. For
purposes of this Section 2(b)(iii), if the terms of any Option or Convertible
Security that was outstanding as of the date of issuance of this Warrant are
increased or decreased in the manner described in the immediately preceding
sentence, then such Option or Convertible Security and the shares of Common
Stock deemed issuable upon exercise, conversion or exchange thereof shall be
deemed to have been issued as of the date of such increase or decrease. No
adjustment pursuant to this Section 2(b) shall be made if such adjustment would
result in an increase of the Exercise Price then in effect.

       

      (iv)           Calculation of Consideration
Received. If any Option or Convertible Security is issued in connection
with the issuance or sale or deemed issuance or sale of any other securities of
the Company, together comprising one integrated transaction, (x) such Option or
Convertible Security (as applicable) will be deemed to have been issued for
consideration equal to the Black Scholes Consideration Value thereof and (y) the
other securities issued or sold or deemed to have been issued or sold in such
integrated transaction shall be deemed to have been issued for consideration
equal to the difference of (I) the aggregate consideration received by the
Company minus (II) the Black Scholes Consideration Value of each such Option or
Convertible Security (as applicable).  If any shares of Common Stock,
Options or Convertible Securities are issued or sold or deemed to have been
issued or sold for cash, the consideration received therefor will be deemed to
be the net amount of consideration received by the Company therefor. If any
shares of Common Stock, Options or Convertible Securities are issued or sold for
a consideration other than cash, the amount of such consideration received by
the Company will be the fair value of such consideration, except where such
consideration consists of publicly traded securities, in which case the amount
of consideration received by the Company for such securities will be the
arithmetic average of the VWAPs of such security for each of the five (5)
Trading Days immediately preceding the date of receipt. If any shares of Common
Stock, Options or Convertible Securities are issued to the owners of the
non-surviving entity in connection with any merger in which the Company is the
surviving entity, the amount of consideration therefor will be deemed to be the
fair value of such portion of the net assets and business of the non-surviving
entity as is attributable to such shares of Common Stock, Options or Convertible
Securities, as the case may be. The fair value of any consideration other than
cash or publicly traded securities will be determined jointly by the Company and
the Holder. If such parties are unable to reach agreement within ten (10) days
after the occurrence of an event requiring valuation (the “Valuation Event”), the fair
value of such consideration will be determined within five (5) Trading Days
after the tenth (10th) day
following such Valuation Event by an independent, reputable appraiser jointly
selected by the Company and the Holder. The determination of such appraiser
shall be final and binding upon all parties absent manifest error and the fees
and expenses of such appraiser shall be borne by the Company.

      (v)           Record Date. If the
Company takes a record of the holders of shares of Common Stock for the purpose
of entitling them (A) to receive a dividend or other distribution payable
in shares of Common Stock, Options or in Convertible Securities or (B) to
subscribe for or purchase shares of Common Stock, Options or Convertible
Securities, then such record date will be deemed to be the date of the issue or
sale of the shares of Common Stock deemed to have been issued or sold upon the
declaration of such dividend or the making of such other distribution or the
date of the granting of such right of subscription or purchase (as the case may
be).

       

      (c)           Number of Warrant
Shares.
Simultaneously with any adjustment to the Exercise Price pursuant to paragraphs
(a) or (b) of this Section 2, the number of Warrant Shares that may be purchased
upon exercise of this Warrant shall be increased or decreased proportionately,
so that after such adjustment the aggregate Exercise Price payable hereunder for
the adjusted number of Warrant Shares shall be the same as the aggregate
Exercise Price in effect immediately prior to such adjustment (without regard to
any limitations on exercise contained herein).

       

      (d)           Other
Events. In the
event that the Company (or any Subsidiary) shall take any action to which the
provisions hereof are not strictly applicable, or, if applicable, would not
operate to protect the Holder from dilution or if any event occurs of the type
contemplated by the provisions of this Section 2 but not expressly provided for
by such provisions (including, without limitation, the granting of stock
appreciation rights, phantom stock rights or other rights with equity features),
then the Company’s board of directors shall in good faith determine and
implement an appropriate adjustment in the Exercise Price and the number of
Warrant Shares (if applicable) so as to protect the rights of the Holder,
provided that no such adjustment pursuant to this Section 2(d) will increase the
Exercise Price or decrease the number of Warrant Shares as otherwise determined
pursuant to this Section 2, provided further that if the Holder does not accept
such adjustments as appropriately protecting its interests hereunder against
such dilution, then the Company’s board of directors and the Holder shall agree,
in good faith, upon an independent investment bank of nationally recognized
standing to make such appropriate adjustments, whose determination shall be
final and binding and whose fees and expenses shall be borne by the
Company.

       

      (e)           Calculations. All
calculations under this Section 2 shall be made to the nearest cent or the
nearest 1/100th of a
share, as applicable. The number of shares of Common Stock outstanding at any
given time shall not include shares owned or held by or for the account of the
Company, and the disposition of any such shares shall be considered an issue or
sale of Common Stock.

       

      3.           RIGHTS UPON DISTRIBUTION OF
ASSETS. In addition to any adjustments pursuant to Section 2 above, if
the Company shall declare or make any dividend or other distribution of its
assets (or rights to acquire its assets) to holders of shares of Common Stock,
by way of return of capital or otherwise (including, without limitation, any
distribution of cash, stock or other securities, property or options by way of a
dividend, spin off, reclassification, corporate rearrangement, scheme of
arrangement or other similar transaction) (a “Distribution”), at any time
after the issuance of this Warrant, then, in each such case, the Holder shall be
entitled to participate in such Distribution to the same extent that the Holder
would have participated therein if the Holder had held the number of shares of
Common Stock acquirable upon complete exercise of this Warrant (without regard
to any limitations on exercise hereof, including without limitation, the Maximum
Percentage) immediately before the date on which a record is taken for such
Distribution, or, if no such record is taken, the date as of which the record
holders of shares of Common Stock are to be determined for the participation in
such Distribution (provided, however, to the extent that the Holder’s right to
participate in any such Distributions would result in the Holder exceeding the
Maximum Percentage, then the Holder shall not be entitled to participate in such
Distribution to such extent (or the beneficial ownership of any such shares of
Common Stock as a result of such Distribution to such extent) and such
Distribution to such extent shall be held in abeyance for the benefit of the
Holder until such time, if ever, as its right thereto would not result in the
Holder exceeding the Maximum Percentage).

      (a)           Purchase
Rights.  In
addition to any adjustments pursuant to Section 2 above, if at any time the
Company grants, issues or sells any Options, Convertible Securities or rights to
purchase stock, warrants, securities or other property pro rata to the record
holders of any class of shares of Common Stock (the “Purchase Rights”), then the
Holder will be entitled to acquire, upon the terms applicable to such Purchase
Rights, the aggregate Purchase Rights which the Holder could have acquired if
the Holder had held the number of shares of Common Stock acquirable upon
complete exercise of this Warrant (without regard to any limitations on exercise
hereof, including without limitation, the Maximum Percentage) immediately before
the date on which a record is taken for the grant, issuance or sale of such
Purchase Rights, or, if no such record is taken, the date as of which the record
holders of shares of Common Stock are to be determined for the grant, issue or
sale of such Purchase Rights (provided, however, to the extent that the Holder’s
right to participate in any such Purchase Right would result in the Holder
exceeding the Maximum Percentage, then the Holder shall not be entitled to
participate in such Purchase Right to such extent (or beneficial ownership of
such shares of Common Stock as a result of such Purchase Right to such extent)
and such Purchase Right to such extent shall be held in abeyance for the Holder
until such time, if ever, as its right thereto would not result in the Holder
exceeding the Maximum Percentage).

      (b)           Fundamental
Transactions.  The
Company shall not enter into or be party to a Fundamental Transaction unless
(i)  the Successor Entity assumes in writing all of the obligations of the
Company under this Warrant and the other Transaction Documents (as defined in
the Securities Purchase Agreement) in accordance with the provisions of this
Section 4(b) pursuant to written agreements in form and substance satisfactory
to the Holder and approved by the Holder prior to such Fundamental Transaction,
including agreements to deliver to the Holder in exchange for this Warrant a
security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to this Warrant, including, without limitation,
which is exercisable for a corresponding number of shares of capital stock
equivalent to the shares of Common Stock acquirable and receivable upon exercise
of this Warrant (without regard to any limitations on the exercise of this
Warrant) prior to such Fundamental Transaction, and with an exercise price which
applies the exercise price hereunder to such shares of capital stock (but taking
into account the relative value of the shares of Common Stock pursuant to such
Fundamental Transaction and the value of such shares of capital stock, such
adjustments to the number of shares of capital stock and such exercise price
being for the purpose of protecting the economic value of this Warrant
immediately prior to the consummation of such Fundamental Transaction) and
(ii) the Successor Entity (including its Parent Entity) is a publicly
traded corporation whose common stock is quoted on or listed for trading on an
Eligible Market. Upon the consummation of each Fundamental Transaction, the
Successor Entity shall succeed to, and be substituted for (so that from and
after the date of the applicable Fundamental Transaction, the provisions of this
Warrant and the other Transaction Documents referring to the “Company” shall
refer instead to the Successor Entity), and may exercise every right and power
of the Company and shall assume all of the obligations of the Company under this
Warrant and the other Transaction Documents with the same effect as if such
Successor Entity had been named as the Company herein. Upon consummation of each
Fundamental Transaction, the Successor Entity shall deliver to the Holder
confirmation that there shall be issued upon exercise of this Warrant at any
time after the consummation of the applicable Fundamental Transaction, in lieu
of the shares of Common Stock (or other securities, cash, assets or other
property (except such items still issuable under Sections 3 and 4(a) above,
which shall continue to be receivable thereafter)) issuable upon the exercise of
this Warrant prior to the applicable Fundamental Transaction, such shares of
publicly traded common stock (or its equivalent) of the Successor Entity
(including its Parent Entity) which the Holder would have been entitled to
receive upon the happening of the applicable Fundamental Transaction had this
Warrant been exercised immediately prior to the applicable Fundamental
Transaction (without regard to any limitations on the exercise of this Warrant),
as adjusted in accordance with the provisions of this Warrant. In addition to
and not in substitution for any other rights hereunder, prior to the
consummation of each Fundamental Transaction pursuant to which holders of shares
of Common Stock are entitled to receive securities or other assets with respect
to or in exchange for shares of Common Stock (a “Corporate Event”), the Company
shall make appropriate provision to insure that the Holder will thereafter have
the right to receive upon an exercise of this Warrant at any time after the
consummation of the applicable Fundamental Transaction but prior to the
Expiration Date, in lieu of the shares of the Common Stock (or other securities,
cash, assets or other property (except such items still issuable under Sections
3 and 4(a) above, which shall continue to be receivable thereafter)) issuable
upon the exercise of the Warrant prior to such Fundamental Transaction, such
shares of stock, securities, cash, assets or any other property whatsoever
(including warrants or other purchase or subscription rights) which the Holder
would have been entitled to receive upon the happening of the applicable
Fundamental Transaction had this Warrant been exercised immediately prior to the
applicable Fundamental Transaction (without regard to any limitations on the
exercise of this Warrant). Provision made pursuant to the preceding sentence
shall be in a form and substance reasonably satisfactory to the
Holder.

       

      (c)           Black Scholes
Value.
Notwithstanding the foregoing and the provisions of Section 4(b) above, in the
event of a Fundamental Transaction, if the Holder has not exercised this Warrant
in full prior to the consummation of such Fundamental Transaction, at the
request of the Holder delivered before the ninetieth (90th) day
after the consummation of such Fundamental Transaction, the Company or the
Successor Entity (as the case may be) shall purchase this Warrant from the
Holder on the date of such request by paying to the Holder cash in an amount
equal to the Black Scholes Value.

       

      (d)           Application. The
provisions of this Section 4 shall apply similarly and equally to successive
Fundamental Transactions and Corporate Events and shall be applied as if this
Warrant (and any such subsequent warrants) were fully exercisable and without
regard to any limitations on the exercise of this Warrant (provided that the
Holder shall continue to be entitled to the benefit of the Maximum Percentage,
applied however with respect to shares of capital stock registered under the
1934 Act and thereafter receivable upon exercise of this Warrant (or any such
other warrant)).

      5.           NONCIRCUMVENTION. The
Company hereby covenants and agrees that the Company will not, by amendment of
its Articles of Incorporation (as defined in the Securities Purchase Agreement),
Bylaws (as defined in the Securities Purchase Agreement) or through any
reorganization, transfer of assets, consolidation, merger, scheme of
arrangement, dissolution, issue or sale of securities, or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the terms
of this Warrant, and will at all times in good faith carry out all the
provisions of this Warrant and take all action as may be required to protect the
rights of the Holder. Without limiting the generality of the foregoing, the
Company (i) shall not increase the par value of any shares of Common Stock
receivable upon the exercise of this Warrant above the Exercise Price then in
effect, (ii) shall take all such actions as may be necessary or appropriate
in order that the Company may validly and legally issue fully paid and
nonassessable shares of Common Stock upon the exercise of this Warrant, and
(iii) shall, so long as any of the SPA Warrants are outstanding, take all action
necessary to reserve and keep available out of its authorized and unissued
shares of Common Stock, solely for the purpose of effecting the exercise of the
SPA Warrants, the maximum number of shares of Common Stock as shall from time to
time be necessary to effect the exercise of the SPA Warrants then outstanding
(without regard to any limitations on exercise).

       

      6.           WARRANT HOLDER NOT DEEMED A
STOCKHOLDER. Except as otherwise specifically provided herein, the
Holder, solely in its capacity as a holder of this Warrant, shall not be
entitled to vote or receive dividends or be deemed the holder of share capital
of the Company for any purpose, nor shall anything contained in this Warrant be
construed to confer upon the Holder, solely in its capacity as the Holder of
this Warrant, any of the rights of a stockholder of the Company or any right to
vote, give or withhold consent to any corporate action (whether any
reorganization, issue of stock, reclassification of stock, consolidation,
merger, conveyance or otherwise), receive notice of meetings, receive dividends
or subscription rights, or otherwise, prior to the issuance to the Holder of the
Warrant Shares which it is then entitled to receive upon the due exercise of
this Warrant.  In addition, nothing contained in this Warrant shall be
construed as imposing any liabilities on the Holder to purchase any securities
(upon exercise of this Warrant or otherwise) or as a stockholder of the Company,
whether such liabilities are asserted by the Company or by creditors of the
Company. Notwithstanding this Section 6, the Company shall provide the Holder
with copies of the same notices and other information given to the stockholders
of the Company generally, contemporaneously with the giving thereof to the
stockholders.

       

      7.           REISSUANCE OF
WARRANTS.

       

      (a)           Transfer of
Warrant. If this
Warrant is to be transferred, the Holder shall surrender this Warrant to the
Company, whereupon the Company will forthwith issue and deliver upon the order
of the Holder a new Warrant (in accordance with Section 7(d)), registered as the
Holder may request, representing the right to purchase the number of Warrant
Shares being transferred by the Holder and, if less than the total number of
Warrant Shares then underlying this Warrant is being transferred, a new Warrant
(in accordance with Section 7(d)) to the Holder representing the right to
purchase the number of Warrant Shares not being transferred.


      
        
           


        

        
          12

          
            

          

        

        
           


        

      

       

      (b)           Lost, Stolen or Mutilated
Warrant. Upon
receipt by the Company of evidence reasonably satisfactory to the Company of the
loss, theft, destruction or mutilation of this Warrant (as to which a written
certification and the indemnification contemplated below shall suffice as such
evidence), and, in the case of loss, theft or destruction, of any
indemnification undertaking by the Holder to the Company in customary and
reasonable form and, in the case of mutilation, upon surrender and cancellation
of this Warrant, the Company shall execute and deliver to the Holder a new
Warrant (in accordance with Section 7(d)) representing the right to purchase the
Warrant Shares then underlying this Warrant.

       

      (c)           Exchangeable for Multiple
Warrants. This
Warrant is exchangeable, upon the surrender hereof by the Holder at the
principal office of the Company, for a new Warrant or Warrants (in accordance
with Section 7(d)) representing in the aggregate the right to purchase the
number of Warrant Shares then underlying this Warrant, and each such new Warrant
will represent the right to purchase such portion of such Warrant Shares as is
designated by the Holder at the time of such surrender; provided, however, no
warrants for fractional shares of Common Stock shall be given.

       

      (d)           Issuance of New
Warrants.
Whenever the Company is required to issue a new Warrant pursuant to the terms of
this Warrant, such new Warrant (i) shall be of like tenor with this Warrant,
(ii) shall represent, as indicated on the face of such new Warrant, the right to
purchase the Warrant Shares then underlying this Warrant (or in the case of a
new Warrant being issued pursuant to Section 7(a) or Section 7(c), the Warrant
Shares designated by the Holder which, when added to the number of shares of
Common Stock underlying the other new Warrants issued in connection with such
issuance, does not exceed the number of Warrant Shares then underlying this
Warrant), (iii) shall have an issuance date, as indicated on the face of such
new Warrant which is the same as the Issuance Date, and (iv) shall have the same
rights and conditions as this Warrant.

       

      8.           NOTICES.  Whenever
notice is required to be given under this Warrant, unless otherwise provided
herein, such notice shall be given in accordance with Section 9(f) of the
Securities Purchase Agreement. The Company shall provide the Holder with prompt
written notice of all actions taken pursuant to this Warrant, including in
reasonable detail a description of such action and the reason therefor. Without
limiting the generality of the foregoing, the Company will give written notice
to the Holder (i) immediately upon each adjustment of the Exercise Price and the
number of Warrant Shares, setting forth in reasonable detail, and certifying,
the calculation of such adjustment(s) and (ii) at least fifteen (15) days prior
to the date on which the Company closes its books or takes a record (A) with
respect to any dividend or distribution upon the shares of Common Stock, (B)
with respect to any grants, issuances or sales of any Options, Convertible
Securities or rights to purchase stock, warrants, securities or other property
to holders of shares of Common Stock or (C) for determining rights to vote with
respect to any Fundamental Transaction, dissolution or liquidation, provided in
each case that such information shall be made known to the public prior to or in
conjunction with such notice being provided to the Holder and (iii) at least ten
(10) Trading Days prior to the consummation of any Fundamental
Transaction.  To the extent that any notice provided hereunder
constitutes, or contains, material, non-public information regarding the Company
or any of its subsidiaries, the Company shall simultaneously file such notice
with the SEC (as defined in the Securities Purchase Agreement) pursuant to a
Current Report on Form 8-K. It is expressly understood and agreed that the time
of execution specified by the Holder in each Exercise Notice shall be definitive
and may not be disputed or challenged by the Company.

      9.           AMENDMENT AND
WAIVER.  Except as otherwise provided herein, the provisions of
this Warrant (other than Section 1(f)) may be amended and the Company may take
any action herein prohibited, or omit to perform any act herein required to be
performed by it, only if the Company has obtained the written consent of the
Holder. The Holder shall be entitled, at its option, to the benefit of any
amendment of (i) any other similar warrant issued under the Securities Purchase
Agreement or (ii) any other similar warrant. No waiver shall be effective unless
it is in writing and signed by an authorized representative of the waiving
party.

       

      10.           SEVERABILITY.  If
any provision of this Warrant or the application thereof becomes or is declared
by a court of competent jurisdiction to be illegal, void or unenforceable, the
remainder of the terms of this Warrant will continue in full force and
effect.

       

      11.           GOVERNING LAW. This
Warrant shall be governed by and construed and enforced in accordance with, and
all questions concerning the construction, validity, interpretation and
performance of this Warrant shall be governed by, the internal laws of the State
of Illinois, without giving effect to any choice of law or conflict of law
provision or rule (whether of the State of Illinois or any other jurisdictions)
that would cause the application of the laws of any jurisdictions other than the
State of Illinois.

       

      12.           CONSTRUCTION;
HEADINGS. This Warrant shall be deemed to be jointly drafted by the
Company and the Holder and shall not be construed against any Person as the
drafter hereof.  The headings of this Warrant are for convenience of
reference and shall not form part of, or affect the interpretation of, this
Warrant. Terms used in this Warrant but defined in the other Transaction
Documents shall have the meanings ascribed to such terms on the Closing Date (as
defined in the Securities Purchase Agreement) in such other Transaction
Documents unless otherwise consented to in writing by the Holder.

       

      13.           DISPUTE RESOLUTION.
In the case of a dispute as to the determination of the Exercise Price, the
Closing Sale Price, the Bid Price or fair market value or the arithmetic
calculation of the Warrant Shares (as the case may be), the Company or the
Holder (as the case may be) shall submit the disputed determinations or
arithmetic calculations (as the case may be) via facsimile (i) within two (2)
Business Days after receipt of the applicable notice giving rise to such dispute
to the Company or the Holder (as the case may be) or (ii) if no notice gave rise
to such dispute, at any time after the Holder learned of the circumstances
giving rise to such dispute (including, without limitation, as to whether any
issuance or sale or deemed issuance or sale was an issuance or sale or deemed
issuance or sale of Excluded Securities). If the Holder and the Company are
unable to agree upon such determination or calculation (as the case may be) of
the Exercise Price, the Closing Sale Price, the Bid Price or fair market value
or the number of Warrant Shares (as the case may be) within three (3) Business
Days of such disputed determination or arithmetic calculation being submitted to
the Company or the Holder (as the case may be), then the Company shall, within
two (2) Business Days submit via facsimile (a) the disputed determination of the
Exercise Price, the Closing Sale Price, the Bid Price or fair market value (as
the case may be) to an independent, reputable investment bank selected by the
Company and approved by the Holder or (b) the disputed arithmetic calculation of
the Warrant Shares to the Company’s independent, outside accountant. The Company
shall cause at its expense the investment bank or the accountant (as the case
may be) to perform the determinations or calculations (as the case may be) and
notify the Company and the Holder of the results no later than ten (10) Business
Days from the time it receives such disputed determinations or calculations (as
the case may be). Such investment bank’s or accountant’s determination or
calculation (as the case may be) shall be binding upon all parties absent
demonstrable error.

      14.           REMEDIES, CHARACTERIZATION,
OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided
in this Warrant shall be cumulative and in addition to all other remedies
available under this Warrant and the other Transaction Documents, at law or in
equity (including a decree of specific performance and/or other injunctive
relief), and nothing herein shall limit the right of the Holder to pursue actual
damages for any failure by the Company to comply with the terms of this Warrant.
The Company covenants to the Holder that there shall be no characterization
concerning this instrument other than as expressly provided herein. Amounts set
forth or provided for herein with respect to payments, exercises and the like
(and the computation thereof) shall be the amounts to be received by the Holder
and shall not, except as expressly provided herein, be subject to any other
obligation of the Company (or the performance thereof). The Company acknowledges
that a breach by it of its obligations hereunder will cause irreparable harm to
the Holder and that the remedy at law for any such breach may be inadequate. The
Company therefore agrees that, in the event of any such breach or threatened
breach, the holder of this Warrant shall be entitled, in addition to all other
available remedies, to an injunction restraining any breach, without the
necessity of showing economic loss and without any bond or other security being
required. The Company shall provide all information and documentation to the
Holder that is requested by the Holder to enable the Holder to confirm the
Company’s compliance with the terms and conditions of this Warrant (including,
without limitation, compliance with Section 2 hereof). The issuance of shares
and certificates for shares as contemplated hereby upon the exercise of this
Warrant shall be made without charge to the Holder or such shares for any
issuance tax or other costs in respect thereof, provided that the Company shall
not be required to pay any tax which may be payable in respect of any transfer
involved in the issuance and delivery of any certificate in a name other than
the Holder or its agent on its behalf.

       

      15.           TRANSFER. This
Warrant may be offered for sale, sold, transferred or assigned without the
consent of the Company, except as may otherwise be required by Section 2(g) of
the Securities Purchase Agreement.

       

      16.           CERTAIN
DEFINITIONS.  For purposes of this Warrant, the following terms
shall have the following meanings:

       

       
(a)           “Aggregate Face Exercise
Amount” is equal to $1,125,000.50.

       

       
(b)           “Aggregate Series B Face Exercise
Amount” is equal to $900,000.40.
