    THIS
COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies
that, for value received, _____________ (the “Holder”) is entitled,
upon the terms and subject to the limitations on exercise and the conditions
hereinafter set forth, at any time on or after the date hereof (the “Initial Exercise
Date”) and on or prior to the close of business on the five year
anniversary of the Initial Exercise Date (the “Termination Date”)
but not thereafter, to subscribe for and purchase from GenSpera, Inc., a
Delaware corporation (the “Company”), up to
______ shares (the “Warrant Shares”) of
Common Stock.  The purchase price of one share of Common Stock under
this Warrant shall be equal to the Exercise Price, as defined in Section
2(b).

     

    Section
1.       Definitions.  Capitalized
terms used and not otherwise defined herein shall have the meanings set forth in
that certain Securities Purchase Agreement (the “Purchase Agreement”),
dated September ___, 2009, among the Company and the purchasers signatory
thereto.

    Section
2.       Exercise.

     

    a)         Exercise of
Warrant.  Exercise of the purchase rights represented by this
Warrant may be made, in whole or in part, at any time or times on or after the
Initial Exercise Date and on or before the Termination Date by delivery to the
Company (or such other office or agency of the Company as it may designate by
notice in writing to the registered Holder at the address of the Holder
appearing on the books of the Company) of a duly executed facsimile copy of the
Notice of Exercise Form annexed hereto; and, within 3 Business Days of the date
said Notice of Exercise is delivered to the Company, the Company shall have
received  payment of the aggregate Exercise Price of the shares
thereby purchased by wire transfer or cashier’s check drawn on a United States
bank.  Notwithstanding anything herein to the contrary, the Holder
shall not be required to physically surrender this Warrant to the Company until
the Holder has purchased all of the Warrant Shares available hereunder and the
Warrant has been exercised in full, in which case, the Holder shall surrender
this Warrant to the Company for cancellation within 3 Business Days of the date
the final Notice of Exercise is delivered to the Company.  Partial
exercises of this Warrant resulting in purchases of a portion of the total
number of Warrant Shares available hereunder shall have the effect of lowering
the outstanding number of Warrant Shares purchasable hereunder in an amount
equal to the applicable number of Warrant Shares purchased.  The
Holder and the Company shall maintain records showing the number of Warrant
Shares purchased and the date of such purchases.  The Company shall
deliver any objection to any Notice of Exercise Form within 1 Business Day of
receipt of such notice.  In the event of any dispute or discrepancy,
the records of the Holder shall be controlling and determinative in the absence
of manifest error. The Holder
and any assignee, by acceptance of this Warrant, acknowledge and agree that, by
reason of the provisions of this paragraph, following the purchase of a portion
of the Warrant Shares hereunder, the number of Warrant Shares available for
purchase hereunder at any given time may be less than the amount stated on the
face hereof.

     

    b)         Exercise
Price.  The exercise price per share of the Common Stock under
this Warrant shall be $3.00,
subject to adjustment hereunder (the “Exercise
Price”).

     

    c)         Cashless
Exercise.  If at any time after the earlier of (i) the one year
anniversary of the date of the Purchase Agreement and (ii) the completion of the
then-applicable holding period required by Rule 144, or any successor provision
then in effect, there is no effective Registration Statement registering, or no
current prospectus available for, the resale of the Warrant Shares by the
Holder, then this Warrant may also be exercised at such time by means of a
“cashless exercise” in which the Holder shall be entitled to receive a
certificate for the number of Warrant Shares equal to the quotient obtained by
dividing [(A-B) (X)] by (A), where:

     

    
      (A)
=  the VWAP on the Business Day immediately preceding the date of such
election;

    

    


    
      (B)
=  the Exercise Price of this Warrant, as adjusted; and

    

    


    
      (X)
=  the number of Warrant Shares issuable upon exercise of this Warrant in
accordance with the terms of this Warrant by means of a cash exercise rather
than a cashless exercise.

    


    
      
         


      

      
        2

        
          

        

      

      
         


      

    

     

    Notwithstanding
anything herein to the contrary, on the Termination Date, this Warrant shall be
automatically exercised via cashless exercise pursuant to this Section
2(c).

    


    d)         Exercise Limitations.
The Company shall not effect any exercise of this Warrant, and a Holder shall
not have the right to exercise any portion of this Warrant, pursuant to Section
2 or otherwise, to the extent that after giving effect to such issuance after
exercise as set forth on the applicable Notice of Exercise, the Holder (together
with the Holder’s Affiliates, and any other person or entity acting as a group
together with the Holder or any of the Holder’s Affiliates), would beneficially
own in excess of the Beneficial Ownership Limitation (as defined below). 
For purposes of the foregoing sentence, the number of shares of Common Stock
beneficially owned by the Holder and its Affiliates shall include the number of
shares of Common Stock issuable upon exercise of this Warrant with respect to
which such determination is being made, but shall exclude the number of shares
of Common Stock which would be issuable upon (A) exercise of the remaining,
nonexercised portion of this Warrant beneficially owned by the Holder or any of
its Affiliates and (B) exercise or conversion of the unexercised or nonconverted
portion of any other securities of the Company (including, without limitation,
any other  Common Stock Equivalents) subject to a limitation on
conversion or exercise analogous to the limitation contained herein beneficially
owned by the Holder or any of its affiliates.  Except as set forth in the
preceding sentence, for purposes of this Section 2(d), beneficial ownership
shall be calculated in accordance with Section 13(d) of the Exchange Act and the
rules and regulations promulgated thereunder, it being acknowledged by the
Holder that the Company is not representing to the Holder that such calculation
is in compliance with Section 13(d) of the Exchange Act and the Holder is solely
responsible for any schedules required to be filed in accordance
therewith.   To the extent that the limitation contained in this
Section 2(d) applies, the determination of whether this Warrant is exercisable
(in relation to other securities owned by the Holder together with any
Affiliates) and of which portion of this Warrant is exercisable shall be in the
sole discretion of the Holder, and the submission of a Notice of Exercise shall
be deemed to be the Holder’s determination of whether this Warrant is
exercisable (in relation to other securities owned by the Holder together with
any Affiliates) and of which portion of this Warrant is exercisable, in each
case subject to the Beneficial Ownership Limitation, and the Company shall have
no obligation to verify or confirm the accuracy of such
determination.   In addition, a determination as to any group
status as contemplated above shall be determined in accordance with Section
13(d) of the Exchange Act and the rules and regulations promulgated
thereunder.  For purposes of this Section 2(d), in determining the
number of outstanding shares of Common Stock, a Holder may rely on the number of
outstanding shares of Common Stock as reflected in (A) Schedule 3.1(g) to
the Purchase Agreement, as the case may be, (B) a more recent public
announcement by the Company or (C) any other notice by the Company or the
transfer agent of the Company setting forth the number of shares of Common Stock
outstanding.  Upon the written or oral request of a Holder, the Company
shall within two Business Days confirm orally and in writing to the Holder the
number of shares of Common Stock then outstanding.  In any case, the number
of outstanding shares of Common Stock shall be determined after giving effect to
the conversion or exercise of securities of the Company, including this Warrant,
by the Holder or its Affiliates since the date as of which such number of
outstanding shares of Common Stock was reported.  The “Beneficial Ownership
Limitation” shall be 4.99% of the number of shares of the Common Stock
outstanding immediately after giving effect to the issuance of shares of Common
Stock issuable upon exercise of this Warrant.  The Holder, upon not
less than 61 days’ prior notice to the Company, may increase or decrease the
Beneficial Ownership Limitation provisions of this Section 2(d), provided that
the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of
shares of the Common Stock outstanding immediately after giving effect to the
issuance of shares of Common Stock upon exercise of this Warrant held by the
Holder and the provisions of this Section 2(d) shall continue to
apply.  Any such increase or decrease will not be effective until the
61st
day after such notice is delivered to the Company.  The provisions of
this paragraph shall be construed and implemented in a manner otherwise than in
strict conformity with the terms of this Section 2(d) to correct this paragraph
(or any portion hereof) which may be defective or inconsistent with the intended
Beneficial Ownership Limitation herein contained or to make changes or
supplements necessary or desirable to properly give effect to such limitation.
The limitations contained in this paragraph shall apply to a successor holder of
this Warrant.

    e)        Mechanics of
Exercise.

     

    i.      Delivery of Certificates
Upon Exercise.  Certificates for shares purchased hereunder
shall be transmitted by the transfer agent of the Company to the Holder by
crediting the account of the Holder’s prime broker with the Depository Trust
Company through its Deposit Withdrawal Agent Commission (“DWAC”) system if the
Company is then a participant in such system and either (A) there is an
effective Registration Statement permitting the resale of the Warrant Shares by
the Holder or (B) the shares are eligible for resale without volume or
manner-of-sale limitations pursuant to Rule 144, and otherwise by physical
delivery to the address specified by the Holder in the Notice of Exercise within
3 Business Days from the delivery to the Company of the Notice of Exercise Form,
surrender of this Warrant (if required) and payment of the aggregate Exercise
Price as set forth above (the “Warrant Share Delivery
Date”).  This Warrant shall be deemed to have been exercised on
the date the Exercise Price is received by the Company.  The Warrant
Shares shall be deemed to have been issued, and Holder or any other person so
designated to be named therein shall be deemed to have become a holder of record
of such shares for all purposes, as of the date the Warrant has been exercised
by payment to the Company of the Exercise Price (or by cashless exercise, if
permitted) and all taxes required to be paid by the Holder, if any, pursuant to
Section 2(e)(v) prior to the issuance of such shares, have been
paid.


    
      
         


      

      
        4

        
          

        

      

      
         


      

    


    ii.     Delivery of New Warrants
Upon Exercise.  If this Warrant shall have been exercised in
part, the Company shall, at the request of a Holder and upon surrender of this
Warrant certificate, at the time of delivery of the certificate or certificates
representing Warrant Shares, deliver to Holder a new Warrant evidencing the
rights of Holder to purchase the unpurchased Warrant Shares called for by this
Warrant, which new Warrant shall in all other respects be identical with this
Warrant.

     

    iii.    Rescission
Rights.  If the Company fails to cause the transfer agent of
the Company to transmit to the Holder a certificate or the certificates
representing the Warrant Shares pursuant to Section 2(e)(i) by the Warrant Share
Delivery Date, then, the Holder will have the right to rescind such
exercise.

     

    iv.   No Fractional Shares or
Scrip.  No fractional shares or scrip representing fractional
shares shall be issued upon the exercise of this Warrant.  As to any
fraction of a share which Holder would otherwise be entitled to purchase upon
such exercise, the Company shall, at its election, either pay a cash adjustment
in respect of such final fraction in an amount equal to such fraction multiplied
by the Exercise Price or round up to the next whole share.

     

    v.    Charges, Taxes and
Expenses.  Issuance of certificates for Warrant Shares shall be
made without charge to the Holder for any issue or transfer tax or other
incidental expense in respect of the issuance of such certificate, all of which
taxes and expenses shall be paid by the Company, and such certificates shall be
issued in the name of the Holder or in such name or names as may be directed by
the Holder; provided, however, that in the
event certificates for Warrant Shares are to be issued in a name other than the
name of the Holder, this Warrant when surrendered for exercise shall be
accompanied by the Assignment Form attached hereto duly executed by the Holder
and the Company may require, as a condition thereto, the payment of a sum
sufficient to reimburse it for any transfer tax incidental thereto.

     

    vi.   Closing of
Books.  The Company will not close its stockholder books or
records in any manner which prevents the timely exercise of this Warrant,
pursuant to the terms hereof.

    f)          Call
Provision.  Subject to the provisions of Section 2(d) and this
Section 2(f), if, after the Effective Date, (i) the VWAP for each of 20
consecutive Business Days (the “Measurement Period,”
which 20 consecutive Business Day period shall not have commenced until after
the Effective Date) exceeds $5.00 (subject to adjustment for forward and reverse
stock splits, recapitalizations, stock dividends and the like after the Initial
Exercise Date), (ii) the average daily minimum volume for such Measurement
Period exceeds 75,000 shares of Common Stock per Business Day (subject to
adjustment for forward and reverse stock splits, recapitalizations, stock
dividends and the like after the Initial Exercise Date), (iii) the Holder is not
in possession of any information that constitutes, or might constitute, material
non-public information which was provided by the Company, and (iv) there is an
effective Registration Statement pursuant to which the Holder is permitted to
utilize the prospectus thereunder to resell all of the shares issuable pursuant
to the Transaction Documents (and the Company believes, in good faith, that such
effectiveness will continue uninterrupted for the foreseeable future) then, the
Company may, within 1 Business Day of the end of such Measurement Period, call
for cancellation of all or any portion of this Warrant for which a Notice of
Exercise has not yet been delivered (such right, a “Call”) for
consideration equal to $.001 per Share.  To exercise this right, the
Company must deliver to the Holder an irrevocable written notice (a “Call Notice”),
indicating therein the portion of unexercised portion of this Warrant to which
such notice applies.  If the conditions set forth below for such Call
are satisfied from the period from the date of the Call Notice through and
including the Call Date (as defined below), then any portion of this Warrant
subject to such Call Notice for which a Notice of Exercise shall not have been
received by the Call Date will be cancelled at 6:30 p.m. (New York City time) on
the 20th
Business Day after the date the Call Notice is received by the Holder (such date
and time, the “Call
Date”).  Any unexercised portion of this Warrant to which the
Call Notice does not pertain will be unaffected by such Call
Notice.  In furtherance thereof, the Company covenants and agrees that
it will honor all Notices of Exercise with respect to Warrant Shares subject to
a Call Notice that are tendered through 6:30 p.m. (New York City time) on the
Call Date.  The parties agree that any Notice of Exercise delivered
following a Call Notice which calls less than all the Warrants shall first
reduce to zero the number of Warrant Shares subject to such Call Notice prior to
reducing the remaining Warrant Shares available for purchase under this
Warrant.  For example, if (A) this Warrant then permits the Holder to
acquire 100 Warrant Shares, (B) a Call Notice pertains to 75 Warrant Shares, and
(C) prior to 6:30 p.m. (New York City time) on the Call Date the Holder tenders
a Notice of Exercise in respect of 50 Warrant Shares, then (x) on the Call Date
the right under this Warrant to acquire 25 Warrant Shares will be automatically
cancelled, (y) the Company, in the time and manner required under this Warrant,
will have issued and delivered to the Holder 50 Warrant Shares in respect of the
exercises following receipt of the Call Notice, and (z) the Holder may, until
the Termination Date, exercise this Warrant for 25 Warrant Shares (subject to
adjustment as herein provided and subject to subsequent Call
Notices).  Subject again to the provisions of this Section 2(f), the
Company may deliver subsequent Call Notices for any portion of this Warrant for
which the Holder shall not have delivered a Notice of
Exercise.  Notwithstanding anything to the contrary set forth in this
Warrant, the Company may not deliver a Call Notice or require the cancellation
of this Warrant (and any such Call Notice shall be void), unless, from the
beginning of the Measurement Period through the Call Date, (1) the Company shall
have honored in accordance with the terms of this Warrant all Notices of
Exercise delivered by  6:30 p.m. (New York City time) on the Call
Date, and (2) the Registration Statement shall be effective as to all Warrant
Shares and the prospectus thereunder available for use by the Holder for the
resale of all such Warrant Shares, and (3) the Common Stock shall be listed or
quoted for trading on the Trading Market, and (4) there is a sufficient number
of authorized shares of Common Stock for issuance of all Securities under the
Transaction Documents, and (5) the issuance of the shares shall not cause a
breach of any provision of 2(d) herein.  The Company’s right to call
the Warrants under this Section 2(f) shall be exercised ratably among the
Holders based on each Holder’s initial purchase of Warrants.

    Section
3.       Certain
Adjustments.

     

    a)        
Stock Dividends and
Splits. If the Company, at any time while this Warrant is outstanding:
(i) pays a stock dividend or otherwise make a distribution or distributions on
shares of its Common Stock or any other equity or equity equivalent securities
payable in shares of Common Stock (which, for avoidance of doubt, shall not
include any shares of Common Stock issued by the Company upon exercise of this
Warrant), (ii) subdivides outstanding shares of Common Stock into a larger
number of shares, (iii) combines (including by way of reverse stock split)
outstanding shares of Common Stock into a smaller number of shares or (iv)
issues by reclassification of shares of the Common Stock any shares of capital
stock of the Company, then in each case the Exercise Price shall be multiplied
by a fraction of which the numerator shall be the number of shares of Common
Stock (excluding treasury shares, if any) outstanding immediately before such
event and of which the denominator shall be the number of shares of Common Stock
outstanding immediately after such event and the number of shares issuable upon
exercise of this Warrant shall be proportionately adjusted such that the
aggregate Exercise Price of this Warrant shall remain unchanged.  Any
adjustment made pursuant to this Section 3(a) shall become effective immediately
after the record date for the determination of stockholders entitled to receive
such dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision, combination or
re-classification.


    
      
         


      

      
        7

        
          

        

      

      
         


      

    

     

    b)         Fundamental
Transaction. If, at any time while this Warrant is outstanding, (i) the
Company effects any merger or consolidation of the Company with or into another
Person, (ii) the Company effects any sale of all or substantially all of its
assets in one or a series of related transactions, (iii) any tender offer or
exchange offer (whether by the Company or another Person) is completed pursuant
to which holders of Common Stock are permitted to tender or exchange their
shares for other securities, cash or property or (iv) the Company effects any
reclassification of the Common Stock or any compulsory share exchange pursuant
to which the Common Stock is effectively converted into or exchanged for other
securities, cash or property (each “Fundamental
Transaction”), then, upon any subsequent exercise of this Warrant, the
Holder shall have the right to receive, for each Warrant Share that would have
been issuable upon such exercise immediately prior to the occurrence of such
Fundamental Transaction, the number of shares of Common Stock of the successor
or acquiring corporation or of the Company, if it is the surviving corporation,
and any additional consideration (the “Alternate
Consideration”) receivable as a result of such merger, consolidation or
disposition of assets by a holder of the number of shares of Common Stock for
which this Warrant is exercisable immediately prior to such event. For purposes
of any such exercise, the determination of the Exercise Price shall be
appropriately adjusted to apply to such Alternate Consideration based on the
amount of Alternate Consideration issuable in respect of one share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the
Exercise Price among the Alternate Consideration in a reasonable manner
reflecting the relative value of any different components of the Alternate
Consideration.  If holders of Common Stock are given any choice as to
the securities, cash or property to be received in a Fundamental Transaction,
then the Holder shall be given the same choice as to the Alternate Consideration
it receives upon any exercise of this Warrant following such Fundamental
Transaction.  To the extent necessary to effectuate the foregoing
provisions, any successor to the Company or surviving entity in such Fundamental
Transaction shall issue to the Holder a new warrant consistent with the
foregoing provisions and evidencing the Holder’s right to exercise such warrant
into Alternate Consideration. The terms of any agreement pursuant to which a
Fundamental Transaction is effected shall include terms requiring any such
successor or surviving entity to comply with the provisions of this Section 3(b)
and insuring that this Warrant (or any such replacement security) will be
similarly adjusted upon any subsequent transaction analogous to a Fundamental
Transaction. Notwithstanding anything to the contrary, in the event of a
Fundamental Transaction that is (1) an all cash transaction, (2) a “Rule 13e-3
transaction” as defined in Rule 13e-3 under the Exchange Act, or (3) a
Fundamental Transaction involving a person or entity not traded on a national
securities exchange, the Nasdaq Global Select Market, the Nasdaq Global Market,
or the Nasdaq Capital Market, the Company or any successor entity shall pay at
the Holder’s option, exercisable at any time concurrently with or within 30 days
after the consummation of the Fundamental Transaction, an amount of cash equal
to the value of this Warrant as determined in accordance with the Black Scholes
Option Pricing Model obtained from the “OV” function on Bloomberg L.P. using (A)
a price per share of Common Stock equal to the VWAP of the Common Stock for the
Business Day immediately preceding the date of consummation of the
applicable  Fundamental Transaction, (B) a risk-free interest rate
corresponding to the U.S. Treasury rate for a 30 day period immediately prior to
the consummation of the applicable Fundamental Transaction, (C) an expected
volatility equal to the 100 day volatility obtained from the “HVT” function on
Bloomberg L.P. determined as of the Business Day immediately following the
public announcement of the applicable Fundamental Transaction and (D) a
remaining option time equal to the time between the date of the public
announcement of such transaction and the Termination Date.

     

    c)         Calculations. All
calculations under this Section 3 shall be made to the nearest cent or the
nearest 1/100th of a share, as the case may be. For purposes of this Section 3,
the number of shares of Common Stock deemed to be issued and outstanding as of a
given date shall be the sum of the number of shares of Common Stock (excluding
treasury shares, if any) issued and outstanding.

     

    d)         Notice to
Holder.

     

    i.      Adjustment to Exercise
Price. Whenever the Exercise Price is adjusted pursuant to any provision
of this Section 3, the Company shall promptly mail to the Holder a notice
setting forth the Exercise Price after such adjustment and setting forth a brief
statement of the facts requiring such adjustment.

    ii.     Notice to Allow Exercise by
Holder. If (A) the Company shall declare a dividend (or any other
distribution in whatever form) on the Common Stock, (B) the Company shall
declare a special nonrecurring cash dividend on or a redemption of the Common
Stock, (C) the Company shall authorize the granting to all holders of the Common
Stock rights or warrants to subscribe for or purchase any shares of capital
stock of any class or of any rights, (D) the approval of any stockholders of the
Company shall be required in connection with any reclassification of the Common
Stock, any consolidation or merger to which the Company is a party, any sale or
transfer of all or substantially all of the assets of the Company, of any
compulsory share exchange whereby the Common Stock is converted into other
securities, cash or property, or (E) the Company shall authorize the voluntary
or involuntary dissolution, liquidation or winding up of the affairs of the
Company, then, in each case, the Company shall cause to be mailed to the Holder
at its last address as it shall appear upon the Warrant Register of the Company,
at least 20 calendar days prior to the applicable record or effective date
hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend, distribution, redemption, rights or
warrants, or if a record is not to be taken, the date as of which the holders of
the Common Stock of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which
such reclassification, consolidation, merger, sale, transfer or share exchange
is expected to become effective or close, and the date as of which it is
expected that holders of the Common Stock of record shall be entitled to
exchange their shares of the Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer or
share exchange; provided that the failure to mail such notice or any defect
therein or in the mailing thereof shall not affect the validity of the corporate
action required to be specified in such notice.  The Holder is
entitled to exercise this Warrant during the period commencing on the date of
such notice to the effective date of the event triggering such
notice.

     

    Section
4.       Transfer of
Warrant.

     

    a)         Transferability.  Subject
to compliance with any applicable securities laws and the conditions set forth
in Section 4(d) hereof and to the provisions of Section 4.1 of the Purchase
Agreement, this Warrant and all rights hereunder (including, without limitation,
any registration rights) are transferable, in whole or in part, upon surrender
of this Warrant at the principal office of the Company or its designated agent,
together with a written assignment of this Warrant substantially in the form
attached hereto duly executed by the Holder or its agent or attorney and funds
sufficient to pay any transfer taxes payable upon the making of such
transfer.  Upon such surrender and, if required, such payment, the
Company shall execute and deliver a new Warrant or Warrants in the name of the
assignee or assignees, as applicable, and in the denomination or denominations
specified in such instrument of assignment, and shall issue to the assignor a
new Warrant evidencing the portion of this Warrant not so assigned, and this
Warrant shall promptly be cancelled.  The Warrant, if properly
assigned, may be exercised by a new holder for the purchase of Warrant Shares
without having a new Warrant issued.

    b)         New Warrants. This
Warrant may be divided or combined with other Warrants upon presentation hereof
at the aforesaid office of the Company, together with a written notice
specifying the names and denominations in which new Warrants are to be issued,
signed by the Holder or its agent or attorney.  Subject to compliance
with Section 4(a), as to any transfer which may be involved in such division or
combination, the Company shall execute and deliver a new Warrant or Warrants in
exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice. 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 Warrant Shares issuable pursuant thereto.

     

    c)         Warrant Register. The
Company shall register this Warrant, upon records to be maintained by the
Company for that purpose (the “Warrant Register”),
in the name of the record Holder hereof from time to time.  The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the
Holder, and for all other purposes, absent actual notice to the
contrary.

     

    d)         Transfer
Restrictions. If, at the time of the surrender of this Warrant in connection with
any transfer of this Warrant, the transfer of this Warrant shall not be
either (i) registered pursuant to an effective
registration statement under the Securities
Act and under applicable state securities
or blue sky laws or (ii) eligible for
resale without volume or manner-of-sale restrictions pursuant to Rule
144, the Company may require, as a
condition of allowing such transfer, that
the Holder or transferee of this Warrant,
as the case may be, comply with the
provisions of Section 4.1 of the Purchase Agreement.

     

    Section
5.       Miscellaneous.

     

    a)         No Rights as Stockholder
Until Exercise.  This Warrant does not entitle the Holder to
any voting rights or other rights as a stockholder of the Company prior to the
exercise hereof as set forth in Section 2(e)(i).

     

    b)         Loss, Theft, Destruction or
Mutilation of Warrant. The Company covenants that upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant or any stock certificate relating to
the Warrant Shares, and in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it (which, in the case of the Warrant, shall
not include the posting of any bond), and upon surrender and cancellation of
such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

     

    c)         Saturdays, Sundays,
Holidays, etc.  If the last or appointed day for the taking of
any action or the expiration of any right required or granted herein shall not
be a Business Day, then, such action may be taken or such right may be exercised
on the next succeeding Business Day.

    d)         Authorized
Shares.

     

    The
Company covenants that, during the period the Warrant is outstanding, it will
reserve from its authorized and unissued Common Stock a sufficient number of
shares to provide for the issuance of the Warrant Shares upon the exercise of
any purchase rights under this Warrant.  The Company further covenants
that its issuance of this Warrant shall constitute full authority to its
officers who are charged with the duty of executing stock certificates to
execute and issue the necessary certificates for the Warrant Shares upon the
exercise of the purchase rights under this Warrant.  The Company will
take all such reasonable action as may be necessary to assure that such Warrant
Shares may be issued as provided herein without violation of any applicable law
or regulation, or of any requirements of the Trading Market upon which the
Common Stock may be listed.  The Company covenants that all Warrant
Shares which may be issued upon the exercise of the purchase rights represented
by this Warrant will, upon exercise of the purchase rights represented by this
Warrant, be duly authorized, validly issued, fully paid and nonassessable and
free from all taxes, liens and charges created by the Company in respect of the
issue thereof (other than taxes in respect of any transfer occurring
contemporaneously with such issue).

     

    Except
and to the extent as waived or consented to by the Holder, the Company shall not
by any action, including, without limitation, amending its certificate of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, 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, 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 Holder as set forth in this Warrant against
impairment.  Without limiting the generality of the foregoing, the
Company will (i) not increase the par value of any Warrant Shares above the
amount payable therefor upon such exercise immediately prior to such increase in
par value, (ii) take all such action as may be necessary or appropriate in order
that the Company may validly and legally issue fully paid and nonassessable
Warrant Shares upon the exercise of this Warrant and (iii) use commercially
reasonable efforts to obtain all such authorizations, exemptions or consents
from any public regulatory body having jurisdiction thereof, as may be,
necessary to enable the Company to perform its obligations under this
Warrant.

     

    Before
taking any action which would result in an adjustment in the number of Warrant
Shares for which this Warrant is exercisable or in the Exercise Price, the
Company shall obtain all such authorizations or exemptions thereof, or consents
thereto, as may be necessary from any public regulatory body or bodies having
jurisdiction thereof.

    e)         Jurisdiction. All
questions concerning the construction, validity, enforcement and interpretation
of this Warrant shall be determined in accordance with the provisions of the
Purchase Agreement.

     

    f)          Restrictions.  The
Holder acknowledges that the Warrant Shares acquired upon the exercise of this
Warrant, if not registered, will have restrictions upon resale imposed by state
and federal securities laws.

     

    g)         Nonwaiver and
Expenses.  No course of dealing or any delay or failure to
exercise any right hereunder on the part of Holder shall operate as a waiver of
such right or otherwise prejudice Holder’s rights, powers or remedies,
notwithstanding the fact that all rights hereunder terminate on the Termination
Date.  If the Company willfully and knowingly fails to comply with any
provision of this Warrant, which results in any material damages to the Holder,
the Company shall pay to Holder such amounts as shall be sufficient to cover any
costs and expenses including, but not limited to, reasonable attorneys’ fees,
including those of appellate proceedings, incurred by Holder in collecting any
amounts due pursuant hereto or in otherwise enforcing any of its rights, powers
or remedies hereunder.

     

    h)         Notices.  Any
notice, request or other document required or permitted to be given or delivered
to the Holder by the Company shall be delivered in accordance with the notice
provisions of the Purchase Agreement.

     

    i)          Limitation of
Liability.  No provision hereof, in the absence of any
affirmative action by Holder to exercise this Warrant to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of Holder, shall
give rise to any liability of Holder for the purchase price of any Common Stock
or as a stockholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

     

    j)          Remedies.  The
Holder, in addition to being entitled to exercise all rights granted by law,
including recovery of damages, will be entitled to specific performance of its
rights under this Warrant.  The Company agrees that monetary damages
would not be adequate compensation for any loss incurred by reason of a breach
by it of the provisions of this Warrant and hereby agrees to waive and not to
assert the defense in any action for specific performance that a remedy at law
would be adequate.

     

    k)         Successors and
Assigns.  Subject to applicable securities laws, this Warrant
and the rights and obligations evidenced hereby shall inure to the benefit of
and be binding upon the successors of the Company and the successors and
permitted assigns of Holder.  The provisions of this Warrant are
intended to be for the benefit of all Holders from time to time of this Warrant
and shall be enforceable by the Holder or holder of Warrant Shares.

     

    l)          Amendment.  This
Warrant may be modified or amended or the provisions hereof waived with the
written consent of the Company and Holders holding Warrants at least equal to
55% of the Warrant Shares issuable upon exercise of all then outstanding
Warrants.

    m)        Severability.  Wherever
possible, each provision of this Warrant shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision of this
Warrant shall be prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provisions or the remaining provisions of
this Warrant.

     

    n)         Headings.  The
headings used in this Warrant are for the convenience of reference only and
shall not, for any purpose, be deemed a part of this Warrant.
