    Altair
Nanotechnologies Inc., a corporation continued under the Canada Business
Corporations Act (the "Company"), hereby certifies
that, for good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, ______________, 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 surrender 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), ______________ (_____________)1 fully paid
nonassessable shares of Common Stock (as defined below) (the "Warrant
Shares").  Except as otherwise defined herein, capitalized

issued pursuant to (i) Section 2 of that
certain Subscription Agreement (the “Subscription Agreement”),
dated as of May 28, 2009 (the "Subscription Date"), by and
between the Company and the Holder, and (ii) the Company’s Registration
Statement on Form S-3 (File number 333-137099) (the “Registration
Statement”).  This Warrant is one of a series of Warrants in
substantially the same form (the “Warrants”) exercisable for an
aggregate of 6,596,958 Warrant Shares (the “Aggregate Warrant
Shares”).

     _______________ 
      1 Insert a
number of shares equal to 55% of the number of Common Shares purchased under the
Subscription Agreement.

       

    


    
      
         


      

      
         


        
          

        

      

      
         


      

    


    1.            
EXERCISE OF
WARRANT.

     

    (a)           Mechanics of
Exercise.  Subject to the terms and conditions hereof, this
Warrant may be exercised by the Holder on any Business Day on or after the
Issuance Date and on or before the Expiration Date, in whole or in part, by (i)
delivery of a written notice, in the form attached hereto as Exhibit A (the "Exercise Notice"), of the
Holder's election to exercise this Warrant and (ii) (A) payment to the
Company of an amount equal to the applicable Exercise Price multiplied by the
number of Warrant Shares as to which this Warrant is being exercised (the "Aggregate Exercise Price") in
cash or by wire transfer of immediately available funds or (B) provided the
conditions for cashless exercise set forth in Section 1(d) are satisfied, by
notifying the Company that this Warrant is being exercised pursuant to a
Cashless Exercise (as defined in Section
1(d)).  The Holder shall not be required to deliver the
original Warrant in order to effect an exercise hereunder, but shall deliver the
original Warrant within five Business Days thereafter.  Execution and
delivery of the Exercise Notice with respect to less than all of the Warrant
Shares shall have the same effect as cancellation of the original Warrant and
issuance of a new Warrant evidencing the right to purchase the remaining number
of Warrant Shares.  On or before the first (1st)
Business Day following the date on which the Company has received each of the
Exercise Notice and the Aggregate Exercise Price (or notice of a Cashless
Exercise) (the "Exercise
Delivery Documents"), the Company shall transmit by facsimile an
acknowledgment of confirmation of receipt of the Exercise Delivery Documents to
the Holder and the Company's transfer agent (the "Transfer
Agent").  On or before the third (3rd)
Business Day following the date on which the Company has received all of the
Exercise Delivery Documents (the "Share Delivery Date"), 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 Warrant Shares 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 Agent Commission system, or (Y) if the Transfer Agent is
not participating in the DTC Fast Automated Securities Transfer Program, issue
and dispatch by overnight courier to the address as specified in the Exercise
Notice, a certificate, registered in the Company's share register in the name of
the Holder or its designee, for the number of shares of Common Stock to which
the Holder is entitled pursuant to such exercise.  Upon delivery of
the Exercise Delivery Documents, 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 the Company shall as soon as practicable and in
no event later than three Business Days after any exercise and at its own
expense, issue 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 down to the nearest whole number; provided, however, that if any
fractional share of Common Stock would otherwise be deliverable upon such
exercise, the Company, in lieu of delivering such fractional share, shall pay to
the Holder an amount in cash equal to the Market Price of such fractional share
of Common Stock on the date of exercise. The Company shall pay any and all
Transfer Agent fees and documentary stamp taxes attributable to the initial
issuance of Warrant Shares issuable upon the exercise of this Warrant. The
Holder shall be responsible for any income taxes due under federal, state or
other law, if any such tax is due.

    (b)           Exercise
Price.  For purposes of this Warrant, "Exercise Price" means $1.00,
subject to adjustment as provided herein.

     

    (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 three (3) Business Days of
receipt of the Exercise Delivery Documents in compliance with the terms of this
Section 1, 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, and if on or after such 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 (a "Buy-In"),
then 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 (and to issue such
Warrant Shares) shall terminate, or (ii) promptly honor its obligation to
deliver to the Holder a certificate or certificates representing such Warrant
Shares 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 Bid Price on the date of exercise.

     

    (d)           Cashless Exercise.
 Notwithstanding
anything contained herein to the contrary, if a registration statement covering
the Warrant Shares that are the subject of the Exercise Notice, or an exemption
from registration, is not
available for the issuance or resale of such Warrant Shares (the "Unavailable Warrant Shares"),
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

    For purposes of the foregoing
formula:

     

    
      	
               
      

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

            
	 	
              B=
      the arithmetic average of the Closing Sale Prices of the shares of Common
      Stock for the five (5) consecutive Trading Days ending on the date
      immediately preceding the date of the Exercise Notice.

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

    (e)           Rule
144.  For purposes of Rule 144(d) promulgated under the
Securities Act, as in effect on the date hereof, assuming the Holder is not an
affiliate of the Company, it is intended that the Warrant Shares issued in a
Cashless Exercise shall be deemed to have been acquired by the Holder, and the
holding period for the Warrant Shares shall be deemed to have commenced, on the
date this Warrant was originally issued pursuant to the Subscription
Agreement.

     

    (f)           
Disputes.  In
the case of a dispute as to the determination of the Exercise Price or the
arithmetic calculation of the Warrant Shares, the Company shall promptly issue
to the Holder the number of Warrant Shares that are not disputed.

     

    (g)           Beneficial
Ownership.  The Holder shall not have the right to exercise
this Warrant, to the extent that after giving effect to such exercise, the
Holder (together with the Holder’s affiliates) would beneficially own in excess
of 4.99% (the "Maximum
Percentage") of the shares of Common Stock outstanding immediately after
giving effect to such exercise. The Company shall be entitled to rely on receipt
of an Exercise Notice as an indication that Holder will not, pursuant to such
exercise, exceed the Maximum Percentage. For purposes of the foregoing sentence,
the aggregate number of shares of Common Stock beneficially owned by such Holder
and its affiliates shall include the number of shares of Common Stock issuable
upon exercise of this Warrant with respect to which the determination of such
sentence is being made, but shall exclude shares of Common Stock which would be
issuable upon (i) exercise of the remaining, unexercised portion of this Warrant
beneficially owned by such Holder and its affiliates and (ii) exercise or
conversion of the unexercised or unconverted portion of any other securities of
the Company beneficially owned by such Holder and its affiliates (including,
without limitation, any convertible notes or convertible preferred stock or
warrants) subject to a limitation on conversion or exercise analogous to the
limitation contained herein.  Except as set forth in the preceding
sentence, for purposes of this paragraph, beneficial ownership shall be
calculated in accordance with Section 13(d) of the Securities Exchange Act of
1934, as amended (the “Exchange
Act”), 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.  For purposes of this
Warrant, in determining the number of outstanding shares of Common Stock, the
Holder may rely on the number of outstanding shares of Common Stock as reflected
in the most recent of (1) the Company's most recent Form 10-K, Form 10-Q,
Current Report on Form 8-K or other public filing with the Securities and
Exchange Commission, as the case may be, (2) a public announcement by the
Company or (3) any other notice by the Company or the Transfer Agent setting
forth the number of shares of Common Stock outstanding.  For any
reason at any time, upon the written or oral request of the Holder, the Company
shall within two (2) 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 and its affiliates since the date as of
which such number of outstanding shares of Common Stock was
reported.  By written notice to the Company, the Holder may from time
to time increase or decrease the Maximum Percentage to any other percentage not
in excess of 9.99% specified in such notice; provided that (i) any such
increase will not be effective until the sixty-first (61st) day
after such notice is delivered to the Company, and (ii) any such increase or
decrease will apply only to the Holder.  The provisions of this
paragraph shall be construed and implemented in a manner otherwise than in
strict conformity with the terms of this Section 1(h) 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.

    2.            
ADJUSTMENT OF EXERCISE
PRICE AND NUMBER OF WARRANT SHARES.  The Exercise Price and the
number of Warrant Shares shall be adjusted from time to time as
follows:

     

    (a)           Adjustment upon Issuance of
Shares of Common Stock.  If and whenever on or after the
Subscription Date, 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 shares of Common Stock deemed to have been issued by the
Company in connection with any Excluded Issuance for a consideration per share
(the "New Issuance
Price") less than a price (the "Applicable Price") equal to
the Exercise Price in effect immediately prior to such issue or sale or deemed
issuance or sale (the foregoing a "Dilutive Issuance"), then
immediately after such Dilutive Issuance, the Exercise Price then in effect
shall be reduced to the product of (A) the Exercise Price in effect immediately
prior to such Dilutive Issuance and (B) the quotient determined by dividing (1)
the sum of (I) the product derived by multiplying the Exercise Price in effect
immediately prior to such Dilutive Issuance and the number of shares of Common
Stock Deemed Outstanding immediately prior to such Dilutive Issuance plus (II)
the consideration, if any, received by the Company upon such Dilutive Issuance,
by (2) the product derived by multiplying (I) the Exercise Price in effect
immediately prior to such Dilutive Issuance by (II) the number of shares of
Common Stock Deemed Outstanding immediately after such Dilutive Issuance. For
purposes of determining the adjusted Exercise Price under this Section 2(a), the
following shall be applicable:

     

    (i)           
Issuance of
Options.  If the Company in any manner grants 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(a)(i), the "lowest price per share for which one
share of Common Stock is issuable upon exercise of such Options or upon
conversion, exercise or exchange of such Convertible Securities issuable upon
exercise of any such Option" shall be equal to 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 the Option, upon exercise
of the Option and upon conversion, exercise or exchange of any Convertible
Security issuable upon exercise of such Option.  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. 

     


    
      
         


      

      
        5

        
          

        

      

      
         


      

    


    (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(a)(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 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.  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(a), no further adjustment of the Exercise
Price shall be made by reason of such issue or sale.

     

    (iii)           Change in Option Price or
Rate of Conversion.  If the purchase 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, then
the Exercise Price and the number of Warrant Shares in effect at the time of
such increase or decrease shall be adjusted to the Exercise Price and the number
of Warrant Shares 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(a)(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(a) shall be made if such adjustment would result in an increase of the
Exercise Price then in effect or a decrease in the number of Warrant
Shares.

    (iv)           Calculation of Consideration
Received.  In case any Option is issued in connection with the
issue or sale of other securities of the Company, together comprising one
integrated transaction, (x) the Options will be deemed to have been issued for a
value determined by use of the Black Scholes Option Pricing Model (the "Option Value") and (y) the
other securities issued or sold in such integrated transaction shall be deemed
to have been issued for the difference of (I) the aggregate consideration
received by the Company, less (II) the Option Value.  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 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 securities, in which case the amount of consideration
received by the Company will be the Weighted Average Price of such security on
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 securities will be determined in good faith by the Board of Directors of
the Company.  In the event that the holders of Warrants exercisable
for a majority of the Aggregate Warrant Shares (the “Majority Holders”) object in
writing to a valuation within ten (10) days after the occurrence of an event
requiring valuation (the "Valuation Event"), then the
fair value of such consideration will be determined within five (5) Business
Days after the tenth (10th) day
following the Valuation Event by an independent, reputable appraiser jointly
selected by the Company and the Majority Holders.  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 equally by the
Company and the Holders.

     

    (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.

     


    
      
         


      

      
        7

        
          

        

      

      
         


      

    


    (vi)           Voluntary Adjustment By
Company.  The Company may at any time during the term of this
Warrant reduce the then current Exercise Price to any amount and for any period
of time deemed appropriate by the Board of Directors of the
Company.

     

    (b)           Adjustment upon Subdivision
or Combination of Common Stock.  If the Company at any time on
or after the Subscription Date subdivides (by any stock split, stock dividend,
recapitalization, reorganization, scheme, arrangement or otherwise) one or more
classes of its outstanding shares of Common Stock into a greater number of
shares, the Exercise Price in effect immediately prior to such subdivision will
be proportionately reduced and the number of Warrant Shares will be
proportionately increased.  If the Company at any time on or after the
Subscription Date combines (by any stock split, stock dividend,
recapitalization, reorganization, scheme, arrangement or otherwise) one or more
classes of its outstanding shares of Common Stock into a smaller number of
shares, the Exercise Price in effect immediately prior to such combination will
be proportionately increased and the number of Warrant Shares will be
proportionately decreased.  Any adjustment under this Section 2(b)
shall become effective at the close of business on the date the subdivision or
combination becomes effective.

     

    (c)           Other
Events.  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 will make an appropriate adjustment in the Exercise Price and
the number of Warrant Shares so as to protect the rights of the Holder; provided
that no such adjustment pursuant to this Section 2(c) will
increase the Exercise Price or decrease the number of Warrant Shares as
otherwise determined pursuant to this Section 2.

     

    3.           
 RIGHTS UPON
DISTRIBUTION OF ASSETS.  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:

     

    (a)           any
Exercise Price in effect immediately prior to the close of business on the
record date fixed for the determination of holders of shares of Common Stock
entitled to receive the Distribution shall be reduced, effective as of the close
of business on such record date, to a price determined by multiplying such
Exercise Price by a fraction of which (i) the numerator shall be the Closing Bid
Price of the shares of Common Stock on the Trading Day immediately preceding
such record date minus the value of the Distribution (as determined in good
faith by the Company's Board of Directors) applicable to one share of Common
Stock, and (ii) the denominator shall be the Closing Bid Price of the shares of
Common Stock on the Trading Day immediately preceding such record date;
and

     

    (b)           the
number of Warrant Shares shall be increased to a number of shares equal to the
number of shares of Common Stock obtainable immediately prior to the close of
business on the record date fixed for the determination of holders of shares of
Common Stock entitled to receive the Distribution multiplied by the reciprocal
of the fraction set forth in the immediately preceding paragraph (a); provided that in the event
that the Distribution is of shares of Common Stock (or common stock) ("Other Shares of Common Stock")
of a company whose common shares are traded on a national securities exchange or
a national automated quotation system, then the Holder may elect to receive a
warrant to purchase Other Shares of Common Stock in lieu of an adjustment in the
number of Warrant Shares, the terms of which shall be identical to those of this
Warrant, except that such warrant shall be exercisable into the number of shares
of Other Shares of Common Stock that would have been payable to the Holder
pursuant to the Distribution had the Holder exercised this Warrant immediately
prior to such record date and with an aggregate exercise price equal to the
product of the amount by which the exercise price of this Warrant was decreased
with respect to the Distribution pursuant to the terms of the immediately
preceding paragraph (a) and the number of Warrant Shares calculated in
accordance with the first part of this paragraph (b).

    4.           
 PURCHASE RIGHTS;
FUNDAMENTAL TRANSACTIONS.

     

    (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 the exercise of this Warrant) 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.

     

    (b)           Fundamental
Transactions.  The Company shall not enter into or be party to
a Fundamental Transaction unless the Successor Entity assumes this Warrant in
accordance with the provisions of this Section (4)(b), including agreements to
deliver to each holder of Warrants in exchange for such Warrants a security of
the Successor Entity evidenced by a written instrument substantially similar in
form and substance to this Warrant, including, without limitation, an adjusted
exercise price equal to the value for the shares of Common Stock reflected by
the terms of such Fundamental Transaction, and 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.  Upon the occurrence of any Fundamental Transaction, the
Successor Entity shall succeed to, and be substituted for (so that from and
after the date of such Fundamental Transaction, the provisions of this Warrant
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 with the same effect as if such
Successor Entity had been named as the Company herein.   In
addition to and not in substitution for any other rights hereunder, prior to the
consummation of any 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 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) purchasable 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 such Fundamental Transaction had the Warrant been exercised immediately prior
to such Fundamental Transaction.  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 consideration it receives upon any exercise of this Warrant following such
Fundamental Transaction.   The provisions of this Section shall
apply similarly and equally to successive Fundamental Transactions and Corporate
Events and shall be applied without regard to any limitations on the exercise of
this Warrant.  Notwithstanding the foregoing, in the event of a
Fundamental Transaction, at the request of the Holder delivered before the 15th
day after consummation of such Fundamental Transaction, the Company (or the
Successor Entity) shall purchase this Warrant from the Holder by paying to the
Holder, within five Business Days after such request (or, if later, within two
Business Days after the effective date of the Fundamental Transaction), cash in
an amount equal to the Black Scholes Value of the remaining unexercised portion
of this Warrant on the date of such Fundamental Transaction.

    5.            
NONCIRCUMVENTION.  The
Company hereby covenants and agrees that the Company will not, by amendment of
its Certificate of Incorporation, Bylaws 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.  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 this Warrant is 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 this Warrant,
100% of the number of shares of Common Stock issuable upon exercise of this
Warrant then outstanding (without regard to any limitations on
exercise).

     

    6.            
WARRANT HOLDER NOT

provided herein, the Holder, solely in such Person's 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 such
Person's 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 such Person 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.
