 THIS CERTIFIES THAT 
  
 or registered assigns, is the registered holder of the number of Class B Warrants
(“Class B Warrants”) set forth above. As provided in the Warrant Agreement (the “Warrant Agreement”), and as more fully described herein, each Class B Warrant entitles the holder thereof to purchase from DayStar Technologies,
Inc., a corporation incorporated under the laws of the State of Delaware (the “Company”), subject to the terms and conditions set forth hereinafter and in the Warrant Agreement, at any time on or after
                    , 2004 and before the close of business on
                , 2009 (“Expiration Date”), one fully paid and non-assessable share of Common Stock, par value $0.01 per share, of the Company
(“Common Stock”) upon presentation and surrender of this Warrant Certificate, with the instructions for the registration and delivery of Common Stock filled in, at the stock transfer office in Glendale, California, of U.S.
Stock Transfer Corporation, Warrant Agent of the Company (“Warrant Agent”) or of its successor warrant agent or, if there be no successor warrant agent, at the corporate offices of the Company, and upon payment of the Exercise Price (as
defined in the Warrant Agreement) and any applicable taxes paid either in cash, or by certified or official bank check, payable in lawful money of the United States of America to the order of the Company. Each Class B Warrant initially entitles the
holder to purchase one share of Common Stock for $        . The number and kind of securities or other property for which the Class B Warrants are exercisable are subject to adjustment in certain
events, such as mergers, splits, stock dividends, reverse splits and the like, to prevent dilution. All Class B Warrants not theretofore exercised will expire on the Expiration Date. 
  
 This Warrant Certificate is subject to all of the terms, provisions and conditions of the Warrant Agreement, dated as of
                , 2004, between the Company and the Warrant Agent, to all of which terms, provisions and conditions the registered holder of this Warrant
Certificate consents by acceptance hereof. The Warrant Agreement is incorporated herein by reference and made a part hereof and reference is made to the Warrant Agreement for a 







 full description of the rights, limitations of rights, obligations, duties and immunities of the Warrant Agent, the
Company and the holders of the Warrant Certificates. Copies of the Warrant Agreement are available for inspection at the stock transfer office of the Warrant Agent or may be obtained upon written request addressed to the Company at DayStar
Technologies, Inc., 900 Golden Gate Terrace, Suite A, Grass Valley, California 95945, Attention: Chief Financial Officer. 
  
 The Company shall not be required upon the exercise of the Class B Warrants evidenced by this Warrant Certificate to issue fractions of Class B Warrants, Common Stock or
other securities, but shall make adjustment therefor in cash on the basis of the current market value of any fractional interest as provided in the Warrant Agreement. 
  
 In certain cases, the sale of securities by the Company upon exercise of Class B Warrants may violate the securities laws of the United
States, certain states thereof or other jurisdictions. The Company has agreed to use all commercially reasonable efforts to cause a registration statement to continue to be effective during the term of the Class B Warrants with respect to such sales
under the Securities Act of 1933, and to take such action under the laws of various states as may be required to cause the sale of securities upon exercise to be lawful. However, the Company will not be required to honor the exercise of Class B
Warrants if, in the opinion of the Board of Directors, upon advice of counsel, the sale of securities upon such exercise would be unlawful. In certain cases, the Company may, but is not required to, purchase Class B Warrants submitted for exercise
for a cash price equal to the difference between the market price of the securities obtainable upon such exercise and the exercise price of such Class B Warrants. 
  
 This Warrant Certificate, with or without other Certificates, upon surrender to the Warrant Agent, any successor warrant agent or, in the
absence of any successor warrant agent, at the corporate offices of the Company, may be exchanged for another Warrant Certificate or Certificates evidencing in the aggregate the same number of Class B Warrants as the Warrant Certificate or
Certificates so surrendered. If the Class B Warrants evidenced by this Warrant Certificate shall be exercised in part, the holder hereof shall be entitled to receive upon surrender hereof another Warrant Certificate or Certificates evidencing the
number of Class B Warrants not so exercised. 
  
 No holder of this Warrant
Certificate, as such, shall be entitled to vote, receive dividends or be deemed the holder of Common Stock or any other securities of the Company which may at any time be issuable on the exercise hereof for any purpose whatsoever, nor shall anything
contained in the Warrant Agreement or herein be construed to confer upon the holder of this Warrant Certificate, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter
submitted to stockholders at any meeting thereof or give or withhold consent to any corporate action (whether upon any matter submitted to stockholders at any meeting thereof, or give or withhold consent to any merger, recapitalization, issuance of
stock, reclassification of stock, change of par value or change of stock to no par value, consolidation, conveyance or otherwise) or to receive notice of meetings or other actions affecting stockholders (except as provided in the Warrant Agreement)
or to receive dividends or subscription rights or otherwise until the Class B Warrants evidenced by this Warrant Certificate shall have been exercised and the Common Stock purchasable upon the exercise thereof shall have become deliverable as
provided in the Warrant Agreement. 







 If this Warrant Certificate shall be surrendered for exercise within any period during which the transfer books for the
Company’s Common Stock or other class of stock purchasable upon the exercise of the Class B Warrants evidenced by this Warrant Certificate are closed for any purpose, the Company shall not be required to make delivery of certificates for shares
purchasable upon such transfer until the date of the reopening of said transfer books. 
  
 Every holder of this Warrant Certificate by accepting the same consents and agrees with the Company, the Warrant Agent, and with every other holder of a Warrant Certificate that: 
  
 (a) this Warrant Certificate is transferable on the registry books of the Warrant Agent only upon the terms and conditions set forth in the
Warrant Agreement, and 
  
 (b) the Company and the Warrant Agent may deem and
treat the person in whose name this Warrant Certificate is registered as the absolute owner hereof (notwithstanding any notation of ownership or other writing thereon made by anyone other than the Company or the Warrant Agent) for all purposes
whatsoever and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. The Company shall not be required to issue or deliver any certificate for shares of Common Stock or other securities upon the exercise of Class
B Warrants evidenced by this Warrant Certificate until any tax which may be payable in respect thereof by the holder of this Warrant Certificate pursuant to the Warrant Agreement shall have been paid, such tax being payable by the holder of this
Warrant Certificate at the time of surrender. 
  
 This Warrant Certificate shall
not be valid or obligatory for any purpose until it shall have been countersigned by the Warrant Agent. 
  
 WITNESS the facsimile signatures of the proper officers of the Company and its corporate seal.
