 [REVERSE OF WARRANT CERTIFICATE] 
  
 1. Warrant Agreement. 
  
 The Series A Warrants evidenced by this Series A Warrant Certificate are part of a duly authorized issue of Series A Warrants issued or to be issued
pursuant to a Warrant Agreement dated as of                     , 2005 (the “Warrant Agreement”), between the Company and Mellon
Investor Services L.L.C., as warrant agent (the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of
rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the registered holders or registered holder) of the Series A Warrants. To the extent
permitted by law, in the event of an inconsistency or conflict between the terms of this Series A Warrant Certificate and the Warrant Agreement, the terms of the Warrant Agreement will prevail. Capitalized terms used in this Series A Warrant
Certificate that are defined in the Warrant Agreement shall have the meanings provided in the Warrant Agreement for purposes of this Series A Warrant Certificate, unless otherwise defined in this Series A Warrant Certificate. 
  
 2. Exercise. 
  
 Series A Warrants may be exercised at any time on or after 9:00 a.m. on the
Issue Date and on or before 5:00 p.m. New York City time on the Series A Expiration Date. In order to exercise all or any of the Series A Warrants represented by this Series A Warrant Certificate, the holder must deliver to the Warrant Agent, at its
Corporate Trust Office set forth in the Warrant Agreement, this Series A Warrant Certificate and the form of election to purchase below duly completed, which signature shall be medallion guaranteed by an institution which is a member of a Securities
Transfer Association recognized signature guarantee program, and upon payment to the Warrant Agent for the account of the Company of the Series A Exercise Price in the manner set forth in the Warrant Agreement for the number of Warrant Shares in
respect of which such Warrants are then exercised. 
  
 No Series A
Warrant may be exercised after 5:00 p.m., New York City time on the Series A Expiration Date, and to the extent not exercised by such time the Series A Warrants shall become void. 
  
 Notwithstanding anything to the contrary set forth in this Series A Warrant Certificate or in the Warrant Agreement, no
holder may exercise a Warrant if the issuance of Warrant Shares to the holder of such Warrant upon the exercise thereof would cause the percentage of shares of Common Stock then outstanding that is owned by Aliens to exceed the Permitted Percentage.

  
 3. Adjustments. 
  
 The Warrant Agreement provides that, upon the occurrence of certain events,
the Series A Exercise Price set forth on the face hereof may, subject to certain conditions, be adjusted. The Warrant Agreement also provides that the number of shares of Common Stock issuable upon the exercise of each Series A Warrant shall be
adjusted in certain events. 






 4. No Fractional Shares. 
  
 No fractions of a share of Common Stock will be issued upon the exercise of any Series A Warrant, but the Company will pay
the cash value thereof determined as provided in the Warrant Agreement. 
  
 5. Registered Form; Transfer and Exchange. 
  
 The Series A Warrants are in registered form. Warrant Certificates, when surrendered at the office of the Warrant Agent by the registered holder thereof in person or by legal representative or attorney duly authorized in writing, may be
exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge (except as specified in the Warrant Agreement), for another Warrant Certificate or Warrant Certificates of like
tenor evidencing in the aggregate a like number of Series A Warrants. 
  
 Upon due presentation for registration of transfer of this Series A Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of
Series A Warrants shall be issued to the transferee(s) in exchange for this Series A Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in
connection therewith. 
  
 The Company and the Warrant Agent may
deem and treat the registered holder(s) hereof as the absolute owner(s) of this Series A Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any
distribution to the holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Series A Warrants nor this Series A Warrant Certificate entitles any holder
hereof to any rights of a stockholder of the Company. 
  
 6.
Countersignature. 
  
 This Warrant Certificate shall not be
valid unless countersigned by the Warrant Agent. 
  
 7.
Governing Law. 
  
 This Warrant Certificate shall be governed
by and construed in accordance with the internal laws of the State of New York. 
  
 8. Abbreviations. 
  
 Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common),
