    THIS

2008, sets forth the terms under which MEDIS-EL LTD., a company
incorporated under the laws of the State of Israel (the “Holder”), has made certain

              1.  

            	
              General.
      The Holder shall, immediately upon execution of this Note, fund the
      Company an aggregate amount of $1,500,000 (One Million Five Hundred
      Thousand Dollars) (the “Funding Amount”) in
      order to provide, along with other cash resources that the Company
      currently has on hand, minimum sufficient funding for the Company for a
      one year period from the expected filing date of its Form
      20-F.

            


    

     

    
      	
              2.  

            	
              Interest.  The
      Funding Amount shall not bear any
interest.

            


    

     

    
      	
              3.  

            	
              Repayment.   Subject
      to Section 5, the remaining balance of the Note shall be repaid to the
      Holder upon the earliest to occur of (i) the sale of all or substantially
      all of the assets of the Company to a third party, (ii) the merger or
      other consolidation of the Company with a third party, or (iii) the
      provision of alternative funding to the Company (in which case, only an
      amount equal to such alternative funding shall be repaid). Notwithstanding
      the preceding repayment restrictions, the remaining balance of the note
      shall be repaid upon the demand of the Holder, provided that such demand
      may only be made after January 1, 2010.


            


    

     

    
      	
              4.  

            	
              Unsecured
      Obligation.  The Note shall be unsecured in all respects
      and shall be subordinated to all commercial indebtedness, whether secured
      or unsecured, of the Company, other than any currently outstanding
      indebtedness of the Company to the Holder under any capital note or other
      instrument similar to this Note that has been issued by the Company to the
      Holder prior to the date hereof.

            


    

     

    Events of
Default and Acceleration.  Notwithstanding anything to the
contrary in Section 3 above, and provided that the Holder is not in breach
of any of its undertakings hereunder, the Holder may, at its option, require
repayment of any part or all of the Note for the then outstanding Funding Amount
(unless the Company and the Holder shall have agreed in writing to an extension
or other accommodation), upon the institution of any proceeding against the
Company seeking to adjudicate it bankrupt or insolvent, or seeking liquidation,
winding up, reorganization, arrangement, adjustment, custodianship, protection
or relief of it or its debts under any law relating to bankruptcy, insolvency or
reorganization or relief of debtors, or seeking the entry of an order for relief
or the appointment of a receiver, custodian, trustee or other similar official
for it or for any substantial part of its property, which proceeding shall not
have been terminated within 45 days.

     

    
      	
              5.  

            	
              Conversion
      into Equity.  This Note shall be convertible in whole or
      in part at any time, upon the request of the Holder, into additional
      premium on account of the price-per-share paid by the Holder with respect
      to the Company’s shares currently held by the
  Holder.

            


    

     

    
      	
              6.  

            	
              Waiver.  No
      act or omission by any of the parties hereof, including specifically any
      failure to exercise any right, remedy or recourse, shall be deemed a
      waiver or release of the same, such waiver or release to be effective only
      as set forth in a written document executed by the parties hereof and then
      only to the extent specifically recited therein.  A waiver or
      release with reference to one event shall not be construed as continuing
      as a bar to or as a waiver or release of any subsequent right, remedy or
      recourse as to any subsequent
event.

            


    

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    
      	
              7.  

            	
              Waiver
      of Presentment. The Company hereby waives presentment for payment,
      notice of nonpayment, protest, notice of protest and all other notices,
      filing of suit and diligence in collecting the amounts due under the Note
      and agrees that the Holder shall not be required first to initiate any
      suit or exhaust its remedies against any other person or parties in order
      to enforce payment under this Note.

            


    

     

    
      	
              8.  

            	
              Governing
      Law.  The Note shall be governed by and construed in
      accordance with the laws of the State of Israel without regard to conflict
      of laws provisions.  The parties agree that the courts in the
      city of Tel Aviv, Israel shall have jurisdiction to hear and determine any
      suit, action or proceeding, and to settle any dispute, which may arise out
      of or in connection with this Note and, for such purposes, irrevocably
      submit to the non-exclusive jurisdiction of such
  courts.

            


    

     

    
      	
              9.  

            	
              Miscellaneous
      Provisions. This Note shall be binding on the successors and
      assigns of the Company and inure to the benefit of the Holder, its
      successors, endorsees and assigns.  If any terms or provisions
      of this Note are deemed invalid, the validity of all other terms and
      provisions hereof shall in no way be affected thereby. This Note may not
      be assigned or transferred in whole or in part by any party. Any notice
      under this Note shall be made in writing by personal delivery, certified
