    FOR
      VALUE
      RECEIVED, SINGLE TOUCH INTERACTIVE, INC., a Nevada corporation (hereinafter
      called the “Borrower”), hereby promises to pay to the order of SINGLE TOUCH
      SYSTEMS INC., a Delaware corporation (hereinafter called the “Lender”), 32
      Poplar Place, Fanwood, New Jersey 07023, the principal sum of Four Hundred
      Twenty-Five Thousand Dollars ($425,000) (the “Loan”), in lawful money of the
      United States of America and in immediately available funds. 

    


    1. The
      outstanding principal balance of this Note, together with accrued and unpaid
      interest thereon, shall be due and payable on June 30, 2008 (the “Due Date”),
      which Due Date may be extended by the Borrower and the Lender in writing;
provided,
      however,
      that
      upon the consummation of a merger between the Borrower and the Lender, or an
      affiliate of the Lender (the “Merger”), all
      indebtedness evidenced hereby shall be deemed canceled and paid in
      full.

    


    2. This
      Note
      shall bear interest at the rate of twelve percent (12%) per annum on the unpaid
      principal balance hereof. Interest shall be calculated on the basis of a year
      of
      three hundred sixty (360) days applied to the actual days on which there exists
      an unpaid balance under this Note.

    


    3. Upon
      an
“Event of Default,” as defined in the Bridge Loan Agreement described below, the
      rate of interest accruing on the unpaid principal balance of this Note shall
      increase to eighteen percent (18%) per annum. Such default interest rate shall
      continue until all defaults are cured.

    


    4. This
      Note
      is subject to the terms of a Bridge Loan Agreement, as amended (the “Bridge Loan
      Agreement”) dated March 31, 2008 by and among the Borrower and the Lender. All
      capitalized and undefined terms herein shall have the meaning given them in
      the
      Bridge Loan Agreement. 

    


    5. Upon
      the
      occurrence of an Event of Default (including the passage of applicable cure
      periods) under the Bridge Loan Agreement, the entire principal amount
      outstanding hereunder and all accrued interest hereon, together with all other
      sums due hereunder, shall, as provided in the Bridge Loan Agreement, become
      immediately due and payable.

    


    
      
         

      

      
         

        
          

        

      

      
         

      

    

    Notwithstanding
      the foregoing, if an Event of Default is waived by the Lender, the Borrower
      shall use its reasonable best efforts to ensure that the Merger and the
      Transactions are consummated.

    


    6. In
      addition to the rights and remedies given it by this Note, the Lender shall
      have
      all those rights and remedies under the Security Agreement dated March 31,
      2008
      between the Lender and the Borrower as well as those allowed by applicable
      laws.
      The rights and remedies of the Lender are cumulative and recourse to one or
      more
      right or remedy shall not constitute a waiver of the others. The Borrower shall
      be liable for all commercially reasonable costs, expenses and attorneys’ fees
      incurred by the Lender in connection with the collection of the indebtedness
      evidenced by the Note. 

    


    7. To
      the
      extent permitted by applicable law, the Borrower waives all rights and benefits
      of any statute of limitations, moratorium, reinstatement, marshalling,
      forbearance, valuation, stay, extension, redemption, appraisement and exemption
      now provided or which may hereafter by provided by law, both as to itself and
      as
      to all of its properties, real and personal, against the enforcement and
      collection of the indebtedness evidenced hereby. 

    


    8. All
      notices, requests, demands, and other communications with respect hereto shall
      be in writing and shall be delivered by hand, sent prepaid by a
      nationally-recognized overnight courier service or sent by the United States,
      certified, postage prepaid, return receipt requested, at the addresses
      designated in the Bridge Loan Agreement or such other address as the parties
      may
      designate to each other in writing. 

    


    9. This
      Note
      or any provision hereof may be waived, changed, modified or discharged only
      by
      agreement in writing signed by the Borrower and the Lender. The Borrower may
      not
      assign or transfer its obligation hereunder without the prior written consent
      of
      the Lender. 

    


    10. The
      term
“the Borrower” shall include each person and entity now or hereafter liable
      hereunder, whether as maker, successor, assignee or endorsee, each of whom
      shall
      be jointly, severally and primarily liable for all of the obligations set forth
      herein. 

    


    11. If
      any
      provision of this Note shall for any reason be held invalid or unenforceable,
      such invalidity or unenforceability shall not affect any other provision of
      this
      Note, but this Note shall be construed as if this Note had never contained
      the
      invalid or unenforceable provision. 

    


    12. This
      Note
      shall be governed by and construed in accordance with the domestic laws of
      the
      State of New York, without giving effect to any choice of law provision or
      rule.
      Any controversy or dispute arising out of or relating to this Note shall be
      settled solely and exclusively in accordance with the provisions of the Bridge
      Loan Agreement and Security Agreement, which provisions are incorporated by
      reference herein as though fully set forth.
