    Ladies
      and Gentlemen:

    


    Reference
      is hereby made to that certain June 2008 Amendment Agreement (the “Amendment

      dated
      as of June 12, 2008, by and among Customer Acquisition Network Holdings, Inc.
      (the “Company”),
      the
      Subsidiaries and Longview Marquis Master Fund, L.P. (“Buyer”).
      Capitalized terms used, but not otherwise defined, herein shall have the
      meanings ascribed to them in the Amendment Agreement.

    


    Buyer
      and
      the Company and the Subsidiaries hereby agree that (i) the reference to “June
      20, 2008” in Section 1(a) of the Amendment Agreement with respect to the
      amended definition of “Maturity
      Date”
in
      the
      Buyer Note shall be changed to “June 25, 2008,” (ii) the reference to “June 20,
      2008” in Section 2(a)(xi) of the Amendment Agreement with respect to the Options
      Sale Closing Date shall be changed to “June 25, 2008,” and (iii) the reference
      to “June 23, 2008” in Section 6 of the Amendment Agreement with respect to the
      filing deadline for the Amendment Form 8-K shall be changed to “June 27,
      2008.”

    


    Buyer
      and
      the Company and the Subsidiaries hereby agree that clause (vii) of Section
      2(a)
      of the Amendment Agreement is amended in its entirety to read as
      follows:

    


    “(vii)
      the Options Purchaser, by operation of law or otherwise, accepts and assumes,
      and the Company and its subsidiaries are released from, all of the obligations
      and liabilities of any nature of Options or otherwise related to the Options
      Business or the Options Assets, whether fixed or unfixed, known or unknown,
      secured or unsecured, absolute, accrued, contingent or otherwise and whether
      due
      or to become due (including account payables and any remaining “earn-out”
obligations incurred in connection with the Company’s initial acquisition of the
      Options Business pursuant to that certain Agreement and Plan of Merger, dated
      as
      of January 4, 2008 (the “Options Merger
      Agreement”),
      among
      the Company, Options and Options Newsletter, Inc. (“Newsletter”));
      other than the obligations and liabilities of Options with respect to the
      current and future “earn-out” obligations owed to Mr. Hagai Shechter pursuant to
      the Options Merger Agreement, which obligations shall not be in excess of
      $1,000,000;”

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    Buyer
      and
      the Company and the Subsidiaries hereby acknowledge and agree that,
      notwithstanding anything to the contrary set forth in Section 2(a)(iii) of
      the
      Amendment Agreement and as a condition to Buyer’s consent to the Options Sale
      and the agreement to release of security agreement contemplated by the Letter
      Agreement, in any event, a portion of the Cash Proceeds is used by the Company
      to redeem at least $2,700,000 of the Principal of the Buyer Note, in accordance
      with Section 3(b) of the Buyer Note, by wire transfer of immediately available
      funds to Buyer, contemporaneously with the consummation of the Options
      Sale.

    


    The
      Company hereby covenants, following the Condition Satisfaction Date, to
      promptly, and in no event later than three (3) Business Days following the
      Condition Satisfaction Date, issue to Buyer an amended and restated Buyer Note,
      in a form acceptable to Buyer, reflecting the terms of the Buyer Note as amended
      by the Amendment Agreement (the “New
      Note”).
      Upon
      the issuance by the Company to Buyer of the New Note, the Buyer Note previously
      held by Buyer (the “Original
      Note”)
      will
      be void and of no further force and effect, and Buyer shall promptly return
      the
      Original Note to the Company for cancellation.

    


    As
      modified hereby, the Amendment Agreement remains in full force and
      effect.
