    Re: Amendment
      to Secured Convertible Debentures

    

    Dear
      Mr.
      Neher:

    

    This
      letter will memorialize the agreement by and between Wherify Wireless, Inc.,
      a
      Delaware corporation (the “Company”),
      and
      Cornell Capital Partners, LP, a Delaware Limited Partnership (the “Holder”),
      in
      connection with amendments to the March 10, 2006 7% Secured Convertible
      Debenture issued to the Holder in the original face amount of $2,500,000 and
      the
      March 14, 2006 7% Secured Convertible Debenture issued to the Holder in the
      original face amount of $2,500,000 (collectively referred to as the
“Convertible
      Debentures”).
      All
      capitalized terms herein, unless otherwise indicated, shall have the meaning
      ascribed to them in the Convertible Debentures. 

    

    The
      parties hereby amend the Convertible Debentures as follows:

    

    

    
      	1.  	
              Interest
                Payments.
                The Company shall, in its sole discretion, make any interest payment
                due
                in either (i) cash, or (ii) after the Effective Date, in common stock
                at
                the Fixed Conversion Price, provided that the effectiveness of the
                Underlying Share Registration Statement has not lapsed for any reason.
                In
                no circumstances shall the Holder have any discretion in whether
                interest
                paid by the Company is in the form of cash or in common stock.
                

            

    

    

    
      	2.  	
              Default
                Conversion Price.
                Section 3(c)(xii) of the Convertible Debentures shall be deleted
                in its
                entirety and replaced with the
                following:

            

    

    

    Section
      3(c)(xii).
      If an
      Event of Default occurs and remains uncured twelve months after the Original
      Issue Date (as defined in Section 5) of this Debenture, the Fixed Conversion
      Price shall be switched to the Default Conversion Price. The Default Conversion
      Price shall be equal to $0.65. The Obligor agrees that the date that full
      consideration was paid for this Debenture shall remain the Original Issue Date.
      The Company shall provide an opinion letter from counsel within two (2) days
      of
      written request by the Holder stating that the date full consideration was
      paid
      for this Debenture is the Original Issue Date. In the event that counsel to
      the
      Company fails or refuses to render an opinion as required to issue the
      conversion shares in accordance with this paragraph (either with or without
      restrictive legends, as applicable), then the Company irrevocably and expressly
      authorizes counsel to the Holder to render such opinion and shall authorize
      the
      Obligor’s transfer agent to accept and be entitled to rely on such opinion for
      the purposes of issuing the conversion shares.
