      This

        is
        made and entered into as of July 3, 2007 (the “Effective
        Date”),
        by
        and between XA,

        a
        Nevada corporation (“XA”)
        and
Paul
        M. Higbee, an
        individual (the
        “Purchaser”),
        each
        individually a “Party”
and
        collectively the “Parties.”

      


      W I T N E S S E T H:

      


      WHEREAS,
        pursuant to a Securities Purchase Agreement entered into with the Purchaser
        on
        or about September 26, 2006, which was later amended and replaced by a
        Securities Purchase Agreement dated on or around October 26, 2006, to be
        effective as of September 26, 2006 (the “Prior
        Purchase Agreement”),
        XA
        sold the Purchaser a fifteen month 11% Senior Secured Convertible Promissory
        Note, which was later amended and replaced by a fifteen month 11% Senior
        Secured
        Convertible Promissory Note, dated on or around October 26, 2006, to be
        effective as of September 26, 2006 (the “Prior Notes”),
        in
        the amount of $100,000;

      


      WHEREAS,
        XA
        recently sold an additional $25,000 in twelve month 11% Senior Secured
        Convertible Promissory Notes on substantially similar terms as the Prior
        Notes
        to the Purchaser (other than the maturity date thereof and other revisions
        which
        were agreed by the Parties)(the “Follow
        On Notes”),
        in
        connection with the sale of an aggregate of $450,000 in additional notes
        (the
“Follow
        On Funding”);
        and

      


      WHEREAS,
        a
        negotiated term and provision of the Follow On Funding was the amendment
        of the
        maturity date of the Prior Notes to be equal to the maturity date of the
        Follow
        On Notes.

      


      NOW,
        THEREFORE,
        in
        consideration for the promises and pledges contained below and other good
        and
        valuable consideration, which consideration the Parties acknowledge receipt
        of,
        and the premises and the mutual covenants, agreements, and considerations
        herein
        contained, the Parties hereto agree as follows:

      


      

        
          	
                  1.

                	
                  AMENDMENT
                    TO MATURITY DATE OF THE PRIOR NOTES.

                
	 	 
	 	
                  XA
                    and the Purchaser each individually agree to amend and replace
                    the
                    definition of “Maturity Date” as defined in the introductory paragraph of
                    the Prior Notes to which they are a party, to June 11, 2008 (the
                    “Amendment”).
                    The Parties further agree that any mention to the term Maturity
                    Date in
                    the Prior Notes shall hereafter refer to June 11, 2008.


                
	 	 
	 	
                  The
                    Purchaser confirms that it received valid consideration from
                    the sale of
                    the Follow On Notes and that the Amendment was a required term
                    of such
                    Follow On Funding.

                
	 	 
	 	
                  XA
                    confirms that it will receive valid consideration from the
                    Amendment.
