Item 1.01   Entry into a Material Definitive Agreement.

                    On December 28, 2009,  the  Registrant  entered into a stock

          satisfaction  of certain  conditions,  including  the  consent  and/or
          approval of certain  third  parties  with  respect to the  transfer or
          assignment of certain  contractual  obligations and other liabilities,
          the stock purchase  agreement  provides for the sale to the Registrant
          or its designee of all of the issued and outstanding  capital stock of

          $1,500,000.00  for the  assumption  of  certain  expenses.  The  final
          purchase  price is subject to certain  adjustments  related to working
          capital.  As part of the stock purchase  agreement,  the Registrant or
          its designee shall also be acquiring all of the issued and outstanding

          is owned by Cinch  U.S and  0.1% of  which  will be  transferred  from
          Labinal Investments, Inc., an affiliate of the Sellers.

                    The   Cinch   Companies   manufacture   a  broad   range  of
          interconnect  products for  customers  in the military and  aerospace,
