     "To assert a claim arising out of a breach of Seller's
     representation and warranty of Defensible Title in Section
     3.1(a), Purchaser must deliver claim notices to Seller (each
     a "Title Defect Notice") on or before Tuesday, April 26,

     to Seller, Seller shall have the option, at its sole
     election, to extend the Closing Date until May 10, 2005 at
     10:00 a.m. local time. In the event that Seller elects to
     extend the Closing Date, Seller shall give written notice of
     such extension to Purchaser as provided in the Agreements."

      As amended  herein, the Agreements are hereby adopted,
ratified and confirmed as being in full force and effect pursuant
to their terms.
