Item 1.01         Entry Into a Material Definitive Agreement

     On February 15, 2006,  the Registrant  signed an Asset  Purchase  Agreement
(the  "Agreement") for the sale to The Reinforced Earth Company (the "Buyer") of
substantially all of the assets (excluding  receivables,  land and miscellaneous
items), of Registrant's  geotechnical  business (the  "Business").  The purchase
price  was $4  million  plus  the net  asset  value  of the  Business's  work in
progress,  inventory,  fixed assets and prepaid items.  The bulk of the purchase
price was paid at closing with the balance to be paid pursuant to a post closing
purchase price adjustment process. The closing occurred on Tuesday, February 21,
2006.

     The Agreement contains various representations,  warranties,  covenants and
conditions.  Registrant  has agreed  that  neither it nor its  affiliates  shall
compete with Buyer's geotechnical business for a period of five (5) years. Buyer
has  agreed  to  assume  and/or  perform  substantially  all of  the  Business's
contracts with respect to the period after the closing.

     Registrant  will file the  Agreement as an Exhibit to its annual  report on
Form 10-K for the year ended December 31, 2005.
