Item 1.01

On May 25, 2007,  Registrant  and R.L.R.  Investments,  LLC ("RLR")  executed an
amendment, which is attached hereto and incorporated herein by reference, to the
Purchase and Sale Agreement dated March 29, 2007  ("Agreement")  under which the
Registrant  agreed to sell to RLR  approximately  61.1931  acres of real  estate
located in Harris County, Texas. Under the Agreement,  RLR had until on or about
May 28,  2007 to  determine  if the real estate was  suitable  for RLR's use. On
April 3, 2007, the Registrant filed a Form 8-K describing the Agreement.

RLR has determined that certain  restrictions on permissible hours of operations
at the real estate may interfere with RLR's contemplated use of the real estate.
Accordingly,   RLR  requested  an  extension  of  time  to  determine  if  these
restrictions could be satisfactorily  modified. Under the May 25, 2007 amendment
to the  Agreement,  RLR now has until  June 27,  2007 to  determine  if the real
estate is  suitable.  If RLR,  in its sole  judgment,  determines  that the real
estate is not suitable, RLR may terminate the Agreement without penalty.
