ITEM 1.01.    ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

     On July 26, 2005, Allen Drilling Acquisition Company, a wholly owned
subsidiary of Registrant ("ADAC") executed an "Amendment To Agreement" (the
"Amendment"), which Amendment modified certain provisions of the March 6, 2003,
agreement between ADAC and Gateway Energy Corporation as related to the
Madisonville Project Pipeline Facilities. The Amendment was necessary to enable
Gateway to sell certain of the Pipeline Facilities. The Amendment provides among
other things for; (a) a waiver of the notification by ADAC of it's election to
pay off the $900,000 Term Note and exercise of the Equity Participation Option;
(b) receipt by ADAC of certain consideration pursuant to a May 7, 2004 amendment
to the 2003 agreement, and; (c) the transfer to a newly formed LLC, which LLC
will be owned by ADAC (33.33%) and by Gateway (66.67%), of the 10"
Transportation System along with certain ancillary equipment, and a
Transportation Agreement between Gateway and the purchaser of the Pipeline
Facilities. The transactions are required to be closed and funded by August 31,
2005.
