it has  exercised  its right to  terminate  the  Letter of Intent to merge  with

disappointed  that  a  transaction  could  not be  consummated  which  would  be
beneficial  to both  parties.  However,  3DX is committed to manage  itself as a
successful  E&P  company.  Recent sales of a partial  interest in the  Company's
Ramrod project in Matagorda  County,  Texas and a non-core  producing asset have
strengthened  the financial  position of the Company.  We will continue to focus
and remain aggressive in pursuing those  opportunities that position our Company
for future success and growth."
