     Pursuant to the Merger  Agreement,  all of the issued and  outstanding
shares of DeepTech  common  stock,  par value $0.01 per share,  immediately
prior to the Merger (the  "DeepTech  Common  Stock") was converted into the
right to receive $14.00 in cash, except that approximately 70,600 shares of
El Paso Energy  common  stock will be issued to holders of DeepTech  Common
Stock who  elected  to  receive El Paso  Energy  common  stock in a taxable

and was funded through existing credit facilities.
