         In September 1997, DeepTech International Inc. (the "Company") entered
into a restructuring agreement with Tatham Offshore, Inc. ("Tatham Offshore") to
arrange for the prepayment by Tatham Offshore of the aggregate principal amount
of $60 million under those certain Subordinated Convertible Promissory Notes
(the "Notes") held by the Company. Under the restructuring agreement, the
Company had the right to consummate one of three options to (i) convert the
Notes into common stock of Tatham Offshore, (ii) receive all of the capital
stock of Tatham Offshore Development, Inc. and certain rights under a drilling
order or (iii) receive preferred stock of Tatham Offshore, as payment in full by
Tatham Offshore of its debt to the Company under the Notes.
