ITEM 5.  OTHER EVENTS.

DeepTech International Inc. (the "Company") announced on July 21, 1997 that it
expects to reflect reduced equity earnings from two of its subsidiaries as a
result of asset write-downs at the subsidiary level.  The Company estimates
that its fourth quarter results will be reduced by $18 to $22 million on a
pre-tax basis to reflect the write-downs at Tatham Offshore, Inc. and Leviathan
Gas Pipeline Partners, L.P.

"The reductions at Tatham Offshore and Leviathan are of a non-recurring nature
and will not impact the operational prospects of either Tatham Offshore or
Leviathan.  The business prospects of both companies have tremendous growth
potential and we look forward to reporting on their success in the future,"
stated Thomas P. Tatham, Chairman and Chief Executive Officer of DeepTech.

DeepTech has an effective 23.2% ownership interest in Leviathan Gas Pipeline
Partners, L.P. (NYSE: LEV).  DeepTech also has an approximate 37% interest in
Tatham Offshore, Inc. (Nasdaq: TOFF), whose wholly-owned subsidiary, Tatham
Offshore Canada, Ltd. is the Canadian representative of North Atlantic Pipeline
Partners, L.P.  North Atlantic is the sponsor of a proposal to build an
offshore pipeline from the Grand Banks area of Newfoundland to New England.
